Frequently Asked Questions
What is the current standard UK VAT rate?
The standard UK VAT rate is 20%, applicable to most goods and services. There is also a reduced rate of 5% for items such as domestic fuel and children's car seats, and a zero rate (0%) for essentials like food and children's clothing.
How do I calculate VAT in the UK?
To add 20% VAT to a net price, multiply the net amount by 1.20. To find the VAT amount alone, multiply by 0.20. For example, a £500 net invoice becomes £600 gross, with £100 VAT.
How do I reverse calculate (remove) VAT from a gross price?
To remove 20% VAT from a gross price, divide by 1.20. For example, a £600 gross price ÷ 1.20 = £500 net. This is also called "backing out" or "stripping" the VAT.
Do I need to register for VAT?
You must register for VAT if your taxable turnover exceeds the current VAT threshold (£90,000 as of 2024/25). You can also register voluntarily below this threshold, which may be beneficial if you have significant VATable input costs.
What is the difference between zero-rated and VAT-exempt?
Zero-rated goods/services are VATable at 0%, meaning businesses can still reclaim input VAT on related purchases. VAT-exempt supplies are outside the VAT system entirely — businesses cannot reclaim input VAT on costs related to exempt supplies.
