A family that owns a leased warehouse in Brownsville receives its notice of appraised value in the spring. The value is higher than last year. The family member who handles the property lives in Matamoros, the notice went to an old mailing address, and by the time anyone reads it, the protest deadline has passed. The tenant, who reimburses the taxes under a net lease, asks in the fall why nobody protested. The building did not change. The calendar did.
This article is an owner brief on the Texas property tax protest and appeal process for owners and investors holding industrial, flex, warehouse, yard, or small commercial property in Brownsville and Cameron County. It is not legal, tax, or appraisal advice. The full cost of holding a property lives in ownership costs. Abatements and the Freeport exemption live in tax abatements and incentives. Agricultural special appraisal and rollback tax live in agricultural valuation. This page owns the yearly cycle for challenging an appraisal: the valuation date, renditions, the notice, the protest deadline, evidence, the Appraisal Review Board hearing, and the appeal options after it.
Alfredo Cristo Realty Group works from Brownsville with more than 45 years of advisory and stewardship experience, Texas real-estate licensing, and a background in Mexico corporate and real-estate law. The objective matches our promise: Experience that protects your investment. Education first. Specialist handoff when the question leaves the real-estate lane.
What is the deadline to protest a property appraisal in Texas? Texas Tax Code Section 41.44 says the property owner must file a written notice of protest with the appraisal review board not later than May 15 or the 30th day after the notice of appraised value was delivered, whichever is later. The Texas Comptroller's protest page adds that the 30 days run from the date the appraisal district mails the notice. A late protest may still be heard if the owner shows good cause before the board approves the appraisal records.
Can a tenant protest the appraisal of a building it leases? The Texas Comptroller explains that a lessee whose lease requires it to pay the owner's property taxes may protest the property's value to the appraisal review board, but only if the owner does not. The right applies to leased land, buildings, and personal property. The owner of leased real property must send the tenant a copy of the notice of appraised value, and the tenant may ask the chief appraiser to send the notice directly to it.
This article is educational only. It is not legal, tax, appraisal, or investment advice. Retain a property tax consultant or Texas tax counsel, a CPA, and, where a value opinion is needed, a certified appraiser for those decisions. Nothing below estimates any property's value, tax rate, tax bill, or the outcome of a protest. Statutory statements are attributed to the Texas Tax Code sections they come from, and process statements to the Texas Comptroller and the Cameron Appraisal District pages listed under Sources.
Why this matters for Cameron County owners now
Three things make the coming year worth planning for in November:
- 2026 tax bills are arriving. Texas Tax Code Section 31.02 says taxes are due on receipt of the bill and become delinquent if not paid before February 1 of the following year. That date also matters for appeals, as explained below.
- The circuit breaker limitation ends. The Texas Comptroller states that the circuit breaker limitation in Tax Code Section 23.231, which caps yearly increases in the appraised value of qualifying non-homestead real property at 20 percent plus new improvements, expires December 31, 2026. The Comptroller lists the 2026 eligibility ceiling as $5,320,000 of value. Owners whose notices showed both a market value and a lower capped value should expect the 2027 notice to be read without that cap unless the law changes.
- Business personal property rules changed in 2026. The Comptroller's 2026 rendition form, Form 50-144, describes an exemption of $125,000 of appraised value for income-producing tangible personal property under Tax Code Section 11.145, and an election not to render when the owner certifies that the property's value is not more than $125,000.
None of this tells you what your property is worth. It tells you that the 2027 cycle starts on January 1 and rewards the owner who is organized before the notice arrives.
Who does what in Cameron County
Owners often call the wrong office. The roles are separate:
- Cameron Appraisal District (CAD): appraises property and sends notices of appraised value. Its website states that it does not collect taxes or have tax amounts and directs owners to the tax office for tax questions
- Appraisal Review Board (ARB): hears protests. The Cameron Appraisal District describes the ARB as a separate body whose members are not CAD employees and are appointed by the CAD board of directors for two-year terms
- Tax assessor-collectors: bill and collect taxes for the taxing units
- Taxing units: set the tax rates. The CAD's tax office list for Cameron County includes, among others, Cameron County, the City of Brownsville, Brownsville I.S.D., the Brownsville Navigation District, Texas Southmost College District, and county drainage districts
Tax Code Section 25.19 requires the notice of appraised value to say, in italic type, that the Texas Legislature does not set the amount of local taxes and that the tax burden is decided by locally elected officials. A protest addresses the value and the appraisal records. It does not address the tax rate.
The yearly calendar
January 1: the valuation date and the rendition
Tax Code Section 23.01 says taxable property is appraised at its market value as of January 1. For a warehouse, that means the condition of the roof, the vacancy of the building, and the state of the yard on January 1 are what count for that year. Photographs and repair estimates dated near January 1 are useful later.
Tax Code Section 22.01 requires a person to render tangible personal property used for the production of income that the person owns or manages and controls as a fiduciary on January 1—equipment, furniture and fixtures, machinery, and inventory. Section 22.23 sets the filing window after January 1 and not later than April 15, and says the chief appraiser must extend the deadline to May 15 on written request. Section 22.28 imposes a penalty equal to 10 percent of the taxes on the property for failing to file a required rendition on time.
Two points owners of real estate tend to miss:
- Real property renditions are optional unless the chief appraiser requires one, under Section 22.01(b) and (c), but a building owner who also owns equipment in the building has a business personal property obligation
- Rendition affects the protest. Tax Code Section 41.43(d) says that if the owner fails to deliver a required rendition statement or property report before the hearing, the owner has the burden of establishing value by a preponderance of the evidence
The Comptroller's April 2026 rendition reminder also notes that owners whose property was damaged by storm, flood, or fire in the prior calendar year may file a special decreased value report showing the property's condition on January 1. In the Lower Rio Grande Valley, that belongs on the storm checklist described in our flood, stormwater, and windstorm brief.
Spring: the notice of appraised value
Tax Code Section 25.19 says the chief appraiser must deliver a notice of appraised value by May 1, or as soon thereafter as practicable, for property other than a residence homestead when, among other triggers, the appraised value is greater than the year before, greater than the value the owner rendered, or the property was not on the roll the year before. The notice separates real and personal property, lists the taxing units, shows the prior and current values, and explains how and when to protest.
The notice goes to the owner of record at the address the appraisal district has. Section 1.111(f) lets an owner direct, in writing filed with the appraisal district, that notices, tax bills, and orders for specified property be delivered to a named person instead. The Cameron Appraisal District also accepts Form 50-843 requests for electronic communications through its public portal.
May 15 or 30 days: filing the protest
Section 41.41 lists what an owner may protest, including the appraised value, unequal appraisal, the inclusion of the property on the records, the denial of a partial exemption, and any other action of the chief appraiser or board that adversely affects the owner. Section 41.41(d) says no fee may be charged to file a protest.
The Comptroller's Form 50-132, Property Owner's Notice of Protest, is the standard filing, but the Comptroller notes that a notice is sufficient if it identifies the property, the owner, and the dissatisfaction in writing. The Comptroller also describes an informal conference with appraisal district staff before the formal hearing, where many protests are discussed first.
Building the evidence file
What the appraisal district must give you
Section 41.461 says that at least 14 days before the hearing the chief appraiser must deliver the Comptroller's taxpayer assistance pamphlet and the ARB hearing procedures, and inform the owner that the owner or agent may request a copy of the data, schedules, formulas, and other information the chief appraiser will introduce at the hearing. Copies are free.
Ask for that information as soon as the protest is filed. Section 41.67(d) says information the owner requested under Section 41.461 that was not delivered at least 14 days before the hearing may not be used as evidence at the hearing, except to rebut the owner's evidence.
Market value or unequal appraisal
An owner can protest on two different value grounds, and they call for different evidence:
- Market value (Section 41.41(a)(1)): the argument that the appraisal is higher than what the property would sell for as of January 1. The Comptroller's valuation page describes three common approaches—sales comparison, income, and cost—and says the income approach is most suitable for property frequently bought and held to produce income
- Unequal appraisal (Section 41.41(a)(2)): the argument that the property is appraised at a higher level than comparable properties. Section 41.43(b) says the protest is decided for the owner unless the appraisal district establishes one of the comparisons the statute lists, including that the appraised value is equal to or less than the median appraised value of a reasonable number of comparable properties appropriately adjusted
Section 41.43(a) generally places the burden on the appraisal district to establish value by a preponderance of the evidence in either type of protest. Section 41.43(a-3) raises that to clear and convincing evidence when the value was lowered in the preceding year (other than by a written agreement under Section 1.111(e)) and the owner files the required income, sales, or equity information at least 14 days before the hearing. Section 23.01(e) also limits increases in the year after a value is lowered unless supported by clear and convincing evidence.
Evidence for income-producing industrial property
Section 23.012 says that when the income method is the most appropriate, the chief appraiser analyzes comparable rental data, operating expense data, and capitalization or discount rates, and bases projections on reasonably clear and appropriate evidence. That makes the owner's own records relevant. The Comptroller's protest page lists the kinds of evidence owners bring, including photographs, repair receipts or estimates, sales documentation such as closing statements, engineering reports, surveys, and deed records. For leased industrial and commercial buildings, owners and their consultants also commonly assemble:
- The rent roll and leases in effect on January 1, including vacancy and concessions, as described in our leased-building buyer brief
- Operating statements for the prior years and expense reimbursements actually collected
- Condition evidence: roof, slab, paving, drainage, fire protection, and deferred maintenance with dated estimates
- Functional limits: clear height, loading, truck court depth, power, and water, which our power and water capacity brief explains
- A recent appraisal, if one exists. Section 41.43(a-1) gives special weight to a qualifying appraisal by a Texas-certified appraiser for property valued at $1 million or less, if it is filed and delivered at least 14 days before the hearing and meets the statute's attestation requirements
We do not offer typical rents, capitalization rates, or expense ratios for Brownsville property, because we do not have a public source for them that applies to any particular building.
The hearing
The Cameron Appraisal District's ARB page states that the board begins protest hearings in early May and typically finishes by the end of July, though it may continue hearing a substantial number of protests through September, and that hearings are held at the CAD office. The Comptroller explains that an owner may appear in person, by telephone or videoconference, or by written affidavit, and that the hearing notice and procedures may set rules for copies of evidence.
Points that matter in practice:
- The board decides by written order. Section 41.47(c-2) says the board may not set the value above the value in the appraisal records submitted to it, except as requested and agreed to by the owner
- Stay on value. The Comptroller notes that the ARB cannot consider the owner's personal economic situation and that neither the ARB nor the appraisal district sets taxes
- One year at a time. The Comptroller and the Cameron Appraisal District both state that ARB decisions are binding only for the year in question
- Agreements are final. Section 1.111(e) says an agreement between the owner or agent and the chief appraiser on a protestable matter is final
After the ARB: appeal options
If the owner disagrees with the ARB order, the Comptroller describes these paths. Each has its own eligibility rules and deadlines, so the choice belongs with a tax consultant or counsel:
- District court: a petition for review must be filed within 60 days of receiving the ARB's written order. Section 42.08 says the owner must pay, before the delinquency date, the lesser of the taxes on the undisputed value, the taxes under the ARB order, or the prior year's taxes, or forfeit the right to a final determination, unless a court excuses prepayment after an oath of inability to pay
- Regular binding arbitration: available for value or unequal appraisal determinations when the ARB-determined value is $5 million or less (no limit for residence homesteads). The request and deposit go to the Comptroller within 60 days of receiving the order; Section 41A.03 sets the deposit by value. The Comptroller's arbitration page also requires that taxes have been timely paid and that no district court lawsuit has been filed on the same matter, and says arbitrators must dismiss requests that do not meet the law's requirements
- State Office of Administrative Hearings (SOAH): for ARB-determined values over $1 million on value or unequal appraisal questions. The Comptroller states that this option does not apply to industrial property and requires a notice of appeal within 30 days and a deposit
- Limited binding arbitration: a separate Comptroller process under Section 41A.015 to compel the ARB or chief appraiser to follow procedural requirements, such as following its hearing procedures, scheduling a hearing, or delivering required hearing materials at least 14 days before the hearing
A 2026 change for tenants
House Bill 1533 (89th Legislature) added Section 41A.011, which allows a lessee contractually obligated to reimburse the owner's taxes to appeal certain ARB value orders through binding arbitration for requests filed on or after January 1, 2026, subject to the $5 million limit. Under that section, the protest must have been brought by the tenant itself, or by the owner if the owner does not appeal the order.
Leases, tenants, and who protests
On net leases, the tenant often pays the tax bill indirectly, which makes the protest a lease question as well as a tax question. Points to settle in the lease and in practice:
- Who decides whether to protest, who pays the consultant, and how any refund or credit is shared
- Who receives the notice of appraised value and by what date it is forwarded to the tenant
- Whether the tenant may protest if the owner does not, and how the owner and tenant share information for the hearing
- How a pending protest is handled at a sale; see our leased-building buyer brief
Our landlord leasing guide covers reimbursement clauses more broadly.
Agents, mail, and owners who live elsewhere
Section 1.111 lets an owner designate an agent for property tax matters on the Comptroller's Form 50-162, Appointment of Agent for Property Tax Matters. The designation takes effect when filed with the appraisal district, stays in effect until revoked or until it expires by its own terms, and an owner may not designate more than one agent for the same item of property.
For Mexican and binational owners, the practical risk is usually not the law but the mail. Practical steps:
- Confirm the mailing address and the owner name on the appraisal records match the deed and the owning entity; see binational capital
- Decide in writing who in Texas receives and logs appraisal notices, tax bills, and ARB orders
- Calendar January 1, April 15, May 1, May 15, and February 1 every year
- Keep the decision to protest, settle, or appeal with the owner, even when an agent files the paperwork
Families holding inherited property face the same calendar with more signers; see inherited family land.
Special situations to flag
- Agricultural or open-space land: a change-of-use determination has its own 30-day protest rule under Section 41.44(a)(3); see agricultural valuation
- Abatements and Freeport: exemption filings follow their own deadlines; the Cameron Appraisal District FAQ lists tax abatements and Freeport goods among exemptions that require an annual application by April 30; see tax abatements and incentives
- New construction and additions: the Comptroller's circuit breaker explanation separates new improvements, which increase market value and are added on top of the capped amount, from repairs and ordinary maintenance, which are not new improvements; see ground-up development
- Storm damage: see the decreased value report noted above and our flood, stormwater, and windstorm brief
Documents folder for the yearly appraisal cycle
- Appraisal account numbers for land, improvements, and business personal property
- Prior notices of appraised value, ARB orders, and any settlement agreements
- Business personal property renditions and filing confirmations
- January 1 photographs and condition notes

- Repair estimates, inspection reports, and engineering reports
- Closing statement and appraisal from the purchase, if recent

Common mistakes owners make
- Reading the notice after the deadline because it went to an outdated address
- Calling the appraisal district about the tax rate, which it does not set
- Skipping the rendition and then carrying the burden of proof at the hearing
- Not requesting the appraisal district's evidence early enough to review it
- Arguing the tax bill instead of the value
- Missing the February 1 payment requirement while an appeal is pending
- Leaving the tenant out when the lease shifts taxes to the tenant
- Assuming the 20 percent cap continues in 2027 without checking the law
Questions to bring to your tax consultant, CPA, or counsel
- Should this property be protested on market value, unequal appraisal, or both?
- What evidence do we have as of January 1, and what should we request from the appraisal district?
- Does the property need a business personal property rendition, and do we qualify for the $125,000 exemption election?
- If the ARB order is not acceptable, which appeal path is available, and what must be paid before February 1?
- How does the end of the circuit breaker limitation affect this property's 2027 notice?
- What does the lease say about protests, consultant fees, and refunds?
