The formulas
To add tax, multiply the net price by one plus the rate: at 20% VAT, 100 becomes 100 × 1.2 = 120. To remove tax from a price that includes it, divide by the same factor: 120 ÷ 1.2 = 100. A very common mistake is to subtract 20% from the gross price, which gives 96 instead of 100, because the tax was calculated on the smaller net amount. At 20%, the VAT is always one sixth of the gross price.
VAT (value added tax) and GST (goods and services tax) work the same way: businesses charge it on sales, reclaim it on purchases and pay the difference to the tax authority. US sales tax is different: it is usually added only at the final sale, and rates combine state, county and city taxes, so enter the total rate for the place of sale. The country rates listed are standard rates, checked on 21 October 2026: for the EU against each member state's tax authority, which supply the European Commission's Taxes in Europe Database (for example Estonia 24% since 1 July 2025, Slovakia 23% since 1 January 2025, Romania 21% since 1 August 2025, Finland 25.5% since 1 September 2024, Luxembourg 17% since 1 January 2024 and Croatia 25%). Many countries also have reduced rates for food, books, energy or children's goods, and rates change, so check your tax authority for the latest figures. Amounts are rounded to two decimal places per line, as on most invoices.
How do I remove 20% VAT from a price?
Divide by 1.2. For example, 60 including VAT is 50 before VAT, and the VAT is 10.
What is the UK VAT rate?
The standard rate is 20%, with a reduced rate of 5% (for example home energy) and a zero rate for most food and children's clothes.
Is GST calculated the same way as VAT?
Yes. Australian GST is 10%, so multiply by 1.1 to add it and divide by 1.1 to remove it.
