Rate Breakdown

Property taxes in Boone County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Boone County

Property taxes in Boone County are determined by two primary factors: the assessed value of your property and the local tax rate, often referred to as the millage rate. The Boone County Assessor’s Office is responsible for determining the "market value" of your real estate. By state law, residential property is assessed at 19% of its true market value, while agricultural property is assessed at 12% and commercial property at 32%.

Once the assessed value is established, it is multiplied by the combined tax levy rate of all applicable taxing districts—including the county, school districts, cities, and fire protection districts. These rates are expressed in dollars per $100 of assessed valuation. Because these levies are voted upon by the public to fund local services, your total tax bill reflects the specific combination of taxing jurisdictions in which your property is located.

Available Exemptions

Missouri offers several programs designed to provide tax relief for specific groups of property owners. Eligibility and application requirements vary, so it is recommended to verify status with the Boone County Assessor or the Missouri Department of Revenue.

• Senior Citizens and Disabled Persons: The Missouri Property Tax Credit (Circuit Breaker) provides a credit to eligible seniors and individuals with disabilities for a portion of the real estate taxes paid on their primary residence.
• Veterans: Missouri provides a 100% exemption on real and personal property taxes for veterans who are 100% service-connected disabled.
• Homestead Exemption: While Missouri does not have a traditional "homestead exemption" that lowers the assessed value of a home, the state does implement a "Senior Property Tax Credit" (Senate Bill 190) which allows eligible seniors to freeze their property tax liability at the amount paid in the year they become eligible.

Payment Schedule & Deadlines

Property tax bills in Boone County are mailed annually, typically in November. Payment is due by December 31 of the tax year. To avoid penalties, payments must be postmarked or received by this date.

If you fail to pay your property taxes by the December 31 deadline, the county will apply interest and penalties that accrue monthly. Continued delinquency may result in your property being placed on the delinquent tax list, which can eventually lead to a tax sale. Boone County does not currently offer a standard installment plan for current-year property taxes; therefore, the full balance must be paid by the end of the calendar year.

Appealing Your Assessment

If you believe the market value assigned to your property is inaccurate, you have the right to appeal. The process typically begins with an informal review by the Boone County Assessor’s Office. If you remain dissatisfied, you may file a formal appeal with the Boone County Board of Equalization. Should the issue remain unresolved, you may further appeal to the Missouri State Tax Commission. It is essential to provide documentation, such as recent appraisals or comparable sales data, to support your claim during these proceedings.
