State tax filing

Hi Thomas, 

 

I have the same situation, and am wondering if the 'Nonresident Subtraction from Income Tax' in the summary table of NJ nonresident is incorrect. My first company is in NY, and the second company is in NJ. I live in NY for the whole year. Should 'Nonresident Subtraction from Income Tax' within NJ nonresident file be (amount earned in the NY * marginal tax rate in NJ) ? Right now, the summary seems to use the portion of NY earnings directly (close to the first company's earning / total earning for the whole year), which underestimates the return from NJ nonresident.  Is my understanding incorrect? Thanks.
