Mandatory audit in the UAE typically follows from three independent sources of obligation: Federal Decree-Law No. 32 of 2021 (Commercial Companies Law) for mainland companies, PJSCs, and PrJSCs; the internal rules of the specific free zone for licence renewal; and Ministerial Decision No. 84 of 2025 for Corporate Tax purposes. An audit is mandatory for Qualifying Free Zone Persons (regardless of revenue), for any taxable person with revenue exceeding AED 50 million in the tax period, for all Tax Groups, and for most companies in major free zones (DMCC, JAFZA, DIFC, ADGM, and others) — independently of the tax rules, as a condition of licence renewal.
