With rising property values and tax rates in 2025, it’s crucial to take action to lower your tax bill. This guide will walk you through the process of contesting your property taxes in Harris County, from gathering evidence to filing your protest.

Let’s get started!

Key Terms & Concepts

Understanding the key terms and concepts is essential for Houston homeowners looking to contest their property taxes in Harris County. Here’s what you need to know:

Property Tax Valuation

  • Market Value: The estimated price your property would sell for in the current market, determined annually by the Harris County Appraisal District (HCAD).
  • Appraised Value: The value HCAD assigns to your property for tax purposes. This is the figure you can contest if it’s higher than your property’s true market value.
  • 2025 Valuations: HCAD will release 2025 property valuations in early 2025. Homeowners have until May 15, 2025 (or 30 days after receiving their notice, whichever is later) to file a protest.

Grounds for Protest

  • Overvaluation: If HCAD’s appraised value exceeds your property’s market value.
  • Unequal Appraisal: If your property is valued higher than similar properties in your area.
  • Exemptions: Ensure you’re receiving all eligible exemptions (e.g., homestead, over-65, or disability).

How to Contest Property Taxes

  1. Review your 2025 appraisal notice from HCAD.
  2. Gather evidence, such as recent sales of comparable properties or a professional appraisal.
  3. File a protest online, by mail, or in person before the deadline.

Eligibility

  • Who Can Protest? Any property owner in Harris County can protest their property tax valuation, including homeowners, businesses, and even renters (with the owner’s permission).
  • Reasons to Protest: Common grounds include incorrect property details (e.g., square footage, condition), unequal appraisal (your home is valued higher than comparable properties), or market value disputes.

Deadlines

  • Key Dates for 2025:
    • May 15, 2025: Deadline to file a protest with HCAD.
    • July 2025 (or 30 days after receiving your notice): Informal hearing deadline.
    • August 2025 (or 45 days after your informal hearing): Formal hearing deadline.

Requirements

  • Documents Needed: Gather your property tax notice, recent appraisals, photos of your property, and comparable sales data (comps) to support your case.
  • Filing Options: You can file online through HCAD’s portal, by mail, or in person.

Gathering Evidence & Documentation Checklist

To successfully contest your property taxes in Harris County, gathering strong evidence and documentation is critical. Start early, as the deadline to file a protest is typically May 15 (or 30 days after you receive your appraisal notice). Here’s a step-by-step checklist to ensure you’re prepared:

Key Documents to Gather

  1. Appraisal Notice: Review your 2025 HCAD notice for your property’s assessed value and any errors.
  2. Property Details: Collect your property’s square footage, age, condition, and any unique features (e.g., foundation issues, outdated systems).
  3. Comparable Sales (Comps): Find recent sales of similar properties in your neighborhood (within the last 6-12 months) to prove your home is overvalued. Use HCAD’s online tools or platforms like TaxLasso to streamline this process.

Evidence to Support Your Case

  • Photos: Document any damage, repairs needed, or factors that reduce your property’s value.
  • Repair Estimates: Include quotes for major repairs (e.g., roof, plumbing) to show your home’s condition.
  • Market Analysis: Use tools like TaxLasso to generate a professional-level market analysis in just 5 minutes, saving hours of DIY research.

Organize Your Case

  • Highlight Errors: If HCAD’s records are incorrect (e.g., wrong square footage), provide proof like a recent survey or floor plan.
  • Prepare a Summary: Create a clear, concise summary of your evidence to present during your protest.

By following this checklist and leveraging tools like TaxLasso, you can confidently contest your Harris County property taxes and potentially save hundreds or thousands of dollars in 2025.

The Hearing Process

If you’re contesting your property taxes in Harris County, understanding the hearing process is critical to achieving a fair valuation. Here’s how it works:

Informal Hearing

  • What It Is: The first step in the protest process, where you meet with a HCAD appraiser to present evidence supporting your case.
  • Key Details:
    • No formal rules of evidence apply, making it less intimidating.
    • Bring documentation like recent sales data, repair estimates, or photos of property issues.
    • Many homeowners achieve reductions at this stage, avoiding the need for a formal hearing.
  • Timeline: Informal hearings typically occur between May and July 2025.

Formal Hearing

  • What It Is: If you’re unsatisfied with the informal hearing outcome, you can escalate to a formal hearing before the Appraisal Review Board (ARB).
  • Key Details:
    • The ARB is a neutral panel that reviews evidence from both you and HCAD.
    • You must present a strong case with comparable sales, appraisal reports, or other supporting data.
    • Decisions are binding, so preparation is crucial.
  • Timeline: Formal hearings usually take place between June and August 2025.

After the Decision & Appeals

Once you’ve received a decision on your property tax protest in Harris County, it’s important to understand your options and next steps:

If Your Protest is Successful

  • Reduced Valuation: Your property’s assessed value will be adjusted, lowering your tax bill for the current year (e.g., 2025).
  • Refund or Adjustment: If you’ve already paid your taxes, you may receive a refund or credit for the overpayment.
  • Future Impact: A successful protest can influence your property’s valuation in subsequent years, potentially saving you more over time.

If Your Protest is Denied

  • File an Appeal: You have the right to appeal the decision to the Harris County Appraisal Review Board (ARB) or district court, typically within 30 days.
  • Gather Evidence: Strengthen your case with updated comparable sales data, appraisals, or photos of property issues.
