UAE VAT Law Changes 2026: What Business Owners Need to Know About Refund Deadlines and Compliance
The UAE Ministry of Finance has implemented significant amendments to its Value Added Tax Law effective January 1, 2026, tightening compliance rules and clarifying taxpayer rights around refunds and deductions. These changes introduce stricter timelines and stronger anti-evasion measures designed to modernize the tax system while supporting fair business competition.
Key Changes
VAT refund claims now operate under a five-year deadline. This replaces previous rules and applies to both new credits and outstanding balances. More importantly, companies with unclaimed input tax credits from 2018 to 2020 have been granted a one-time transitional window: claims must be submitted by December 31, 2026. After this date, older credits cannot be recovered.
The amendments also strengthen anti-evasion enforcement. The Federal Tax Authority can now deny input tax deductions if they determine the supply forms part of a tax evasion arrangement. Businesses are required to verify the legitimacy and integrity of their suppliers and transactions, shifting some compliance responsibility to taxpayers themselves.
On the positive side, the Ministry emphasized that these reforms aim to reduce administrative burdens, enhance transparency, and improve certainty around tax treatment. The changes are positioned as supporting the UAE's competitiveness as a global business hub while ensuring fair and sustainable government revenues.
What this means
Act now on legacy VAT credits: If your business has unclaimed input tax from 2018–2020, prepare and submit refund requests immediately. The December 31, 2026 deadline is firm—missing it will close these claims permanently.
Strengthen supplier due diligence: Verify that your key suppliers are legitimate and operating transparently. The FTA can deny your input tax deductions retroactively if it determines a supply chain involves evasion, so maintain clear documentation of supplier credentials.
Review your five-year VAT calendar: Plan refund strategies around the new five-year limitation. Set internal reminders for credit expirations to avoid losing valid claims.
