How to File a Property Tax Protest in Harris County (Step-by-Step)

The deadline to file a property tax protest in Harris County is May 15, 2025, or 30 days after you receive your appraisal notice, whichever is later. Missing this deadline means losing your chance to challenge your property valuation for the year.

Here’s how to file your protest step-by-step:

Step 1: Review Your Appraisal Notice

• Check your Harris County Appraisal District (HCAD) notice for your property’s assessed value.
• Look for errors in property details (e.g., incorrect square footage, bedroom count, or condition).

Step 2: Gather Evidence

• Collect comparable sales data (comps) for similar properties in your area.
• Document any issues that lower your property’s value (e.g., needed repairs, flooding risks).

Step 3: File Your Protest

• Online: Use the HCAD iFile system to submit your protest electronically.
• By Mail: Send a written protest to HCAD at 13013 Northwest Freeway, Houston, TX 77040.
• In Person: Visit the HCAD office to file your protest.

Step 4: Prepare for Your Hearing

• HCAD will schedule an informal hearing with an appraiser. Bring your evidence and be ready to negotiate.
• If unsatisfied, request a formal hearing with the Appraisal Review Board (ARB).

Step 5: Consider Professional Help

• DIY: Filing on your own can take hours of research and preparation.
• Legal Firms: Hiring a firm can cost thousands of dollars.
• TaxLasso: Save time and money with TaxLasso, which takes just 5 minutes to file your protest and provides professional-level insights without the high cost.

By acting before the deadline and using the right tools, you can potentially lower your property tax bill significantly.

Required Documentation & Evidence for a Successful Protest

To file a successful property tax protest in Harris County, you must provide required documentation and evidence to support your case. The Harris County Appraisal District (HCAD) will only consider your protest if you submit compelling proof that your property’s assessed value is inaccurate. Here’s what you need:

Key Evidence to Gather

1. Comparable Sales (Comps):

   • Provide recent sales data (within the last 6-12 months) of similar properties in your neighborhood.
   • Use HCAD’s online tools or platforms like TaxLasso to quickly access accurate comps.

2. Photos of Property Issues:

   • Document any structural problems, damage, or maintenance issues that reduce your property’s value.

3. Appraisal Reports:

   • If you’ve had a recent appraisal, include it as evidence.

4. Repair Estimates:

   • Submit estimates for repairs or renovations needed to address property issues.

5. Income and Expense Statements (for rental properties):

   • If your property generates income, provide financial statements to show lower-than-expected returns.

Why Evidence Matters

HCAD relies on data to assess property values. Without proper documentation, your protest may be dismissed. For example, if your home is valued at $400,000 but comparable homes sold for $350,000, you must provide sales data to prove your case.

Save Time with TaxLasso

Gathering evidence can take hours, but TaxLasso simplifies the process. In just 5 minutes, TaxLasso provides professional-level insights and comps, saving you time and effort compared to DIY research.

• If you’re satisfied with the ARB’s decision, your property tax bill for 2025 will reflect the adjusted value.
