Those payroll deductions are the worker side of FICA taxes, which equal 7.65% of wages. For many international students, the mistake shows up first on a W-2 and then on a paycheck that is smaller than it should have been. According to analysis by VisaVerge.com, many students recover money that was withheld by error.

The first thing to know is that F-1 students are treated as nonresident aliens for tax purposes during their first five calendar years in the United States. A partial year counts as a full year. That rule matters because it controls whether FICA should have been withheld at all.

During that five-year period, wages from authorized work are exempt from FICA. That includes on-campus jobs, Curricular Practical Training, Optional Practical Training, STEM OPT, and severe economic hardship employment. The exemption comes from Internal Revenue Code Section 3121(b)(19). The separate student exemption under Section 3121(b)(10) applies after five years only when the student works for the school and remains enrolled at least half time.

The payroll error students see first

The problem often starts with an employer that knows how to run payroll for U.S. workers but not for F-1 visa holders. Boxes 4 and 6 on the W-2 show Social Security and Medicare withholding. If those boxes are not blank during an exempt period, the student should act fast.

The IRS expects the student to ask the employer for the refund before filing directly. That step matters. Employers can correct payroll records, issue a Form W-2c, and return the worker’s share of the tax. Many human resources teams comply once they see the passport, I-94, and I-20.

The student should send a written request and keep copies of every email, letter, and date. If the employer refuses, the next step is direct filing with the IRS. The refund claim is separate from income tax filing and does not go on Form 1040-NR.

How the employer refund path works

Start with payroll or human resources and attach the W-2. Include a copy of the passport with the F-1 stamp, the I-94 record, and the I-20 showing work authorization. Ask for the 7.65% worker share to be refunded and request a corrected W-2c.

Analyst Note
Start by asking your employer to correct payroll errors. Provide your W-2, passport with F-1 stamp, I-94, and I-20. Request a W-2c and a refund of the 7.65% withheld as soon as possible.

If the office does not respond, send a formal written request citing IRC Section 3121(b)(19) and give a short deadline. If there is still no action, the IRS can be asked to contact the employer. This route often resolves the issue without a longer filing fight.

That path is also the fastest. When employers cooperate, refunds are often returned within weeks. Students working for more than one employer should repeat the process for each job, because each payroll record stands on its own.

Filing Forms 843 and 8316 with the IRS

When the employer will not refund the tax, the student files directly. The IRS wants a stand-alone claim. It should not be bundled with an income tax return. The main filing pair is Form 843 and Form 8316.

The packet should include W-2s showing the withholding, the passport page with the visa stamp, the I-94, the I-20, and the student tax ID number. A written explanation should describe every attempt made with the employer. If there was a partial refund, that should also be shown.

Form 843 asks for the amount claimed, the tax type, and the reason. Students usually write that they were nonresident aliens in F-1 status, present for fewer than five calendar years, and exempt from FICA under the law. Form 8316 supplies the visa details and the basis for the refund claim.

Mail the claim to the Internal Revenue Service, Austin, TX 73301-0215. One claim should cover one employer and one tax year. If the student wants refunds for earlier years, separate claims are needed for each year. Claims must be filed within three years of the tax year.

Timelines, records, and missing paperwork

Processing usually takes 12 to 16 weeks. That is the normal wait while the IRS reviews documents and checks whether the withholding really was in error. Students can follow up with the IRS Nonresident Alien Unit at 267-941-1000.

Lost documents do not end a claim. Pay stubs, a supervisor letter, or an employer statement can help show where the job was performed. School offices often provide enrollment proof. A student who needs wage records can request an IRS transcript with Form 4506-T and add a short sworn statement explaining the missing paper trail.

When the exemption ends

After five calendar years, the standard nonresident exemption ends. Many students then become resident aliens under the Substantial Presence Test. At that point, FICA usually applies unless the student qualifies for the separate half-time school employment exemption.

Important Notice
If the employer won’t refund, don’t delay. File Form 843 and Form 8316 with the IRS within three years of the tax year, and include all supporting docs. Late claims risk denial and longer wait times.

That shift matters for students on long programs, extended OPT, or STEM OPT. A visa stamp can expire while tax status continues under the rules. An expired F-1 visa does not end the FICA exemption by itself. The tax test and the visa stamp are not the same thing.

Spouses on F-2 status do not receive this payroll tax treatment. Self-employment income also sits outside the exemption. A student who works as an independent contractor on a 1099 generally owes self-employment tax instead of regular payroll withholding.

What students should watch on each paycheck

  • Check Box 4 for Social Security tax.
  • Check Box 6 for Medicare tax.
  • Compare the amounts against the 7.65% employee share.
  • Save every pay stub and every W-2.
  • Keep the I-20, I-94, and passport pages together.

Those records make the employer claim or IRS filing much easier. They also help if the student changes jobs, moves states, or files for prior tax years later on.

Why the refunds matter now

For many students, the withheld amount is not small. On a modest campus salary, FICA can take away hundreds of dollars over a year. That money often goes toward rent, tuition, books, or travel home. Recovering it can ease pressure during a tight semester.

The rules have stayed stable, and IRS guidance continues to point to the same exemption framework. The official IRS page on foreign students and scholars explains the tax treatment for international students and workers. For students on an F-1 visa, the key is acting quickly, keeping records, and filing the claim in the right order.

→ Common Questions
Are F-1 students always exempt from Social Security taxes?+
No. F-1 students are generally exempt for their first five calendar years in the U.S. After five years, they usually become ‘resident aliens’ for tax purposes and must pay FICA taxes unless they qualify for the student exemption by working for the school they attend.
What should I do if my employer refuses to refund the FICA tax?+
If your employer refuses, you must file Form 843 and Form 8316 with the IRS. You should include a written statement explaining your attempts to get a refund from the employer and provide copies of your passport, visa, I-94, and I-20.
Can I claim a FICA refund on my Form 1040-NR?+
No. FICA tax refunds cannot be claimed on your annual income tax return (Form 1040-NR). They must be filed separately using Form 843.
Does this exemption apply to CPT and OPT employment?+
Yes. Wages from authorized CPT, OPT, and STEM OPT are exempt from FICA taxes as long as the student is still considered a nonresident alien for tax purposes (usually within the first five calendar years).
How long does it take to get a refund from the IRS?+
The IRS typically takes 12 to 16 weeks to process FICA refund claims for international students. You can check the status by calling the IRS Nonresident Alien Unit.
