What is VAT?

Value Added Tax (VAT) is a consumption tax applied to most goods and services in the UK. The standard VAT rate is 20%, with other reduced rates for specific items such as energy (5%) or essential goods (0%).

Every business that is VAT-registered must charge VAT on its sales and can reclaim VAT on purchases.

How to Calculate VAT

Here are the exact formulas used for UK VAT calculations.

Add VAT (Net → Gross)
Gross = Net × (1 + VAT Rate)
Remove VAT (Gross → Net)
Net = Gross ÷ (1 + VAT Rate)

Example (20% VAT):

  • £100 + 20% VAT = £120
  • £120 minus VAT = £100
