Texas Commercial Property Tax Protest Guide (Dallas, Collin, Tarrant Counties)

To protest a commercial property tax value in Texas you file a notice of protest with your county appraisal district by May 15th or 30 days after your value notice was mailed (whichever is later). You bring in evidence such as rent rolls, operating statements, repair bids and comparable values. The majority of cases are settled at an informal meeting or at the Appraisal Review Board (ARB). If you lose at the ARB you can go to district court, binding arbitration (for properties valued at $5 million or less) or SOAH (for values over $1 million).

Every spring a letter turns up from the appraisal district saying your strip center is worth 18% more than it was last year.

Your rents didn't go up 18% and your vacancy didn't drop, but your tax bill is going to behave exactly as it did.

That's why the owners are protesting. In Texas property taxes are often the single biggest item in a commercial building's budget. We manage commercial property throughout Dallas, Collin and Tarrant counties and spring is the time of year when the owners are calling us about this letter. Here's how the protest process actually works.

Why Commercial Property Tax Protests Matter in Texas

Texas has no state income tax so the local governments are absolutely reliant on property tax. A small change in value can equate to thousands of dollars a year.

Here's a simple example. Suppose the value of your office building goes from $3.0 million to $3.5 million. At a 2% combined tax rate that would see your bill go from $60,000 to $70,000.

Real rates will vary by city, by school district and by special district. The math is the same though. For every $100,000 of value you remove you save approximately $2,000 a year at that rate.

And it compounds. Next year's figure is often built on this year's figure. Skip a protest and you may end up paying for it twice.

Texas Commercial Property Tax Protest Deadlines and Timeline

The key deadline is May 15th (or 30 days after the appraisal district mails you their notice, whichever comes later). If you miss that deadline your options are going to get very limited very quickly.

The Texas Comptroller points out one trap: the 30 days starts to run from the date the district mails the notice, not from the date you receive it.

One more date to watch: an appeal following on from the ARB has its own short deadlines. We'll cover those below.

Dallas, Collin and Tarrant Appraisal Districts Compared

Each county has its own appraisal district. The protest rules are the same throughout the state, but each district has its own website, its own portal and its own hearing schedule.

If you own property in more than one county then you have to file separately in each one. A Plano building and a Fort Worth building means two protests, two portals and two hearing dates.

Some buildings cross a county line. Check which district your parcel is in prior to filing.

How to File a Commercial Property Tax Protest Step by Step

You can file via Form 50-132 or via your district's online portal. The Comptroller says any written notice will do as long as it names the property, the owner and what you're objecting to.

1. Read your notice of appraised value. Note the market value, last year's value, and the mailing date.
2. File your protest prior to the deadline. Check "value is over market value" and "value is unequal in comparison with other properties".
3. Request the evidence the appraisal district plans to use. You have a right to see it before the hearing.
4. Build your evidence package. Focus on income, condition, and comparable values.
5. Attend the informal meeting with an appraiser. Many commercial cases settle here.
6. If you don't settle, present your case at the formal ARB hearing.
7. Review the ARB's written order. Decide within the deadlines whether to appeal.

Want someone else to do it? File Form 50-162 to appoint an agent. In Texas property tax consultants are required to register with the Texas Department of Licensing and Regulation. Always ask for their registration number prior to signing anything.

What Evidence Wins a Commercial Property Tax Protest?

Evidence wins. Opinions don't. The Comptroller says it quite bluntly: "You can't just go to the hearing and say the appraisal district is wrong."

For commercial property the strongest arguments are generally going to be on the income side. You'll often see office and retail properties appraised on the basis of their net operating income. If your real income is lower than their model then that's the argument you'll want to make.

That unequal appraisal issue is a sleeper. You could well be at market value and still come out on top if the appraisals on similar buildings are lower. The Comptroller cites the median appraisal as proof of that point.

A quick tip from managing these buildings: get your January 1 rent roll in January. Reconstructing it in May with three suites having been turned over is not at all fun.

Can NNN Tenants Protest Commercial Property Taxes?

Yes, in some cases. If the lease requires the tenant to pay the owner's property taxes then the tenant can object, but only if the owner doesn't.

The Comptroller confirms that this right extends to leased land, buildings and personal property. A tenant can also request the chief appraiser to send them the value notice.

For those of you with NNN leases this is important. Your tenants pay the tax bill via their expense charges. Many of the leases will specify who files the protest. If yours doesn't then you need to make a decision before May, not during May.

What If You Lose at the ARB? Appeal Options Compared

You have three main routes after the ARB: district court, regular binding arbitration or SOAH. It's your property value that determines which of those you can go down.

Arbitration and SOAH are generally quicker and cheaper than going to court. Court is obviously the right route in the case of a large dispute where the tax savings are going to more than offset the cost of the legal fees.

Very large properties get their own lane as well. For 2026, commercial properties appraised at $62.883 million and over can request a special ARB panel.

The 20% Circuit Breaker Cap: What Changes in 2027

Since 2024 Texas has put a cap on annual appraisal increases at 20% for a large number of non-homestead properties. That's the circuit breaker limit.

The cap applies to real property valued at approximately $5 million or less (adjusted for inflation each year). For 2026 the Bexar Appraisal District has the cap at $5,320,000. You have to own the property for a full year first and the district will apply the cap automatically.

Here's the catch. The circuit breaker under Texas Tax Code section 23.231 expires December 31, 2026 unless the Legislature extends it.

If it does end, a smaller commercial building could see its full market value come on the tax roll in 2027. That could be a lot bigger jump than 20%. Check with your appraisal district as to the status of the cap prior to your 2027 notice coming in.

Common Commercial Property Tax Protest Mistakes

The vast majority of lost protests are due to missed dates or poor evidence. A number of errors will crop up again and again.

• Waiting for the notice before gathering records
• Arguing that taxes are "too high" instead of arguing value
• Bringing pro forma rents instead of actual January 1 rents
• Forgetting to check the unequal appraisal box
• Skipping the informal meeting, where many cases settle
• Missing the 30- or 60-day appeal deadlines after the ARB
• Filing a late business personal property rendition, which can trigger a penalty

Don't argue about emotion. The ARB doesn't set tax rates, it sets value. Bring the numbers, not the frustration.
