UK VAT rates explained
Value Added Tax (VAT) is a consumption tax applied to most goods and services in the United Kingdom. There are three main VAT rates:
- Standard rate (20%) — applies to most goods and services. This is the default rate used in the calculator above and covers everything from electronics and clothing to professional services and hospitality.
- Reduced rate (5%) — applies to domestic fuel and power, children's car seats, sanitary products and certain home renovation work under the VAT relief scheme.
- Zero rate (0%) — applies to essential items including most food, children's clothing and footwear, books and newspapers, public transport and prescription medicines.
Some items are exempt from VAT entirely (such as insurance, education and healthcare), which means no VAT is charged and the supplier cannot reclaim VAT on related purchases.
— When to add vs remove VAT
Understanding whether you need to add VAT or remove VAT depends entirely on the numbers you are working with.
- Add VAT — use this when you have a net price (excluding VAT) and need to know the gross total the customer should pay. This is the most common scenario for VAT-registered businesses creating invoices or setting selling prices. The formula is: gross = net × (1 + rate/100).
- Remove VAT — use this when you have a gross price (including VAT) and need to extract the underlying net amount. This is useful when analysing supplier invoices, comparing VAT-inclusive prices or preparing VAT returns. The formula is: net = gross / (1 + rate/100).
For example, a £100 net product at 20% VAT gives a £120 gross total (add VAT). A £120 gross receipt at 20% VAT gives a £100 net cost (remove VAT).
VAT registration threshold
The UK VAT registration threshold is £90,000 in taxable turnover over a rolling 12-month period. Key points to be aware of:
- If your VAT taxable turnover exceeds £90,000, you must register for VAT with HMRC.
- Registration is per legal entity, not per business — if you own multiple companies, each is assessed independently.
- You can voluntarily register below the threshold, which allows you to reclaim VAT on business purchases. This can be beneficial if your suppliers charge VAT and you sell to VAT-registered customers.
- Once registered, you must charge VAT on your taxable supplies and submit VAT returns, typically quarterly.
- There are special schemes for small businesses, including the Flat Rate Scheme and Annual Accounting Scheme, which can simplify VAT administration.
The threshold is reviewed by HMRC periodically. Use our take-home pay calculator to understand the wider tax impact on your earnings.
