Please help as I need some expert advice. I was working as an employee who received commission/bonus income. Unfortunately my employer did not pay fica for the commission/bonus income. The first commission I received he did not issue any tax documentation and I went to tell him that I planned to pay my income taxes and wanted to know where I was supposed to put it. He told me to place it under "other income". I did pay income taxes on this and did pay a penalty for not withholding enough taxes. After this I received both w-2s & 1099s. I paid income taxes on all of this money and continued to put the commission under "other income", however I did not pay fica except for 2006. (When I realized I was supposed to put the 1099 income unto a schedule c, I did for that for 2006.) I filed an SS-8 for all these years. The IRS determined that I was not an independent contractor & was an employee for all of the years. The IRS has asked me to fill out unreported tip paperwork for all of the years. Do I have any recourse to limit my fica & penalties? I am trying to do what was right for everyone, but I don't want to be penalized excessively for my employer trying to skip out on his tax obligations. I appreciate any insight that anybody can provide. Thank you.
