Overview of UAE Tax Procedure Amendments Under Cabinet Decision No. 17 of 2026

The UAE Ministry of Finance has introduced amendments through Cabinet Decision No. 17 of 2026, updating key provisions of the Tax Procedures Executive Regulation. The key changes are outlined below:

1. New Record-Keeping Rules for Refund Claims

One of the notable updates regarding the documentation retention period is maintaining the five-year retention rule while introducing a new provision for ongoing refund applications.

New provision: A taxable person must retain books and records for an additional two years if a refund application is under review by the UAE FTA, provided the refund claim was submitted within five years from the end of the relevant tax period.

Jaxa Insights: The updates reinforce the need to keep all supporting refund-related records readily available for audit review until the UAE FTA finalizes its refund assessment.

2. Revised Voluntary Disclosure guidelines:

The Executive Regulation issues clear guidance on the treatment of erroneous refund claims. This updated provision has refined the responsibility of the taxable person while identifying discrepancies in the tax returns or assessments.

Error Reporting Thresholds

• If the error exceeds AED 10,000, then the Voluntary Disclosure must be submitted within 20 business days of identifying the discrepancy.
• If the error is AED 10,000 or less, it might be adjusted in the next eligible tax return or through voluntary disclosure, where no return is available.
• In case no subsequent tax return is required to be filed, the taxpayers must still submit a voluntary disclosure within 20 business days from the date of identifying the error.

Jaxa compliance Note: The revised rules emphasize the need for effective refund control processes, ensuring that taxpayers are advised to promptly detect and correct errors within the regulatory timeline, especially where the AED 10,000 threshold requires mandatory voluntary disclosure.

3. Credit Balance Refund Procedure

The updated regulation replaces the term “ tax refund” with “refund of credit balance” to align with the UAE Tax Procedure law. Article 26 defines the timelines for handling refund applications.

• Statutory timeline for refund decision: The UAE FTA is required to review the refund application and notify the taxpayers of the outcome within 20 business days.
• Refund repayment timeframe: Once the UAE FTA approves the refund, the authority is obligated to process and initiate the repayment within 5 business days from the date of notification.
• Deferred tax return: The UAE FTA may deter or withhold refund payments if the taxpayer has outstanding tax returns that remain unsubmitted.

Jaxa Advisory Note: The term “ refund of credit balance” clarifies that all excess tax amounts are eligible for the scope of refund procedures. To avoid delays, taxpayers are advised to maintain well-documented credit records and timely filing of returns, as outstanding filing or missing records may affect the smooth refund processing.

4. Updated Provisions on Seizure of Documents and Assets

The revised amendments empower FTA to extend the duration for holding seized documents or assets, subject to notifying the concerned party whenever applicable. This enables the authority’s ability to completely review the process.

Jaxa Insights: Businesses are advised to strengthen audit preparedness, ensure document accessibility, and implement backup plans to prepare for possible business disruption arising from a prolonged retention period.

5. Confidential data sharing provision:

The 2026 amendments introduce revised provisions regarding the disclosure of taxpayer information to government authorities, which require formal agreements ensuring proper confidentiality and data protection.

Jaxa Insights: This provision emphasises the need for handling and protecting sensitive business and financial data to reduce regulatory and reputational risk.
