How to Add VAT to a Price

To add VAT to a net (ex-VAT) amount:

Formula (20% VAT)

Gross = Net Amount × 1.20

Example: Adding VAT

  • Net price: £100
  • VAT (20%): £100 × 0.20 = £20
  • Gross price: £100 + £20 = £120

How to Remove VAT from a Price

To extract VAT from a gross (VAT-inclusive) amount, you divide by 1.20 (for 20% VAT):

Formula (20% VAT)

Net = Gross Amount ÷ 1.20

VAT = Gross - Net

Example: Removing VAT

  • Gross price: £120
  • Net price: £120 ÷ 1.20 = £100
  • VAT amount: £120 - £100 = £20

Common VAT Mistake

Don't just subtract 20% from a gross price! £120 minus 20% = £96, which is wrong. You must divide by 1.20 to get the correct net amount of £100.

VAT Domestic Reverse Charge

The Domestic Reverse Charge applies to construction services supplied between VAT-registered businesses in the UK. It was introduced in March 2021 to combat VAT fraud.

When Does Reverse Charge Apply?

  • You're supplying construction services (not just materials)
  • Your customer is VAT-registered
  • Your customer is not an end user (they're passing it on)
  • The payment is reported under CIS

Reverse Charge Wording

Your invoice must include this statement:

"Reverse Charge: Customer to account for VAT to HMRC"

Making Tax Digital for VAT

All VAT-registered businesses must use Making Tax Digital (MTD) compatible software to keep digital VAT records and submit VAT returns directly to HMRC.

VAT returns are due quarterly, and the deadline is usually one calendar month and 7 days after the end of your VAT period.

VAT Registration Threshold

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