Texas provides property owners with several pathways to challenge inaccurate appraised values, even after the normal protest deadline has passed. One of the most powerful tools is Texas Property Tax Code 25.25(d), which allows owners to correct a value that exceeds market value by a significant margin. For commercial owners across San Antonio and Bexar County, this provision can oƯer real tax relief when the district’s valuation is simply not supported by the evidence.
In this guide, we cover how the 25.25(d) correction works, the thresholds required, how the rule diƯers for commercial and residential homestead properties, and when it makes sense to file. We also explain how Alamo Ad Valorem assists property owners in presenting strong supporting evidence for these late appeals.
What is a 25.25(d) Late Appeal in Texas?
Section 25.25(d) of the Texas Property Tax Code allows a property owner to request a correction to the appraised value after the May 15 deadline if the value is: • more than one third over market value for commercial and non-homestead property • more than one fourth over market value for residential homestead property.
This late correction motion can be filed until January 31 of the following tax year, which gives owners additional time to challenge a value when the district’s appraisal is clearly excessive.
A successful 25.25(d) correction often results in meaningful tax savings for commercial property owners across Bexar County.
Why 25.25(d) Matters for Commercial Property Owners in San Antonio
Commercial properties in San Antonio have experienced rapidly shifting values. When the appraisal district applies models or mass appraisal assumptions that do not reflect the actual market, it can lead to valuations that are not supportable.
The 25.25(d) process gives owners a second chance by correcting values where the district exceeded the statutory threshold. For example, if market evidence supports a value of 10 million, but the district appraised the property at 14 million, the property may qualify because the district exceeded the 1/3 threshold.
Common reasons commercial values qualify
- Incorrect income approach assumptions
- High vacancy not accounted for
- Capitalization rate applied too low
- Expense ratios not reflective of market
- Comparable sales misaligned with market conditions
- Construction type or use incorrectly coded
- Environmental or easement restrictions overlooked
When these issues push the value beyond the allowed margin, a 25.25(d) correction becomes a viable strategy.
Understanding the 1/3 Over Market Value Rule
For commercial and non-residential property, the threshold is clear. The value must be more than one third higher than the market value supported by evidence. This is not a discretionary standard. It is a numeric calculation that must be proven using credible data and analysis.
Example Calculation
If market value is 9 million, then:
9,000,000 x 1.33 = 11,970,000
If the appraisal district’s value is higher than 11,970,000, the property may qualify for correction.
This calculation is key to determining eligibility.
The 1/4 Rule for Residential Homestead Properties
Residential homesteads are treated diƯerently under Texas law. For these properties, the correction threshold is lower. A homestead qualifies if the appraised value is more than one fourth, or 25 percent, above market value.
Example
Market value: 300,000
300,000 x 1.25 = 375,000
If the district appraised the home above 375,000, it may qualify for a correction under 25.25(d).
This is a helpful relief option for homeowners who miss the standard protest deadline.
What Evidence Is Needed for a Strong 25.25(d) Case
Because the standard is numeric, evidence must be well-supported. Alamo Ad Valorem typically presents:
• Certified comparable sales
• Income approach valuations for commercial assets
• Expense ratios and rent rolls
• Capitalization rate studies
• Cost approach data when applicable
• Market condition adjustments
• External obsolescence or physical condition analysis
Appraisal districts often scrutinize late appeals closely, so the quality of the evidence is critical.
How the 25.25(d) Timeline Works in Bexar County
Owners may file a motion until January 31 of the year following the appraisal. For example, the 2024 value can be corrected until January 31, 2025.
Hearings are typically scheduled through the Bexar Appraisal Review Board, and supporting evidence must be filed before the hearing. Because the process moves quickly, preparation is essential.
When It Makes Sense to File a 25.25(d) Motion
A correction motion is often beneficial when:
• A standard protest was not filed
• New information was discovered after the deadline
• Market conditions shifted
• The district relied on incorrect data
• The valuation error is significant enough to cross the threshold
Commercial owners in San Antonio often pursue this option for multifamily, industrial, oƯice, retail, land, and hospitality assets where market data supports a lower value.
