Enter your annual gross income, select your filing status, and choose your county of residence. Indiana levies both a flat state income tax and a separate county income tax. Results update instantly as you type.
Indiana's standard deduction ($1,000 single / $2,000 MFJ) is applied before calculating both state and county tax. The county tax rate is based on where you live on January 1, not where you work.
