What is the property tax rate in St. Louis?

The effective combined property tax rate in the City of St. Louis is about 1.22% of a home's market value. That bundles the city, school, and other local levies into one effective figure.

How does Missouri's assessment ratio work?

Missouri taxes residential property on 19% of market value, not the full value. So a $250,000 home has an assessed value of $47,500, and the levy is applied to that assessed amount.

Why is my actual bill different from the estimate?

Exact bills depend on the year's specific levy rates, voter-approved bond issues, and any special taxing districts on your parcel. This tool uses a representative 1.22% effective rate as a planning estimate.

What counts as an exemption here?

Enter any reduction to your assessed value, such as a senior or disability credit your assessor applies. The tool subtracts it from the assessed value before computing tax.

Is my property data private?

Yes. The estimate is computed entirely in your browser, and nothing you enter is uploaded, logged, or stored.

Buying or budgeting for a home in the City of St. Louis means planning for property tax, which runs at an effective rate of about 1.22% of market value. This estimator converts your home’s value into Missouri’s assessed value, applies the local levy, and shows both the annual bill and a monthly escrow equivalent so the cost is easy to budget.

How it works

Missouri does not tax the full value of your home. The calculation has three steps:

Assess. Multiply market value by the residential assessment ratio of 19% to get the assessed value.
Subtract any exemption or credit from the assessed value to get the taxable base.
Apply the levy. The City of St. Louis combined levy works out to about 6.42% of assessed value, which is equivalent to 1.22% of market value.

So for a $250,000 home: assessed value is $47,500, and at the effective rate the annual tax is roughly $3,050, or about $254 per month in escrow.

Tips and notes

Use your purchase price or a recent appraisal as the market value for the closest estimate. Real bills shift year to year as the city sets levies and voters approve bond measures, and some parcels sit inside special districts that add a small surcharge. Treat this estimate as a planning baseline and confirm the exact figure with the St. Louis Collector of Revenue once you have an assessment notice.
