7 Legitimate Reasons to Protest Property Taxes (And How to Win Your Case)

Property taxes can feel overwhelming, but you don’t have to accept an unfair bill. If your 2025 property appraisal seems too high or doesn’t reflect your home’s true value, you have every right to protest—and win. For Houston homeowners, where rising property values often lead to higher taxes, knowing your rights and options is crucial. This article outlines seven legitimate reasons to protest your property taxes, from incorrect appraisal data to unequal assessments, and provides actionable steps to build a strong case. Whether you’re considering a DIY approach, hiring a law firm, or using a streamlined service like TaxLasso—which takes just 5 minutes and costs far less than traditional options—you’ll learn how to fight back effectively and save money.

7 Legally Valid Reasons to Protest Your Property Appraisal

If you believe your property appraisal is inaccurate or unfair, you have the legal right to protest. Here are seven valid reasons to challenge your appraisal and potentially lower your property taxes:

  1. Incorrect Property Details
    Incorrect details like wrong square footage or room counts provide a strong basis for protest. For instance, prove discrepancies with evidence if your home is listed incorrectly.

  2. Overvalued Market Value
    Compare your appraisal with recent sales of similar homes in your Houston neighborhood. If your appraisal exceeds the fair market value, you have a valid case.

  3. Unequal Appraisal
    Texas law requires uniform appraisals. If your property is valued higher than similar properties, you can protest.

  4. Damage or Structural Issues
    Present documentation of any unrepaired damage to argue for a lower valuation.

  5. Declining Market Conditions
    Use neighborhood economic declines as evidence for a reduced appraisal.

  6. Exemptions Not Applied
    Ensure all applicable exemptions are applied to avoid inflated taxable values.

  7. Recent Appraisal Errors
    If your appraisal increased significantly without justification, gather evidence to contest it.

Protesting your appraisal can save you thousands, but the process can be time-consuming. TaxLasso simplifies this by providing professional-level insights in just 5 minutes—far faster than DIY methods—and at a fraction of the cost of hiring a legal firm.

How to Prove Your Property Is Overassessed

Proving your property is overassessed is the first step to lowering your property taxes. In Houston, where property values can fluctuate significantly, it’s crucial to gather evidence that supports your claim. Here’s how to do it effectively:

  1. Compare Your Property to Similar Homes
    Obtain the appraisal district’s assessed value of your property and research recent sales of comparable homes. If your assessed value is higher, you have strong evidence.

  2. Check for Errors in Your Property Description
    Look for inaccuracies in your property’s details. If errors exist, this could lead to an inflated valuation.

  3. Document Property Issues
    Gather evidence of issues that reduce your property’s value, such as structural problems or outdated systems.

  4. Use Professional Tools for Accurate Comparisons
    Utilize tools like TaxLasso to generate professional-level property valuations quickly.

  5. Submit Your Evidence During the Protest Process
    File a protest with the Harris County Appraisal District by the deadline. Include evidence to support your case.

By taking these steps, you can confidently prove your property is overassessed and secure a fair valuation.

Common Assessor Mistakes to Leverage

Assessors often make errors that can lead to inflated property valuations, giving Houston homeowners a strong reason to protest. By identifying these mistakes, you can significantly reduce your property tax burden. Here are the most common assessor errors to watch for:

  1. Incorrect Property Details
    Ensure accuracy in square footage and property type. Gather evidence like floor plans to support your protest.

  2. Overvalued Comparable Sales
    Verify that the comps used are appropriate. Research similar homes in your area.

  3. Failure to Account for Depreciation or Damage
    Document any issues with photos or repair estimates.

  4. Mathematical Errors
    Double-check calculations on your appraisal notice, especially if your property’s value increased significantly.

Instead of spending hours researching comps or paying thousands to a legal firm, TaxLasso offers a 5-minute solution. It combines the affordability of DIY with professional expertise, ensuring you get the best results.

Required Documentation for a Successful Protest

  3. Photos of Property Issues
    Document issues that lower your home’s value.
