I lived in NM for 5 months and was transferred to Texas for work. My W-2 shows a federal income amount in box 1 and a state income (which is different) in box 16. Looking at the numbers, it sounds correct because only half of my wages were in NM and the last half of the year was in Texas. TurboTax seems to be taxing me on my full federal amount and when I get to the end of the program and check the return for errors, it keeps telling me that my numbers in my W-2 are incorrect and that I need to correct them so that both the federal and state amounts match. Can you help me?
There are two points to cover. First is the NM definition of "part-year". NM states:
You are a New Mexico part-year resident if you meet all of
• You were a New Mexico resident for part of the year.
• You were not physically present in New Mexico for 185
days or more.
• On December 31, you were no longer domiciled in New
Mexico and you had moved to another state, intending
to maintain domicile status in that other state.
Part-year residents who change domicile during the year
are not residents of New Mexico for income tax purposes for
periods when the taxpayer’s domicile is outside New Mexico.
If you do not satisfy those requirements, your total income is subject to NM income tax.
If you do satisfy those requirements, what NM does is first have you report your full income and then, for part-year and non-residents the calculated tax is, with some adjustments, reduced to the fraction of income earned in NM.
So in either case, you need to report the total income for both the federal and state.
