10 Valid Reasons to Appeal Property Taxes (And How to Prove Your Case)

In 2025, Houston homeowners are facing rising property values and tax assessments. Ensuring fair and accurate taxes is more critical than ever. But how do you determine if you have a valid reason to appeal your property taxes, and how do you prove it? This guide explores 10 legitimate reasons to consider an appeal, from incorrect assessments to overlooked exemptions, and provides actionable steps to build a strong case. Whether you prefer a DIY approach or professional assistance, TaxLasso offers a streamlined process that saves time and money.

Top 10 Valid Reasons to Appeal

If you’re a homeowner in Houston, appealing your property tax assessment could save you thousands of dollars. Here are the top valid reasons to appeal in 2025:

  1. Incorrect Property Details
    Mistakes in your home's square footage, number of bedrooms, or other features can lead to a higher assessment. For instance, if your home is listed as 3,000 sq. ft. instead of its actual 2,500 sq. ft., your valuation may be unfairly high.

  2. Market Value Discrepancies
    If your assessed value exceeds recent sales of comparable homes in your neighborhood, you have grounds for an appeal. For example, similar homes selling for $350,000 while yours is assessed at $400,000 indicates a disparity.

  3. Overvalued Land
    Rapid area development can inflate land values. If your land is assessed higher than similar nearby properties, consider appealing.

  4. Damage or Repairs Needed
    Structural issues or damage, such as those from flooding, can reduce your home's value. Document these to support your appeal.

  5. Declining Neighborhood Values
    Economic downturns or increased crime rates that lower property values should be reflected in your assessment.

  6. Excessive Appraisal Increases
    Unjustified significant value jumps, such as a 20% increase without market evidence, signal the need for an appeal.

  7. Incorrect Exemptions Applied
    Missing or improperly applied exemptions like homestead or disability can inflate your tax bill.

  8. Non-Uniform Appraisal
    If your home is assessed higher than similar area properties, it may violate Texas’ uniformity clause.

  9. Economic Hardship
    Financial challenges can justify a reassessment request to provide tax relief.

  10. Professional Valuation Disagreement
    A professional appraisal showing a lower value than your assessment is compelling evidence for an appeal.

  • Overvaluation of Your Property: Discrepancies between assessed and market values are valid appeal reasons.
  • Errors in Assessment: Incorrect details like square footage can inflate your tax bill.
  • Market Changes: Real estate market fluctuations should be reflected accurately in assessments.
