How to Calculate VAT

Value Added Tax (VAT) is a consumption tax charged on most goods and services sold in the UK. The standard rate is 20% and has been at this level since January 2011. Understanding how to add and remove VAT is essential for businesses, freelancers, and anyone checking invoices or receipts.

Adding VAT (Net to Gross)

To add VAT to a net amount, multiply by (1 + VAT rate):

  • 20% VAT: Net amount × 1.20 = Gross amount
  • 5% VAT: Net amount × 1.05 = Gross amount
  • Example: £500 + 20% VAT = £500 × 1.20 = £600 (VAT = £100)

Removing VAT (Gross to Net)

To remove VAT from a gross amount, divide by (1 + VAT rate):

  • 20% VAT: Gross amount ÷ 1.20 = Net amount
  • 5% VAT: Gross amount ÷ 1.05 = Net amount
  • Example: £600 including VAT = £600 ÷ 1.20 = £500 net (VAT = £100)
Common mistake: Do NOT calculate VAT by taking 20% of the gross amount. If a price is £600 including VAT, the VAT is NOT £120. It is £100 (£600 ÷ 1.20 = £500 net; £600 - £500 = £100 VAT). This is a frequent error in business.

VAT Registration Threshold

You must register for VAT with HMRC if your taxable turnover exceeds £90,000 in any rolling 12-month period (or if you expect it to exceed £90,000 in the next 30 days). This threshold was increased from £85,000 to £90,000 from 1 April 2024.

You can also register voluntarily if your turnover is below the threshold. This can be beneficial if you sell mainly to VAT-registered businesses (who can reclaim the VAT) because it lets you reclaim VAT on your own business purchases.

The VAT Flat Rate Scheme

Small businesses with taxable turnover of £150,000 or less can join the Flat Rate Scheme. Instead of tracking VAT on every invoice and purchase, you pay HMRC a fixed percentage of your gross turnover. The percentage depends on your trade sector:

  • Computer and IT consultancy: 14.5%
  • Management consultancy: 14%
  • Hairdressing: 13%
  • Food retailing: 4%
  • Hotels and accommodation: 10.5%
  • Building and construction (labour only): 14.5%

Key VAT Deadlines

  • VAT returns: Usually submitted quarterly. Due 1 month and 7 days after the end of each VAT period.
  • Payment: Same deadline as the return. Set up a direct debit for an extra 3 working days.
  • Making Tax Digital (MTD): All VAT-registered businesses must use compatible software to keep digital records and submit VAT returns.
