How to Appeal Your Property Tax Bill in Bexar County, TX
Texas homeowners have the right to protest their property tax appraisal every single year — and in Bexar County, the case for doing so is strong. With effective property tax rates running **1.85–2.1%** depending on your school district, even a modest reduction in appraised value translates to meaningful annual savings.
The Bexar County Appraisal District (BCAD) determines the appraised value of every property in the county. As San Antonio home values have risen — driven partly by Austin spillover and strong military and healthcare employment — BCAD appraisals have followed, often aggressively.
For retirees on fixed incomes, these rising appraisals create a compounding burden. A $350,000 home at a 2.0% effective rate generates a **$7,000 annual property tax bill**. A successful protest that reduces the appraised value by just 10% saves $700/year — every year until the next increase.
The BCAD Protest Process
The Bexar County property tax protest process is structured and accessible to individual homeowners:
**Step 1: File your protest by the deadline**
The protest deadline is typically **May 15** (or 30 days after your appraisal notice, whichever is later). You can file online through the BCAD website, by mail, or in person. Filing is free.
- Recent comparable sales (comps) within a half-mile of your property showing lower values
- Photos of property condition issues (deferred maintenance, foundation problems, roof age)
- An independent appraisal if you have one
- Documentation of any damage or needed repairs
**Step 3: Informal hearing**
BCAD offers informal hearings where you meet with an appraiser to discuss your case. According to Texas Comptroller data, the majority of successful protests are resolved at this stage. Be prepared, be professional, and bring your evidence.
**Step 4: Formal hearing (Appraisal Review Board)**
If the informal hearing doesn't resolve your protest, you can proceed to the Appraisal Review Board (ARB). This is a formal panel that reviews your evidence and the district's evidence. You can also hire a property tax agent to represent you — many work on a contingency basis (they only charge if they save you money).
Over-65 Benefits Many Retirees Miss
Texas offers several property tax benefits specifically for homeowners age 65 and older that are critically important in the San Antonio market:
Over-65 School Tax Ceiling
Once you turn 65 and apply for the over-65 homestead exemption, your **school district taxes are frozen** at the amount you paid in the year you qualified. This is not a one-time benefit — it's a permanent ceiling that prevents school tax increases for as long as you own the home. Given that school taxes typically represent 50–60% of a Texas property tax bill, this is an enormous benefit.
Over-65 Exemption
In addition to the standard homestead exemption ($100,000 off school district value), over-65 homeowners receive an additional **$10,000 exemption** from school district taxes. Many taxing entities (city, county, hospital district) offer their own additional exemptions.
Disability Exemptions
Homeowners with disabilities qualify for similar benefits regardless of age. If you're a disabled veteran, Texas offers additional exemptions that can be substantial.
Transferring Your Benefits
If you sell your home and buy another in Texas, you can **transfer your school tax ceiling** to your new home, adjusted proportionally. This portability benefit is poorly understood — many retirees who move within San Antonio or to nearby New Braunfels lose their tax ceiling simply because they don't file the transfer paperwork.
Common Protest Mistakes to Avoid
- **Missing the deadline**: If you miss May 15 (or your specific 30-day window), you lose your right to protest for that year. Set a calendar reminder.
- **Protesting without evidence**: Simply saying "my taxes are too high" is not effective. Bring comparable sales data, photos, or other documentation.
- **Ignoring the informal hearing**: The informal hearing is your best opportunity for a negotiated reduction. Skipping it and going straight to the ARB removes a valuable step.
- **Forgetting to apply for exemptions**: The homestead exemption and over-65 exemptions are not automatic — you must apply. If you haven't applied, do so immediately. Back-filing may be possible for up to two years.
Local Market Context
Bexar County property values have been rising steadily, with some neighborhoods seeing 15–25% increases in appraised values over the past three years. BCAD has been particularly aggressive in reassessing properties in the Stone Oak, Alamo Ranch, and Boerne corridor areas where new construction provides comparables that pull up existing home values.
The Texas Comptroller's Property Tax Assistance Division reports that statewide, approximately 50% of homeowners who protest receive a reduction. In Bexar County, the rate is comparable, making the time investment well worth the effort.
Frequently Asked Questions
How much does it cost to protest my property taxes in Bexar County?
Filing a protest is free. If you hire a property tax agent, most work on a contingency basis — typically charging 30–40% of the first year's savings. If they don't reduce your bill, you pay nothing.
Can I protest every year?
Yes. Texas law allows homeowners to protest their property tax appraisal every year. There is no limit on how many consecutive years you can file.
What if I just bought my home — can I still protest?
Absolutely. Your purchase price is one data point, but BCAD may have appraised your property above what you paid. If your appraised value exceeds your purchase price, you have a strong case for reduction.
How long does the protest process take?
The informal hearing is typically scheduled within 30–60 days of filing. If you proceed to the ARB, the formal hearing may take an additional 30–60 days. Most protests are fully resolved within 3–4 months of filing.
