@tuck0066 , you are correct in that if the figures you provided -- your gross Foreign Income is all excluded per form 2555 and your ONLY US income is approx. 1000, then your world tax liability should be zero. I was assuming that you had some residual /un-excluded FE income that could have resulted in a small residual US tax liability.
Assumimng that you are using Windows download version ( such as Home & Business ), and you can go into forms mode look at the forms involved -- 2555, 1040 and Foreign EI tax worksheet. These should be enough to see where TT is getting the "due " amount. I would be most interested in what is wrong.
