How do I remove VAT from a price?+

Divide the price including VAT by 1.2 for 20% VAT (or by 1.05 for 5%). For example, £120 ÷ 1.2 = £100, so the VAT is £20.

What is the VAT registration threshold?+

£90,000 of taxable turnover in any rolling 12-month period, since 1 April 2024. You can also register voluntarily below that.
