Uses standard UK VAT rates. Some goods and services are reduced-rated, zero-rated or exempt — we’ll make sure your VAT returns apply the right treatment.
Whether you’re raising an invoice, checking a receipt or pricing up a job, this free UK VAT calculator does the maths for you. Add VAT to a net figure or strip VAT out of a gross figure at the standard 20% rate, the reduced 5% rate, or 0% — and see the net, VAT and gross side by side. Built by accountants, so the numbers are always right, and ready when you need your VAT returns handled too.
UK VAT rates explained
Most things are charged at the standard 20% rate, but some are charged less — or nothing at all.
| Rate | Typically applies to |
|---|---|
| Standard — 20% | Most goods and services |
| Reduced — 5% | Domestic energy, children’s car seats, some mobility aids |
| Zero — 0% | Most food, children’s clothing, books and newspapers |
| Exempt | Insurance, postage stamps, most education and health services |
“Exempt” isn’t the same as zero-rated — you can’t reclaim the VAT on costs linked to exempt sales. We make sure your returns apply the right treatment to every line.
When do I need to register for VAT?
You must register for VAT with HMRC once your VAT-taxable turnover passes £90,000 in any rolling 12-month period — or if you expect to within the next 30 days. You can also register voluntarily, which can pay off when your customers are themselves VAT-registered.
Once registered, you charge VAT on your sales (output VAT), reclaim the VAT on your purchases (input VAT), and file Making Tax Digital returns — usually each quarter — to HMRC.
Smaller businesses can sometimes save with the VAT Flat Rate Scheme, paying a fixed percentage of turnover instead of tracking the VAT on every transaction. We’ll check whether it would cut your bill.
