Corporate tax
Two filing deadlines land inside three days
The Federal Tax Authority used this week to repeat a date it has been repeating since the summer. Taxable persons whose tax period ended 31 December 2025 must file the corporate tax return and pay whatever is due by 30 September 2026. The window is nine months from the end of the tax period, which is where that date comes from. The Authority put it plainly: taxable persons are required to file their tax returns and pay the corporate tax due within a period not exceeding nine months from the end of each tax period. Nothing was said this week to suggest the date is moving.
What makes this week different from the last eight is the second date sitting next to it. The FTA calendar lists the final deadline for filing VAT returns as 28 September 2026, for monthly filers and for quarterly filers whose period closed on 31 August. That puts two separate filings inside three days, with the same finance person doing both. In a company of four people that is not a scheduling problem. It is the whole week.
Two points get missed every cycle. A return is required whether or not any tax is payable, so a dormant company, a first-year loss maker and a company relying on Small Business Relief all file. And relief is claimed in a return rather than assumed: revenue must not exceed AED 3,000,000 in the tax period and in every previous tax period. The FTA also restated the records position, warning that failure by a taxable person subject to corporate tax to maintain the required records and all other information specified under the Tax Procedures Law and the Corporate Tax Law will result in the application of the relevant administrative penalties. No penalty figures were published alongside the reminder.
- 30 Sep 2026 Corporate tax return and payment, for 31 Dec 2025 year ends
- 28 Sep 2026 VAT return deadline. Two days earlier, same finance team
Why it matters
Work backwards from 28 September, not from 30 September. The VAT return is the one that arrives first and it is the one most likely to get squeezed by the corporate tax work. If your year end is not 31 December, the 30 September date is not yours and your own nine months falls elsewhere, but the VAT date probably still is. File even where the tax due is nil. A dormant company files. A company claiming Small Business Relief files, because the claim lives in the return and silence is not an election.
- Every registered taxable person
- Free zone companies
- Dormant entities
This is the one item on the page with a penalty attached to missing it, which is why it sits first. The failure we see most often is not avoidance. It is a founder who reads no profit as no obligation, or who treats a free zone licence as somebody else’s filing problem. Neither reading survives contact with the law. The second failure is newer and belongs to this particular week: a small finance function that plans carefully for 30 September and then loses two days to a VAT return nobody diarised. If you have one person doing both, move the VAT work to Monday. And Again Advisory coordinates the filing and the paperwork. We do not approve anything and we do not promise a tax outcome. If your year end is not 31 December, read this section for the 28th and ignore the 30th.
