What is a TIN number?

The TIN, or Tax Identification Number, is a tax identification number assigned by the US tax authorities. It is a unique number that identifies the taxpayer, whether an individual, a company or any other legal entity with U.S. tax obligations.

This U.S. tax identification number is essential for filing a U.S. tax return, opening an account with the IRS, opening a U.S. bank account, making a payment, receiving U.S.-source income or accessing certain banking or administrative services. There are several types of TIN, depending on the taxpayer’s profile:

SSN (Social Security Number) for individuals
EIN (Employer Identification Number) for companies and employers
ITIN (Individual Taxpayer Identification Number) for those not eligible for SSN

Assigned by the IRS (Internal Revenue Service), the TIN number is therefore a central element of all tax identification in the United States, guaranteeing the traceability, compliance and integration of the taxpayer into the American tax system.

Frequently asked questions

What types of TIN numbers are available in the United States?

The Internal Revenue Service (IRS) offers several types of Tax Identification Numbers (TINs) for U.S. tax returns and liability management. Here are the main ones:

Social Security Number (SSN): Assigned to US citizens as well as certain eligible residents. This number is used primarily for personal tax returns and social security benefits
Employer Identification Number (EIN): Designed for business entities such as corporations, limited liability companies (LLCs), partnerships, as well as non-profit organizations. This number is used to identify employers and manage their tax obligations
Individual Taxpayer Number (ITIN) : Intended for people who cannot obtain an SSN, such as non-residents or certain foreign residents with U.S. tax obligations
Other TINs: Among them, the Adoption Specialist Number (ATIN) and the Tax Return Preparer Number (PTIN), used in specific cases

What's the difference between TIN and NIF?

TIN (Tax Identification Number) is the term used in the USA to designate the tax identification number assigned to a taxpayer by the IRS. In Europe, the equivalent is generally called NIF (Numéro d'Identification Fiscale). So, depending on the country concerned, it may be referred to as a NIF or TIN, but the purpose remains the same: to enable an individual or legal entity to be identified for tax purposes by the competent authorities. In an American context, only the TIN is recognized, whereas for European tax identification, the NIF applies.

What documents contain the TIN number?

The TIN number appears on several types of official documents, depending on the nature of the TIN assigned. For an SSN, it appears on the social security card. For an ITIN or EIN, the TIN is mentioned on the letter issued by the IRS. It can also be found on the first page of a U.S. tax return, or in correspondence relating to the tax and compliance obligations of a company or individual.

What are the requirements for obtaining a TIN number?

To obtain a TIN number, several pieces of information must be provided to the IRS. The main requirements include:

The applicant's country of residence
His date of birth (in the case of an individual)
Valid proof of identity
The type of intended tax use (income tax return, withholding tax, setting up a business in the USA, etc.)

These elements are essential to ensure the correct tax identification of the taxpayer and to enable registration in the American tax system.
