Missouri Property Tax Law Changes 2026: What Homeowners Need to Know

Updated March 2026

Key Takeaway

Missouri reassesses in odd years only and uses a 19% assessment ratio for residential property. The state offers a Property Tax Credit (Circuit Breaker) of up to $750-$1,100 for seniors 65+ with incomes under $30,000-$34,000. The Hancock Amendment limits tax revenue growth. Appeals are filed by the second Monday in July in even years.

Missouri Property Tax Snapshot: 2026

Average annual tax: $1,587
Effective tax rate: 0.97%
Assessment ratio: 19% of market value
Reassessment cycle: biennial (odd years)

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.
