What is the difference between an SSN and ITIN for students?

An SSN is issued by the Social Security Administration to students with US work authorization through on-campus employment, CPT, or OPT. An ITIN is issued by the IRS to students with tax obligations but no work authorization. SSNs prove employment eligibility; ITINs serve federal tax reporting only. You cannot hold both simultaneously.

Do F-1 students need to file US taxes?

Yes. All F-1 students present in the US must file Form 8843 (Statement for Exempt Individuals) annually, even with zero income. If you earned income from employment, taxable scholarships, or fellowships, you must also file Form 1040-NR. You need either an SSN or ITIN to complete the 1040-NR.

Are scholarships taxable for international students?

Scholarships covering tuition and required fees are tax-free under IRC 117. Amounts used for room, board, books, and living expenses are taxable income. Fellowship and grant payments for research or teaching are fully taxable as compensation for services. Report taxable portions on Form 1040-NR using your SSN or ITIN.

Can J-1 visa holders get an ITIN?

Yes. J-1 exchange visitors with tax obligations but no SSN eligibility can apply for an ITIN. This commonly applies to J-1 research scholars, professors, and short-term scholars receiving stipends or fellowship payments. J-1 participants with work authorization should apply for an SSN first through the Social Security Administration.

What tax treaty benefits do international students get?

The US has student-specific treaty provisions with many countries. Chinese students exclude up to $5,000 in wages under Article 20 of the US-China treaty. Indian students exempt scholarship income under Article 21. South Korean students exempt study and research payments. Claim benefits on Form 1040-NR with Form 8833.

What happens when an F-1 student gets OPT?

OPT authorization qualifies you for an SSN. Apply at the Social Security Administration with your I-20 and EAD card. If you previously had an ITIN, contact the IRS to consolidate records under your SSN. Do not use both numbers. FICA exemption continues during OPT while you remain a non-resident alien.

How long does it take for a student to get an ITIN?

The IRS processes ITIN applications in 6 to 11 weeks by mail. Apply early in the tax year to receive your ITIN before the April 15 filing deadline. itin.so offers standard ($297, 7-10 business day preparation) and express ($297, 2-3 business day preparation) service with CAA document verification.

ITIN for International Students 2026: F-1 and J-1 Visa Tax Filing Guide

Q: How do international students apply for an ITIN?

Complete Form W-7 and attach Form 1040-NR. You need a valid passport and a letter from your Designated School Official (DSO) for F-1 or Responsible Officer (RO) for J-1 confirming your student status. Submit by mail, at an IRS office, or through a CAA like itin.so for $297.

Q: Are F-1 students exempt from FICA taxes?

Yes, for the first 5 calendar years in the US. F-1 students classified as non-resident aliens under IRC 3121(b)(19) are exempt from Social Security tax (6.2%) and Medicare tax (1.45%). If your employer withholds FICA in error, file Form 843 and Form 8316 to request a refund from the IRS.

Over 1.1 million international students study in the US, and every one of them must file at least Form 8843 annually. An ITIN for international students is required when you have taxable scholarship or fellowship income but lack work authorization for an SSN. The US has student-specific tax treaty provisions with 67+ countries, including a $5,000 wage exemption for Chinese students under Article 20. itin.so processes student applications for $297.

When Do International Students Need an ITIN vs SSN?

The deciding factor is work authorization. Students with employment authorization (on-campus, CPT, OPT) qualify for an SSN and must apply for one first. The IRS rejects ITIN applications from SSN-eligible individuals. You need an ITIN if:

You receive taxable scholarship or fellowship income beyond tuition and required fees but have no work authorization
You need to file Form 1040-NR to claim a tax treaty exemption on scholarship or fellowship income
Your spouse or dependent needs a US tax ID for inclusion on your return
You earn investment income, prizes, or awards requiring US tax reporting but have no work authorization

SSN vs ITIN Comparison for Students

How Is Scholarship and Fellowship Income Taxed for International Students?

IRC 117 defines the tax treatment. 2 categories:

Tax-Free (IRC 117(a)): Tuition + Required Fees

Scholarship amounts used for tuition, mandatory university fees, and required course materials listed on the syllabus are not taxable. These amounts do not appear on Form 1040-NR.

Taxable (IRC 117(c)): Room, Board, Living Expenses

Amounts covering room, board, travel, optional equipment, or living expenses are taxable income. Teaching and research assistantship stipends are fully taxable as compensation. Report on Form 1040-NR using your SSN or ITIN.

Withholding on Taxable Scholarships

Universities withhold 14% of taxable scholarship amounts for students without an SSN under IRC 1441(c)(7). An ITIN allows you to file Form 1040-NR, report income correctly, and claim a refund if too much was withheld. Many countries have treaties that fully exempt scholarship income from US tax.

Which Tax Treaty Benefits Apply to International Students?

The US has income tax treaties with 67+ countries, and many include student-specific provisions. Claim benefits on Form 1040-NR with Form 8833 (Treaty-Based Return Position Disclosure).

Country	Treaty Article	Benefit
China	Article 20	$5,000 annual wage exemption
India	Article 21	Scholarship and fellowship exemption
South Korea	Article 21	Study and research payment exemption
Germany	Article 20	Student maintenance payments exemption
Japan	Article 20	Education and training exemption

Are International Students Exempt from FICA Taxes?

Yes, for the first 5 calendar years. F-1 and J-1 students classified as non-resident aliens are exempt from Social Security tax (6.2%) and Medicare tax (1.45%) under IRC 3121(b)(19). This applies to on-campus employment, CPT, and OPT positions.

Employer Withheld FICA in Error

If your employer incorrectly withheld FICA taxes, first request a refund from your employer. If the employer refuses, file Form 843 (Claim for Refund) and Form 8316 with the IRS to recover the overpayment. Attach copies of your W-2 showing the erroneous withholding.

After 5 Years: Resident Alien Status

After 5 calendar years, you may become a resident alien for tax purposes under the substantial presence test. This means you file Form 1040 (not 1040-NR), lose NRA-specific treaty benefits, and must pay FICA taxes. Your ITIN may need to be renewed or replaced with an SSN if you gain work authorization.

What Happens to Your ITIN When You Get OPT?

OPT (Optional Practical Training) provides 12 months of work authorization (24 months for STEM fields). OPT qualifies you for an SSN. Apply at the Social Security Administration with your I-20, EAD card, and passport.

Once you receive your SSN, contact the IRS to consolidate your ITIN and SSN records. Do not use both numbers simultaneously. Your FICA exemption continues during OPT while you remain within your first 5 calendar years and maintain non-resident alien status.

STEM OPT participants on 24-month extensions continue the FICA exemption for up to 5 total calendar years. After that, FICA applies to all employment income. Learn more about F-1 visa holder tax obligations.
