California taxes for military in San Diego: who pays, who doesn't

California taxes are the first thing many families worry about when PCS (permanent change of station) orders say San Diego. For most active duty members the answer is simpler than the rumors: what matters is your domicile, your legal state of residence, not where you are stationed. This guide summarizes the California Franchise Tax Board's (FTB) 2025 Publication 1032 and related state and federal sources, checked October 5, 2026. It is general information, not tax advice.

1. Stationed here, legal resident somewhere else

The SCRA (Servicemembers Civil Relief Act) keeps your domicile where it was when you joined or last chose it, even after years in San Diego. FTB Publication 1032 states it plainly: service members who are not domiciled in California are not taxed by California on pay for military service performed here.

The exception is other income from California sources. Per Pub 1032, a nonresident service member's off-duty job, a California rental property or a business here is taxable. In that case you file Form 540NR with Schedule CA (540NR) and report only the California-source part.

2. California residents: military pay is taxable

California has no general exemption for active duty pay. Pub 1032 says service members domiciled in California must include military pay in total income, and it counts as California-source income while stationed in California. If you are a Californian stationed in San Diego, expect to pay California tax on your military pay.

The flip side: California service members who leave the state on PCS orders become nonresidents for income tax purposes, and military pay earned while permanently stationed elsewhere is not California-source income. Only California-source income stays taxable.

3. Military spouses

The Military Spouses Residency Relief Act (MSRRA) and the Veterans Auto and Education Improvement Act of 2022 give spouses a choice. Per Pub 1032, a service member and spouse can elect to use the service member's residence, the spouse's residence, or the service member's permanent duty station for state tax purposes. A spouse who is domiciled outside California and is here to be with the service member does not owe California tax on wages earned here.

4. Combat pay and deployments

Pub 1032 treats combat pay as nontaxable and lets you elect to count it as earned income for California's earned income tax credit if that raises your credit. One gap: California did not adopt the federal extension of the combat-zone exclusion to Egypt's Sinai Peninsula. If you served in a designated combat zone, California gives up to 180 days to file and pay without interest or penalties.

5. The new retirement exclusion

Starting with tax year 2025 and running through 2029, California lets qualifying taxpayers exclude up to $20,000 of uniformed services retirement pay, and separately up to $20,000 of Survivor Benefit Plan annuity payments. The cutoff is federal adjusted gross income (AGI) of $125,000, or $250,000 for joint filers and surviving spouses. It was enacted in budget trailer bill SB 132, signed June 27, 2025, and lives in Revenue and Taxation Code sections 17132.9 and 17132.10. The Legislative Analyst's Office estimated it would help about 130,000 veterans.

6. Sales tax on cars

Being a nonresident does not get you out of sales tax on a car bought here. CDTFA exempts a vehicle from use tax only if you bought it and took delivery outside California before you received orders to come here. San Diego County rates run from 7.75% to 8.75% depending on the city (CDTFA, operative October 1, 2026). Registration, smog and the REG 5045 fee waiver are covered in the PCS to San Diego checklist.

7. Property tax for disabled veterans

Veterans rated 100% service-connected, or paid at 100% for unemployability, can take this exemption off their home's assessed value; some unmarried surviving spouses qualify too. The basic exemption is filed once with the San Diego County Assessor on form BOE-261-G. The low-income version must be filed every year by February 15, and late claims get 85% of the exemption. For 2026 the figures were $180,671 and $271,009. See How a VA loan works in San Diego and San Diego property tax rates and due dates.
