Potential FICA Overpayment Warning: Qualifying nonresident F-1, J-1, and M-1 students can be exempt from Social Security and Medicare taxes on certain authorized employment. Eligibility depends on tax residency, visa status, employment authorization, and the purpose of the employment. This is not an automatic 0% rule for every F-1 or J-1 worker.

2026 FICA Rates
- Social Security: 6.2% employee rate.
- 2026 Social Security wage base: $184,500.
- Medicare: 1.45% employee rate with no wage-base limit.
- Additional Medicare Tax: employers begin withholding an additional 0.9% from an employee's wages once wages exceed $200,000 during the calendar year. This simplified refund calculator does not calculate Additional Medicare Tax.
If the wages were genuinely exempt from FICA, the potentially refundable employee withholding should be based on the actual Social Security and Medicare taxes withheld, not automatically on 7.65% of all gross wages.
Statutory Regulations & Step-by-Step Claim Procedure
Under Internal Revenue Code §3121(b)(19), certain services performed by nonresident aliens temporarily present in the United States in F-1, J-1, M-1, or Q status can be exempt from Social Security and Medicare taxes when the applicable statutory requirements are satisfied. For students, qualifying exempt employment can include certain on-campus employment, authorized off-campus employment, and practical training. The exemption is subject to tax-residency, immigration-status, employment-authorization, and purpose-of-visa requirements.
Step-by-Step Refund Process:
- Request Employer Refund First: Contact the employer or payroll department that withheld the Social Security and Medicare taxes and request a refund. If the employer corrects the withholding, a corrected Form W-2c may be issued as applicable.
- File the IRS Claim if Necessary: If the employer cannot or will not provide the full refund, file Form 843 and, where applicable for a nonresident-alien F, J, or M visa claim, Form 8316, together with the supporting documentation required by the IRS. This can include the W-2, I-94, I-20 or DS-2019, passport/visa information, and documentation concerning the employer's refund or refusal.
- Submit the Claim Using Current IRS Instructions: Use the current Form 843 instructions and applicable Form 8316 instructions for the correct filing address and submission requirements. Mailing addresses can change, so the page should not hard-code a permanent address without current verification.
FICA Tax Exemption Rules Summary
| Visa Status | Exemption Period | Statutory Citation |
|---|---|---|
| F-1 / M-1 Student (qualifying authorized employment / practical training) | Generally applicable while the student qualifies as a nonresident alien and meets the exemption requirements; student substantial-presence rules generally use a 5-calendar-year period | IRC § 3121(b)(19) |
| J-1 Student | Generally applicable while the student qualifies as a nonresident alien and meets the exemption requirements; applicable calendar-year limitations must be considered | IRC § 3121(b)(19) |
| J-1 Scholar / Researcher | Separate exchange-visitor rules apply; do not automatically apply the student five-calendar-year rule | IRC § 3121(b)(19) and applicable IRS guidance |
| H-1B / L-1 Work Visas | Generally subject to standard FICA rules unless another specific statutory exception applies | Standard FICA Tax Rules |
Separate student FICA exception: IRC §3121(b)(10) can exempt qualifying services performed by a student employed by a school, college, or university where the student is enrolled and regularly attending classes. This exception is separate from the nonresident-alien visa exemption and can potentially apply even after a foreign student becomes a resident alien. Off-campus employment generally does not qualify under this separate student exception.

Frequently Asked Questions (FAQ)
Under IRC §3121(b)(19), certain nonresident aliens temporarily present in the United States in F-1, J-1, M-1, or Q-1 status may be exempt from Social Security and Medicare taxes on compensation for services performed to carry out the purpose for which the visa was issued. For qualifying students, exempt employment can include certain on-campus employment, authorized off-campus employment, and practical training. The exemption does not apply to every job merely because the worker holds one of these visa classifications.
For qualifying F-1, J-1, and M-1 students, the special nonresident-alien student FICA exemption generally applies during the applicable period while the individual remains a nonresident alien and the other requirements are satisfied. The substantial-presence student exemption generally uses a five-calendar-year rule, subject to the applicable exceptions and limitations. J-1 teachers, trainees, researchers, and other exchange visitors have separate rules and should not be treated as having the same five-year student rule.
Step 1: Contact the employer that withheld the Social Security and Medicare taxes and request a refund. If the employer cannot or will not provide the full refund, Step 2: file an appropriate claim with the IRS using Form 843 and, where applicable, Form 8316, together with the supporting documentation required by the IRS. A corrected Form W-2c may be needed when the employer corrects the withholding.
If an employer cannot or will not provide the full refund, an eligible claimant generally files Form 843 with the applicable supporting documentation. For nonresident-alien F, J, or M visa claims, Form 8316 may also be required. Supporting evidence can include the Form W-2, I-94, applicable Form I-20 or DS-2019, passport and visa information, and evidence concerning the employer's refund or refusal. The IRS instructions should be followed for the exact claim.
IRS processing times for Form 843 claims can vary and are not guaranteed to take a particular number of months. The IRS should be treated as the authoritative source for current processing information. A refund claim should not promise a particular processing time or statutory interest unless the applicable law and IRS determination support it.
Potentially. Authorized practical training employment, including qualifying OPT employment, can be exempt from FICA when the individual remains a qualifying nonresident alien student and the employment is permitted and closely connected to the purpose for which the visa was issued. STEM OPT does not create an automatic FICA exemption by itself; the applicable immigration and tax-residency requirements must still be satisfied.
No. The FICA exemption depends on the applicable visa classification, U.S. tax residency, authorization of the employment, and whether the services are performed to carry out the purpose for which the visa was issued. Employment that is not authorized or is not sufficiently connected to the visa purpose may not qualify.
Potentially. The special nonresident-alien exemption generally becomes unavailable once the student becomes a resident alien, but IRC §3121(b)(10) provides a separate student FICA exception for qualifying students employed by a school, college, or university where the student is enrolled and regularly attending classes. Off-campus employment generally does not qualify under this separate student exception.
For 2026, the employee Social Security rate is 6.2% on wages subject to the $184,500 Social Security wage base. The employee Medicare rate is 1.45% on all covered wages, with no wage-base limit. Additional Medicare Tax withholding of 0.9% can apply to wages above $200,000 paid by an employer during the year.
No. Qualifying practical training can be exempt, but the individual must satisfy the applicable nonresident-alien, visa, authorization, and purpose-of-visa requirements. The label CPT or OPT alone does not establish FICA exemption.
The IRS instructs taxpayers to seek the refund from the employer first. If the employer cannot or will not provide the full refund, an eligible claimant can generally file Form 843 and, for applicable nonresident-alien F, J, or M visa claims, Form 8316 with the required supporting documentation.
No. This calculator estimates the amount of employee Social Security and Medicare tax that could potentially be refundable if the wages were exempt. It does not determine immigration status, tax residency, visa compliance, employment authorization, or final legal eligibility for the FICA exemption.
