Free Sales Tax & VAT Calculator

Add Tax vs Remove Tax

Add Tax: Use when you know the price before tax and need the final price. Common for quoting, invoicing, and pricing.

Remove Tax: Use when you have a receipt total and need to figure out how much of it was tax — common for expense reports and bookkeeping. Formula: net = gross / (1 + rate).

Frequently asked questions

What's the difference between adding and removing tax?

Add Tax: you have the pre-tax price and need to know the final price. Remove Tax: you have the final receipt total and want to extract how much of it was tax (reverse / inclusive calculation).

Does this support VAT and GST?

Yes. Sales tax, VAT (Europe, UK), GST (Australia, India, Canada), and HST all use the same percentage math. Enter your local rate.

Why is the removed-tax amount smaller than rate × gross?

Because the rate applies to the net amount, not the gross. A 20% VAT on a £120 receipt means £100 net + £20 tax — the tax is 16.67% of the gross, not 20%.
