Answer first: Your first UAE corporate tax return is due within 9 months of your financial year-end - 30 September 2026 for a 31 December 2025 year-end. Filing and payment are a single obligation: the return submitted on EmaraTax includes the tax computation, and the tax must be paid by the same deadline. Missing it triggers escalating FTA penalties that compound quickly. Here is every deadline and every penalty you need to track.

UAE considerations
For UAE readers, the practical issue is rarely the headline tax concept alone. The decision depends on the company type, tax period, EmaraTax status, books, relief position, and whether the business operates from a mainland or free zone structure. Use this with Finsera's UAE corporate tax registration and filing page and monthly bookkeeping support so the tax position is tied back to records, not assumptions. Treat this guide as a planning aid, then verify the live position against FTA or Ministry of Finance guidance before filing or paying tax.
Common questions
- When is my UAE corporate tax return due? Within 9 months of your financial year-end. For a 31 December year-end, the return is due by 30 September of the following year. For a 31 March year-end, it is due by 31 December. Filing and payment share the same deadline.
- What is the penalty for filing my corporate tax return late? AED 500 per month for the first 12 months of delay, escalating to AED 1,000 per month thereafter. These are cumulative - 6 months late costs AED 3,000 in filing penalties alone, before any late-payment penalties on the tax itself.
The Key Dates for 2026
The 9-month filing rule applies to all corporate tax registrants. Your deadline depends on your financial year-end.
| Financial Year-End | First Tax Period Ends | Registration Deadline (new cos) | Corporate Tax Return Due | Tax Payment Due |
|---|---|---|---|---|
| 31 December 2025 | 31 Dec 2025 | Within 3 months of incorporation | 30 Sep 2026 | 30 Sep 2026 |
| 31 March 2026 | 31 Mar 2026 | Within 3 months of incorporation | 31 Dec 2026 | 31 Dec 2026 |
| 30 June 2026 | 30 Jun 2026 | Within 3 months of incorporation | 31 Mar 2027 | 31 Mar 2027 |
| 30 September 2026 | 30 Sep 2026 | Within 3 months of incorporation | 30 Jun 2027 | 30 Jun 2027 |
| 31 December 2026 | 31 Dec 2026 | Within 3 months of incorporation | 30 Sep 2027 | 30 Sep 2027 |
For natural persons (freelancers and sole proprietors), the registration deadline is 31 March of the year following the calendar year in which turnover crossed AED 1 million. A freelancer who exceeded AED 1 million in 2025 must register by 31 March 2026. Their first tax period is the calendar year, so the first return is due by 30 September 2026.
The standard tax period is the Gregorian calendar year (1 January to 31 December) unless the business has a different financial year approved by the FTA. Most UAE companies use 31 December. Free zone entities aligned with foreign parent reporting may use a different year-end but must notify the FTA.

The Full FTA Penalty Schedule
FTA penalties for corporate tax non-compliance are set out in Cabinet Decision No. 49 of 2021 (as amended) and FTA Decision No. 3 of 2024. The amounts are fixed and non-negotiable unless a waiver applies.
| Violation | Penalty | Legal Basis |
|---|---|---|
| Late registration for corporate tax | AED 10,000 (fixed) | Cabinet Decision No. 49 of 2021 |
| Late filing of corporate tax return | AED 500 per month for first 12 months; AED 1,000 per month thereafter | FTA Decision No. 3 of 2024 |
| Late payment of corporate tax | 14% per annum on unpaid tax, calculated monthly | Cabinet Decision No. 49 of 2021 |
| Failure to maintain proper records | From AED 10,000 | Cabinet Decision No. 49 of 2021 |
| Failure to submit data/documents upon FTA request | AED 500-AED 5,000 per instance | Cabinet Decision No. 49 of 2021 |
| Incorrect return or tax position | AED 500-AED 3,000 depending on severity | FTA Decision No. 3 of 2024 |
| Tax evasion | 300% of the evaded tax amount | Federal Decree-Law No. 47 of 2022 |
The late-payment penalty of 14% per annum is particularly aggressive. A business with AED 100,000 in unpaid tax that is 6 months late faces approximately AED 7,000 in additional penalties on top of the tax itself. The penalty compounds - it is calculated monthly on the outstanding balance including previously accrued penalties.

Filing and Payment Are One Obligation
The UAE corporate tax return is both a filing and a payment event. When you submit the return on EmaraTax, the system computes the tax due. Payment must be made by the same 9-month deadline. There is no separate payment deadline extension - the filing extension (if granted) covers both.
The standard payment methods on EmaraTax are:
- eDirham (direct debit from a UAE bank account)
- Credit card (subject to card processing limits)
- Bank transfer to the FTA's designated account with the reference number
Payment must clear by the deadline. Initiating a transfer on the due date that settles later does not satisfy the obligation. The FTA timestamps compliance based on cleared funds, not initiation.
For businesses with taxable income above AED 375,000, the tax computation is: 0% on the first AED 375,000 plus 9% on the remainder. A business with AED 1,000,000 in taxable income pays AED 56,250: zero on the first AED 375,000 and 9% of AED 625,000.
The Penalty Waiver: File Within 7 Months
The FTA introduced a critical relief measure for late registrants. If you missed the registration deadline and were issued the AED 10,000 penalty, you can have it waived entirely by filing your first corporate tax return within 7 months of your first tax period end - rather than the standard 9 months. This means acting 2 months earlier than the normal deadline.
This waiver was formalised in FTA administrative decisions issued in 2024 and confirmed to remain active through 2026. It is not an automatic waiver - the penalty is applied and then removed after the timely filing is verified. The mechanism is:
- Register on EmaraTax (the AED 10,000 penalty is assessed)
- Prepare and submit the first corporate tax return within 7 months of the tax period end
- The FTA system waives the AED 10,000 penalty upon acceptance of the return
The waiver applies only to the registration penalty. Separate late-filing and late-payment penalties continue to apply if the 7-month window is also missed. For a 31 December 2025 year-end, the waiver deadline is 31 July 2026 - not 30 September 2026.

How to Never Miss a Deadline Again
Corporate tax compliance is annual, but the penalties are severe enough to warrant a systematic approach. UAE businesses should implement:
- A compliance calendar - map registration, filing, and payment deadlines by entity for the full year. Update it whenever the financial year-end changes.
- Monthly bookkeeping - reconciled books by the 10th of each month ensure the tax computation is ready well before the 9-month filing window. Our bookkeeping service maintains this cadence.
- Quarterly tax reviews - a mid-year review of revenue against the AED 375,000 threshold and (for eligible businesses) the AED 3 million Small Business Relief ceiling avoids surprises.
- Automated reminders - set alerts 90, 60, and 30 days before each deadline. The FTA does not send reminders; compliance is the taxpayer's responsibility.
- Agent authorisation - designate a tax agent or corporate service provider with FTA access to monitor deadlines and receive notifications on your behalf.
The FTA's position is clear: ignorance of the deadline is not a defence. Penalties are assessed automatically by the EmaraTax system and must be paid before any objection or reconsideration can be filed.
