If CA is your SLR but you are not stationed there and you have no other CA income to report then you don't need to file a CA return at all unless you had CA taxes withheld. File a non resident CA return to get back any taxes you had withheld. Once the CA return you have already filed has fully processed then you can amend the CA return to switch to a non resident. The amendment process opens up later this month.
Your domicile
If your domicile is California, we consider you a resident, and you pay tax on all income while permanently stationed here.
If you come to California because of permanent change of station (PCS) orders, you do not become a resident. Generally, you are a resident of the state from which you entered the military.
Domiciled in California
Your domicile is the one place:
- Where you maintain a true, fixed and permanent home
- To which you intend to return whenever you are absent
Temporary Duty assignment (TDY)If you leave California under a TDY, you will continue to be a California resident.
Home portIf your home port is in California, you remain a resident while on sea duty, regardless of the ship’s location.
Stationed outside of CaliforniaAn individual domiciled in California when entering the military is considered a nonresident while stationed outside California on permanent change of station (PCS) orders.
We tax nonresidents on California sourced income.
