I have a client that lived in New Jersey until sept. 2021.  His only source of income is a w-2 from a new york company and has ny taxes withheld. Prior to 2021 he filed a non resident NY return and a NJ resident return taking credit for the taxes paid to NY on his NJ return.  Since he moved to Florida in September 2021, only has NY income, I think he does not need to file a New Jersey tax return.  

I'm I correct?
