Is she working remotely for a CA employer?   Or did she find a different employer in WA?  Why do you think she needs to pay CA income tax if she lives and works in WA?   Merely having a CA driver's license does not necessarily dictate that she has to pay CA tax on earnings she received in another state.  And WA has no state income tax.   And..."Texas for a couple of months..."   Texas does  not have state income tax either.

We need to understand whether your daughter was or will be receiving California-sourced income.   It is not at all clear why she had income from TX or why she has a CA driver's license and auto registration.   

In addition, you say she will likely live in WA for a year or two....please read the information about the laws in WA pertaining to getting a WA driver's license when you move to WA.

@ihtblzr if she physically worked and lived in WA, she pays state taxes there.  sounds like a part year resident for 2023. 

What income, if any did she earn while physically working and dliving in CA? 

is this a W-2 job or a self-employed? if self-employed , is the "employer" / client  in CA?

Careful ... there are rules when you make a move ... a DL needs to be gotten in the new state usually within 30 days ...  https://www.dol.wa.gov/moving-washington-wa/moving-washington-get-driver-license#:~:text=You%20have%....

Note to other users of the forum---for some inexplicable reason, the original poster @ihtblzr has removed their question----the question was in regard to a recently divorced daughter who moved to WA---for possibly one or two years, but who had a CA driver's license and auto registration.   The OP was asking if their daughter should have CA tax withheld, but had not explained whether daughter's income was CA-sourced, or if daughter's income was sourced from jobs in TX and WA.
