Thinking of moving to St Louis County, MO? You must get a handle on the local property tax rates if you’re considering buying a home. Property taxes can get complex and confusing, but it’s essential to understand your financial obligations. To help you make sense of the costs associated with homeownership, here is an in-depth look at how to pay property taxes in St Louis County. 

St Louis County Property Taxes

Property tax is a fee collected by the local government to pay for municipal services such as public schools, sewage, senior services, libraries, or zoos. St Louis county assesses an annual tax on all property including real estate and personal property such as motor vehicles and boats. 

In the state of Missouri, political subdivisions such as school districts and library zones have the power to set tax rates. Other special districts and programs within a particular city may add to your annual tax bill.

Property tax rates are assessed at a certain percentage of the assessed value. The County Assessor is the party responsible for determining the assessed value of a property. Every two years, the assessor will do a county-wide valuation of property, which is added to the official assessment roll.

The assessor calculates the market value of a property based on factors such as recent sales data and other trends. They will then take a percentage of the market value to arrive at the assessed value or the amount that can be taxed. The rate will depend on the classification of the property and how it’s used. They will then multiply the assessed value by the rate set by the various political subdivisions to calculate what is owed. 

The Collector of Revenue is responsible for the billing and collection of property taxes in St Louis County. They collect the assessment roll from the Assessor and use it to create bills to send to homeowners. They are also responsible for collecting the funds and dispersing them to the various districts and agencies that will use them.

How are Tax Rates Determined in St Louis County?

The total St Louis County property tax rate is a composite of different tax rates set by the local districts in which the property is located. For instance, there is a separate rate for each library, school, sewage, fire, and lights district as well as the county and local municipality. These tax rates are determined by the local political district levying the tax and are applied to the assessed value of the property. The tax rate is typically expressed as a rate per $100 in assessed value.

How to Calculate Assessed Value?

The assessed value for residential real estate in St Louis County is 19% of the market value. So, if the home is valued at $100,000, the assessed value is $19,000. St Louis County personal property tax rates are available on their website. They publish their annual rate book so you can see the rates set by each school and political district every year. If you want to learn how to find out real property tax in St Louis County, look at the rate book and find all districts that cover the property, add them all together, and multiply that rate by the assessed value of the home.

According to the St Louis County Collector of Revenue, the $2.4 billion in tax revenue collected annually is dispersed according to the following:

  • 53.81% of school districts
  • 15.72% to community colleges

  • 9.63% to other services (libraries, zoos, etc.)
  • 5.66% to state municipal services
  • 5.15% to St Louis County

Also, be aware that you have the right to appeal the assessed value of your home if you believe your tax rate is too high. The county assessor recalculates marker value every two years, although it’s possible that conditions have changed or they made a mistake.

St Louis County Property Tax Rate Example – Eureka Property Tax Rate

Since many different factors impact St Louis County property tax rates, it’s difficult to determine a fair estimate without all the necessary information.

To make the information easier to understand, let’s take a look at the city of Eureka, Missouri as an example. Eureka is a small city in St Louis County with a population of about 11,646 people. According to the City of Eureka government website, the total tax rate in the city is 8.0308 per $100 of assessed value. 

Here are the rates charged by each district:

  • City of Eureka: 0.2970
  • Eureka Fire Protection District: 1.2805
  • Metropolitan Zoo/Museum District: 0.2528
  • Road & Bridge: 0.0830
  • Rockwood School District: 4.1483
  • Dev. Disability Productive Living Board: 0.0700
  • St. Louis Community College: 0.2787
  • St. Louis County Bond Retirement: 0.0190
  • St. Louis County General: 0.1650
  • St. Louis County Health Fund: 0.1110
  • St. Louis County Library: 0.2060
  • St. Louis County Park Maintenance: 0.0400
  • State of Missouri: 0.0300

Total: 8.0308 per $100 of assessed value.


According to Redfin, the Eureka median sales price of a home is $345,604. Based on that number, the median assessed value would be around $65,665. At a rate of 8.0308 per $100, your annual tax bill would be around $5,273.41

Market value ($345,604) x assessed rate (0.19) x tax rate (0.080308) = $5,273.41

If you want to calculate the tax rate for another city in St Louis County, use the rate book and swap/add any political districts that apply (such as school district, fire, city, etc.). Then use the same formula to calculate the assessed value and apply it to the new rate.
