Key takeaways
- Businesses whose tax period ended 31 December 2025 must file and pay by 30 September 2026 — the Federal Tax Authority has been actively reminding taxpayers of this date.
- A late return costs AED 500 for each month or part of a month for the first 12 months, rising to AED 1,000 a month after that — even if no tax is owed.
- Unpaid tax attracts a separate monthly penalty calculated at an annual rate of 14% on the outstanding amount.
- If you haven’t started, the priority now is gathering records and getting into EmaraTax today, not perfecting the numbers.
Who this week actually applies to
If your company’s financial year ran from 1 January to 31 December 2025, your corporate tax return and any payment due must reach the Federal Tax Authority by 30 September 2026. That is the general rule: a return is due nine months after the end of the relevant tax period, and for calendar-year businesses that nine-month clock now has one week left on it.
This applies whether you expect to pay tax or not. Companies claiming Small Business Relief still have to file — theirs is a simplified return, but it is still due on the same date. A nil return, a loss-making year, or a group structure with no tax payable does not exempt you from filing.
What this means for you: if your year-end was 31 December 2025 and you haven’t filed, you are inside the final week, not the final month.
The document checklist to pull together today
Most last-minute filings stall because the numbers aren’t ready, not because EmaraTax is confusing. Before you log in, have these ready:
- Final financial statements for the year to 31 December 2025 — profit and loss, balance sheet, and any adjustments already agreed with your accountant.
- A reconciliation of accounting profit to taxable income, including any exempt income, disallowed expenses and transfer pricing adjustments.
- Details of any tax group elections, Free Zone status, or Small Business Relief eligibility that affect how the return is prepared.
- Your EmaraTax login credentials and Tax Registration Number — check now, not on the day, that whoever holds the login still has access.
If your bookkeeping has fallen behind during the year, this is also where it catches up with you. Clean, up-to-date bookkeeping records are what let a return get finished in days rather than weeks. If your ledgers aren’t reconciled, that’s the first job, today, before anything else.
What this means for you: the filing itself is quick once the underlying numbers are settled. Chase the numbers first.
Step by step: filing on EmaraTax before the deadline
The corporate tax return is filed directly through the EmaraTax portal, which the Federal Tax Authority has confirmed is available around the clock in the run-up to the deadline. In practice, the process runs as follows:
- Log in to EmaraTax and confirm your Corporate Tax registration is active and the correct tax period is showing.
- Open the Corporate Tax return for the period ending 31 December 2025.
- Enter your accounting income and apply the adjustments needed to reach taxable income, including any reliefs or exemptions you’re claiming.
- Declare any Small Business Relief election, if applicable, using the simplified return fields.
- Review the calculated tax liability, then submit the return.
- If tax is payable, arrange payment through EmaraTax’s payment options before 30 September — filing and payment are both due by the same date.
Keep a copy of the submission confirmation and the return itself. If the Federal Tax Authority later opens an FTA audit or asks follow-up questions, this is the paperwork you’ll be asked to produce first.
What this means for you: the portal itself is rarely the bottleneck. Build in time for at least one internal review before you hit submit.
What happens if you miss the deadline
Missing 30 September 2026 triggers two separate penalties — one for the late return, one for any unpaid tax.
| Situation | Penalty |
|---|---|
| Return filed late | AED 500 per month or part month, for the first 12 months |
| Return still not filed after 12 months | AED 1,000 per month or part month, from month 13 onwards |
| Tax paid late | Monthly penalty calculated at an annual rate of 14% on the unpaid amount |
These penalties apply automatically once the deadline passes — they are not discretionary, and they apply even where the return would have shown zero tax due. A one-day delay costs the same first-month penalty as a three-week delay, so there is no advantage in waiting once 30 September has passed.
What this means for you: the cost of being one day late is fixed and starts immediately. There’s no grace period once the date passes.
If you genuinely can’t finish in time
If your accounts aren’t ready and 30 September is realistically not achievable, don’t wait until the last day to find that out. Get whatever figures you do have in front of a tax agent now — a return based on your best available numbers, filed on time, is a far better position than a perfect return filed late. Corrections can be made afterwards; the penalty clock cannot be reversed once it starts.
If the delay is due to incomplete bookkeeping rather than a tax question, treat that as the more urgent problem. A firm that can reconcile your accounts and prepare the return in parallel is usually the fastest route to filing this week rather than next month.
What this means for you: a rushed but accurate return, filed by the deadline, beats a delayed one every time the numbers allow it.
What to do now
With one week left: confirm your EmaraTax access today, pull together final accounts and the tax adjustment workings, and file as soon as the numbers are agreed rather than waiting for the final day. If Small Business Relief applies, don’t assume that removes the filing obligation — it doesn’t. If you’re not going to make it, get help now rather than on 29 September.
Frequently asked questions
Does the 30 September 2026 deadline apply to every UAE business?
It applies specifically to Taxable Persons whose tax period ended on 31 December 2025 — the standard calendar-year taxpayer. Businesses with a different financial year-end have a deadline nine months after their own year-end, which may fall on a different date.
Do I still need to file if my company made a loss or owes no tax?
Yes. The filing obligation is separate from whether tax is due. A nil or loss-making return still has to be submitted by the deadline, and the late-filing penalty applies regardless of the tax outcome.
Does claiming Small Business Relief remove the need to file?
No. Businesses eligible for Small Business Relief still file a simplified return by the same deadline. Relief changes what is calculated, not whether a return is required.
What if I file the return but haven’t paid the tax yet?
Filing and payment are both due by 30 September 2026. Filing on time avoids the late-filing penalty, but any unpaid tax still attracts the separate monthly late-payment penalty until it is settled.
Can the late-filing penalty be waived?
The Federal Tax Authority has, in specific circumstances, allowed relief connected to earlier registration timelines. For the annual return itself, the safest assumption is that the penalty applies from the day after the deadline, so filing on time remains the only reliable way to avoid it.
