Indiana Tax Tables
Indiana Tax Tables provide a complete reference of how state income tax is calculated for each supported year. These tables summarise the official rules issued by the Indiana Department of Revenue and present them in a clear structure that matches the calculations used in our Indiana Tax Calculator. They are useful for checking withholdings, estimating liability, reviewing historical tax years and understanding how state policy shapes taxable income.
Quick Access Tools
Tax Years
Select a tax year to view the official Indiana tax rates and rules used in our calculators. Each page shows the brackets or flat tax rate, deduction amounts, credit structures, withholding guidance and any year-specific updates published by the Indiana Department of Revenue. You can also access the matching Indiana Tax Calculator for precise calculations for that year.
How Indiana Calculates Income Tax
Indiana uses a flat income tax rate applied to all taxable income. These rules determine how wages and other taxable income are assessed for Indiana returns, with updated tables released each year to reflect legislation and inflation changes. For a broader explanation of how tax tables work, see our Tax Tables guide.
Certain jurisdictions within Indiana also levy local or county income taxes. These appear in the annual state tax tables and may affect residents, part-year residents or nonresidents depending on local rules.
Indiana supports resident, nonresident and part-year filing rules. The tax tables help clarify which thresholds apply when income is earned both inside and outside the state.
What Is Contained in the Indiana Tax Tables?
Each tax-year page provides a structured summary of the components Indiana uses to calculate individual income tax. While details vary by year, the state tax tables generally include the following elements:
- Flat tax rate applied to taxable income.
- Standard deduction amounts for each filing status.
- Itemized deductions where permitted under Indiana law.
- Dependent and family-related credits including any child-based or filer-based reductions.
- State Earned Income Credit (EIC), including percentage match and income limits.
- Retirement income rules including partial or full exemptions for pensions or Social Security.
- State withholding tables used by employers for payroll calculations.
Together, these elements provide a transparent breakdown of how Indiana calculates tax for each year. This structure helps taxpayers review year-to-year changes, employers validate payroll withholding and financial planners analyse how Indiana’s rules differ from federal requirements. All values shown in our Indiana Tax Tables match the official figures published by the state.
