If you’re on an F-1 visa and your pay stub shows Social Security and Medicare, look twice. Most F-1 students who are still nonresident aliens for tax purposes don’t owe either tax on wages from a campus job, CPT, OPT, or STEM OPT.
Those two lines are FICA, and together they take 7.65% of gross pay. On a $75,000 OPT salary paid every two weeks, that’s $220.67 per check that may not belong there.
The exemption isn’t automatic, and the visa stamp alone doesn’t decide it. You qualify when three things line up: you’re a nonresident alien for tax purposes, you’re in F-1 (or J-1, M-1, or Q-1) status, and the work is authorized and tied to that status. It removes FICA only. Federal and state income tax still apply.
What the F-1 FICA exemption saves on each paycheck
FICA is two taxes. Social Security takes 6.2% of wages up to the 2026 wage base of $184,500, and Medicare takes 1.45% of every dollar. FICA taxes explained covers how both work for a regular employee.
The F-1 exemption comes from one sentence in the tax code. IRC §3121(b)(19) says work by a nonresident alien temporarily in the U.S. under F, J, M, or Q status, done to carry out the purpose of that status, isn’t “employment” for FICA. No employment means no Social Security or Medicare tax on those wages.
Every salary in the table below sits well under the wage base, so the full 7.65% applies to each dollar.
| Annual wages | Social Security (6.2%) | Medicare (1.45%) | Annual FICA | Per biweekly check | Per semimonthly check | Per monthly check |
|---|---|---|---|---|---|---|
| $16,640 (campus job) | $1,031.68 | $241.28 | $1,272.96 | $48.96 | $53.04 | $106.08 |
| $50,000 | $3,100.00 | $725.00 | $3,825.00 | $147.12 | $159.38 | $318.75 |
| $75,000 | $4,650.00 | $1,087.50 | $5,737.50 | $220.67 | $239.06 | $478.13 |
| $100,000 | $6,200.00 | $1,450.00 | $7,650.00 | $294.23 | $318.75 | $637.50 |
The campus-job row assumes 20 hours a week at $16 an hour for all 52 weeks. Per-check figures are annual FICA divided by the number of pay periods, so your stub may differ by a cent because payroll rounds each line separately.
Your employer skips its own matching 7.65% on exempt wages too, a point the Department of Homeland Security (DHS) makes in its STEM OPT guidance. Fixing a withholding mistake usually saves the company money as well, which helps when you bring it up with HR.
Who qualifies: three conditions, not just the visa
Plenty of students (and payroll departments) treat “F-1” as the whole test. It isn’t. The IRS says students must keep nonresident alien status, and the work has to be something immigration rules allow. You need all three conditions below.
1. You’re a nonresident alien for tax purposes
Tax residency is separate from immigration status. It’s decided by the substantial presence test in IRC §7701(b), covered below. IRS Publication 519 says Social Security and Medicare are withheld once you’re a resident alien, even if your F, J, M, or Q classification hasn’t changed.
2. You’re in F-1, J-1, M-1, or Q-1 status
These are the primary student and exchange classifications. Q-1 cultural exchange visitors qualify only when the employer is the one that petitioned for their Q visa.
3. The work is authorized and tied to your status
The IRS lists the kinds of work that count:
- On-campus jobs, up to 20 hours a week while school is in session and 40 hours a week during summer vacation
- Off-campus work that USCIS allows, including economic-hardship employment
- Practical training, on or off campus
Practical training covers both CPT (curricular practical training) and OPT (optional practical training). The 24-month STEM OPT extension is an extension of OPT, so it qualifies too. DHS says STEM OPT workers generally aren’t subject to FICA until after their first five calendar years in F-1 status.
Unauthorized work never qualifies. Neither does work that isn’t for the purpose of your status.
Who doesn’t qualify
- F-2, J-2, M-2, and Q-3 spouses and children. Pub 519 says their work is covered by Social Security, so FICA applies even while the F-1 or J-1 holder is exempt.
- Anyone who changes status. A switch to H-1B ends the exemption from the H-1B start date, even if you’re still a nonresident for income tax that year. During the cap-gap period, DHS says your F-1 status and OPT work authorization are extended until the change of status takes effect, so the exemption generally holds until then.
- Students who’ve become resident aliens, usually in their sixth calendar year.
J-1 and M-1 notes
J-1 and M-1 students follow the same five-year clock as F-1 students. J-1 researchers, professors, teachers, and trainees who aren’t students run on a shorter one: they generally can’t exclude their days if they were exempt as a teacher, trainee, or student for any part of 2 of the previous 6 calendar years. J-1 work also needs authorization from your program sponsor.
The five-calendar-year clock and the substantial presence test
The year FICA starts depends on the substantial presence test and its carve-out for students.
The substantial presence test
You’re a U.S. resident for tax purposes if you’re here at least 31 days this year and 183 days over three years, counted this way:
- every day this year
- one-third of the days last year
- one-sixth of the days the year before that
Days as an “exempt individual” don’t count at all. F, J, M, and Q students are exempt individuals for their first five calendar years. While you’re exempt, you stay a nonresident no matter how many days you spend here.
To exclude those days, you must file Form 8843 with the IRS for each year, even if you had no income.
Trap 1: any part of a year counts as a year
The count runs in calendar years, not 12-month stretches. Arrive on August 20, or even December 28, and that whole calendar year is one of your five.
Trap 2: earlier student years count, with no lookback limit
The student rule counts every year you were exempt as a teacher, trainee, or student, however long ago. An undergraduate degree on an F-1 a decade ago, or a J-1 research stint before grad school, uses up years from the same five.
Trap 3: year 6 reaches back to January
In year 6, the exclusion is gone and only year-6 days count toward 183. Most students who stay the full year pass that mark by early July. When you do, your residency starts on the first day you were in the U.S. that year, not on day 183. That’s why many payroll offices start withholding FICA on January 1 of year 6.
Arrival-year cheat sheet
This assumes no earlier F, J, M, or Q years, substantial compliance with your visa each year, and at least 183 days in the U.S. once counting starts.
| First arrived (any date that year) | Exempt calendar years | FICA generally starts |
|---|---|---|
| 2021 | 2021-2025 | 2026 |
| 2022 | 2022-2026 | 2027 |
| 2023 | 2023-2027 | 2028 |
| 2024 | 2024-2028 | 2029 |
Earlier student or exchange years shorten the window. Spending fewer than 183 days in the U.S. in year 6 can push residency back.
The narrow exception past five years
A student past five years can stay an exempt individual only by showing both that they don’t intend to live in the U.S. permanently and that they’ve substantially complied with their visa. The IRS weighs facts such as whether you’ve kept a closer connection to another country and whether you’ve taken steps toward a green card. It’s a judgment call on your specific facts, so get advice before relying on it.
If you do become a resident alien and you work for your own school, a separate student exemption in IRC §3121(b)(10) may still keep FICA off your pay while you’re enrolled and regularly attending classes.
How to check your pay stub and W-2
Start with the stub. Look for a line labeled Social Security, OASDI, or SS, and another labeled Medicare or MED. If you’re in an exempt year and either one shows a dollar amount, something’s off. Our guide to reading your pay stub explains each label, and the pay stub decoder helps you match lines to amounts.
At year end, check your W-2. Box 4 is Social Security tax withheld and box 6 is Medicare tax withheld. For a fully exempt year, both should be blank or zero. How to read your W-2 walks through the other boxes.
Why payroll gets it wrong
Mistakes tend to follow a few patterns:
- The payroll system withholds FICA from everyone by default, and nobody flagged you as a nonresident.
- HR sees an EAD card for OPT and assumes you’re a resident.
- Your five-year history was counted wrong. That can cut either way, and a forgotten earlier F-1 or J-1 stint can leave you exempt longer than the rules allow.
The W-4 doesn’t turn FICA on or off
Form W-4 controls federal income tax withholding only. Under IRS Notice 1392, nonresident aliens check Single or Married filing separately, write “NRA” below Step 4(c), and can’t claim exempt. Writing “exempt” on a W-4 does nothing for FICA, and nonresidents aren’t allowed to do it anyway. Our post on claiming exempt on your W-4 explains what that box does.
You prove the FICA exemption to payroll with immigration documents instead.
What to bring HR
- Passport and visa
- Form I-94 (your arrival record)
- Form I-20 (F-1 or M-1) or Form DS-2019 (J-1)
- Form I-766, the EAD card, if you’re on OPT or STEM OPT
- The I-20 page showing CPT authorization, if you’re on CPT
- A short note citing IRC §3121(b)(19) and the IRS page on foreign student liability for Social Security and Medicare taxes
Tell them the first year you were in the U.S. in F, J, M, or Q status, including any earlier stints, so they can place you on the five-year clock.
See the dollars at stake
For your own number, run your pay and pay frequency through Pay44. It shows Social Security and Medicare as separate lines, and those two lines are what a covered worker pays per check at that salary. For an exempt student, that’s the amount that shouldn’t be leaving your paycheck.
One caution: its federal income tax line uses standard W-4 math, and nonresident withholding runs higher than that (see the last section). For an annual FICA total to size a refund, try the FICA tax calculator.
Getting the money back: employer first, then Form 843
The IRS and Pub 519 give the same order: go to your employer first.
Step 1: ask your employer
For FICA withheld in error this year, the employer can repay you and adjust its own filings. For a prior year, it corrects on Form 941-X and issues a corrected W-2c. Before it can claim that credit, it needs your written statement that you haven’t claimed and won’t claim the refund yourself. If HR asks you to sign something, that’s probably why.
Step 2: file Form 843 with the IRS
If the employer can’t or won’t refund the full amount, file Form 843, Claim for Refund and Request for Abatement. Pub 519 lists what to attach:
- A copy of your W-2
- A copy of your visa
- Form I-94 or other proof of your arrival date
- Form DS-2019 (J-1) or a complete copy of your I-20 (F-1 or M-1)
- Form I-766, if you were on OPT
- Proof of permission to work, if the job was economic-hardship employment
- A statement from your employer showing what it repaid or claimed. If you can’t get one, write your own statement explaining why, or attach Form 8316 saying the employer won’t refund the tax.
- Pay statements for the exempt period, if you were exempt for only part of the year
Form 8316 asks whether the wages were related to your course of studies and whether your employer repaid or claimed any of the tax. The form states that if the wages weren’t directly related to your studies, the tax was correctly withheld and you aren’t entitled to a refund.
Pub 519 gives this mailing address: Department of the Treasury, Internal Revenue Service Center, Ogden, UT 84201-0038. Confirm it in the latest Pub 519 before you mail, since the Form 843 instructions send nonresident students there for the address.
Two filing rules trip people up:
- One Form 843 per tax period. Wrong withholding in two years means two separate forms.
- Additional Medicare Tax doesn’t go on Form 843. That 0.9% tax on wages above $200,000 is claimed on Form 8959 with your return instead. Few students ever see it, but Additional Medicare Tax explained has the details.
Keep copies of everything you send. The IRS doesn’t publish a processing time for these claims, and they can take months.
The deadline
A refund claim is generally due 3 years from when the return was filed or 2 years from when the tax was paid, whichever is later. For FICA, IRC §6513(c) treats a year’s employment tax returns and payments made early as filed and paid on April 15 of the following year. So the clock generally starts on that date.
| Year FICA was withheld | Treated as filed and paid | Claim generally due by |
|---|---|---|
| 2022 | April 15, 2023 | April 15, 2026 (generally closed) |
| 2023 | April 15, 2024 | April 15, 2027 |
| 2024 | April 15, 2025 | April 15, 2028 |
| 2025 | April 15, 2026 | April 15, 2029 |
If FICA was wrongly withheld from your pay in 2023, April 15, 2027 is the date to watch. Your exact deadline can depend on your facts, so don’t wait until the last month.
What the exemption doesn’t change
Federal income tax is still withheld, and it runs higher
Nonresident aliens generally can’t claim the standard deduction, so payroll adds an extra amount to your wages before applying the withholding tables. Under IRS Publication 15-T for 2026, that’s $16,100 a year for a 2020-or-later W-4, or $619.20 per biweekly pay period. The add-on isn’t reported on your W-2 and doesn’t raise Social Security or Medicare.
So your federal withholding will look higher than a coworker’s on the same salary. That’s expected. Students from India are the exception: they can claim the standard deduction under Article 21(2) of the U.S.-India tax treaty, and Pub 15-T excludes them from the add-on.
You still file a return
Nonresident students file Form 1040-NR when they have U.S. income that requires a return, plus Form 8843. If your home country has an income tax treaty with the U.S., you generally claim that benefit through your employer on Form 8233. Treaty benefits are a separate income tax matter and have nothing to do with FICA.
State income tax still applies
The FICA exemption is federal and doesn’t reach state income tax. States tax wages earned there under their own rules, and some ignore federal tax treaties. California’s Franchise Tax Board says the state “does not conform to federal law relating to income protected by U.S. tax treaties.” Living and working in one of the states with no income tax takes this line off your stub entirely.
State payroll programs such as disability insurance or paid family leave follow separate state rules. Check with your state agency or payroll office rather than assuming the federal exemption carries over.
A proposal to watch
The OPT Fair Tax Act (S. 2940), introduced September 30, 2025, would end the FICA exemption for OPT workers. As of September 23, 2026, it’s proposed, not law: it was referred to the Senate Finance Committee and hasn’t been enacted. The exemption described here is current law.

Frequently Asked Questions
Do F-1 students pay Social Security and Medicare tax?
Not while they're nonresident aliens for tax purposes doing work that USCIS allows for the purpose of their F-1 status, such as on-campus jobs, CPT, OPT, and STEM OPT. Once an F-1 student becomes a resident alien, usually in the sixth calendar year, FICA applies even though the visa hasn't changed.
Does the FICA exemption apply during OPT and STEM OPT?
Yes, as long as you're still a nonresident alien. OPT and STEM OPT are practical training, which the IRS lists as qualifying work. DHS says STEM OPT workers generally aren't subject to FICA until after their first five calendar years in F-1 status.
When does an F-1 student start paying FICA?
Generally in the sixth calendar year counting from the first year of F, J, M, or Q presence, if you're in the U.S. at least 183 days that year. Your residency then starts on your first day in the U.S. that year, which is why payroll usually withholds FICA from January 1.
Does arriving late in the year count as a full year?
Yes. The five-year rule counts any part of a calendar year, so arriving on August 20 or December 28 uses up that whole year.
How do I get a refund if my employer withheld FICA by mistake?
Ask your employer first and bring your immigration documents. If it won't refund the full amount, file Form 843 with the IRS and attach your W-2, visa, I-94, I-20 or DS-2019, your EAD if you were on OPT, and either an employer statement or Form 8316.
How long do I have to claim a FICA refund?
Generally 3 years from April 15 of the year after the tax was withheld, because a year's FICA returns and payments are treated as filed and paid on that date. FICA wrongly withheld in 2023 can generally be claimed until April 15, 2027.
Is my F-2 or J-2 spouse exempt from FICA?
No. IRS Publication 519 says work by F-2, J-2, M-2, and Q-3 spouses and children is covered by Social Security, so FICA is withheld from their wages.
Does the FICA exemption mean no income tax is withheld?
No. Federal income tax is still withheld under nonresident W-4 rules, and payroll adds an extra amount to your wages first ($16,100 a year in 2026), so withholding runs higher than for a resident. You file Form 1040-NR and Form 8843, and state income tax generally still applies.
