If you move to CA, you need to pay state tax on your entire earnings, not just your raise. 13.3% of 140k is more than 18k, which is certainly significant.
I believe you can deduct state from federal tax, which would save ~2.5% in marginal tax. In addition, social security phases out at ~120k so that's another 7.5% savings. So the difference is almost a wash if I understand correctly?
Don't forget about AMT. That usually throws a wrench in things.
