Critical Warning
Property tax appeals can save you thousands, but common mistakes can doom even the strongest cases. Here are the pitfalls that trip up most homeowners—and how to avoid them.
Every year, thousands of property owners file appeals to reduce their tax bills. Unfortunately, many of these appeals fail—not because they lack merit, but because of preventable mistakes that undermine otherwise strong cases.
Success by the Numbers
When done correctly, property tax appeals succeed 40-84% of the time, saving homeowners an average of $1,200-3,000 annually. The difference between success and failure often comes down to avoiding these critical mistakes.
Mistake #1: Missing the Appeal Deadline
The Problem
Most counties have strict deadlines—typically 30-45 days after receiving your assessment notice. Miss this window, and you're stuck with your current assessment for another year.
The Fix:
- Mark your calendar immediately when you receive your assessment notice
- Set multiple reminders leading up to the deadline
- Start the appeal process early—don't wait until the last minute
- Know your county's specific rules and deadlines
Mistake #2: Using Poor Comparable Sales
The Problem
Many homeowners select random "sold" properties without considering size, condition, location, or sale date. Weak comparables destroy your credibility with assessors.
The Fix:
- Use sales within the last 12-18 months
- Find properties within 0.5 miles of your home
- Match square footage within 20% (+/- 200-400 sq ft)
- Select similar age, style, and condition properties
- Aim for 3-5 strong comparables, not 10+ weak ones
Mistake #3: Failing to Document Property Defects
The Problem
Homeowners mention issues like "old roof" or "needs updating" without providing evidence. Assessors need proof, not just your word.
The Fix:
- Take high-quality photos of all defects and problem areas
- Get repair estimates from licensed contractors
- Document the age of major systems (HVAC, roof, plumbing)
- Note any health/safety issues or code violations
- Organize evidence clearly and professionally
Mistake #4: Ignoring Assessment Data Errors
The Problem
Many appeals focus solely on market value while ignoring factual errors in the property record card that can provide easier wins.
The Fix:
- Obtain and carefully review your property record card
- Measure your actual square footage
- Verify room counts, bathroom counts, and other features
- Check lot size, year built, and condition ratings
- Document any discrepancies with photos and measurements
Mistake #5: Making Emotional or Irrelevant Arguments
The Problem
Appeals citing "high taxes," "can't afford it," or "neighbor disputes" fail because assessors can only consider property value—not personal circumstances.
The Fix:
- Focus only on property value and assessment accuracy
- Present facts and data, not opinions or emotions
- Use objective evidence like sales data and condition reports
- Avoid mentioning personal financial situations
- Keep your argument professional and evidence-based
Mistake #6: Poor Presentation and Organization
The Problem
Messy, handwritten appeals with poor photos and disorganized information are hard to follow and appear unprofessional to assessors.
The Fix:
- Create a clear, typed executive summary
- Organize evidence with section headers and page numbers
- Use high-quality, well-lit photographs
- Include a table of comparable sales with key details
- Proofread everything before submitting

Mistake #7: Not Understanding Local Assessment Practices
The Problem
Different counties use different assessment methods, appeal procedures, and deadlines. A one-size-fits-all approach often fails.
The Fix:
- Research your county's specific assessment methodology
- Understand their appeal process and requirements
- Know what evidence they find most convincing
- Learn about recent successful appeals in your area
- Consider professional help if the process is complex
