Virginia's top marginal state income tax rate is 5.75%. 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.
Property tax varies widely between Northern Virginia and the rest of the state. Statewide median household income is $90,000, which is the default loaded above.
Remember that a state with no income tax is not automatically cheaper overall. Virginia has an effective property tax rate of 0.8% and average homeowners insurance of $1,300 a year — states without wage income tax typically recover revenue through property or sales taxes.
