Corporate Tax Deadline by Year-End
Your UAE corporate tax return and payment are one obligation, due nine months after your financial year-end under Article 53 of Federal Decree-Law No. 47 of 2022. So the date moves with your year-end: 30 November 2025 files by 31 August 2026, 31 December 2025 by 30 September 2026, 31 January 2026 by 31 October 2026, and 31 March 2026 by 31 December 2026. There are no extensions, and the payment must clear the FTA on the same date as the return. Check the year-end on your trade licence first, then add nine months and diarise it.

Nine months, no exceptions
The deadline is your year-end plus nine months.
- Return and payment share one date.
- No extensions are granted.
- Applies to every tax period after 1 Jun 2023.
- The FTA does not send tailored reminders.
Common year-ends
Add nine months to find yours.
- 30 Nov 2025 → 31 Aug 2026.
- 31 Dec 2025 → 30 Sep 2026.
- 31 Jan 2026 → 31 Oct 2026.
- 31 Mar 2026 → 31 Dec 2026.
Why 30 September misleads
It only fits one year-end.
- 30 Sep suits a 31 Dec year-end only.
- Earlier year-ends fall earlier.
- Assuming 30 Sep can leave you months late.
- One wrong assumption triggers penalties.

Frequently Asked Questions
For finding your corporate tax deadline.
How do I work out my CT deadline?
Take your financial year-end and add nine months. A 30 November 2025 year-end is due 31 August 2026; a 31 December 2025 year-end is due 30 September 2026.
Is the deadline always 30 September?
No. That date only applies to a 31 December year-end. Every other year-end has a different nine-month deadline.
Is the payment due on the same day?
Yes. The return and the tax payment are a single obligation due on the same date, and the payment must clear the FTA by then.
Are extensions available?
No. The nine-month deadline is fixed, so plan the filing and the cash for payment well ahead.
What if I miss it?
Administrative penalties apply for late filing and late payment, plus interest on unpaid tax, so the cost of a missed date often exceeds the tax.
Can Exiloz calculate and file this for me?
Yes. We confirm your year-end, calculate the tax, and file and settle before the deadline.
