Branch or Subsidiary in Hong Kong in 2026: What a Foreign Business Should Choose

A branch of a foreign company in Hong Kong is legally a registered non-Hong Kong company: the same foreign company, registered with the Companies Registry under Part 16 of the Companies Ordinance (Cap. 622) once it has established a “place of business” in Hong Kong. A subsidiary is a separate Hong Kong legal entity (usually a private company limited by shares) incorporated under Part 3 of the same Ordinance and owned by the foreign parent. The difference between the two lies not in the tax rate (profits tax is identical: 8.25% on the first HK$2,000,000 of assessable profits and 16.5% above that) but in three things: who is liable for the obligations, how much compliance has to be maintained, and how the structure looks to banks, counterparties and the tax authorities of the parent’s home country. Registering a branch costs HK$1,545 on electronic filing and takes about 9–10 working days; incorporating a subsidiary costs the same HK$1,545 and takes about an hour online; in both cases a business registration fee of HK$2,350 for one year is paid on top.

Important. The duty to register a branch arises automatically: under section 776 of Cap. 622, a foreign company that has established a place of business in Hong Kong must apply for registration within one month. Non-compliance is a criminal offence for the company itself, every responsible person and every agent who authorizes or permits the contravention: a fine at level 5 (HK$50,000) plus HK$1,000 for every day the offence continues. Among other consequences, an unregistered company cannot register charges over Hong Kong property with the Companies Registry.

The legal framework: which instruments govern branches and subsidiaries in September 2026

The legal framework for branches and subsidiaries in Hong Kong consists of one principal statute (the Companies Ordinance, Cap. 622) with several pieces of subsidiary legislation, plus separate ordinances on business registration, tax and stamp duty. Every instrument below is in force as at September 2026; repealed versions (the Companies Ordinance Cap. 32 in its company-law part, including the former Part XI “Oversea Companies”) are not relied upon in this article and are mentioned only where the current statute itself refers to them as the “predecessor Ordinance”.

The key date for every branch calculation is 3 March 2014: Part 16 has been in operation since that day, and the Companies Ordinance uses it to determine which companies count as “non-Hong Kong companies”. The key date of 2025 is 23 May: from that day the re-domiciliation regime has been in operation, adding new duties for branches (notifying a change of place of incorporation) and offering a third way of being present — moving the company itself to Hong Kong.

What a registered non-Hong Kong company is, and how a branch differs from a subsidiary and a representative office

A registered non-Hong Kong company is, under section 2(1) of Cap. 622, a company incorporated outside Hong Kong (other than a re-domiciled company) that has established a place of business in Hong Kong and is registered in the Companies Register in that capacity. In business usage the registration is called a “branch”, but the essential point is that the Companies Ordinance creates no new legal person. Registration under Part 16 merely records in Hong Kong’s public register that the foreign company is present here, who its directors are, where its place of business is and who in Hong Kong is authorized to accept service of court documents on its behalf.

A subsidiary is a company incorporated under Part 3 of Cap. 622 (usually a private company limited by shares) whose shares are held by the foreign parent. It has its own registry number, its own directors, its own constitutional document (the articles of association), its own accounts and its own liability for its obligations: under section 2(1) of Cap. 622 the term “company” covers only companies formed and registered under the Ordinance, “existing companies” and re-domiciled companies — a branch is not among them.

A representative office (also called a liaison office) is an office of a foreign company that concludes no contracts and carries on no income-generating activity. Under established practice such an office is not registered with the Companies Registry: the Inland Revenue Department’s guide to business registrationrequires a non-Hong Kong corporation that has a representative or liaison office in Hong Kong only to obtain a business registration certificate, and Cap. 622 contains no separate exemption for representative offices (the only express exclusion from “place of business” is a bank’s local representative office under section 774(3)). Baker McKenzie’s guide “Doing Business in Hong Kong” (2025 edition; the current 2026 edition was published on 13 February 2026) notes that this format is appropriate only where the foreign corporation does not intend to enter into or perform contracts with customers in Hong Kong and confines its Hong Kong activities to gathering and disseminating information and liaising with customers; the Inland Revenue Department will then normally grant an exemption from filing further tax returns.

The difference between the three formats is clearest through the lens of liability. A branch’s debt is the debt of the foreign company itself: a Hong Kong creditor can enforce against any of its assets wherever located, and foreign creditors can, in turn, reach the Hong Kong assets. A subsidiary’s debt is the subsidiary’s alone: the shareholder’s liability is limited to any amount unpaid on its shares, unless it has given guarantees. A representative office creates no commercial obligations to customers because it carries on no business, but its rent, salaries and MPF contributions are debts of the foreign company itself.

According to the Companies Registry, 903 foreign companies established a place of business in Hong Kong in the first half of 2026, and the total number of registered non-Hong Kong companies reached 16,014 — an all-time high. For comparison, 122,481 local and re-domiciled companies were newly registered over the same period, and the total number of companies on the register stood at 1,609,720 (press release of 17 July 2026). In other words, the branch remains a niche instrument: for every Part 16 registration there are more than a hundred incorporations of local companies.

Representative office: when Business Registration Office registration is enough, and when it turns into a branch

A representative office (or liaison office) is an office of a foreign company in Hong Kong that carries on no income-generating activity. Cap. 622 provides no separate status for it; under the established practice described by Baker McKenzie in its “Doing Business in Hong Kong” guide (2025 and 2026 editions), registration of such an office with the Companies Registry is not required — it is registered only with the Business Registration Office under Cap. 310. The statute draws no line between a “representative office” and a “place of business”, so the format is safe only if the limits described below are strictly observed. The IRD guide to business registration states that every non-Hong Kong corporation that has a representative or liaison office in Hong Kong, or lets out its Hong Kong property, must register under the Business Registration Ordinance; the application is made within one month of commencing business on Form 1(b), which, as the IRD notes, applies to all non-Hong Kong companies whether or not they are required to register under Part 16; Baker McKenzie recommends stating the nature of business in the application as “representative/liaison office”.

Those limits are narrow. Baker McKenzie describes the format as appropriate only for a company that does not intend to enter into or perform contracts with customers in Hong Kong and confines its Hong Kong operations to non-profit-making activities — disseminating and gathering information and liaising with customers and potential customers; where that condition is met, the Commissioner of Inland Revenue will normally grant the company an exemption from filing further returns. A representative office cannot issue invoices, sign supply or service contracts, accept payment, hold stock for sale or provide paid after-sales service.

The fees are the same as for a branch or a subsidiary: a business registration certificate at HK$2,350 for one year or HK$6,170 for three years, displayed in a conspicuous place. There are no annual returns to the Companies Registry and no authorized representative to appoint — but equally no capacity to carry on business. Staff of a representative office are employed by the foreign company directly, and the Employment Ordinance and the MPF regime apply to the company in full.

A representative office turns into a branch the moment the office begins to carry on the company’s business: the first contract signed in Hong Kong, the first invoice issued or the first delivery from a warehouse is the “establishment of a place of business” from which the one-month period under section 776 runs. The transition from representative office to branch should therefore be planned in advance — the certified documents assembled and the authorized representative appointed before the first transaction, not after. The reverse transition, from branch to representative office, is legally more delicate: a Form NN13 notice under section 794 is a statement that the company has ceased to have a place of business in Hong Kong, and it can be filed while an office is kept open only after a legal assessment that the remaining activity does not amount to a place of business; the nature of business is changed at the Business Registration Office separately.

When the duty to register arises: “place of business” and the one-month period under section 776

A place of business is, under section 774(1) of Cap. 622, a term that includes a share transfer office and a share registration office but excludes a local representative office of a bank established with the approval of the Monetary Authority under section 46 of the Banking Ordinance (Cap. 155). The statute gives no exhaustive definition, and that is the main source of error: companies assume that “just a rented office with one manager” is not yet a branch, while the one-month clock is already running.

The duty to register is set out in section 776 of Cap. 622 for three situations: a company that establishes a place of business in Hong Kong on or after 3 March 2014 (subsections (1)(a) and (2)); a company that had a place of business before that date and had not complied with section 333 of the predecessor Ordinance (subsections (1)(b) and (3)); and a company that re-domiciled to Hong Kong and whose re-domiciliation registration was later revoked under section 820F (subsections (1)(c) and (3A), added by Ordinance No. 14 of 2025). In all three cases the period is the same — one month after the establishment of the place of business, after the commencement of Part 16, or after the revocation order takes effect.

The statute does not list the attributes of a place of business, but it requires the place to be named specifically: Form NN1 must state the date on which the place of business in Hong Kong was established and the address of the principal place of business (section 3(1)(c) and (f) of Cap. 622J), and it is from that date that the one-month registration period and all subsequent annual obligations are counted. The definition in section 774(1) is built on an “includes but is not limited to” basis: since it captures even share transfer and share registration offices, where no trading takes place, any permanent premises from which the company operates in Hong Kong should be treated as a candidate for registration.

In our assessment, what does not normally require Part 16 registration: selling goods to Hong Kong buyers from abroad without an office, engaging an independent distributor, renting warehouse space from a logistics operator without staff of one’s own, or holding the shares of a Hong Kong subsidiary as such. What normally does: an office with employees, a showroom, a service centre, a regional headquarters, a fund manager’s or broker’s office, a warehouse with one’s own personnel. Borderline cases — a dedicated desk in a co-working space, an employee working from home under a Hong Kong employment contract — are best not assessed without professional advice: the price of getting it wrong is a level 5 fine and HK$1,000 a day. UPPERSETUP makes that assessment — whether the planned presence constitutes a place of business, and from what date — before the lease is signed, as part of its legal and strategic consulting.

Liability for contravening section 776 extends beyond the company to every “responsible person” and every agent who authorized or permitted the contravention: a fine of up to HK$50,000 plus HK$1,000 for every day the offence continues (section 776(6)). There is a procedural consequence too: under section 803(5), process addressed to a foreign company that has not registered is sufficiently served if left at its place of business in Hong Kong, and the Companies Registry, as its guidance on registration of charges makes clear, will not accept for registration charges created by non-Hong Kong companies that have not registered under the Companies Ordinance.

How to register a branch: Form NN1, documents, certification, timing and fees

Branch registration is the delivery to the Companies Registry of an application on Form NN1 with a set of certified documents, after which the Registrar must (section 777) register the company and issue a Certificate of Registration of Non-Hong Kong Company. The Registrar does not assess the merits of the presence: under section 777(1), on receiving an application under section 776 the Registrar must register the company. The Registrar may, however, refuse to accept unsatisfactory documents — incomplete, untranslated or non-compliant (sections 31 and 35 of Cap. 622) — and, after registration, check the name under section 780, discussed below.

The particulars are prescribed by section 3 of Cap. 622J: the company’s domestic name (if in Latin characters or Chinese), its place of incorporation, the date on which the place of business in Hong Kong was established, particulars of each director (date of appointment, names, usual residential address and correspondence address, identity card or passport number) and of the company secretary, and three addresses — the principal place of business in Hong Kong, and the principal place of business and the registered office in the place of incorporation. In addition, under section 776(4)(c) the application must contain the “required details” of at least one authorized representative in Hong Kong.

The documents are prescribed by section 4 of Cap. 622J and confirmed by the Companies Registry’s FAQ:

1.       a certified copy of the company’s constitution (charter, statutes, memorandum and articles) and, if it is not in English or Chinese, a certified translation;

2.       a certified copy of each “specified certificate” — the certificate of incorporation (or its equivalent) and, if the company transferred its domicile after incorporation, the document certifying its registration in the new jurisdiction; if the certificate is not in English or Chinese, both a certified copy of the original and a certified translation are delivered;

3.       a certified copy of the latest published accounts, if the law of the place of incorporation requires the accounts to be published or delivered for public inspection; if no such requirement exists either in the place of incorporation or under the rules of a stock exchange elsewhere — a statement in the specified form to that effect; if the company has existed for less than 18 months and the accounts have not been made up — a statement to that effect (section 4(4));

4.       a Notice to Business Registration Office (Form IRBR2): an application for registration under Part 16 is deemed to be a simultaneous application for business registration, so the business registration fee and levy are paid together with the NN1.

The name deserves particular attention. Under section 776(5) of Cap. 622, if none of the company’s domestic names is in Latin characters or Chinese, the application must include a certified translation of the name into English or Chinese (or both). This directly affects companies from Russia, Kazakhstan, Belarus and other countries with Cyrillic names, as well as companies with Arabic names from the UAE: without a certified translation registration is impossible, and the translation must be accompanied by a certified translation of the relevant part of the certificate of incorporation (section 7 of Cap. 622J).

Who may certify copies is determined by section 775 of Cap. 622. In the place of incorporation: the government official holding the original, a notary public, a practising lawyer, a professional accountant, an authorized court officer or a professional company secretary; in Hong Kong: a notary public, a solicitor, a certified public accountant (practising), a court officer, a consular officer of the place of incorporation or a professional company secretary; in addition, a copy may be certified by an officer of the company itself or by its authorized representative in Hong Kong. Apostille and consular legalisation are not mentioned in Cap. 622 — certification by one of the listed persons suffices, although banks often ask for more when opening an account.

The fee for registering a branch is HK$1,545 on electronic filing (a HK$1,280 registration fee plus a non-refundable HK$265 lodgment fee) and HK$1,720 on paper filing (HK$1,425 plus HK$295). The rates are set by Part 3 of Schedule 1 to the Companies (Fees) Regulation (Cap. 622K); the 10% discount for electronic filing has applied since 1 October 2020. The business registration fee and levy are added: under the IRD table, for certificates commencing between 1 April 2026 and 31 March 2027 a one-year certificate costs HK$2,350 (a HK$2,200 fee plus a HK$150 levy) and a three-year certificate HK$6,170.

Timing: according to the e-Services Portal FAQ, the certificate can normally be issued within 10 working days after submission, while the Companies Registry pamphlet PAM 14E (May 2025) cites 9 working days — so the realistic benchmark is 9–10 working days with a complete set of documents. The certificate is issued in electronic form only (PDF) and remains available for download for six months. Since 27 December 2023 the number shown on the certificate has been the 8-digit business registration number — the unified business identifier (UBI) that replaced the former company number.

For comparison, incorporating a subsidiary costs the same HK$1,545 (electronic) or HK$1,720 (paper), uses Forms NNC1 and IRBR1 with a copy of the articles of association, and, according to the Companies Registry’s FAQ, the certificates of incorporation and business registration are normally issued within one hour of electronic delivery and within four working days of paper delivery. The difference in timing is easily explained: for a subsidiary the Registrar checks only the form and the uniqueness of the name; for a branch, a set of foreign documents and translations.

UPPERSETUP’s experience is that the longest stage of a branch registration is not the Companies Registry but the preparation of documents in the parent’s home country: obtaining fresh certified copies of the constitution and certificate, translation, and the resolution appointing the authorized representative. For how the incorporation of a local company works and what the annual cycle looks like afterwards, see Hong Kong Company Registration 2026: Requirements, Procedure, Taxes, and Annual Compliance.

Authorized representative, name and disclosure: what a branch must maintain at all times

An authorized representative is, under section 774(1) of Cap. 622, a person authorized to accept on the company’s behalf service of any process or notice required to be served on it. Only five kinds of person qualify: a natural person resident in Hong Kong; a solicitor corporation; a corporate practice under the Accounting and Financial Reporting Council Ordinance (Cap. 588); a firm of solicitors; or a CPA firm under the same Cap. 588 (a firm of practising CPAs has been eligible since 2014; since L.N. 66 of 2022 the category is defined by reference to Cap. 588). An ordinary corporate services company that is neither a solicitors’ practice nor a CPA firm cannot act as the representative — a frequent mistake when choosing a provider.

The representative is not a formality but the sole point of contact between the authorities and creditors, on the one hand, and the branch, on the other. Under section 803(1), process is sufficiently served on a branch if addressed to the representative and left at or posted to the representative’s last known address in Hong Kong; under section 796, it is to the representative that the Registrar sends an inquiry letter when it suspects that the branch has ceased business. The statute therefore requires continuity: if the only registered representative ceases to act, the company must deliver particulars of a replacement within one month (section 786), failing which a level 5 fine and HK$1,000 a day apply. Termination is effected by written notice, which the sender must report to the Registrar within one month (section 787), and takes effect no earlier than 21 days after that notification.

A branch’s corporate name is its domestic name, or a certified translation of it, as entered in the Companies Register (section 774(1)). The Registrar does not vet the name before registration but may serve a notice if the name is the same as or too like a name in the Index of Company Names (such a notice may be served only within 6 months after the certificate is issued — section 780(3)), or if the name gives so misleading an indication of the nature of the company’s activities in Hong Kong as to be likely to cause harm to the public (no time limit for this ground — section 780(1)(b)). After such a notice the branch has 2 months to stop carrying on business under that name (section 781); contravention is a level 6 fine (HK$100,000) plus HK$2,000 a day, although transactions entered into under the disputed name remain valid. The way out is to obtain an “approved name” under section 782 (HK$1,425 for the fresh certificate) or to appeal to the Administrative Appeals Board within 3 weeks (section 784, available only for notices about misleading names).

Disclosure by a branch is governed by a separate regulation — Cap. 622M, in operation since 1 August 2019 (not to be confused with Cap. 622B, which applies to local companies). A branch must: display continuously and conspicuously its name and each place of incorporation at every “business venue” (an office or place in Hong Kong open to the public where it carries on business, and its principal place of business in Hong Kong — section 3); state its name and each place of incorporation in every business letter, notice, official publication, contract, deed, bill of exchange, promissory note, endorsement, cheque, order for money or goods, consignment note, invoice, receipt and letter of credit — in hard copy and electronic form alike (sections 2(1) and 4); and, if its members’ liability is limited, exhibit a notice of that fact at every business venue and state it in all the listed documents (section 5). Contravention is a level 3 fine (HK$10,000) for the company, every responsible person and every agent (section 8). After the 2025 amendments, “place of incorporation” includes both the original jurisdiction and the jurisdiction of the latest domicile if the company has moved.

In practice this means that an invoice issued by the Hong Kong branch of a Russian or Kazakh company must carry, for example: “OOO Primer (Limited Liability Company, Russian Federation) — a company incorporated in the Russian Federation with limited liability, registered in Hong Kong as a non-Hong Kong company”. A subsidiary in the same situation simply states its name with “Limited” — the requirements of Cap. 622B are simpler.

The branch’s annual obligations: NN3 within 42 days, accounts under section 789, notifications of changes and penalties

A branch’s annual return (Form NN3) is, under section 788 of Cap. 622, a mandatory yearly document delivered to the Companies Registry within 42 days after each anniversary of the date on which the certificate of registration was issued. The period runs not from the financial year and not from the parent’s date of incorporation but from the Hong Kong registration — a date that should go into the corporate calendar on the day the certificate arrives.

The contents of the NN3 are prescribed by section 9 of Cap. 622J: the date of the return (the most recent anniversary of registration), the place of incorporation, the corporate or approved name, the date and number of registration, the three addresses, particulars of the directors (without residential addresses and without full identification numbers — since L.N. 100 of 2021), of the company secretary and of the authorized representatives, a statement about the accounts, particulars of authorized and issued share capital, and the total indebtedness in respect of charges registered under Part 8.

The annual registration fee for a branch’s return is HK$180 if delivered within 42 days; if late, it rises to HK$1,200 (up to 3 months), HK$2,400 (up to 6 months), HK$3,600 (up to 9 months) and HK$4,800 (more than 9 months). By comparison, a local private company pays HK$105 for its NAR1, with a late-filing scale of HK$870, HK$1,740, HK$2,610 and HK$3,480 (Parts 1 and 3 of Schedule 1 to Cap. 622K). Beyond the higher fee, late delivery is a criminal offence: a level 5 fine (HK$50,000) plus HK$1,000 a day for the company, its responsible persons and agents, and a magistrate may additionally order delivery of the return within a set time (section 788(3)–(5)). The Companies Registry states expressly that it cannot extend the 42-day deadline (annual return page).

A branch’s accounts are dealt with by section 789: a certified copy of the latest published accounts for a period of at least 12 months must accompany the NN3, but only if the company is required to publish its accounts, or deliver them for public inspection, under the law of its place of incorporation or under the law of another jurisdiction where it is registered or the rules of a stock exchange there. If there is no such requirement, no exemption need be applied for — the relevant box in Section 12B of Form NN3 is simply ticked (Companies Registry FAQ); if the company has existed for less than 18 months and its accounts have not been made up, a different box in the same section is ticked. Accounts not in English or Chinese are delivered in certified translation. Note that these are the accounts of the whole company, not of the branch, and accounts that have already been published — Cap. 622 requires neither the preparation nor the audit of separate accounts for the Hong Kong branch. Whether section 789 applies to a particular parent depends on its home law: in our assessment, a Russian OOO, which must file its annual accounts with the publicly accessible state register (GIR BO), falls within section 789(1)(a) and must attach a certified translation of its accounts to every NN3; for a Kazakh TOO the answer depends on whether it is required to place its accounts in the financial statements depository; a UAE company with no publication requirement ticks the Section 12B box. This question is worth closing with a written opinion before the first NN3 is filed.

Notifications of changes are delivered within one month of the event (section 791): a change of the constitution — Form NN5 with a certified copy of the new text; appointment or cessation of a director or company secretary — NN6, and changes in their particulars — NN7; appointment or cessation of an authorized representative — NN8, and changes in the representative’s particulars — NN8C; a change of any of the three addresses — NN9; a change of name — NN10 under section 778 (HK$1,425 for the fresh certificate); a change of the place of incorporation — since 23 May 2025 a separate ground under subsection (2)(e). No fees are charged for NN5–NN9 (list of forms and deadlines). The penalties are graduated: failure to notify a change of the constitution — level 3 plus HK$300 a day; of directors, secretary or representatives — level 4 (HK$25,000) plus HK$700 a day; of addresses or the place of incorporation — level 5 plus HK$1,000 a day.

Separate deadlines apply: commencement of the foreign company’s liquidation and appointment of a liquidator — 15 days (section 793); dissolution of the company — 15 days, with the notice given by the authorized representative (section 795); cessation of the place of business in Hong Kong — 7 days on Form NN13 (section 794). Charges over Hong Kong property are registered under Part 8 within one month on Form NM1 with a certified copy of the instrument (fee HK$340).

What happens to a branch when the parent changes: liquidation, dissolution, change of domicile and constitution

A branch’s dependence on its parent is a direct consequence of its not being a separate person: every corporate event abroad creates a duty in Hong Kong, and some events terminate the registration automatically. Cap. 622 sets four different deadlines for such events, and they are the ones most often confused.

A change of the constitution, of the directors or company secretary, of the addresses or of the place of incorporation — notification within one month under section 791, with a certified copy of the new constitution (where it has changed) and a translation if the document is not in English or Chinese (section 14 of Cap. 622J). A change of the place of incorporation is a new ground added on 23 May 2025: if the parent has moved, say, from the British Virgin Islands to the Cayman Islands, the branch must report it within a month on pain of a level 5 fine and HK$1,000 a day (section 791(2)(e), (8)), and from then on both places of incorporation are disclosed under Cap. 622M.

Commencement of the parent’s liquidation (voluntary or compulsory) — notice within 15 days after the later of two dates, the commencement of the proceedings or the service on the company of notice of them under the law of the place of liquidation; where a liquidator is appointed, the liquidator’s particulars are given, and every change triggers a further 15 days (section 793; level 3 fine plus HK$300 a day). Cap. 622M requires “(in liquidation)” to be added to the name in documents and advertisements.

Dissolution of the parent — notice within 15 days, delivered by the authorized representative with a certified copy of the instrument effecting the dissolution (section 795); once the statement is entered, the company is no longer a registered non-Hong Kong company. Liability under section 795 falls on the authorized representative alone (level 3 plus HK$300 a day), who has a defence if it establishes that it did not know, and had no reason to believe, that the company had been dissolved (section 795(5)).

A change of the parent’s name — a return within one month (section 778) with a fresh certificate at HK$1,425; if the new name is in Cyrillic or Arabic script, with a certified translation. Since 23 May 2025 section 778A also applies: if the company re-domiciles to Hong Kong before delivering the return on the change of name, the duty and the liability survive as if it were still a branch.

A subsidiary is formally independent of all these events: the parent’s liquidation or dissolution concerns its shareholder, not the subsidiary’s own status, although in practice the shares will pass to the liquidator or successor, which requires the SCR to be updated and, on a change of shareholder, stamp duty to be paid. It is precisely this autonomy that makes a subsidiary preferable for groups whose parent plans a reorganisation, a sale or a re-domiciliation to another jurisdiction.

What a subsidiary must do: company secretary, natural-person director, audit, NAR1 and the significant controllers register

A Hong Kong subsidiary is a fully-fledged local company, and the entire corporate regime of Cap. 622 applies to it without any carve-out for “foreign ownership”: the statute does not distinguish between a company with a Hong Kong shareholder and one with a foreign shareholder. Four obligations that a branch does not have account for most of the difference in running costs.

The first is the officers. Under section 457 a private company must have at least one director who is a natural person (a corporate director is permitted only in addition to that natural person), and under section 474 a company secretary — a natural person ordinarily resident in Hong Kong, or a body corporate with its registered office or a place of business in Hong Kong. Secretarial services for foreign owners are provided by licensed TCSP providers; who needs that licence is explained in The Hong Kong TCSP Licence in 2026: Who Must Hold One, the Fit and Proper Test, the CDD Duties and What Enforcement Actually Costs.

The second is a registered office in Hong Kong under section 658, to which all communications and notices may be addressed; a change of address is notified within 15 days, and contravention is a level 5 fine plus HK$1,000 a day.

The third is financial statements and audit. Under section 379 the directors must prepare financial statements for each financial year (a wholly owned subsidiary of another body corporate may dispense with consolidated statements — section 379(3)(a)), and under section 405 the auditor must report on them. There is no size-based audit exemption in Hong Kong: small private companies enjoy only a simplified reporting format (the reporting exemption), not an exemption from appointing an auditor. The same audit is needed by the Inland Revenue Department: for a local corporation, audited financial statements accompany the BIR51 return as a general rule.

The fourth is the significant controllers register (SCR). Under section 653H in Division 2A of Part 12 of Cap. 622 the duty to keep an SCR falls on an “applicable company” (defined in section 653A), that is, a company within section 2(1) — and a branch is not a company, so the SCR does not apply to it. A subsidiary has had to keep the register since 1 March 2018, to appoint a designated representative and to enter the parent as a registrable legal entity and the individual beneficial owners as registrable persons. The register is covered in detail in The Significant Controllers Register in Hong Kong: Obligations, Deadlines and Penalties in 2026.

A subsidiary’s annual return (NAR1) is delivered under section 662 within 42 days after the anniversary of incorporation (except in the year of incorporation) with a HK$105 fee; the penalties for late delivery are the same as for a branch — level 5 plus HK$1,000 a day. The full annual cycle of a local company is described in Mandatory Annual Compliance for Hong Kong Companies 2026: Annual Return (NAR1), Audit, and Profits Tax Return (BIR51), and the directors’ personal exposure in Directors’ Duties and Liabilities under the Companies Ordinance (Cap. 622) in Hong Kong in 2026.

Tax: the same rate, different mechanics — profits tax, two-tiered rates, Part 8AA and the Certificate of Resident Status

Profits tax is Hong Kong’s tax on profits, charged under section 14 of the Inland Revenue Ordinance (Cap. 112) on every person carrying on a trade, profession or business in Hong Kong in respect of profits arising in or derived from Hong Kong. The rate is the same for a branch and a subsidiary: 16.5% for corporations, or under the two-tiered regime 8.25% on the first HK$2,000,000 of assessable profits and 16.5% on the remainder. The differences begin at the level of mechanics.

The first difference is the taxpayer. With a branch, the taxpayer is the foreign company itself: under section 50AAK(1) of Cap. 112, a non-Hong Kong resident person that has a permanent establishment in Hong Kong is regarded as carrying on business in Hong Kong for profits tax purposes. The BIR51 return is filed in the name of the foreign company, not of “the branch”. With a subsidiary, the taxpayer is the subsidiary, separately from its parent.

The second difference is what exactly is taxed. For a subsidiary — its own profits per its own accounts, adjusted under the territorial source principle. For a branch — the profits attributed to the permanent establishment under “Rule 2” in section 50AAK: the income or loss is determined as if the permanent establishment were a distinct and separate enterprise engaged in the same or similar activities under the same or similar conditions and dealing wholly independently with the rest of the company, taking into account the functions performed, assets used and risks assumed; dealings between the permanent establishment and other parts of the company are treated as taking place on arm’s length terms, and no deduction is allowed for costs in excess of that standard (section 50AAK(2)–(6)). An assessor may require proof of the amount attributed and, if it is not proved, estimate it (section 50AAK(7)–(10)). The IRD’s practice is set out in DIPN 60 (July 2019; Rule 2 applies from 1 April 2019); Part 8AA itself is covered in Transfer Pricing in Hong Kong 2026: Part 8AA of Cap. 112, Sections 50AAF and 50AAK, Master and Local Files, DIPN 58/59/60. A subsidiary has no such issue, but its dealings with the parent fall under “Rule 1” (section 50AAF) and, above the thresholds, under master file and local file documentation.

The third difference is the two-tiered rates. Under the IRD’s FAQ, the 8.25% rate on the first HK$2,000,000 may be claimed by only one of a group of “connected entities”: entities are connected if one controls the other or both are under the control of the same entity, and control means more than 50% of the issued share capital or voting rights. If a group has both a branch of the parent and a subsidiary in Hong Kong, the connected entities are the foreign company itself (it, not “the branch”, is the taxpayer and the “entity” under section 14AA of Cap. 112) and the subsidiary it controls; only one of them can elect the two-tiered rates; a duplicate election leads to additional assessments and penalties for an incorrect return.

The fourth difference is audit for tax purposes. Under the IRD’s rules on completing profits tax returns, a corporation must submit audited financial statements with its BIR51 in all cases except three: a dormant company; a company incorporated in a jurisdiction whose laws do not require an audit, where no auditor’s report has been prepared; and the Hong Kong branch of a foreign company — provided that four items of information accompany the return: the place of incorporation of the foreign company; whether the laws of that country require a statutory audit of its world-wide financial statements; whether that audit has been conducted; and a brief summary of the financial and accounting records maintained by the Hong Kong branch. In other words, a branch submits its own unaudited branch accounts to the IRD, while a subsidiary submits audited financial statements; UPPERSETUP prepares both kinds of accounts, including the four accompanying items for a branch, as part of its Accounting Support for Companies service. Baker McKenzie’s 2025 edition of “Doing Business in Hong Kong” puts it plainly: “These branch accounts do not need to be audited.” How the BIR51 forms, the block extension and mandatory e-filing work is explained in The Hong Kong Profits Tax Return in 2026: BIR51, BIR52 and BIR54, Block Extension and Mandatory E-Filing.

The fifth difference is tax residence and double taxation agreements. Under section 50AAC of Cap. 112, a company is resident for tax purposes in Hong Kong if it is incorporated in Hong Kong or, if incorporated outside Hong Kong, is normally managed or controlled in Hong Kong. A subsidiary is resident by virtue of incorporation and can obtain a Certificate of Resident Status (Forms IR1313A/B; the IRD’s target is 21 working days — conditions). A branch does not, as a rule, obtain a certificate: if management and control remain abroad, the company remains a resident of its home country, and Hong Kong’s double taxation agreements apply to it not as a Hong Kong resident but as a resident of the partner jurisdiction with a permanent establishment in Hong Kong. The exception is a foreign company that is normally managed or controlled from Hong Kong: it may apply for the certificate on the general basis, but its tax residence in the place of incorporation then needs a separate review. The criteria and procedure are covered in Hong Kong Certificate of Resident Status 2026: IRD Criteria, the Application Process and Claiming Benefits under the Mainland China CDTA.

The sixth is repatriation of profits. Hong Kong withholds no tax at source either on a subsidiary’s dividends or on a branch’s remittance of profits to head office (per the PwC summary, last reviewed 22 July 2026, there is no withholding tax on dividends and interest in Hong Kong), so there is no difference on the Hong Kong side. The exception is royalties: payments to the foreign parent for the use in Hong Kong of trademarks, software or other intellectual property are deemed Hong Kong income of the non-resident, and the payer withholds tax at an effective rate of 4.95% (2.475% on the first HK$6.67 million of gross royalties where the two-tiered rates apply; 16.5% between associates where the IP was previously owned by a Hong Kong taxpayer) — this applies to a subsidiary and a permanent establishment alike. The difference arises in the parent’s home country: a branch’s profits are, as a rule, included in the parent’s tax base in the current period with a credit for Hong Kong tax under domestic rules or a treaty, while a subsidiary’s dividends are taxed (or exempted) under the rules on dividends and controlled foreign companies. According to the IRD’s list, Hong Kong has comprehensive double taxation agreements in force with Russia (signed 18 January 2016, effective from the 2017/18 year of assessment), the UAE (11 December 2014, from 2016/17) and Belarus (16 January 2017, from 2018/19); an agreement with Kyrgyzstan was signed on 2 March 2026 and is not yet in force, and there is none with Kazakhstan — a Kazakh group would have to credit the branch’s Hong Kong tax under its domestic law. This is the part of the analysis that cannot be done without a tax adviser in the parent’s country.

The seventh is the territorial source principle and offshore profits. It is equally available to both structures: profits from active business sourced outside Hong Kong are not taxed, but this has to be proved transaction by transaction. For a group’s passive income there is a caveat — the FSIE regime (sections 15H–15R of Cap. 112, introduced by the Inland Revenue (Amendment) (Taxation on Specified Foreign-sourced Income) Ordinance 2022 with effect from 1 January 2023 and extended to gains on the disposal of any property from 1 January 2024): under the IRD’s guidance, foreign-sourced dividends, interest, IP income and disposal gains received in Hong Kong by an “MNE entity” — an entity that is a member of a group with a presence in more than one jurisdiction, with no revenue threshold whatsoever — are deemed Hong Kong-sourced and taxable unless the economic substance requirement, the participation requirement (5% for 12 months for dividends and equity disposal gains) or the nexus requirement for IP is met. Both a foreign group’s subsidiary and a foreign company with a permanent establishment in Hong Kong fall within the definition of an MNE entity, so passive income can no longer be routed through a Hong Kong structure without substance. How the territorial principle works in practice is described in Territorial Taxation and Offshore Status in Hong Kong 2026: A Complete Breakdown of How It Actually Works. Finally, for groups with consolidated revenue of EUR 750 million or more, the global minimum tax and Hong Kong’s top-up tax (HKMTT) under Ordinance No. 21 of 2025 apply to fiscal years beginning on or after 1 January 2025 — a permanent establishment in Hong Kong is a separate constituent entity of the group for those rules, on the same footing as a subsidiary; the scope and reporting are described in The Global Minimum Tax and HKMTT in Hong Kong in 2026: Scope, the IRD Portal and Form IR1485.

Liability and asset protection: a single legal person versus limited liability

Limited liability is the principle under which a company’s members are liable for its debts only up to the amount unpaid on their shares. A subsidiary gives its parent that shield; a branch does not, because the branch is the parent. This is the principal non-tax argument for a subsidiary, and it needs to be weighed in both directions.

On one hand, every contract, tort, employment dispute or regulatory fine of a Hong Kong branch is a claim against the foreign company, enforceable against its assets worldwide (subject to the rules on recognition of judgments). On the other hand, the parent’s financial difficulties automatically reach the branch: under section 793 of Cap. 622 the branch must notify the Registrar within 15 days of the commencement of the parent’s liquidation, and under section 795 the authorized representative must notify its dissolution, after which the company ceases to be a registered non-Hong Kong company (section 795(3)). Hong Kong counterparties and banks are aware of this and frequently assess a branch by the credit quality of the parent rather than of the Hong Kong business.

The flip side of the shield is that the separation of liability is not absolute. The subsidiary’s directors bear personal statutory duties and liabilities; a parent that gives instructions to the directors risks being a “shadow director” (section 2(1) of Cap. 622 defines it as a person in accordance with whose directions the directors are accustomed to act); and banks lending to a subsidiary almost always require a parent guarantee. For a group that guarantees all of its subsidiary’s obligations anyway, the difference in liability therefore shrinks in practice — while the difference in compliance remains.

For regulated activities the question of liability intertwines with licensing: SFC, HKMA and other regulators’ licences are issued to a specific person, and requirements as to capital, local management and substance may allow both forms (the HKMA, for example, authorises both branches of foreign banks and locally incorporated subsidiary banks) or require a local legal entity. That is decided not by the Companies Ordinance but by the sectoral statute.

Business registration, bank accounts, visas and staff: the practical differences

Business registration is the duty of every person carrying on business in Hong Kong to obtain a certificate from the Business Registration Office under the Business Registration Ordinance (Cap. 310). For both a branch and a subsidiary it is discharged through a one-stop arrangement: the NN1 or NNC1 application is deemed to be a simultaneous application for business registration, and the Registrar of Companies issues the business registration certificate on behalf of the Commissioner of Inland Revenue. The 2026/27 rates are identical: HK$2,350 for one year or HK$6,170 for three years. A separate “branch registration certificate” at HK$230 a year is not the “registration of a foreign company’s branch” but a certificate for an additional place at which the same business is carried on (a second office, warehouse or shop), and both structures need one if they operate from more than one address. The fee, the levy and the exemptions are covered in The Business Registration Ordinance (Cap. 310) in 2026: fee, levy, exemptions and branches. Non-compliance with Cap. 310 carries a fine of up to HK$5,000 and imprisonment for up to 1 year; the certificate must be displayed in a conspicuous place at every address.

A bank account for a branch is opened in the name of the foreign company with reference to its Hong Kong registration; the bank runs KYC not only on the Hong Kong business but on the parent’s entire structure, its beneficial owners and its country of incorporation. For a subsidiary the bank checks the subsidiary itself plus the parent as shareholder and the beneficial owners. In practice, banks more often ask a branch for the full set of the parent’s documents with legalisation, and a subsidiary for Hong Kong documents plus the ownership structure; where the parent’s country of incorporation is “difficult”, a separate Hong Kong entity often clears the checks more easily, although a subsidiary with a foreign shareholder still counts as “non-resident” for the bank. The options are analysed in Corporate Bank Accounts in Hong Kong for Non-Residents 2026: Traditional Banks, Virtual Banks, and Fintech.

Employment visas under the General Employment Policy are sponsored by the employer. The Immigration Department’s published requirements call for the employer’s business registration certificate, proof of financial standing (audited financial reports, profit and loss accounts or tax returns), a description of the business and — for companies established less than 12 months ago — a business plan showing funding sources and the creation of local jobs; there is no requirement that the sponsor be a locally incorporated company. The practical difference is which “financial standing” documents to show: for a branch, usually the parent’s accounts; for a new subsidiary, a business plan and capitalisation. Visa routes for staff and owners are described in Hong Kong Work and Relocation Visas 2026: GEP, the Top Talent Pass, the Entrepreneur Route, Dependants and Permanent Residence After Seven Years.

Staff are regulated identically for both structures: the Employment Ordinance, MPF, the Employer’s Return and employees’ compensation insurance — with the employer being either the foreign company (through the branch) or the subsidiary. Employer obligations are covered in Payroll and Employer Obligations in Hong Kong 2026: the Employment Ordinance, the Employer’s Return (BIR56A/IR56B) and Salaries Tax and The MPF in Hong Kong: Employer Obligations, Deadlines and Penalties in 2026.

Financing and charges: what changes for banks and creditors

A charge is a mortgage or other security created by a company over its property; under Part 8 of Cap. 622, “specified charges” must be registered with the Companies Registry within one month, failing which the security is void against a liquidator and creditors. According to the Companies Registry’s guidance, Part 8 applies to registered non-Hong Kong companies in respect of charges created over property in Hong Kong: a certified copy of the instrument is delivered with Form NM1 (fee HK$340), and the Registry states expressly that it will not accept charges created by non-Hong Kong companies that have not registered under Part 16. For a bank this means that security from an unregistered foreign company cannot be registered with the Companies Registry, so lenders as a rule require Part 16 registration before advancing funds — one more reason to register on time.

The difference between the structures here lies in the security package and the contracting party. With a branch, the borrower is the foreign company itself, and the Hong Kong bank analyses its consolidated accounts and jurisdiction; the security may include assets abroad, but their enforcement is governed by foreign law. With a subsidiary, the borrower is a Hong Kong entity with its own balance sheet, and the bank almost always requires a corporate guarantee from the parent; registration of a charge over the subsidiary’s assets follows the same Part 8 rules and the same HK$340 fee.

In its annual return NN3 a branch must show the total indebtedness in respect of all registered charges (section 9(1)(m) of Cap. 622J) — public information available to any counterparty for HK$16–18 through e-Search. A subsidiary discloses its charges in the NAR1 in the same way. Capital, however, is disclosed differently: a branch states in the NN3 the authorized and issued capital of the whole parent company (section 9(1)(l)), while a subsidiary states its own issued capital; the statute sets no minimum capital for either structure.

Comparing the four formats of presence: branch, subsidiary, representative office and re-domiciliation

A comparison of the formats of presence sets side by side the four lawful ways for a company incorporated abroad to operate in Hong Kong: registering a branch under Part 16, incorporating a subsidiary under Part 3, a representative office registered only with the Business Registration Office, and moving the company itself to Hong Kong under Part 17A. The table below summarises the statutory differences; the figures are as at September 2026.

Cost and timing: what a business actually pays for a branch and for a subsidiary

The cost of presence is made up of government fees, which are identical or nearly so, and compliance costs, which differ by a multiple. Below are only the government fees at current rates; provider, auditor and lawyer fees depend on the scope of work and are not included.

Total first-year government fees on electronic filing are HK$3,895 for either structure (HK$1,545 registration plus a HK$2,350 one-year business registration certificate); from the second year a branch pays HK$2,530 a year (HK$2,350 + HK$180) and a subsidiary HK$2,455 (HK$2,350 + HK$105). The HK$75-a-year difference in fees is negligible. The real difference is that a subsidiary pays for an annual audit, a company secretary, a registered office and SCR maintenance, while a branch pays for certified copies and translations of the parent’s documents every time the constitution or the board changes, and for the authorized representative’s services. UPPERSETUP provides bookkeeping for both structures — including the branch accounts for the IRD and the auditable financial statements of a subsidiary — as part of its Accounting Support for Companies service.

Re-domiciliation: the third route since 23 May 2025

Re-domiciliation is the transfer of a company incorporated abroad to Hong Kong with its legal personality preserved: since 23 May 2025, under Part 17A of Cap. 622 (introduced by the Companies (Amendment) (No. 2) Ordinance 2025), such a company is registered as a “re-domiciled company” and, under section 2(5A), is regarded for the purposes of Hong Kong law as incorporated in Hong Kong from the re-domiciliation date. For a branch this is a direct alternative: according to the Companies Registry’s FAQ, a company registered under Part 16 may apply to re-domicile, and its Part 16 registration ceases to have effect upon re-domiciliation; the existing business registration number is retained.

The conditions: the company must correspond to one of the four types of Hong Kong company with a share capital; its first financial year in the place of incorporation must have ended as at the application date; the members must consent under the law of the place of incorporation; the board certifies that the creditors have been notified; there is no economic substance test. The fee is HK$6,050 on electronic filing (HK$1,030 lodgment plus HK$5,020 registration) and HK$6,725 on paper; processing takes about two weeks if the documents are complete. After re-domiciliation the company must deregister in its former jurisdiction within 120 days (a period the Registrar may extend on such conditions as it considers appropriate) and provide evidence, failing which the Registrar may revoke the registration under section 820F — and the company, if it retains a place of business, must then re-register as a branch within one month (section 776(1)(c), (3A)).

According to the Companies Registry, 70 re-domiciliation applications had been received by 30 June 2026 and 42 companies had successfully re-domiciled. The regime suits groups that want both the limited liability of a local company and the continuity of contracts, licences and corporate history without transferring assets; it does not suit companies whose jurisdiction does not permit an “exit”, or companies younger than one financial year. The full breakdown of conditions, documents and tax consequences is in Company Re-domiciliation to Hong Kong in 2026: The Complete Part 17A Breakdown — Eligibility, Documents, Timelines and Tax.

How to close a branch and how to close a subsidiary: 7 days versus deregistration under section 750

Closing a branch is not a liquidation (there is nothing to liquidate: the legal person continues to exist abroad) but a notice that the company has ceased to have a place of business in Hong Kong. Under section 794 of Cap. 622 the notice on Form NN13 is delivered within 7 days after the cessation; the Registrar enters a statement in the register, and from that moment the company is no longer a registered non-Hong Kong company. Late delivery is a level 3 fine (HK$10,000) plus HK$300 a day. In parallel, the Business Registration Office is notified within one month, the tax affairs are closed (final BIR51, Employer’s Return, MPF) and contracts are terminated. No fee is charged for the NN13.

If a branch is simply abandoned, the Registrar can act of its own motion: where it has reasonable cause to believe that the place of business has ceased, send an inquiry letter to the authorized representative or, if no representative is shown in the register, to the place of business (section 796), and if there is no reply within a month, or the reply confirms cessation, the Registrar must send a second letter and publish a notice in the Gazette (section 797) — or, if a letter is unlikely to be received, publish the notice straight away (section 796(3)); 3 months after publication the company may be struck off the register (section 798). After striking off, the company may not have a place of business in Hong Kong unless it applies for registration afresh within one month of establishing a new one (section 798(4)–(5)); restoration is available on the application of a director or member within 6 years, but only if the company had a place of business in Hong Kong at the time of the application and at some time within the 6 months before it was struck off (sections 799–801). The accumulated penalties for undelivered NN3s do not disappear.

Closing a subsidiary means either deregistration under section 750 of Cap. 622 or winding up under the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32). Deregistration is available only if all members agree, the company has not carried on business in the previous 3 months, has no outstanding liabilities, is not a party to legal proceedings and holds no Hong Kong immovable property (directly or through subsidiaries); the application is accompanied by a HK$420 fee and a Notice of No Objection from the Commissioner of Inland Revenue, for which the IRD charges a non-refundable HK$270 and which it issues within 21 working days if there are no outstanding taxes, unfiled returns or open enquiries (IRD conditions). The process as a whole takes several months with Gazette publications; winding up takes longer and costs more. Details are in Closing a Hong Kong Company in 2026: Deregistration, Winding Up and the IRD Notice of No Objection.

The difference is fundamental for a “test the market” strategy: a branch’s exit is recorded by a Form NN13 notice within 7 days of closing the office (the foreign company’s Hong Kong tax liabilities for the period of operation survive), a subsidiary’s only through deregistration with IRD clearance or a winding up. On the other hand, selling a subsidiary’s business means selling its shares (stamp duty of 0.1% per side on the value of the shares or of the net assets, rate since 17 November 2023), while selling a branch’s business means transferring assets and contracts one by one, with stamp duty only on any Hong Kong stock and immovable property among them. The valuation rules and deadlines are in Stamp Duty on Share Transfers in Hong Kong 2026: Rates, Net-Asset Valuation, Deadlines and Penalties. Intra-group share transfers between companies with a 90% association are relieved under section 45 of the Stamp Duty Ordinance; the 2026/27 Budget proposed lowering the threshold to 75% with retrospective effect from 25 February 2026, but according to PwC as at 30 June 2026 the bill is planned for introduction into the Legislative Council only in October 2026, and until it is enacted the 90% threshold applies — the status of the bill should be re-checked before any transaction.

Step-by-step: how to choose the structure and register it without missing a deadline

The structure selection process is a sequence of checks that settles the “branch or subsidiary” question before an office appears in Hong Kong and the one-month clock under section 776 starts running. The order matters: the tax analysis in the parent’s home country should come before the Hong Kong analysis, because it is most often the decisive one.

1.       Decide whether there will be a place of business in Hong Kong. If the plan is only sales from abroad, an independent distributor or space rented from a logistics operator without staff, Part 16 registration is not required, although business registration may still be needed where other indicia of carrying on business in Hong Kong exist. If there will be an office, employees or a showroom, proceed to step 2 and fix the planned opening date.

2.       Check whether income in Hong Kong is needed at all. If the office will only liaise between the parent and customers and gather information, without contracts or revenue, a representative office registered with the Business Registration Office is enough, and the IRD will normally exempt it from further returns. Any contract with a Hong Kong customer or any invoice issued from Hong Kong means that a place of business has been established and starts the one-month registration period under section 776.

3.       Assess tax in the parent’s home country. Ask a local adviser how the profits of a foreign permanent establishment are taxed (credit, exemption, inclusion), whether there is a treaty with Hong Kong (Russia and the UAE have one, Kazakhstan does not), how a subsidiary’s dividends are taxed and whether controlled foreign company rules apply. If branch profits are included in the current year’s base while a subsidiary’s dividends are exempt, that argues for a subsidiary; if start-up losses are expected that can be relieved at home, that argues for a branch.

4.       Assess liability and regulatory requirements. If the activity carries significant contractual or tort risk and the group is not prepared to answer with all its assets — a subsidiary. If the activity is licensable — check with the regulator which form is permitted.

5.       Cost the compliance. Subsidiary: annual audit, company secretary, registered office, SCR, NAR1, BIR51 with audited financial statements. Branch: NN3 with the parent’s accounts (if published), authorized representative, certified copies and translations at every change, BIR51 with branch accounts and the four items of information instead of an audit, attribution of profits under section 50AAK.

6.       Check the name. If the company’s domestic name is in Cyrillic or Arabic script, prepare in advance a certified English translation and a certified translation of the relevant part of the certificate of incorporation; check the Index of Company Names to make sure the translated name does not coincide with an existing one, so as not to receive a section 780 notice.

7.       Appoint an authorized representative of one of the five types in section 774(1) and document the consent; make sure the representative has a Hong Kong address and an identity card or passport.

8.       Assemble the documents abroad: certified copies of the constitution and the certificate of incorporation (and of the change-of-domicile document, if any), the latest published accounts or a statement that there are none, and — not as a Cap. 622J requirement but for the bank and the representative — the resolution of the governing body establishing the place of business and appointing the representative. Certification under section 775: a notary, lawyer, accountant, government official, court officer or company secretary in the place of incorporation, or an officer of the company.

9.       File the NN1 with the IRBR2 through the e-Services Portal within one month of establishing the place of business; pay HK$1,545 and HK$2,350 (or HK$6,170 for three years); receive the PDF certificate within about 9–10 working days and download it — it is available for six months.

10.    Display the name, place of incorporation and limited-liability statement at the office and in all documents under Cap. 622M; display the business registration certificate.

11.    Put in the calendar: anniversary of the certificate + 42 days (NN3, HK$180); 1 month for NN5–NN10 after any change; 7 days for NN13 on closure; 15 days for notices of the parent’s liquidation or dissolution; the BIR51, Employer’s Return and MPF deadlines.

12.    Review the structure after a year. If the business has grown, or local partners, creditors or plans to sell have appeared, consider converting to a subsidiary (asset transfer) or re-domiciling (preservation of the legal person, HK$6,050, about two weeks, first financial year must have ended).

If you need help choosing the format and running the full registration cycle — from preparing the parent’s documents and appointing the authorized representative to opening the account and tax registration — UPPERSETUP handles both options; see the Catalog of company registration solutions.

Common mistakes in choosing between a branch and a subsidiary, and what they cost

A typical mistake here is a decision taken on a single criterion (usually “which is cheaper to open”) without regard to the fact that the differences show up not at registration but in the annual cycle, in the parent’s home-country tax and on exit. Below are the most frequent mistakes and their statutory price.

1.       Assuming that an office is “not yet a branch”. The company rents an office, hires a manager and negotiates, but postpones registration “until the first contract”. The section 776 period runs from the date the place of business is established; Form NN1 requires that date to be stated, and the Registrar sees the delay. The price: a level 5 fine (HK$50,000) plus HK$1,000 a day for the company, its responsible persons and agents, plus refusal to register charges until Part 16 registration is complete.

2.       Appointing “any corporate services company” as the representative. Only a resident natural person, a solicitor corporation, a corporate practice, a firm of solicitors or a CPA firm may act (section 774(1)). An application with an ineligible representative will not go through, and the departure of the only representative without a replacement within a month is a separate offence under section 786 at the same level 5.

3.       Filing a Cyrillic name without a certified translation. Section 776(5) requires the translation, and section 7 of Cap. 622J also requires a translation of the relevant part of the certificate of incorporation. Registration stalls, and the one-month period is not suspended.

4.       Forgetting that the anniversary runs from the Hong Kong registration. The NN3 is delivered within 42 days after the anniversary of the certificate, not after the parent’s financial year end. Late delivery means a fee of up to HK$4,800 instead of HK$180 and level 5 criminal liability; the Registrar does not extend the deadline.

5.       Attaching unaudited branch accounts to the NN3 — or nothing at all. Under section 789 the return is accompanied by the published accounts of the whole company, and only if their publication is compulsory in the place of incorporation or under stock exchange rules; if it is not, the Section 12B box must be ticked rather than left blank. Failing to deliver accounts that are required is a level 5 fine plus HK$1,000 a day under section 789(3); superfluous branch accounts carry no fine but may lead to rejection of the NN3 and lateness under section 788.

6.       Electing the two-tiered rates for both the branch and the subsidiary. The parent and its subsidiary are connected entities, and only one of them gets the 8.25% rate on the first HK$2,000,000. A double election means additional assessments and a penalty for an incorrect return.

7.       Not attributing profits to the permanent establishment under section 50AAK. A branch that reports a “convenient” share of group profits in its BIR51 without a functional analysis risks an assessor’s estimate: the assessor may determine the arm’s length amount and raise an additional assessment (section 50AAK(9)–(10)).

8.       Counting on a Hong Kong Certificate of Resident Status for a branch. A company incorporated abroad is Hong Kong resident only if it is normally managed or controlled in Hong Kong (section 50AAC of Cap. 112); a typical branch does not meet that test, and double taxation agreements apply to the parent as a resident of its own country.

9.       Overlooking Cap. 622M. Invoices and contracts of a branch that omit the place of incorporation and the limited-liability statement mean a level 3 fine (HK$10,000) for the company, every responsible person and every agent; it is the most common finding when a branch’s documents are reviewed.

10.    Closing the office without filing the NN13. The deadline is 7 days (section 794), not a month; after it the Registrar may start the striking-off procedure under sections 796–798, while undelivered NN3s keep accumulating fees and penalties.

11.    Choosing a subsidiary “for protection” and immediately guaranteeing all of its obligations to the bank. Limited liability then stops working where it matters most — against the creditor — while the annual audit, the secretary and the SCR remain.

12.    Not checking the parent’s home-country tax. In many jurisdictions branch profits are included in the current year’s base; for a Kazakh group with no treaty with Hong Kong, the credit for Hong Kong tax depends on domestic law. A subsidiary can defer tax until dividends are paid but triggers controlled foreign company rules. Without this analysis, choosing a structure is guesswork.

Who a branch suits, who a subsidiary suits, and when a professional review is needed

A branch suits a company that wants to test the Hong Kong market quickly and reversibly; a group whose home rules allow the start-up losses of the Hong Kong unit to be relieved; a foreign bank or financial institution for which the regulator permits or requires the branch form; a company with published and audited accounts that does not want to pay for a second audit; a business that creates no significant contractual or tort exposure (consulting, representative functions with contracting authority, sourcing). The arguments in favour: registration without any merits assessment by the Registrar, no audit under Cap. 622 or for the IRD, no company secretary or SCR, exit by a Form NN13 notice within 7 days of closing the office.

A subsidiary suits a business with real operating risks (trading, manufacturing, services with liability to customers, a sizeable workforce); a group planning to bring in local partners or investors or to sell the business (a share sale with stamp duty of 0.1% per side is simpler than an asset transfer); a company that needs a Hong Kong Certificate of Resident Status and access to Hong Kong’s double taxation agreements; a parent in a jurisdiction where dividends are exempt but permanent-establishment profits are not; a group for which a separate legal entity simplifies bank compliance. The arguments in favour: limited liability, a separate tax personality, the reputation of a “Hong Kong company”, a sale through shares without transferring assets — although the two-tiered rates still go to only one connected entity in the group.

Re-domiciliation suits an existing company older than one financial year that wants both to become a Hong Kong legal person and to keep its contracts, licences and history without transferring assets — provided the jurisdiction of incorporation permits an exit and the company is ready to deregister there within 120 days (or such longer period as the Registrar allows).

A professional review is essential if: it is unclear whether the planned presence constitutes a place of business; the activity is licensed by the SFC, HKMA, Insurance Authority or another regulator; the parent is incorporated in a country with no treaty with Hong Kong or with strict permanent-establishment rules; intra-group transactions requiring Part 8AA analysis are expected; the group is approaching the EUR 750 million threshold for the global minimum tax; the company has several domestic names or names not in Latin characters; a later sale or investor entry is planned. Legal analysis of the structure, preparation of the governing body’s resolutions and support on regulatory questions are part of UPPERSETUP’s legal services.

FAQ: branch and subsidiary in Hong Kong

How does a branch of a foreign company in Hong Kong differ from a subsidiary?

A branch (a registered non-Hong Kong company) is the foreign company itself, registered under Part 16 of the Companies Ordinance (Cap. 622) after establishing a place of business in Hong Kong; no new legal person arises, and the parent is liable for all obligations. A subsidiary is a separate Hong Kong legal entity under Part 3 of the same Ordinance with limited shareholder liability. The profits tax rate is the same (16.5%; the two-tiered regime gives 8.25% on the first HK$2,000,000), while liability, the volume of compliance (audit, company secretary and SCR apply only to a subsidiary) and the tax consequences in the parent’s home country differ.

Does a foreign company have to register a branch if it has only one employee in a rented office in Hong Kong?

Yes, if the office is a place of business of the company. Section 776 of Cap. 622 requires an application for registration within one month of establishing a place of business, and the statute sets no minimum headcount or turnover. The only express exclusion is a local representative office of a bank established with the Monetary Authority’s approval (section 774(3)). The penalty for non-compliance is a level 5 fine (HK$50,000) plus HK$1,000 a day.

How much does branch registration in Hong Kong cost and how long does it take in 2026?

The Companies Registry fee is HK$1,545 on electronic filing (HK$1,280 plus a non-refundable HK$265 lodgment fee) or HK$1,720 on paper; the business registration fee and levy are paid on top — HK$2,350 for one year (for certificates commencing between 1 April 2026 and 31 March 2027) or HK$6,170 for three years. The certificate is normally issued within 9–10 working days (the Companies Registry’s benchmarks) as a PDF. Most of the time is spent preparing certified copies and translations of the parent’s documents.

Does a branch of a foreign company in Hong Kong need an audit?

Under the Companies Ordinance — no: section 789 only requires a certified copy of the whole company’s already published accounts to accompany the annual return NN3, and only if their publication is compulsory under the law of the place of incorporation or stock exchange rules. For tax purposes the IRD accepts unaudited accounts from a Hong Kong branch provided that four items accompany the BIR51: the place of incorporation, whether that country’s law requires a statutory audit of the world-wide financial statements, whether that audit has been conducted, and a brief summary of the branch’s accounting records. A subsidiary, by contrast, must be audited every year under section 405 of Cap. 622 and must attach audited financial statements to its BIR51.

Who can be the authorized representative of a branch in Hong Kong?

Only five categories under section 774(1) of Cap. 622: a natural person resident in Hong Kong; a solicitor corporation; a corporate practice under Cap. 588; a firm of solicitors; or a CPA firm under Cap. 588. The representative accepts service of process and notices on the company’s behalf; if the only representative ceases to act, the company must register a replacement within one month (section 786), and a termination takes effect no earlier than 21 days after the Registrar is notified (section 787).

Can a branch obtain a Hong Kong Certificate of Resident Status?

As a rule, no. Under section 50AAC of the Inland Revenue Ordinance, a company incorporated outside Hong Kong is Hong Kong resident only if it is normally managed or controlled in Hong Kong; a typical branch is managed from the parent’s home country, so the company remains resident there, and Hong Kong’s double taxation agreements apply to it as a foreign resident with a permanent establishment in Hong Kong. A subsidiary is resident by incorporation and may apply for a Certificate of Resident Status (Forms IR1313A/B; target 21 working days).

How do you close a branch of a foreign company in Hong Kong?

Deliver a notice on Form NN13 to the Companies Registry within 7 days after the place of business ceases (section 794 of Cap. 622; no fee), notify the Business Registration Office within one month, file the final BIR51 and Employer’s Return, and close the MPF scheme and contracts. Once the statement is entered, the company is no longer a registered non-Hong Kong company. A subsidiary cannot be closed this way: it requires deregistration under section 750 (HK$420 fee plus an IRD Notice of No Objection at HK$270) or a winding up.

Does a branch keep a significant controllers register (SCR)?

No. The duty to keep an SCR under Division 2A of Part 12 of Cap. 622 falls on an “applicable company”, and “company” in section 2(1) covers only companies formed under Cap. 622, “existing companies” and re-domiciled companies. A branch is not a company and therefore keeps no SCR; a subsidiary has had to keep the register since 1 March 2018.

Can a branch be turned into a Hong Kong company without transferring assets?

Yes, since 23 May 2025 — through re-domiciliation under Part 17A of Cap. 622. A company registered under Part 16 may apply; on registration its branch status ceases, and the company is regarded as incorporated in Hong Kong from the re-domiciliation date. The conditions: correspondence to one of the four Hong Kong company types, the end of the first financial year in the place of incorporation, members’ consent and notification of creditors; the fee is HK$6,050 (electronic), processing takes about two weeks, and deregistration in the former jurisdiction must follow within 120 days (extendable).

Key takeaways

A branch and a subsidiary in Hong Kong pay the same profits tax and the same government fees (HK$1,545 for registration, HK$2,350 for the annual business registration certificate), but they are different legal constructions: a branch is the same foreign company with full liability, registered under Part 16 of Cap. 622 within one month of establishing a place of business; a subsidiary is a separate entity with limited liability, a company secretary, a natural-person director, an annual audit and a significant controllers register.

A branch’s annual cycle is shorter and cheaper: NN3 within 42 days after the anniversary of registration (HK$180), the parent’s accounts only if they are published at home, notifications of changes within a month, branch accounts for the IRD without an audit if four items of information are supplied; but a branch’s profits are attributed to the permanent establishment under section 50AAK of Cap. 112, a Certificate of Resident Status is, as a rule, unavailable, and the name, the place of incorporation and the limited-liability statement are mandatory on invoices and contracts under Cap. 622M.

The choice is determined not by Hong Kong fees but by three questions: is the group prepared to answer with all its assets; how are permanent-establishment profits and subsidiary dividends taxed in the parent’s home country (Russia and the UAE have a treaty with Hong Kong, Kazakhstan does not); and is an exit through a share sale needed, or is a 7-day NN13 notice enough. Since 23 May 2025 there is a third route — re-domiciliation for HK$6,050, which turns the foreign company itself into a Hong Kong one.

Summary

A branch of a foreign company in Hong Kong (a registered non-Hong Kong company) is registered under Part 16 of the Companies Ordinance (Cap. 622) within one month of establishing a place of business (section 776; level 5 fine of HK$50,000 plus HK$1,000 a day): Form NN1, certified copies of the constitution, certificate of incorporation and published accounts, an authorized representative in Hong Kong of one of the five types in section 774(1), a fee of HK$1,545 on electronic filing plus a business registration fee of HK$2,350 for one year (2026/27 rate), and a certificate in about 9–10 working days. A branch is not a separate legal person: the parent is liable for its obligations. Annually: NN3 within 42 days after the anniversary of registration (HK$180; late up to HK$4,800 and criminal liability), notifications of changes within a month, NN13 within 7 days on closure; no audit under Cap. 622, no SCR, and disclosure of the name and place of incorporation under Cap. 622M. A subsidiary (a private company limited by shares under Part 3 of Cap. 622) is a separate entity with limited liability: the same fees, a certificate in about 1 hour, but a natural-person director, a resident company secretary, a registered office, an annual audit, NAR1 (HK$105) and an SCR are mandatory. Profits tax is identical (16.5%; 8.25% on the first HK$2,000,000 for only one connected entity), but a branch’s profits are determined under section 50AAK of Cap. 112 as those of a separate enterprise, the IRD accepts unaudited branch accounts with four items of information, and a Hong Kong Certificate of Resident Status is, as a rule, unavailable to a branch. Since 23 May 2025 re-domiciliation is available (HK$6,050, about two weeks), which terminates branch status. Current as at September 2026.
