How to Use Indiana Income Tax Calculator Online
Indiana individual income tax is administered by the Indiana Department of Revenue (DOR) and is characterized by a low state flat tax rate (3.05% in 2024, 3.00% in 2025, stepping down toward 2.90%) combined with mandatory County Local Income Taxes (LIT) across all 92 Indiana counties. Unlike many states with progressive brackets, Indiana's two-layer flat structure creates a predictable tax environment with targeted personal exemptions ($1,000 basic / $1,500 dependent child), generous renter's deductions ($3,000), and homeowner property tax deductions ($2,500).
