What is the standard Saudi VAT rate?
The standard rate is 15%. Some supplies are zero-rated or exempt. Confirm the treatment for your supply in official ZATCA guidance.
How do I add 15% VAT?
VAT = net × 0.15. Gross = net × 1.15. Example: SAR 1,000 net → SAR 150 VAT → SAR 1,150 gross.
How do I extract VAT from an inclusive amount?
Net = gross ÷ 1.15. VAT = gross − net. Example: SAR 1,150 inclusive → SAR 1,000 net and SAR 150 VAT.
