A nonresident alien (NRA) needs to report Non-Effectively Connected (NEC) income on schedule NEC of Form 1040-NR. The income will bypass the AGI but separately taxed. As such the income will not flow to the state, how do we solve the problem?
The question can be divided to two sub-questions.
First of all, it is a theoretical question: Is the NEC income subject to state tax?
I could not find direct answer from state's instruction. I guess the instruction does not cover every odd case, but by reasoning I would say yes, as far as the state is concerned, for the most part, an NRA for federal purpose is a normal resident if she lives in the state full year and is subject to the same rule as any other resident. Am I not right. [There are special cases with federal treaty, some states recognize like MN and some do not like CA].
The second question is a technical question: how do I get the income flow to the states?
An easy way would make adjustments, I cannot do this for CA but not for MN which requires MN AGI to be the same as federal for the purpose of E-file.
The second way is to file a "dummy" resident return for federal.
The third way is to paper file.
I would like to hear if you have the issues, and how do you deal with it.
