Types of Tax Appeals

When it comes to property tax appeals in Houston, homeowners have several options to challenge their assessments. Understanding the types of tax appeals available can help you take the right action to potentially lower your property tax bill.

1. Informal Appeal (Appraisal Review Board - ARB)

  • This is the most common type of appeal for Houston homeowners.
  • You present evidence (e.g., comparable property values, photos, or repair estimates) to the ARB to argue your property is overvalued.
  • Deadlines: Appeals must be filed by May 15, 2025, or 30 days after receiving your appraisal notice, whichever is later.
  • Why it matters: Over 50% of informal appeals in Harris County result in reduced valuations.

2. Formal Appeal (Binding Arbitration or District Court)

  • If the ARB denies your informal appeal, you can escalate to binding arbitration or district court.
  • Arbitration is cost-effective (filing fees start at $500) but requires strong evidence.
  • District court is more expensive and time-consuming, often involving legal representation.
  • Why it matters: Formal appeals are best for high-value properties or complex cases.

3. Online Property Tax Appeal

  • Platforms like TaxLasso simplify the process by handling evidence gathering, filing, and follow-ups for you.
  • Why it’s superior:
    • DIY comparison: TaxLasso takes just 5 minutes instead of hours, providing professional-level insights.
    • Legal firm comparison: Save thousands of dollars while maintaining full control over your appeal.

Key Considerations for 2025

  • Houston property values are expected to rise, making appeals even more critical.
  • Act early: Filing deadlines are strict, and delays can cost you savings.

By choosing the right type of appeal and leveraging tools like TaxLasso, Houston homeowners can save time, money, and stress while ensuring their property taxes are fair.

Missing these deadlines means you’ll have to wait until the next tax year to appeal.

Evidence That Wins Appeals & Common Reasons for Success

When appealing your property tax assessment in Houston, the key to success lies in presenting strong, actionable evidence. The most common reasons for winning appeals include inaccurate property valuations, comparables that support a lower value, and errors in the appraisal district’s data. Here’s what you need to know:

Evidence That Wins Appeals

  • Comparable Sales (Comps): Provide recent sales data (within the last 6-12 months) of similar properties in your neighborhood. For example, if your home is valued at $400,000 but nearby homes with similar features sold for $350,000, this is compelling evidence.
  • Condition of Your Property: Document issues like foundation problems, outdated systems, or needed repairs that reduce your home’s value. Photos and contractor estimates strengthen your case.
  • Appraisal District Errors: Review your property record for mistakes in square footage, room count, or lot size. In 2025, Houston homeowners can access updated records online to verify accuracy.

Common Reasons for Success

  1. Overvaluation: If your home’s assessed value exceeds its market value, comps and appraisals can prove this.
  2. Unequal Appraisal: If similar homes are taxed at a lower rate, this is grounds for appeal.
  3. Data Errors: Mistakes in property details are common and often lead to successful appeals.
