Not sure what you mean by the employer being "exempt" or how you expect to become exempt from paying Social Security or Medicare.
Are you working as an independent contractor for a person or business that is not withholding tax, Social Security or Medicare? If so, you have to file as self-employed and pay self-employment tax to pay your own Social Security and Medicare.
What kind of document is your income being reported on? Did you receive a 1099NEC or 1099Misc? Or a W-2?
