Protesting your tax appraised value is the most direct way Texas homeowners can push back on a tax bill, and the process follows a predictable path from your appraisal notice to a written order.
- A protest challenges your tax appraised value only. Record errors and exemption problems are handled directly with your county appraisal district and are separate actions.
- The filing deadline is May 15 or 30 days after your appraisal notice is mailed, whichever falls later.
- Closed comparable sales from the 12 months preceding January 1, adjusted equity comps, and written contractor estimates for pre-January 1 condition issues carry the most weight.
Protest every year regardless of whether the number looks high, because the value you accept this spring becomes the baseline your county builds on next spring.
Texas property taxes start with a single number, and homeowners have a legal right to challenge it. This Texas property tax protest guide walks through the full sequence, from the spring notice to the written order that closes your case. Property tax help for Texas homeowners starts there, because every stage carries its own deadline and its own kind of evidence.
Relief has arrived in real terms. Statewide, the aggregate effective property tax rate fell 22.11 percent between 2019 and 2025, driven mostly by larger homestead exemptions and compressed school tax rates, according to the Texas Real Estate Research Center at Texas A&M University. That relief only reaches you in full if the number underneath it is accurate, since exemptions and tax rates are both applied to your tax appraised value.
Where Does a Texas Property Tax Protest Guide Begin?
Start where the appraisal district starts: the number it assigns to your home as of January 1. Texas law requires districts to value taxable property at 100 percent of market value as of that date, a valuation snapshot rather than the day anything is calculated. The CAD builds that estimate through mass appraisal, running thousands of properties through one statistical model, which is efficient for a county and imprecise for any individual house.
Your appraisal notice and tax bill come from two different offices. The appraisal district sets your tax appraised value and mails the Notice of Appraised Value. The county tax assessor-collector mails the bill months later, after local taxing entities adopt rates. You can protest the first, never the second.
Protesting is worth doing every single year, whether or not the number looks high. A value that seems reasonable can still sit above what the market supports, and the only way to find out is to test it against evidence. Exemptions are the other piece of your bill you can influence, and they run on a separate track.
Which Number Are You Actually Protesting?
On the notice, the figure you are protesting appears on the line labeled “Market Value.” Fort Bend Central Appraisal District explains the values printed on your notice this way: Market Value is what the district believes the property is worth as of January 1, while the capped figure below it is limited by the homestead exemption and generally cannot rise more than 10 percent a year. That top line is the figure this guide calls your tax appraised value, since it is the number a protest challenges. Knowing tax appraised value versus market value is the difference between a focused argument and a scattered one.
What Is Not Part of the Protest Process?
Two common homeowner problems look like protest issues and are not. If the district has your square footage, room count, or year built wrong, that correction goes to the CAD as an administrative request, and the district often verifies it or re-measures, so it is rarely instant. Exemptions follow the same path. Under Senate Bill 1801, chief appraisers must review each homestead exemption at least once every five years, and Collin Central Appraisal District notes that homeowners do not need to reapply unless the district asks by mail. Missing exemptions, over-65 filings, and verification responses all go straight to your appraisal district, and none of it is a protest action.
What Changed in Texas Property Tax Law Recently?
Voters reshaped the exemption landscape in November 2025, and the changes were backdated rather than delayed. Propositions 11 and 13 raised the general school district homestead exemption from $100,000 to $140,000 and lifted the add-on for elderly or disabled homeowners from $10,000 to $60,000, bringing their combined exemption to $200,000. The constitutional text attached to Proposition 11 took effect for the tax year beginning January 1, 2025, so the benefit reached 2025 bills. The full picture of Texas property tax relief is worth a read if you have not claimed what you qualify for.
One change cuts the other way. The 20 percent circuit breaker limitation on rentals, second homes, and smaller commercial property was authorized only for the 2024, 2025, and 2026 tax years. Owners should plan as though it is retiring, which makes the tax appraised value on non-homestead property more consequential. These annual value increase limits explain how caps and protests interact.
What Does the Appraisal Protest Process Look Like Across the Year?
The process runs on a calendar that barely shifts from year to year, and seeing the whole arc explains why a spring deadline decides a bill you will not open until fall.
- January 1. Valuation date. Your property is appraised as it stood on this day.
- April 1 (homesteads) or May 1 (other property). Appraisal districts mail Notices of Appraised Value.
- May 15. Protest deadline, or 30 days after your notice was mailed, whichever is later.
- June. Informal conferences with appraisal district staff.
- July and August. Formal ARB hearings, followed by certification of the appraisal roll.
- September and October. School districts, cities, counties, and special districts adopt tax rates.
- October and November. The county tax assessor-collector mails tax bills.
- January 31. Payment due for the prior tax year.
Those dates come from statute, not local custom. The protest and hearing rules confirm the April 1 and May 1 mailing dates, the May 15 filing window, and that boards should finish most hearings by July 20, with larger counties running later. The Texas A&M analysis cited above sets the rate-adoption and bill-mailing deadlines, and Tax Code Section 31.02 makes taxes delinquent February 1. County variation is covered in this property tax protest deadlines breakdown.
How to Protest Property Taxes in Texas: Eight Steps
The heart of any Texas property tax protest guide is the sequence itself. Learning how to protest property taxes is mostly a matter of doing the right thing at the right point on that calendar. The eight steps below cover the full arc for a residential property.
Step 1: Read Your Notice of Appraised Value Line by Line
Open the notice the day it arrives, confirm the property description, and compare this year’s tax appraised value against last year’s. Note the deadline printed on it, since a late mailing can push your own deadline past May 15. If an exemption looks wrong or missing, raise that with the CAD directly rather than folding it into the protest, since the two are handled on separate tracks.
Step 2: Choose Your Grounds
Texas gives residential owners two grounds, and you can claim both. A market value protest argues that your tax appraised value exceeds what your home would sell for as of January 1. An unequal appraisal protest argues that your property is appraised at a higher share of value than comparable properties, which the Texas Constitution’s equal and uniform standard prohibits. Both sit in Tax Code Chapter 41, which also puts the burden on the district to establish your value. Checking both boxes on Form 50-132 preserves the widest range of evidence and the fullest appeal rights.
Step 3: Build Your Evidence File
Evidence decides cases. Closed sales of genuinely comparable homes from the 12 months preceding January 1 form the backbone of a market value argument, and each must be adjusted for size, age, lot, condition, and features. Sale prices are not printed on your notice and are not always easy to verify in Texas, which is why an unadjusted glance at a neighbor’s number carries no weight in a hearing room.
Condition matters too, provided the problem existed before January 1. Written contractor estimates for foundation work, roof replacement, or drainage repair document what a statistical model cannot see, and recent closing documents help if you bought near the valuation date. A closer look at what evidence holds up is worth your time.
Step 4: File the Protest
Filing a property tax protest in Texas costs nothing, since Tax Code Chapter 41 bars districts from charging for a notice of protest. Most accept protests through an online portal, and filing your protest online is the fastest route in the largest counties. Some counties want evidence at the time of filing, so check your district’s instructions rather than assuming you can supply it later.
Step 5: Request the District’s Evidence
This step gets skipped constantly, and it is one of the most useful. The Comptroller’s guidance on protest and appeal procedures explains that you may inspect and copy the data, schedules, and other information the chief appraiser plans to introduce, and that the district must notify you of that right in advance. Once you see the district’s comparable sales, you can prepare a specific rebuttal rather than a general objection.
Step 6: Work the Informal Conference
Most districts offer a one-on-one meeting with a staff appraiser before the formal hearing. Bring your full file and listen to how the appraiser built the number. If the CAD extends a settlement offer you consider fair, you can accept it. If not, your hearing rights remain intact so long as you filed on time.
Step 7: Present at the Formal ARB Hearing
The Appraisal Review Board is an independent citizen panel, not part of the appraisal district. You present first, the district responds, and both sides may offer rebuttal. Bring copies for every panel member and keep it tight, since panels run on a clock. Stay on property value: the board cannot weigh your household finances, your opinion of the tax rate, or the cost of living, and raising those subjects burns time you need for comparable sales. These tips for protesting property taxes can sharpen your presentation before you walk in.
Step 8: Review the Order and Weigh an Appeal
After deliberating, the ARB mails a written Order of Determination by certified mail. That order closes the appraisal protest process for the year unless you appeal, and three routes exist: state district court, the State Office of Administrative Hearings for qualifying properties, and regular binding arbitration.
What Can You Do Between Protest Seasons?
Fall and winter are quiet months in the appraisal protest process, which is exactly when a Texas property tax protest guide earns its keep. What you gather now becomes the file you open in April.
- Track closed sales of comparable homes through reliable channels, recording the sale date, size, age, and condition of each.
- Document condition problems as they appear, since only issues present before January 1 count for that tax year, and get written contractor estimates for repairs you have not yet made.
- Keep closing documents accessible if you purchased recently.
Two other off-season tasks are worth doing and are not protest preparation. Correcting a CAD record error and filing or verifying an exemption go directly to the appraisal district. They still matter, because next spring’s protest argues against whatever baseline data the county holds.
Should You Protest on Your Own or Bring in Help?
Knowing how to protest property taxes and having time to do it are two different things. Everything in this Texas property tax protest guide is something a homeowner can handle alone, and plenty do it well. The real cost is hours, since adjusted comparable sales, evidence requests, and two rounds of hearings can absorb the better part of a workweek. Homeowners who would rather not spend it hire licensed, local property tax professionals who work their county’s appraisal district every season.
If you go that route, the fee structure tells you more about a firm than any marketing page. A hybrid model, meaning a modest upfront fee plus a percentage of savings, tends to be the best value, because that upfront commitment funds a full protest on every property rather than only the easy ones. A pure contingency model pays a firm only when a reduction lands, which creates a quiet incentive to skip files that look difficult. Ask whether a firm takes every property all the way through, and be wary of anyone quoting a number before looking at your home. No company can legally promise a specific reduction.
Frequently Asked Questions
Can my tax appraised value go up because I filed a protest?
No. Under Tax Code Chapter 41, the board may not set a protested property’s value higher than the figure in the appraisal records the chief appraiser submitted, unless the owner asks for and agrees to it. The worst outcome is the value staying where it started.
Is a property tax protest in Texas worth filing if my value went down?
Yes. A lower number is not automatically a correct number, and running the process is the only way to know whether your value is fair. Protesting annually keeps your baseline as low as the evidence supports, which compounds over future years.
Will a reduction lower my bill right away?
For most homeowners, yes, because a lower tax appraised value flows into a lower taxable value. A narrower group of long-tenured homestead owners may find the 10 percent cap already holds their taxable value below their tax appraised value, so a reduction protects the future baseline rather than the current year’s bill. Protesting is still worthwhile there, since the baseline is what next year’s increase is measured from.
What happens if I miss the May 15 deadline?
The ARB may accept a late protest if you show good cause and file before the board approves the appraisal records, but that path is narrow and discretionary. File on time.
What happens after the ARB hearing?
The ARB mails a written Order of Determination by certified mail. That order closes the protest for the year unless you appeal to state district court, the State Office of Administrative Hearings for qualifying properties, or regular binding arbitration. Our guide to what happens after you protest walks through each outcome.
What evidence carries the most weight in a protest?
Closed sales of genuinely comparable homes from the 12 months preceding January 1, each adjusted for size, age, lot, condition, and features, plus written contractor estimates for condition problems that existed before January 1. Our guide to comparable home sales explains how to choose and adjust them.
