Someone I know hasn't filed taxes since 2014 and would like to catch up starting with his 2015 federal and California returns. He's not, shall we say, tax savvy, and would like me to do his back taxes.
I understand it's too late for him to get a refund for the earliest years. (I have no idea whether he owes or was owed.) But I can still use those old versions of TT Desktop for Windows to prepare his paper returns, right? I just reinstalled TT2015 Premier on my Win10 laptop and Federal seemed to install and update just fine. I haven't tried to load CA yet.
