Indiana's top marginal state income tax rate is 3.05%. 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.
Constitutional property tax caps limit bills to a share of assessed value. Statewide median household income is $70,000, which is the default loaded above.
Remember that a state with no income tax is not automatically cheaper overall. Indiana has an effective property tax rate of 0.75% and average homeowners insurance of $1,400 a year — states without wage income tax typically recover revenue through property or sales taxes.
