ITIN for F-1 Visa Holders: Student Tax ID Guide

When F-1 Students Need an ITIN vs SSN

The key difference comes down to work authorization. F-1 students with active employment (on-campus jobs, CPT, or OPT) can and should apply for a Social Security Number through the Social Security Administration. The SSN serves as your tax ID for all filing purposes.

However, many F-1 students find themselves in situations where an SSN is not available. You need an ITIN if you:

• Receive a taxable scholarship or fellowship but do not have work authorization
• Need to file a tax return to claim tax treaty benefits but have no employment
• Earn interest income from a US bank account but are not authorized to work
• Are claimed as a dependent on someone else's tax return and do not have an SSN
• Had your SSN application denied by the Social Security Administration

If you are unsure whether you qualify for an SSN or need an ITIN, check with your university's international student office. They can confirm your work authorization status and advise on the correct path. For general eligibility information, see our who needs an ITIN guide.

OPT and CPT Tax Considerations

F-1 students on Optional Practical Training (OPT) or Curricular Practical Training (CPT) have work authorization and should apply for an SSN rather than an ITIN. Your employer will need your SSN for payroll tax purposes and to issue your W-2 at year end.

Important tax rules for F-1 students on OPT and CPT:

• FICA tax exemption. F-1 students in their first five calendar years in the US are classified as non-resident aliens and are exempt from Social Security and Medicare (FICA) taxes. If your employer withheld FICA taxes in error, you can request a refund.
• Non-resident tax filing. During your first five years on an F-1 visa, you file Form 1040-NR (non-resident return). After five years, you may become a resident alien for tax purposes and file Form 1040 instead.
• State taxes. Most states require F-1 students to file a state income tax return if they earned income in that state. Rules vary by state.

If your OPT or CPT has ended and you no longer have work authorization but still need to file a return, you may need an ITIN for that tax year if your SSN application is no longer valid.

Scholarship and Fellowship Income for F-1 Students

Scholarships and fellowships have specific tax rules that F-1 students must understand. The IRS treats scholarship income differently depending on how the funds are used:

If you receive taxable scholarship income and do not have an SSN, your university may withhold 14% of the taxable portion for federal taxes. An ITIN allows you to file a return, report this income correctly, and potentially claim a refund if too much was withheld.

Tax Treaty Benefits for International Students

The US has income tax treaties with over 65 countries, and many of these treaties include special provisions for students and trainees. These provisions can significantly reduce or eliminate US tax on certain types of income.

Common tax treaty benefits for F-1 students include:

• China (Article 20): Students from China can exclude up to $5,000 per year in wages from US taxation.
• India (Article 21): Indian students can exempt scholarship and fellowship income from US tax.
• South Korea (Article 21): Korean students receiving payments for study, research, or training may be exempt from US tax on those amounts.
• Germany, France, Japan: Various provisions for student and trainee income exemptions, typically for limited periods.

To claim these treaty benefits, you must have either an SSN or ITIN and file Form 1040-NR with Form 8833 (Treaty-Based Return Position Disclosure). Your ITIN application and tax return can be submitted together. For related information, check our guide on ITIN for international students.

How F-1 Students Apply for an ITIN

The ITIN application process for F-1 students follows the standard IRS procedure:

1. Complete Form W-7. Fill out the ITIN application with your legal name, foreign address, date of birth, and visa information. Under “Reason you are submitting Form W-7,” check the appropriate box (usually Box A for filing a tax return or Box H for a dependent).
2. Prepare your identity documents. Your valid passport is the simplest option, satisfying both identity and foreign status requirements. Your F-1 visa, I-20 form, and I-94 record serve as supporting documentation.
3. Complete your tax return. Attach a completed Form 1040-NR to your W-7 application. Include Form 8843 (Statement for Exempt Individuals) and any treaty benefit forms.
4. Submit the application. Mail everything to the IRS ITIN Operation Center, visit an IRS office in person, or use a Certifying Acceptance Agent (CAA) to avoid mailing your original passport.
