Indiana has a 2.95% flat state income tax for 2026 — one of the lowest state rates in the Midwest, and cut for the fifth consecutive year. However, most residents also pay local county taxes.
Indiana State Income Tax Rate
| Tax Type | Rate |
|---|---|
| State income tax | 2.95% (flat, 2026) |
| County income tax | Roughly 0.5% - 3.13% (confirm current rates by county) |
| Total combined rate | Roughly 3.45% - 6.08% |
Indiana uses a flat tax rate — everyone pays the same state percentage regardless of income. The state rate has been cut every year since 2022: 3.23% (2022) → 3.15% (2023) → 3.05% (2024) → 3.00% (2025) → 2.95% (2026), under a framework (HEA 1001) that ties each 0.05-point cut to revenue growth and budget reserve targets being met.
