Frequently asked questions
How do I add VAT to a price?
Multiply the net (VAT-exclusive) amount by the VAT rate and add it on. At the 20% standard rate, £100 net becomes £120 gross (£100 × 1.20). This calculator does it instantly.
How do I remove VAT from a price?
Divide the gross (VAT-inclusive) amount by 1 plus the rate. To remove 20% VAT, divide the gross by 1.20 — so £120 gross is £100 net and £20 VAT. Do not simply take 20% off the gross.
What are the UK VAT rates?
The standard rate is 20% (most goods and services). The reduced rate is 5% (e.g. domestic energy, child car seats). The zero rate is 0% (e.g. most food, children’s clothes, books).
Do I need to register for VAT?
You must register for VAT if your taxable turnover exceeds the VAT registration threshold (£90,000) in a rolling 12-month period, or if you expect to exceed it within 30 days. You can also register voluntarily below the threshold.
