In case you have to file taxes in the USA, the presence of the proper tax identification number is imperative. Quite a few people and business proprietors, particularly non-residents and foreigners, are not sure which number they require. By knowing the differences between the U. S. individual tax identification number, Social Security Number (SSN), and EIN tax identification number, one can guarantee accurate tax filing and prevent delays and penalties from the IRS.
This guide explains how each tax identification number works, who needs it, and when it applies.
What Is a U.S. Individual Tax Identification Number (ITIN)?
An ITIN is what the IRS refers to as a U. S. individual tax identification number, and it is issued to people who are obliged to submit U. S. tax returns, although they are not entitled to a Social Security Number.
The ITIN is used strictly for tax reporting purposes. It does not authorize work in the U.S. or provide immigration benefits.
Individuals who typically need individual taxpayer identification numbers include:
- Non-resident aliens who need to submit U. S. tax returns
- Foreign nationals having income from the U. S.
- Children or partners of U. S. taxpayers who are not eligible for SSNs
- Foreign investors getting income sourced from the U. S.
Without a valid ITIN, tax returns cannot be processed by the IRS.
Understanding the Social Security Number (SSN)
An SSN is issued by the Social Security Administration and is primarily used for employment and benefit purposes. U.S. citizens and certain authorized non-citizens receive SSNs.
Key characteristics of an SSN include:
- Used for employment eligibility
- Required for payroll and wage reporting
- Used for personal income tax filing
- Linked to Social Security benefits
An individual who is given a Social Security Number (SSN) is barred from obtaining a U. S. Individual Taxpayer Identification Number (ITIN). Moreover, the Internal Revenue Service (IRS) permits only one main tax ID number per person.
What Is An Employer Identification Number?
An Employer Identification Number (EIN) is an identification number issued by the IRS for the purpose of tax administration. An EIN is intended for use by employers, corporations, partnerships, and any other entity that needs to be identified in relation to tax liabilities, sales tax, and employment tax.
An EIN is required for:
- An LLC, corporation, or partnership
- A business with employees
- Filing business tax returns
- Opening a U. S. business bank account
- The employer for payroll and withholding taxes
Many foreign-owned U. S. companies, even if their owners do not reside in the United States, may need to obtain an EIN.
ITIN vs SSN vs EIN – Key Differences Explained
Knowing the distinction between these tax IDs assists in avoiding mistakes during tax filing and consequently delays in processing.
- ITIN is for those individuals who are required to file taxes but cannot get an SSN.
- SSN is assigned to persons who are authorized to work in the U. S.
- EIN is for companies and legal entities, not for individual tax returns.
- ITIN and SSN are reported on individual tax returns.
- EIN is reported on business and payroll tax returns.
Each serves a specific purpose under U.S. tax law.
When Do You Need an Individual Taxpayer Identification Number?
In case you receive U. S. income but are not entitled to an SSN, you will probably require an individual taxpayer identification number. Income from real estate rental, investments, partnership, or owning a U. S. business can be included in this category.
Common scenarios include:
- Filing a U.S. tax return as a non-resident
- Reporting U.S. income as a foreign investor
- Claiming dependents on a U.S. tax return
- Filing jointly with a spouse who does not qualify for an SSN
The IRS requires proper documentation to issue or renew a U.S. individual tax identification number.
ITIN Application and Renewal Considerations
ITINs must be renewed periodically. If an ITIN expires, the IRS may reject tax returns or delay refunds.
Important points to remember:
- ITINs are no longer valid if they are not listed on a tax return for three successive years
- Tax returns cannot be filed with an expired ITIN
- Documentation has to comply with IRS requirements
- Mistakes may lead to significant processing delays
Professional assistance helps ensure applications and renewals are completed the first time correctly.
Choosing the Right Tax Identification Number Matters
The submission of an incorrect tax identification number can lead to the aforementioned filings being rejected, together with the imposition of penalties and the postponement of refunds. In case you require a tax identification number in the form of ITIN, SSN, or EIN, the correct categorization is a must for compliance with the IRS.
International taxpayers and foreign-owned enterprises trying to comply with U. S. tax regulations for the very first time will find that having clear instructions is of utmost importance.

Understanding the differences among a U. S. individual tax identification number, a social security number, and an employer identification number is necessary for proper tax declaration and compliance.
