Step 1: Contact Your Employer (Fastest Route)

Before filing with the IRS, you must ask your employer to refund the mistakenly withheld FICA taxes. Many corporate payroll departments (using systems like ADP or Workday) can reverse the transactions and issue a corrected W-2c statement immediately. This is the fastest way to get your money back.

Step 2: File IRS Form 843 and Form 8316

If your employer refuses to refund the taxes, or if you have already left the company, you can file a refund claim directly with the IRS. You must mail a paper packet containing the following forms and documents:

  • IRS Form 843: \"Claim for Refund and Request for Abatement\". Use this form to state the exact refund amount calculated above.
  • IRS Form 8316: \"Information Regarding Request for Refund of Social Security Tax Erroneously Withheld on Wages Received by a Nonresident Alien on an F, J, or M Type Visa\". This form confirms your student visa details and employer's refusal.
  • Copy of W-2: Copy of the W-2 showing the FICA withholdings.
  • Copy of Forms I-20: Proves your active study authorization dates.
  • Copy of Form I-94: Your official travel history arrival/departure record.
  • Copy of Visa and Passport: Copy of your passport data page and F-1 visa stamp page.
  • Employer's Refusal Statement: A letter from your employer confirming they withheld the tax but cannot/will not refund it, or a statement confirming you were unable to obtain a refund from them.

Where to Mail the IRS Refund Packet?

Collate your documents, sign the forms, and mail the complete physical packet to the IRS service center corresponding to your state. You can verify mailing addresses on IRS.gov (typically sent to the Department of the Treasury, Internal Revenue Service Center, Ogden, UT 84201-0038).
