How to Protest Property Taxes: A Texas Homeowner's Guide

TL;DR

In Texas, you "protest" your property taxes rather than "appeal" them. File your protest with the county appraisal district by May 15 or within 30 days of receiving your notice, whichever is later. The process starts with an informal hearing with an appraiser, then moves to the Appraisal Review Board (ARB) if needed. Texas has some of the highest success rates in the country, with 60-70% of protests resulting in a reduction.

Texas Property Tax Protests: What Makes Them Different

Texas uses different terminology than most states. What other states call an "appeal," Texas calls a "protest." What other states call a "review board," Texas calls the "Appraisal Review Board" or ARB. The process is similar in concept but different in details, and it is one of the most homeowner-friendly systems in the country.

Every Texas homeowner has the right to protest their property's appraised value each year. The county appraisal district (CAD) sets your value, and you can challenge it through a structured process that starts informal and becomes more formal only if needed.

The Texas Protest Timeline

Step	When	What Happens
Appraisal notices mailed	April (varies by county)	CAD sends your Notice of Appraised Value
Protest deadline	May 15 or 30 days from notice	File Form 50-132 with your CAD
Informal hearing	Weeks after filing	Meet with an appraiser to discuss your value
ARB hearing	If informal fails	Present your case to the review board
Decision	Within weeks of ARB	Written order with the board's determination
Further appeal	60 days after ARB	Binding arbitration or district court

Step 1: Review Your Notice of Appraised Value

Your notice arrives in April (exact timing varies by county). It shows your property's new appraised value, the homestead cap value (if applicable), and instructions for filing a protest.

Check these items:

Market value - Does this match what your home would actually sell for?
Homestead cap - If you have a homestead exemption, your assessed value cannot increase by more than 10% per year, regardless of appraised value.
Property details - Square footage, bedroom/bathroom count, year built, and property description.
Exemptions - Make sure your homestead and any other exemptions are showing.

If your appraised value jumped significantly or seems higher than comparable homes in your area, you have grounds to protest.

Step 2: File Your Protest

Filing is straightforward. You need Form 50-132 (Notice of Protest), available on your CAD's website. Most Texas counties now accept online filings.

The form asks for:

Your name and property address
Your property ID number (on your notice)
The reason for your protest (check the "value is over market value" box at minimum)
Whether you want an informal hearing first (always say yes)

Deadline: May 15 or 30 days from the date your notice was mailed, whichever is later. Do not wait until the last day.

What Reasons to Check on the Form

The form lists several protest grounds. The most common and effective are:

"Value is over market value" - Your primary argument. Always check this one.
"Value is unequal compared with other properties" - Useful if similar properties on your street are appraised lower. Also check this one.
"Property description is incorrect" - If the CAD has wrong square footage, room count, or other errors.

Check all boxes that apply. There is no downside to checking multiple reasons.

Step 3: Prepare Your Evidence

Evidence wins protests. Opinions do not. Gather these materials before your hearing:

Comparable Sales (Most Important)

Find 3-5 similar homes that sold recently for less than your appraised value. Use HAR.com, Zillow, Redfin, or your CAD's website. For detailed instructions, see our comparable sales guide.

Equity Comparables

Texas allows "unequal appraisal" arguments. Look up the appraised values of similar homes in your neighborhood on your CAD's website. If your home is appraised significantly higher than comparable nearby properties, that is a valid protest ground.

Property Condition Documentation

Photos of needed repairs, structural issues, or deferred maintenance. Contractor estimates for repair costs add weight.

Property Record Errors

Check your property details on the CAD website. If anything is wrong (square footage, features, condition rating), document the error.

Step 4: The Informal Hearing

This is where most Texas protests get resolved. The informal hearing is a one-on-one conversation with a CAD appraiser, not a formal proceeding.

What to expect:

You meet with an appraiser (in person, by phone, or online)
You present your evidence
The appraiser may show you their evidence
If you reach an agreement, the appraiser offers a settlement value
You can accept or decline the settlement

Tips for the informal hearing:

Be polite and professional
Present your comps first, in a clear table format
If the appraiser offers a settlement, you do not have to accept immediately. You can ask to think about it.
If you decline the settlement, your case automatically goes to the ARB hearing

Many homeowners get a satisfactory reduction at this stage and never need to go further.

Step 5: The ARB Hearing (If Needed)

If the informal hearing does not produce an acceptable result, your case goes to the Appraisal Review Board. This is a panel of local citizens appointed to hear protests.

The ARB hearing is more structured than the informal hearing but still fairly casual compared to a courtroom. Here is what happens:

You are sworn in
You present your evidence (5-15 minutes)
The CAD representative presents theirs
Board members may ask questions
The board deliberates and issues a written decision

Bring printed copies of your evidence for each board member (usually 3), the CAD representative, and yourself. Present your comparable sales and equity data clearly. See our hearing tips guide for presentation advice.

Step 6: After the ARB Decision

If the ARB reduces your value, you win. The new value takes effect for the current tax year.

If you are not satisfied with the ARB decision, you have two more options:

Binding Arbitration

Available for residential properties appraised at $5 million or less. You file a request with the CAD and pay a $500 deposit (refunded if you win). An independent arbitrator reviews the case and makes a binding decision.

District Court

You can file a lawsuit in district court within 60 days of the ARB decision. This requires an attorney and is typically only cost-effective for high-value properties.

The Homestead Cap: Your Built-In Protection

If you have a homestead exemption in Texas, your assessed value (the value your taxes are actually based on) cannot increase by more than 10% per year. This "cap" is separate from the appraised value.

Example: If your assessed value was $300,000 last year, the maximum this year is $330,000, even if the CAD appraises your home at $400,000. The cap provides automatic protection against large annual increases.

However, the gap between your capped value and your appraised value matters. If you sell your home, the new owner starts from the full appraised value with no cap benefit. And if the appraised value keeps climbing, the 10% annual cap increases compound over time.

That is why protesting is still valuable even with the homestead cap. Getting the appraised value reduced narrows the gap and limits future cap increases.

Texas-Specific Exemptions to Claim

While protesting, make sure you are claiming all exemptions available to you:

General homestead - $100,000 off your home's value for school district taxes (as of 2024)
Over-65 - Additional $10,000 off plus school tax freeze
Disabled - Additional $10,000 off
Disabled veteran - $5,000-$12,000 based on disability rating, or full exemption at 100% disability

Online Protest Platforms

Many Texas counties now offer online protest filing and virtual hearings. Harris County, Dallas County, Travis County, and Bexar County all have online systems. Check your CAD's website for digital filing options.

The online process is the same as in-person: file your protest, upload evidence, attend a virtual informal hearing, and proceed to virtual ARB if needed.
