Texas property tax protest ARB hearing: how to win

Last updated 2026-07-10

What actually happens at a Texas ARB hearing?

The Appraisal Review Board is not a court. It is a panel of three to five local residents, appointed by a local administrative judge, who hear evidence and vote on whether your appraisal district's value is correct. The Texas Property Tax Code, specifically Section 41.66, sets out how hearings run. ^[1]

Most residential hearings last 15 to 30 minutes. The appraisal district representative goes first, presents their evidence, and then you respond. Nobody cross-examines you. Panel members can ask questions, but they tend to be short and practical. The atmosphere is closer to a neighborhood zoning meeting than a courtroom.

Here is the sequence. You check in at the ARB office, usually a room inside the county appraisal district building. The board member acting as chair reads your case number and the district's certified value. The district's appraiser presents an evidence packet, usually comparable sales or a cost-approach summary. You present yours. Both sides rebut briefly. The panel votes, often right there in front of you. Written notice of the decision comes by mail.

That is the whole thing. People psych themselves out expecting something formal. It isn't.

When do you file a protest and what is the deadline?

The standard Texas protest deadline is May 15, or 30 days after your Notice of Appraised Value is mailed, whichever is later. ^[2] That notice comes from your county appraisal district, not from your mortgage servicer or the tax office. Check the mail date carefully, because the 30-day clock starts from the notice date, not the day you open the envelope.

If May 15 lands on a weekend or holiday, the deadline shifts to the next business day. Harris County, Dallas CAD, Bexar County, and every other appraisal district in Texas run under the same statutory deadline, though each keeps its own informal-hearing and ARB schedule that stretches from roughly May through July, and sometimes into September for overflow dockets.

You protest by filing Form 50-132 (Notice of Protest) with your appraisal district. ^[3] Most districts take this online now. You can also walk in and file on paper. The form asks for your grounds: unequal appraisal, value over market value, or both. Check both boxes. It costs nothing extra and keeps both arguments alive.

Miss the deadline and you lose your right to protest for that tax year. No exceptions, no extensions, unless the district mailed your notice after April 15 and you can prove it.

What evidence wins at an ARB hearing?

Two arguments work in Texas: market value and equity (unequal appraisal). Wins almost always come from equity.

Market value means you argue your house is worth less than the certified value. You back this with recent comparable sales, meaning homes similar in size, age, condition, and neighborhood that sold for less per square foot than the district assumed for yours. Recent means within the past 12 months, ideally within 6. Pull these from the MLS if you have access, or from Zillow, Redfin, or Realtor.com, then cross-check against your county's own sales data, which is public.

Equity means you argue your property is appraised at a higher value per square foot (or per unit of comparison) than neighboring properties with the same or better characteristics. Section 41.43 of the Texas Property Tax Code requires the district to appraise your property "in a manner consistent with the appraisals of comparable properties." ^[1] This is the argument that wins most residential protests, because it turns the district's own numbers against it. You pull comparable properties straight from the district's appraisal roll, which is public record on their website.

Here is what to bring, physically, in a packet you hand to each panel member (three copies minimum):

• A one-page summary of your argument and the value you want
• A grid of 5 to 10 comparable properties showing their certified value per square foot next to yours
• Photos of any condition problems (roof damage, foundation cracks, dated systems) with dates
• Repair estimates from licensed contractors
• Your recent purchase contract, if you bought within the past 12 to 24 months for less than the appraised value
• The district's own property detail page for your home, printed, with errors highlighted

A recent appraisal from a licensed Texas appraiser carries real weight but costs money (usually $300 to $600 for a residential property). Use one if you are fighting a large value or a commercial property. For most homeowners, the equity grid stands on its own.

How do you build a comparable sales grid that actually persuades the panel?

The grid is the center of your case. Mess it up and you lose credibility. Get it right and the panel has little room to say no.

Start with your county appraisal district's property search. Look for homes within a half-mile radius, same subdivision if you can, within 200 square feet of your home's size, built within 10 years of yours. Copy their certified values and land values. Then calculate value per square foot: total certified value divided by total living area.

Do this for 8 to 12 properties. If your per-square-foot value sits above the median of the comparable properties, you have an equity case. Present it as a table.

Property	Address	Sq Ft	Cert. Value	Value/SqFt
Subject (yours)	123 Main St	2,100	$420,000	$200.00
Comp 1	118 Oak Ave	2,050	$370,000	$180.49
Comp 2	200 Elm Dr	2,200	$382,000	$173.64
Comp 3	145 Pine Ln	1,980	$346,500	$175.00
Comp 4	301 Birch Ct	2,150	$371,900	$172.98
Median comps				$174.81

Then state your ask: "Applying the median comparable value of $174.81 per square foot to my 2,100 square feet yields a fair value of $367,101. I am asking for a value of $367,000."

That is a specific, defensible, arithmetic request. Panels respond to specificity. Saying "I just think it's too high" gives them nothing to vote on.

For the equity argument you are relying on Section 41.43. You do not need to recite the statute number in the room, but knowing it exists, and mentioning that the district has to appraise consistently, signals you know what you are doing.

What should you say in the hearing, word for word?

You have roughly 10 minutes to present. Use a simple structure and say the numbers out loud.

Opening (30 seconds): "My name is [name], property account number [your CAD account number], located at [address]. I am protesting the certified value of $[X]. I am asking the board to reduce the value to $[Y] based on unequal appraisal under Section 41.43 of the Property Tax Code."

Evidence (6 to 7 minutes): Walk through your grid. Point out that properties in the same neighborhood, same size class, same age range are certified at $174 per square foot, and yours sits at $200. Show the condition photos if you have them. Hand the packets to the panel chair and ask that they be entered into the record.

Close (1 minute): "Based on the district's own certified values for comparable properties, a consistent per-square-foot value applied to my property produces a value of $367,000. I respectfully ask the board to reduce the value to that amount."

Then stop talking. Many people lose at ARB because they ramble, apologize, or say things like "I know you're all volunteers and I appreciate your time." That is fine socially, but it burns your window. Be polite and be brief.

If the district's appraiser presents sales you think are bad comps, rebut by pointing out how they differ: "That sale was a 3,000 square foot home with a pool. Mine has no pool and is 2,100 square feet."

If a panel member asks something you cannot answer, say "I don't have that data in front of me, but based on the comps I've presented, the equity case stands on its own." Do not guess.

What are the most common mistakes that lose ARB hearings?

Showing up with no evidence, or with Zillow screenshots as your only evidence, is the fastest way to lose. The Zestimate is not a reliable indicator of market value, and experienced panelists will say so out loud. Use Zillow as a lead to find actual sales, not as the sale itself.

Asking for an unrealistic value is the second mistake. Ask to drop a $400,000 value to $200,000 with no support and the panel tunes you out. Ask for a value your data actually backs. Panels meet you closer to the middle when your number is grounded.

Bringing condition problems without documentation is a trap. Saying "my house has foundation issues" with no contractor estimate or engineer's report gives the panel nothing to quantify. One estimate on a contractor's letterhead beats five minutes of talking.

Not knowing your own property record is surprisingly common. The district's property detail page lists what they used: bedroom count, bathroom count, square footage, condition grade. If your bedroom count is wrong or your square footage is inflated, that is an automatic adjustment and the easiest win in the building. Pull that page before your hearing and read every line.

Skipping the informal hearing costs you too. Every Texas appraisal district has to offer an informal conference with a district appraiser before your ARB date. ^[2] Many homeowners walk past it. Don't. The appraiser at the informal can settle your case on the spot, often accepting a comp grid just like the one above, and you never sit before the board at all.

How does the informal hearing differ from the ARB hearing, and which one matters more?

The informal hearing is a one-on-one meeting with an appraisal district staff appraiser, not a board panel. It has no formal rules of procedure. You can email evidence ahead of time, show up with your grid, and negotiate. If the appraiser agrees your value is too high, they can issue a written settlement offer that lowers your value without you ever facing the ARB.

The informal is where most reductions happen. According to the Texas Comptroller's protest data, a large share of Texas protests settle at the informal level or get dropped before they ever reach the ARB. ^[4] That makes the ARB hearing the less common ending, not the standard one.

So your play is simple: build the full evidence packet as if you are going to the ARB, then bring it to the informal. If the appraiser offers a fair reduction, take it in writing and you are done. If they offer nothing worth taking, say "I'd like to proceed to the ARB" and you get scheduled. You give up nothing by going through the informal first.

One practical note. The informal appraiser and the ARB panel are different people. What you say to the informal appraiser does not bind the board. You can accept the informal settlement or reject it without prejudice.

What happens after the ARB hearing, and what if you lose?

After the board votes, you get an ARB Order Determining Protest, usually mailed within a few weeks. Win, and the order sets the new certified value, and the district has to honor it for that tax year. Lose, and you still have options.

You can appeal the ARB decision to district court within 60 days of the order being delivered. ^[1] This is where a lawyer usually earns their fee, because district court is real litigation. Most homeowners stop at the ARB level.

Texas also has two cheaper post-ARB paths worth knowing. You can request binding arbitration if your property's appraised value is $5 million or less. ^[5] Arbitration filing fees run $450 to $1,550 depending on property value, and you get the fee back if you win. It is faster and cheaper than district court, usually resolved in 60 to 90 days. The arbitrator's decision is final.

For residential properties valued at $1 million or less where the only issue is unequal appraisal, you can request review by the State Office of Administrative Hearings (SOAH). ^[5] SOAH runs a separate process with lower filing fees.

If you believe the ARB itself acted improperly during your hearing, you can file a complaint with the local administrative judge who appoints board members. This rarely changes your value, but it can matter if there was a procedural violation.

For most homeowners, the math on district court or arbitration comes down to the size of the tax savings. Run the numbers. A $20,000 value reduction at a combined 2.5% tax rate saves $500 a year. Arbitration fees start at $450. That is a close call, and arbitration only makes sense if you are confident in your evidence.

Should you hire a property tax protest firm or do it yourself?

Contingency firms usually charge 25% to 50% of the first year's tax savings, with 30% to 40% common in Texas. ^[6] On $1,000 of annual savings, that is $300 to $400 in fees, every year you win, with no guarantee of effort in any given year.

The honest case for firms: they have volume. A firm handling 10,000 protests knows every appraiser, knows which comparables each district tends to accept, and can often get informal settlements faster than a homeowner walking in cold. For high-value homes, commercial property, or cases involving income approaches, a specialist earns the fee.

The honest case for doing it yourself: the ARB process is built to work without professional representation. The evidence is public. The hearing is informal. The Texas Comptroller publishes a free guide to protesting your appraisal, Publication 96-295. ^[8] If your property is a standard house and your evidence is solid, you can do exactly what a contingency firm would do and keep the entire reduction.

If you want a structured way to organize your evidence, the TaxFightBack DIY Appeal Kit walks you through the comp grid, the equity argument, and the exact packet format, without handing any slice of your savings to a firm.

One thing no contingency firm will tell you: their incentive is to settle fast at the informal for whatever the appraiser offers, since that is where almost all their volume lives. They are not necessarily fighting hard at the ARB on your behalf. If a settlement offer looks low, you have every right to reject it and take it to the ARB yourself.

Do Texas homestead exemptions affect what you protest?

Yes, and the connection matters. Texas homestead exemptions cut your taxable value, but the appraised value the district certifies is separate from that taxable value after exemptions. When you protest, you are fighting the appraised value, which is the ceiling everything else builds on. A lower appraised value cuts your tax bill even when your homestead exemption already takes some off the top.

Texas voters approved Proposition 4 in November 2023, raising the homestead exemption on school district taxes from $40,000 to $100,000 of appraised value, effective for the 2023 tax year. ^[7] Even with the bigger exemption, a lower appraised value reduces taxes from every other taxing unit (city, county, MUD, community college) that may not match that exemption level.

If you do not have a homestead exemption on file, file one before you worry about the protest. The exemption is free, stays in place once filed, and cuts your bill automatically. File with your county appraisal district on Form 50-114. ^[3] The deadline is April 30 of the tax year. Exemptions and protests are separate tracks, and you should run both.

Some counties, including Bexar County, add local exemptions on top of the state rules. Check your district's website for any local freeze or senior exemption you might qualify for.

What are realistic success rates for Texas ARB protests?

Texas is unusual: the Comptroller publishes statewide protest data every year through its Property Value Study. For the 2022 tax year, Texas appraisal districts received roughly 4.2 million protests, and about 1.5 million resulted in value reductions. ^[4] That is around a 36% reduction rate across all protests filed, but that denominator includes the many protests filed and then abandoned or resolved at the informal with no change.

Among protests that actually reached an ARB hearing, the success rate is harder to pin down. The Comptroller's data does not split ARB-only outcomes from informal settlements. Practitioners often estimate that 50% to 65% of prepared, evidence-backed protests get some reduction, but nobody has clean statewide data at that level, so treat that range as informed guesswork, not a published number.

Total value knocked off by protests statewide has run between roughly $30 billion and $60 billion in taxable value per year recently. ^[4] That is real money for Texas property owners in aggregate.

Expect variance by county. Harris County (Houston), Dallas County, and Travis County (Austin) carry very high protest volumes and district appraisers who have seen every trick. Tarrant and Collin counties tend to run less saturated dockets. In every county, the homeowner with clean evidence beats the homeowner with none.

How long does the whole Texas ARB process take?

From filing in May to your final ARB order, expect 2 to 5 months, depending on your county's docket. Harris CAD processes hundreds of thousands of protests, so informal hearings can be scheduled weeks out. Smaller counties may fit you in within days.

The informal hearing usually gets offered within 2 to 6 weeks of your filing. Settle there and you are done. Go to ARB, and your hearing date typically lands in June, July, or August, with the order arriving by mail a few weeks after.

The certified appraisal roll gets finalized by July 25, the statutory deadline for districts to certify values. ^[2] Your tax bill runs off whatever value is certified on that date. If your ARB hearing has not happened by then, your original value gets certified and adjusted after the fact if you win. That is normal and legal. The taxing units that calculate your bill correct it retroactively.

Frequently asked questions

Do I need a lawyer to represent me at a Texas ARB hearing?

No. Texas Property Tax Code Section 41.41 lets any property owner represent themselves at an ARB hearing. You can also use an authorized agent, including a non-attorney, by filing a signed Form 50-162. Lawyers are almost never cost-effective for a standard residential ARB hearing. They make more sense if you appeal to district court after losing at the ARB.

What is the Texas ARB protest deadline for 2025?

The standard deadline is May 15, 2025, or 30 days from the date your Notice of Appraised Value is mailed, whichever is later. Check the notice date closely. If your district mailed notices after April 15, the 30-day window extends past May 15. File online through your county appraisal district's portal, or mail Form 50-132 with a postmark on or before the deadline.

Can I protest my Texas property taxes every year?

Yes. You can file a protest every single year. There is no waiting period and no cap on how many times you protest. If your value drops one year, the district can raise it the next, subject to the 10% homestead appraisal cap. Many Texas homeowners make this an annual routine, especially in high-growth metros where values swing hard year to year.

What is the 10% homestead appraisal cap in Texas and how does it affect my protest?

If you have a homestead exemption, your property's appraised value cannot rise more than 10% per year, regardless of market value. This is separate from your protest. Even if the market supports a 20% jump, the district can only certify a 10% increase on your homestead. The cap does not apply to non-homestead property. It resets when the property sells or the exemption comes off.

How do I find comparable sales for a Texas ARB hearing?

Start with your county appraisal district's online property search to pull certified values per square foot for nearby homes. For actual sales, use Redfin, Zillow, or Realtor.com filtered to the past 12 months, same neighborhood, similar size. Cross-check sale prices against the county's own sales data, which is public record. MLS access through a real estate agent is ideal. Aim for 6 to 10 tight comps within a half-mile radius.

What happens if I miss the Texas property tax protest deadline?

You lose your right to protest for that tax year, with almost no exceptions. Texas courts hold this line hard. The recognized exceptions are for property not on the appraisal roll, clerical errors, or cases where the district failed to send proper notice. Miss it and you focus on filing the following year, and make sure you are set up to catch your Notice of Appraised Value early each spring.

What is the difference between appraised value, assessed value, and taxable value in Texas?

Appraised value is what the district says your property is worth. For most Texas properties, assessed value equals appraised value. Taxable value is appraised value minus any exemptions (homestead, over-65, disability, and so on). Your tax bill is taxable value times the combined tax rate. When you protest, you fight the appraised value, which lowers the ceiling that taxable value builds from.

What is binding arbitration in Texas property tax appeals and is it worth it?

Binding arbitration lets you skip district court after an ARB loss for residential properties valued at $5 million or less. Filing fees run $450 to $1,550. The arbitrator's decision is final, and you get your fee back if you win. It usually resolves in 60 to 90 days, much faster than district court. It is worth it when the potential annual tax savings clear the filing fee by a comfortable margin and your evidence is strong.

How do I request an informal hearing before my ARB date?

When your ARB hearing gets scheduled, you should automatically receive notice of your informal hearing date. If not, call or email your county appraisal district and ask to schedule one. The informal is a required step under Texas law, and every district has to offer it. Come prepared with the same evidence packet you would take to the ARB. Many cases settle here without ever reaching the board.

What if the appraisal district has wrong information about my property, like wrong square footage?

This is the easiest win. Pull the district's property detail page for your account and check every field: living area, bedroom count, bathroom count, condition grade, pool or no pool, year built. If any field is wrong, that is a factual error the district has to correct. Bring documentation: closing papers, a contractor's measurement, or a prior appraisal. Factual errors get fixed at the informal level almost every time, no ARB needed.

Can my property taxes go up after I file a protest?

In theory the ARB can raise your value above the district's certified value if the evidence supports it, but that almost never happens in practice, and Texas law limits the power. Once you file, the district generally cannot push your value above the certified number for that year. The practical risk of a value increase from filing a protest is very low for residential homesteads.

How much does a professional appraisal cost in Texas and do I need one for the ARB?

A residential appraisal from a licensed Texas appraiser usually costs $300 to $600 for a standard single-family home, more for large or complex properties. You do not need one for most ARB hearings. An equity argument built on the district's own comparable certified values is usually enough. A professional appraisal helps most when you recently bought for far less than the certified value, or for high-value or commercial protests.

Is there a fee to file a Texas property tax protest?

No. Filing a protest with your appraisal district is free, and there is no filing fee for the ARB hearing either. Fees only show up if you escalate past the ARB: binding arbitration runs $450 to $1,550, and district court involves attorney and filing costs. The entire ARB protest process, from filing through the hearing, costs nothing but your time.
