Indiana Tax Estimator

You can use the income tax estimator to the left to calculate your approximate Indiana and Federal income tax based on the most recent tax brackets.

Keep in mind that this estimator assumes all income is from wages, assumes the standard deduction, and does not account for tax credits.

For a more detailed estimate that takes these factors into account, click "View Detailed Estimate" (this will will redirect to an external website).

Deductions

When calculating your Indiana income tax, keep in mind that the Indiana state income tax brackets are only applied to your adjusted gross income (AGI) after you have made any qualifying deductions.

Qualifying deductions might include an itemized deduction, the Indiana standard deduction, exemptions for dependants, business expenses, etc.

Remember that Indiana may have very different deduction laws from the Federal Income Tax, so you may have to write a whole new list of deductions for your Indiana income tax return.
