A major wave of UAE tax changes will come into effect on January 1, 2026, reshaping the country’s tax procedures and introducing new rules designed to strengthen clarity, efficiency, and financial discipline. The Ministry of Finance has issued Federal Decree-Law No. (17) of 2025, which amends core provisions of the existing Tax Procedures Law. The updated framework aims to streamline refund processes, refine limitation periods, and enhance the powers of the Federal Tax Authority to ensure a more unified and transparent tax system.
Refund timelines central to UAE tax changes
One of the most significant UAE tax changes is the establishment of a clear five-year limit for taxpayers to request refunds of credit balances or apply those balances against outstanding tax liabilities. The Ministry says this rule increases financial certainty and places predictable structure around tax-related actions. The new framework also includes flexibility. Taxpayers can submit refund requests if a credit arises near the end of the five-year window, or even after it, depending on specific circumstances. This ensures that genuine cases are not excluded due to timing challenges.
FTA powers expand under UAE tax changes
Another core component of the UAE tax changes is the expansion of the Federal Tax Authority’s powers regarding limitation periods. The FTA will now be able to conduct audits or issue assessments even after a limitation period has expired in certain situations, such as when refund requests are filed in the final year. The Authority can also issue binding directions to both taxpayers and its own staff on how tax laws apply to specific transactions. This is expected to reduce inconsistent interpretations and improve overall legal clarity.
Transitional measures support fairness
To prevent disruptions, the UAE tax changes introduce transitional rules for taxpayers whose five-year credit-balance period either expired before January 1, 2026 or will expire within one year of that date. These individuals and businesses will have one year from January 1, 2026 to submit refund requests. They may also file voluntary disclosures up to two years after submitting their request, provided no decision has yet been issued by the FTA.
A stronger, more competitive tax environment
The Ministry of Finance says the updated procedures bring the UAE closer to global tax standards. Officials expect the reforms to increase system efficiency, lower administrative strain, strengthen trust, and support sustainable revenue management. Ultimately, the UAE tax changes are designed to improve the overall business environment and reinforce the country’s long-term economic competitiveness.
