Your property record card (also called property data card) contains the assessor's information about your property. Obtain this from your assessor's website or office.
Review for factual errors:
Data Point
Verify Against
Common Errors
Square footage
Your own measurement or survey
Overstated living area, including unfinished space
Lot size
Survey or deed
Incorrect acreage or lot dimensions
Bedroom count
Physical count
Counting offices or bonus rooms as bedrooms
Bathroom count
Physical count
Incorrect half/full bath count
Year built
Actual records
Wrong year affecting depreciation calculations
Construction quality
Visual assessment
Rated as higher grade than actual
Condition
Visual assessment
Not reflecting deferred maintenance or issues
Basement
Physical assessment
Counting unfinished as finished space
Garage
Physical assessment
Wrong size or type
Amenities
Physical assessment
Listing amenities that do not exist (pool, fireplace)
Factual errors are the easiest appeals to win. If your property card has incorrect data, the assessor often corrects without a formal hearing.
Phase 3: Grounds for Appeal
Common Grounds for Reduction
1. Factual Errors (Strongest Ground) Property record contains incorrect physical data (square footage, room count, lot size, features).
2. Market Value Overstatement The assessed value exceeds what the property would sell for in the current market.
3. Uniformity / Equity Your property is assessed at a higher percentage of market value than comparable neighboring properties (unequal treatment).
4. Recent Purchase Below Assessed Value You purchased the property for less than the assessed value in an arm's-length transaction (strongest evidence of market value).
5. Physical Condition Issues
Structural deficiencies
Environmental contamination
Flooding or drainage problems
Code violations requiring expensive remediation
Deferred maintenance reducing value
6. External Obsolescence Value-reducing factors outside your property:
Proximity to commercial or industrial use
Traffic noise, highway proximity
Power lines or cell towers nearby
Environmental hazards in neighborhood
Declining neighborhood conditions
Nearby foreclosures or distressed sales
7. Functional Obsolescence Layout or design features that reduce value:
Outdated floor plan
Bedroom accessible only through another bedroom
No first-floor bathroom
Inadequate electrical or plumbing systems
Over-improvement for the neighborhood
Phase 4: Comparable Property Research
Finding Comparable Properties
Sources for comparable data:
County assessor's website (assessed values of all properties are public record)
MLS data (ask a real estate agent or use public records)
Zillow, Redfin, Realtor.com (recent sales)
County recorder's office (deed transfer records)
Comparable Selection Criteria
Select 3-6 comparable properties that:
Are in the same neighborhood or assessment district
Sold within the last 6-12 months (recent sales carry more weight)
Are similar in size, age, style, and condition
Have similar lot sizes and features
Are assessed at a lower value relative to their market value
Market Value Approach: "My property is assessed at $300,000 but comparable sales show it is worth only $260,000."
Equity Approach: "My property is assessed at a higher percentage of market value than similar neighboring properties, violating the principle of uniform assessment."
You can use one or both approaches in your appeal.
Many errors and minor overassessments are resolved here
No formal hearing, usually a conversation or meeting
Always try this first
Level 2: Local Board of Review / Board of Equalization
Formal hearing before a local review board
Present your evidence and argument
Board members may ask questions
Decision typically binding unless appealed further
Most common formal appeal level
Level 3: State Tax Tribunal / Board of Tax Appeals
More formal proceeding
May involve legal representation
Longer timeline
For significant disputes or when local board decision seems wrong
Level 4: Court (Tax Court or Circuit Court)
Last resort
Requires legal representation
Expensive and time-consuming
Only for large amounts or matters of principle
Phase 7: Hearing Preparation
Presentation Tips
Do:
Be organized, professional, and respectful
Present facts and data, not emotions
Focus on comparable properties and documented evidence
Know your property's details thoroughly
Practice your presentation (aim for 5-10 minutes)
Bring copies of all evidence for board members
Address potential counterarguments proactively
Thank the board for their time
Do Not:
Complain about the tax rate or how taxes are spent
Compare your property to non-comparable properties
Make emotional arguments ("I can't afford my taxes")
Be confrontational or adversarial
Present incomplete or inaccurate data
Ramble or go off-topic
Argue about how much you owe -- argue about assessed VALUE

Phase 8: Cost-Benefit Analysis
Is It Worth Appealing?
APPEAL COST-BENEFIT ANALYSIS
=============================
Current Assessed Value: $__________
Your Proposed Assessed Value: $__________
Difference: $__________
Current Annual Tax: $__________
Tax at Proposed Value: $__________
Potential Annual Savings: $__________
Appeal Costs:
Filing Fee: $__________
Appraisal (if getting one): $__________

Your Time (hours x your rate): $__________
Total Appeal Cost: $__________
Break-Even Analysis:
Years to Recoup Costs: Total Cost / Annual Savings = _____ years
5-Year Net Savings: (Annual Savings x 5) - Total Cost = $__________
When Appealing Makes the Most Sense
Factual errors exist on your property record card
Assessment is 10%+ above likely market value
You purchased recently for less than assessed value
Potential annual savings exceed $500
You have good comparable evidence
Your property has documented condition issues
When It May Not Be Worth Appealing
Assessment is within 5% of market value
Potential savings are under $200/year
You have no comparable evidence
Property has been recently improved and value increase is justified
The cost of professional help exceeds several years of savings
Professional Help: When to Hire
Property tax attorney or consultant:
For assessed values over $500,000
Complex commercial properties
When potential savings exceed $2,000/year
Multi-property portfolios
When you are uncomfortable presenting your own case
For state tribunal or court appeals
Most property tax professionals work on contingency (25-50% of first year's savings), making the financial risk low.
Exemptions and Credits to Verify
Before or in addition to appealing your assessed value, verify you are receiving all available exemptions:
Veteran exemption (service-connected disability often increases benefit)
☐To do:
Disability exemption
☐To do:
Agricultural use exemption (if applicable)
☐To do:
Historic property exemption
☐To do:
Solar/renewable energy exemption
☐To do:
Circuit breaker / property tax cap programs
☐To do:
State-specific programs (research your state)
Unclaimed exemptions can save as much or more than a successful appeal, and are often much easier to obtain.
Annual Assessment Monitoring
After your appeal (whether successful or not), continue monitoring:
Review your assessment notice every year when it arrives
Track comparable sales in your neighborhood
Note any changes that might affect value (positive or negative)
Keep your appeal evidence updated for potential future appeals
Mark appeal deadlines on your calendar each year
Property tax assessment is not a one-time event. Market conditions change, assessment methods evolve, and errors can occur at any reassessment. Stay informed and proactive.

Conflicting requirements: Identify trade-offs explicitly and present options with pros and cons
Scale mismatch: Adapt recommendations to match the user's context (individual vs. team vs. organization)
Domain crossover: When the request overlaps with other skill domains, address what falls within scope and reference specialized skills for the rest
