Rate Breakdown

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

How Property Tax Works in Washington County

Property taxes in Washington County, Missouri, are determined by a combination of the assessed value of your property and the local tax rate, often referred to as the millage rate. The assessment process begins with the County Assessor, who determines the market value of the property. In Missouri, the assessed value is typically a percentage of the market value: 19% for non-owner-occupied real property and 11.5% for owner-occupied residential property.

The millage rate is the tax rate set by local taxing districts, including the county, school districts, and municipalities. One mill represents one dollar of tax for every $1,000 of assessed valuation. Your total annual tax bill is calculated by multiplying your property's assessed value by the combined millage rates of all applicable jurisdictions.

Available Exemptions

Missouri offers several tax relief programs to reduce the financial burden on eligible homeowners. These exemptions lower the taxable value of the property, thereby reducing the final tax bill. Common exemptions include:

• Homestead Relief: Available to senior citizens (65+) and disabled residents who meet specific income requirements.
• Senior Citizen Tax Freeze: Allows eligible seniors to freeze the assessed value of their home, preventing tax increases as property values rise.
• Veterans Exemptions: Specific tax relief may be available for disabled veterans or surviving spouses of veterans.
• Agricultural Exemptions: Land used primarily for agricultural purposes may qualify for a lower assessment rate.

Payment Schedule & Deadlines

Property taxes in Washington County are typically billed annually, though payment structures can vary. It is critical to adhere to the deadlines set by the County Collector to avoid financial penalties.

• Payment Deadlines: While taxes are levied annually, payments are often due in installments or as a single lump sum. Check your specific tax notice for the exact due date.
• Installment Options: Some taxpayers may opt for installment payments to spread the cost across the year.
• Late Consequences: Failure to pay by the deadline results in the accrual of interest and potential penalties. Persistent delinquency may eventually lead to a tax sale of the property.

Appealing Your Assessment

If you believe your property has been overvalued by the County Assessor, you have the right to appeal the assessment. The process generally begins with filing a formal appeal application with the County Assessor's office during the designated appeal window, typically shortly after assessment notices are mailed.

During the appeal, you should provide evidence to support your claim, such as a recent independent appraisal, a list of comparable properties that sold for less, or documentation of property damage. If a resolution is not reached with the assessor, the case may be heard by a Board of Equalization or a circuit court.
