The situation is this. A person living in CA was laid off in November, 2009; however, he was kept on the payroll through Jan 31,
2010 (i.e., for payroll and benefits purposes, he was still considered an employee; the main impact of this was that he couldn't file for Unemployment Compensation until Feb 1, 2010).In late December, 2009, he moved to NC, so by Jan 1, 2010, he was no longer a resident of CA, although his employer continued to withhold CA income tax. My question is whether he owes any CA income tax on the pay he received in 2010.
A scenario I was thinking of that could screw him is this. He files a CA non-resident return claiming he did no work in CA during 2010, thus he owes $0 income tax and requests a refund. He also files an NC resident return. Sometime later CA denies that he has $0 CA income, assesses income tax, and he then finds it's too late to claim a tax credit against his NC return (based on the difference in rates between NC and CA, he estimates around 35% of what he pays CA can be taken as a credit against his NC income tax).
