Texas homeowners pay some of the highest property taxes in the United States. With no state income tax, local governments lean heavily on property assessments to fund schools, roads, and hospitals — and that means your home's appraised value is the single biggest number standing between you and your annual tax bill.
The good news: Texas law gives every homeowner the right to protest that number. And not in a symbolic way. The protest process is written into the Texas Tax Code, every county appraisal district is legally required to hear your case, and roughly one in three homeowners who file actually win a reduction.
This is the complete statewide guide — the process that applies to all 254 Texas counties, the things that differ by county, and what to do before the May 15 deadline.
The Universal Texas Protest Process
No matter where you live in Texas — Houston, Dallas, San Antonio, Austin, El Paso, or a small town in the Hill Country — the right to protest your property tax assessment comes from the same place: Texas Tax Code Section 41.44(a)(1).
That statute says you must file a written notice of protest with your County Appraisal Review Board (ARB) by May 15, or 30 days after the appraisal district mails your Notice of Appraised Value — whichever is later.
Your grounds for protest are broad. The most common, and usually the most successful, is that your property's market value was assessed too high compared to similar homes that recently sold in your area. You can also protest unequal appraisal (your home is assessed higher than comparable properties), denied exemptions, or incorrect property records (wrong square footage, wrong number of bathrooms, unfinished basement counted as finished).
How It Works in Every Texas County
The steps are the same statewide, even though each county's appraisal district has its own name and portal:
- Receive your Notice of Appraised Value — mailed in April or early May.
- File your Notice of Protest — online, by mail, or in person by the deadline.
- Informal hearing with an appraiser — a short meeting (often by phone or video) where you present your evidence and the appraiser can agree to a reduction on the spot. Roughly half of all protests settle here.
- Formal ARB hearing — if you don't settle informally, a three-member Appraisal Review Board panel hears your case. You present evidence, the district presents theirs, and the board issues a written decision, usually within a few weeks.
- Binding arbitration or district court appeal — if you disagree with the ARB, you can escalate, but most homeowners stop at the ARB level.
The entire process is free. There is no filing fee. You do not need a lawyer.
Key Deadlines Statewide
- May 15 — the default protest deadline for most Texas homeowners.
- 30 days after your notice — if your Notice of Appraised Value arrives after mid-April, you get 30 days from the mail date instead.
- Keep the envelope. The postmark is your proof of timely filing if anything is ever disputed.
Miss the deadline and you lose your right to protest that year's value entirely. There are no exceptions for being out of town, being sick, or not opening your mail. This is the single most important date on a Texas homeowner's calendar.
Filing Methods
Almost every Texas county now offers three ways to file:
- Online — the fastest and most reliable. Every major metro county has a dedicated portal (more on these below).
- Mail — send your signed Notice of Protest (Form 50-132) to your appraisal district. Certified mail with return receipt is strongly recommended.
- In person — walk-in filing is still available at every district office, though lines get long in the first two weeks of May.
The Major Texas Counties — What's Different
Every county follows the same state law, but the portal, the culture, and the evidence standards vary. Here's a quick tour of the five biggest metros.
Harris County (HCAD)
Home to Houston and roughly 1.7 million parcels, Harris Central Appraisal District runs the iFile online portal at hcad.org. Hearings are efficient, the district is used to high volume, and informal settlements are common. Learn more on our Harris County property tax appeal guide or read the complete 2026 Harris County appeal walkthrough.
Dallas County (DCAD)
Dallas Central Appraisal District uses the uFile online system. Dallas has some of the most aggressive year-over-year value increases in the state, which means protesting is often more valuable here than anywhere else. Comparable sales evidence works particularly well. Full details on the Dallas County appeal page.
Tarrant County (TAD)
Tarrant Appraisal District covers Fort Worth and Arlington. TAD had a rocky 2024 with a cyber incident and leadership turnover, which created longer wait times and some inconsistent hearings — but homeowners who file patient, well-documented protests still win at normal rates. See our Tarrant County guide.
Bexar County (BCAD)
Bexar Appraisal District serves San Antonio. BCAD is known for a homeowner-friendly informal process — many protests settle in a single phone call with an appraiser. Evidence standards are reasonable, and unequal-appraisal arguments work well here. More on the Bexar County appeal page.
Travis County (TCAD)
Travis Central Appraisal District serves Austin and uses the E-File portal. Austin's volatile market — years of rapid appreciation followed by cooling — means TCAD assessments often lag the real market, in both directions. Timing and recent-sale comps matter more here than almost anywhere else in Texas. See the Travis County guide.
Texas-Wide Exemptions
Before you even think about the protest itself, make sure every exemption you qualify for is already applied to your property. An unprotested bill with missing exemptions is money left on the table.
- Homestead exemption — up to $100,000 off your school-district appraised value for your primary residence. Every Texas homeowner should have this.
- Over-65 exemption — an additional $10,000 school-district exemption plus a school tax ceiling (your school taxes freeze at the level of the year you turn 65 or qualify).
- Disability exemption — same $10,000 school exemption and tax ceiling as over-65. You can't stack both, but you can choose whichever is better for you.
- Disabled Veteran exemption — ranges from $5,000 to a full 100% property tax exemption depending on your VA disability rating.

Evidence That Works
Across all 254 Texas counties, the single most persuasive piece of evidence in a protest is the same thing: recent comparable sales.
A "comp" is a home similar to yours — same neighborhood, similar square footage, similar age, similar condition — that sold recently. If three or four comparable homes sold for less than your appraised value, the appraisal district has a very hard time defending that value.
What else helps:
- Photos of condition issues — foundation cracks, roof damage, outdated kitchens, deferred maintenance.
- Contractor repair estimates — a quote for $25,000 in foundation repair is powerful evidence of diminished value.
- Unequal appraisal data — homes on your street assessed for less than yours.
- Your closing statement — if you bought recently below the appraised value, that is the single strongest comp possible.

When to Use a Service vs File Yourself
Filing yourself is genuinely doable. The forms are short, the portals are usable, and informal hearings are conversational. If you have time, attention, and confidence with documents, you can absolutely do this alone and keep 100% of the savings.
A service makes sense when:
- You don't have time to pull comparable sales and build an evidence package.
- Your assessment is complex (high-value home, unusual property, multiple parcels).
- You've tried before and lost, and want a professional second look.
- You qualify for exemptions you haven't claimed yet, and want someone to sort the whole picture at once.
Most reputable services, including ClaimEngine, work on contingency — you pay nothing unless your assessment is actually reduced.
Conclusion
Property taxes in Texas are high, but they are not fixed. Every year, the appraisal district hands you a number, and every year, you have the legal right to challenge it. The process is free, the deadline is clear, and the evidence that wins cases is usually already available in public records.
Whether you live in Harris, Dallas, Tarrant, Bexar, Travis, or any of the other 249 Texas counties, the playbook is the same: check your exemptions, gather your comps, file before May 15, and show up — either in person, by phone, or through a service that does it for you.
