If your stock options were exercised, you now are a shareholder and you pay taxes in the state of residence at the time of sale. If you don’t live in California (for real) then they aren’t going to be able to tax you on the sale. RSUs with a double trigger on IPO will still be taxed on vesting as if you were in CA.
