Understanding VAT, GST, and Sales Tax

Value Added Tax (VAT), Goods and Services Tax (GST), and Sales Tax are consumption taxes charged on goods and services. While they serve the same fundamental purpose, they operate differently depending on the country. In the UK, VAT is 20% on most goods and services, 5% on domestic fuel and some home improvements, and 0% on food and children's clothing. In South Africa, VAT is 15%. In Australia, GST is 10%. In Canada, the federal GST rate is 5% with provincial taxes adding further amounts in most provinces.

Adding vs Removing VAT

Adding VAT means you start with a net (exclusive) price and calculate the gross (inclusive) price: Gross = Net × (1 + VAT rate). Removing VAT means you start with a VAT-inclusive price and find the net amount: Net = Gross ÷ (1 + VAT rate). A common mistake is to simply subtract 20% from a VAT-inclusive price — this is incorrect. On a £120 VAT-inclusive price at 20%, the VAT is £20 (not £24), because 20% is calculated on the £100 net, not on the £120 gross.

VAT registration thresholds vary by country. In the UK it's £90,000 annual taxable turnover (2024/25). In South Africa, R1,000,000. In Australia, A$75,000. In Canada, C$30,000. Below these thresholds, registration is optional but can be beneficial if your clients are VAT-registered businesses who can reclaim the tax.

For B2B (business to business) pricing, it's common to quote net/ex-VAT prices since business clients can reclaim VAT. For B2C (consumer) pricing, prices should always be shown inclusive of VAT by law in most countries. When invoicing, always show both the net amount, the VAT amount, and the gross total separately.

Reverse charge VAT applies to certain cross-border business services within the EU and in other jurisdictions. Instead of the supplier charging VAT, the customer accounts for it. If you're invoicing clients in other countries, check whether reverse charge rules apply to your type of service to avoid under or overcharging tax.
