UAE Corporate Tax Return Deadline 2026

The UAE Corporate Tax return deadline is 30 September 2026 for every business whose financial year ended on 31 December 2025. This applies whether the business made a profit, broke even, made a loss, or elected Small Business Relief: filing is mandatory in all four cases. The Federal Tax Authority (FTA) confirmed the deadline in a public reminder issued in September 2026, and no general extension has been announced.

Corporate Tax Deadlines by Financial Year-End

The 30 September 2026 date only applies to calendar-year businesses. Your actual deadline is always your financial year-end plus nine months, so check your registered Tax Period in EmaraTax rather than assuming.

Financial Year-End	Filing & Payment Deadline
31 December 2025	30 September 2026 (most common: calendar-year businesses)
31 January 2026	31 October 2026
29/28 February 2026	30 November 2026
31 March 2026	31 December 2026
30 April 2026	31 January 2027
31 May 2026	28 February 2027
30 June 2026	31 March 2027

Two businesses with different registration or trade licence renewal dates can still share the same filing deadline, because the deadline is driven by the Tax Period end date, not the registration date, licence date, or TRN issue date.

Who Must File by 30 September 2026?

Filing is a separate obligation from owing tax. A business can have zero tax due and still be legally required to file.

Profitable businesses — Must report taxable income and calculate Corporate Tax at the standard rate: 9% on taxable income above AED 375,000, and 0% below that threshold.
Zero-profit businesses — Must still submit a nil return confirming there is no taxable income or tax payable for the period. Having no profit does not remove the obligation to file.
Loss-making businesses — Must file to formally record the tax loss, which may be relevant for offsetting future taxable income under UAE Corporate Tax rules.
Small Business Relief electors — Must file a simplified return and make the SBR election within that return. The election is not automatic just because revenue is under the threshold. Revenue must not exceed AED 3 million for any relevant period up to 31 December 2026 to qualify.
Qualifying Free Zone Persons (QFZPs) — Must file through EmaraTax and confirm their qualifying conditions, even though qualifying income is taxed at 0%. QFZPs require audited financial statements regardless of revenue size.
Tax Groups — The Tax Group Parent files one consolidated return for the group, with audited Aggregated Financial Statements attached in line with FTA Decision No. 7 of 2025.
Natural persons (individuals and sole establishments) — An individual conducting business in the UAE whose revenue exceeds AED 1 million a year must register and file. For a calendar-year natural person, activity from 2025 is due by the same 30 September 2026 deadline.

The 7-Month Waiver: Does It Apply to Your 2026 Filing?

This is the detail most guides get wrong, so it is worth being precise about it.

In 2025, the FTA introduced a penalty waiver: businesses that missed their Corporate Tax registration deadline could avoid (or get refunded) the AED 10,000 late-registration penalty by filing their first Corporate Tax return within 7 months of their first Tax Period end, instead of the usual 9 months.

Important

This waiver applies only to a business’s first Tax Period. For most calendar-year businesses, the first Tax Period was 1 January to 31 December 2024, and that filing window has already passed. The return due on 30 September 2026 covers the 2025 Tax Period, a business’s second return, so the 7-month waiver generally does not apply to it. If you are unsure which Tax Period your upcoming return relates to, check EmaraTax before assuming any waiver is available.

Late Filing and Late Payment Penalties

Filing and payment are two separate obligations, and each carries its own penalty if missed.

Non-Compliance	Penalty
Late Corporate Tax return filing	AED 500 per month for months 1 to 12
Continued late filing (month 13 onward)	AED 1,000 per month, until filed
Late payment of Corporate Tax	14% per year on the unpaid amount
Incorrect return	AED 500 per incorrect return
Failure to maintain required records	AED 10,000 (first violation), AED 50,000 (repeat)
Failure to register for Corporate Tax	AED 10,000

This penalty structure comes from Cabinet Decision No. 129 of 2025, which took effect in April 2026. The late filing penalty accrues every month the return remains unsubmitted; it does not stop or cap itself, so the earlier a business files, the less it costs even if the return is already late.

What Happens If You Miss 30 September 2026?

For a business with a 31 December 2025 year-end:

Filing deadline: 30 September 2026
Late filing penalty starts accruing: 1 October 2026
Late payment penalty (if tax is unpaid): applies separately, calculated on the outstanding amount

If you are going to miss the deadline, filing as soon as possible, even a few days late, is still far cheaper than waiting. The AED 500 per month penalty is charged per month or part-month, so filing on 2 October costs the same one month’s penalty as filing on 28 October.

Filing Checklist Before 30 September 2026

Confirm your EmaraTax details

Check legal entity name, registered address, financial year-end, and Corporate Tax registration status.

Prepare the right financial statements for your category

Businesses with revenue exceeding AED 50 million: audited financial statements. QFZPs: audited financial statements, regardless of revenue. Tax Groups: audited Aggregated Financial Statements. Everyone else: IFRS-compliant management accounts.

Calculate the Corporate Tax liability

Review the accounting profit and make the relevant tax adjustments and reliefs.

Confirm Small Business Relief eligibility

If electing it, make the election inside the return itself.

Arrange payment early

Use your FTA payment channel. Do not rely on same-day processing near the deadline.

Can You File Early?

Yes. Once your Tax Period has ended and the return is available on EmaraTax, you can file before the deadline. Filing early reduces the risk of:

Last-minute technical or portal issues
Delays getting audited financial statements from your auditor
Computation or classification errors
Payment processing delays close to the cut-off

What If Your Auditor Isn’t Ready?

Contact your auditor immediately to confirm whether the required statements can realistically be completed before 30 September 2026. Where audited statements are not mandatory for your category, IFRS-compliant management accounts may be an acceptable alternative, but QFZPs and Tax Groups have stricter requirements with no equivalent shortcut. Because the correct path depends on your specific taxpayer status, get professional advice before submitting figures that might later need correcting through a voluntary disclosure.

FTA Enforcement Context

Enforcement has intensified alongside the filing push. In the first half of 2026, the FTA reported:

103,680 inspection visits, up 21% year-on-year
34,000 participants in FTA awareness events, up 23.3%
AED 174 million in liabilities and penalties tied to non-compliant excise products seized
19,300 retail outlets connected to the digital tourist VAT refund system
AED 353.5 million refunded to UAE nationals building new residences

The takeaway for businesses: compliance checks are increasing, which makes an accurate, on-time return more valuable than ever.

Frequently Asked Questions

What is the UAE Corporate Tax return deadline in 2026?

For businesses with a financial year ending 31 December 2025, the deadline is 30 September 2026, nine months after the financial year-end, per the FTA’s standard rule.

Do businesses with zero profit need to file?

Yes. A zero-profit or nil position does not remove the filing obligation. A nil return must still be submitted through EmaraTax by the deadline.

Do Small Business Relief businesses still need to file?

Yes. SBR is elected through the Corporate Tax return itself, so the return must still be filed even if no tax is ultimately due.

Is there an extension for the 30 September 2026 deadline?

No general extension has been announced. Businesses facing genuine delays should coordinate with their auditor and tax adviser immediately rather than wait for one.

What’s the penalty for late filing?

AED 500 per month for the first 12 months, rising to AED 1,000 per month from month 13 onward, until the return is filed.

Does the 7-month penalty waiver apply to this year’s return?

Generally no. That waiver applies only to a business’s first Corporate Tax return, and for most calendar-year businesses the first return was already due in 2025.

Where do I file?

Through the FTA’s EmaraTax platform, either directly or via an FTA-registered Tax Agent.

Does this apply to Free Zone companies?

Yes. Qualifying Free Zone Persons must file and confirm their qualifying status even where income is taxed at 0%, and must maintain audited financial statements regardless of revenue.
