Your Assessment Looks Reasonable

Why Texas Commercial Property Owners Overpay on Taxes
County appraisal districts in Texas are required to assess every property at market value each year. But with hundreds of thousands of commercial properties to value, the mass appraisal process relies on broad assumptions that don't account for property-specific conditions.
Common Reasons for Commercial Over-Assessment
Commercial properties in Houston, Dallas, San Antonio, Austin, and Fort Worth are frequently over-assessed for several reasons. Appraisal districts may not account for deferred maintenance, high vacancy rates, below-market lease terms, or functional obsolescence. A warehouse built in the 1980s gets lumped in with newer Class A industrial space. A retail strip center with 30% vacancy gets valued the same as a fully-leased center across the street.
The income approach to value — the standard for commercial property valuation — requires accurate capitalization rates, operating expenses, and market rent data. County appraisers often use outdated or overly aggressive assumptions that inflate your assessed value.
The Cost of Not Protesting
If your commercial property is over-assessed by $200,000 at an effective tax rate of 1.8%, you're overpaying roughly $3,600 every single year. Over 5 years, that's $18,000 that could go back into your business. For larger properties, the numbers get into six figures fast.
How the Texas Commercial Property Tax Appeal Process Works
Filing a property tax protest in Texas is your legal right under the Texas Property Tax Code. The process is straightforward, but commercial appeals require more sophisticated evidence than residential protests.
Step 1: File Your Notice of Protest
You must file a Notice of Protest (Form 50-132) with your county appraisal district by May 15th or 30 days after your Notice of Appraised Value is mailed, whichever is later.
Step 2: Gather Your Evidence
The most effective evidence includes comparable sales data, an income and expense analysis using actual lease terms and operating costs, and documentation of any property condition issues that reduce value.
Step 3: Informal Hearing
Most county appraisal districts offer an informal hearing where you meet with a staff appraiser. Many commercial protests are resolved at this stage with a negotiated reduction.
Step 4: Appraisal Review Board (ARB)
If unresolved, your case goes to the ARB — a formal hearing where you present evidence and the appraisal district presents theirs. The panel makes a binding decision.
Step 5: Further Appeals
For commercial properties over $1 million, you can pursue binding arbitration or district court. These options are commonly used for high-value properties where the savings justify the effort.
