Rate Breakdown

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

How Property Tax Works in Saint Louis County

Property taxes in Saint Louis County are based on the "assessed value" of a property, which is a percentage of its fair market value. In Missouri, residential properties are typically assessed at 19% of their market value. The County Assessor determines this value based on comparable sales and property characteristics.

Once the assessed value is established, the local taxing authorities apply a "millage rate" to calculate the final tax bill. A mill is equal to $1 for every $1,000 of assessed value. Your total tax burden is the sum of rates from various entities, including the county, city, school districts, and special taxing districts (such as fire or sewer).

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 overall tax bill:

• Homestead Exemption: Available to homeowners who occupy the property as their primary residence.
• Senior Citizen Tax Relief: Residents 65 and older may qualify for a freeze on assessed value or a reduction in taxes based on income levels.
• Disability Exemptions: Specific tax relief is available for individuals with permanent total disabilities.
• Veteran Exemptions: Disabled veterans may be eligible for significant property tax exemptions depending on their level of service-connected disability.

Payment Schedule & Deadlines

Property taxes in Saint Louis County are typically billed annually, but the payment structure can vary. Most taxpayers have the option to pay in a single lump sum or through two semi-annual installments.

• Deadlines: Tax bills are generally mailed in the fall. Payments are typically due by December 31st to avoid interest, though specific deadlines may vary by municipality.
• Installments: If paying in installments, ensure the first half is paid by the fall deadline and the second half by the spring deadline.
• Late Consequences: Payments made after the deadline are subject to statutory interest charges and penalties. Delinquent accounts may eventually lead to a tax lien or a public tax sale.

Appealing Your Assessment

If you believe your property's assessed value is incorrect or exceeds the current market value, you have the right to appeal. The process generally begins with filing an application for review with the Saint Louis County Board of Equalization (BOE).

To successfully appeal, homeowners should gather evidence, such as a recent independent appraisal or a list of comparable properties in the neighborhood that have sold for less than the assessed value. Appeals must be filed within a specific window—usually shortly after the assessment notice is mailed—to be considered for the current tax year.
