Hi - I moved from NY to FL in Sept 2020.
I always filed multi-state returns. I worked in NJ and lived in NY.
Now I moved from NY in Sept and my NY return is calculating 100% of my federal income even though only 59% of that income was earned in NY. what am i doing wrong
In the NY state interview you will allocate to NY only the NY portion of wages.
After the residency questions you will arrive at a page titled "Date of last move". You will enter when you left NY and then select an appropriate answer to the status on 31 Dec. I assume it will be "did not live in NY and no NY income while a non-resident." That will open the interview questions to allow an allocation to NY only.
Later in the interview as in prior years you will also have the opportunity to claim a NY credit for taxes paid to NJ while you were in NY. You should complete the NJ non-resident return first to have the numbers you need for the NY return credit.
