Indiana 2025 State Instructions
For individuals filing Indiana state income tax for the 2025 tax year, the Indiana Department of Revenue (DOR) provides detailed instructions and forms to ensure accurate and compliant returns. Below are key points and guidance based on the official 2025 Indiana state tax forms and instructions.
Key Forms and Instructions
- Form IT-40: This is the primary form for Indiana residents and part-year residents. It requires completion of your federal Form 1040/1040-SR first, as many line references are based on federal return data.
- Form IT-40PNR: Used by full-year nonresidents who have income from Indiana sources. This form includes specific instructions for reporting income derived from Indiana, such as business income, rental income, or professional services.
- Form IT-40RNR: Designed for reciprocal nonresidents. Due by April 15, 2026, for the 2025 tax year.
- Schedule IT-2210: Used to calculate total tax liability, including state and county income tax, recapture of credits, and pass-through entity tax (PTET).
- Schedule IT-2210A: For annualizing income when filing for partial-year residency or when income is received in uneven periods.
Important Tax Rules and Considerations
- Federal Credit Limitation: Indiana does not adopt the federal refundable credit under IRC section 23a)(4). Therefore, any federal credit exceeding your federal tax liability (after applying required credits) is not allowed for Indiana tax purposes.
- Income from Indiana Sources: Nonresidents must report income derived from Indiana sources, including business income, rental income, and professional services. However, interest, dividends, unemployment compensation, and gains from securities are generally taxed by the state of residence.
- Conformity with Federal Law: Indiana conforms to the Internal Revenue Code as of January 1, 2023. If changes occur in federal law after that date, taxpayers may need to amend their returns if Indiana does not adopt those changes.
- Estimated Tax Payments: Use Form ES-40 to make estimated tax payments for the 2026 tax year (for 2025 income).
How to File Electronically
