United Arab Emirates has amended the executive regulation governing tax procedures, sharpening rules on voluntary disclosures, tax refunds, record retention and the handling of taxpayer information as the country deepens a broader overhaul of its fiscal framework. The Ministry of Finance said the changes to Cabinet Decision No. 74 of 2023 took effect on 1 April 2026 and were introduced to align the regulation with amendments to the Tax Procedures Law that came into force on 1 January 2026.
At the centre of the new package is a clearer set of procedures for taxpayers making voluntary disclosures, a mechanism used to correct errors or omissions in returns. The updated regulation also states that refund procedures apply to any credit balance in favour of the taxpayer, a move that gives companies and individuals a more explicit route for recovering overpaid tax or unused balances held with the Federal Tax Authority.
The changes go beyond disclosures and refunds. The amended rules revise how taxpayer information may be disclosed to competent government authorities, while maintaining confidentiality protections and defining the scope and limits of data use. They also extend the period for retaining records by an additional two years for tax periods linked to refund claims filed before the statute of limitations expires where the authority has not yet reached a decision. In parallel, the regulation now allows for a longer period for preserving or seizing documents or assets for tax audit and examination purposes.
Taken together, the latest executive-regulation changes build on the Ministry of Finance’s November 2025 amendments to the Tax Procedures Law, which introduced stricter timelines and wider procedural powers. Under those earlier changes, taxpayers were given no more than five years from the end of the relevant tax period to request a refund of a credit balance or use it to settle tax liabilities. The ministry also created transitional relief for older balances, allowing some taxpayers whose five-year period had already expired, or was due to expire within a year from 1 January 2026, to file refund requests by 31 December 2026.
That chronology matters because the 1 April regulation changes appear designed to make the legal plumbing match the law already in force. By clarifying the administrative steps around voluntary disclosure and refunds, the government is reducing ambiguity at a time when the tax system is expanding in scale and complexity. Corporate tax has been layered onto a framework that already included VAT and excise tax, while the authorities are also preparing the ground for electronic invoicing, another change likely to increase the amount of transaction-level data available to regulators.
For businesses, the practical message is twofold. First, unused tax credits can no longer be treated as balances that sit indefinitely without action. Second, record keeping and internal controls will matter even more where a refund claim is involved or where a filing error may later need correction through a voluntary disclosure. Firms with ageing VAT or other tax balances may now face stronger pressure to review historic positions, document claims carefully and ensure records remain available for longer where disputes or determinations are still pending.
The data-confidentiality provisions are also significant. As tax administrations globally seek more information sharing and greater digital visibility, authorities have had to balance enforcement with safeguards around taxpayer information. The UAE amendments attempt to do both by revising the mechanisms for disclosure to government bodies while reaffirming that confidential information remains protected and that its use is limited. For multinational businesses and advisers, that balance is likely to be watched closely as compliance systems become more digital and more integrated across tax types.
Policy-wise, the amendments fit the UAE’s wider effort to present itself as a rules-based, investment-friendly jurisdiction that can impose taxes without undermining competitiveness. The ministry has framed the changes as part of a drive to improve transparency, strengthen compliance and safeguard taxpayer rights, while outside legal and tax specialists have interpreted the earlier law amendments as an attempt to unify procedures across the tax system and reduce inconsistent treatment of similar cases.
