Key Property Tax Stats

Last updated: October 9, 2026

Districts typically value this property type with the income approach, which the Comptroller says uses income and expense data to estimate what an investor would pay for the income stream (Texas Comptroller). It is most suitable for properties such as apartments, retail and office buildings.
When the income method is used, the chief appraiser must analyze comparable rent, expense and capitalization-rate data (Tax Code §23.012).
You can ask the district for the data, schedules and formulas it will use at the hearing (Tax Code §41.461).
For 2026, the 20% circuit breaker applies only to non-homestead real property valued at $5,320,000 or less and expires December 31, 2026 (Texas Comptroller).

Biggest Pain Points

Remote Work Changed Office Demand

Vacancy, lease-up time and concessions in your submarket may have changed since the district last modeled your building. When the income method is used, the chief appraiser must base projections of future rent or income and expenses on reasonably clear and appropriate evidence and consider historical trends (Tax Code §23.012). Compare your rent roll and vacancy with those assumptions.

Your Building Is Competing with Available Space

Competing space, including sublease space, can limit the rents your building can achieve. The statute directs the chief appraiser to consider current supply and demand factors and competing properties under construction (Tax Code §23.012). Document available space in your submarket.

Building Class and Condition Matter

Use comparables of the same class, age and condition as your building. Older buildings may need costly upgrades to compete, which the cost method must reflect as physical, functional or economic obsolescence (Tax Code §23.011).

How it Works

1. Free Office Building Analysis

Provide property address and square footage. We review vacancy trends, available sublease space, and actual vs. market rents.

2. We Document Your Submarket

We gather market data on submarket vacancy, available space and rents, and test it against the district's assumptions.

3. We File Market-Based Protests

We use actual office market data (vacancy, availability, rent trends) and your leases to test the district's value.

4. Know What It Costs

Commercial protests are handled through TaxDrop Pro, our full-service option.
