Texas Property Tax Guide for San Antonio Homeowners

Texas is one of the few states with no personal state income tax — and homeowners here pay for that benefit through some of the highest property tax rates in the country. If you own a home in San Antonio or are thinking about buying one, understanding how Texas property taxes work is not optional. It is essential to planning your budget, protecting your investment, and potentially saving hundreds or even thousands of dollars each year.

As a dual-licensed real estate agent and Mortgage Loan Officer (Texas License #794969, NMLS #2792614), I walk clients through the full financial picture of homeownership — and property taxes are a big part of that conversation. Here is everything San Antonio homeowners need to know about how Texas property taxes work, what exemptions are available, and how to protest your appraisal if you believe it is too high.

Why Are Texas Property Taxes So High?

Texas has no state income tax. Instead, the state relies heavily on local property taxes to fund public services — primarily public schools, but also county government, city services, emergency services, and special districts. Because there is no income tax to supplement these costs, local property tax rates tend to be higher than the national average.

The statewide average effective property tax rate in Texas hovers around 1.47%, but that number varies widely depending on where you live. In the San Antonio metro, total effective tax rates typically range from 2.0% to over 2.5% of your home's appraised value — depending on which taxing jurisdictions overlap your property.

That means if your home is appraised at $300,000 and your total tax rate is 2.2%, your annual property tax bill would be roughly $6,600 — or about $550 per month added to your housing costs.

Who Sets the Tax Rates?

Texas property taxes are set locally, not by the state. Multiple taxing entities layer their rates on top of each other based on where your property is located. For a typical San Antonio homeowner, the major taxing entities include:

• Your school district — the largest portion of your tax bill, typically $0.96 to $1.26 per $100 of taxable value depending on the district (e.g., NEISD, NISD, Alamo Heights ISD, Harlandale ISD).
• City of San Antonio — currently $0.54159 per $100 of taxable value.
• Bexar County — currently $0.299999 per $100 of taxable value.
• Additional districts — Depending on your location, you may also owe taxes to entities like VIA Metropolitan Transit, the Alamo College District, and various utility or emergency service districts.

Six county-wide entities alone charge a combined base rate of approximately $1.285 to $1.29 per $100. When you add your school district and any special jurisdictions, the total can easily exceed $2.00 per $100.

How Bexar County Appraises Your Property

Every year, the Bexar County Appraisal District (BCAD) determines the market value of every property in the county. This appraised value — not your purchase price — is what your tax rate is applied to.

Here is how the timeline works:

• January – April: BCAD appraisers evaluate properties using sales data, market trends, and property characteristics.
• April – May: BCAD mails Notices of Appraised Value to property owners. This notice tells you what BCAD believes your property is worth for the upcoming tax year.
• May 15: This is the deadline to file a protest if you disagree with your appraised value. You must file by May 15 or within 30 days of receiving your notice, whichever is later.
• June – July: Informal conferences and formal hearings take place before the Appraisal Review Board (ARB).
• Fall: Tax bills are sent out, typically due by January 31 of the following year.

BCAD uses mass appraisal techniques, meaning they evaluate thousands of properties using computer models. That process is not perfect — and it is one reason why protesting your appraisal can be so effective.

The Homestead Exemption: Your Most Important Tax Break

If the property is your primary residence, you qualify for a Texas homestead exemption. This is the single most valuable property tax benefit available to homeowners, and it works in two ways:

• Exemption amount: The school district homestead exemption is $140,000 off your appraised value for school tax purposes. Additional exemptions from the City of San Antonio and Bexar County may apply depending on your location.
• Homestead cap (10% limit): Once you have a homestead exemption in place, your appraised value for tax purposes can only increase by a maximum of 10% per year — even if your home's market value jumps by more than that. This protects you from sudden spikes in your tax bill during hot markets.

Important: You must file for the homestead exemption with the Bexar County Appraisal District. The exemption is not automatic — you have to apply. If you recently purchased a home and have not filed, you may be leaving significant money on the table.

On a $300,000 appraised home with a $140,000 school homestead exemption, your taxable value for school taxes drops to $160,000. At a school tax rate of $1.10 per $100, that saves you roughly $1,540 per year compared to a homeowner without the exemption.

The Over-65 Exemption: Extra Savings for Seniors

If you are 65 or older (or if you are the surviving spouse of someone who was 65 at the time of death), you qualify for an additional exemption on top of the standard homestead exemption:

• Additional $60,000 exemption on school district taxes — on top of the $140,000 homestead exemption, meaning your school-taxable value is reduced by a total of $200,000.
• Tax ceiling (freeze) on school taxes: Once you qualify for the over-65 exemption, your school tax bill is frozen at the amount you paid in the year you turned 65. Your school taxes cannot go up — even if your home's appraised value increases — as long as you continue to occupy the home as your primary residence.
• Optional local exemptions: Some cities, counties, and special districts also offer additional over-65 exemptions or tax freezes. Check with BCAD for what applies in your area.

The school tax freeze is especially powerful for long-term homeowners. If you turned 65 when your school tax bill was $1,800 per year, that amount stays locked in — even as your home's value appreciates over time. This can represent tens of thousands of dollars in savings over the life of your ownership.

How to Protest Your Property Tax Appraisal

Every property owner in Texas has the right to protest their appraised value if they believe it is inaccurate or unfair. In Bexar County, tens of thousands of protests are filed each year — and many result in reduced appraised values. Here is how the process works:

Step 1: File Your Protest

You must file a Notice of Protest by May 15 or within 30 days of receiving your Notice of Appraised Value (whichever is later). Filing is free and can be done:

• Online: Through the BCAD website at bcad.org using your Owner ID and PIN.
• By mail or in person at the Bexar County Appraisal District office.

Step 2: Prepare Your Evidence

The key to a successful protest is market-based evidence, not complaints about your tax bill. BCAD cares about whether your appraised value accurately reflects your property's market value. Strong evidence includes:

• Comparable sales: Gather 3 to 5 recent sales of similar homes in your area that sold for less than your appraised value. Adjust for differences in square footage, lot size, condition, and upgrades.
• Unequal appraisal data: If similar homes on your street or in your neighborhood are appraised at a lower value per square foot, that is powerful evidence of an unfair appraisal.
• Photos of condition issues: Document any deferred maintenance, structural concerns, outdated systems, or other condition factors that BCAD's model may not have accounted for.
• Professional repair estimates: If a contractor has provided an estimate for needed repairs, include that as supporting evidence.

Submit your evidence early — ideally within 7 days of receiving your protest confirmation — to give BCAD staff time to review it before your meeting.

Step 3: Informal Conference

Most protests begin with an informal conference with a BCAD appraiser. This is a relatively relaxed meeting where you present your evidence and the appraiser reviews it. A large percentage of protests are resolved at this stage — often with a value reduction that both sides agree on.

Step 4: Formal Hearing (If Needed)

If you and the BCAD appraiser cannot agree during the informal conference, your case moves to a formal hearing before the Appraisal Review Board (ARB) — an independent panel of citizens. You will present your evidence, and BCAD will present theirs. The ARB issues a binding decision.

Tips for a Successful Protest

• Protest every year. Even if you succeeded last year, values change. Make it an annual habit.
• Focus on value, not taxes. The hearing is about whether your appraised value is accurate — not about whether your tax rate is fair.
• Use the comps. Nothing speaks louder than recent sales data showing your home is overvalued.
• Be specific. Point out exact differences between your home and the comparable properties — deferred maintenance, smaller lot, fewer upgrades.
• Consider a professional. If you are not comfortable handling the protest yourself, property tax consultants and attorneys specialize in this process and often work on a contingency basis.

Other Property Tax Exemptions in Texas

Beyond the homestead and over-65 exemptions, Texas offers several additional exemptions that may apply to you:

• Disabled veteran exemption: Veterans with service-connected disabilities of 10% or more qualify for a partial exemption, and those rated 100% disabled may qualify for a full exemption.
• Disabled homestead exemption: Homeowners who are receiving Social Security Disability benefits may qualify for an additional exemption.
• Agricultural or timber valuation (1-d-1): If your land qualifies for agricultural or timber use, it can be taxed on its productive value rather than its market value — a significant reduction for qualifying rural properties.

How Property Taxes Affect Your Monthly Payment

One of the most common questions I get from buyers is: "What will my actual monthly payment be?" Property taxes are a critical part of that answer.

When you have a mortgage, your lender typically collects property taxes monthly as part of your escrow payment. That means your total monthly housing payment (often called PITI — Principal, Interest, Taxes, and Insurance) is higher than just the mortgage alone.

These are gross estimates before exemptions. With a homestead exemption, your actual tax bill will be lower — but it is important to understand the full picture before you buy.

How Property Taxes Affect What You Can Afford

When you are getting pre-approved for a mortgage, your lender calculates your debt-to-income (DTI) ratio — and property taxes are included in that calculation. A home with a higher tax rate means a higher monthly payment, which can affect how much you qualify to borrow.

This is one of the reasons I encourage buyers to look at the total cost of ownership, not just the sticker price. A $280,000 home in a lower-tax area may actually cost you less per month than a $260,000 home in a higher-tax district.

As your dual-licensed agent and MLO, I factor property taxes into your affordability analysis from day one — so there are no surprises when you see your monthly payment estimate.

Key Dates to Remember

• January 1: Effective date of appraisals for the new tax year.
• April – May: Notices of Appraised Value are mailed by BCAD.
• May 15: Deadline to file a property tax protest.
• October: Tax bills are typically sent out by the county.
• January 31 (of the following year): Property tax payments are due. After this date, penalties and interest begin accruing.
