I started a new job in WA on Dec 1, 2015. My family, all dependents, were in NJ until Jan 15, 2016 -- that's when the movers came and emptied the apartment. All flew to WA on Jan 16, 2016. Do I need to file NJ state tax return for the two weeks in 2016? I am not clear on how residency is determined. 100% of income in 2016 was earned in WA state.
