UAE Tax Procedures Law: Five-Year Refund Deadline and Stronger FTA Powers Take Effect January 2026
The UAE Ministry of Finance has implemented major amendments to the Tax Procedures Law through Federal Decree-Law No. 17 of 2025, effective January 1, 2026. These changes introduce clearer timelines for tax refunds, expanded audit authorities, and binding tax guidance—significantly reshaping how businesses interact with the Federal Tax Authority (FTA).
Key Changes for Your Business
Fixed Five-Year Refund Window
The most significant change establishes a hard deadline: businesses now have exactly five years from the end of a tax period to claim a refund or credit balance across all federal taxes (Corporate Tax, VAT, and Excise Tax). This eliminates previous ambiguity and provides clarity for financial planning. However, if you miss this window, you lose the right to claim the refund permanently—making timely action critical.
There is limited flexibility for claims arising in the final 90 days of the five-year period or following a late FTA decision; these may be claimed within specific timeframes (90 days to one year, depending on circumstances).
Strengthened FTA Audit Powers
The FTA can now conduct audits beyond the standard five-year period in clearly defined cases—notably when you submit a refund request in the final year. This allows the authority to verify claims submitted close to deadlines. Any extended audit must be completed within two years from the date you submit your refund request.
Binding Tax Interpretations
A structural change gives the FTA authority to issue official, binding directions clarifying how tax rules apply. These directions bind both taxpayers and the FTA itself, reducing inconsistent interpretations and creating a more predictable compliance environment.
Simplified VAT Processes
From January 1, 2026, VAT-registered businesses no longer need to self-issue tax invoices for imports of goods or services subject to reverse charge mechanisms. Errors that do not affect the amount of tax due can now be corrected directly through your tax return, eliminating unnecessary voluntary disclosure requirements.
Transitional Relief for Older Claims
If your five-year refund window expired before January 1, 2026, or expires within one year after that date, you receive a new one-year window starting January 1, 2026 to file refund requests. You may also submit a Voluntary Disclosure within two years of filing such a request if the FTA has not yet decided.
What This Means
Act now on overdue refunds: If you have credit balances or pending refunds, submit claims immediately. The five-year deadline is now legally enforced, and delays could result in permanent loss of entitlements.
Strengthen your documentation: With expanded audit powers and binding FTA directions, ensure your tax records are accurate and well-organized. The authority will have clearer authority to review claims submitted near deadlines, so precision matters.
Simplify your VAT compliance: Take advantage of streamlined self-invoicing rules and simplified error-correction procedures. These changes reduce administrative burden for day-to-day operations, particularly for businesses involved in international trade.
