What to Do When You Receive Your Appraisal Notice

Every spring, more than five million Notice of Appraised Value forms hit Texas mailboxes between mid-April and early May. For commercial owners, that single envelope sets the tax base for the entire year — and most of the time the proposed value is higher than it should be. Across the state, appraisal districts publish reappraisal plans projecting double-digit value increases on commercial classes in major metros, while sales volume on the same property types has slowed sharply over the last two cycles. The result is a structural mismatch: mass-appraised values are climbing while transactional evidence is flat or declining.

This is a data-first guide for owners who just opened the envelope. It walks through what the numbers on your notice actually mean, which lines deserve scrutiny, and the exact sequence of decisions that have to be made — usually inside a 30-day window — to protect your tax base for the year.

The Numbers Behind Your Texas Appraisal Notice This Year

Texas has roughly 254 county appraisal districts (CADs), each producing notices for every taxable parcel in their jurisdiction. Commercial reappraisal cycles vary, but most CADs reassess commercial real property every year under their state-approved reappraisal plan. Statewide data from the Texas Comptroller and Texas Taxpayers and Research Association consistently shows commercial appraisal increases outpacing residential ones, particularly in office, retail, and multi-tenant industrial classes.

A few patterns repeat almost every year. Mass appraisal software applies a market adjustment factor to entire neighborhoods or commercial zones at once, which means properties with weak operating performance get pulled up alongside the strongest performers in their cohort. Older buildings often see depreciation under-applied because the cost approach is recalibrated to current construction prices, not to the property’s actual age and condition. Tenant rollover, deferred maintenance, and concessions rarely make it into the CAD’s data set unless the owner provides them. The cumulative effect is that the typical commercial notice arrives carrying value assumptions that the property could not actually sell for on January 1 of the tax year — which is the legal standard under Texas Tax Code §23.01.

Owners often assume their notice reflects an appraiser walking the property. In reality, most commercial properties in Texas are valued through computer-assisted mass appraisal models that consume CoStar-style market data, building characteristic files, and prior-year roll values. A single appraiser may be responsible for thousands of accounts. That structure is why protest activity is so consistently effective: it forces a human review using property-specific evidence that the mass model never saw.

What Your Notice of Appraised Value Actually Contains

A standard Texas Notice of Appraised Value (the form your CAD sends in April or May) contains several distinct numbers that owners commonly conflate. Reading them in the right order is the first step in any informed response.

The “Total Appraised Value” is the CAD’s estimate of market value for your parcel as of January 1. For commercial property, this is the number that protest evidence is built around. The “Assessed Value” may differ from the appraised value if a special valuation or cap applies, such as the 20% appraisal cap on certain non-homestead real properties enacted in 2023 and effective for tax years beginning in 2024. The “Taxable Value” subtracts any exemptions before tax rates are applied.

The notice also lists each taxing unit — county, city, school district, hospital district, community college, MUDs, and others — and shows last year’s adopted rate alongside the current year’s “no-new-revenue” and “voter-approval” rate calculations. The estimated tax column gives a forecast of what the year’s bill will look like if you do nothing. That column is the single most useful psychological data point in the entire notice: it converts an abstract appraisal value into a concrete dollar consequence.

Finally, the notice carries a protest deadline date. In most counties, this is 30 days after the notice was mailed, or May 15, whichever is later. The deadline is governed by Texas Tax Code §41.44, and missing it forfeits your right to a formal protest for the year except in narrow good-cause circumstances. The deadline printed on your specific notice always controls — counties mail in waves, and the date on a neighbor’s notice may differ from yours by a week or more.

The 30-Day Window That Decides Your Tax Year

The protest window is short by design. Appraisal Review Boards (ARBs) work backward from a July 25 certification deadline for most CADs, which is when the appraisal roll is finalized and handed to the assessor-collector for billing. Every protest filed has to be heard, decided, and posted to the roll before that certification, which is why filing windows compress into roughly six weeks of intense scheduling.

The asymmetry of this window matters. The CAD spends roughly nine months building the mass appraisal model. The owner gets thirty days to assemble counter-evidence, decide whether to protest, file the right form, and prepare for either an informal conference or a formal ARB hearing. Owners who treat the notice as a “deal with it later” document routinely lose the year, because the deadline is statutory and ARBs rarely accept late filings.

Practically, the 30-day window divides into three phases. Days 1 through 7 should be spent reading the notice carefully and pulling supporting documents. Days 7 through 21 are for evidence assembly — rent rolls, operating statements, recent comparable sales, photos of any deferred maintenance or vacancy, and any third-party reports. Days 21 through 30 are for filing Form 50-132 and requesting any required evidence exchange from the CAD under Texas Tax Code §41.461. Owners who compress this sequence into the last 48 hours almost always file a thinner protest than the property deserves.

Reading Your Notice Like an Appraiser Would

Commercial owners get more value from their notice when they read it the way a CAD reviewer would on the other side of a hearing. Three numbers deserve specific attention.

First, the year-over-year change. If the appraised value jumped more than 10% from the prior year, the CAD applied either a market adjustment factor specific to your neighborhood or a property characteristic change in their records. Both are challengeable. If the jump exceeds 20% on real property, the 2023 appraisal cap should have limited it for non-homestead properties — and if it didn’t, that’s an immediate procedural issue worth flagging.

Second, the value per square foot. Divide the total appraised value by your building’s improved square footage. Compare that number against recent transactions for similar property types in your submarket. If your $/SF appraised value sits at or above the top of the recent transaction range, the CAD is implicitly projecting an above-market sale price for your parcel. That gap is where protest evidence lives.

Third, the implied capitalization rate. For income-producing commercial property, divide stabilized net operating income by the appraised value. If the resulting cap rate is materially lower than what your submarket is actually trading at — say, 5.5% appraised against an 8% trading market — the CAD’s income approach is using stale or aggressive assumptions. This is one of the strongest evidence points available under Texas Tax Code §23.012, which governs the income approach for income-producing property.

When the Numbers Signal a Likely Overassessment

Not every appraisal notice warrants a protest. A clear-headed read of the numbers usually sorts properties into one of three buckets: clearly overassessed, ambiguous, and arguably fair.

Clearly overassessed properties typically share several traits. The year-over-year value increase is above the local commercial reappraisal trend. The implied $/SF or cap rate is misaligned with recent market activity. The property has known physical or economic issues — vacancy above the market average, deferred maintenance, environmental constraints, tenant credit deterioration — that the CAD data set wouldn’t have captured. In this bucket, protest math is strongly favorable: even a 10% to 20% reduction can return thousands in annual tax savings, and the savings repeat for the life of the lower base if the next year’s mass model anchors to it.

Ambiguous properties show smaller increases, in-line $/SF, and no obvious red flags. These still merit a protest filing as a procedural defense — a filed protest preserves your right to negotiate informally, exchange evidence, and receive a hearing. Many of these properties end up settling at a modest reduction during the informal phase without ever reaching the ARB.

Arguably fair properties show value movement consistent with verifiable market activity and no property-specific issues. Even here, owners commonly file a protest to test whether the CAD will accept a small reduction in exchange for closing the file early. The downside is procedural cost; the upside is occasional small wins.

The general rule for Texas commercial property: if the notice arrived with any year-over-year increase, the math almost always favors filing. The marginal cost of preparing a basic protest is low compared with the multi-year impact of an inflated base.

The Decision Tree: Protest, Accept, or Negotiate Informally

After reading the notice, three paths exist. Each carries a different procedural and financial profile.

Accepting the notice is the default if no action is taken. The value certifies as proposed and the tax bill calculates from there in October. This path is appropriate only when the owner has carefully verified that the CAD’s number reflects an honest market value for the January 1 date — which is rarer than most owners assume.

Informal negotiation is available in nearly every Texas CAD. Owners or their representatives can request an informal meeting with a staff appraiser before any ARB hearing. The CAD reviews the evidence presented and may offer a reduction on the spot. Texas Tax Code does not require an informal phase, but in practice it resolves the majority of commercial protests filed each year. Informal resolution requires that a protest be filed by the deadline; the conference itself happens after the filing. Many owners are surprised to learn that “just calling the CAD” without filing has no procedural standing — the protest filing is what unlocks the negotiation.

Formal protest pushes the case to the ARB if informal negotiation fails to produce a satisfactory offer. The ARB is a panel of citizens trained in Texas Tax Code procedures, and hearings follow rules set out under Texas Tax Code §41.66. Evidence exchange rules under §41.461 require the CAD to share its evidence on request at least 14 days before the hearing, which gives the owner time to prepare rebuttals. ARB decisions can be appealed to district court, binding arbitration, or the State Office of Administrative Hearings depending on property value and case posture, though the vast majority of commercial protests resolve at or before the ARB.

The decision among these three is rarely close once the numbers are run. Filing preserves every option. Not filing forecloses all of them.

Filing a Texas Form 50-132 the Right Way

The standard protest form is the Comptroller’s Form 50-132, “Notice of Protest.” It is short — usually two pages — but the choices on it shape the entire case. Owners frequently file Form 50-132 incorrectly and limit their own arguments before the hearing even begins.

The form lists several protest grounds. The two most commonly used for commercial property are “Value is over market value” under Texas Tax Code §41.41(a)(1) and “Value is unequal compared with other properties” under §41.41(a)(2). Both should generally be checked. Market value protests use evidence specific to the subject property — comparable sales, income approach, cost approach. Equal-and-uniform protests use a statutory median calculation across a comparable property group. They are independent legal theories, and the ARB can grant relief on either. Checking only one ground forfeits the other for the year on that protest.

Other grounds — “Property should not be taxed in this appraisal district,” “Property is exempt,” “Owner’s name is incorrect,” “Property description is incorrect” — apply in narrower circumstances and should be added when the underlying facts warrant. The filing should specify a target opinion of value to ground the conversation, though Texas does not require a specific number to be stated on the form itself.

The form must be filed by the deadline printed on the notice. Most CADs accept electronic filings through their property search portal, and Texas Tax Code §41.44(d) treats a timely-mailed protest as filed on the postmark date. Filing in person at the CAD office is also valid. Filings sent by email outside the formal portal are accepted by some CADs and rejected by others — owners should not rely on email unless they have explicit confirmation from the specific CAD that email constitutes a valid filing.

What Happens After You File Your Protest

Once Form 50-132 is on file, the CAD acknowledges receipt and the case enters the queue. The sequence from that point follows a predictable pattern in most counties.

Within several weeks of filing, the CAD typically reaches out to schedule an informal review. The owner or representative presents evidence — rent rolls, operating statements, photos, third-party reports, comparable sales, equal-and-uniform analysis. The staff appraiser reviews the file and either offers a reduction, holds the value, or proposes a counter-number. If the offer is acceptable, the case is closed by signing a settlement agreement and the new value is certified.

If informal negotiation does not resolve the case, the matter proceeds to the ARB. The ARB hearing is scheduled with advance notice under §41.46. Either side can request evidence exchange under §41.461 to see what the other intends to present. Hearings typically run 15 to 30 minutes for routine commercial cases and longer for complex properties. The panel deliberates, votes, and issues an order determining protest under §41.47 within a short period after the hearing.

If the ARB decision is unsatisfactory, the owner has options for further appeal. Texas Tax Code §42.01 allows judicial review by petitioning district court within 60 days of receiving the ARB order. Binding arbitration is available under Chapter 41A for properties under specific value thresholds with a smaller fee. Properties valued above $1 million can elect appeal through the State Office of Administrative Hearings under Chapter 41B. Each path has its own procedural rules and cost structures.

Most commercial protests do not reach appeal. The combination of evidence-exchange transparency and the ARB’s interest in clearing the docket means that informed, well-prepared protests are typically resolved before or at the ARB.

How a Contingency-Based Representative Changes the Math

Many Texas commercial owners weigh whether to handle the protest themselves or engage a representative. The decision usually comes down to time, evidence quality, and economic alignment.

A typical commercial protest, done well, requires roughly 8 to 25 hours of preparation depending on property complexity. That covers reading the notice, pulling and organizing rent rolls and financials, building a comparable sales set, running an equal-and-uniform analysis, requesting and reviewing the CAD’s evidence packet, attending the informal review, and (if needed) presenting at the ARB hearing. For owners running an active business, that hour count is real.

Contingency-based representation aligns the economics directly. The representative is paid only out of first-year tax savings — typically 30% to 50% across the Texas market — meaning the owner pays nothing if the value is not reduced. This is the model LowerMyCommercialTax.com uses: 30% of first-year savings, with no flat fees, retainer, or upfront cost. The owner keeps the multi-year benefit of the lower base in subsequent years, since the second-year and beyond savings are not subject to the contingency.

The case for representation strengthens with property complexity, geographic spread, and number of accounts. A single warehouse may be efficient to protest in-house. A portfolio of mixed-use properties across multiple counties is rarely worth the in-house time, and the evidence specialization of a dedicated representative typically yields larger reductions than the owner would secure alone.
