Moving from California to San Antonio: The Tax & Cost Reality

California has the highest state income tax in the country. Texas has none. California's Prop 13 locks property taxes near 1.1% for long-term owners — Texas runs 1.8–2.3%. The net result for California retirees is almost always favorable for Texas, but the math is more interesting than most guides let on.

The Core Finding

California taxes retirement income (IRA distributions, 401(k) withdrawals, pension income) at rates up to 13.3%. Texas taxes none of it. For most California retirees, the income tax savings from moving to San Antonio significantly outweigh the property tax increase — but only after accounting for what they'll actually owe on a Texas home vs. their California property tax under Prop 13.

California Income Tax on Retirement Income

California does not exempt retirement income the way Illinois does. Social Security is partially exempt from California income tax (California follows federal SS taxation rules), but:

  • Traditional IRA and 401(k) distributions: Taxed as ordinary income at California's marginal rates
  • Pension income: Taxed as ordinary income (with partial exclusions for some public employee pensions)
  • Roth IRA distributions: Tax-free (same as federal)
  • Investment income: Capital gains taxed as ordinary income (unlike federal, no favorable long-term rate)

California's income tax rates for retirees drawing $50,000–$100,000 in retirement distributions:

  • $50,000 in retirement income: effective California rate approximately 4–6%
  • $80,000: effective rate approximately 6–8%
  • $100,000: effective rate approximately 7–9%

At $80,000 in retirement income, a California retiree is paying approximately $5,000–$6,400/year in state income tax. Moving to Texas eliminates this entirely.

The Prop 13 Property Tax Reality

California's Proposition 13 (1978) caps annual property tax assessment increases at 2% per year for existing owners. Properties are reassessed only upon sale (with some exceptions). The result: California homeowners who have lived in their home for 10–20+ years pay dramatically below-market property tax relative to current value.

A California home purchased in 2005 for $400,000 and now worth $900,000 might be paying property tax on a $500,000 assessed value (original purchase price + 2% annual increases). At California's roughly 1.1% blended rate, that's $5,500/year in property taxes — not $9,900 (the 1.1% of current market value).

When that California homeowner sells and buys in San Antonio, they lose their Prop 13 protection. Their new Texas property is assessed at full purchase price and taxed at Bexar County rates.

ScenarioCalifornia (Prop 13, Long-Term Owner)San Antonio (65+ Bexar, 2025)
Home purchase value (CA) / current value (TX)$900K current value$500K purchase
Assessed value~$500K (Prop 13 basis)$500K (full purchase)
Property tax rate~1.1% (blended)~1.7% (65+, Bexar 2025)
Annual property tax~$5,500/year~$8,500/year
Annual differenceTexas costs $3,000/year more in property tax

The property tax increase is real — but compare it to what the same retiree saves on income taxes.

The Full Comparison: What Net Does It Cost or Save?

Tax CategoryCaliforniaSan Antonio (Bexar)Annual Difference
State income tax on $80K retirement income~$5,500/year$0SA saves $5,500/year
Property tax (long-term CA owner vs. new TX purchase)~$5,500/year (Prop 13 basis)~$8,500/yearSA costs $3,000/year more
Capital gains tax on investment income ($20K)~$1,600/year (CA taxes at ordinary rate)$0SA saves $1,600/year
Net annual advantage (SA vs. CA)SA saves ~$4,100/year net

In this scenario, a California retiree drawing $80K in retirement income plus $20K in investment income saves approximately $4,100/year net by moving to San Antonio — even after accounting for higher property taxes.

This calculation tilts more strongly in Texas's favor as retirement income increases. At $100K–$150K in retirement distributions, the California income tax bill grows faster than the property tax differential.

Prop 19 Portability: If You're Moving Within California First

California's Proposition 19 (effective 2021) allows homeowners 55+ to transfer their Prop 13 assessed value to a new California home — with certain limitations. This only applies within California. If you're selling your California home and buying in Texas, Prop 19 is irrelevant. You lose your Prop 13 basis at sale regardless.

Some California homeowners are unaware that selling their primary residence — even to retire to Texas — triggers a full reassessment in California if they later return. For multi-home owners or those considering a testing period, consult a California property tax attorney before selling.

The Home Sale Capital Gain

Many California retirees have a large embedded gain in their primary home. The federal exclusion ($250,000 single / $500,000 joint) may shield some of it, but California taxes capital gains above the exclusion as ordinary income — up to 13.3%.

This is not directly related to the Texas move, but it's a significant planning consideration: selling a California home with a $700K embedded gain (above federal exclusion) generates a California state tax bill of $20,000–$30,000 that wouldn't exist if you were already a Texas resident at time of sale.

Planning consideration: Establish Texas residency before closing the sale of your California home if your gain significantly exceeds the federal exclusion. California may attempt to claim tax on the gain if the sale is too close to your domicile change. Work with a CPA experienced in California residency changes.

What Doesn't Transfer: The Lifestyle Reality

The financial case for California-to-San Antonio is real and usually favorable. But California retirees accustomed to ocean proximity, coastal climate, or specific cultural amenities need to calibrate expectations. San Antonio is landlocked. Summer heat is significant (June–September routinely above 95°F). The dining and cultural scene is legitimate but different from major California metros.

San Antonio's 55+ communities offer genuine quality and amenities. Hill Country Retreat at $185/month HOA with resort facilities is a better lifestyle-to-cost ratio than most California retirement options. But it's a different lifestyle, not an equivalent one at lower cost.
