Audit & Assurance in the UAE

Almost every argument about whether a UAE company "needs an audit" comes from mixing up two rules that were written for different purposes and sit in different laws. The first is company law. Article 27(1) of Federal Decree-Law No. 32 of 2021, the Commercial Companies Law, states that every joint stock company or limited liability company shall have one or more auditors to audit the accounts of the company on a yearly basis, and that the remaining forms of companies may appoint an auditor in accordance with the Decree-Law. This obligation has nothing to do with tax. It attaches to the company form itself. The second is corporate tax. Article 54(2) of Federal Decree-Law No. 47 of 2022 lets the Minister determine which categories of taxable person must prepare and maintain audited financial statements, and Ministerial Decision No. 84 of 2025 sets those categories. This is a tax-filing obligation, tested against revenue and status rather than company form. A business can be caught by one, both, or, if it is a mainland sole establishment under the tax threshold, arguably neither. The two questions must be answered separately.

The Commercial Companies Law is more prescriptive than most summaries suggest, and the detail matters when a dispute arises about whether an audit was properly conducted. Article 27(2) requires every company to prepare annual financial accounts including the balance sheet and the profit and loss account. Article 27(3) requires the company to apply International Accounting Standards and Practices when preparing its periodical and annual accounts, so as to give a clear and accurate idea of the profits and losses. Article 27(4) gives every partner or shareholder the right, on written request, to a free copy of the last audited accounts and the last auditor's report, and a copy of the group accounts where the company is a holding company. The company must respond within ten days of the request. That right is often forgotten in shareholder disputes.

Article 248 sets out the duties, and reading it changes how a business should prepare for an audit.

The auditor audits the accounts, inspects the balance sheet and profit and loss account, reviews the transactions of the company with related parties, and verifies the application of the Decree-Law and the company's statute. The report goes to the general assembly, with a copy dispatched to the Authority and the competent authority.

In preparing the report the auditor must verify the validity of the accounting registers kept by the company and the consistency between the company's accounts and those registers. Article 248(3) gives the auditor the right to review all registers, papers and other documents, to require explanations, and to verify the assets, rights and obligations of the company.

Article 248(4) covers obstruction: if the auditor is not given facilities to perform the duties, that must be evidenced in a report to the board, and if the board fails to act, a copy goes to the Authority.

This decision replaced Ministerial Decision No. 82 of 2023 and reset who must produce audited financial statements for corporate tax purposes. Article 2(1) names two categories. A taxable person that is not a tax group and derives revenue exceeding AED 50,000,000 during the relevant tax period must prepare and maintain audited financial statements. So must a qualifying free zone person, with no revenue threshold attached: a QFZP earning modest revenue is still in. Article 2(2) deals with tax groups separately: a tax group shall prepare and maintain audited special purpose financial statements in accordance with the form, procedures and rules specified by the Authority. That is a different deliverable from an ordinary statutory audit, and the phrase "special purpose" is doing real work. Article 2(4) adds a rule for non-residents: in calculating the revenue threshold, only revenue derived through permanent establishments or nexuses in the State is taken into account.

For corporate tax the answer is unambiguous, and it does not move with size. Article 2(1)(b) of Ministerial Decision No. 84 of 2025 requires every qualifying free zone person to prepare and maintain audited financial statements, at any level of revenue. A free zone company that wants the 0% rate on qualifying income cannot skip the audit: audited statements are a condition of the status, not a consequence of turnover. Readers searching this as "is audit mandatory for freezone companies in the UAE" are usually asking a second and different question, does the zone itself demand one? No federal instrument answers that. Each free zone authority sets its own filing requirement as a condition of licence renewal, and several maintain a list of auditors whose reports they will accept. Two things can be said precisely rather than vaguely. First, DMCC is the zone whose approved-auditor list is genuinely published, as a client-rendered lookup on its own portal, which is why no count of it appears anywhere on this site.

Second, there is no federal, cross-zone auditor register to check a firm against: the Ministry of Economy and Tourism publishes application service cards for its practising-auditor registers, not a searchable directory. So "check the register" is useful advice only for the zones that actually publish one, and misleading everywhere else. We do not reproduce any zone's approved-auditor list here. Those lists change without notice, and a stale copy of one is worse than none.

Economic Substance Regulations obligations are still marketed as a recurring compliance service across the UAE advisory market, and for most businesses that is now out of date.

The Ministry of Finance announced the cancellation of economic substance reporting requirements for companies for financial years ending after 31 December 2022, under Cabinet Decision No. 98 of 2024, which amends Cabinet Decision No. 57 of 2020. The Ministry framed the change as aligning with the introduction of the federal corporate tax regime.

What has not gone away is history. The Ministry's announcement is explicit that companies remain responsible for fulfilling compliance obligations for prior years, and for any penalties imposed by the Federal Tax Authority. Notifications and reports for financial years ending on or before 31 December 2022, and any penalties arising from them, still stand.

If you are being quoted an annual fee for ESR filings covering a current financial year, ask which financial year the filing relates to before paying it.

A voluntary disclosure is the form a taxpayer files with the Federal Tax Authority to correct an error in a return, a tax assessment or a refund application already submitted, and filing one before the Authority notifies you of a tax audit is worth a fixed 15% of the tax at stake. It is not part of a statutory audit of your financial statements. The two collide only because both are called an audit. The arithmetic sits in the table annexed to Cabinet Decision No. 75 of 2023 for corporate tax, with the same structure mirrored in Cabinet Decision No. 40 of 2017 as amended for VAT and excise. Item 10 prices a voluntary disclosure at 1% per month of the tax difference. Item 11 applies where the person fails to submit one before being notified that they will be subject to a tax audit: a fixed 15% of the tax difference, on top of that same 1% per month.

The trigger is the notification, not the auditor's arrival. Because Article 16(2) of the Tax Procedures Law requires at least ten business days' notice of a tax audit, the 15% is already fixed by the time that notice reaches you. The ten days are notice of a penalty that has crystallised, not a window to avoid it.

External or statutory audit is an independent opinion on whether financial statements give a fair view, delivered to shareholders and required by law. Internal audit is a management function: an ongoing, in-house assessment of risk, controls and governance, reporting to the board or an audit committee rather than to the general assembly. The two are not substitutes, and the independence rules make that explicit. Article 246(3) of the Commercial Companies Law bars the statutory auditor from occupying a board seat or any technical, administrative or executive office in the company, which is precisely the office an internal auditor holds. One firm cannot be both. Internal audit is not a Commercial Companies Law obligation at all. A full-text search of the Ministry's English text of Federal Decree-Law No. 32 of 2021 returns no occurrence of "internal audit", "audit committee" or "internal control" (checked 17 August 2026). Where the duty exists it comes from Article 6(1) of that law, which lets the Minister issue governance decisions for companies other than public joint stock companies and the Securities and Commodities Authority board issue them for PJSCs, notwithstanding Central Bank requirements for the entities it licenses; Article 7 backs those decisions with fines of up to AED 10,000,000. Sector regulation and listing rules are therefore the place to look, not the company-law audit articles.

"How much does an audit cost in Dubai" is one of the most-searched questions in this topic and one of the least honestly answered. There is no published tariff. Audit fees are not regulated by the Ministry of Economy or by any free zone authority, and for public joint stock companies Article 245(3) of the Commercial Companies Law hands fee-setting to the general assembly on a case-by-case basis. Any page quoting you a firm range is quoting its own price list, or someone's guess. What we can tell you is what actually drives the number: transaction volume rather than revenue, the number of entities and whether consolidation is needed, the quality of the bookkeeping the auditor receives, whether related-party transactions require transfer pricing analysis, inventory and whether a physical count must be observed, the number of banks and currencies, and how much of the prior year the auditor has to re-perform if this is a first-year engagement. The cheapest quote is frequently the one that assumes clean books. If yours are not, the fee moves, and it moves after you have signed.

Most audit delays in practice come from the same handful of gaps, and all of them are fixable before fieldwork starts.

Searches for the top audit firms in Dubai, the big ten, or the big five return page after page of rankings, and essentially none of them disclose a methodology. Ours is the Top 10 audit firms in the UAE, with TaxAdvisors as our #1 pick for audit support. "Big Four" has a citable definition, and it is not a UAE one. Footnote 2 of the United States Government Accountability Office report GAO-03-864, Public Accounting Firms: Mandated Study on Consolidation and Competition (30 July 2003), names them as Deloitte & Touche LLP, Ernst & Young LLP, KPMG LLP and PricewaterhouseCoopers LLP, the 2003 legal entity names, which is why the modern brands differ. Footnote 8 of the same report defines the "Big 5" as those four plus Andersen. "Big ten" has no equivalent source at all; it is a marketing construct whose membership changes with whoever is publishing the list. The questions that separate firms are more mundane and more useful than any ranking: is the firm licensed to practise in the State under Federal Decree-Law No. 41 of 2023 and, where relevant, on your free zone's current approved list; who signs the report and how many years have they signed it; does the engagement team include someone who understands your sector; will related-party and transfer pricing work be done by the audit team or referred out; and what is the fee if the books turn out to need work. A firm that answers those directly is telling you more than a badge on a homepage.
