I spent all of 2010 living in Europe, so for 2010, I filed in both the US and the foreign country, paying the latter a ginormous sum of money. Both returns were prepared by an accountant, and I took the entire FEIE (my income was around $130k), and a foreign tax credit for the rest, so I obviously owed the US zero in 2010. In 2011, I returned to the US.
I'm now preparing my 2011 return, and I am reading about carry forward of unused foreign tax credits. Obviously, I have unused foreign tax credits from 2010 since US rates are lower than the other country's, but can they be used to reduce my US tax in 2011?
Because I stayed in the foreign country for less than half of 2011, I do not owe the foreign country any tax at all for 2011. Does that mean the credits can't be used? From my (admittedly very cursory) reading of Pub 514, it sounds like carry forward of foreign tax credits can only be done if one has foreign earned income subject to foreign tax, which I do not have.
If carry forward were possible, I'd probably engage an accountant again this year, but I suspect that it's not permitted. Am I wrong on that score?
