How do I divide nonresident/part-time resident income between 2 states?
I cant figure out how to calculate a part-time resident income for my daughter-in-law who got married last year in the middle of the year. She started a job in Missouri in June after graduating from college. She was living with her parents in Kansas at the time. One month later she got married to my son and moved in with him in Missouri. Do I need to split how much she made in the time frame she was living in Kansas versus Missouri? Also, she did not change her address on her W2 form when she moved so her business took taxes mainly for Kansas for the whole time frame. Does this have to be corrected?
Thank-you in advance for any assistance/advice
