Pennsylvania's top marginal state income tax rate is 3.07%. 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.
Flat 3.07% state income tax, plus local earned income taxes. Statewide median household income is $76,000, which is the default loaded above.
Remember that a state with no income tax is not automatically cheaper overall. Pennsylvania has an effective property tax rate of 1.41% and average homeowners insurance of $1,200 a year — states without wage income tax typically recover revenue through property or sales taxes.
