Learn how to appeal your property tax assessment and potentially save $500-$3,000 per year. Free property tax appeal guide by state.
30-60% of property tax assessments contain errors — and most homeowners never challenge them. A successful property tax appeal saves $500-$3,000 per year, every year. The process is designed to be accessible to homeowners without lawyers and takes 2-4 hours of preparation for a potential years-long annual savings.
Step 1: Request your property assessment card from assessor's office — verify square footage, bedroom count, and features are correct. Step 2: Research 5-6 comparable recent sales (comps) in your neighborhood of similar size, age, and condition. Step 3: Calculate the implied value your assessment represents versus comparable sales prices. Step 4: Document any issues reducing your home's value (needed repairs, location factors). Step 5: File the appeal before your jurisdiction's deadline — typically 30-90 days after assessment notice.
Appeal statistics: Nationally homeowners who appeal are successful 50-60% of the time. Average annual tax savings from successful appeal: $700-$2,500 depending on property value and market. The reduction applies every year until the next reassessment. No downside to filing an appeal — assessments are never raised because you appealed. Professional property tax consultants exist for complex cases and work on contingency.
Look up recent sales of comparable homes in your neighborhood on Zillow or Redfin. Divide your assessed value by the assessment ratio (your county's standard percentage of market value — find this on assessor's website). If the implied market value is significantly higher than comparable sales: you may be over-assessed. Also check: is your home's physical description (square footage, rooms) on the assessment card accurate?
Deadlines vary widely by jurisdiction: typically 30-90 days after the assessment notice is mailed. Some jurisdictions have fixed annual windows like April 1 to May 31. Missing the deadline means waiting until the next assessment cycle. Check your county assessor's website immediately upon receiving your assessment notice to find the exact deadline.
No — most informal hearings before the assessment review board are handled successfully by homeowners without lawyers. Bring your evidence: comps, photos of issues, and the assessment card with errors marked. If informal appeal fails you can escalate to a formal board hearing where a property tax attorney or consultant can increase success probability for higher-value cases.
