Alternatives to Online Protests

Here’s what you need to know to take action before the last day to protest property taxes in Harris County (typically May 15 or 30 days after receiving your appraisal notice).

1. In-Person Protest

  • Visit the Harris County Appraisal District (HCAD) office to file your protest in person.

2. Mail or Fax Your Protest

  • Submit a written protest via mail or fax to HCAD. Include your property details, reasons for protest, and supporting documentation.
  • Ensure your protest is postmarked or faxed by the deadline to avoid missing the window.

3. Hire a Property Tax Consultant or Legal Firm

  • Professional firms can handle the entire protest process for you, but this often costs thousands of dollars.
  • While effective, this option may not be cost-effective for homeowners seeking affordable solutions.

DIY vs. Professional Help

Deciding between DIY and professional help for your Harris County property tax protest depends on your time, expertise, and goals. DIY can save money but requires hours of research, evidence gathering, and navigating the Harris County Appraisal District (HCAD) system. If you miss the last day to protest property taxes in Harris County (typically May 15 or 30 days after receiving your notice in 2025), you lose your chance to appeal. Professional help, like hiring a legal firm, can be costly, often taking a percentage of your savings.

What Happens If You Miss the Deadline?

If you miss the deadline to protest your property taxes in Harris County, you lose the opportunity to challenge your property valuation for the year. The last day to protest property taxes in Harris County for 2025 is May 15, 2025, or 30 days after your appraisal notice is mailed, whichever is later. Missing this deadline means:

  • No Appeal for 2025: You cannot dispute your property tax valuation for the current tax year, potentially leaving you with higher taxes.
  • Higher Tax Bills: Without a protest, you may pay more than necessary if your property is overvalued.
  • No Refunds: If your property is later found to be overvalued, you won’t receive a refund for overpaid taxes.

What Can You Do If You Miss the Deadline?

  1. Prepare for Next Year: Mark your calendar for the 2026 protest deadline (typically May 15) and gather evidence (e.g., comparable property values, photos of property issues) early.
  2. Check for Errors: Even if you miss the deadline, review your appraisal notice for errors. If you find a mistake, contact the Harris County Appraisal District (HCAD) to correct it.
  3. Explore Other Options: If your tax bill is unaffordable, look into payment plans or exemptions you may qualify for, such as homestead or senior exemptions.
