What is an ITIN Number? How to Apply for an ITIN?

To comply with U.S. tax regulations, you may need an ITIN, or Individual Taxpayer Identification Number, if you are earning money in the United States but not eligible for a Social Security Number (SSN).

Complying legally and financially with United States laws starts with understanding the ITIN, regardless of whether you are a foreign entrepreneur, an investor, a student, or a dependent.

This comprehensive guide explains everything from what an ITIN Number is and who needs one to how to apply and avoid common pitfalls, as well as how Bizstartz can assist you with reputable professional guidance throughout the process.

What is an ITIN?

An Individual Taxpayer Identification Number, or ITIN, is a distinct nine-digit tax processing number allocated by the IRS (Internal Revenue Service).

It caters to individuals who lack a Social Security Number from the Social Security Administration, yet need to fulfill U.S. tax requirements.

The format of the number is like that of an SSN:

🔢 9XX-XX-XXXX

To provide unattached foreigners and individuals,who do not qualify under a certain criteria, to meet US tax filing requirements, the ITIN has been designated. Aside from the important role that it plays in the federal tax system, the ITIN is bound within these limits:

  • It cannot function as a work permit.
  • It does not guarantee immigration status.
  • Civil rights as citizens of the government are not available to holders.

🔎 The IRS has clearly stated that the only function of the ITIN is as a federal form of tax reporting. Allowing income to be reported, taxes to be paid, and certain tax rebates to be claimed no matter what one’s condition is, is the work of ITIN.

👤 Who Needs an ITIN?

United States citizens, foreign nationals, or individuals conducting business outside the US are eligible for an ITIN if they have relations, legal or financial with the US. The following explanation may help you assess whether you need an ITIN.

📌 Common Scenarios Requiring an ITIN:

  • Non-resident aliens who are obligated to pay taxes in the US as mandated within the tax-eligible boundaries of the IRS.
  • US resident aliens (determined by physically present in USA for certain number of days) who are also tax filers.
  • Spouses or dependents of U.S. citizens or resident aliens who are not eligible for SSNs.
  • Spouses or dependents of non-resident visa holders (H-1B, F-1, L-1).
  • Foreign investors, partners, or LLC members who derive income from the U.S or have a business entity like an LLC or LLP.
  • Non-resident individuals deriving rental income, dividends, royalties, or interest from U.S. assets.
  • Foreign students, scholars, or faculty members undertaking tax returns or tax treaty claims.
  • Claiming tax treaty benefits for reducing tax liability resulting from simultaneous taxation.

🧾 Note: Without requiring physically visiting or living in the US, having certain connections such as an income classified under the US system may activate certain obligations including filing for taxes, which require an ITIN number.

🚫 Restrictions on the ITIN

⚠️ Key Limitations:

Limitation Explanation

❌ No eligibility for benefits ITIN holders cannot receive Social Security, Medicare, unemployment, or retirement benefits.

❌ Limited identification use It’s not considered an official ID by most federal and state agencies.
⏳ Subject to expiration ITINs must be used at least once every three years or they will expire. Older ITINs issued prior to 2013 are subject to automatic renewal cycles.

🛑 Many people incorrectly assume that the ITIN allows people to legally reside or work in the United states, but this is not true. The ITIN was created only for the purpose of identifying taxpayers.

  • Acquiring a state issued driver’s license (from most states)
