Missouri Property Tax Calculator

The effective property tax rate in Missouri is 0.97% of assessed home value, based on Tax Foundation 2024 published state averages. On a $300,000 home that works out to roughly $2,910 per year, or about $242 per month. Your actual bill depends on your county, your local millage rate, and any exemptions you qualify for.

The basic formula this calculator uses is: annual property tax = home value × effective tax rate. For example, a $500,000 home at Missouri's 0.97% effective rate is $4,850 per year. Missouri counties typically assess your home, multiply the assessed value by a local millage rate, then subtract any homestead, senior, veteran, or disability exemptions you have filed for. Effective rate already accounts for assessment ratios statewide, so it is the cleanest way to compare states.

Most Missouri counties bill property taxes either annually or semi-annually, with due dates varying by county. If your mortgage has an escrow account, your servicer typically collects 1/12 of your annual property tax with each monthly payment and pays the county directly when the bill comes due. Check your county assessor or treasurer's website for the exact billing schedule in your jurisdiction.

Most states, Missouri included, offer at least one of the following exemptions that can lower your taxable assessed value: a homestead exemption for your primary residence, a senior citizen exemption (often age 65+), a disability exemption, and a veteran/disabled-veteran exemption. Eligibility, application deadlines, and exemption amounts vary by county. This calculator does not factor exemptions in — it shows a pre-exemption estimate so you can see your gross liability before reductions.

This calculator uses the Missouri statewide average effective rate (0.97%). Your actual bill can differ for several reasons: your county or municipality's millage rate is higher or lower than the state average, your assessed value differs from your market value (assessment ratios vary), special assessment districts (school, fire, library) add line items, and exemptions reduce your taxable base.
