Not for every company. An audit is mandatory in the UAE if you are a mainland LLC, a Qualifying Free Zone Person or a tax group. It is also mandatory if your revenue exceeds AED 50 million or your free zone requires one. Three separate rules create these triggers, and you can pass one test and fail another.
Quick Answer: When Is an Audit Mandatory in the UAE?
Check these five triggers. Any one makes an audit mandatory in the UAE for your 2026 accounts.
- You are a mainland LLC, whatever your revenue (Commercial Companies Law)
- You are a Qualifying Free Zone Person, whatever your revenue (corporate tax)
- You are a tax group, which must prepare audited special-purpose aggregated financial statements (corporate tax)
- You are not in a tax group, and your revenue exceeds AED 50 million (corporate tax)
- Your free zone authority requires annual audited accounts (free zone rules)
The sections below cover each rule, its deadline and the penalties for missing it.
Is Audit Mandatory in the UAE for Corporate Tax?
The corporate tax law does not require every taxable person to be audited. The Ministry of Finance decides which taxpayers must keep audited financial statements for UAE corporate tax. Since 2025, there are three categories.
The Three Categories Under Ministerial Decision 84
Ministerial Decision No. 84 of 2025 applies to tax periods starting on or after January 1, 2025. It replaced Ministerial Decision 82 of 2023, which still governs earlier periods. You need an audit for corporate tax if you fall into any one of these categories.
- You are not in a tax group, and your revenue exceeds AED 50 million in the tax period.
- You are a Qualifying Free Zone Person, whatever your revenue.
- You are a tax group. You need audited special-purpose aggregated statements under FTA Decision No. 7 of 2025.
If you are a non-resident, only revenue from your UAE permanent establishment and/or nexus counts toward AED 50 million. Say your UAE branch earns AED 20 million and your worldwide revenue is AED 300 million. You are below the threshold. Your home-country audit is a separate matter.
What the AED 50 Million Revenue Test Measures
Revenue means gross income for the tax period, before expenses. It is the figure in your financial statements. The rule applies when revenue exceeds AED 50 million. Revenue of exactly AED 50 million does not trigger it. Each tax period is tested on its own. If you pass AED 50 million once, you need an audit for that period, even if revenue falls the next year.
| Your position | Audited statements for corporate tax | Why |
|---|---|---|
| Mainland company, not in a tax group, revenue AED 30 million | Not required | Below the threshold |
| Mainland company, not in a tax group, revenue AED 60 million | Required | Revenue exceeds AED 50 million |
| Qualifying Free Zone Person, revenue AED 4 million | Required | No threshold. Applies even if some income is taxed at 9 percent |
| Free zone company on the standard regime, not a Qualifying Free Zone Person, not in a tax group, revenue AED 4 million | Not required for corporate tax | Below the threshold |
| Tax group, combined revenue AED 12 million | Required, special-purpose aggregated statements | Every tax group since 2025 |
| Foreign company, UAE branch revenue AED 20 million | Not required | Only UAE permanent establishment and/or nexus revenue counts |
The Standards and the Deadline
Most companies prepare corporate tax financial statements on an accrual basis under IFRS. If your revenue is AED 50 million or less, you may use IFRS for SMEs. If your revenue does not exceed AED 3 million, Ministerial Decision No. 114 of 2023 lets you use cash-basis accounting. The FTA can also allow cash basis in exceptional cases, on application.
If you need an audit because your revenue exceeded AED 50 million, you use full IFRS. Tax groups build their aggregated statements from their members’ IFRS-based statements. They apply the adjustments in FTA Decision No. 7 of 2025. The audit follows International Standards on Auditing.
Your corporate tax return is due nine months after the tax period ends. For a December 2026 year-end, you file by September 30, 2027. Your audit must be finished before you file. Plan backward from that date so the signed report arrives well before the deadline.
Is Audit Mandatory for Free Zone Companies in the UAE?
The audit requirement for a free zone company in the UAE comes from two places: the corporate tax rule and your free zone authority’s rules. These are separate obligations with separate conditions. One set of audited statements can satisfy both if it meets both sets of rules. ADGM’s guidance describes this overlap.
The Qualifying Free Zone Person Rule
The 0 percent rate on qualifying income is conditional. An audit is one of the conditions. As a Qualifying Free Zone Person, you must keep audited financial statements every tax period, whatever your revenue. This applies even though you pay 9 percent on non-qualifying income. If you skip the audit, you fail the conditions for that period. Standard rates then apply for that period and the next four. Our guide to keeping Qualifying Free Zone Person status covers each condition.
Under the Corporate Tax Law, you must meet all of these conditions:
- Audited financial statements every period, with no revenue floor
- Adequate substance in the free zone, or the Designated Zone for distribution, with appropriate assets, staff and operating expenditure. You may outsource, subject to the applicable location and supervision requirements
- Qualifying income. This includes income from qualifying activities under Ministerial Decision 229 of 2025 and qualifying transactions with other Free Zone Persons
- Non-qualifying revenue within the de minimis limit
- No election to be taxed under the standard corporate tax regime
- Transfer pricing compliance on related-party transactions
The Extra Report for Designated Zone Distributors
Some Qualifying Free Zone Persons distribute goods or materials in or from a Designated Zone. If you do, you have an extra obligation from tax periods starting on or after January 1, 2026. FTA Decision No. 6 of 2026 requires an agreed-upon procedures report under ISRS 4400. An independent UAE-licensed auditor issues it.
The report checks two things. Your customers bought the goods for resale or for processing for sale. Any goods you imported into the UAE entered through a Designated Zone. The report is due within 30 days after your corporate tax return deadline, unless the FTA sets another date. It is separate from your financial statement audit, so plan both together.
Free Zone Annual Audit and Filing Requirements
Many free zone authorities require you to submit audited financial statements each year. This applies whatever your corporate tax position. Each authority sets its own deadline, auditor rules and penalties. The table shows how they differ.
| Free zone | Annual audit requirement | Submission window after year-end |
|---|---|---|
| DMCC | Required. Your auditor must be on the DMCC Approved Auditors List. Submit through the Member Portal with a signed, stamped summary sheet. Branches with a group auditor are exempt from the list rule but must still submit. | Six months (June 30, 2027 for a December 2026 year-end) |
| JAFZA | Required for FZE and FZCO entities. Submit through the Dubai Trade portal. Your auditor must meet JAFZA’s licensing requirements. | Confirm with JAFZA |
| DIFC | Required, unless the small private company exemption applies (see DIFC note) | Six months, then file within 30 days after circulation (see DIFC note) |
| ADGM | Required, unless an ADGM audit exemption applies (see ADGM note) | Normally nine months for private companies |
| RAKEZ | Required. Your auditor must be on the RAKEZ approved auditors list. | Confirm with RAKEZ |
| IFZA, Meydan and others | Varies by licence type and authority | Per the authority’s rules |
DIFC note: You qualify as a small private company if your turnover is US$5 million or less, consolidated with subsidiaries, and you have no more than 20 shareholders. Both tests apply to the current and, where relevant, the preceding year. Your articles can still require an audit, and shareholders with at least 10 percent can demand one. DFSA-regulated firms must be audited under DIFC rules. A Qualifying Free Zone Person also needs an audit for corporate tax. Under the DIFC Companies Law, you complete the accounts procedures within six months of year-end. You then file with the Registrar within 30 days after circulation to shareholders. Confirm the current deadline with the DIFC Registrar.
ADGM note: Exemptions cover eligible small companies, certain subsidiaries and dormant companies. A small company has turnover of US$13.5 million or less and no more than 35 employees. Exclusions, group rules and a two-year rule apply. A Qualifying Free Zone Person must still keep audited statements for corporate tax, even if small or dormant. Its auditor must be ADGM-registered (ADGM QFZP guidance). A small company that prepares general-purpose audited statements must file them with the Registrar. Special rules can change the nine-month window for a first accounting period.
These filing rules can catch you when the corporate tax rule does not. Take a DMCC company that is not a Qualifying Free Zone Person, with AED 3 million of revenue. It has no corporate tax audit requirement. It still has to submit audited statements to DMCC. Depending on the authority, a missed filing can bring fines, renewal delays or other restrictions. Some authorities link the free zone annual audit to licence renewal, so check your renewal notice.
The Approved Auditor Requirement
Some free zones accept audit reports only from their own approved list. Others set licensing conditions for auditors. Your authority may reject a report from a firm that does not meet its rules. Before you engage an auditor, confirm three things with your authority.
- Whether it keeps an approved list or sets licensing conditions, and whether your firm meets them
- Whether it requires the auditor’s registration number on the report
- Whether you must submit the report through its portal rather than by email
Check the authority’s current list yourself. Do not rely on the firm’s word. Get the answer before you sign the engagement letter.
Is Audit Mandatory for Mainland Companies in the UAE?
If you run a mainland company, a company law rule applies on top of the corporate tax rule. A mainland audit can be mandatory under either one.
The Commercial Companies Law Rule
Federal Decree-Law No. 32 of 2021 applies to every mainland limited liability company. You must appoint a registered auditor and audit your annual financial statements, whatever your revenue. Your annual general assembly approves the audited accounts. You keep them for at least five years.
A single-shareholder LLC is inside the rule. So is a mainland branch of a foreign company, which files audited accounts with the Ministry of Economy. Representative offices are outside that branch audit requirement.
The company law audit rule covers companies, such as LLCs. Sole establishments and civil companies are outside it. They still need an audit if another rule applies, such as revenue above AED 50 million. A bank or licensing authority may also ask for audited statements.
For corporate tax, you must keep relevant records for at least seven years after the tax period ends (FTA). Seven years is the corporate tax minimum. Other authorities can require longer. ADGM, for example, requires you to keep accounting records for at least ten years from creation.
Banks, buyers and licence authorities can ask for audited statements. If you have never been audited, you may find the gap when you apply for a loan or sell a stake.
Penalties for Not Having a Required Audit
The consequences depend on which rule you breached. As a free zone company, you can breach two at once.
- Corporate tax: Failing to keep required records and information carries a penalty of AED 10,000. A repeat within 24 months carries AED 20,000. These penalties come from Cabinet Decision No. 75 of 2023. Audited statements you must maintain are part of those records.
- Qualifying Free Zone Person: You lose the 0 percent rate for the period of the failure and the next four tax periods.
- Free zone filing: You may face fines, renewal delays or other restrictions, depending on the authority.
- Company law: You may face fines under the Commercial Companies Law.
For a Qualifying Free Zone Person, losing the 0 percent rate can cost far more than the fine. Say you have AED 4 million of taxable income and lose your status. You pay 9 percent on the income above AED 375,000. That is AED 326,250 for the period. Standard rates then apply for the next four periods. The tax for each depends on that period’s taxable income.
Audit Timeline for a December 2026 Year-End
How long your audit takes depends on your company’s size and the state of your books. Unreconciled ledgers add time. Your shortest deadline sets the end date. If you are a free zone company, your authority’s filing deadline may fall before the corporate tax deadline.
The calendar below is for a December 2026 year-end. Confirm your authority’s deadline. Move the dates earlier if it is shorter than six months.
| Step | When (December 2026 year-end) | Who |
|---|---|---|
| Engage your auditor, check your authority’s auditor rules, plan and send the document request | November to December 2026 | Auditor and your finance team |
| Close the year and reconcile accounts | January 2027 | Your accountant |
| Fieldwork and queries | February to March 2027 | Auditor |
| Draft statements and management letter | April 2027 | Auditor |
| Sign the report and file with your free zone, if required | Before your authority’s deadline (June 30, 2027 for DMCC and other six-month zones) | Auditor and you |
| File the corporate tax return on the audited statements | By September 30, 2027 | Your tax agent |
| Submit the agreed-upon procedures report (Designated Zone distributors only) | Within 30 days after the return deadline | Auditor and you |
If you engage your auditor in May, you are racing the six-month free zone windows. Starting in November leaves room for queries and for any shorter deadline.
If you need an audit, engage your auditor now, not after year-end. Planning early leaves time for the document request and queries.

Frequently Asked Questions
My free zone company is on the standard corporate tax regime, is not a Qualifying Free Zone Person and earns AED 2 million. Do I need an audit?
Not for corporate tax, as long as three things are true. You are not a Qualifying Free Zone Person. You are not in a tax group. Your revenue is AED 50 million or less. Paying 9 percent on some income does not prove you are outside Qualifying Free Zone Person status. A Qualifying Free Zone Person also pays 9 percent on non-qualifying income and still needs audited statements. Your free zone authority may also require an audit, so check its rules as well.
Does a company in a tax group need its own audited statements as well as the group’s?
Ministerial Decision 84 requires your tax group to prepare audited special-purpose financial statements. FTA Decision No. 7 of 2025 sets out how. The group combines the standalone statements of the parent and each subsidiary. It removes intra-group transactions. An auditor audits the combined statements under International Standards on Auditing. The group submits them to the FTA within nine months of the tax period end.
Members do not need a separate corporate tax audit just because they are in the group. A member still needs its own audit if its free zone, its licence or the Commercial Companies Law requires one.
I crossed AED 50 million this year for the first time. When does the audit apply?
To this tax period. The threshold is tested each period. It applies when your revenue exceeds AED 50 million. You need audited statements for the year you cross it, and you file that year’s return on them. Engage your auditor as soon as crossing looks likely.
Can I use an auditor who is not on my free zone’s approved list?
For corporate tax, your auditor must be registered with the Ministry of Economy. Your auditor must also meet any free zone or regulatory registration rules that apply to you. In ADGM, for example, a Qualifying Free Zone Person’s auditor must be ADGM-registered. Some authorities, such as DMCC and RAKEZ, keep an approved list. They may reject a report from a firm outside it, and you may then need a listed auditor to issue a new report. Confirm the requirements before you sign an engagement letter.
What if my books are not ready for an audit?
Unreconciled ledgers slow your audit and can affect the auditor’s opinion. Do the accounting cleanup first, then the audit. Start the cleanup well before your deadline. Leave your auditor enough time to finish after it.
Is there an audit threshold for small companies in the UAE?
There is no single audit threshold. The AED 50 million test applies only to the corporate tax rule. A mainland LLC needs an audit whatever its revenue. So does a Qualifying Free Zone Person. Some free zones exempt small companies, such as qualifying DIFC and ADGM companies. Check every rule that applies to you.
Does Small Business Relief remove the audit requirement?
No. Small Business Relief changes how much corporate tax you pay, not whether you need an audit. It is not available to a Qualifying Free Zone Person. It also does not change the company law rule for LLCs or your free zone’s filing rules.
