VAT Rates in the UK
The UK has a few common VAT rates:
- 20% (Standard rate) – most goods and services
- 5% (Reduced rate) – things like home energy
- 0% (Zero-rated) – food, books, children’s clothes
- Exempt – finance, insurance, education
If you’re unsure which rate applies, it’s worth checking before invoicing. Getting it wrong can cost you later.
How to Calculate VAT (Simple Formula)
You don’t always need a calculator. Here’s the quick method:
To add VAT (20%)
Multiply by 1.20
Example: £100 → £120
To remove VAT (20%)
Divide by 1.20
Example: £120 → £100
A common mistake is subtracting 20%. That gives the wrong answer.

Common VAT Mistakes to Avoid
Even experienced business owners slip up. Watch out for these:
1. Using the wrong VAT rate
Some items don’t fall under 20%. Always double-check.
2. Claiming VAT without a proper invoice
You need a valid VAT invoice, not just a receipt.
3. Mixing personal and business expenses
Only claim VAT on the business portion.
4. Forgetting to register for VAT
If your turnover crosses £90,000, you must register.
Can You Reclaim VAT?
In many cases, yes. You can reclaim VAT on:
- Business expenses
- Equipment purchases
- Professional services
- Some home office costs
But only if you’re VAT registered and have proper records.
When Should You Register for VAT?
You must register if your turnover exceeds £90,000 in a rolling 12 months.
Some businesses register earlier because:
- They want to reclaim VAT
- They work with VAT-registered clients
- It makes them look more established
