Everything you need to protest your HCAD assessment and reduce your property taxes in Houston and Harris County
Harris County is the largest county in Texas and the third-largest in the United States, encompassing Houston and dozens of surrounding communities. The Harris County Appraisal District (HCAD) appraises over 1.8 million properties each year, and property owners have the right to protest their appraised value if they believe it is inaccurate.
With rapidly changing property values in the Houston metro area, many homeowners find that their assessments don't reflect actual market conditions. Filing a protest is free and can result in significant tax savings.
Follow these steps to file a successful property tax protest with the Harris County Appraisal District:
The strength of your evidence determines the outcome of your protest. Here's what HCAD appraisers and the ARB consider most persuasive:
Find 3-5 recent sales of similar properties in your area that sold for less than your appraised value. Focus on homes with similar square footage, age, lot size, and condition within 1 mile of your property. Sales within the last 6-12 months carry the most weight.
Document any deferred maintenance, foundation problems, roof damage, outdated systems, flood damage history, or other conditions that reduce your property's value. Photos and repair estimates from licensed contractors are particularly effective.
Texas law requires that properties be appraised uniformly. If similar homes in your neighborhood are appraised for less per square foot than yours, you can argue unequal appraisal. HCAD's property search tool lets you check neighboring values.
Proximity to commercial development, highways, power lines, flood zones, or other negative influences can reduce property value. Document any external factors that affect your property's desirability or marketability.

If you miss this deadline, you lose your right to protest for that tax year. We strongly recommend filing as early as possible.
You can file a protest with HCAD online through iFile at hcad.org, by mail using Form 41.44 (Notice of Protest), or in person at the HCAD office at 13013 Northwest Freeway, Houston, TX 77040. The online method is fastest and provides instant confirmation of your filing.
Strong evidence includes comparable sales of similar homes that sold for less than your assessed value, photos of property damage or needed repairs, independent appraisals, and documentation of any factors that reduce your property's value such as neighborhood issues, flooding risk, or structural problems. The more specific and documented your evidence, the stronger your case.
Approximately 70-80% of Harris County property tax protests result in some reduction. Property owners who present strong comparable sales evidence and attend their hearing typically achieve the best results, with average reductions of 10-15% of assessed value. Even if you're unsure, it's worth filing — there is no cost and no risk of your value being increased as a result of protesting.
