Quick answer: Nonresident alien F-1 students are generally exempt from FICA taxes (Social Security 6.2% and Medicare 1.45%) on wages from on-campus jobs, CPT and OPT during their first five calendar years in the USA. If your employer deducted FICA, first ask the employer to refund it; if they refuse, file IRS Form 843 with Form 8316 and supporting documents.
Imagine you finally start your OPT job with a $90,000 salary. When the first paystub arrives, you see two deductions labelled Social Security and Medicare. Together they take 7.65% of your pay. On $90,000, that is close to $6,900 a year. For most Indian students on OPT, these taxes should not have been deducted at all. This guide explains the FICA exemption and how to get your money back.
What is FICA?
FICA stands for the Federal Insurance Contributions Act. It funds Social Security and Medicare. Normally, employees pay:
- 6.2% Social Security tax, up to an annual wage limit
- 1.45% Medicare tax on all wages
The employer pays a matching amount. FICA is separate from federal and state income tax.
Who is exempt?
US tax law exempts wages paid to nonresident alien students in F-1, J-1, M-1 or Q status for services that are allowed by their immigration status. In practice, for Indian F-1 students, this covers:
- On-campus jobs during studies
- CPT internships
- Post-completion OPT and STEM OPT
The exemption applies only while you are a nonresident alien for tax purposes. F-1 students are usually nonresidents for their first five calendar years in the USA. Read our F-1 tax filing guide to understand the five-year count.
Who is NOT exempt?
- F-1 students who have become resident aliens after five calendar years.
- F-2 dependents, who cannot work anyway.
- H-1B workers. Once you change status to H-1B, FICA applies from that date.
- Green Card holders.
Example: the five-year count
| Calendar year | Status | Year count | FICA |
|---|---|---|---|
| 2022 (arrived August) | F-1 student | 1 | Exempt |
| 2023 | F-1 student | 2 | Exempt |
| 2024 (graduated, OPT) | F-1 OPT | 3 | Exempt |
| 2025 | F-1 STEM OPT | 4 | Exempt |
| 2026 | F-1 STEM OPT | 5 | Exempt |
| 2027 | F-1 STEM OPT | Resident alien | Not exempt |
If you previously spent time in the USA on F or J status, those years count too, which may shorten your exempt period.
Why employers make mistakes
Payroll systems often treat everyone with an SSN as a regular employee. HR teams may not know the student rule, or your onboarding form may not have captured your visa status correctly. Large tech employers usually handle it well, but small and mid-sized companies and staffing firms frequently get it wrong.
How to check if FICA is being deducted
- Look at your paystub for lines like “Social Security”, “OASDI”, “Medicare” or “FICA”.
- Check your W-2: Box 4 shows Social Security tax withheld and Box 6 shows Medicare tax withheld.
- If these are not zero and you are still a nonresident F-1, you are likely owed a refund.
How to get a FICA refund
Step 1: Ask your employer first
Email HR or payroll with a short note explaining you are an F-1 nonresident alien and exempt under Internal Revenue Code section 3121(b)(19). Attach your I-20, EAD card and proof of nonresident status. Employers can usually correct the current year directly and refund you through payroll. Ask them to update your status so future paychecks are correct.
Step 2: If the employer refuses or cannot refund
File with the IRS directly:
- Form 843 – Claim for Refund and Request for Abatement
- Form 8316 – Information regarding request for refund of Social Security tax erroneously withheld
- Copy of your W-2
- Copy of your passport, visa, I-94, I-20 and EAD card
- Copy of your Form 1040-NR for that year
- A letter from the employer stating they will not refund, or a statement explaining you tried
Mail the package to the IRS address listed in the Form 843 instructions. Processing often takes several months.
Step 3: Time limit
You generally have up to three years from the filing deadline of the year in question to claim a refund. Don’t wait too long.
How much money is at stake?
A student earning $15,000 a year on campus could lose about $1,150 in wrongly deducted FICA. An OPT employee earning $100,000 could lose about $7,650 in one year. That money could clear part of an education loan. See our education loan repayment strategy.
Won’t I lose Social Security benefits?
Social Security benefits generally require 40 work credits, roughly 10 years of work. If you return to India, FICA paid during student years would rarely help you. Note that India and the USA do not currently have a Social Security totalization agreement, so contributions are not transferable to India.
Tips for OPT job seekers
- Mention your FICA-exempt status during onboarding.
- Check your first paystub carefully.
- Some employers see your exemption as a small cost saving because they also skip the employer match.
Sample email to your payroll team
Many students hesitate to raise this with HR. A short, polite email works well. You can say that you are an F-1 student on OPT, that you are a nonresident alien for tax purposes because you are within your first five calendar years in the USA, and that your wages are exempt from Social Security and Medicare taxes under section 3121(b)(19) of the Internal Revenue Code. Ask them to stop withholding FICA from future paychecks and to refund the amounts already withheld this year. Attach your I-20, EAD card and a statement of your arrival dates.
Keep a copy of every email. If the employer does not respond within a reasonable time, the written record helps your Form 843 claim with the IRS, because the IRS expects you to try the employer first.
Frequently asked questions
Is my income tax also exempt?
No. Federal and state income taxes still apply, although Indian students can claim the treaty standard deduction.
Does FICA apply after I switch to H-1B?
Yes, from the date your status changes to H-1B.
I am on STEM OPT in my sixth year. Am I exempt?
Likely not, because you probably became a resident alien for tax purposes.
Bottom line
If you are an Indian F-1 student in your first five years, check boxes 4 and 6 on your W-2. If you see money there, claim it back. It is your money, and the process is well established.
