How it works

  1. Find your home in the public Harris County appraisal records.
  2. We pull comparable properties in your neighborhood, matched by size, age, and quality.
  3. If your appraised value per square foot is above the comparable median, you have grounds for an unequal-appraisal protest (Texas Property Tax Code §41.43(b)(3)).
  4. We generate your evidence packet and written argument, then you file it yourself through HCAD iFile. Free.
Not legal, tax, or appraisal advice. HelpMeProtest provides public-record data and automated analysis to help you file your own property-tax protest. We are not your agent or representative, we are not a registered property tax consultant, and we do not file on your behalf. HelpMeProtest is an independent service and is not affiliated with, endorsed by, or acting on behalf of any appraisal district or government agency. No outcome is guaranteed. The Harris County protest deadline is generally May 15 (or the next business day), and you are responsible for filing on time.
