Some guys aboard ship once tried this amtrak law and saved a ton of dough but something makes me think they got their ass in a wringer and had to pay it back. true, we were in international waters a lot with over 250 das per year but I don’t think it worked for them. Even if it did, if there is any chance it isn’t 100% I wouldn’t do it as I’ve been in trouble with the irs before and will not do it again… just pay the money.
I didn’t pay taxes for a year though when I was in SW Asia… not sure it was worth it !!!
