The notice arrives in April, the number is higher than last year — again — and everything about the envelope suggests the matter is settled. It isn’t. That number is the appraisal district’s opinion of your property’s value, it was produced by mass appraisal, and Texas law gives you a formal process to challenge it every single year.
Key takeaways
- The Texas property tax protest deadline is May 15, or 30 days after your Notice of Appraised Value was delivered — whichever is later. Filing is free.
- Owners who lose money aren’t the ones who protest badly — they’re the ones who don’t protest at all, or who believe a myth and give up early.
- A Texas property tax protest can escalate through four levels: the informal meeting, the Appraisal Review Board, binding arbitration, State Office of Administrative Hearings (SOAH) or district court, and next year’s cycle.
- Appeal windows after an ARB order run from the date you receive notice of the order, so check your order for exact dates.
- Texas is a non-disclosure state, so a purchase year doesn’t automatically set your assessed value — appraisal districts are guessing at your sale price, and that guess is winnable.
- Texas raised the homestead and business personal property exemptions for 2026, but exemptions are subtracted from your appraised value — an inflated value still costs you.
- What wins a protest is evidence — market comps, an equity analysis, condition documentation — not simply arguing that taxes feel too high.
We’ve been fighting assessed values since 1994, and the pattern never changes: the owners who lose money aren’t the ones who protest badly. They’re the ones who don’t protest at all — or who believe one of the myths below and give up three moves early. This guide is the whole map: the deadline, the myths, every level of appeal, and an honest answer on when to bring in help. If you just want the step-by-step filing walkthrough, we keep that in its own guide: how to protest property taxes in Texas.
The deadline that governs every Texas property tax protest
May 15, or 30 days after your Notice of Appraised Value was delivered — whichever is later. That’s the protest deadline for most Texas property. Your specific date is printed on the notice; treat it as immovable. Miss it and your options shrink to narrow late-protest grounds (good cause, substantial-error provisions), which are real but harder — the ARB decides whether to hear you at all, and generally only up to the point the appraisal records are approved in mid-summer.
File on time and everything in this guide stays available to you. It costs nothing to file.
What changed for the 2026 tax year
In November 2025, Texas voters approved a package of property tax relief amendments. Three matter most here:
- Homestead exemption: the school district homestead exemption rose from $100,000 to $140,000.
- Seniors and disabled owners: the additional exemption for owners 65 and older, or disabled, rose from $10,000 to $60,000.
- Business personal property: the exemption rose from $2,500 to $125,000, starting in 2026, for qualifying tangible personal property used to produce income.
These are real savings, but they don’t replace a protest. An exemption is subtracted from your appraised value, so the value still sets the starting point — and an overstated value still overstates your bill. Check that your appraisal district has applied the exemptions you qualify for, then test the value itself.
Four myths that cost Texas owners real money
We hear all four of these weekly, and every one of them ends the same way — with an owner paying taxes on a value nobody tested.
“All property tax firms are the same.” They aren’t, and the credentialing says why. A Texas property tax consultant registration requires 40 classroom hours of coursework and an exam. A Certified General real estate appraiser credential requires 300 hours of qualifying education, a bachelor’s degree, 3,000 hours of verified appraisal experience, and a national exam. Both are legitimate; they are not the same barrier. We’re appraisers — we fight value with the same discipline used to establish it, and we’ll push your value through every appeal option available, including court.
“Last year’s value is the floor.” It isn’t, in any negotiation. We see it time and time again: values reduced below the prior year, because the owner handled the protest alone the year before, or the previous representative didn’t do enough due diligence on the property.
“I just bought it, so my purchase price is the value.” Texas is a non-disclosure state — appraisal districts are not privy to commercial sale prices. They guess. Sometimes the guess is high, and owners assume a purchase year is a dead year. It isn’t, and the proof is below.
“Protesting will make them raise my value later.” The protest process tests the district’s evidence for this year. Values are set annually regardless of whether you protested. Not protesting doesn’t buy goodwill; it buys an untested number.
A purchase-year case, with the actual numbers
A client bought a large shopping center south of Houston for $90 million. The appraisal district — guessing, as districts do in a non-disclosure state — took the assessment from $60 million to $95 million in the purchase year. Even disclosing the closing statement would only have argued the value down to $90 million, unacceptable to the owner and to every tenant whose leases would absorb the increase.
We took it through the administrative process without disclosing the closing statement, then filed suit. A year later, through negotiation and attorney work, the value came back at $62 million. In a purchase year, that is very, very hard to do — and it’s why “the process” in this guide doesn’t stop at the hearing room.
The four levels of a Texas property tax protest
Level 1 — The informal. Before any formal hearing, most districts will meet with you — often by phone or online — and many protests settle right here. You review the district’s evidence, present yours, and an appraiser at the district can agree to an adjustment. Fast when it works — but never accept a number just because the meeting was pleasant. Know your walk-away value before it starts.
Level 2 — The Appraisal Review Board. A panel of citizens, independent of the district’s appraisal staff, hears both sides in a structured hearing: the district presents its evidence, you present yours (market comps, an equity analysis against comparable properties’ assessments, condition documentation, income data for commercial property). You can choose to appear in person, by telephone, or by videoconference. The ARB rules, and its order sets your value — unless you escalate. What wins here is evidence, not indignation. The ARB hears “my taxes are too high” all day; it can only act on “my value is wrong, and here’s why.”
Level 3 — Binding arbitration, SOAH, or district court. An ARB order isn’t the end, but the clock starts when you receive notice of it. Each route has its own filing window, so check your ARB order and the Tax Code for your exact dates:
- Binding arbitration is a faster, cheaper alternative to litigation. An independent arbitrator decides, and the decision binds the district. Your deposit is refunded, less a small administrative fee, if the arbitrator’s value lands closer to your opinion than to the ARB’s.
- SOAH (the State Office of Administrative Hearings) hears value disputes on non-industrial property valued above $1 million. Notice of appeal is due within 30 days of receiving the ARB’s decision.
- District court is the full remedy. For larger and commercial matters, it’s where the $90 million case above was won.
Level 4 — Next year. Values reset annually, and so does the process. The evidence file you built this year is the head start on the next one. Owners who treat this as an annual discipline — the way they treat insurance renewals — are better positioned to hold their values down than owners who protest once and coast.
What to do right now, outside protest season
- Received an ARB order this summer? Check your Level 3 deadline today. The window runs from the date you received notice of the order.
- Missed the 2026 deadline? Late-protest grounds are narrow, and the window generally closes once the appraisal records are approved. Plan for 2027 instead.
- Preparing for 2027? January through March is the best time to build the evidence file — sales comps, income and expense data, condition documentation — well before notices arrive in April.
Doing it yourself vs. bringing a property tax consultant
Honest answer: plenty of homeowners handle a straightforward residential protest themselves, and our step-by-step guide plus our property tax calculator exist so you can. If your evidence is clean and the number at stake is modest, do it yourself first.
Where representation earns its fee:
- Commercial property, where income approaches, equity analyses, and six- or seven-figure swings are in play
- Purchase years, where strategy around what you disclose — and when — matters enormously (see above)
- Post-ARB escalation — arbitration and litigation are process-heavy, and the district’s side does this every day
- Portfolios, where hearing season means dozens of files compressed into a few summer months. Availability matters here: we staff for the season, we hand out cell numbers, and we answer client emails the same business day.
What we bring beyond the 40-hour registration standard: we’re appraisers first. One important distinction, though, because it’s central to how we work: when we appraise, we’re independent and advocate for no one — that’s the profession’s ethical line. When we consult on your protest, we advocate hard for you, using that same valuation expertise as the tool. Two different assignments, never blurred.
What it costs you to do nothing
Texas has no state income tax; property tax is the bill that matters here, and it compounds. An untested value becomes next year’s starting point, and the appeal you didn’t file becomes equity you gave away annually. For commercial owners with triple-net leases, an inflated assessment isn’t even your cost alone — your tenants absorb it, and they remember who let it happen.
Frequently asked questions
Is it worth protesting your property taxes every year? Usually, yes — filing is free, values reset annually, and the district’s evidence changes year to year. At minimum, review the notice against your own evidence every April. The years you skip are the years the number moves unchecked.
Can my value go UP because I protested? The ARB decides what the evidence supports, so an increase is possible if the district’s evidence is stronger than yours. That’s the reason to review your evidence before the hearing, not during it — a consultant will flag that risk up front.
I just bought the property — is the purchase price now my value? Not automatically, in either direction. Texas districts don’t see commercial sale prices; they estimate. If the assessment jumped past your purchase price, that’s winnable. If you paid more than the assessment, disclosure strategy matters — get advice before you hand anyone your closing statement.
The new exemptions lowered my bill. Do I still need to protest? If your appraised value is too high, yes. Exemptions are subtracted from the appraised value, so a lower value reduces what’s left to tax. Check that your exemptions were applied, then test the value.
What does a property tax consultant actually do that I can’t? Evidence, mostly: market and equity analyses built with appraisal-grade tools and data, hearing experience with your specific district, and the judgment about when to settle, when to go to the ARB, and when to escalate to arbitration, SOAH, or court. On a modest residential file you may not need that. On a commercial file, the fee typically argues for itself.
Every question above has a longer answer specific to your property, and there’s no such thing as a dumb one — most owners do this once a year at most; we do it every day of the season. Talk to our team, and bring the notice.
