How VAT works in the UK

The standard rate of UK VAT is 20 percent, and it applies to most goods and services. To add VAT, multiply by 1.20: 100 becomes 120. To take it out, divide a VAT-inclusive total by 1.20: 120 contains 20 of VAT.

A reduced rate of 5 percent applies to some goods and services, and some supplies are zero-rated at 0 percent. Check GOV.UK for the rate that applies to your job: some building work, such as certain new-build housing or energy-saving installations, is reduced-rated or zero-rated. Zero-rated and exempt are different: neither has VAT added for the customer, but exempt supplies sit outside the VAT system, so ask HMRC how your work is classed.

Common questions

How do I calculate VAT at 20 percent?

Multiply the price before VAT by 0.20 to get the VAT, or by 1.20 to get the price including VAT. To work backwards, divide a VAT-inclusive total by 6 to find the VAT in it.

Which VAT rate do I charge?

Use the standard rate of 20 percent unless the goods or services are reduced-rated at 5 percent or zero-rated. GOV.UK lists which is which. Only VAT-registered businesses charge VAT.
