Missouri's top marginal state income tax rate is 4.7%. State tax is progressive here, so most filers pay an effective rate well below the top figure — the calculator applies a blended approximation rather than modeling the full bracket schedule.
Storm exposure across the state raises insurance costs. Statewide median household income is $68,000, which is the default loaded above.
Remember that a state with no income tax is not automatically cheaper overall. Missouri has an effective property tax rate of 0.88% and average homeowners insurance of $2,400 a year — states without wage income tax typically recover revenue through property or sales taxes.
