Follow a transparent method to calculate 5% UAE VAT, including discounts and invoice totals.
VAT-exclusive pricing
For a standard-rated amount of AED 1,000 excluding VAT, multiply by 5% to obtain AED 50 VAT. The VAT-inclusive total is AED 1,050. Keep the net amount, VAT amount and gross amount separate in the invoice summary.
Discounts and line items
Apply the commercial discount according to the transaction terms before calculating VAT on the resulting taxable amount. Use a consistent rounding method at the line or invoice level and ensure the displayed VAT amounts add to the summary. Different systems can produce a one-fils difference if they round at different stages.
Classification comes first
Arithmetic is only the last step. Confirm whether the supply is standard-rated, zero-rated, exempt or outside scope. A 5% calculator cannot decide that classification.
