What Is VAT?
VAT (Value Added Tax) is a consumption tax applied to goods and services at each stage of production and distribution. Unlike sales tax which is collected only at the final point of sale, VAT is collected incrementally, with businesses paying tax on the value they add and reclaiming VAT paid on inputs.
VAT is used in over 160 countries worldwide, with rates varying from 5% (e.g., Japan, Canada GST) to 27% (Hungary). The European Union mandates VAT for all member states with a minimum standard rate of 15%. In pricing, amounts can be either tax-exclusive (net) or tax-inclusive (gross).
How VAT Calculations Work
VAT calculations involve two directions: adding VAT to a net price, or removing VAT from a gross price. The formulas are straightforward but easy to confuse, especially when working across different countries with different rates.
- Add VAT — Gross = Net x (1 + Rate/100). For a net price of 100 EUR at 20% VAT: 100 x 1.20 = 120 EUR gross
- Remove VAT — Net = Gross / (1 + Rate/100). For a gross price of 120 EUR at 20% VAT: 120 / 1.20 = 100 EUR net
- Extract VAT amount — VAT = Gross - Net, or equivalently VAT = Gross x (Rate / (100 + Rate)). From 120 EUR gross at 20%: 120 x (20/120) = 20 EUR VAT

Frequently Asked Questions
What is the difference between VAT and sales tax?
VAT is collected at every stage of the supply chain, with each business paying tax only on the value it adds (output VAT minus input VAT). Sales tax is collected once at the final retail sale. VAT is self-enforcing because each buyer has an incentive to ensure their supplier charges VAT correctly. Most countries outside the US use VAT.
Should I display prices with or without VAT?
In the EU, B2C prices must include VAT (tax-inclusive). B2B prices are typically shown without VAT since businesses reclaim input VAT. In the US, prices are usually shown without sales tax. For international e-commerce, show tax-inclusive prices with a note about the applicable rate, and calculate the exact tax at checkout.
What are reduced and zero VAT rates?
Many countries apply reduced rates (5-10%) to essential items like food, medicine, books, and children's clothing. Zero-rated goods (0% VAT) include exports and certain essential supplies — the business can still reclaim input VAT. Exempt goods are not subject to VAT at all, and input VAT cannot be reclaimed.
