F-1 and OPT FICA: A 2026 Year-End Payroll Check

Editorial archive date: 2026-10-26. Researched and prepared November 3, 2026.

A fall payroll check can catch a question about the F-1 OPT FICA exemption before year-end forms arrive. Social Security and Medicare are separate from federal income tax. Review their paystub lines individually and gather the facts that explain your tax residency and authorized employment.

Check whether the visa-based exemption applies

IRS guidance provides a Social Security and Medicare exemption for qualifying nonresident F-1 students performing authorized services consistent with their admission purpose. Students who become resident aliens for tax purposes generally lose that visa-based exception, although other employment-specific exceptions may need consideration.

Label your records by employer and employment period. Campus work followed by an OPT job should not be treated as a single unexplained paycheck history. For each employer, put the authorization document and first paystub together so the payroll question has a clear starting point.

Ask the employer before requesting an IRS refund

If tax appears to have been withheld incorrectly, the IRS directs students to seek a refund from the employer first. If the employer does not provide a full refund, the IRS process can involve Form 843 and supporting records, including Form 8316 as applicable. Check the current instructions for the required package.

• Identify the affected Social Security and Medicare amounts.
• Send payroll a concise written question with relevant dates.
• Keep the employer’s explanation and any correction records.

Avoid mixing refund routes

Keep an income-tax refund question and a FICA refund question in separate notes. If payroll sends a correction, check which tax it addresses. Save a copy in your year-end folder and ask whether another document will follow, so you can reconcile the records when preparing the return.

Frequently asked question

Does OPT automatically make every paycheck exempt from FICA? No. Tax residency and the qualifying employment conditions matter. Confirm those facts before requesting a correction.

What to do next

Review one paystub now and raise any FICA question with the employer while the employment records are readily available.
