Required Documentation for a Successful Appeal

To file a successful property tax appeal in Texas, including Houston, you’ll need to gather the right documentation to support your case. Missing or incomplete documents can delay or weaken your appeal, so preparation is key. Here’s what you need:

Essential Documents for Your Appeal

1. Property Tax Notice: Your official notice from the Harris County Appraisal District (HCAD) or your local appraisal district, which includes your property’s assessed value and deadline to file.
2. Evidence of Comparable Properties: Provide recent sales data of similar homes in your area to show your property is overvalued. Use HCAD’s online tools or platforms like TaxLasso to quickly find accurate comps.
3. Photos of Your Property: Highlight any issues (e.g., structural damage, outdated features) that could lower your home’s value.
4. Repair Estimates or Appraisals: If your property has significant issues, include repair estimates or a professional appraisal to justify a lower valuation.
5. Income and Expense Statements (for rental properties): If you own rental property, provide income and expense records to prove lower profitability.

What Happens If You Miss the Deadline?

If you miss the property tax appeal deadline in Texas, you lose the opportunity to challenge your property tax valuation for that year. This means you’ll have to pay the assessed taxes without any chance of reducing your bill, potentially costing you hundreds or thousands of dollars.

Key Consequences of Missing the Deadline:

• No Appeal for the Current Year: Once the deadline passes (typically May 15 or 30 days after you receive your appraisal notice, whichever is later), you cannot appeal your property tax valuation for that tax year.
• Higher Tax Bills: Without a successful appeal, you’ll pay the full assessed amount, which could be significantly higher than what your property is actually worth.
• No Refunds: Even if you later prove your property was overvalued, you won’t receive a refund for overpaid taxes.

How to Avoid Missing Deadlines:

• Set Reminders: Use digital calendars or apps to track the deadline.
• Act Early: Start the appeal process as soon as you receive your appraisal notice.
• Use TaxLasso: TaxLasso simplifies the process, allowing you to file a professional-level appeal in just 5 minutes. Unlike DIY methods, which can take hours, or legal firms, which can cost thousands, TaxLasso offers an affordable, efficient solution that puts you in control.

Don’t risk overpaying on your property taxes. Take action before the deadline to ensure you have the best chance of lowering your tax bill.
