Thank you for your reply! Yes, I also realize that Box 16 value on W2 form ends up not mattering in my CA part-year resident (I moved to MA last Sep) tax form (540NR form). But 540NR form's Box 12 asks for "Total California wages from your federal Form(s) W-2, box 16", even though for some reason it seems like it never gets used. So, I am wondering if the CA tax agency will think it's a bit odd that there is a discrepancy between Box 12 (CA income reported on W2) and Box 32 (CA adjusted gross income from Schedule CA (540NR), Part IV, line 1), and also the CA tax withheld shown on W2 is calculated assuming that my CA income is equal to my federal income, even though CA income shown on W2 is less than my federal income (they only updated my remote work status for withholding the CA tax but forgot to do so for calculating the CA income tax). @BillM223 or anyone else.
