Property taxes can feel like a moving target when you’re buying or selling in Webster Groves. You want a clear picture of what you’ll owe, how it’s calculated, and how it affects your monthly payment. With a little local context, you can plan confidently and avoid surprises at closing.
This guide walks you through how St. Louis County assesses and bills property taxes, what to watch in Webster Groves, and how escrow changes your monthly mortgage. You’ll also see an easy example you can adapt to your own home. Let’s dive in.
Who does what in St. Louis County
The property tax system involves a few different offices that each handle a piece of the puzzle:
- St. Louis County Assessor’s Office: estimates market value and sets your assessed value.
- St. Louis County Collector of Revenue: issues the bill, collects payments, and applies penalties for late or unpaid taxes.
- Local taxing authorities: the City of Webster Groves, Webster Groves School District, St. Louis County, and other districts set tax levies that combine into your total rate.
- State of Missouri: sets statewide assessment rules and certain exemptions or credits.
Why this matters to you: in Webster Groves, city and school district levies are typically significant parts of the bill. Your total rate depends on your exact parcel and which districts apply.
How your tax is calculated
At a high level, your annual property tax follows a simple flow.
Key terms to know
- Market value: what the Assessor estimates your home would sell for.
- Assessment rate: the percentage of market value used to calculate assessed value. Missouri sets this rate by statute for residential property. Verify the current percentage on state resources.
- Assessed value: market value multiplied by the assessment rate, adjusted for any exemptions or credits that apply.
- Total tax rate: the combined levies from the city, school district, county, and any special districts.
The basic formula
If the total tax rate is expressed as dollars per $100 of assessed value:
- Tax = (Assessed value ÷ 100) × Total tax rate
If the rate is shown as mills or a percentage:
- Tax = Assessed value × (Mill rate ÷ 1,000) or Tax = Assessed value × Tax rate as a decimal
A quick example
This is a hypothetical illustration to show the math. Always confirm the current assessment rate and your parcel’s combined tax rate before estimating.
- Example market value: $300,000
- Example residential assessment rate: 19 percent
- Assessed value: $300,000 × 0.19 = $57,000
- Example combined tax rate: $9.00 per $100 of assessed value
- Annual tax: ($57,000 ÷ 100) × $9.00 = 570 × $9.00 = $5,130
Your actual total rate will vary by parcel based on voter-approved levies and which districts apply. To get accurate numbers, review your property’s page in the St. Louis County Assessor’s parcel search and the County Collector’s tax bill lookup.
Assessments, notices, and appeals
The St. Louis County Assessor reviews properties and updates values using methods set by Missouri law. If your value changes, the Assessor provides a notice or posts the update in the public parcel database.
What you should do:
- Sellers: pull your latest assessed value and recent tax bills early. You will need them for prorations and to confirm whether anything is unpaid.
- Buyers: review the parcel’s assessed value and valuation history before you write an offer or remove contingencies. Ask your lender if taxes will be escrowed.
If you believe your assessed value is off, you can appeal. The appeal window is limited and starts after the valuation notice is issued. You’ll typically need support such as recent comparable sales, notes on condition, or corrections to property data. Check the Assessor’s website for current-year deadlines and instructions before the window closes.
Bills, due dates, and penalties
The St. Louis County Collector of Revenue sends property tax bills and manages payment processing. Due dates, accepted payment methods, and penalty schedules are set by the Collector and may change by year.
Practical tips:
- Confirm due dates and payment options with the Collector each year.
- Use the County’s taxpayer account or bill lookup to see if a parcel is paid or delinquent.
- If taxes are not paid by the due date, penalties and interest apply according to county and state rules. Long-term delinquency can lead to liens or tax sale processes.
At closing, title companies verify tax status. If there are delinquencies, they are typically paid from seller proceeds to clear title.
Escrow and your monthly mortgage payment
Most lenders include property taxes in your monthly payment using an escrow account. Here is how it works:
- Your lender estimates the coming year’s taxes and homeowners insurance.
- They divide the total by 12 and add that amount to your monthly mortgage payment.
- Under federal RESPA rules, lenders can keep a cushion in escrow, commonly up to two months of payments.
- Lenders perform an annual escrow analysis. If taxes rise, you may see a shortage and a higher monthly payment. If there is a surplus above a set threshold, you may receive a refund.
What it means for you:
- If you have an escrowed mortgage, your lender pays the St. Louis County Collector when taxes are due. You still receive analysis notices that show any changes to your escrow payment.
- If you pay cash or choose not to escrow, you will pay the Collector directly by the due date. Keep reminders on your calendar to avoid penalties.
Closing and tax prorations
Because St. Louis County bills annually, taxes are prorated between buyer and seller at closing based on the number of days each party owns the property during the tax year, or based on the period the bill covers. Your closing statement shows the proration and any tax-related credits or debits.
What sellers should do:
- Pull the most recent tax bill and verify if anything is unpaid.
- Resolve delinquencies through the closing process so you deliver clear title.
- Keep documentation handy for prorations.
What buyers should do:
- Ask your lender to confirm whether taxes will be escrowed and how they estimate the first year.
- Review the closing disclosure to understand the proration math.
- If the current-year bill is not out yet, expect the closing agent to estimate based on the last bill and current assessed value. A true-up may occur after the actual bill arrives.
Quick closing checklist:
- Verify parcel’s assessed value and bill history in county systems.
- Confirm escrow with your lender and ask about initial deposits and cushion.
- Review proration details with your closing agent.
- Make sure any delinquent taxes are paid from seller proceeds.
Webster Groves specifics to watch

Voter-approved changes can adjust rates from year to year. If you are estimating future taxes, review recent measures from the city and the school district to understand potential impacts.
Quick how-to: find your tax info
Here is a fast way to get parcel-specific numbers for a Webster Groves property:

Estimating your monthly payment
If you want a quick estimate that includes taxes, try this structure:
- Determine assessed value: Market value × assessment rate.
- Estimate annual tax: Assessed value × total tax rate for your parcel.
- Convert to monthly: Annual tax ÷ 12.
- Add PITI: Principal + Interest + Taxes + Insurance. This is your estimated monthly payment if escrowed.
Remember, the assessment rate is set by Missouri law, and total tax rates vary by parcel and year. Verify current figures in county and state resources before you finalize a budget.
