Submit VAT returns online to the FTA at each tax period's end, detailing your taxable supplies and VAT due. Quarterly returns are due by the 28th of the following month; late submissions incur AED 1,000 penalty initially, then AED 2,000 for subsequent delays. Late payments attract a 2% penalty for the first 7 days, increasing to 4%, and 1% daily after a month, up to 300% of the due VAT. Zero-rated supplies also require VAT returns, subject to late penalties. VAT payments can be made online via the FTA website using credit card, eDebit, or bank transfer, ensuring timely and flexible payment options.
