CA tax law is that the non-military spouse of an active duty servicemember who is domiciled in CA but stationed outside CA due to PCS orders, is herself considered a non-resident of CA for tax purposes. As such, she is subject to CA income tax only on CA-source income. Income earned from work performed in HI is not CA-source income.
See "Non-military spouse" on page 6 of this CA tax reference:
