State taxes

[lschneider04]

If I pay state tax in Calif, but file in Washington that has no state tax. What do I do

[TomD8 · Accepted solution]

In which state do you live?  In which state do you work?

Live in Washington, pension comes from Calif, they withhold state tax, file in Washington, they have no state tax. Do I have to file in Calif?  

[TomD8]

If you were a resident of Washington all of 2020, and your only income from California was your retirement income, then that income is not taxable by California.  
However, you would have to file a non-resident California tax return, allocating zero income to CA, in order to receive a refund of the withheld CA taxes.

Retirement income is taxable by your state of residence at the time you receive it.
