San Diego is home to the largest concentration of military personnel in the United States — MCAS Miramar, Naval Base San Diego, Camp Pendleton, and dozens of other installations make this one of the most military-connected cities in the country. Active duty service members, veterans, military spouses, and retirees face a tax situation that's genuinely different from civilian filers, and finding a CPA who understands military-specific rules can make a significant financial difference.
Military Tax Rules Most General CPAs Get Wrong
Basic Allowance for Housing (BAH) and Basic Allowance for Subsistence (BAS)
BAH and BAS are not taxable income — they're excluded from gross income entirely. But they're not zero dollars either: they affect your eligibility for certain credits (like the Earned Income Credit, which uses earned income thresholds). A CPA who doesn't work with military clients may not know how to correctly treat these allowances, which can result in errors on means-tested credits.
Combat Zone Tax Exclusion
Service members serving in designated combat zones can exclude all military pay from federal income tax for any month they serve in the zone — even if it's just one day of the month. Commissioned officers are subject to a cap (the highest enlisted pay plus hostile fire/imminent danger pay), but enlisted personnel and warrant officers exclude everything. The exclusion also extends the deadline for filing tax returns and paying taxes. Many CPAs who don't work with military clients have never filed a return with a combat zone exclusion.
State income tax and domicile
This is where military tax gets genuinely complex. Under the Servicemembers Civil Relief Act (SCRA), active duty service members maintain their legal domicile (home state) regardless of where they're stationed. A California-stationed service member who is domiciled in Texas owes no California income tax on military pay — but may owe Texas nothing (no income tax) and owes federal tax normally.
The Military Spouses Residency Relief Act (MSRRA) extends similar protection to military spouses who move with their service member: they can claim the same domicile as the military member, potentially avoiding California income tax on their own wages. San Diego CPAs who work with military families know how to set this up correctly.
Thrift Savings Plan (TSP)
The TSP is the military's 401(k) equivalent, offering both traditional (pre-tax) and Roth options. Contributions made from combat zone excluded pay go into the Roth TSP tax-free and come out tax-free — one of the most valuable tax arbitrage opportunities available to any investor. A military-focused CPA will recommend maximizing this during combat zone deployment.
Veterans: VA Disability and Tax
VA disability compensation is not taxable — it's excluded from federal and state income tax entirely. But it interacts with other benefits in ways that create planning opportunities:
- Military retirement pay — Unlike VA disability, military retirement pay IS taxable. But veterans who receive both retirement pay and disability pay may be eligible for the Concurrent Retirement and Disability Pay (CRDP) program, which restores retirement pay that was previously offset by disability pay. The tax treatment of CRDP vs. disability pay needs to be handled carefully.
- Combat-Related Special Compensation (CRSC) — Tax-free compensation for combat-related disabilities, separate from VA disability. The interaction with retirement pay and taxes requires specialist knowledge.
- Survivor Benefit Plan (SBP) — Premiums are deductible; payments to survivors are partially taxable. A CPA who has worked with military retirees will know how to handle this.
California-Specific Issues for San Diego Military
California taxes military retirement pay (unlike some states that exempt it). For veterans who retire and stay in California, this is a meaningful tax burden — the full pension is subject to California's up to 13.3% rate. Some veterans choose to establish domicile in a no-income-tax state (like Nevada or Texas) before retirement specifically to avoid California tax on their pension.
California does, however, provide a property tax exemption for disabled veterans. The exemption amount depends on disability rating and income. A San Diego CPA with military clients will know the current thresholds and application process.
What to Look for in a San Diego Military CPA
- Specific mention of military clients in their specialties
- Knowledge of SCRA domicile rules and MSRRA for spouses
- Experience with combat zone exclusions on prior returns
- Familiarity with CRDP, CRSC, and SBP for military retirees
- California domicile planning for pre-retirement veterans
Free Resources for Military Tax Filers
It's worth noting that the IRS offers free tax preparation for military through the VITA (Volunteer Income Tax Assistance) program at most installations. MilTax, offered through the Department of Defense, is another free resource. These are appropriate for straightforward military returns. But for complex situations — multi-state domicile issues, large investment accounts, rental properties, or military retirement planning — a CPA who specializes in military clients delivers value that free programs can't match.
