How to add and remove VAT

Adding VAT at 20%: gross = net × 1.20 Removing VAT at 20%: net = gross ÷ 1.20 VAT inside a gross price at 20% = gross ÷ 6 VAT inside a gross price at 5% = gross ÷ 21

The last two lines are the VAT fractions. At 20% the VAT is 20 parts out of 120, which is one sixth of the gross price. At 5% it is 5 parts out of 105, which is one twenty-first.

Worked examples

Adding VAT. A net price of £100.00 at the standard rate has £20.00 of VAT, so the gross price is £120.00.

Removing VAT. A shelf price of £99.99 including 20% VAT is £83.33 net, with £16.66 of VAT.

Do I need to charge VAT?

GOV.UK says you must register for VAT if your total taxable turnover for the last 12 months goes over £90,000, or if you expect it to go over that in the next 30 days. This page does not cover VAT schemes or special cases. Check GOV.UK or ask an accountant.
