Sales Tax / VAT Calculator
Add tax, remove tax, or find the rate.

Questions about Sales Tax / VAT Calculator
How do I remove VAT from a gross price?
Divide by 1 plus the rate — for 20% VAT, gross / 1.2. Subtracting 20% from the gross is the classic error and gives a number about 4% too low.
Does it know my local rate?
No, and it does not guess. Rates vary by country, by region, by product category and by date; a hardcoded table would be wrong somewhere within a month. Enter the rate that applies to you.
Can I handle an invoice with several rates?
Yes. The line mode lets you enter items at different rates and gives per-rate subtotals plus a document total, which is the layout tax authorities expect on an invoice.
What about zero-rated, exempt or reverse-charge lines?
Enter them at 0% and they total with no tax added, which gives the right arithmetic. What the tool cannot do is tell you which treatment a particular supply attracts — that is a question of law in your jurisdiction, not of percentages.
Can I use it to prepare a VAT return?
For the arithmetic, yes: the per-rate subtotals are the figures a return asks for. It is not accounting software, though. Nothing is saved, there is no audit trail, and it will not tell you what is reclaimable, so copy the numbers into your bookkeeping system.
Is Sales Tax / VAT Calculator really free, with no limits?
Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
Are my files or text uploaded when I use Sales Tax / VAT Calculator?
No. Everything is processed by JavaScript running in your browser, on your device. You can verify it: open your browser's developer tools, switch to the Network tab, and use the tool. You will see no request carrying your data — because there is nowhere for it to go.
