After you file

@VolvoGirl Thank you for responding to this thread.

 

Yes, I'll be following this method and helping him file this year. 

 

Any guidance on amending returns? Also, if I do pay the FICA taxes for the previous years, will the now applied Social Security and Medicare credits automatically be reported from the IRS to the Social Security Administration ... or would I have to do fill out some other paperwork as well? Apologies, as I type this, I realize this is getting more and more complicated ..
