Corporate Tax Return Deadline: 30 September 2026 - What UAE Businesses Must Do Now?
UAE Corporate Tax Deadline 30 September 2026 | Filing Guide
If your business closed its financial year on 31 December 2025, your UAE Corporate Tax return is due by 30 September 2026. That is the hard stop for filing on EmaraTax and for settling any tax payable.
It is a date worth taking seriously. Filing a Corporate Tax return is not a formality that sits at the end of the accounting cycle, it is the point at which your financial statements, your transfer pricing position and your free zone status all become statements you have made to the Federal Tax Authority. Get them right, and you have a clean record. Get them wrong, or late, and you carry penalties and questions into the next cycle.
Who the 30 September deadline applies to?
The Corporate Tax return is due nine months after the end of the tax period. For businesses with a 31 December 2025 year-end, the return and any payment are due by 30 September 2026.
For other year-ends, the same nine-month rule applies. A business with a 31 March 2026 year-end has a filing and payment deadline of 31 December 2026. A 30 June 2026 year-end leads to a 31 March 2027 deadline, while a 30 September 2026 year-end leads to a 30 June 2027 deadline.
If your year-end is 31 December, 30 September is your date. There is no general extension mechanism for ordinary commercial reasons, and payment falls due on the same day as the return – not later.

Filing is mandatory, even when there is nothing to pay
This is the single most common misunderstanding we encounter.
Every taxable person registered for Corporate Tax must file a return for each tax period. That includes businesses that:
- made a loss for the year
- were dormant or had no trading activity
- earned income below the AED 375,000 threshold and pay tax at 0%
- elected Small Business Relief
- are Qualifying Free Zone Persons taxed at 0% on qualifying income
A nil return is still a return. Registration alone is not compliance, the FTA’s system records a registration and a filing obligation as two separate things, and only one of them is discharged when you register.
What you need before you can file?
A return cannot be assembled the night before. Work back from the deadline and make sure these are settled:
- Finalised financial statements. Accrual-basis accounts prepared under IFRS, or IFRS for SMEs where revenue does not exceed AED 50 million. These are the starting point for taxable income, so every adjustment downstream depends on them being final.
- The tax computation. Accounting profit adjusted for exempt income, non-deductible expenditure, interest limitation, unrealised gains and losses, and any reliefs claimed. Each adjustment needs a working paper behind it.
- Related party and connected person disclosures. Transactions with related parties and payments to connected persons must be disclosed, and must be on arm’s length terms. Where thresholds are met, a transfer pricing disclosure form accompanies the return, with a Local File and Master File held ready.
- Free zone analysis, if applicable. Qualifying Free Zone Person status is not a label that comes with the licence, it has to be evidenced each year: qualifying activities, adequate substance, the de minimis test, and no election out. A free zone entity that fails any limb of the test is taxed at 9% on all its income, not just part of it.
- Elections and reliefs. Small Business Relief, the realisation basis, tax group membership, transfers within a qualifying group, business restructuring relief most of these are made in the return itself and cannot be revisited later.
- A current EmaraTax profile. Active registration, correct authorised signatory, and up-to-date contact and licence details. An outdated authorised signatory is a slow, avoidable problem in the last week of September.
What missing the deadline costs?
Administrative penalties under Cabinet Decision No. 75 of 2023 can apply when a return is filed late. Late submission of the tax return carries AED 500 for each month, or part month, for the first 12 months, increasing to AED 1,000 per month from the 13th month.
Late settlement of payable tax carries a 14% per annum penalty applied monthly to the unpaid amount. An incorrect tax return can carry an AED 500 penalty unless it is corrected before the filing deadline.
A voluntary disclosure of an error carries a penalty of 1% per month on the tax difference from the original deadline. Failure to maintain records can result in AED 10,000, increasing to AED 20,000 for a repeat violation within 24 months.
The financial penalties are only part of the concern. A late or amended return can create additional scrutiny, while correcting an aggressive or unsupported position later can be more costly and more visible than getting the filing right the first time.
A realistic plan for the weeks remaining
Now: confirm the tax period, check EmaraTax access and the authorised signatory, and list what is outstanding in the accounts.
Two to three weeks out: close and sign the financial statements; complete the tax computation and the related party schedule.
One to two weeks out: review the free zone position and any elections; have the return reviewed by someone who did not prepare it.
Before 30 September: submit on EmaraTax and settle the payable tax the same day. Keep the acknowledgement and the supporting file together.

FAQ: UAE Corporate Tax Deadline 30 September 2026
Yes. Losses are reported through the return, and it is the return that carries the loss forward for offset against future taxable income.
A nil return is still required for each tax period from registration onwards.
There is no general extension for ordinary commercial reasons. Plan to file early rather than seek relief afterwards.
Yes. Qualifying Free Zone Persons file a return like any other taxable person, and the return is where the qualifying status is asserted and supported.
A voluntary disclosure corrects it, and carries a penalty of 1% per month on the tax difference from the original deadline. Earlier disclosure means a smaller penalty.
