Texas Property Tax Appeals: A Complete Guide for Property Owners

Texas has no state income tax, which sounds great until you see your property tax bill. With effective property tax rates averaging 1.6–2.0% of assessed value — among the highest in the U.S. — property taxes are the primary tax burden for most Texas property owners.

The good news: Texas has a well-established, property-owner-friendly protest system. Every year, hundreds of thousands of Texas property owners successfully appeal their appraisals and reduce their tax bills. If you own property in Texas and have never appealed, you're likely paying more than you should.

How Texas Property Tax Is Calculated

Your property tax bill is determined by three factors:

  1. Appraised value — set by your county's Central Appraisal District (CAD)
  2. Exemptions — homestead, over-65, disabled, agricultural, and others
  3. Tax rates — set by each taxing entity (county, school district, city, MUD, etc.)

The only one you can challenge through the appeals process is the appraised value. Everything else is fixed for a given year.

Critically: Texas appraisal districts are notorious for overvaluing properties. They're dealing with high volume and limited data. Mass appraisal models are blunt instruments. Your CAD-assessed value may be meaningfully higher than what your property would actually sell for.

The Protest Calendar: Deadlines Matter

The Texas protest calendar is rigid:

If you miss the May 15 deadline, your ability to protest for that year is gone. Set a reminder — this is one of the highest-ROI 15-minute tasks you can do for your property finances.

Grounds for Protest

You can protest on two main bases:

1. Value is incorrect (over-market value)
Your property's appraised value exceeds what it would sell for on the open market. This is the most common basis and the easiest to support with comparable sales (comps).

2. Unequal appraisal
Your property is appraised at a higher percentage of market value than comparable properties in your area. Texas law (Section 42.26 of the Tax Code) explicitly requires uniform appraisal — properties must be appraised consistently. Unequal appraisal claims can succeed even when your value appears "market" if neighbors with similar properties are assessed lower.

Both bases can be claimed simultaneously. Many winning protests use unequal appraisal as the primary argument.

The Three-Step Process

Step 1: File Your Protest
File online through your county CAD's portal (most counties now accept this) or mail a written protest (PTAD Form 50-132). State your basis — value or unequal appraisal — and request an informal hearing.

Step 2: Informal Hearing
Before the formal Appraisal Review Board (ARB), most CADs offer an informal settlement process with an appraiser. Bring your evidence — comparable sales, photos of condition issues, your own appraisal if you have one. Many protests settle at this stage with a meaningful reduction.

Step 3: ARB Hearing
If informal doesn't resolve it, you present your case to the ARB — a panel of citizens appointed to hear protests. You present evidence; the CAD appraiser presents theirs. The ARB decides. You have 60 days after an ARB decision to file in district court if you disagree.

What Evidence Wins

Hiring a Property Tax Consultant

Texas has a robust market of property tax consultants and agents who work on contingency — they take a percentage of your first-year tax savings (typically 25–40%) with no upfront fee. If they don't win a reduction, you pay nothing.

For commercial property owners, complex assessments, or anyone who doesn't want to handle the process themselves, this is often the right move. The consultant handles filing, evidence prep, and hearings.

Ownwell specializes in Texas property tax protests for both residential and commercial owners. They handle the entire protest process and only collect a fee if they reduce your bill.

How Much Can You Save?

Results vary by property and county, but data from the Texas Comptroller's office shows that the majority of contested hearings result in some reduction when property owners present evidence. Reductions of 10–20% of assessed value are common; larger reductions occur when significant overassessment is documented.

On a property assessed at $600,000 with a 1.8% effective tax rate, a 15% reduction in assessed value = $1,620 in annual tax savings — recurring each year until the next reappraisal cycle.

The Bottom Line

Texas property tax protests are not adversarial, they're expected. The system is designed for property owners to participate. If you haven't protested in the last 2–3 years — or ever — this May's deadline is the time to start.
