Property tax protest

Most homeowners never challenge their property tax assessment, yet studies and industry data consistently show that 30—60% of properties are over-assessed. Among those who do file a protest, success rates are remarkably high:

1. Review Your Assessment Notice

  • Your county or municipality mails a Notice of Assessed/Appraised Value annually (timing varies by state — see table below).
  • Verify every factual detail: square footage, lot size, number of bedrooms/bathrooms, year built, construction type, condition rating.
  • Errors are common. A wrong bedroom count or inflated square footage can add thousands to your assessed value.
  • Compare the assessed value to what you believe your home would actually sell for on the open market.

2. Research Comparable Sales (Comps)

  • Find 3—5 recent sales of similar homes in your area (ideally within 0.5 miles and sold in the last 6—12 months).
  • Match on: square footage, age, condition, lot size, bedroom/bathroom count, school district.
  • Sources: Zillow, Realtor.com, Redfin, your county appraisal district website, MLS data (via a real estate agent).
  • Calculate the price per square foot for each comp and compare to your assessed value per square foot.
  • Also pull the assessed values of comparable properties from your county assessor's website — if neighbors with similar homes are assessed lower, that is strong "unequal appraisal" evidence.

3. Document Property Condition Issues

  • Photograph any defects: roof damage, foundation cracks, outdated systems (HVAC, plumbing, electrical), flood damage, mold, needed repairs.
  • Obtain repair estimates or contractor bids for significant issues.
  • Note any negative externalities: proximity to highways, commercial zones, power lines, flood zones, noise sources.

4. File Your Protest Before the Deadline

  • File the official protest form with your county/local appraisal review board. Most jurisdictions now offer online filing.
  • You do not need to state your full case at filing — just indicate you are protesting the value.
  • Common grounds for protest:
  • Market value: Assessed value exceeds fair market value.
  • Unequal appraisal: Your property is assessed higher than comparable properties.
  • Errors in property description: Incorrect square footage, room counts, etc.
  • File early. Online systems crash near deadlines, and early filers often get earlier hearing dates.

5. Attend the Informal Hearing (If Offered)

  • Many jurisdictions offer an informal settlement conference with an appraiser before the formal hearing.
  • This is where most protests are resolved — the appraiser reviews your evidence and may agree to a reduction on the spot.
  • Bring all your evidence (comps, photos, repair estimates) organized clearly.
  • Be polite, factual, and concise. This is a negotiation, not a courtroom.

6. Attend the Formal Hearing (Appraisal Review Board / Board of Equalization)

  • If the informal hearing does not resolve your protest, you proceed to a formal hearing before a panel.
  • Present your evidence systematically: state your opinion of value, show comps, explain condition issues.
  • Bring 3+ extra copies of all evidence for board members.
  • Typical hearing length: 15—30 minutes.
  • The board will mail you a written decision.

7. Further Appeals (If Needed)

  • If you disagree with the board's decision, most states allow further appeal to:
  • Binding arbitration (often for properties under $5 million; small fee required).
  • State district court (formal legal proceeding; attorney recommended).
  • State Office of Administrative Hearings (available in some states for higher-value properties).
  • Further appeals must typically be filed within 30—60 days of the board's final order.

8. Comparable Sales (Most Important)

  • 3—5 sales of similar homes within 0.5 miles, sold in last 6—12 months
  • Property details for each comp: address, sale price, square footage, lot size, bedrooms, bathrooms, year built, condition
  • Price-per-square-foot calculation for each comp vs. your property
  • Source documentation (MLS listings, county records, Zillow screenshots)
  • Map showing proximity of comps to your property

9. Unequal Appraisal Evidence

  • Assessed values of 3—5 comparable neighboring properties from county records
  • Assessed-value-per-square-foot comparison chart
  • Highlight any neighbors with similar homes assessed significantly lower

10. Property Condition Documentation

  • Exterior photos: front, back, both sides, street view
  • Interior photos of any defects or needed repairs
  • Contractor bids or repair estimates for significant issues
  • Documentation of: roof age/condition, foundation issues, outdated HVAC/plumbing/electrical, water damage, mold, structural problems
  • Flood zone designation (if applicable)
  • Environmental issues (noise, commercial adjacency, power lines)

11. Professional Documentation (Optional but Powerful)

  • Independent appraisal by a licensed appraiser ($300—$500 typical cost)
  • Survey or engineering report for structural issues
  • Real estate agent's CMA (Comparative Market Analysis) — often free

12. Administrative Records

  • Your Notice of Assessed/Appraised Value (with date received)
  • Property record card from county assessor (verify all details for errors)
  • Your filed protest form (keep a copy)
  • Prior year assessment values (to show trend)
  • Any correspondence with the assessor's office

Common Mistakes

  • Missing the deadline
  • Not filing because "it won't work."
  • Arguing emotions instead of evidence
  • Using poor comparable sales
  • Not checking the property record card for errors

Pro Tips

  • Protest every single year
  • File on multiple grounds
  • Use the assessor's own data against them
  • Request your property record card
  • Photograph your property on a bad day
