VAT vs Sales Tax: What Is the Difference and Which Applies to You?

The core difference

Sales tax is simple: the final retailer charges tax on the sale and remits it to the government. Nothing is charged or reclaimed at earlier stages of the supply chain. VAT is more complex: tax is charged at every stage from raw material to end consumer, but each business in the chain reclaims the VAT it paid on its purchases (input tax) against the VAT it charged on its sales (output tax). Only the net amount - the VAT on the value added at each stage - is paid to the government. The economic effect is the same: the end consumer bears the full tax. The administrative difference is significant.

How VAT works - a worked example

A manufacturer makes a product for 100 and sells it to a distributor for 200, charging 20% VAT. The invoice shows: net 200, VAT 40, total 240. The manufacturer collects 40 in VAT and remits it to the government. The distributor sells to a retailer for 300, charging 20% VAT: net 300, VAT 60, total 360. The distributor collected 60, already paid 40, so remits the difference: 20. The retailer sells to the consumer for 500, charging 20% VAT: net 500, VAT 100, total 600. The retailer collected 100, already paid 60, remits 40. Total VAT collected by government: 40 + 20 + 40 = 100 - exactly 20% of the final consumer price of 500.

How sales tax works - a worked example

Using the same supply chain with a 10% sales tax: the manufacturer sells to the distributor for 200 with no tax. The distributor sells to the retailer for 300 with no tax. The retailer sells to the consumer for 500 and charges 10% sales tax: total 550. The retailer remits 50 to the state. The government collects 50 in total - 10% of the final retail price. No other party in the chain paid or reclaimed any tax.

In the US, sales tax rates and rules vary by state and sometimes by county and city. A product may be taxable in one state and exempt in another. Remote sellers above certain revenue thresholds (typically 100,000 in sales or 200 transactions per state, post-South Dakota v. Wayfair 2018) must collect and remit sales tax for each state where they have customers - a major administrative burden for e-commerce businesses.

Which countries use which system

VAT (or its close equivalent, GST - Goods and Services Tax) is used by most of the world: all EU member states, the UK, Australia, Canada, India, Japan, and over 160 countries in total. The US is the major exception - it uses a state-level sales tax system with no federal equivalent. Standard VAT rates range from 5% in Canada (federal GST) to 27% in Hungary, with the EU average around 21%. UK VAT is 20%. Australian GST is 10%.

For businesses: what you need to know

If you sell to customers in a VAT country and you exceed the local registration threshold (in the UK, 90,000 in rolling 12-month turnover as of 2024-25), you must register for VAT, charge it on sales, and file regular returns. Once registered, you reclaim the VAT you pay on business purchases - which can be a significant cash benefit for businesses with high input costs.

For digital products sold cross-border within the EU, the rules changed in 2021: sellers must charge VAT at the buyer's local rate regardless of where the seller is based. Selling a 20 digital product to a German customer means charging 19% German VAT, not UK VAT. The EU's OSS (One Stop Shop) scheme allows sellers to register in one EU country and file a single return for all EU sales.

Common mistakes

• Adding VAT on top of a price that already includes it - always clarify whether a quoted price is ex-VAT (net) or inc-VAT (gross). 'Plus VAT' and 'inclusive of VAT' are very different numbers.
• Ignoring VAT registration thresholds - if your turnover crosses the threshold, registration becomes mandatory. Late registration penalties can include back-payment of all VAT due since the threshold was crossed.
• Assuming digital products are VAT-exempt abroad - most countries apply VAT or equivalent to digital services sold to their residents, even from foreign businesses.
• Confusing VAT rate between categories - in the UK, most goods are 20% standard rate but food, children's clothing, and books are 0%. Charging the wrong rate is a compliance error.
