What to do with form 1042-S, when filing as a resident alien?
I am a foreign postdoc, working at an American University. I received (2013) W2 and 1042-S forms (the latter with Inc. code 18); I understand that 1042-S is intended for non-resident aliens. For tax year 2013, however, I meet the substantial presence test and so do my dependents; moreover, in my case, filing as a residential alien (thus using 1040A) would be advantageous. I assume, however, that if I use form 1040A, the amount listed on the 1042-S (box2) will NOT be subject to withholding tax. If my assumption is correct, then I have the following question: is it OK if I calculate my income (wages, salaries) by summing the amounts listed on the W2 form (box1) and the 1042-S form (box2), and report this on line 7 of the 1040? If so, do I attach both forms to my tax return?
