Yes — a UAE company can change its financial year end for corporate tax, but only with FTA approval and only by extending the current tax period to a maximum of 18 months or shortening the following one to between 6 and 12 months (Article 14(1) of Federal Decree-Law No. 47 of 2022; PwC tax summary, reviewed Sep 2026). The change follows FTA Decision No. 5 of 2023, and the deadline for the return shifts with it: nine months from the end of the new tax period.
TL;DR
- You can change your financial year end — with FTA approval, not by notice.
- Extend the current period to max 18 months, or shorten the next to 6-12 months.
- Valid reasons: reporting alignment, tax group, liquidation, commercial or legal grounds.
- Deadline moves: return and payment due 9 months from the new period end.
- Apply before filing the return for the period you want to change.
Why this matters
Your tax period is not a preference you set in software — it is a legal construct. For most UAE companies it is the 12-month financial year for which they prepare accounts, and corporate tax rides on top of it. When your reporting cycle no longer matches your group structure, your investor calendar or a tax group you joined, the fix exists but is gated: the FTA decides, on conditions set out in FTA Decision No. 5 of 2023.
There is also a trap to avoid. Some businesses assume the change happens by simply "closing the books early". Filing a return for a period the FTA has not approved creates a mismatch between your registration, your accounts and your filings — and that mismatch surfaces as a query, a penalty exposure or both.
What the law actually allows
Article 14(1) fixes the default: a taxable person's tax period is the Gregorian calendar year, or the 12-month period for which financial statements are prepared. Article 14(2) then allows a change only by application to the FTA. Under FTA Decision No. 5 of 2023, an approved change works through one of two mechanisms:
- Extend the current tax period to a maximum of 18 months (from its normal 12), or
- Shorten the following tax period to a minimum of 6 months and a maximum of 12 months.
The application needs a qualifying reason. The recognised grounds are:
- Aligning the financial year for tax grouping, financial reporting, or domestic and foreign tax relief purposes
- Liquidation
- A valid commercial, economic or legal reason
One more condition: the FTA's public clarification on the first tax period confirms that a newly incorporated company's first financial year — which under the Commercial Companies Law may run from 6 to 18 months — is accepted as the first tax period without an application, as long as it begins on or after 1 June 2023.
How the deadlines shift with a change
The corporate tax return and payment are due within 9 months from the end of the tax period (FTA Corporate Tax topics). When the period changes, the clock re-anchors:
| Scenario | Tax period | Filing + payment deadline | Effect |
|---|---|---|---|
| Default 12-month FY (Jan-Dec) | 1 Jan – 31 Dec 2026 | 30 Sep 2027 | Normal cycle |
| Extended current period | 1 Jan 2026 – 30 Jun 2027 (18 months) | 31 Mar 2028 | One extra return gap; then a normal 12-month cycle from 1 Jul 2027 |
| Shortened next period | 1 Jan – 30 Jun 2027 (6 months) | 31 Mar 2028 | Two returns in ~9 months; then alignment complete |
| First FY of a new company, 6-18 months | e.g. 1 Apr 2026 – 31 Mar 2027 | 31 Dec 2027 | No FTA application needed if FY begins on/after 1 Jun 2023 |
| Liquidation short period | Date of cessation decides | 9 months from that date | Separate application ground |
Note that thresholds do not pro-rate. The FTA's clarification states there is no pro-rating of thresholds such as the AED 3 million Small Business Relief revenue ceiling for a short or long period; the only exception is the AED 12 million de minimis for the general interest deduction limitation rule.
How to apply for a change, step by step
- Fix the reason first. Match your case to one of the accepted grounds in FTA Decision No. 5 of 2023 — reporting alignment, tax group, liquidation, or a valid commercial, economic or legal reason. Weak reasons are the most common rejection cause.
- File before the return is due. You must not yet have filed the return for the period you are asking to change.
- Submit the application through EmaraTax with your registration details, the proposed new period end date, and supporting documents — accounts to date, group structure where the reason is a tax group, or the board/liquidation documents.
- Wait for approval before filing. Do not file a return for the old period while an application is pending; the approved mechanism (extension or shortening) determines which period the return covers.
- Update your books and registration. Once approved, your registration record, accounting periods and filing calendar must reflect the new year end — including the 9-month deadline calculation.
Common mistakes
- Assuming the change is automatic. A change of financial year end in your accounting software does nothing to your tax period until the FTA approves it.
- Extending beyond 18 months or shortening below 6 months — outside the statutory bounds, the application fails.
- Filing for the old period while the application is open, which locks in a period you then have to unwind.
- Forgetting other registrations. VAT periods and licence renewals run on their own clocks; aligning the corporate tax period does not change them.
- Pro-rating thresholds that do not pro-rate, particularly Small Business Relief revenue ceilings in a short or long period.
FAQ
Can a UAE company change its financial year end for corporate tax?
Yes, with FTA approval under Article 14 of Federal Decree-Law No. 47 of 2022 and FTA Decision No. 5 of 2023. The current period can be extended to a maximum of 18 months, or the following one shortened to 6-12 months.
Do we need to give a reason?
Yes. Accepted grounds include aligning the year for a tax group, financial reporting or tax relief purposes, liquidation, and valid commercial, economic or legal reasons.
When is the return due after the change?
Within 9 months from the end of the new tax period. An 18-month period ending 30 June 2027, for example, files and pays by 31 March 2028.
Does a new company need to apply for its first period?
No. A first financial year of 6-18 months under the Commercial Companies Law is accepted as the first tax period without an application, provided it begins on or after 1 June 2023.
Is the AED 3 million Small Business Relief threshold pro-rated for a short year?
No. The FTA confirms thresholds are not pro-rated for a short or long tax period; the only exception is the AED 12 million de minimis for the interest limitation rule.
What happens if we just close the books early without applying?
Your tax period does not change. Filing against an unapproved period creates a mismatch with your FTA registration and exposes the company to queries and penalty risk.
One last thing
If the reason for your change is joining or forming a tax group, remember the group's members must share the same financial year end — the change is often the faster half of that project, not the harder one.
