Houston Property Tax Evidence Package

Why Evidence Decides Your Property Tax Protest

When you protest your property taxes in Houston, you are making a case to the Harris County Appraisal District that your home's assessed value is too high. The appraisal district will not lower your value because you feel the number is wrong — they need data. Property owners who walk into hearings with organized, relevant evidence consistently get better results than those who show up unprepared.

A property tax evidence package gives you the data you need in a format the appraisal district takes seriously. Instead of trying to pull together your own spreadsheets from public records, you get a report that is structured the way appraisers are trained to evaluate property values.

What Is Included in Your Evidence Package

Our Houston property tax evidence package is built from real appraisal district data, using the same types of analysis that HCAD evaluates during a protest:

Equity Analysis

Texas law requires that properties be assessed uniformly. The report compares how similar nearby properties are appraised, adjusted for differences in square footage, age, lot size, and features. If your home is assessed higher than comparable properties, that is strong evidence for a reduction. This equity analysis is the foundation of every report we generate.

Comparable Sales

When recent nearby home sales support a lower value, the report includes them. Sales comps reflect what buyers are actually paying in the current market and are highly persuasive at hearings. Sales data is included if helpful to your case.

Property-Specific Adjustments

Every comparable property in the report is adjusted to account for differences versus your home — square footage, year built, lot size, and features. This ensures the comparison is apples-to-apples, which is exactly what the appraisal review board expects to see.

How Your Evidence Package Is Built

When you enter your property address, our system analyzes data from the appraisal district and recent real estate transactions to build your report. It identifies the most relevant comparable properties based on proximity, property characteristics, and sale dates. The analysis is then formatted into a professional report that you can upload through HCAD's iSettle portal or print for your hearing.

The entire process takes just a few minutes. You do not need experience with property tax data or appraisal methods — the report is designed so any homeowner can present it effectively at their hearing.

Get Your Evidence in 4 Steps

Beyond Harris County

The evidence methodology behind this package is not limited to HCAD. The same approach — equity analysis, comparable sales, and property-specific adjustments — is used to build protest evidence for all five Houston-area counties we cover. Whether your property is in Harris County, Fort Bend, Montgomery, Galveston, or Brazoria, your report uses the same proven framework adapted to each county's appraisal district data.

Each county-specific report is formatted for that district's submission process. Explore your county's report: Harris County (HCAD), Fort Bend, Montgomery County, Galveston County, and Brazoria County.
