Is It Possible to Remove Social Security and Medicare Taxes
Yes, if one fills out their FIRST W-4 when starting a new job, one can sign WITHOUT a Social Security Number; however, once an employer has this information, they are required to deduct SSI and Medicare taxes in the future, even if a subsequent [updated] W-4 does not use a SSN. Even if an employer refuses, one can still receive the tax withholdings back.
Tax returns may not declare the SSI and Medicare withholdings to be redeemed lawful money. This can lead to the IRS agent/attorney declaring the entire return frivolous. One is wise to consider all withholdings toward other "amounts" than what would be on the basic "take home" pay as premiums toward an insurance claim. We like to call Social Security "Old Age Insurance". Treat it like car insurance - one cannot claim premiums so they are refunded just because one never got into an accident and made a claim!
NOTE: The Social Security Administration CANNOT remove one's SSN unless US Citizenship is rescinded - and we DO NOT recommend this!
