Missouri Property Tax Calculator - Market value to annual bill
This Missouri Property Tax Calculator estimates the annual bill on a home by applying Missouri's 19% residential assessment ratio to market value, then your local rate in cents per $100 of assessed value, and any circuit-breaker credit.

What Is Missouri Property Tax Calculator?
The Missouri Property Tax Calculator turns a home's market value into the annual property tax you actually owe under Missouri's assessment system. Missouri does not tax a property at its full price. Instead, your county assessor first reduces true market value to an assessed value using a class-specific ratio, and most owner-occupied homes are assessed at 19% of true value. The calculator applies that reduction, multiplies by your local levy, and subtracts any state property tax credit so you see the real bill rather than a raw rate guess.
- • Before you buy: Model the annual and monthly levy on a listed home so the tax is part of the offer, not a surprise after closing.
- • After a reassessment notice: Check whether the assessor's true value or ratio moved the bill, and whether an appeal is worth filing.
- • Comparing counties: Hold the home price fixed and change only the local cents-per-$100 rate to see how location alone moves the bill.
- • Modeling the credit: See the net bill after the circuit-breaker credit for a senior, disabled, or disabled-veteran household.
Missouri's system has two distinct steps that confuse people who compare it to a flat percentage of sale price. The first step lowers the value (the assessment ratio), and the second step applies a locally set levy quoted in an unfamiliar unit (cents per $100 of assessed value). This calculator strings those two steps together and shows the assessed value and effective rate separately.
Use the Missouri Property Tax Calculator before you buy, when you receive a reassessment notice, or when you compare neighborhoods across Missouri counties. The effective rate on market value is the figure that lets you compare a low-priced county with a high-priced one fairly, because it folds both the ratio and the levy into one percentage of the home's price.
If you are also weighing take-home income, the Missouri Paycheck Calculator shows the income side of your household budget while this tool shows the real-estate side.
How Missouri Property Tax Calculator Works
The calculator follows the same sequence Missouri counties use to build the bill, so the result matches the order a tax office applies.
- Market value: The true value in money of the real property before any assessment reduction, usually from a sale, appraisal, or the assessor's record.
- Assessment ratio: The class percentage that reduces market value to assessed value: residential real 19%, agricultural 12%, commercial/industrial/utility 32%, personal property 33.33%.
- Tax rate (cents per $100): The combined local levy in cents per $100 of assessed valuation from your tax bill or county collector.
- Property tax credit: The Missouri circuit-breaker credit for qualifying seniors, disabled individuals, or 100% disabled veterans, entered as a dollar amount.
First, assessed value equals market value times the assessment ratio. A $250,000 home at the 19% residential ratio produces a $47,500 assessed value. Second, the local tax rate is applied. Missouri rates are quoted in cents per $100 of assessed valuation, so a rate of 650 cents per $100 is the same as 6.5% of assessed value. The annual tax is $47,500 times 6.5%, or $3,087.50. Third, any circuit-breaker credit is subtracted to reach the net tax, which divided by twelve gives the monthly figure.
Typical Kansas City home
Market value is $250,000 at the 19% residential ratio, with a combined rate of 650 cents per $100 and no credit.
Assessed value is $250,000 x 0.19 = $47,500. Annual tax is $47,500 x (650 / 100) = $47,500 x 6.5% = $3,087.50.
The annual bill is $3,087.50, or about $257 a month before any credit.
A 650 cents-per-$100 rate is 6.5% of assessed value, and the effective rate on the $250,000 market value is about 1.24%.
According to Missouri Department of Revenue, property is assessed at a percentage of true value and taxed by locally set levies in cents per $100 of assessed valuation
The same reduced-value method appears in other states, and the Alabama Property Tax Calculator walks through a 10% ratio so you can see how Missouri's 19% home ratio differs.
Key Concepts Explained
Four ideas decide almost every Missouri property tax result, and the first one is the reason a home's price and its tax bill are rarely proportional.
Assessed value
The reduced figure your tax is actually charged on, not the price you paid. It equals market value times the class assessment ratio.
Assessment ratio
The class percentage set by Missouri law: residential real 19%, agricultural 12%, commercial, industrial, and utility 32%, and personal property 33.33%.
Cents per $100 of assessed value
The local levy unit. Divide the cents figure by 100 to get the decimal rate on assessed value; 650 cents per $100 equals 6.5%.
Circuit-breaker credit
A state credit for qualifying seniors, disabled residents, and 100% disabled veterans that lowers the net bill after the levy is applied.
These classes matter because two neighbors with identical market values can owe very different bills if one owns a farm (12% ratio) and the other a shop (32% ratio). The Missouri Property Tax Calculator shows the assessed value separately so you can see which piece moved the bill.
The rental property tax treatment uses the same ratios but applies them to income-producing real estate, which the Rental Property Tax Calculator separates from owner-occupied homes.
How to Use This Calculator
Follow these steps to get a dependable estimate you can act on.
- 1 Find market value: Use a recent appraisal, sale price, or the county assessor's recorded true value for the property.
- 2 Pick the assessment ratio: Choose the ratio that matches your property class; most owner-occupied homes use 0.19.
- 3 Locate the combined rate: Read the rate in cents per $100 from your latest tax statement or the county collector's website.
- 4 Enter any circuit-breaker credit: Add the credit you expect to claim if you qualify as a senior, disabled, or disabled veteran.
- 5 Read the outputs: Note the assessed value, annual tax, net tax after credit, and monthly tax.
- 6 Compare the effective rate: Use the effective rate on market value to compare districts before you commit to a purchase.
A $320,000 St. Louis County home at the 19% ratio with a 720 cents-per-$100 rate and a $1,100 credit owes $3277.60 a year, or about $273 a month. Because property tax sits alongside a mortgage payment, the Home Affordability Calculator helps you see whether that monthly tax fits the purchase you are planning.

Benefits of Using This Calculator
The calculator replaces guesswork with numbers you can act on.
- • Separate assessed value: Shows the reduced base on its own so you can spot whether a reassessment pushed your ratio or true value up.
- • Fair county comparison: Computes the effective rate on market value, the figure that lets you compare a low-priced county with a high-priced one fairly.
- • Models the credit: Renders the circuit-breaker credit so senior and disabled owners see their real net bill rather than the gross levy.
- • Scales to other classes: Lets you change the ratio to price personal or agricultural property, not only owner-occupied homes.
It pairs naturally with income planning if you want the full monthly cost of owning in Missouri. Seeing the net bill after credit is the difference between budgeting the gross levy and budgeting what you will actually pay.
A border shopper can compare the net cost of owning in Missouri against Kansas, where the Kansas Paycheck Calculator and local rates follow a different model.
Factors That Affect Your Results
Five things move the number most, and the local levy dominates once the property class is fixed.
Assessment ratio
The largest lever after value; switching from the 19% residential ratio to the 12% agricultural ratio cuts assessed value by more than a third.
Local levy rate
Set by school, county, city, and fire districts and varies widely; a border shopper sees different totals than in Kansas, where the Kansas Paycheck Calculator and local rates follow a different model.
Property tax credit
Can zero out the bill for qualifying seniors, disabled residents, and disabled veterans.
Reassessment timing
Missouri reassesses real property in odd-numbered years, so the true value on your bill can lag a moving market by a year or more.
- • The calculator uses one combined cents-per-$100 rate and does not separate the school, county, city, and fire district levies shown on a real tax statement.
- • It estimates the bill from the inputs you enter and does not pull live assessed values, current levies, or your exact credit amount from county records.
- • Some special districts and voter-approved bonds add charges that may appear on the actual bill but are not part of the combined rate entered here.
County comparison is the practical takeaway: two $300,000 homes can owe thousands apart depending on the levy. The Missouri Property Tax Calculator makes that gap visible before you move, not after the first tax bill arrives.
Because the local levy drives most of the bill, comparing district rates before buying is often the largest lever you have. The assessment ratio and reassessment schedule are largely fixed by state law and property class.
According to Missouri Department of Revenue, the property tax credit (circuit breaker) returns tax to qualifying seniors, disabled individuals, and 100% disabled veterans based on income and amount paid
The Arizona Property Tax Calculator shows a similar ratio-based system in another state, which makes the Missouri ratios easier to judge by contrast.
Frequently Asked Questions
Q: How is Missouri property tax calculated?
A: Missouri multiplies your property's true market value by a class assessment ratio to get the assessed value, then multiplies that assessed value by the local rate expressed in cents per $100 of assessed value. Any qualifying circuit-breaker credit is subtracted last. A $250,000 home at the 19% residential ratio with a 650 cents-per-$100 rate owes about $3,087.50 a year before credits.
Q: What is the Missouri residential assessment ratio?
A: Residential real property in Missouri is assessed at 19% of true value. Agricultural land is assessed at 12%, commercial, industrial, and utility property at 32%, and personal property at 33.33%. The ratio, not the tax rate, is what reduces market value to the figure your levy is charged on.
Q: How do Missouri tax rates in cents per $100 of assessed value work?
A: Missouri levies are quoted in cents per $100 of assessed valuation. To convert, divide the cents figure by 100 to get a decimal rate on assessed value. For example, 650 cents per $100 equals 6.5% of assessed value. You can read the combined rate on your annual tax statement or your county collector's website.
Q: What is the Missouri property tax credit (circuit breaker)?
A: The circuit breaker is a state credit for certain seniors, disabled individuals, and 100% disabled veterans on real estate or personal property they own and occupy. It lowers the net bill after the local levy is applied. The Missouri Department of Revenue publishes the income limits and credit amounts each year, and the credit can reduce the amount you owe to zero for qualifying owners.
Q: How does Missouri property tax compare by county?
A: The assessment ratio is the same statewide by property class, so differences between counties come almost entirely from the local levy rate set by school, county, city, and fire districts. Two homes with the same market value can owe very different bills depending on the combined cents-per-$100 rate in each district.
Q: How can I lower my Missouri property tax bill?
A: You can appeal the assessed true value if it is higher than recent sales, make sure you are on the correct assessment ratio for your property class, and claim the circuit-breaker credit if you qualify as a senior, disabled, or disabled veteran. Because the local levy drives most of the bill, comparing district rates before buying is often the largest lever.
