Value Added Tax (VAT) is a consumption tax charged on most goods and services sold by registered businesses in the UK. If your business turnover exceeds the VAT registration threshold of £90,000, registering for VAT is mandatory. This calculator helps business owners, freelancers, and consumers quickly add VAT to a price or extract it from a gross total.

To calculate VAT, you must apply the correct rate. Under HMRC rules, there are three main rate bands: standard rate (20%), reduced rate (5%), and zero rate (0%). Use the selector above to toggle rates or enter a custom rate.

⚙️ UK VAT Rates and Rules

HMRC classifies goods and services under different rates depending on their category:

  • Standard Rate (20%): Applies to the majority of goods and services, including electronics, professional services, vehicles, and adult clothing.
  • Reduced Rate (5%): Applies to a limited group of items, such as domestic energy (heating fuel and electricity), children’s car seats, mobility aids, and certain renovations.
  • Zero Rate (0%): Applied to goods that are still VAT taxable but charged at 0%. This includes most supermarket food, children’s clothes, books, newspapers, and public transport.

📊 Practical Examples of VAT Calculations

Here are two clear examples demonstrating how to add and remove VAT:

Example 1: Adding 20% Standard VAT (Net to Gross)
  • Net cost: **£100.00**
  • VAT rate: **20%**

Calculation: £100.00 × 0.20 = £20.00 VAT.

Total Gross Amount: **£120.00**
Example 2: Removing 20% Standard VAT (Gross to Net)
  • Gross cost: **£120.00**
  • VAT rate: **20%**

Calculation: £120.00 ÷ 1.20 = £100.00 Net.

Total Net Amount: **£100.00** (VAT portion: **£20.00**)

📑 Common Pitfalls to Avoid

  1. Incorrectly subtracting 20% to remove VAT: If you subtract 20% directly from a gross price of £120.00, you get £96.00, which is incorrect. You must divide by 1.20 to extract the correct net price of £100.00.
  2. Confusing Zero-Rated with Exempt Goods: Zero-rated goods count toward your VAT taxable turnover, whereas exempt goods (such as health services, insurance, and education) do not.
  3. Missing the Registration Threshold: If your rolling 12-month VAT taxable turnover goes over £90,000, you have 30 days to register with HMRC to avoid penalties.

❓ Frequently Asked Questions (FAQ)

Zero-rated goods are taxable at 0% VAT, meaning registered businesses can reclaim VAT on inputs. Exempt goods are not taxable, so businesses cannot reclaim VAT on associated purchases.

To add standard 20% VAT, multiply your net price by 0.2 to find the VAT portion, then add it to the original net price. Or multiply the net price by 1.2 to find the total gross price directly.

To remove standard 20% VAT, divide the total gross price by 1.2. The result is the net price. Subtract the net price from the gross price to find the exact VAT amount charged.

The UK VAT registration threshold is £90,000. If your taxable turnover over a rolling 12-month period exceeds this amount, you must register for VAT with HMRC.
