VAT Calculator
Add or extract Saudi VAT at 15 percent: work the tax up from a net amount, or back it out of a gross amount that already includes it, without the usual error.

How the calculation works
If the amount excludes VAT, the tax = amount x rate. If it already includes VAT, the net = gross divided by (1 + rate) and the difference is the tax. Dividing a VAT-inclusive figure by 1.15 is not the same as taking 15% off it, and confusing the two is the most common invoicing error in contracting.
Frequently asked questions
What is the VAT rate in Saudi Arabia?
15% on taxable goods and services. Returns are filed with the Zakat, Tax and Customs Authority (ZATCA) on the schedule set for your business.
Which value does VAT on a payment certificate apply to?
The value of work executed in the period. Retention is a deduction from the amount paid, not a reduction in the value of the work, and the certificate should show that clearly.
Why is 15% off a gross price not the same as removing VAT?
Because the 15% was added to the smaller net figure. A gross of 115 contains 15 of tax, and 15 is 13.04% of 115 — not 15% of it.
Do I charge VAT on retention released years later?
The tax point follows the supply and the invoicing rules, so agree the treatment with your accountant and current ZATCA guidance rather than assuming the old rate still applies.
