Kansas's top marginal state income tax rate is 5.58%. 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.
High hail and wind exposure drives insurance premiums up. Statewide median household income is $71,000, which is the default loaded above.
Remember that a state with no income tax is not automatically cheaper overall. Kansas has an effective property tax rate of 1.26% and average homeowners insurance of $2,900 a year — states without wage income tax typically recover revenue through property or sales taxes.
