Indiana Tax Overview
Indiana uses a flat 3.05% income tax rate applied to all taxable income, regardless of earnings level. The simplicity means a $50,000 earner and a $200,000 earner pay the exact same marginal rate — a design that favors higher earners compared to graduated bracket systems. County income taxes add 0.5%–2.9% depending on county.
