OPT and CPT FICA refund calculator

Last updated 2026-10-22

Short answer

If FICA was withheld from wages that were exempt, the employee share is 7.65% of those wages and the employer paid a matching 7.65%. Ask the employer to refund first; if it will not, the IRS claim is generally Form 843 with Form 8316.

Some employers withhold Social Security and Medicare from students who are exempt. Enter the wages paid in the exempt period to see the amounts at stake and the usual path to recover them.

Worked example

Wages of $60,000 in the exempt period mean $4,590 withheld from the employee and $4,590 paid by the employer, $9,180 in total.

For staffing firms

An employer that withheld FICA in error can usually correct it and recover its own share. Keeping work authorization and visa category on each candidate profile helps payroll apply the right treatment from the first paycheck.
