How Assessment Works in Missouri
Missouri assesses residential property at 19% of true value (market value). Agricultural property is assessed at 12% and commercial at 32%. Your tax bill is based on the assessed value, not the full market value.
Risk of Increase
In Missouri, filing a appeal can result in your assessed value being increased. This is uncommon when you have strong evidence of over-assessment, but you should be aware of this possibility. ProtestMax only recommends filing when our analysis shows a clear case for reduction.
How to File in Missouri
File an appeal with your county Board of Equalization during the open appeal period (typically July through the second Monday in August in reassessment years). You may also appeal informally to the county assessor.

FAQ
Missouri Property Tax Appeal Questions
How does the 19% ratio work in Missouri?
If your home's true value is $250,000, the assessed value is $47,500 (19%). Your tax bill is this assessed value multiplied by your local tax rate.
Can my Missouri assessment increase on appeal?
Yes. The Board of Equalization can increase your assessment. However, increases are rare when you present clear evidence of over-assessment.
How often does Missouri reassess?
Missouri reassesses all property every two years (odd-numbered years). In between reassessment years, values generally remain the same unless there are physical changes to the property.
