Who is Eligible to Appeal?

All Harris County homeowners are eligible to appeal their property tax assessments if they believe their property has been overvalued. This includes residential, commercial, and rental properties.

Key Deadlines for 2025

  • May 15, 2025: Deadline to file a property tax protest with the Harris County Appraisal District (HCAD).
  • July 1, 2025: Informal review meetings with HCAD typically conclude.
  • August 1, 2025: Final deadline for formal hearings with the Appraisal Review Board (ARB).

Missing these deadlines means waiting another year to appeal, so act early.

Understanding Your Assessment

Your property tax bill is based on HCAD’s assessed value of your home. Common reasons to appeal include:

  • Incorrect property details: Square footage, number of bedrooms, or lot size errors.
  • Market value discrepancies: Your home’s assessed value is higher than comparable properties in your area.
  • Unequal appraisal: Your property is taxed at a higher rate than similar homes.

Step-by-Step Appeal Process

If you believe your Harris County property tax valuation is too high, you can appeal it. Here’s a clear, step-by-step process to help Houston homeowners take action:

1. Review Your Notice of Appraised Value (NOAV)

In early 2025, Harris County will mail NOAVs to homeowners. Check your property’s appraised value, market value, and exemptions. If the value seems inflated, gather evidence like recent sales of comparable homes or repair estimates to support your case.

2. File a Protest with the Harris County Appraisal District (HCAD)

  • Deadline: May 15, 2025, or 30 days after receiving your NOAV, whichever is later.
  • File online at HCAD’s website or use tools like TaxLasso to streamline the process in just 5 minutes.

3. Prepare Your Case

Collect evidence: Comparable sales (comps), photos of property damage, or contractor estimates for repairs. Use TaxLasso to access professional-level insights and comps without spending hours researching.

4. Attend Your Informal Hearing

HCAD will schedule a meeting with an appraiser. Present your evidence clearly and professionally. If you’re uncomfortable negotiating, TaxLasso can provide expert guidance at a fraction of the cost of hiring a legal firm.

5. Request a Formal Hearing (if needed)

If unsatisfied with the informal hearing outcome, request a formal hearing with the Appraisal Review Board (ARB). Present your case again, or let TaxLasso handle the heavy lifting, saving you thousands compared to legal firms.

6. Receive Your Decision

The ARB will issue a final decision. If you still disagree, you can pursue further legal action, though this is rare.

By following this step-by-step appeal process, Houston homeowners can potentially lower their property tax bills. For a faster, more affordable alternative to DIY or legal firms, TaxLasso offers professional-level expertise in just 5 minutes, saving you time and money.

Winning Strategies, Evidence & Documentation Requirements

To successfully appeal your Harris County property tax assessment, you need a clear strategy, strong evidence, and proper documentation. Here’s how to maximize your chances of winning:

Key Strategies for Success

  1. Focus on Market Value: The most common and effective appeal strategy is proving your home’s market value is lower than the Harris County Appraisal District (HCAD) assessment. Use recent sales of comparable properties (comps) in your neighborhood to support your case.
  2. Highlight Errors: Review your property record for inaccuracies in square footage, room count, or condition. Even small errors can lead to overvaluation.
  3. Leverage Equity: If your home’s value is significantly lower than similar properties, emphasize this disparity to argue for a reduction.

Essential Evidence & Documentation

  • Comparable Sales: Provide 3-5 recent sales of similar homes in your area (within the last 6-12 months).
  • Photos & Repair Estimates: If your property has issues (e.g., foundation problems, outdated systems), include photos and repair estimates to justify a lower valuation.
  • Appraisal Reports: A professional appraisal can strengthen your case, though it’s not required.
  • HCAD Property Details: Double-check your property’s details on the HCAD website for errors.

Documentation Requirements for 2025 Appeals

For 2025 appeals, ensure all evidence is dated and relevant. HCAD typically requires:

  • Proof of comparable sales (MLS listings or Realtor reports).
  • Documentation of property condition (photos, repair invoices).
  • Any additional evidence supporting your claim (e.g., flood zone maps, neighborhood decline data).

Why TaxLasso is the Best Option

Appealing your property taxes can be time-consuming and complex. TaxLasso simplifies the process:

  • 5-Minute Setup: Save hours of research with professional-level insights.

ARB Hearing Survival Guide & Appeal Outcomes

Facing an ARB (Appraisal Review Board) hearing in Harris County? The key to success is preparation. Here’s what you need to know to survive your hearing and maximize your chances of a favorable outcome.

Key Steps to Prepare for Your ARB Hearing

  1. Gather Evidence: Collect recent comparable property sales (comps), photos of property damage, or repair estimates. Focus on data from 2024 or 2025 to ensure relevance.
  2. Understand the Process: ARB hearings are formal but homeowner-friendly. You’ll present evidence, and the board will decide if your property’s valuation is fair.
  3. Practice Your Pitch: Be concise and stick to facts. Highlight discrepancies in your property’s valuation compared to similar homes.

Common Appeal Outcomes

  • Reduction in Valuation: Many homeowners achieve a 10-20% reduction in their property’s assessed value, leading to significant tax savings.
  • No Change: If evidence is weak, the ARB may uphold the current valuation.
  • Increase in Valuation: Rare but possible if the ARB finds your property undervalued.

Common Mistakes to Avoid & Recent Policy Changes

When appealing your Harris County property taxes, avoiding common mistakes and staying updated on recent policy changes can save you time, money, and frustration. Here’s what you need to know:

Common Mistakes to Avoid

  • Missing Deadlines: The deadline to file a property tax protest in Harris County 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.
  • Not Gathering Evidence: Failing to provide comparable property data, photos of property damage, or other evidence weakens your case. Always document your property’s condition and research similar homes in your area.
  • Overlooking Exemptions: Ensure you’re taking advantage of all applicable exemptions, such as homestead, over-65, or disability exemptions. These can significantly reduce your taxable value.
  • DIY Pitfalls: While DIY appeals are an option, they often lack the professional insights needed to negotiate effectively. Many homeowners undervalue their evidence or miss key arguments.

Recent Policy Changes (2025)

  • Increased Homestead Exemption: Starting in 2025, the homestead exemption in Texas has increased from $40,000 to $100,000, potentially lowering your taxable value. Ensure your exemption is applied correctly.
  • New Online Protest Tools: Harris County has streamlined its appeal process with enhanced online tools, making it easier to file protests and submit evidence digitally.
  • Valuation Caps: Recent legislation has tightened caps on annual valuation increases for homestead properties, limiting how much your taxable value can rise each year.
