Can an overseas auditor audit financial statements for UAE corporate tax?

Article 54 of the Corporate Tax Law lets the Minister require certain Taxable Persons to prepare and maintain audited financial statements. The FTA's summary of private clarifications issued up to May 2026 includes this question: can the audit requirement be met by an overseas auditor?

The FTA says no. Where the law requires audited financial statements, the auditor must be:

• a UAE auditor registered with the UAE Ministry of Economy; and
• a Chartered Accountant or accounting firm practising an auditing or accounting profession within the UAE.

The audit profession in the UAE is regulated under Federal Decree-Law No. 41 of 2023 concerning the Regulation of the Accounting and Auditing Profession, overseen by the Ministry of Economy (now the Ministry of Economy and Tourism). A partner in a group audit firm's London or Mumbai office may audit the consolidated accounts, but cannot sign the UAE entity's audit report for corporate tax purposes unless they meet these UAE conditions. In practice, groups use the UAE member firm of their network.

Ministerial Decision No. 84 of 2025 applies to Tax Periods starting on or after 1 January 2025. It replaced Ministerial Decision No. 82 of 2023, which still governs earlier periods. Under Article 2, the following must prepare and maintain audited financial statements:

• a Taxable Person that is not a Tax Group and has revenue above AED 50,000,000 in the Tax Period;
• every Qualifying Free Zone Person, whatever its revenue; and
• a Tax Group, which prepares audited special purpose financial statements in the form and under the rules the FTA sets.

A qualifying free zone person distributing goods in or from a Designated Zone must also follow additional FTA procedures. FTA Decision No. 6 of 2026 introduced an agreed-upon procedures report for this. For a non-resident, only revenue earned through its UAE permanent establishment or nexus counts toward the AED 50 million (Article 2(4)).

Separately, the Commercial Companies Law requires an annual audit for LLCs and joint stock companies, whatever their revenue.

The same FTA summary covers a related question: for an investment business, is the AED 50 million audit threshold measured on gross or net revenue?

The FTA says the threshold follows IFRS and is based on the revenue in the financial statements. For trading in securities and investments, it is the total gains on sales, worked out under IFRS 9 as gross proceeds less the cost of the investments sold, where proceeds exceed cost. Losses are disregarded because they are not income in the profit and loss account.

So an investment company that sells AED 400 million of securities with a cost of AED 370 million has AED 30 million of gains counting toward the threshold, not AED 400 million. A separate AED 25 million of losses on other disposals does not reduce that AED 30 million. Add other revenue such as dividends or fees as recognised under IFRS, and test the total against AED 50 million.

• Use a UAE-registered auditor for the UAE entity. Group instructions to the network's UAE firm can align the local audit with the group timetable.
• Statutory and tax audits can be one engagement. A single UAE audit of IFRS statements can meet both the Commercial Companies Law and corporate tax requirements, provided the auditor is UAE-registered.
• Free zone rules may be narrower. Some free zone authorities keep their own approved auditor lists. A free zone company may need an auditor that is both MoE-registered and approved by its free zone.
• Plan for tax groups. Special purpose aggregated statements for a Tax Group are a separate deliverable from each member's statutory accounts.
• Keep the audit report with the return records. Audited statements are part of the records the FTA can request.

A private clarification is addressed to the applicant, so the summary shows the FTA's approach rather than a binding ruling for everyone. The answer follows the UAE audit licensing regime, and few taxpayers would want to test it.

Before signing an audit engagement for a UAE entity that needs audited statements for corporate tax, confirm:

1. Registration: the signing firm and the engagement partner are registered with the Ministry of Economy to practise auditing in the UAE. Ask for the registration details in the proposal.
2. Local practice: the firm practises in the UAE. A foreign network firm signing remotely does not meet the FTA's description.
3. Free zone approval: where the entity is licensed in a free zone with an approved auditor list, the firm is on that list.
4. Framework: the statements are prepared under IFRS, or IFRS for SMEs where revenue is AED 50 million or less. The FTA's summary also says statements under foreign accounting standards cannot be used to compute taxable income.
5. Timing: the audit will finish before the corporate tax return is due, nine months after the end of the Tax Period.

For a qualifying free zone person, audited financial statements are one of the conditions for the 0% rate. Statements audited by an auditor who does not meet the UAE requirements risk being treated as not audited for corporate tax. That could put qualifying status in doubt for the Tax Period. Losing qualifying status means 9% on taxable income above AED 375,000 for that period and the following four Tax Periods.

For a mainland company above AED 50 million, the risk is a failure to keep required records, an FTA request to provide properly audited statements, and possible administrative penalties for record-keeping breaches.

If an overseas firm has already signed this year's accounts, the fix is a UAE audit by a registered auditor before the corporate tax return is filed. Leaving it until an FTA review is far more expensive. Check the auditor's Ministry registration and, for free zone entities, the authority's approved list before signing the engagement letter.
