How to use it
A two-minute guide.
The Home Value field is pre-filled with St. Louis's median home value of $180,000. Override with your actual home's market value for a specific estimate — your tax bill scales linearly with home value.
The rate is pre-filled with St. Louis City's effective rate of 1.02% — the county-level average for owner-occupied homes, which is more precise than Missouri's statewide average of 1.01%. Individual school districts and special taxing zones within St. Louis still shift the exact figure — if you know the rate from your latest tax bill, override it for the most precise estimate.
You'll see your estimated annual property tax, the monthly amount (which is typically escrowed with your mortgage payment), and a comparison to other states.
How it works
The math behind the result.
How St. Louis's tax bill works out. Homes in St. Louis are assessed and billed through St. Louis City. The effective rate there averages about 1.02% of market value — right around Missouri's statewide average. On St. Louis's median home value of $180,000, that's approximately $1,836/year, or $153/month when escrowed with your mortgage.
How assessment works in Missouri. Counties reassess in odd-numbered years; residential property is assessed at 19% of market value. The Hancock Amendment forces rate rollbacks when reassessment growth exceeds inflation.
Exemptions worth claiming. Missouri's main relief is the Property Tax Credit (circuit breaker) for income-qualified seniors and disabled homeowners; recent law also lets counties freeze seniors' bills. Exemptions are the most common reason two identical St. Louis homes pay different tax bills — make sure yours are on file with St. Louis City.
What property tax actually pays for. In St. Louis — like the rest of Missouri — property tax funds local schools, public safety (police, fire), road maintenance, parks, libraries, and county government. Most of your bill stays in your county and school district.
Comparing to other states. Effective rates vary enormously across the US — from about 0.3% in Hawaii to nearly 2.5% in New Jersey. St. Louis's 1.02% puts it near the middle nationally.
