State tax filing

steofn3 · ‎September 29, 2023

I moved to NJ in August 2022 to work in NY. I lived in Indiana before that. I know that NY requires all income to be reported in W-2.

My Situation (example):

IN Income until 8/8/2022 = 55,000
<move to NJ on 8/9/2022>
NJ Income = 45,000
NY State Income as shown on W-2 = 100,000 (because it requires all income to be reported)
Amount taxed by NY State = 90,000 (as shown after I did my NY taxes)
Allocated NY State tax = 5000 x (income factor) = 2300

When filing for NJ taxes, it asks "Double-taxed income while a resident of New Jersey" and "Taxes paid to New York".

Question: how to determine double-taxed income while a NJ resident? The amount taxed by NY (90,000) also contains Indiana portion. What needs to be done here?
