I've filed for an extension every year and no *knocks on wood* audits so far...I heard that as long as you still owe them money (and that seems to be my "thing" - lol) that you don't have to worry AS MUCH about an audit. I dunno...I think they see me as a "sure thing" every year so they feel sorry for me and leave me alone....
Who knows? It's like the Grim Reaper...when it's your time to go, it's your time to go....
Happy Tax Day All!
