Local income tax, state by state.

Most Americans pay federal and state tax. Some also pay their city, their county or their school district. We hold 4,129 of those local taxes across 10 states. A state missing from this list levies none that we model.

Local income taxation is the least-published layer of the US tax stack and the one most often omitted from take-home calculators entirely. This dataset holds 4,129 jurisdictions across 10 states, each with its own rate and citation. Every state below declares whether that coverage is complete or partial, so an absent address can be distinguished from an unmodelled one — a distinction that otherwise renders as an identical silent zero.
