Complete guide to protesting your Harris County property taxes in 2026. Learn HCAD deadlines, how to build a comparable sales case, and what the county records actually show about outcomes.
The Harris County Appraisal District is one of the largest appraisal districts in the country, responsible for valuing over 1.8 million parcels. HCAD uses a computer-assisted mass appraisal (CAMA) system that estimates value using statistical models — applying broad market trends to entire neighborhoods rather than assessing each home individually. This approach is fast and scalable, but inherently imprecise. Your home gets grouped with comparable properties in your area and a value is assigned based on average market trends. If your home has issues the model can't see — foundation problems, outdated systems, an unusual floor plan, backing to a commercial property or busy road — your assessment will be inflated.
Missing the protest deadline means waiting a full year to challenge your assessment. Texas Tax Code § 41.44 sets the protest deadline as the later of May 15, 2026 OR 30 days after HCAD mailed your Notice of Appraised Value. HCAD typically mails notices in April. Check the date on your notice — your personal deadline may be later than May 15.
Texas Tax Code gives you two distinct arguments to make in your protest, and the strongest cases use both.
The informal hearing is your first opportunity to present evidence directly to an HCAD appraiser. This is where the majority of protests are resolved. The most effective evidence is comparable sales data — recent sales of homes similar to yours that sold for less than your assessed value.
Most Harris County property tax protest companies charge 25–50% of your first-year savings as a contingency fee. On a $2,000 reduction, that's $500–$1,000 in fees — every single year. TaxAppeal charges a flat $89. We pull your property data, analyze comparable sales, draft a formal protest letter citing Texas Tax Code § 41.41 and § 41.43, and file via USPS certified mail with return receipt. You keep 100% of your savings.

TaxAppeal USA is a self-service document-preparation and mail filing service. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not represent customers before any appraisal district, board of equalization, value adjustment board, or review board. Every protest and petition is prepared for the property owner, signed by the owner, and filed in the owner’s name. In Florida we also pay your county’s Value Adjustment Board filing fee on your behalf and mail your petition to the Clerk of the Value Adjustment Board. Your petition is signed by you as the property owner under section 194.011(3), Florida Statutes. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
