Frequently asked questions
How do I remove VAT from a price?
Divide the gross price by (1 + rate). At the UK's 20%, a £120 gross price is £120 ÷ 1.2 = £100 net, so the VAT is £20 — note that it's not 20% of £120.
What are the common VAT rates?
UK: 20% standard, 5% reduced, 0% zero-rated. South Africa: 15%. Philippines: 12%. Nigeria: 7.5%. Ireland: 23%. EU rates vary by country, typically 17–27%.
What's the difference between VAT and GST?
They work the same way — a consumption tax added at each stage with credits for tax already paid. Different countries just use different names (VAT in the UK/EU/ZA, GST in India/Australia/Canada).
