Value-Added Tax (VAT)

Value-added tax, usually shortened to VAT, is a consumption tax charged on the value added to a good or service at each stage of the supply chain. The European Commission defines it as “a consumption tax on the value added to nearly all goods and services bought and sold in and into the European Union,” an indirect tax that is “borne by the final consumer, not by businesses” and “collected fractionally at every stage of production and distribution.” The Tax Foundation describes a VAT as “a consumption tax assessed on the value added in each production stage of a good or service.” VAT is used across more than 170 jurisdictions, including every OECD member except one. As the Tax Foundation explains, “the US is unique among major countries in that it levies state and local sales taxes instead of a nationwide VAT.”

How VAT Works

VAT is collected in stages rather than once at the end. Each registered business in the chain charges VAT on what it sells (output tax) and reclaims the VAT it paid on what it bought (input tax), remitting only the difference. The cost cascades forward until the final consumer, who cannot reclaim it, carries the full amount. The European Commission notes the tax is “neutral, as the tax borne by the final consumer is the same regardless of the length of the supply chain.” This fractional collection is the core difference from a single-point retail sales tax.

Why a US Company Sees VAT on Foreign Invoices

The United States has no federal VAT. A US company still encounters VAT because contractors and vendors based in VAT countries are required by their own local law to charge it. When a designer in Germany or a developer in the United Kingdom invoices a US client, any VAT line on that invoice is the supplier’s home-country tax. It is not a US tax, it is not paid to the IRS, and it does not flow into any US return. It belongs entirely to the contractor’s jurisdiction.

Whether VAT actually appears depends on the foreign country’s rules for cross-border services. In many business-to-business situations the place-of-supply rules treat the service as supplied where the customer is, and a reverse charge moves the VAT accounting to the buyer, so the supplier issues the invoice without adding VAT. Practice varies by country, so the same kind of engagement can show VAT in one case and not another.

VAT Versus US Sales Tax

Common Points of Confusion

• Treating VAT as a US cost. VAT on a foreign contractor invoice is the contractor’s local tax, not a charge owed to the US government.
• Expecting to reclaim it on a US return. There is no US VAT to credit against. Any recovery runs through the foreign country’s own refund rules, which are often limited for services.
• Assuming VAT always applies. Reverse-charge and place-of-supply rules mean many cross-border business services are invoiced without VAT added.

Related Terms

• Income Tax Treaty: treaties address income tax on cross-border payments. They do not govern VAT, which is a separate consumption tax.
