Every spring, the same envelope lands in Texas mailboxes: the Notice of Appraised Value from the county appraisal district. For a lot of homeowners, the number inside is higher than last year — sometimes a lot higher — and the first instinct is to sigh, file it away, and brace for a bigger tax bill. That is the costly mistake. A property-tax protest is one of the few ways an ordinary Texan can push back on a government number, and it is free to file.
This guide walks through the protest start to finish: the deadline you cannot miss, the evidence that actually moves a value, and what to expect at an informal meeting and a formal hearing. None of it requires a lawyer or a paid firm. The Texas Comptroller publishes the rules and the forms, and your county appraisal district handles the rest.
Know the deadline first
The statutory deadline to file a written protest is May 15, or 30 days after the appraisal district mailed your Notice of Appraised Value, whichever is later, under the Texas Property Tax Code. If the deadline falls on a weekend or legal holiday, it rolls to the next business day. The exact date for your property is printed on the notice itself — read it. Miss the deadline and you generally lose your right to protest that year, so this is the one step you cannot put off. The Comptroller summarizes the timeline in its property-tax protest guide.
File the protest — it is a one-page form
You file using Comptroller Form 50-132, the Notice of Protest, or your appraisal district’s online portal. Most large Texas districts — including those serving Harris, Dallas, Tarrant, Bexar, and Travis counties — accept online filing, and many invite you straight into an online settlement system. On the form, you check the reasons you are protesting. The two that matter most for a typical homeowner are “value is over market value” and “value is unequal compared with other properties.” Check both; they give you two independent paths to a reduction.
Build evidence that the appraisal district takes seriously
Appraisers respond to comparable sales, not to how you feel about your taxes. Your job is to show that similar homes near you sold for less than your appraised value, or that comparable homes are appraised lower than yours. Useful evidence includes:
- Recent sales of comparable homes in your neighborhood — same size, age, and condition. You can request the district’s own evidence packet, which often lists the comps it used.
- Photos of problems that lower value: a cracked foundation, an old roof, deferred maintenance, a busy road behind the fence.
- Repair estimates from a contractor for any major issue, dated as of January 1, the appraisal date.
- A recent appraisal or closing statement if you bought the home recently for less than the district’s value.
Under the Texas Property Tax Code, you are entitled to request the evidence the district intends to use against you before the hearing. Ask for it. It tells you exactly what you are arguing against.
Take the informal meeting
Most protests never reach a formal hearing. Texas appraisal districts offer an informal meeting — by phone, online, or in person — with a staff appraiser. This is where the majority of reductions happen. Bring your comps and your photos, stay polite and specific, and propose a number. If the appraiser’s offer is reasonable and supported, you can accept it on the spot and you are done for the year. If the offer is not good enough, you decline and move to the formal hearing. You lose nothing by trying the informal route first.
The formal hearing before the ARB
If you do not settle informally, you appear before the Appraisal Review Board (ARB), a panel of local citizens independent of the appraisal district. The hearing is short — usually 15 to 30 minutes. You present your evidence, the district appraiser presents theirs, and the panel decides on a value. The Comptroller’s office publishes the “Property Taxpayer Remedies” guide, which lays out your rights at the hearing. Keep your presentation factual: here are three comparable sales, here is the condition of my home, here is the value those facts support.
If you still disagree after the ARB
An ARB decision is not necessarily the end. Depending on your property and the size of the disputed value, Texas law gives you options to appeal further — through binding arbitration administered by the Comptroller, an appeal to district court, or, for certain properties, the State Office of Administrative Hearings. The Comptroller describes these post-ARB remedies in its official materials. For most homeowners these steps are not worth the cost or effort, but they exist, and knowing they exist sometimes strengthens your hand earlier in the process.
What “winning” really looks like
Winning a protest rarely means a dramatic cut. More often it means shaving several thousand dollars off your appraised value, which translates into a modest but real reduction on the tax bill that arrives in the fall. And because Texas places a 10 percent annual cap on appraisal increases for a homesteaded property — described by the Comptroller — a successful protest can also lower the base from which future increases are measured. The compounding effect over several years is the part most people overlook.
The two arguments that win most often
Almost every successful homeowner protest rests on one of two arguments, and it pays to understand which fits your situation. The first is market value: you contend the district’s number is higher than what your home would actually sell for, and you prove it with recent sales of comparable homes that sold for less. The second is unequal appraisal: even if your value is arguably defensible on its own, you show that comparable homes in your area are appraised for less than yours, which violates the principle that similar properties should be treated alike. Texas law gives you the right to win on either ground, which is why checking both boxes on the protest form matters. The Comptroller’s taxpayer remedies guide explains both standards.
A common mistake that sinks protests
The most frequent reason a protest fails is that the homeowner argues the wrong thing. The Appraisal Review Board does not have the power to lower your tax rate, change how the money is spent, or grant relief because the bill is hard to afford — those are decisions for elected officials and other programs. The board’s only job is to decide whether the appraised value is correct. An argument built on “my taxes are too high” or “I’m on a fixed income” will not move a value, however sympathetic. An argument built on three comparable sales and photos of a failing roof will. Keep the case anchored to value, and you keep it on the only ground the board can act on.
A few habits that pay off
File every year your notice shows an increase, even a small one. Keep a folder of neighborhood sales as you hear about them. Photograph maintenance issues when they happen, not the night before the hearing. And be wary of unsolicited pitches from firms promising guaranteed reductions for a cut of your savings — the protest is free to do yourself, and the Texas Attorney General regularly warns about property-tax solicitation schemes. The system is set up so a regular homeowner, with an afternoon and a stack of comparable sales, can hold the line on a government number. Use it.
