State tax filing

Not entirely.  Calculate the number of months from grant date to vesting date.  Then divide the number of months allocated to NY by the total number of all months (i.e. from grant date to vesting date) and the resulting percentage is what you can allocate to NY.  For example, let's say the number of months from grant date to vesting date was 12 months.  Let's also say that for 9 of those 12 months you were in NY.  For the final 3 months in this example you were in CA and the RSUs vested on the last day in the 12th month.  You would then divide 9 by 12, and the resulting percentage is 75%.  Therefore, in this example, allocate 75% of the RSU income to NY.  The remaining 25% is allocated to CA.
