Missouri property taxes sit comfortably close to the national average, with a statewide effective rate of 0.89%. The state employs a unique fractional assessment system, meaning your home is only taxed on 19% of its true market value. Thanks to the Hancock Amendment, local governments are forced to roll back tax rates during revaluation years to prevent “stealth” tax hikes, and a recent 2024 expansion of SB 190 allows counties to freeze tax bills entirely for eligible seniors (est., Tax Foundation 2026 / U.S. Census ACS 2023).
With a statewide effective property tax rate of 0.89%, Missouri homeowners pay slightly less than the national average (0.90%). Because Missouri’s median home values are relatively affordable (around $215,000), the actual dollar amount paid by homeowners is quite low compared to coastal states. The property tax system is characterized by a fractional assessment structure (taxing only 19% of a home’s value) and strict biennial reassessment cycles that occur exclusively in odd-numbered years.
The 19% Assessment Ratio and Odd-Year Reappraisals
Property in Missouri is classified and assessed differently based on its use, as mandated by the Missouri State Tax Commission. Commercial property is assessed at 32% of its market value, and agricultural land at 12%. However, residential real property is assessed at 19% of its true market value.
For example, if the County Assessor determines your home has a true market value of $200,000, your Assessed Value for tax calculation purposes is only $38,000.
Missouri operates on a strict biennial (two-year) reappraisal cycle. Reassessments happen solely in odd-numbered years (e.g., 2023, 2025, 2027). The assessed value established in an odd year carries over and remains flat during the subsequent even-numbered year, provided the homeowner makes no major improvements (like building an addition or a detached garage) to the property.
Missouri statewide effective rate. On a $215,000 home, expect approximately $1,913 per year at the statewide average. Actual bills depend heavily on county and school district levies (est., Tax Foundation 2026 / Census ACS 2023).
| Home Value | Annual Tax (est.) | Monthly Payment | vs. U.S. Average |
|---|---|---|---|
| $150,000 | $1,335 | $111 | -$15 below avg. |
| $215,000 | $1,913 | $159 | -$22 below avg. |
| $350,000 | $3,115 | $259 | -$35 below avg. |
| $500,000 | $4,450 | $370 | -$50 below avg. |
| $750,000 | $6,675 | $556 | -$75 below avg. |

The Hancock Amendment: Preventing “Stealth” Tax Hikes
The Missouri Constitution includes a taxpayer protection clause known as the Hancock Amendment. It prevents local governments and school districts from reaping an automatic revenue windfall simply because property values increased during an odd-year reassessment.
Under the Hancock Amendment, if a countywide reassessment causes the total assessed value of existing property in a jurisdiction to increase faster than the rate of inflation, the local government must mathematically roll back its tax levy rate. This ensures their revenue only grows at the rate of inflation (plus revenue from new construction). While this forces the local tax rate down, it does not guarantee that an individual homeowner’s tax bill will decrease, especially if their specific home appreciated much faster than the county average.
Tax Relief: SB 190, the Circuit Breaker, and Veterans
Missouri offers several targeted tax relief programs, recently expanded during the 2023 and 2024 legislative sessions to assist seniors and veterans.
- The Senior Property Tax Freeze (SB 190 / SB 756): Enacted in 2023 and expanded in August 2024, this law allows counties to freeze the real property tax liability on the primary residence of seniors aged 62 or older. Crucially, this is a local-option law, not an automatic statewide freeze. It requires the county government to opt-in via ordinance or voter petition. If your county participates, you must manually apply with the County Collector/Assessor each year to lock in your owed tax amount.
- The Property Tax Credit (Circuit Breaker): Administered by the Missouri Department of Revenue, this program provides a state-level refund (up to $1,100 for homeowners and $750 for renters) to low-income seniors (65+, or 60+ surviving spouses) and 100% disabled individuals. Maximum income limits vary but generally hover between $30,000 and $34,000 depending on filing status.
- Disabled Veterans Exemption: Missouri offers a complete, 100% property tax exemption on the primary homestead for any former Prisoner of War (POW) who has a 100% service-connected disability. 100% disabled veterans who were not POWs do not qualify for the full exemption, but they can still claim the Circuit Breaker tax credit refund through the DOR.
Major County Tax Rates in Missouri
Property tax rates in Missouri vary significantly based on urban vs. rural settings. The St. Louis and Kansas City metropolitan areas (including St. Louis County, St. Charles County, and Jackson County) feature the highest effective tax rates in the state, generally hovering between 1.05% and 1.14%. This is driven by higher municipal service costs and robust school district levies.
In contrast, counties in the southwestern part of the state, such as Greene County (Springfield) and Jasper County (Joplin), boast some of the lowest effective property tax rates, remaining well under 0.70%.
| County / City | Effective Rate | Annual Tax on $215,000 Home | Notes |
|---|---|---|---|
| St. Louis County | 1.14% | $2,451 | Most populous county; high effective rate due to fragmented municipalities. |
| Jackson County | 1.11% | $2,386 | Includes Kansas City (Jackson County portion). |
| St. Charles County | 1.05% | $2,257 | Fast-growing suburban county west of St. Louis. |
| Greene County | 0.67% | $1,440 | Includes Springfield; very low effective tax rate. |
| St. Louis City | 1.02% | $2,193 | Independent city; operates separately from St. Louis County. |
| Clay County | 1.04% | $2,236 | Suburban Kansas City (Northland). |
| Jefferson County | 0.76% | $1,634 | Suburban county south of St. Louis; lower tax burden. |
| Boone County | 0.80% | $1,720 | Includes Columbia (University of Missouri). |
| Jasper County | 0.66% | $1,419 | Includes Joplin; lowest effective rate in the top 10. |
| Cass County | 0.85% | $1,827 | Suburban county south of Kansas City. |
Disclaimer and Methodology
This calculator provides estimates for planning purposes only, based on effective property tax rates (actual median taxes paid divided by median home values). Under Missouri law, residential property is assessed at just 19% of its true market value before local millage rates (expressed as dollars per $100 of assessed value) are applied. Because overlapping county, city, and school rates vary by exact location, this calculator bypasses the 19% fractional math to provide a historically accurate effective rate estimate that averages out jurisdictional differences.
What this calculator does not account for:
- The difference between your home’s current market value and its last appraised value. Missouri reassesses properties in odd-numbered years; your tax bill will not jump in an even-numbered year unless you made significant structural additions.
- Specific voter-approved school bonds or fire district levies applied on top of the base county rate.
- Personal property taxes on vehicles, boats, and RVs, which Missouri counties levy heavily and are completely separate from real estate taxes.
How to get an accurate estimate:
- Look up your property’s 19% Assessed Value on your County Assessor’s online parcel viewer.
- Multiply the Assessed Value by the total combined tax rate, then divide by 100.
- If you are 62+ and live in a county that passed SB 190, ensure you apply with your County Collector to freeze your tax bill amount.
