VAT Explained: What It Is, How It Works, and How to Calculate It in 2026
VAT (Value Added Tax) affects every purchase in the UK and EU, yet most people don't fully understand how it works. Here's everything you need to know — including the mistakes that cost businesses thousands.
What Is VAT?
VAT is a consumption tax added to goods and services at each stage of the supply chain. Unlike US sales tax — which is only charged at the final sale — VAT is collected at every step from manufacturer to retailer, with businesses reclaiming the VAT they paid on inputs.
For the end consumer, the practical effect is the same: you pay more for goods and services. But the collection mechanism is fundamentally different.
How to Calculate VAT: Adding and Removing
Example: £100 + 20% VAT = £100 × 1.20 = £120
Removing VAT: Net Price = Gross Price ÷ (1 + rate/100)
Example: £120 ÷ 1.20 = £100 net (£20 VAT)
The most common mistake is calculating 20% of £120 (= £24) to remove VAT. That's wrong. You must divide by 1.20, not subtract 20%.

VAT vs Sales Tax: Key Differences
- Collection point: VAT is collected at every stage; sales tax only at the final sale
- Business reclaim: VAT-registered businesses reclaim input VAT; no equivalent in US sales tax
- Visibility: VAT is usually included in displayed prices in the UK/EU; US sales tax is added at checkout
- Rate: VAT rates are typically higher (15–25%) vs US sales tax (0–13%)
Common VAT Mistakes to Avoid
- Calculating 20% of the gross price to remove VAT — always divide by 1.20
- Forgetting about reduced rates — not all products attract 20%
- Confusing exempt and zero-rated — different treatment for VAT-registered businesses
- Missing VAT registration threshold — UK threshold is £85,000 turnover
