The following information will help you apply for a money refund.
Employers withhold different kinds of taxes.
This tax tip focuses on box 4 and box 6. If the employer cannot or will not issue the refund, there is a special procedure you can use to obtain a refund of Social Security and Medicare Tax. This procedure is entirely separate from filing your income tax forms. It includes two special IRS forms, Form 843 and Form 8316. You will be required to show on the forms that you attempted to contact your employer first.
