Corporate tax
The return deadline passed, and the meter is now running
The corporate tax return and payment for taxable persons whose tax period ended on 31 December 2025 fell due on 30 September 2026, nine months after the year end. The Federal Tax Authority had repeated the date through the summer. For a company with a calendar year, this is the day the whole of 2025 is answered for: the return, the tax due on it, and the records that sit behind both.
The penalties are fixed in advance. Under Cabinet Decision No. 10 of 2024, a late return costs AED 500 for each month or part of a month during the first twelve months, and AED 1,000 for each month after that. A return filed on 01 October is therefore a month late, not a day late. Unpaid tax is a separate charge. Under Cabinet Decision No. 129 of 2025, in force since 14 April 2026, it runs at 14 per cent a year on the outstanding balance, roughly 1.17 per cent a month, until the tax is paid.
The two charges behave differently, and that is the point most businesses miss. The filing penalty is small, fixed and indifferent to how much tax you owe. The payment charge scales with the liability: AED 200,000 of tax paid six months late costs about AED 14,000 on top. A dormant company, or a free zone entity that expects to pay nothing, can still collect the filing penalty, because the obligation is to file, not to pay. And the return is where a free zone company states its position on the qualifying rate. A position that is never filed is a position nobody has seen.
- AED 500 A month for a late return, first twelve months
- 14% A year on unpaid tax, charged separately
If you missed 30 September
- File now, even at nil. The filing penalty grows by the month, and a part month counts as a whole one.
- Pay what is due as a separate step. The 14 per cent runs on the balance, so a partial payment still reduces it.
- Check whether a registration penalty sits on the same file. It had its own rules and its own earlier date.
- If you intend to ask the FTA to reconsider a penalty, keep the evidence of why the return was late.
- Companies with 31 December year ends
- Dormant companies
- Free zone entities
Most of the companies we set up file on time, because the date is in front of them. The ones that do not are usually the quiet ones: a holding company with no revenue, a free zone licence kept alive for a visa, a mainland company that paused trading. They rarely miss the date through carelessness. They miss it because they decide it does not apply to them. It does. If your return is filed and your payment made, this story is already behind you. If not, the cheapest day to file is today, because every new month adds another AED 500 before the tax itself is counted.
