Frequently asked questions
How do I add VAT to a price?
Multiply the price before tax by 1 plus the rate divided by 100. With a 20 % rate, 100 becomes 100 × 1.2 = 120, of which 20 is VAT.
How do I remove VAT from a price that includes it?
Divide the price by 1 plus the rate divided by 100. With a 20 % rate, 120 ÷ 1.2 = 100, so the VAT is 20. Taking 20 % off 120 would give 96, which is wrong: the 20 % was calculated on 100, not on 120.
Why do some countries have several VAT rates?
The standard rate applies to most goods and services. Reduced rates apply to specific categories that each country defines, such as food, books, medicines or public transport. Your tax authority lists which rate applies to what you sell.
Are the rates up to date?
They are the rates in force in October 2026. Governments change them in their budgets, so check the official source before issuing an invoice. You can always type any rate with “Other”.
What is the difference between VAT, GST and sales tax?
VAT and GST work the same way: a tax on consumption collected at each step of the supply chain, where businesses deduct the tax they have paid. GST is the name used in countries such as Australia, New Zealand, Singapore, India and Canada. A sales tax, as in the United States, is charged once at the final sale and its rate depends on the state and city, which is why it isn’t listed here.
How are the amounts rounded?
To the smallest unit of the currency, such as the cent, or the whole yen. The tax is rounded first, then added to or taken from the amount, so the three figures always add up. Some invoicing systems round per line rather than on the total, which can make a difference of one cent.
