Easy Indiana State Taxes with 3% Flat Rate in 2024-2025

Indiana features a straightforward flat individual income tax rate of 3% on adjusted gross income (for tax year 2025, effective for returns filed in 2026). This is a reduction from 3.05% in 2024, thanks to ongoing phased cuts under state law (H.B. 1001 from 2023 and updates). The rate is scheduled to drop further to 2.95% in 2026 and 2.9% in 2027 and beyond. Note: Many counties add a local income tax (typically 0.5%–2.9%, varying by county), so your combined rate may be higher—TurboTax calculates this automatically based on your address.

Whether you're a full-year resident, part-year resident, or nonresident with Indiana-sourced income, TurboTax makes handling Indiana state taxes effortless alongside your federal return.
