Thanks, Vadio and USTAXHELP.
My husband was only in the US for a year on a work visa, so he's perfectly non-resident for tax purposes.
So just to be clear: I need to file a 1040, 2555, 1116, TDF 90-22.1 and 2450 (the last only if I want a time extension).
Assuming I'm a fairly normal person who spent half of the tax year in the US and half in the UK and never came close to having 10k in the bank, with no tax complications at all (welfare, benefits, etc.), that should be everything, yes?
Thanks again.
