VAT Filing in 2026
VAT remains an important part of the UAE’s tax system. VAT-registered businesses must submit their VAT returns and pay any VAT due according to the Tax Period assigned to them by the Federal Tax Authority.
VAT Return Filing
The FTA assigns a Tax Period to each VAT registrant. Depending on the registration and circumstances, this may be a monthly, quarterly or other approved Tax Period.
VAT returns and any related VAT payments are generally due within 28 days after the end of the relevant Tax Period.
Important: These dates are illustrative. Your actual VAT Tax Period and due date are determined by the FTA and should be confirmed through your EmaraTax account.
VAT Payment Deadlines
In addition to submitting VAT returns, businesses in the UAE are required to settle their VAT payments by the due date. Late payments can result in significant penalties based on number of days delayed. A 2% penalty is applied immediately after the due date on the unpaid amount, followed by an additional 4% if the payment remains unpaid after seven days. If the delay continues, a 1% daily penalty is charged starting one month after the due date, up to a maximum of 300% of the unpaid tax.

Here are some extra tips to get the most out of the tax calendar
- Create reminders: Utilize computer programs to create reminders for important filing deadlines so nothing falls through the cracks.
