Thanks for the info, mamas. I definitely made below that amount every year I lived abroad. Oh brother, now I am going to have to back file. I checked out the irs website, I'm still going through it. I know someone here who had to back file, too, so I know it can be done, it's just going to be a big hassle. Thank god for EZ forms, I wish the Czech Republic had them, filing taxes here is a nightmare. A couple of years ago, the forms the government published were so difficult to understand that they had to fire the team that wrote them!
