When it comes to filing taxes in the United States, understanding the difference between an ITIN (Individual Taxpayer Identification Number) and an SSN (Social Security Number) is crucial. Both are used to identify individuals for tax purposes, but they serve different purposes and are issued to different groups of people. This article explains the differences between an ITIN and an SSN, and when to use each one when filing your taxes.
What is an SSN (Social Security Number)?
An SSN is a nine-digit number issued by the Social Security Administration (SSA) to U.S. citizens, permanent residents (green card holders), and certain non-resident aliens who are authorized to work in the U.S. It serves multiple purposes, including:
- Tracking an individual’s earnings for Social Security benefits.
- Determining eligibility for government services and benefits.
- Filing taxes and reporting income to the IRS.
The SSN is used primarily for U.S. citizens and lawful residents, and it’s a key number for anyone who works in the U.S. or wishes to claim Social Security benefits in the future.
What is an ITIN (Individual Taxpayer Identification Number)?
An ITIN is a tax processing number issued by the IRS to individuals who are required to file a U.S. tax return but are not eligible for an SSN. ITINs are generally issued to:
- Non-resident aliens who are required to file taxes.
- U.S. resident aliens who are not eligible for an SSN.
- Dependents or spouses of U.S. citizens or resident aliens.
Unlike the SSN, an ITIN cannot be used to authorize work in the U.S. or to qualify for Social Security benefits. It is strictly used for tax purposes. The ITIN is also nine digits long and formatted like an SSN, but it begins with a “9.”
When to Use an SSN
An SSN is used when an individual is authorized to work in the U.S. or is a U.S. citizen or permanent resident. If you are a U.S. citizen or hold a green card, you should use your SSN to file taxes. It is required when:
- You are employed in the U.S. and your employer is required to report your income to the IRS.
- You are claiming Social Security benefits or making contributions to Social Security.
- You are filing tax returns and claiming deductions, exemptions, or credits as a U.S. citizen or permanent resident.
When to Use an ITIN
If you do not qualify for an SSN but still need to file a tax return in the U.S., you will need to use an ITIN. Common scenarios include:
- If you are a non-resident alien who earns income in the U.S. but is not eligible for an SSN.
- If you are a dependent or spouse of a U.S. citizen or permanent resident and need to file taxes.
- If you are a resident alien for tax purposes but not eligible for an SSN (such as some non-working immigrants).
ITINs are issued only for tax reporting purposes and do not grant the right to work in the U.S. or receive Social Security benefits.
Key Differences Between ITIN and SSN
| Feature | SSN (Social Security Number) | ITIN (Individual Taxpayer Identification Number) |
| Purpose | Used for work authorization, Social Security benefits, and tax reporting | Used for tax reporting purposes only |
| Eligibility | U.S. citizens, permanent residents, and eligible non-resident aliens | Non-residents, residents, and dependents who are not eligible for an SSN |
| Social Security Benefits | Eligible for Social Security benefits | Not eligible for Social Security benefits |
| Work Authorization | Required for employment in the U.S. | Does not grant work authorization |
How to Apply for an ITIN or SSN
To apply for an SSN, you must fill out Form SS-5 and submit it to the Social Security Administration (SSA) along with required documents, such as proof of your citizenship, permanent residency, or work authorization.
To apply for an ITIN, you need to fill out IRS Form W-7, along with supporting documents such as a valid passport or other identification. ITIN applications are processed by the IRS, and you can apply for one when filing your first tax return.
Whether you are an immigrant, a non-resident, or a U.S. citizen, understanding the difference between an ITIN and SSN is key to filing taxes in the U.S. An SSN is required for those who are eligible to work and claim Social Security benefits, while an ITIN is a substitute for those who cannot obtain an SSN but still need to file taxes. By using the correct identification number, you can ensure your taxes are filed accurately and in compliance with IRS regulations.
