Step-by-Step Missouri Appeal Process
Review Your Assessment Notice
Your assessment notice shows your property's taxable value. Look for the "assessed value" or "market value" – this is what you're appealing. Compare it to recent sales of similar homes in your neighborhood.
Gather Compelling Evidence
The - First level: County Board of Equalization wants to see hard data, not opinions. Focus on:
- •Comparable sales: 3-5 similar properties that sold for less than your assessed value
- •Property condition: Photos and repair estimates documenting any issues
- •Assessment errors: Wrong square footage, features, or lot size
- •Market analysis: Evidence of declining values in your area
File Your Appeal Application
Submit your appeal to the - First level: County Board of Equalization before the deadline. Most Missouri counties now offer online filing, but some still require paper forms. Include all your evidence with the initial filing when possible.
Prepare Your Presentation
If your appeal goes to a hearing, you'll typically have 5-15 minutes to present. Organize your evidence clearly, practice your key points, and prepare to answer questions about your property value.
Attend Your Hearing
Present your evidence professionally and stick to facts about market value. The board members are usually reasonable people – they just need solid evidence to justify a reduction.
What Makes Missouri's Appeal Process Unique
Missouri's patchwork of local senior freeze programs creates dramatic inequities across municipal borders. St. Louis City and County set the qualifying age at 62, while neighboring counties require 65, meaning a 63-year-old moving across county lines loses freeze eligibility. These programs freeze the tax amount, not the assessment, creating confusion when reassessments show higher values but frozen tax bills.
The state's "September 30 or 30 days after Board decision, whichever is later" deadline is uniquely flexible but creates a trap. Property owners who skip the Board of Equalization must still file by September 30, while those who go through the Board might have until late October or November. This encourages Board participation but can mislead those who think they have more time. Missouri's option to pay taxes under protest while appealing is more generous than many states that require full payment regardless of appeal status.
Assessment Cap/Protection
Missouri has no statewide assessment cap but offers local senior freezes:
- Property Tax Credit: Up to $1,100 for owners, $750 for renters (income-based)
- Senior freeze programs: Available in some counties/cities (varies)
- Age requirement: Typically 62-65 depending on locality
- Freezes tax amount, not assessed value
No general limitation on assessment increases.
Required Filing Form
- County level: Forms vary by county
- State level: Complaint for Review of Assessment (Form 470)
- Available from county assessor or stc.mo.gov

Common Missouri Appeal Mistakes to Avoid
❌ Missing the deadline

❌ Using weak comparables
Properties must be truly similar – same neighborhood, size, age, and condition
❌ Being unprepared
Board members ask questions. Know your evidence inside and out
❌ Getting emotional
Stay professional and factual. The board responds to data, not frustration
❌ Giving up after denial
Many successful appeals happen at the state level after local denial

Missouri Tax-Saving Strategies Beyond the Appeal
A successful appeal is just one way to lower your Missouri property taxes. These additional strategies can stack with your appeal for maximum savings.
Strategy 1: Appeal in the Reassessment Year (Odd Years)
Missouri reassesses in odd years only. The value set in 2025 applies to 2025-2026 taxes. Your appeal window is the second Monday in July in the reassessment year. In even years (2026), you can only appeal clerical errors.
Strategy 2: Claim the Property Tax Credit ($750-$1,100)
Seniors 65+ and disabled with income under $30,000 (single) / $34,000 (married) can receive up to $1,100 (homeowners) or $750 (renters). Filed on Form MO-PTC with your Missouri income tax return.
Strategy 3: Verify Your Property Classification
Missouri assesses residential at 19%, agricultural at 12%, commercial at 32%. If your property is misclassified as commercial when it's residential, you're paying 68% more in assessments. Check your classification.
Strategy 4: Apply for Assessment Freeze
Missouri offers an assessment freeze for qualifying seniors 62+ at the county level. Availability and specifics vary by county. Contact your county assessor.
Strategy 5: Understand the Hancock Amendment
Missouri's Hancock Amendment limits tax revenue growth to the rate of personal income growth. If assessments increase beyond this rate, rates must roll back. This provides structural protection, but you still benefit from individually lowering your assessment.
2026 Missouri Law Changes Affecting Your Appeal
Recent legislative changes in Missouri may affect your property tax bill and appeal strategy.
Biennial Reassessment (Odd Years)
Missouri reassesses all property in odd-numbered years. Your 2025 reassessment applies to 2025 and 2026 taxes. In even years (like 2026), your assessed value generally stays the same unless you've made improvements. This means your appeal window for the current assessment was in 2025 -- but you can appeal clerical errors or appeal the 2027 reassessment.
19% Residential Assessment Ratio
Missouri assesses residential property at 19% of market value (agricultural at 12%, commercial at 32%). A $200,000 home has an assessed value of $38,000. The ratio difference between property types is significant -- make sure your property is classified correctly.
Missouri Property Tax Credit (Circuit Breaker)
The Missouri Property Tax Credit provides relief for seniors and disabled persons:
- Age 65+ or disabled
- Income limit: $30,000 (single) / $34,000 (married)
- Credit: up to $750 (renters) or $1,100 (homeowners)
- Claimed on your Missouri income tax return (Form MO-PTC)
Hancock Amendment
Missouri's Hancock Amendment (1980) limits state and local tax revenue growth to the rate of personal income growth. If assessments increase beyond this rate, tax rates must be rolled back. This provides structural protection against runaway property tax growth at the local level.
Senior Assessment Freeze
Missouri offers an assessment freeze for qualifying seniors 62+ at the county level. Eligibility and specifics vary by county. Contact your county assessor to see if a freeze is available in your jurisdiction.
