What is Marion County's local income tax rate?
Marion County (Indianapolis) levies a 2.02% local income tax (LIT) on Indiana state taxable income, on top of Indiana's flat state income tax rate -- collected together on the same state return, not as a separate city filing.
Do Indiana non-residents pay a lower local tax rate than residents?
No -- and this is a real distinction from Pennsylvania and Michigan's commuter cities, not the same rule with a different number. Indiana repealed its split resident/non-resident LIT rates in 2015; every filer pays the full county rate for the county where they work or live, whichever applies under Indiana's county-selection rule below.
Which Indiana county's rate applies to me?
Indiana's Department of Revenue applies the rate for the county where you lived on January 1 of the tax year -- and only if you had no Indiana county residence on that date does your county of principal employment on January 1 apply instead.
