The UAE Ministry of Finance has introduced major tax rule changes taking effect from January 1, 2026, under Federal Decree-Law No. 17 of 2025. These amendments mark a significant shift in the UAE’s tax framework, designed to boost transparency, strengthen compliance, and align with global tax standards.
1. Clear Five-Year Deadline for Tax Refunds
One of the most impactful amendments is the establishment of a fixed five-year time frame for claiming refunds of tax credit balances or using them to offset future liabilities. Previously, the UAE had no statutory deadline, which created uncertainty in financial planning.
What This Means:
- Businesses registered for VAT, corporate tax, and excise must claim refunds within five years of the end of the tax period.
- It is critical to note that any overdue refund claims will now expire permanently.
- Transitional relief exists: if the refund period ends before January 1, 2026, taxpayers have until January 1, 2027, to file their claims.
Why This Matters:
This reform promotes financial predictability and encourages timely compliance across VAT, corporate tax, and excise tax regimes.
2. Expanded Audit Powers for the Federal Tax Authority (FTA)
The amendments grant the FTA broader powers to conduct audits and issue assessments in specific circumstances-even after the typical limitation period has expired.
Key Takeaways:
- FTA can audit transactions linked to refunds filed within the five-year expiry window.
- Enhanced oversight helps reduce tax disputes and strengthens enforcement.
Business Insight:
Companies should prepare accurate documentation and maintain robust compliance systems as audit intensity increases.
3. Binding Interpretations to Reduce Disputes
A major structural reform now empowers the Federal Tax Authority (FTA) to issue official, binding guidance on the application of specific tax provisions. These directions are mandatory for both taxpayers and the FTA, ensuring uniform implementation of the law.
This development resolves long-standing business concerns about inconsistent interpretations of tax legislation. With binding guidance in place, businesses can plan with greater certainty, minimise compliance disputes, and reduce potential legal risks.
Benefits:
- Reduces inconsistencies in interpretation across businesses.
- Improves legal certainty for taxpayers.
Impact for Businesses:
Clear administrative guidance helps CFOs and tax teams plan long-term strategies with confidence.
4. Why the 2026 Tax Amendments Matter
The 2026 changes are not merely technical updates-they represent a maturing tax ecosystem that benefits the UAE’s investment climate:
- Increased certainty for businesses and investors
- Stronger compliance standards aligned with global norms
- Enhanced transparency in tax administration
- Reduced disputes through binding guidance
- Greater financial planning clarity through time limits
In essence, the UAE is signaling that it not only attracts global business but also ensures a fair and efficient tax environment.
Action Steps for Businesses for 2026
To prepare for the new tax landscape:
- Review all tax credit balances and plan refund claims within the new time limits.
- Enhance audit readiness with thorough documentation and compliance checks.
- Upgrade finance systems to support e-invoicing and new reporting standards.
- Educate finance teams on the implications of binding administrative guidance.
Frequently Asked Questions
What becomes of unclaimed VAT credits after five years?
Ans. VAT credits permanently lapse five years from the date the input tax was incurred. Once expired, these credits cannot be reclaimed or refunded under any circumstances. To avoid losing eligibility, refund claims should be submitted well in advance of the deadline to allow sufficient time for FTA review and any follow-up queries.
Is there a distinct regulatory framework for free zone companies?
Ans. The five-year refund limitation and input tax recovery rules apply uniformly to all UAE businesses, irrespective of their location.
Should minor VAT refund amounts still be claimed?
Ans. Yes, if you hold valid VAT credits nearing their expiry, it is advisable to file a refund claim. Even modest amounts constitute recoverable cash to which you are legally entitled. With significant improvements to the FTA’s online portal, the administrative burden has been greatly reduced, making it practical to pursue refund claims of any meaningful value.
