How VAT is calculated

Adding is a multiplication; removing is a division, not a subtraction of the same percentage.

Adding VAT
Net × 1.20 at the standard rate. £1,000 net is £1,200 gross.
Removing VAT
Gross ÷ 1.20. £1,200 gross contains £200 VAT, not £240: taking 20 % off the gross is the common mistake.
Rates
20 % standard; 5 % for domestic energy, children's car seats and some renovations; 0 % for most food, books and children's clothes. Exempt supplies carry no VAT at all.

Frequently asked questions

How do I work out VAT backwards?

Divide the gross by 1.2 to get the net, then subtract to get the VAT. Or multiply the gross by 1/6: £120 gross contains £20 VAT.

When must I register for VAT?

When your taxable turnover passes £90,000 in any 12 months, or will do so within 30 days. Voluntary registration is possible below that.

Which rate applies to my invoice?

Most goods and services are standard-rated at 20 %. Check HMRC's VAT rates list for reduced, zero-rated and exempt items.
