The UAE corporate tax return deadline is 9 months after the end of your financial year. That sounds simple — but many UAE businesses are tripped up by a separate registration deadline, the document requirements, and a penalty structure that starts from day one of late filing.
This guide gives you a clear timeline, the exact documents you need, the penalty amounts for late filing and late payment, and a pre-filing checklist you can use every year.
CT deadlines are set by FTA decisions and ministerial decrees. Always confirm your specific deadline via the FTA EmaraTax portal or a licensed UAE tax advisor — particularly for your CT registration deadline, which differs from your CT return deadline.
Under UAE Corporate Tax Law, the CT return must be filed and any CT payable must be paid within 9 calendar months of the end of the financial year.
| Financial Year End | CT Return & Payment Deadline | First CT Period for June 2023 start |
|---|---|---|
| 31 December 2024 | 30 September 2025 | Yes — for Dec FYE businesses |
| 31 March 2025 | 31 December 2025 | Yes — for Mar FYE businesses |
| 30 June 2025 | 31 March 2026 | Yes — for Jun FYE businesses |
| 30 September 2025 | 30 June 2026 | Yes — for Sep FYE businesses |
| 31 December 2025 | 30 September 2026 | Second year for Dec FYE |
UAE CT registration (through EmaraTax) has a separate, earlier deadline based on your entity type and licence issue date — set out in Cabinet Decision No. 75 of 2023. Do not confuse your CT return deadline with your CT registration deadline. Registration penalties start at AED 10,000.
CT registration deadlines were issued on a staggered basis by the FTA depending on the month your UAE trade licence was issued. For most UAE businesses with licences issued between January and September, the registration deadline fell in 2024. Businesses incorporated after 1 March 2024 generally must register within 3 months of incorporation.
If you have not yet registered for UAE corporate tax, do so immediately through the EmaraTax portal — the late registration penalty is AED 10,000.
Here is what a business with a 31 December financial year end needs to do and when — using the 2025 financial year as an example:
You do not upload documents to EmaraTax — but you must have them prepared and available in case of an FTA review or audit. The CT return itself is a form you complete online.
Taxable income, adjustments, and transfer pricing disclosure data — all generated from your accounting records automatically.
| Violation | Penalty |
|---|---|
| Late CT registration | AED 10,000 (one-time) |
| Late CT return filing | AED 500/month for first 12 months; AED 1,000/month thereafter |
| Late CT payment | 14% per annum on unpaid CT, accruing monthly from the day after deadline |
| Failure to maintain accounting records | AED 10,000 (first offence); AED 20,000 (repeat) |
| Incorrect CT return (error discovered by FTA) | 50% of underpaid tax + fixed administrative penalty |
| Voluntary disclosure of error (before FTA audit) | Significantly reduced — typically 1–5% of underpaid tax |
The late filing penalty (AED 500/month) is separate from the late payment penalty (14% p.a. on tax due). If you cannot pay your CT bill by the deadline, filing the return on time limits your exposure to the payment penalty only — you avoid the filing penalty on top.
With a 9-month window, it is tempting to leave CT preparation late. But financial statement preparation, audit (if required), and CT adjustments take time — especially in year one. Starting 6 months before the deadline gives you time to identify errors and correct them before filing.
Failing to submit your corporate tax return on time triggers immediate penalties from the FTA. Understanding your submission timeline depends directly on your corporate financial year configuration.
Your entity concludes its annual financial cycle — e.g., December 31st for calendar year-ends. Books are formally locked and prepared for review.
Internal finance teams organize ledger balances, run depreciation tables, apply CT adjustments, and finalize net taxable figures. ETaxFlow does this continuously throughout the year.
The final deadline to submit your return on EmaraTax. Total corporate tax liabilities must be fully settled by this date to avoid late-payment fines of AED 500 per month.
A company with a December 31st financial year-end must file its CT return and pay any tax due no later than September 30th of the following year. Miss this date and penalties begin immediately — there is no grace period.
The UAE corporate tax return must be filed — and any CT payment made — within 9 months of the end of the financial year. For a company with a 31 December financial year end, the CT return is due by 30 September of the following year. For a 30 June financial year end, the deadline is 31 March.
Yes. UAE CT registration and CT return filing are two separate obligations with different deadlines. CT registration must be completed by the deadline assigned by the FTA based on entity type and licence issue date. Failure to register by the deadline incurs a penalty of AED 10,000.
Late filing of a UAE CT return incurs a fixed penalty of AED 500 per month for the first 12 months, and AED 1,000 per month thereafter. Late payment of CT incurs a penalty of 14% per annum on the unpaid amount, accruing monthly from the day after the deadline.
Businesses with revenue exceeding AED 50 million in a tax period are required to have their financial statements audited by a UAE-registered auditor. Businesses below this threshold may use reviewed or compiled financial statements, but must still maintain IFRS-compliant records.
There is currently no general extension mechanism for UAE CT filing deadlines. The FTA may grant extensions in exceptional circumstances at their discretion. It is advisable to begin preparing your CT return well before the 9-month deadline — particularly if your financial statements require audit.
