How to Protest Property Taxes in Texas: 2026 Step-by-Step Guide

The 6 Steps to Win Your Texas Property Tax Protest in 2026

If you own property in Texas, you can protest your assessment. The process is designed for homeowners to represent themselves. But knowing what to do — and when — is the difference between a successful protest and accepting whatever the appraisal district decided your property is worth.

This guide walks through every step in the 2026 Texas property tax protest process. We'll cover what to file, when to file, what evidence wins, how informal reviews work, and what happens at the Appraisal Review Board (ARB) hearing.

Step 1: Receive Your Notice of Appraised Value

Every county appraisal district (CAD) in Texas mails Notices of Appraised Value in April through early May. Your notice tells you three things:

• Your property's appraised value for 2026
• The taxable value (after exemptions)
• Your protest deadline

Open the notice. Compare the appraised value to what your home would actually sell for today. Not what you hope it's worth — what a buyer would realistically pay. If the CAD's number is higher, you have grounds to protest.

Haven't received your notice yet? Search your property on your county's appraisal district website. Major districts like dallascad.org (Dallas), hcad.org (Harris), tad.org (Tarrant), traviscad.org (Travis), and bcad.org (Bexar) let you look up your assessment online.

Step 2: File Your Protest Before May 15, 2026

The 2026 Texas protest deadline is May 15, 2026 — or 30 days after your Notice was mailed, whichever is later. This deadline is hard. Texas Tax Code §41.44 doesn't bend for "I forgot" or "I was busy."

The fastest way to file is online through your CAD's portal. Most major Texas CADs use one of three systems:

• Dallas County (DCAD): uFile portal at dallascad.org
• Harris County (HCAD): iFile portal at hcad.org
• Tarrant County (TAD): Online filing at tad.org
• Travis County (TCAD): Online filing at traviscad.org
• Many smaller CADs (Ellis, Johnson, Comal, etc.): True Prodigy Online Protest portal

Filing takes under 10 minutes. You'll need:

• Your property account number (printed on your Notice)
• A reason for protest (most homeowners check both "value is over market value" and "value is unequal compared to other properties")
• Your opinion of value (a starting point for negotiation, not a binding number)

You don't need evidence to file. The protest itself preserves your right to a hearing. You can build your case in the weeks after filing.

What If I Miss May 15?

Texas Tax Code §41.411 allows a late protest once every five years for homestead properties — but only if you can prove you never received proper notice. This is rarely granted. If you miss the deadline with no good cause, your 2026 value is locked for the entire year.

Don't wait until May 14. File now, build your evidence later.

Step 3: Gather Your Evidence

After you file, you have weeks (sometimes months) before your informal review. Use that time to build your case. The strongest Texas protest evidence falls into three buckets:

Comparable Sales (Comps)

Pull recent sales of similar properties within 1–2 miles of your home, sold in the 12 months before January 1, 2026. "Similar" means same neighborhood, similar square footage, similar age, similar quality. The closer the match, the better the evidence.

Free sources for comps: your CAD's website, Zillow, Realtor.com, Redfin. Paid services pull MLS data with adjustments. For high-stakes protests, MLS data with agent verification is the gold standard.

Property Condition Documentation

Photos of foundation cracks (Texas clay soil causes systematic foundation issues in Ellis, Johnson, Tarrant, and Dallas counties), water damage, deferred maintenance, outdated systems, or structural issues. Repair estimates from licensed contractors strengthen the case.

Functional obsolescence (e.g., a 1980s floor plan that doesn't match modern buyer demand) and economic obsolescence (e.g., a nearby commercial development hurting residential values) are also valid arguments.

Unequal Appraisal Evidence

Under Texas Tax Code §41.43(b)(3), you can challenge your assessment on the grounds that similar properties in your neighborhood are assessed for less. Pull the assessed values of 5–10 nearby comparable properties from your CAD's website. If they're systematically valued lower than yours, that's powerful evidence.

You can argue both market value AND unequal appraisal simultaneously. Doing so strengthens your case at both informal review and ARB hearing.

Step 4: Attend the Informal Review

Most Texas property tax protests resolve at the informal review — a meeting (in person or by phone) with a CAD staff appraiser. This usually happens 4–8 weeks after filing.

Under HB 1533 (passed by the Texas Legislature in 2023), the CAD must share its evidence with you at least 14 days before your hearing. This is huge. You see exactly what data the CAD is using to justify your value before you walk in. Use those 14 days to find weaknesses in their case.

At the informal review, you'll present your evidence. The appraiser may offer a settlement (a lower value). If you agree, you sign and you're done. Your tax bill drops accordingly.

Informal Review Success Rates by Major County (2024)

• Bexar County: 99.9%
• Tarrant County: 98.7%
• Travis County: 98.6%
• Harris County: 93.5%
• Guadalupe County: 93%
• Dallas County: 80–90%
• Ellis County: 74%
• Galveston County: 66%

The point: in nearly every Texas county, most homeowners who show up to the informal review with evidence win a reduction.

Step 5: ARB Hearing (If Needed)

If the informal review doesn't produce a settlement you accept, your case proceeds to the Appraisal Review Board (ARB) — a formal panel of appointed members independent from the CAD.

At the ARB hearing, you present your case (10–15 minutes), the CAD presents theirs, and the board makes a binding decision. Most ARB hearings happen between May and August.

You have nothing to lose by going to ARB. Texas law (since 2019) prevents your value from being raised as a result of protesting. The CAD will sometimes offer larger informal-stage reductions specifically to avoid ARB hearings — use that as leverage.

Step 6: Receive Your Decision and Adjusted Tax Bill

If the informal review settles your case, you receive a written notice of the new assessed value within a few weeks. If your case goes to ARB, the board issues a written order after the hearing.

The reduction applies to your 2026 tax bill. You'll see the savings reflected on the bill mailed in October 2026, due January 31, 2027.

Better still: a successful protest lowers your baseline assessed value, which carries forward into future years. Missing one year's protest doesn't just cost you 2026 — it inflates the starting point for 2027 and beyond.

Texas Property Tax Protest by Major Region

DFW Metro

The DFW metro is the highest-volume protest region in Texas. Dallas (DCAD), Tarrant (TAD), Collin (CCAD), and Denton (DCAD) all face aggressive valuations as DFW continues to grow. Outer-ring counties — Ellis, Johnson, Rockwall, Kaufman, Parker — face spillover growth and even more inflated assessments.

Houston Metro

Harris (HCAD) is the largest CAD in Texas. File early to avoid backlogs. Surrounding counties — Fort Bend (FBCAD), Montgomery (MCAD), Galveston, Brazoria — see strong protest results too.

Austin Metro

Travis (TCAD), Williamson (WCAD), and Hays (HCAD) face some of the most aggressive valuations in Texas due to Austin's hot market. Protest success rates above 78% across the region.

San Antonio Metro & Central Texas

Bexar (BCAD) has the highest success rate in Texas at 99.9%. Comal and Guadalupe in the spillover markets also see strong results. Central Texas's Bell County (Killeen/Temple) hit a record $1.02B in protested value in 2024.

DIY vs. Hire a Pro

You can DIY a Texas property tax protest. The process is designed for homeowners. But the win rates differ:

• DIY success rate: 25–40% in most counties
• Professional success rate: 73–99.9% depending on county
• Average DIY reduction: Smaller, often half of professional reductions
• Average professional reduction: $1,300–$3,700 per protest

The reason isn't magic. Professionals know which comparable sales the ARB will accept, how to structure unequal-appraisal arguments, when to settle informally, and when to push to ARB. They also handle filings, paperwork, and hearings — saving you 10–20 hours of work per property.
