Indiana State Tax Deductions 2026

Indiana State Tax Deductions 2026 – Indiana offers a flat individual income tax rate of 2.95% for tax year 2026 (down from 3% in 2025), plus county income taxes that vary by location. Unlike the federal system, Indiana does not provide a standard deduction. Instead, you start with your federal adjusted gross income (AGI) from Form 1040 and subtract specific Indiana deductions on Schedule 2 (for full-year residents using Form IT-40) or Schedule C (for part-year/nonresidents using IT-40PNR). You then apply exemptions on Schedule 3 before calculating your state and county tax liability.

These deductions can significantly lower your taxable income, especially for retirees, military families, homeowners, renters, and workers with new qualifying income like tips or overtime. Always use the latest official forms and instructions from the Indiana Department of Revenue (DOR) at in.gov/dor, as rules can be updated by the General Assembly.

Major Changes to Indiana Tax Deductions for 2026

Lawmakers passed targeted conformity with certain federal provisions from the One Big Beautiful Bill Act (OBBBA) for tax year 2026 only. Key updates include:

Tips and overtime pay deduction: Indiana allows a deduction for qualifying tips and overtime wages earned in 2026 (filed in 2027). This aligns with federal rules but applies specifically to state and county income tax. Details on limits and eligibility will appear in 2026 forms and bulletins.
Qualified vehicle loan interest deduction: You may deduct interest paid on loans for new, U.S.-assembled passenger vehicles (up to federal limits, such as $10,000 per return, with phase-outs based on modified AGI). This is temporary and tied to 2026 income.

Property tax relief also evolves in 2026. The homestead supplemental deduction increases (phasing toward 66.7% of assessed value by 2031), and new credits apply to homestead property tax bills. These reduce your actual property tax owed but are separate from income tax deductions.

How Indiana Tax Deductions Work?

Report federal AGI on your Indiana return.
Add back certain items on Schedule 1 (if required).
Subtract qualifying Indiana deductions on Schedule 2 or Schedule C.
Claim exemptions (e.g., $1,000 per federal exemption, plus extras for dependents, age 65+, or blindness) on Schedule 3 and IN-DEP.
Calculate county tax on Schedule CT-40.

Most deductions require supporting documentation (e.g., Form 1099-G for unemployment, employer statements for enterprise zones, or loan statements for vehicle interest). File electronically via INTIME or freefile.dor.in.gov for faster processing and error checks. The 2026 filing deadline for 2025 taxes is April 15, 2026, but 2026 tax-year rules apply to income earned January 1–December 31, 2026.
