How to use this Saudi VAT calculator
1
Choose your calculation mode
Use Add VAT when you have a price before tax and need the final billable amount. Use Remove VAT when you have a VAT-inclusive figure — such as a total on a supplier invoice — and need to know the underlying cost. Use Multi-Item Invoice when preparing a quotation with several materials or services that need one combined VAT total.

Enter the amount in Saudi Riyals
Type the figure into the field — the calculator assumes Saudi Riyals (SAR) throughout. For a single amount, enter it directly. For a multi-item invoice, add a description and amount for each line; the calculator keeps a running subtotal as you go, so you can see the total build up in real time.
Currency: SAR
Decimals supported
3
Select the correct VAT rate
Most construction goods and services in Saudi Arabia fall under the 15% standard rate. Select 0% zero-rated / exempt only for specific categories such as qualifying exports outside the GCC, or supplies that ZATCA has explicitly classified as zero-rated or exempt — check your specific transaction against ZATCA guidance if you are unsure.
15% → most goods & services
0% → exports, specific exemptions

Read the results breakdown
The results panel shows the amount excluding VAT, the VAT amount itself, and the total including VAT — every figure a Saudi tax invoice is required to display separately. The highlighted row is the figure you were solving for: the total when adding VAT, or the base amount when removing it.

Carry the figures onto your invoice or quotation
A ZATCA-compliant tax invoice must show the amount before VAT, the VAT rate applied, the VAT amount, and the total separately — not just a single combined figure. Use the three results together when drafting your invoice or client quotation, rather than quoting the total alone.

ZATCA Compliance Tips
What contractors often get wrong
VAT must be shown separately, not rolled in
A tax invoice quoting only a lump total without the base amount, rate, and VAT figure shown individually does not meet ZATCA's e-invoicing format requirements.
Registration is mandatory above SAR 375,000
Businesses with annual taxable supplies over SAR 375,000 must register for VAT. Voluntary registration is available from SAR 187,500.
Watch for reverse charge on imported services
Services bought from a supplier outside Saudi Arabia are often subject to the reverse charge mechanism — the buyer, not the seller, accounts for the VAT.
Keep VAT records for at least 6 years
ZATCA requires invoices, credit notes, and supporting VAT records to be retained for a minimum of six years — longer for real-estate related transactions.
★ Pro tip
Log every quotation and invoice VAT calculation in Onsite. Line items, VAT amounts, and totals stay linked to the project BOQ automatically — no re-entering figures when it's time to raise the real ZATCA-compliant invoice.
Common zero-rated / exempt cases
| Category | Note |
|---|---|
| Exports | Goods shipped outside GCC territory |
| Int'l transport | Qualifying international freight & passenger transport |
| Financial services | Certain margin-based financial services |
| Residential lease | Exempt in most cases, not zero-rated |

Stop calculating VAT manually
on every invoice and quotation
Onsite generates ZATCA-aligned VAT breakdowns automatically on every client invoice and vendor bill — linked to your BOQ, so the numbers never need re-entering by hand.
