Do F-1 Students Pay FICA Taxes?
Quick Answer
No, F-1 students are exempt from FICA taxes (Social Security and Medicare) during their first five calendar years in the US, as long as they are classified as nonresident aliens. After the five-year exemption period, or upon becoming a resident alien, FICA taxes apply.
Key Takeaway
If your employer is deducting Social Security or Medicare taxes from your paycheck during your first five years on F-1 status, request a correction immediately and file for a refund using Form 843.
The FICA Exemption for F-1 Students
FICA stands for the Federal Insurance Contributions Act and covers Social Security tax (6.2%) and Medicare tax (1.45%). Together, these amount to 7.65% of your gross wages. Under Internal Revenue Code Section 3121(b)(19), F-1 students who are nonresident aliens are exempt from FICA taxes on wages earned in connection with their student status.
This exemption applies during the first five calendar years you are present in the US in F-1 status. The five-year count is based on calendar years, not full 365-day periods. For example, if you arrived in August 2022, the year 2022 counts as your first calendar year, even though you were only present for five months. Your exemption would generally run through December 31, 2026.
The exemption covers all employment authorized under your F-1 visa, including on-campus employment, CPT, OPT, and STEM OPT. Your employer is responsible for not withholding FICA taxes from your paycheck, but many payroll departments are unfamiliar with this rule and may withhold them incorrectly.
What to Do If FICA Was Incorrectly Withheld
If your employer has been deducting Social Security and Medicare taxes from your paychecks, you should first contact your payroll or HR department and request a correction. Provide them with a copy of your I-20 and explain the FICA exemption under IRC Section 3121(b)(19). In most cases, the employer can issue a corrected W-2 and refund the withheld amounts.
If your employer refuses to correct the withholding or is unable to issue a refund, you can file for a refund directly with the IRS using Form 843 (Claim for Refund and Request for Abatement) along with Form 8316. You will need to include your W-2, a copy of your I-20, your I-94 record, passport, visa, and a statement explaining your nonresident alien status.
- Contact payroll/HR and request a FICA withholding correction
- Provide your I-20, I-94, and passport as documentation
- If employer cannot refund, file Form 843 with the IRS
- Include Form 8316 and all supporting immigration documents
- The IRS refund process can take 6 to 12 months
You generally have three years from the date of the tax return to claim a FICA refund. Do not wait too long to file Form 843.
When the FICA Exemption Ends
After spending more than five calendar years in the US in F-1 status, you may become a resident alien for tax purposes under the Substantial Presence Test. Once you are classified as a resident alien, the FICA exemption no longer applies and your employer must begin withholding Social Security and Medicare taxes from your wages.
There are some exceptions. If you change to a different visa status (such as H-1B) before the five-year period ends, your FICA exemption may end at that point. Conversely, if you left the US for a substantial period and re-entered on a new F-1 visa, the five-year clock may reset in certain circumstances. Consult a tax professional if your situation involves multiple entries or status changes.
FICA and OPT/STEM OPT Employment
Students working on OPT or STEM OPT remain eligible for the FICA exemption as long as they are within the five-year nonresident alien period. This is a significant financial benefit, saving you 7.65% on every dollar earned. For a student earning $70,000 annually on STEM OPT, that amounts to over $5,300 per year in savings.
Some employers, especially large corporations with automated payroll systems, may default to withholding FICA from all employees. Be proactive during onboarding by informing your HR department about your FICA-exempt status and providing documentation upfront. Many universities also provide template letters you can share with your employer.
