The United States Does Not Have a Federal VAT, and Therefore Has No VAT Number or Corresponding Registration Process

The United States does not have a federal-level Value-Added Tax (VAT), a fact that frequently leads to misunderstandings among professionals new to cross-border taxation. Many Chinese sellers, when registering a U.S. company and applying for a tax identification number, instinctively draw parallels with the VAT systems in the European Union or Southeast Asia-repeatedly searching the IRS (Internal Revenue Service) system for a “VAT number,” only to discover that such a concept simply does not exist. In reality, the U.S. operates a hybrid tax system centered on state-level Sales Tax, supplemented by federal income taxes. Each state independently determines whether to impose sales tax, sets its own rates, and administers collection-while the federal government is responsible only for direct taxes such as corporate income tax, individual income tax, and employment taxes. In April 2026, the U.S. Supreme Court once again rejected litigation seeking nationwide standardization of online sales tax rules, thereby reaffirming-more deeply than ever-the states’ retained authority over sales tax legislation. This means the notion of a “U.S. VAT number” lacks legal foundation from its very origin.

I. The U.S. Does Not Have a Federal VAT Number

1. The U.S. federal government has never established a VAT system, nor has it authorized any agency to issue a “VAT Number” or any similar identifier.

2. The only universal federal tax identification number issued by the IRS is the Employer Identification Number (EIN), which is used exclusively for federal tax-related purposes-including filing tax returns, opening bank accounts, and hiring employees.

3. Sales tax is administered at the state level; businesses must apply separately to each state’s tax authority for a Sales Tax Permit. This permit number bears no relationship to the EIN and is not transferable across states.

4. On platforms such as Amazon and Walmart, the “Tax ID” field displayed in seller backends accepts an EIN solely for verifying the seller’s legal entity status-not as a basis for sales tax reporting or compliance.

II. Core Process and Practical Key Points for EIN Registration

The EIN serves as the foundational credential for conducting tax-related activities in the United States. It can currently be obtained free of charge only through the official IRS website

1. Applicants who are non-resident aliens or foreign entities must designate a “Responsible Party” residing in the U.S., who must possess either a Social Security Number (SSN) or an Individual Taxpayer Identification Number (ITIN).

2. Complete Form SS-4 via the IRS website, selecting the “International Applicants” pathway, and submit the application entirely online.

3. Upon successful submission, the EIN is generated instantly; a PDF confirmation letter (CP 575) will be mailed to the address provided in the application within 4-6 weeks.

4. Important note An EIN cannot substitute for a state-level sales tax registration number. If you plan to ship goods into high-compliance jurisdictions such as California or New York, you must complete separate state-level registration.

III. Critical Variations in Obtaining a Sales Tax Number

Sales tax is levied and administered by individual states, and operational procedures differ significantly across jurisdictions

1. Florida allows one-click application for a Sales Tax Permit via the Florida Department of Revenue’s official website, with processing typically completed within approximately three business days.

2. Texas requires applicants to provide proof of a commercial physical address and a recent bank statement; moreover, the first sales tax return must be filed within 30 days of permit approval.

3. Pennsylvania will mandate remote sellers to register online using Form PA-100 starting October 2026-and simultaneously integrate with certified tax software providers such as Avalara.

4. Washington State introduced, effective 2026, a dynamic “economic nexus threshold” mechanism sellers exceeding $100,000 in annual gross sales into the state become obligated to register for sales tax-regardless of physical presence.

IV. Common Misconceptions and Risk Warnings

Numerous companies encounter operational disruptions due to conceptual confusion

1. Mistakenly uploading an EIN as a sales tax number to e-commerce platforms results in system-flagged “incomplete qualification,” leading to suspended order settlements.

2. Shipping goods to consumers in New York State without first obtaining a NY sales tax registration triggers retroactive liability for up to three years of unpaid tax plus interest and penalties. According to the New York State Department of Taxation and Finance (NYSDTF), the average assessed deficiency amount in 2026 was $8,200.

3. Using third-party agents to apply for an EIN-but failing to retain actual control over the associated IRS online account-prevents subsequent updates to tax information or downloading of official reports.

4. Assuming that “sales tax registration is unnecessary in ‘tax-free’ states (e.g., Delaware or Montana)” overlooks critical nexus triggers-such as inventory stored in an FBA warehouse located in Tennessee, which may still create a sales tax obligation.

The above outlines the logic and registration pathways for U.S. tax identification numbers against the backdrop of the absence of a federal VAT system. We hope this provides valuable guidance. Before launching your business, we recommend first identifying your target sales states, then reviewing-individually and thoroughly-each state’s sales tax registration thresholds and required documentation, to avoid cash-flow delays and platform compliance issues arising from misaligned tax identifiers.
