Whether you’re new to the process or looking to refine your approach, this guide will help you confidently navigate the system and keep more money in your pocket.

Are You Eligible to Appeal?

Yes, you are eligible to appeal your property tax assessment in Houston if you believe your property has been overvalued by the Harris County Appraisal District (HCAD). Most homeowners can appeal, but understanding the specifics can help you take action confidently.

Key Eligibility Criteria

• Timing Matters: Appeals must be filed by the deadline, typically May 15 or 30 days after you receive your appraisal notice. For 2025, mark these dates early to avoid missing your window.
• Overvaluation Concerns: If your property’s assessed value is higher than its market value or comparable homes in your area, you likely have grounds for an appeal.
• Errors in Property Details: Incorrect square footage, bedroom count, or other property details can justify an appeal.

Why Appeal?

• Save Money: A successful appeal can lower your property tax bill by thousands of dollars. For example, reducing a $400,000 valuation by 10% could save you over $1,000 annually.
• Level the Playing Field: HCAD’s mass appraisal system often leads to inaccuracies. Appealing ensures your property is assessed fairly.

How to Appeal

1. DIY Approach: Research comparable properties and file your appeal. However, this can take hours and requires navigating complex processes.
2. Hire a Legal Firm: Professionals can handle everything, but fees can eat into your savings.
3. Use TaxLasso: The ideal middle ground. TaxLasso takes just 5 minutes to submit your appeal, offering professional-level insights without the high cost of legal firms. It’s thousands of dollars cheaper and gives you full control over the process.

If you’re unsure about your eligibility or need help, TaxLasso simplifies the process, ensuring you maximize your savings with minimal effort.

Deadlines & Local Requirements

Deadlines for Houston Property Tax Appeals

Key Deadline for 2025 Appeals:
The deadline to file a property tax protest in Houston for the 2025 tax year is May 15, 2025, or 30 days after you receive your appraisal notice, whichever is later. Missing this deadline means you lose your right to appeal for the year.

Local Requirements to File a Protest

• Appraisal Notice: You must have your official appraisal notice from the Harris County Appraisal District (HCAD). This document includes your property’s assessed value and instructions for filing a protest.
• Filing Methods: You can file online through the HCAD website, by mail, or in person. Online filing is the fastest and most convenient option.
• Evidence Submission: To strengthen your case, gather evidence such as recent sales of comparable properties, photos of property damage, or repair estimates. These must be submitted before your hearing date.

Why Deadlines Matter

• Late Filings Are Not Accepted: HCAD strictly enforces the May 15 deadline. If you miss it, you’ll have to wait until the next tax year to appeal.
• Early Action Saves Money: Filing early gives you more time to prepare evidence and increases your chances of reducing your tax burden.

Evidence You Need to Win

To win your property tax appeal in Houston, you need strong, specific evidence that proves your home’s assessed value is inaccurate. Without compelling proof, your protest is unlikely to succeed. Here’s what you need to gather:

1. Comparable Sales (Comps)

• Collect data on recent sales of similar homes in your neighborhood (within the last 6-12 months).
• Focus on homes with similar square footage, age, and features.
• Example: If your home is valued at $400,000 but nearby comps sold for $350,000, this is strong evidence your assessment is too high.

2. Photos of Property Issues

• Document any defects or conditions that lower your home’s value, such as foundation cracks, roof damage, or outdated systems.
• Example: A cracked foundation could reduce your home’s value by 10-15%, which directly impacts your tax assessment.

3. Appraisal Reports

• If you’ve had a professional appraisal done recently, include it as evidence.
• Example: A 2025 appraisal showing your home is worth $375,000 versus the county’s $400,000 valuation is a powerful argument.

4. Market Trends

• Use data showing declining property values in your area, especially if the market has softened since your last assessment.
• Example: If Houston’s median home price dropped 5% in 2025, this trend can support your case.

If you believe your property tax valuation is too high, you have the right to appeal. Here’s a clear, step-by-step process to help Houston homeowners navigate the appeal process effectively:

1. Review Your Notice of Appraised Value

• In early 2025, you’ll receive a Notice of Appraised Value from the Harris County Appraisal District (HCAD).
• Check the assessed value and compare it to recent sales of similar homes in your area. If it’s higher, you may have grounds for an appeal.

  • Photos of property damage or issues that lower your home’s value.
  • Appraisal reports or repair estimates.

3. File Your Protest

• Submit your protest online through HCAD’s iFile system by the May 15, 2025, deadline (or 30 days after receiving your notice, whichever is later).
• Clearly state your reasons for protesting, such as unequal appraisal or incorrect property details.

4. Prepare for the Hearing

• Choose between an informal hearing (with an appraiser) or a formal hearing (with the Appraisal Review Board).
• Organize your evidence and practice presenting your case concisely.

5. Attend the Hearing

• Present your evidence professionally and calmly. Focus on facts, not emotions.
• If successful, your property value will be adjusted, lowering your tax bill.

5 Common Mistakes to Avoid

5 Common Mistakes to Avoid When Appealing Your Property Taxes in Houston

Appealing your property taxes can save you thousands of dollars, but many Houston homeowners make avoidable errors that hurt their chances of success. Here are the most common mistakes to avoid and how to address them effectively:

1. Missing the Deadline

The deadline to file a property tax protest in Houston is typically May 15 or 30 days after you receive your appraisal notice, whichever is later. Missing this deadline means losing your chance to appeal for the year. Set reminders and act early to avoid this costly oversight.

2. Not Reviewing Your Appraisal Details

Many homeowners skip reviewing their property’s appraisal details, such as square footage, room count, or condition. Errors in these details can inflate your valuation. For example, if your home is listed as 2,500 sq. ft. but is actually 2,200 sq. ft., correcting this could lower your taxable value significantly.

3. Failing to Gather Comparable Sales Data

Comparable sales (comps) are critical to proving your home is overvalued. Avoid relying on generic online estimates like Zillow. Instead, use recent sales of similar homes in your neighborhood. Tools like TaxLasso streamline this process by providing professional-level comps in just 5 minutes, saving you hours of research.

4. Overlooking Exemptions or Special Valuations

Many homeowners miss out on exemptions like homestead, over-65, or disability exemptions, which can reduce your taxable value. For 2025, ensure you’ve applied for all eligible exemptions before appealing.

5. Going It Alone Without Professional Support

While DIY appeals are possible, they often lack the expertise needed to succeed. Hiring a legal firm can cost thousands, but TaxLasso offers a middle ground: professional-level insights and results at a fraction of the cost, with full control over your appeal.

By avoiding these mistakes and leveraging tools like TaxLasso, Houston homeowners can maximize their chances of a successful property tax appeal without unnecessary stress or expense.
