Question about bonus I received when I'm a nonresident of NJ
I have a question about the New Jersey source income. When I was a florida resident, I worked for a NJ employer remotely. so the wages I earned during the days I'm in Florida are not included in my NJ income. However I received my sign-on bonus with that paycheck. Although I was not in NJ, my employer think the bonus is sourced to NJ so they included the bonus amount alone to my NJ income and also withhold tax for that bonus. In this case, is it considered that I received NJ income when I'm a non-resident so that I need to file NJ-1040NR?
