The Complete Texas Commercial Property Tax Protest Process: Filing to Resolution

Most Texas commercial property owners know they can protest their appraisal. Most have no idea how the process actually works — what to file, when to file it, what evidence matters, and what happens at each stage. The result is either no protest at all, or a poorly prepared one that gets a token reduction and leaves significant savings on the table.

This guide covers the complete Texas commercial property tax protest process from start to finish: every step, every deadline, every decision point, and the evidence strategy that produces real reductions.

The Foundation: Understanding What You’re Protesting

Before you file anything, you need to understand exactly what you’re challenging. Texas property tax is based on the appraisal district’s opinion of your property’s market value as of January 1 each year. Your protest argues that this opinion is wrong — specifically, that the appraised value exceeds actual market value, or that your property was appraised unequally compared to similar properties.

Texas Tax Code §41.41 defines the grounds for protest. The two most relevant for commercial property owners are:

Market value protest (§41.41(a)(1)): The appraisal district’s value exceeds the property’s actual market value. This is the most common commercial protest ground and the one requiring the strongest evidence.

Unequal appraisal protest (§41.41(a)(2)): Your property is appraised at a higher percentage of market value than comparable properties. Even if your absolute value is defensible, if similar properties nearby are appraised lower, you have an unequal appraisal argument under Tax Code §23.01.

Both grounds can be raised in the same protest. For many commercial properties, the unequal appraisal argument is actually stronger than the pure market value argument — especially when your evidence of market value is limited.

Step 1: Know Your Deadline — May 15 Is Not Flexible

The protest deadline in Texas is May 15, or 30 days after the date printed on your Notice of Appraised Value, whichever is later. This deadline is statutory. There are no extensions. Missing it means paying the full appraised value for the entire tax year with no recourse until the following year.

A few important nuances:

When does the clock start? The 30-day window runs from the date the notice was mailed, not the date you received it. If you were out of town and received a late notice, the 30 days may already be running. Check the mailing date on the notice, not the date you opened the envelope.

What if I didn’t receive a notice? Under Tax Code §41.44(c), you can still protest if you didn’t receive notice and didn’t learn of the value until after the deadline — but this requires prompt action and documentation that you had no actual knowledge of the value in time to protest.

Portfolio owners: If you own multiple commercial properties across different appraisal districts, each has its own deadline tied to its own notice. Don’t assume they’re all May 15.

Step 2: File Your Notice of Protest

File a Notice of Protest (Form 50-132) with the relevant County Appraisal District before the deadline. This is a simple one-page form stating that you’re protesting the value and identifying the grounds.

Filing options vary by appraisal district:

• In person at the appraisal district office (get a date-stamped copy)
• By mail (use certified mail with return receipt — never regular mail)
• Online through the appraisal district’s e-file system (most major districts now offer this)
• By fax (confirm the fax number on the district’s official website, not from memory)

The form only needs to identify your property, the appraised value you’re disputing, and your grounds (market value, unequal appraisal, or both). You don’t need your evidence yet — that comes later. A timely, minimally complete protest form preserves your rights; you build your case between filing and the hearing.

Step 3: Build Your Evidence Package

The window between your filing date and your hearing date is when you do the real work. A strong evidence package for a commercial property protest typically includes some combination of:

Income and Expense Documentation

If ACAD used the income approach to value your property, your actual income data is your most powerful evidence. Compile:

• Rent rolls (current tenant names, leased square footage, monthly rent, lease expiration)
• Signed lease agreements for all current tenants
• Prior 2 years of operating expense statements (actual costs, not budget)
• Documentation of current vacancies and how long they’ve been vacant
• Any below-market lease rates with documentation explaining why (long-term tenant relationships, renewal concessions, market conditions at lease inception)

The appraisal district’s income approach assumes market rents and stabilized occupancy. If your actual situation differs materially — and for many commercial properties it does — that difference is your case.

Comparable Sales Evidence

Recent sales of similar commercial properties establish market value independently of the income approach. Effective comparable sales evidence includes:

• Properties of similar type, size, age, and condition
• Sales that occurred within 12–24 months of January 1 of the tax year
• Adjustments for differences between the comparable and your property
• Source documentation (deed records, commercial MLS, appraisal databases)

In thinner markets with fewer sales, comparable sales from neighboring counties with similar market characteristics can supplement local data.

Independent Appraisal or Broker Opinion of Value

For larger commercial properties, a formal appraisal from a licensed MAI (Member, Appraisal Institute) appraiser carries significant weight at both informal and ARB hearings. The cost — typically $3,000–$8,000 for a straightforward commercial property — is frequently recovered many times over in first-year tax savings. For smaller properties, a Broker Opinion of Value from a commercial real estate professional familiar with the local market can be effective at a lower cost.

Condition Documentation

Photographs, maintenance records, and contractor estimates documenting deferred maintenance, physical deterioration, or functional obsolescence that the appraisal district didn’t account for. If your HVAC is 25 years old and nearing replacement, that affects market value. Document it.

Unequal Appraisal Evidence

Under Tax Code §41.43, you can request the appraisal district’s appraisal records for comparable properties. A table showing that your property is appraised at a significantly higher ratio of market value than similar nearby properties is often compelling at the ARB level, particularly when the market value argument alone is challenging.

Step 4: The Informal Hearing

Most protests begin with an informal hearing — a meeting with an appraisal district appraiser (not the ARB) to discuss your evidence and attempt to negotiate a reduction without a formal hearing. This step is not required, but it’s almost always worth taking.

What to expect: You’ll meet with a staff appraiser for 15–30 minutes. They’ll review your evidence, ask questions, and either offer a reduction or hold the value. The informal meeting is typically where 70–80% of commercial protests resolve.

How to approach it: Be direct and professional. Lead with your strongest evidence — if your income data is compelling, present that first. Have your evidence organized and easy to follow. The appraiser has limited time and is evaluating many protests simultaneously; clear, organized evidence gets taken seriously.

When to accept: If the informal offer gets you within 10–15% of your target value, it may be worth accepting to avoid the ARB process. If it falls well short, decline and proceed to the ARB.

Get it in writing: If you reach an agreement at the informal stage, make sure you receive written documentation of the agreed value before leaving.

Step 5: The ARB Hearing

If the informal hearing doesn’t produce a satisfactory resolution, your case goes to the Appraisal Review Board — a panel of local citizens empowered under Texas Tax Code to hear evidence and determine appraised values.

Scheduling: After you indicate you want an ARB hearing, the appraisal district will schedule one and notify you of the date, time, and location. You have the right to at least 15 days’ notice of your hearing date under Tax Code §41.66.

Evidence exchange: At least 14 days before the hearing, the appraisal district must deliver its evidence to you, and you must deliver your evidence to them. Use this exchange deadline strategically — review what the district is relying on and prepare to address weaknesses in their analysis.

At the hearing:

1. The ARB panel (typically 3 members) presides
2. The appraisal district presents its case and evidence first
3. You present your case and evidence
4. Both sides can question each other
5. The ARB deliberates and announces its determination

Burden of proof: Under Tax Code §41.43, if your property is valued at $1 million or more, the appraisal district bears the burden of establishing market value. Below $1 million, the burden falls on you as the protesting party.

Conduct: Be professional, organized, and concise. ARB members are volunteers. The ones who make decisions well respond to clear evidence presented efficiently — not to lengthy arguments about the unfairness of the system.

Step 6: After the ARB — Your Options

The ARB issues a written order within a few days of your hearing. If you’re satisfied with the result, do nothing — the new value becomes your appraised value for the tax year.

If you’re not satisfied, Texas law gives you several post-ARB options:

Appeal to district court (Tax Code §42.01): File a petition in the district court of the county where the property is located within 60 days of receiving the ARB order. District court appeals require legal counsel and a formal appraisal as evidence — they’re appropriate for larger properties where the stakes justify the cost.

Binding arbitration (Tax Code §41A): For properties valued at $5 million or less (or residential homesteads at any value), you can request binding arbitration instead of district court. Arbitration is faster and cheaper than litigation, though the decision is final with limited appeal rights.

SOAH appeal: State Office of Administrative Hearings appeals are available for industrial and utility properties under certain circumstances.

For most commercial properties, the practical decision point is whether the potential additional reduction from a district court appeal justifies the legal costs — typically $5,000–$20,000+ for a straightforward commercial case. At a 30% contingency model, the math favors appeal only when the remaining overassessment is significant.

The Contingency Model: How Professional Representation Works

Professional property tax protest firms — including LowerMyCommercialTax.com — typically work on contingency: you pay a percentage of first-year savings only, with no fee if there’s no reduction.

This model aligns incentives. Your representative has every reason to pursue the maximum reduction through every available stage. You bear no upfront cost and no risk of paying for an unsuccessful effort.

The standard contingency rate in Texas is 30% of first-year savings. On a $2 million commercial property with a $300,000 reduction and a combined tax rate of 2.4%, the first-year savings is $7,200 — a contingency fee of $2,160 against annual savings you keep every year the value stays reduced.

What Happens to Your Value Next Year

A successful protest reduces your value for the current tax year only. The appraisal district can re-appraise your property the following year — and often does. However, a well-documented protest creates a record of the evidence that supported your reduction, which makes it easier to protest in subsequent years if the district attempts to raise the value back up.

The most effective strategy is consistent annual protest, particularly for commercial properties where values can change significantly year to year based on income performance.
