Indiana Income Tax Brackets & Rates 2026

Indiana Income Tax Overview for 2026

Indiana (IN) imposes a flat income tax rate of 3.05% on all taxable income. Indiana has a flat 3.05% state rate. Counties may impose additional local income taxes ranging from 0.5% to 2.9%.

For the 2026 tax year, Indiana residents must file both state and federal income tax returns. Your IN state tax is calculated on your state taxable income, which generally starts with your federal adjusted gross income (AGI) and applies state-specific adjustments and deductions. Indiana uses a personal exemption system rather than a standard deduction.

Your combined federal and IN effective tax rate depends on your total income, filing status, deductions, and credits.

SALT Deduction and Indiana Taxes in 2026

The State and Local Tax (SALT) deduction allows taxpayers who itemize on their federal return to deduct state and local taxes paid, including state income taxes and property taxes. Under the One Big Beautiful Bill Act (OBBBA), the SALT cap has been raised to $40,000 for the 2026 tax year, up from the $10,000 cap that was in place since 2018.

For Indiana residents, this is significant. With IN's moderate tax rates, most residents will find the $40,000 SALT cap more than sufficient to deduct all their state and local taxes. Taxpayers should compare their total SALT amount against the $40,000 cap to determine whether itemizing benefits them over the standard deduction.

The $40,000 SALT cap applies to the combined total of state income taxes (or sales taxes if elected), local income taxes, and property taxes. This cap is the same regardless of filing status. Use our SALT Deduction Calculator to determine your optimal strategy.

How Federal Taxes Apply to Indiana Residents

All Indiana residents are subject to federal income tax, which uses seven progressive brackets for 2026: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. The federal standard deduction is $16,100 for single filers and $32,200 for married filing jointly. Under the OBBBA, new provisions include tax-free overtime pay, tax-free tips for service workers, and an additional $4,000 deduction for seniors aged 65 and older.

Your total tax liability as a IN resident combines your federal tax obligation with your Indiana state tax plus FICA taxes (Social Security at 6.2% and Medicare at 1.45%). Self-employed individuals in Indiana owe both the employee and employer portions of FICA (15.3% total) but can deduct the employer portion. Use our Federal Income Tax Calculator to compute your exact federal liability.

Tax Planning Tips for Indiana Residents

• Evaluate itemizing vs. standard deduction: With the $40,000 SALT cap, IN residents with high state income and property taxes should compare their itemized deductions against the standard deduction each year.
• Maximize retirement contributions: Contributing to a 401(k) or traditional IRA reduces both your federal and Indiana taxable income, providing a double tax benefit.
• Consider HSA contributions: If eligible, an HSA provides triple tax savings: deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. The 2026 limit is $4,300 for individuals.
• Review withholding: Use your combined federal and state tax liability to ensure proper withholding, avoiding both underpayment penalties and excessive refunds.
• Track estimated payments: If you have self-employment income or significant investment income, make quarterly estimated payments to both the IRS and Indiana to avoid penalties.

Indiana vs. Other States: Tax Comparison

Compared to the national landscape, Indiana's top rate of 3.05% is well below the national average. This positions Indiana as a relatively tax-friendly state compared to high-tax states like California and New York. When comparing states, consider the full tax picture including property taxes, sales taxes, and cost of living, not just income tax rates.

Indiana Tax Overview

Indiana has a flat 3.05% state income tax rate, one of the lowest flat rates in the nation. However, all 92 Indiana counties impose additional local income taxes ranging from 0.5% to 2.9%, which are withheld by employers alongside state tax. The combined state and county rate can reach nearly 6% in some counties. Indiana property taxes are capped at 1% of assessed value for homesteads, 2% for rental property, and 3% for commercial property.

Indiana has a state sales tax rate of 7.00% and an average effective property tax rate of 0.81%. When combined with the income tax, these additional levies form the complete state tax picture that residents should evaluate. The Indiana tax authority (Indiana Department of Revenue) oversees all state tax administration and can be reached at (317) 232-2240 for questions about filing, payments, and account issues.

Understanding how Indiana's tax system interacts with federal taxes is critical for accurate financial planning. Your combined effective tax rate includes federal income tax (10% to 37%), Indiana state income tax, FICA taxes (7.65% for employees), and any applicable local taxes. Proper planning across all these layers can save thousands of dollars annually.

Indiana Tax Deductions and Credits

Indiana uses personal exemptions ($1,000 per person plus $1,500 additional for dependents) rather than a standard deduction. The state offers a renter's deduction (up to $3,000 of rent paid), a mortgage interest deduction, an elderly credit ($100 per eligible person over 65), a unified tax credit for the elderly ($140 per person with income under $10,000), a credit for taxes paid to other states, and a college contribution credit (20% of contributions to Indiana 529 plans, up to $1,500 per year). Military pay is exempt from Indiana tax.

In addition to state-specific benefits, Indiana residents can take advantage of federal tax deductions and credits. For the 2026 tax year, key federal provisions include the standard deduction ($16,100 single, $32,200 married filing jointly), the child tax credit (up to $2,000 per qualifying child), the earned income tax credit for low-to-moderate income workers, and the $40,000 SALT deduction cap under the OBBBA. Indiana state income taxes are included in the SALT calculation, so residents paying significant state income tax should evaluate whether itemizing produces a larger deduction than the standard deduction.

Taxpayers should also explore retirement-related tax benefits available to Indiana residents. Contributions to 401(k) plans (up to $23,500 for 2026, plus $7,500 catch-up for age 50+) and traditional IRAs (up to $7,000, plus $1,000 catch-up) reduce both federal and state taxable income. Health Savings Account (HSA) contributions provide a triple tax benefit: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses.

Tax Tips for Indiana Residents

Indiana residents should note that county tax rates vary significantly, so check your specific county rate. File electronically through INfreefile.com for the fastest refunds. The Indiana 529 college savings plan credit (20% of contributions, up to $1,500 annually) is one of the most generous in the nation. Renters can deduct up to $3,000 of rent paid to reduce their taxable income. If you moved between Indiana counties during the year, prorate your county tax. Indiana offers an automatic 60-day extension to file if you request a federal extension.

For the 2026 tax year, Indiana residents should also be aware of key provisions under the OBBBA. Overtime pay (beyond 40 hours per week) is exempt from federal income tax, tips earned by service workers are federally tax-free, and seniors age 65+ receive an additional $4,000 federal deduction. These provisions apply to IN residents regardless of state tax status and can significantly impact take-home pay and total tax liability.
