Add or remove VAT at 20%, 5% or a custom rate — net, VAT and gross shown instantly.
The standard UK VAT rate is 20%, with a 5% reduced rate on items such as domestic fuel and children's car seats, and 0% on most food, books and children's clothing. To add VAT, multiply the net price by 1.2; to remove it, divide the gross price by 1.2 — the VAT element of a standard-rated gross price is one sixth. Registration is compulsory once taxable turnover passes £90,000 in any rolling 12 months.

| Rate | What it applies to | Examples |
|---|---|---|
| 20% Standard | Most goods and services | Electronics, clothing (adult), restaurant meals, professional services, haircuts, alcohol, vehicles |
| 5% Reduced | Specific categories by law | Domestic fuel & power (gas, electricity), children's car seats, mobility aids, smoking cessation products, sanitary products, residential property conversions |
| 0% Zero-rated | Essential goods and services | Most food (not hot food/restaurant), children's clothing & footwear, books & newspapers, prescriptions, public transport (buses, trains, flights), new residential buildings |
| Exempt | Outside the VAT system | Insurance, banking & finance, private education, healthcare, betting & gaming, postage stamps, burial & cremation |
Zero-rated and exempt are not the same — see the FAQ below for the key difference.
The fastest mental arithmetic shortcuts:
| Rate | Add VAT to net | Remove VAT from gross | Find VAT in gross |
|---|---|---|---|
| 20% | Multiply by 1.2 | Divide by 1.2 | Divide gross by 6 |
| 5% | Multiply by 1.05 | Divide by 1.05 | Divide gross by 21 |
| 0% | No change | No change | Zero |
Example: A gross invoice is £1,200 including 20% VAT. The VAT element = £1,200 ÷ 6 = £200. Net = £1,200 − £200 = £1,000.
Businesses must register for VAT when their taxable turnover exceeds £90,000 in any rolling 12-month period (raised from £85,000 in April 2024). Once registered, the business must:
Voluntary registration below the threshold is possible and may be beneficial if the business has significant VAT-bearing expenses — it allows reclaiming input tax. Registration is also required immediately (regardless of turnover) if you expect to exceed the threshold in the next 30 days alone.
A valid VAT invoice must include: your VAT registration number, the supply date, a description of the goods or services, the net amount, the VAT rate applied and the VAT amount. If you supply to other VAT-registered businesses, they can reclaim the VAT you charge them — so quoting prices exclusive of VAT (net) is standard practice in B2B contexts. Consumer-facing businesses typically quote prices inclusive of VAT (gross).
