Which state gets to tax a paycheck when moving between pay dates?

[anonymous2]

Example:

Pay period of February 15->February 31st. Check deposited to my savings account on February 30th.

I leave state A on February 23rd. Resident of State B on February 26th.

Which state has a claim to tax my paycheck. Is it state B as I'm resident at the time of check payout. Or is it stateA as I've worked there for most of the pay period?

thanks

In general, the state where you actually perform the work can tax the income.  Your resident state can also tax the income, but if the work was performed in a nonresident state, you can get a credit for the taxes paid on the double-taxed income.  You will be able to allocate the income based on WHERE you worked, even if your payroll department did not update the withholding in time.
