Can an employer force you to pay fica?
In rare cases where the employer cannot deduct FICA from your salary (for example, you work mostly on tips and your salary is less than what you owe for FICA), your employer will simply report the uncollected amount to the IRS on your W-2 and whether you pay or not is between you and the IRS. Similarly, if you have unreported tips or self-employment, your employer will not get involved in whether or not you pay.
