Filing a UAE Corporate Tax Return in 2026: Deadlines, What the Return Contains, Small Business Relief and Penalties

Most UAE companies have now filed at least one corporate tax return, and the second and third rounds are where the mistakes show up: a missed election, a loss that wasn't recorded properly, or a payment made a week after the return. This guide is for owners, finance managers and bookkeepers of mainland and free zone companies and for individuals whose business turnover has crossed the threshold. It covers the 9 months deadline with dated examples for 2026 and 2027, what each part of the EmaraTax return asks, how to elect Small Business Relief, which financial statements and records you need, how to fix errors, and the penalties for filing or paying late.

Quick answer

A UAE corporate tax return must be filed on EmaraTax, and any tax paid, within 9 months of the end of each tax period — so a calendar-year company files its 2026 return by 30 September 2027. Every registered taxable person files, including loss-making and dormant companies. The return starts from your financial statements, adds the tax adjustments, records elections such as Small Business Relief, and calculates tax at 0% up to AED 375,000 and 9% above.

• Late filing: AED 500 a month for 12 months, then AED 1,000 a month

• Late payment: 14% a year, charged monthly on unpaid tax

• Small Business Relief is elected in the return, period by period — not afterwards

• Audited accounts only above AED 50 million revenue or for Qualifying Free Zone Persons

• Keep records for 7 years after each tax period

Who has to file a return

Article 53 of Federal Decree-Law No. 47 of 2022 requires every taxable person to file a return for each tax period, in the form the Federal Tax Authority (FTA) prescribes. In practice, if you hold a Corporate Tax Registration Number, you file. That includes companies with a loss, companies that didn't trade, and companies that will pay nothing because they elect Small Business Relief. If you should have registered and didn't, start with our corporate tax registration guide, because you can't file without a registration number.

Some returns are filed by someone other than the business itself. A tax group files one return through its parent company, covering all members. An unincorporated partnership that is treated as a taxable person files through its responsible partner. Exempt persons that the FTA has asked to register, such as some qualifying public benefit entities and investment funds, file an annual declaration rather than a full return. Natural persons whose business turnover exceeded AED 1 million file in their own name, with the calendar year as their tax period.

A return can be submitted by the taxable person, by a registered tax agent, or by a legal representative such as a liquidator. Using an agent doesn't move responsibility: penalties still fall on the business if the return is late or wrong.

The filing and payment deadline

The return is due no later than 9 months after the end of the tax period, and Article 48 makes the tax payable by the same date. Your tax period is your financial year: the calendar year, or the 12-month period for which you prepare financial statements. A new company's first period runs from incorporation to its first year end, so it can be shorter than 12 months; changing the period later needs an application to the FTA under Article 58.

There are no instalments or advance payments during the year. You pay once, with the return. The FTA's own reminder for 2026 was that 30 September 2026 was the deadline to file and pay for financial years ended 31 December 2025.

Article 53 lets the FTA direct a different filing date, but that's a power the authority uses by announcement, not an extension you can count on. Plan on the 9 months deadline. Weekends and public holidays near the due date don't help much either: EmaraTax accepts returns around the clock, and the penalty clock starts the day after the deadline.

A first tax period has its own quirks. If a company was incorporated on 1 March 2026 with a 31 December year end, its first period runs for ten months and its first return is due by 30 September 2027, just like a full year. Individuals don't get a choice: their tax period is always the calendar year, so a freelancer whose 2026 turnover passes AED 1 million files by 30 September 2027.

If you registered late and were charged the AED 10,000 penalty, there's an earlier date that matters for your first period only: file within 7 months of the first period's end and the penalty is cancelled automatically. For a first period ending 31 December 2026, that means filing by 31 July 2027 rather than 30 September 2027.

What the return contains

The law sets a minimum. Article 53 says a return must include the tax period, your name, address and registration number, the date of submission, the accounting basis of your financial statements, taxable income, tax losses used or transferred, tax credits claimed and the tax payable. The FTA's return guide turns that into a structured online form. The summary below follows the guide's layout as described by Deloitte; EmaraTax only shows the schedules that apply to your registration and the elections you make.

Some elections change the rest of the form. Electing Small Business Relief, for example, removes most of the computation because you're treated as having no taxable income. Elections such as the realisation basis, once made, carry forward and won't appear for selection again in later periods.

The return also has an attachments schedule. Financial statements are the one mandatory attachment in the guide's description; other supporting documents are optional unless the FTA asks for them. If your related-party transactions in the period exceed AED 40 million, you also complete the transfer pricing disclosure form with the return under Article 55.

Financial statements and records

You can't complete the accounting schedule without financial statements, so the real deadline for most companies is closing the books, not clicking submit. Statements are normally prepared under IFRS. Businesses with revenue of AED 3 million or less may use the cash basis of accounting under Ministerial Decision No. 114 of 2023, which simplifies things for many sole traders and micro companies.

Audited financial statements are required for corporate tax only in two cases, set by Ministerial Decision No. 82 of 2023: where revenue in the tax period exceeds AED 50 million, and for every Qualifying Free Zone Person, whatever its size. A free zone company that intends to claim 0% on qualifying income therefore needs an audit before it can file. Separately, many free zones and some banks require audited accounts for licence renewal or lending; that's their rule, not the FTA's, but it's sensible to produce one set of statements that serves both.

Article 56 requires you to keep the records and documents that support your return, and allow the FTA to work out your taxable income, for 7 years after the end of the tax period they relate to. That includes ledgers, invoices, bank statements, contracts, payroll records, fixed asset registers and the workings behind each adjustment. Failing to keep the required records costs AED 10,000, rising to AED 20,000 for a repeat within 24 months. If the FTA asks for documents in Arabic, they must be provided in Arabic.

Electing Small Business Relief in the return

Small Business Relief is the single most important decision in a small company's return. There's no separate application: you elect it in Part B, Elections, for each tax period. You can elect if you are UAE-resident, your revenue is AED 3 million or less in this period and every earlier one, and you're not a Qualifying Free Zone Person or a member of a large multinational group. Under Ministerial Decision No. 131 of 2026 the relief now runs for tax periods ending on or before 31 December 2029.

When you elect, you're treated as having no taxable income, the return asks for much less detail, and no tax is payable. The FTA's guide is clear that the election must be made in the return for the period. File without it and you can't claim the relief for that period afterwards.

Electing isn't always right. In an elected period you can't create, use or carry forward tax losses, so a loss-making start-up that elects throws its loss away. Our Small Business Relief guide works through when not to elect, with AED examples.

How to file and pay on EmaraTax

Filing a corporate tax return

1. 1

   Close the books

   Finalise the financial statements for the tax period, audited if you're above AED 50 million revenue or a Qualifying Free Zone Person.

2. 2

   Prepare the tax computation

   Start from accounting profit, add back non-deductible items such as half of client entertainment, remove exempt income, apply losses up to 75% of taxable income, and check related-party pricing.

3. 3

   Decide your elections

   Decide whether to elect Small Business Relief and any other Part B elections before you open the form.

4. 4

   Open the return on EmaraTax

   Sign in with UAE Pass, open the taxable person profile, and choose the corporate tax return for the right period.

   Open EmaraTax
5. 5

   Complete each part and attach statements

   Work through the parts EmaraTax shows, upload the financial statements and any transfer pricing disclosure, and review the calculated tax.

6. 6

   Submit and pay by the deadline

   Submit the declaration and pay the tax through EmaraTax within 9 months of the period end. Save the acknowledgement.

   Tip: Pay early enough for the money to reach the FTA by the due date; late payment penalties run from the following day.

Treat the computation as a separate exercise from the online form. Prepare it in a spreadsheet first, with each adjustment referenced to the ledger, then transfer the figures. That also gives you the working papers that Article 56 requires you to keep.

You can estimate the tax figure before you start with the UAE corporate tax calculator.

Worked example: a full return and the cost of being late

Gulf Lane Logistics LLC, a Sharjah mainland company with a calendar year, has revenue of AED 6.4 million in 2026, so Small Business Relief isn't available and audited accounts aren't required. Its 2026 return is due by 30 September 2027.

If it files and pays on time, it owes AED 53,100 by 30 September 2027.

If it files and pays three months late, on 30 December 2027, it faces two penalties. The late filing penalty is AED 500 for each month or part month: AED 1,500. The late payment penalty is 14% a year a year, charged monthly on the unpaid tax: AED 53,100 × 14% ÷ 12 × 3 = about AED 1,859. Together that's roughly AED 3,359 on top of the tax. After 12 months the filing penalty rises to AED 1,000 a month.

If it later finds an error. Suppose it discovers in 2028 that a AED 90,000 personal car lease for a director was wrongly deducted. Tax was understated by AED 8,100, which is under the AED 10,000 threshold described in the FTA's return guide, so it can correct it in its next return. Had the understated tax been AED 25,000, it would need a voluntary disclosure, paying a penalty of 1% a month of the difference for each month since the original due date, and paying the extra tax within 20 business days of submitting the disclosure.

Penalties and how to correct mistakes

Corporate tax penalties come from Cabinet Decision No. 75 of 2023 as amended. The ones that matter most at filing time are below.

Filing late costs AED 500 for each month or part month for the first 12 months, then AED 1,000 a month from the thirteenth month, starting the day after the deadline. Paying late costs 14% a year, charged monthly on whatever tax is still unpaid. Submitting an incorrect return costs AED 500, unless you correct it before the filing deadline. A voluntary disclosure of an error carries 1% a month of the tax difference for each month since the original due date. If you don't disclose before the FTA notifies you of an audit, the cost rises to a fixed 15% of the difference plus the same monthly charge. Not keeping the required records costs AED 10,000, or AED 20,000 for a repeat within 24 months.

Penalties stack. A return that is late, underpaid and later corrected can attract the late filing, late payment and voluntary disclosure penalties together, each calculated separately. That's why the cheapest fix is almost always the earliest one.

The order matters. An error you spot before the filing deadline can be fixed by resubmitting, with no incorrect-return penalty. After the deadline, small errors (tax understated by AED 10,000 or less in total) go into a later return. Larger ones need a voluntary disclosure, which costs far less if you make it before the FTA tells you it will audit you.

Overpayments work the other way. From 1 January 2026, Federal Decree-Law No. 17 of 2025 amended the Tax Procedures Law so that a credit balance must be reclaimed or used within five years of the end of the relevant tax period, or it can be lost. A company that overpaid in an early period should check its EmaraTax balance now.

Common filing mistakes

Forgetting the election. A company that qualifies for Small Business Relief but files without electing loses it for that period. Decide before you start the form.

Electing in a loss year. The opposite mistake: electing throws away a tax loss you could have carried forward.

Treating the return as a VAT return. The figures come from your financial statements, not your VAT returns. Revenue in the accounting schedule often differs from VAT taxable supplies because of exempt and out-of-scope sales, and that's fine as long as both are right.

Missing adjustments. The usual ones are the 50% entertainment add-back, fines and penalties, personal expenses paid by the company, and related-party transactions that weren't at arm's length, such as a rent-free office in a shareholder's building.

Paying late while filing on time. The deadlines are the same day. A return filed on 30 September with payment on 2 October still triggers the late payment penalty.

Assuming last year's details are right. Part A is pre-filled. If the address, activities or signatories have changed, update the registration as well, or face a AED 1,000 penalty for not notifying the FTA.

Frequently asked questions

When is the UAE corporate tax return due?

Within 9 months of the end of your tax period, and any tax must be paid by the same date. For a financial year ending 31 December 2025 the deadline was 30 September 2026. A year ending 31 March 2026 is due by 31 December 2026, and the 2026 calendar year by 30 September 2027.

Do I have to file a corporate tax return if my company made a loss?

Yes. Every registered taxable person files a return for each tax period, whatever the result. A loss-making company's return is how it records the tax loss to carry forward against future profits, capped at 75% of taxable income in the year of use. A company with no activity still files.

Do I need audited financial statements to file?

Only if your revenue exceeds AED 50 million in the tax period or you're a Qualifying Free Zone Person, under Ministerial Decision No. 82 of 2023. Everyone else still needs financial statements to complete the return's accounting schedule, but they don't have to be audited for corporate tax purposes. Your free zone or bank may separately require an audit.

How do I claim Small Business Relief in the return?

In Part B, Elections, choose Small Business Relief for the tax period. You can only elect if revenue is AED 3 million or less in this period and every earlier one and you aren't excluded. The return then asks for less detail. If you file without electing, you can't add the election later for that period.

What is the penalty for filing a corporate tax return late?

AED 500 for each month or part month for the first 12 months, then AED 1,000 a month after that. Tax paid late attracts a separate penalty of 14% a year, charged monthly on the unpaid amount. Both are set by Cabinet Decision No. 75 of 2023.

Can I correct a corporate tax return after filing?

Yes. If the error means tax was understated by AED 10,000 or less, you can correct it in a later return. Larger errors need a voluntary disclosure on EmaraTax, which carries a penalty of 1% a month of the tax difference. Waiting until the FTA announces an audit adds a 15% fixed penalty.
