US companies do not receive a federal VAT number because the United States does not operate a federal value-added tax system. The US instead uses federal taxes such as income and payroll taxes, along with state and local sales taxes.
That does not mean a US company can ignore VAT. Selling goods or digital services to customers in another country, holding inventory overseas, or using a foreign fulfilment centre can create a requirement to register for VAT or GST in that jurisdiction.
This article is educational information, not tax advice. The correct result depends on the company’s products, customers, sales channels, and operating footprint.
For the broader definition of VAT and GST identifiers, country formats, and validation, see What is a VAT number?. For how the tax itself works, see What is VAT?. This page focuses on the decisions a US company faces when it sells or operates abroad.
If the business has already paid foreign VAT on travel, services, or other expenses, the recovery process is separate; see Can US businesses claim VAT refunds abroad?.
What does a US company use instead?
A US company may have several different tax identifiers, each with a separate purpose:
| Identifier | What it generally identifies |
|---|---|
| EIN | The company for US federal tax and employment purposes |
| State sales-tax permit | Authorisation to collect and remit sales tax in a specific state |
| State business registration | The company’s registration to do business in a state |
| Foreign VAT or GST ID | The company’s registration under another country’s consumption-tax system |
An EIN is not a VAT number. A state sales-tax permit is not a VAT number. Neither one can be entered on a foreign VAT invoice as a substitute for a registration issued by the relevant tax authority.
When might a US company need a foreign VAT number?
There is no single rule for every country, but common triggers include:
Selling goods to foreign customers
A business may need to register when it imports goods, keeps stock in a foreign country, sells through a local warehouse, or makes taxable domestic supplies there. Customs and import obligations can also apply before a VAT registration is issued.
Selling digital services
Digital services, SaaS, subscriptions, and downloads can be subject to special place-of-supply rules. A business-to-consumer sale may be taxed based on the customer’s location, while a business-to-business sale may use a reverse-charge mechanism when the customer has a valid tax number.
The result depends on the country, customer status, evidence of location, and the specific service. “The customer paid from a foreign card” is not always enough to establish the place of supply.
Crossing a registration threshold
Some countries use sales thresholds. Others apply special rules to non-resident sellers, digital services, marketplaces, imports, or low-value goods. The threshold for one country should not be reused for another.
Using a marketplace or fulfilment provider
A marketplace may calculate or collect tax for certain transactions, but that does not automatically remove every obligation from the underlying seller. Inventory, imports, returns, and direct sales can create separate responsibilities.
Businesses with cross-border sales should review international ecommerce tax obligations before assuming that overseas revenue is too small to matter.
Does a US company need a VAT number to sell to Europe?
Not for every sale. A US company can sell to European customers without having a VAT number in every scenario, but European VAT rules may still require registration, collection, reporting, or use of a simplified scheme.
The analysis often depends on:
- Whether the customer is a business or consumer.
- Whether the sale is goods, software, SaaS, or another service.
- Where goods are located when the sale occurs.
- Whether the company imports goods or uses European inventory.
- Whether a marketplace is involved.
- Whether a one-stop or simplified reporting scheme is available.
For B2B transactions, the customer’s VAT number may affect whether VAT is charged on the invoice. It does not automatically prove that the supplier has no registration or reporting obligations.
How does a US company get a VAT number?
The registration process varies by jurisdiction, but the practical sequence is usually:
- Map the business activity. List products, customer types, countries served, sales channels, inventory locations, and fulfilment arrangements.
- Identify the registration basis. Document the sale, import, inventory, digital-service, marketplace, or threshold rule that may apply.
- Choose the correct registration. Some countries offer non-resident, simplified, or one-stop registrations; others require a local tax representative.
- Prepare the application. Common materials include incorporation records, EIN or home-country tax information, bank details, ownership information, invoices, contracts, and a description of the business.
- Submit through the tax authority or authorised representative.
- Confirm the effective date and filing schedule. Approval date, registration date, and the date tax collection should begin may differ.
For example, a US business registering for VAT in Germany should review the process separately from the rules for another EU country. The documentation, tax-office assignment, and local reporting requirements can differ even when the underlying VAT framework is related. See the Germany VAT registration guide for an example of the information a registration review may involve.
How should a US company handle its VAT number?
Once registered, the business needs an operational process—not just a number stored in a tax folder.
Put the number on the right invoices
Use the legal entity and VAT number associated with the transaction. Invoices may need a customer VAT number, a reverse-charge note, a local-language requirement, or a specific tax rate.
Validate customer numbers
For EU VAT numbers, the European Commission’s VIES tool can validate a number issued by an EU Member State or Northern Ireland; Kintsugi's free EU VAT number checker runs the same VIES check. Save the result when it supports a zero-rated or reverse-charge treatment.
Track the registration’s effective date
If a business registered after its obligation began, it may need to address earlier transactions. Do not assume that the approval date erases the period before registration.
Reconcile filings to transaction data
The return should tie back to invoices, credit notes, imports, exemptions, and marketplace reports. A calculation engine is only as reliable as the product, customer-location, and transaction data sent into it.
Common mistakes US companies make
- Calling an EIN a VAT number.
- Assuming US sales-tax registration satisfies foreign registration requirements.
- Treating all overseas customers as consumers or all as businesses.
- Applying a single country’s threshold to every market.
- Assuming a marketplace always handles registration, filing, or liability.
- Missing VAT on inventory, imports, returns, or local fulfilment.
- Using a customer’s tax ID without validating it or preserving evidence.
- Registering in one country but failing to monitor other countries as sales grow.
Kintsugi helps finance and tax teams monitor cross-border exposure, connect transaction sources, and organise tax workflows across sales tax, VAT, and GST. See Kintsugi VAT tax software for a workflow that connects international exposure monitoring to registration and filing. The goal is to make the next registration decision visible before the liability becomes a cleanup project.
Frequently asked questions
Is an EIN the same as a VAT number?
No. An EIN identifies a business for US federal tax purposes. A VAT number identifies a business registered under another jurisdiction’s VAT system.
Can a US company voluntarily register for VAT?
Some jurisdictions allow voluntary registration, while others require a business to meet a specific condition first. Voluntary registration can create filing and recordkeeping obligations, so review the local consequences before applying.
Do US companies charge VAT on every international sale?
No. The correct treatment depends on the jurisdiction, product, customer, place of supply, registration status, and available exemptions or reverse-charge rules.
Can a US company have multiple VAT numbers?
Yes. A company can hold separate VAT registrations in multiple countries or separate registrations within a country where the law requires them.
How do I prove that a customer is VAT-registered?
Use the relevant official validation service and retain the result with the invoice and transaction evidence. For EU numbers, VIES is the standard starting point.
Can a US tax certificate replace a foreign VAT number?
No. The IRS can issue Form 6166 after a business submits Form 8802. A foreign authority may accept that certificate for a specific VAT exemption or refund process, but it does not register the business for VAT and does not replace a foreign VAT number.
