I, too, got a call yesterday afternoon from a client whose files were in the dead files, not literally. I haven't seen him since 2007 when I filed an extension for 2007. He wanted me to file an extension for 2010. He hasn't filed since 2007..oh, boy....in our discussion...by the way, I got married Sept 2010. Well, then we have to file either MFJ or MFS...He said no no single...how is this, I said. well, her tax preparer filed her single because I didn't have my stuff ready...how did he do this??? How do you file single when you are married? I suppose file single then amend later, but doesn't that admit the previous one was totally incorrect. Any thoughts?
