The deadline to file a property tax protest with the Harris County Appraisal District (HCAD) in 2025 is May 15, 2025, or 30 days after you receive your appraisal notice, whichever is later. Missing this deadline means losing your right to protest your property valuation for the year. Here’s what Houston homeowners need to know:

Key Dates for 2025 HCAD Protests

  • Appraisal Notices Sent: Typically mailed in late March to early April 2025. Check your mailbox or HCAD’s online portal for your notice.
  • Protest Deadline: May 15, 2025, or 30 days after receiving your notice.
  • Informal Hearings: Scheduled between May and July 2025. These are your first opportunity to negotiate with HCAD.
  • Formal Appraisal Review Board (ARB) Hearings: Held between May and July 2025 if no agreement is reached during the informal hearing.

Eligibility to Protest

  • Homeowners: If you own property in Harris County, you are eligible to protest your property’s assessed value.
  • Rental or Investment Properties: Owners of non-homestead properties can also protest.
  • Late Filers: If you miss the deadline, you may still file a late protest under certain conditions, such as clerical errors or incorrect notices.

Why Protest?

Protesting your property tax appraisal can be beneficial for several reasons:

  • Overvaluation: HCAD may overestimate your property’s market value, leading to higher taxes.
  • Equity Issues: If similar properties in your area are valued lower, you can argue for a reduction.
  • Errors: Mistakes in property details (e.g., incorrect square footage) can be corrected.

Bring your completed protest form, evidence (e.g., recent property photos, comparable sales, or repair estimates), and a copy of your appraisal notice.

The deadline for filing a protest for the 2025 tax year is May 15, 2025, or 30 days after your appraisal notice is mailed, whichever is later.

Building Your Case: Required Evidence Checklist & Templates

Start gathering your evidence early to ensure you meet the deadline.

Key Evidence to Gather

  1. Comparable Sales (Comps):

    • Use HCAD’s online tools or platforms like TaxLasso to quickly find accurate comps.

  2. Photos of Property Issues:

    • Document any structural problems, needed repairs, or unique issues that lower your property’s value.

  3. Appraisal Reports:

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

The Hearing Process: What to Expect

If you’ve filed a protest with the Harris County Appraisal District (HCAD), understanding the hearing process is crucial to achieving a fair property valuation. Here’s what Houston homeowners need to know:

Key Steps in the Hearing Process

  1. Notification of Hearing Date: After filing your protest, HCAD will notify you of your hearing date, typically scheduled between May and July. Ensure your protest is filed by the April 30 deadline to secure your spot.
  2. Preparation: Gather evidence to support your case, such as recent comparable property sales, photos of property damage, or appraisal reports.
  3. Informal Hearing: Most protests start with an informal hearing with an HCAD appraiser. This is your chance to present evidence and negotiate a lower valuation.
  4. Formal Hearing (if needed): If no agreement is reached, you’ll proceed to a formal hearing with the Appraisal Review Board (ARB). This is a more structured process, similar to a mini-trial.

What to Expect During the Hearing

  • Time Commitment: Informal hearings typically last 15-30 minutes, while formal hearings can take 1-2 hours.
  • Evidence Presentation: Be concise and focus on data-driven arguments, such as recent sales of comparable properties or documented issues affecting your home’s value.
  • Outcome: You’ll receive a decision on the spot or within a few days. If unsatisfied, you can escalate to binding arbitration or district court.

When to Hire a Property Tax Consultant

Hiring a property tax consultant can save you time, money, and stress—but knowing when to hire one is key. Here’s when it makes sense to bring in a professional:

1. Your Property Valuation Feels Unfair

If your Harris County Appraisal District (HCAD) valuation seems too high compared to similar homes in your area, a consultant can help. For example, if your home is valued at $400,000 but comparable homes are valued at $350,000, a consultant can gather evidence and negotiate on your behalf.

2. You’re Short on Time or Expertise

The HCAD protest deadline for 2025 is May 15 (or 30 days after you receive your notice, whichever is later). If you’re too busy to gather evidence, file paperwork, or attend hearings, a consultant can handle it all for you.

3. You Want to Maximize Savings Without the Hassle

DIY protests can take hours of research and preparation, while hiring a legal firm can cost thousands. TaxLasso offers a smarter alternative: it takes just 5 minutes to submit your property details, and their team of experts handles the rest—saving you time and money while delivering professional-level results.

4. You’ve Tried Protesting Before and Failed

If your past protests were unsuccessful, a consultant can identify mistakes and strengthen your case. For example, they might uncover errors in HCAD’s data or provide more compelling comparable sales.

5. You’re Facing a Complex Situation

If your property has unique features (e.g., damage, zoning issues, or recent renovations), a consultant can ensure these factors are properly considered in your valuation.

For Houston homeowners, TaxLasso is the ideal middle ground: it’s faster and more affordable than DIY, and it’s thousands of dollars cheaper than hiring a legal firm. With just 5 minutes of your time, you can secure professional help to lower your property taxes.
