Indiana County Selection for Individual Income Tax
When filing your Indiana individual income tax return, selecting the correct county is essential for accurate tax calculation and compliance. The county selection impacts your county income tax rate, which is applied to your Indiana taxable income. This guide outlines key considerations for determining the appropriate county for your tax filing.
Key Considerations for County Selection
- Work Location: For wage earners, the county where you worked on January 1, 2025, determines your county tax rate. This is specified on Form IT-40RNR, Line 4A and 4B.
- Business or Self-Employment: If you operate a business or are self-employed in Indiana, the county where your business activities occur typically determines your county tax liability.
- Residence vs. Work Location: If you live in one county but work in another, you are generally taxed based on your work location, not your residence.
- Nonresident Filers: Nonresidents who earn income from Indiana sources must determine the county where the income was earned. This is especially important for those filing Form IT-40PNR.
Forms and Instructions for County Selection
Several Indiana tax forms provide guidance on county selection and tax calculation:
- Form IT-40RNR: Used by nonresidents with wage income. Line 4A and 4B require entering the county tax rate based on the county of employment on January 1, 2025.
- Form IT-40PNR: For nonresidents with income from sources other than wages (e.g., business income, investments). County tax is determined based on the location of the income source.
- Schedule IT-2210A: Provides a worksheet for annualizing income and calculating state and county taxes, including county tax rates.
- Schedule IT-2210: Includes instructions for calculating total Indiana tax, including county tax, based on the appropriate forms.
Important Notes
- County tax rates vary by county and are applied to your Indiana taxable income after exemptions and deductions.
- For nonresidents, income from Indiana sources such as business operations, real estate, or services rendered in Indiana must be reported with the correct county designation.
- Reciprocal state residents (e.g., from Kentucky, Ohio, Pennsylvania, Michigan, or Wisconsin) may have special rules for county tax determination — refer to Form IT-40PNR, page 62.
