The UAE Federal Tax Authority (FTA) has introduced several updates to the VAT return process for 2026. Whether you’re filing quarterly or annually, understanding the new requirements is essential to avoid penalties and stay compliant.

Key Deadlines for 2026

VAT return filing deadlines in the UAE are tied to your tax period — quarterly or annually depending on your annual revenue. The FTA requires returns to be submitted within 28 days of the end of each tax period.

  • Q1 (January–March): deadline April 28
  • Q2 (April–June): deadline July 28
  • Q3 (July–September): deadline October 28
  • Q4 (October–December): deadline January 28

Companies with annual taxable supplies exceeding AED 150 million are required to file monthly. Confirm your filing frequency with the FTA portal or your tax advisor.

What’s New in 2026

The FTA has updated the VAT return form to include new fields for e-invoicing transactions. Businesses registered under the e-invoicing scheme must ensure their accounting systems export the required structured data format before submission.

Key changes include mandatory digital signatures on all tax invoices above AED 10,000, and a new reconciliation report that must accompany the annual VAT return for large taxpayers.

Common Mistakes and How to Avoid Them

Based on our experience helping UAE companies file VAT returns, these are the most frequent errors that lead to corrections or penalties:

  1. Incorrect Emirates-by-Emirates breakdown. Each emirate’s supplies must be reported separately. Consolidated figures are rejected by the FTA system.
  2. Missing zero-rated export documentation. Zero-rated supplies require supporting export evidence linked directly in the filing.
  3. Input tax claimed on blocked expenses. Entertainment and personal vehicle expenses are not recoverable under UAE VAT law.
  4. Late registration for the new threshold. If your turnover crossed AED 375,000 in the past 12 months, you must register immediately.
