My startup is not public but I have received a grant for RSUs that vest at IPO. I understand that when that happens I will owe income tax, but I am not sure which state can claim that tax. In particular, suppose I worked in New York for a couple years after the grant before moving to a lower income-tax state and suppose that the IPO happens after I've moved to the lower income-tax state. Do I owe taxes to NY or my new home state?
