How to Protest Your Property Tax in Texas (Without Giving 25% to a Middleman)

If you live in Texas and you have not protested your property tax appraisal in the last few years, you have probably overpaid your county by several thousand dollars per year. This is not a hot take. The protest system exists specifically because the state recognizes that mass appraisal is imprecise — and Texas homeowners who push back successfully reduce their bills somewhere between 30% and 60% of the time, depending on the county and how prepared they show up.

The catch: most of the firms advertising "we'll protest for you" charge between 25% and 40% of your first-year savings. On a $200,000 reduction in appraised value, that's roughly $500 to $1,200 leaving your pocket each year — for a process that, if you have the right packet in hand, takes less than two hours of your time and zero specialized knowledge.

This guide is the plain-English version of the protest process. Real statutes, real deadlines, real evidence standards, and an honest assessment of when DIY makes sense and when paying for help is the right call.

The actual math: what protesting saves you

Texas property tax rates vary by county and by the taxing entities within them (school district, county, city, hospital district, water district, etc.), but the combined rate for a typical Texas homeowner falls between 2.0% and 2.8% of assessed value per year. For a home appraised at $400,000, that's $8,000 to $11,200 of annual property tax — every year, indefinitely.

A successful protest that reduces your appraised value by 15% — a modest, commonly achievable result — saves you about $1,200 to $1,680 per year. A reduction of 30%, which is well within reach when your comps support it, saves $2,400 to $3,360. Annually. Compounded over the time you own the home, the lifetime value of a single successful protest typically runs $20,000–$60,000.

The contingency-fee firms know this. Their entire business model depends on it. A 25% cut of a $1,500 annual reduction is $375 in their pocket per year per customer, and they protest thousands of properties annually with mostly the same automated comp pulls. It is an enormously profitable business — built on a piece of work that, if you understand the system, you can do yourself in an afternoon.

The two grounds you can protest on

Texas Tax Code §41.41(a) lists the grounds on which a property owner may protest. The two that matter for almost every residential protest are subsections (1) and (2):

These are independent. You can protest on one, the other, or both. Most successful protests check both boxes on the Form 50-132 — it costs nothing extra and gives you flexibility during negotiation.

Which one to lead with

Texas is a non-disclosure state. Sale prices are not part of public records. Unless you have access to the MLS (which generally means a licensed real estate professional), proving "excessive market value" with hard sale data is difficult. You can still argue market value using your own recent purchase price (if you bought below the appraisal), a private appraisal you commissioned, or photographic evidence of condition issues that reduce value — but these tools are uneven and homeowner-specific.

Unequal appraisal is the workhorse argument for most Texans. The comp data you need is public — every county appraisal district publishes the appraised value of every property on its rolls. You just have to gather it, compute the median dollars-per-square-foot for a reasonable set of comparable homes, and show that your property exceeds that median. Math the county can argue with, but cannot dismiss as inadmissible.

Timeline: every important date

The Texas protest calendar has the same shape every year — but missing any of these dates can cost you the year. Print this and put it on your fridge in January.

Date	What happens	What you do
January 1	The "appraisal date" — the legal valuation date for the entire tax year	Document any condition issues (photos, repair quotes) that exist as of this date
April 1 – April 30	Most CADs mail "Notice of Appraised Value" to property owners	Open the envelope immediately — your protest clock starts ticking
April 30	Statutory deadline for homestead exemption application (Form 50-114) for the current year, before back-claim window applies	File Form 50-114 if you bought the home in the last 24 months
May 15 OR 30 days after notice mailed, whichever is later	Deadline to file Form 50-132 (Notice of Protest)	File your protest. Late = no protest this year. Period.
May – July	Informal reviews and ARB hearings scheduled by your CAD	Show up prepared. This is where the actual decision happens.
July 25	Most ARB decisions issued by this date (varies by county)	Decide if you accept the ARB ruling or pursue further appeal
August / September	Tax rates set by taxing entities (school district, county, city)	Optional advocacy: attend taxing-entity rate-setting meetings if your district is hiking rates
October	Tax bills issued	Verify your bill reflects the protest outcome
January 31	Property taxes due (penalties begin February 1)	Pay on time even if you're still in appeal

The single most important date on this table is May 15. Miss it and you have no recourse for the year, no matter how strong your case. Most CADs accept the protest via online portal, mail, or in person — and most will let you file with just a sentence ("I protest on grounds of excessive market value and unequal appraisal under Texas Tax Code §41.41") and add detailed evidence later. If your CAD's portal is up and your notice has arrived, file the protest the same day. You can always withdraw it later; you can never file it late.

The five-step DIY process

Here is the entire protest process, stripped of mystery. Total time investment for a prepared homeowner: 2 to 4 hours, spread over a few weeks.

1Get your appraisal notice and verify the basics

When your "Notice of Appraised Value" arrives, check four things:

• Your name and the property address are correct. Sounds dumb. Errors happen often enough to mention.
• Your homestead exemption is listed (if you've filed Form 50-114). The notice will show "homestead cap loss" if the cap is active. If it's missing and you bought in the last two years, read our homestead piece — this alone may be worth more than your protest.
• The square footage, year built, and bedroom/bathroom count on file match reality. Pull your CAD record online and compare to your house. If the CAD thinks you have a finished basement you don't, or thinks your 1,800 sqft house is 2,100, file a correction — this is a faster fix than a full protest.
• Compare this year's appraised value to last year's. If the increase exceeds 10% and you have an active homestead exemption, the §23.23 cap should limit your assessed value regardless. Verify the math on the notice.

2File Form 50-132 to preserve your right to protest

The Texas Comptroller's Form 50-132 (Notice of Protest) is one page. Submit it to your county appraisal district by May 15. Most CADs have online portals; a few still want mail or in-person. Check both "Value is over market value" and "Value is unequal compared with other properties" as your grounds — you can lean on either argument depending on what evidence develops.

You do not need your evidence packet ready at the time of filing. You just need the form on file before the deadline.

3Build your evidence packet

This is the work. A strong unequal-appraisal packet contains:

• A subject-property snapshot: address, account number, square footage, year built, current appraised value, dollars-per-square-foot
• 5–15 comparable properties pulled from your county's CAD search: same neighborhood, within ±25% of your square footage, within ±10 years of your year built. List each with its address, appraised value, sqft, and dollars-per-square-foot.
• The median dollars-per-square-foot of those comps
• Your proposed appraised value = (median $/sqft) × (your sqft). This is what you're asking the ARB to grant.
• The single most damning comparable: a side-by-side with one neighbor's property that is similar or better than yours and yet appraised meaningfully lower. Visceral always beats statistical.
• Photographs of any condition issues: foundation cracks, roof damage, dated kitchen/bath, deferred maintenance. Date-stamp them.
• Repair estimates from contractors for documented condition issues
• Recent purchase documents if you bought below the appraised value — your closing disclosure is admissible as evidence under §41.43(a-3)
• An independent appraisal report if you have one (typically $300–$600 to commission privately)
• A clear methodology page explaining how you selected your comps and computed the median

Assemble all of this into a single PDF. Most CAD portals accept evidence uploads up to 25 MB. The packet should look like a professional submission — appraisers see hundreds of these per cycle and pattern-match on quality. A clean, organized PDF earns more respect than the same evidence dumped as a stack of loose pages.

4Request the CAD's evidence packet (and read it)

Under Texas Tax Code §41.461, the county appraisal district is required by law to provide you with the evidence they intend to use against you, at least 14 days before your formal ARB hearing. You request it; they must comply. The request is short — most CADs have a one-click button in the protest portal, or accept a one-line email.

This is a substantial advantage that many homeowners never use. The CAD's evidence often reveals weak comps that you can rebut, methodology shortcuts you can point out, or simple arithmetic mistakes. If their packet includes a comparable that just sold and you can show your house is in worse condition, you have a fact-based response ready.

5Show up to the hearing prepared

This is the only part that requires showing up in person (or virtually). Most informal reviews are 10-to-15 minute conversations. The formal ARB hearing, if it gets that far, is typically 20-to-45 minutes. Both are conducted in plain English. No lawyer is required and no specialized vocabulary is needed.

What matters is that you walk in with the packet, calm body language, and the specific number you want — your proposed appraised value, derived from your comp analysis. You do not negotiate against yourself. You state the number. The appraiser counter-offers or accepts. You decide.

What evidence actually wins

Texas Appraisal Review Boards are made up of regular citizens. Many are retired. Most have day jobs entirely unrelated to real estate. They are not appraisers. They are not attorneys. They evaluate evidence in much the same way a juror would: clear, organized, factual presentations beat dense, jargon-heavy ones every time.

In rough order of persuasiveness

1. A recent arms-length purchase price below your appraisal. You bought the house six months ago for $375,000. The county now claims it's worth $440,000. You don't need a packet — you need a copy of your closing disclosure. (Texas Tax Code §41.43(a-3) explicitly recognizes this.)
2. A median-comp analysis with 8 to 15 nearby properties, properly bounded by square footage and year built, showing your property is significantly above the neighborhood median dollars-per-square-foot. Computed and labeled cleanly.
3. An independent appraisal report commissioned by you within the last 12 months.
4. A single, damning comparable — newer or larger or in better condition, yet appraised lower. Often more persuasive in person than statistical evidence.
5. Documented condition issues with photographs and repair quotes. Foundation cracks, roof damage, plumbing problems, dated finishes. The appraiser working from desk records cannot see your kitchen. Show them.
6. External factors that reduce value: adjacent vacant lots in disrepair, new commercial development affecting residential character, recent neighborhood crime increases, public-record code violations on neighboring properties.

What does NOT win

• "It feels too high." Feelings are not evidence.
• "I can't afford it." The ARB is legally barred from considering ability to pay (§41.43(d)).
• "Tax rates are too high." The protest is about value, not rates. Rates are set by taxing entities (school district, county, city), not the CAD.
• "My neighbor said..." Hearsay. Bring documented appraised values, not opinions.
• "Zillow says my house is worth less." Zillow's Zestimate is not admissible. The ARB will (rightly) ignore it.

The informal review is where most cases settle

Nearly every Texas county offers an informal review — a private meeting between you and a CAD appraiser before any formal ARB hearing. Roughly 60% to 80% of Texas property tax protests are resolved at this stage. The remaining 20-40% go to formal ARB.

Informal reviews are short and conversational. The appraiser has reviewed your evidence packet and has the CAD's records in front of them. The conversation typically follows this shape:

1. You state your proposed appraised value (the number you derived from your comp analysis). "I'm requesting an appraised value of $342,000 for tax year 2027 based on the median dollars-per-square-foot of 12 comparable properties in my neighborhood."
2. The appraiser looks at your packet and the CAD's own records. They may agree, partially agree, or counter-offer.
3. If they counter, you have three options: accept (and the protest is resolved), decline (and proceed to formal ARB), or counter back with adjusted reasoning. The conversation usually settles in 10-15 minutes either way.

You are not required to accept whatever the appraiser offers. If they propose a number above what your evidence supports, ask them to walk you through their reasoning. If their reasoning is weak, decline and proceed to formal ARB. You can always accept their offer at the next stage if your formal hearing goes worse.

If you have to go to formal ARB

The Appraisal Review Board is the citizen panel that resolves disputed protests. Each county has its own. Hearings are scheduled in May, June, and July. You can appear in person or via videoconference (many counties switched to virtual during 2020-2021 and have kept the option).

A typical ARB hearing follows this format:

1. You introduce yourself and state the property under protest.
2. The CAD presents its appraisal — usually 5 to 10 minutes.
3. You present your evidence — also typically 5 to 10 minutes. You may use the time however you want, but reading your evidence packet aloud is rarely effective. Speak to the key facts. Show the comp table. Point at the single most damning comparable. Be brief.
4. The ARB panel asks questions of both sides.
5. The ARB deliberates (sometimes in your presence, sometimes briefly stepping out) and announces a decision.

You will receive a written determination within a few weeks. If you accept it, the value is set for that tax year. If you reject it, you have options for further appeal — binding arbitration through the State Office of Administrative Hearings (often the most practical for residential properties), or filing suit in state district court (typically only worth it for large commercial properties).

Seven mistakes that lose protests

1. Missing May 15

Already covered. The single most expensive mistake. There is no excuse if your notice arrived on time.

2. Picking the wrong comparables

Comparable selection matters more than almost anything. Common rookie errors:

• Choosing comps that are too far away geographically. Stay within the same Census tract or subdivision when possible.
• Choosing comps with wildly different square footage. ±25% is the upper limit; tighter is better.
• Choosing comps with very different year built. Within ±10 years for most homes; tighter for new construction in established neighborhoods.
• Choosing comps that have very different lot size or amenities. A 1-acre custom build doesn't comp against a 6,000-sqft tract home.

3. Cherry-picking only the lowest comps

If you submit a packet with only the 4 lowest-value homes in a neighborhood, the appraiser knows. They have the same data. Stick to a defensible methodology — every home in the neighborhood within your sqft/year bounds — and use the median, not the bottom.

4. Bringing emotion to the meeting

Anger, frustration, grievance — all understandable, none useful. The appraiser doesn't set policy and can't fix your taxes by themselves. Treat them like the technician they are. State the number, show the data, accept or decline. Save the political energy for taxing-entity rate hearings, where it actually moves the needle.

5. Not requesting the CAD's evidence packet

You have a legal right to see the CAD's evidence under §41.461. Many homeowners never request it. Doing so often reveals weak comps or methodological shortcuts the CAD used — material you can use in your rebuttal.

6. Conceding too quickly at informal review

If the appraiser offers a reduction that's only half what your evidence supports, you do not have to accept it. Formal ARB is intimidating but not adversarial; many homeowners do better there than at informal. The CAD's incentive is to settle quickly; yours should be to settle well.

7. Forgetting about the homestead exemption

If you bought your home in the last 24 months, the homestead exemption may be lapsed. This is a separate issue from your protest but often worth more in dollar terms. Our detailed homestead guide walks through how to check and how to file Form 50-114.

When to pay for help (and when not to)

Property tax protests are not always the right DIY project. Honest assessment:

DIY makes sense when

• You're a residential property owner with a relatively standard home in an established neighborhood
• You have 2 to 4 hours to spend assembling evidence
• Your county has a functional online protest portal
• The dollar value at stake makes a 25% contingency fee feel expensive (which is basically every successful protest)
• You're comfortable speaking up calmly in a 15-minute meeting

Paying for help may make sense when

• You own commercial property — the rules and stakes are different; specialized representation often pays for itself
• Your property has unusual characteristics (custom construction, large acreage, mixed use) where comp selection is genuinely hard
• You are physically or scheduling-constrained from attending hearings
• The dispute is large enough to warrant district-court litigation
• You've been denied a key exemption and the dispute has become legally complex

For 90%+ of Texas residential homeowners, the protest is firmly in the DIY category. The contingency-fee industry exists because the gap between "I have no idea how to do this" and "I have a professional packet in hand" is wide and intimidating. Bridge that gap and you keep the savings.

FAQ

How likely am I to win a property tax protest in Texas?

Aggregate Texas data: roughly 30%-60% of protests result in some reduction, depending on county. Residential homeowners with documented evidence packets do meaningfully better than the base rate — often 60%+. The figures most CADs publish underestimate true success because they include the large number of protests filed with no real evidence.

Will protesting my taxes raise my taxes?

No. The ARB cannot raise your appraised value above what the CAD already proposed in the notice. The worst outcome is no change.

Does protesting damage my relationship with the county?

No. Protesting is a statutory right, exercised by tens of thousands of Texas homeowners every year. CAD staff are not personally offended. They run the same playbook regardless of how you arrived. Many appraisers privately appreciate well-prepared homeowners because the conversation is faster and the evidence is real.

Can I protest every year?

Yes. There is no penalty or limit on annual protests. Many serious property owners protest every year, even years they expect no change.

What if I bought my home below the appraised value?

This is one of the strongest possible cases. A recent arms-length purchase is direct market evidence. Bring your closing disclosure or settlement statement. Texas Tax Code §41.43(a-3) explicitly recognizes this evidence.

Can I appoint my spouse, child, or friend to represent me?

Yes — use Form 50-162 (Appointment of Agent). The agent does not need to be licensed. Family members and trusted friends commonly stand in.

What if I miss the May 15 deadline?

You have no protest right for that tax year. Document everything for next year. Two exceptions: substantial errors in the appraisal record (call your CAD and ask about correction protests), or new construction not previously assessed.

Does the homestead exemption affect my protest?

Directly: no — the exemption affects assessed value, the protest affects appraised value. They are independent. But if your homestead exemption lapsed (often after a recent purchase), restoring it may save you more than the protest. Read this if you bought your home in the last 24 months.
