A value-added tax, or VAT, is a consumption tax collected in slices at every stage of production and distribution, from raw materials through to the retail shelf. Each business in the chain charges VAT on what it sells, subtracts the VAT it paid to its own suppliers, and sends the difference to the government. The final consumer pays the full tax embedded in the retail price with no way to reclaim it. Roughly 175 countries use this system, which makes it the most common form of consumption tax in the world. The United States is the only major economy without one at the federal level, relying instead on state and local sales taxes.1Tax Foundation. VAT Rates in Europe, 20262Congressional Budget Office.

How the Tax Is Collected Stage by Stage
VAT works through two numbers on every business’s books. Output tax is what the business charges its customers. Input tax is what it paid its suppliers. At the end of the filing period, the business subtracts input tax from output tax and remits the difference.3European Commission. How Does VAT Work?
A short example at a 20 percent rate makes it concrete. An iron ore mine buys €200 of helmets and pays €40 in VAT on that purchase. It later sells €1,000 of ore to a smelter and collects €200 in VAT. The mine deducts the €40 it already paid from the €200 it collected and sends €160 to the treasury. The smelter does the same thing on its own sales, deducting the €200 it paid the mine from whatever it collects from its buyer. Every link in the chain works this way, so the tax never compounds on itself.3European Commission. How Does VAT Work?
When a business’s input tax exceeds its output tax in a given period, most countries refund the excess or let the business carry it forward as a credit. That situation shows up often for exporters, whose foreign sales are typically zero-rated while they keep paying VAT on domestic purchases.4European Commission. Deductions
Who Actually Pays
Businesses handle the collection and paperwork, but they do not carry the cost. Every business in the supply chain offsets the VAT it paid through input credits, so the tax passes cleanly through to the next buyer. The one buyer who cannot claim a credit is the person at the end of the line: the retail consumer. Economic analysis and evidence agree that VAT is passed along in higher retail prices, which means the final shopper ends up paying the full amount.5Tax Policy Center. Who Would Bear the Burden of a VAT?
How VAT Compares to U.S. Sales Tax
For American readers, the useful comparison is between VAT and the state and local retail sales taxes they already know. Both are consumption taxes and both fall on the buyer in the end, but they run on different plumbing.
A retail sales tax is collected only once, at the final sale to the consumer. VAT is collected at every stage, with each business remitting only what it owes on the value it added. That has real consequences for business-to-business purchases. Under VAT, the credit-invoice system automatically strips tax out of intermediate sales. Under a sales tax, businesses have to present exemption certificates to buy inputs without tax; when that process breaks down, tax stacks on top of tax by the time a product reaches the consumer.
The credit-invoice mechanism also builds in a degree of self-policing. A buyer that wants to claim an input credit needs an invoice from the seller, so every business in the chain has a reason to document what it collects. A retail sales tax leans more heavily on the final retailer to report accurately, with less built-in verification at earlier stages.
What Rates Look Like Around the World
VAT rates vary widely. Across OECD countries, standard rates run from 5 percent to 27 percent.6OECD. Consumption Tax Trends The European Union, where the system originated, requires member states to keep a standard rate of at least 15 percent, and the EU-wide average is 21.9 percent. Hungary charges the world’s highest standard rate at 27 percent. Luxembourg has the lowest in the EU at 17 percent. Switzerland, outside the EU, charges 8.1 percent.1Tax Foundation. VAT Rates in Europe, 2026
Outside Europe, Australia charges a 10 percent goods and services tax, which is functionally the same mechanism under a different name. Canada charges a 5 percent federal GST, with some provinces adding their own layers on top.
Reduced Rates, Zero Rating, and Exemptions
The headline rate is not what applies to every purchase. Most VAT systems carve out lower rates for goods governments consider socially important: food staples, children’s clothing, books, medical supplies, public transport. Within the EU, countries may apply up to two reduced rates of at least 5 percent and one super-reduced rate below that.1Tax Foundation. VAT Rates in Europe, 2026
Two categories often get confused because they sound alike but produce opposite results for the business. Zero-rated sales carry a 0 percent VAT charge, and the business can still reclaim all the input VAT it paid on related expenses. Exports almost always fall in this category, which is why exporters often receive refunds. Exempt sales also carry no VAT, but the business cannot reclaim input VAT on costs tied to those sales. Financial services, insurance, and residential property rentals are commonly exempt, and the unreclaimable VAT becomes a real cost the business absorbs.
When U.S. Businesses Have to Deal With VAT
An American business without a foreign office can still owe VAT abroad. The most common trigger is selling digital products or services, such as software subscriptions, e-books, streaming media, and online courses, directly to individual buyers in the European Union.
The EU’s One Stop Shop (OSS) system, launched in July 2021, made this manageable. Rather than registering separately in each EU country where a business has customers, a non-EU seller can register in a single member state and file one return that covers all its EU consumer sales. The business charges each customer’s local VAT rate, reports everything through the OSS portal, and makes one payment. For digital services, these returns are filed quarterly.7European Commission.

For physical goods shipped straight to EU consumers, a parallel scheme called the Import One Stop Shop (IOSS) covers consignments valued at €150 or less. Above that value, or if a business opts out of IOSS, the seller may need to register in each country where goods are delivered. The old exemption for small imported parcels under €22 no longer exists, so every item entering the EU now carries some VAT liability regardless of price.7European Commission.

If you sell to individual customers inside the EU, you almost certainly have a VAT obligation there, even with no European staff or premises. The OSS and IOSS systems keep the paperwork centralized, but ignoring the requirement creates genuine legal and financial exposure.
