San Antonio Property Taxes 2026: Rates, Exemptions & the Bill

What do relocation buyers actually pay in San Antonio property taxes in 2026?

What Do San Antonio Property Taxes Cost in 2026, in Real Dollars?

San Antonio's headline rates look small until you multiply them across every line item. For the 2026 tax year, a home inside San Antonio city limits is taxed by at least six units. Here are the 2026 adopted rates that are already locked in:

| Taxing unit | 2026 rate (per $100) | Status | |---|---|---| | City of San Antonio | $0.56288 | Adopted Sept. 17, 2026 — up from $0.54159 (first city increase in 30+ years) | | Bexar County (total incl. road & flood) | $0.299999 | Held at 2025 rate | | University Health (hospital district) | $0.276235 | Held at 2025 rate | | Alamo Colleges District | $0.166650 | Adopted for 2026 | | San Antonio River Authority | $0.019300 | Adopted for FY 2027 | | Your school district | ~$1.00–$1.20 | Varies by ISD; several face Nov. 3, 2026 votes |

Add the five non-school lines and you get $1.325064 per $100 before the school district enters the picture. The school district is the biggest single line item — typically close to half of the total bill.

So what does that mean on an actual price? Take a $300,000 home with a homestead exemption on file (the case for most owner-occupants). The $140,000 school exemption drops school-taxable value to $160,000. Using a typical ~$1.1552 school rate:

• School portion: $160,000 ÷ 100 × $1.1552 = $1,848/yr
• City, county, hospital, college, river authority: $300,000 ÷ 100 × $1.325064 = $3,975/yr
• Total: ≈ $5,824/yr — about $485/month added to your mortgage through escrow.

Scale it up: on a $400,000 homesteaded home the same math lands around $8,300/yr, or about $692/month in tax escrow. That monthly figure surprises relocation buyers more than anything else in the buying process — it can be larger than the principal-and-interest difference between two price tiers.

One more practical point: Texas has no state income tax, which is the entire reason these rates run 30–60% above the national norm. You're trading income tax for property tax. For high earners that trade still wins; for buyers stretching on a single income, the property tax line deserves as much spreadsheet time as the interest rate.

What Changed in 2026 That Moved the Numbers?

Three things, pulling in different directions.

The city raised its rate for the first time in over three decades. San Antonio City Council adopted $0.56288 per $100 in September 2026, a 3.9% increase that the city's own notice estimates adds roughly $35 to $49 a year to the average homestead's city tax bill. Small in dollars, significant as a precedent — and local reporting notes the two-year budget plan already assumes another increase next year.

The state dramatically expanded the homestead exemption. Texas voters approved Proposition 13 in November 2025, lifting the school-district homestead exemption from $100,000 to $140,000, effective January 1, 2026. A companion measure (Proposition 11) raised the additional exemption for homeowners 65 or older and those with disabilities from $10,000 to $60,000 — a combined $200,000 of school-taxable value shielded for seniors. For most homeowners, the bigger exemption offsets the city's rate increase and then some — but only on the school-district portion, and only if the exemption is actually on file.

The school-district piece is still in motion. Several San Antonio-area districts have tax and bond measures on the November 3, 2026 ballot. San Antonio ISD is asking voters for a 3.17-cent M&O rate increase (Proposition A) plus a $600 million bond package (Propositions B–D); the district estimates all four passing would add about $1.99/month to the average homeowner's school bill in the 2026–27 school year, rising to roughly $3.25/month in 2027–28. Northside ISD has a 3-cent request plus $886.2 million in bonds, and Schertz-Cibolo-Universal City ISD is asking for 12 cents after voters rejected a smaller request last year. If you're buying in one of these districts, the bill you see on this year's tax records may not be the bill you pay next year.

How Does the $140,000 Homestead Exemption Actually Work?

This is where relocation buyers leave money on the table most often, so the mechanics matter.

The homestead exemption removes $140,000 from the value your school district can tax. It does not touch the city, county, hospital, college, or river authority lines — those are calculated on full appraised value. At a ~$1.1552 school rate, the exemption saves roughly $1,610 a year on a qualifying home. It stacks with a second layer of protection: Texas caps annual appraised value growth at 10% per year for homesteaded properties, so a hot neighborhood can't double your taxable value in one year.

Two catches. First, nothing is automatic. The exemption applies only if you filed it with the Bexar County Appraisal District — your title company and your lender do not file it for you. New arrivals assume the paperwork from closing handled it; it didn't. File right after you close, and confirm it shows on your account on BCAD's website. Second, the exemption travels with you, not with the house: if the sellers had a homestead exemption, it ends when they move out, and the home reverts to full taxable value until your own filing takes effect.

There are additional exemptions worth knowing. Homeowners 65+ and disabled homeowners get the extra $60,000 school exemption plus a tax ceiling that freezes the school-district portion of the bill at the year they first qualified. Disabled veterans receive exemptions tied to their VA disability rating under Texas law, with a 100% rating carrying a total property-tax exemption. If any of these apply in your household, they're worth more than the standard homestead — verify with BCAD before your first tax year.

Where Do Property Tax Bills Vary Most Around San Antonio?

New buyers tend to assume the tax rate is a San Antonio number. It isn't — it's an address number, and it can swing thousands of dollars within a 15-minute drive.

School district is the dominant variable. Rates and exemptions differ across SAISD, Northside, North East, Judson, Comal, and Schertz-Cibolo-Universal City ISDs, and each sets its own 2026 rate. A $350,000 home in one district can carry a materially different school line than the same-priced home across the district boundary. Always pull the actual current-year tax bill for a specific address — not the city's average — before you make an offer.

City limits vs. unincorporated county. Homes outside San Antonio city limits skip the $0.56288 city line entirely, saving roughly $1,700 a year on a $300,000 home. That's real money, but check what replaces it: some addresses in the city's extraterritorial jurisdiction or in municipal utility districts (MUDs) carry special-district rates that can meet or exceed what the city line would have been. New construction on the far edges of Bexar County is the most common place this surprise shows up.

The appraisal itself. The Bexar County Appraisal District sets your home's market value each January 1, and Texas adopted AI-assisted mass appraisal models statewide in 2026. These systems can push values faster in appreciating neighborhoods — and they can also get things wrong on individual homes. Independent estimates put 30–60% of Texas properties as over-assessed in any given year. When you buy, the purchase price gives you fresh comparable data; use it.

How Do San Antonio Taxes Compare to the States You're Leaving?

For context, Texas ranks seventh nationally for property-tax burden — WalletHub's 2026 study put the median Texas bill at $4,232 on a $283,800 median home value, and the Tax Foundation pegs the state's effective rate around 1.36%, against a national average near 0.9–1.1%.

If you're coming from California, the trade looks like this: California's Prop 13 holds the base rate near 1% plus local bonds (an effective rate near 0.7% in practice), but California's top income tax rate reaches 13.3%. Texas charges you no income tax at all and makes it up on property. The math favors Texas for higher earners and tightens for buyers whose income is modest relative to their home price — a $500,000 home here carries roughly $9,700–$11,000 a year in property taxes, which is the number people underestimate when they move from a low-property-tax state.

For military families on VA loans — a big share of San Antonio relocation buyers — the property tax line hits differently than it does for conventional buyers. Zero down and no PMI stretch BAH impressively far on price, but escrow doesn't care about your down payment: a $600/month tax line consumes a fixed chunk of your housing allowance whether you put 0% or 20% down. Price your search on the total monthly payment, taxes included, not on the loan amount. Veterans with a service-connected disability rating should also check their exemption status before closing — it can change the payment math materially. If you're mapping a PCS to the area, start with the military relocation overview to line up neighborhoods with your BAH and commute.

What Can You Do to Lower the Bill After You Buy?

Once you own the home, four levers are in your control:

1. File the homestead exemption immediately. This is the highest-dollar action per minute of effort in Texas homeownership. Then verify it actually appears on your BCAD account — the relief only reaches your bill if the exemption is on file.
2. Protest the appraisal every year. You can protest through BCAD's online process or hire a protest firm (many work on contingency, taking a percentage of first-year savings). The protest targets the assessed-value half of your bill — the only piece a homeowner can directly fight. Even a $20,000 reduction at San Antonio's combined rates saves $400+ a year, every year, because the lower base compounds.
3. Claim every exemption you qualify for. Over-65, disabled, disabled veteran, and surviving-spouse exemptions stack beyond the standard homestead. If your household situation changes, re-file.
4. Watch your district's rate votes. City, county, and school boards set rates every summer and fall, and bonds on the November ballot become debt-service lines on your future bills. San Antonio-area voters are deciding several of these on November 3, 2026 — the outcome shows up in the 2027 tax year.

For buyers still shopping, the pre-purchase version of this is simpler: compare actual tax bills address by address. Two homes at the same price in different districts or inside vs. outside city limits can differ by $2,000+ a year, which is $167+ a month on the payment — enough to change which home you can afford. Our moving-to-San-Antonio guide covers the neighborhoods where those trade-offs play out most.

In Closing

San Antonio property taxes in 2026 are a study in offsetting forces: the city's first rate increase in a generation nudged bills up, while the $140,000 homestead exemption pulled the school portion down — and the November 3 school votes will write the next chapter. The practical takeaway is that your bill is an address-specific number, not a city average, so run the actual math on every home you're serious about before you write an offer.

Your one next step: pull the last two years of tax bills for any home you're considering and compare them against what a homestead exemption would do to the school line.
