Indiana Paycheck Calculator (2025): Estimate Your Take-Home Pay
See exactly how much of your salary lands in your bank account after the 2025 state tax cut. We factor in federal taxes, FICA, the new 3.00% state rate, and specific county withholdings to give you a clear picture of your finances.
Understanding Your Indiana Paycheck in 2025
If you’ve looked at your pay stub recently, you might have noticed a small but welcome change. For 2025, Indiana has lowered its individual income tax rate to 3.00% (down from 3.05% in 2024). While 0.05% sounds small, it’s part of a planned series of cuts designed to keep more money in Hoosiers' pockets.
However, state tax is just one piece of the puzzle. Your take-home pay is also heavily influenced by where you live, thanks to Indiana’s unique system of county-level income taxes. Whether you’re in Marion County or Hamilton County, your local tax rate can swing your net pay by hundreds of dollars a year.
1Key 2025 Updates
- State Tax Cut: The flat income tax rate is now 3.00%.

How Are Your Taxes Calculated?
Unlike the federal system which uses progressive "brackets," Indiana uses a simple flat tax model for state income. Here is the breakdown of the four main taxes that eat into your gross pay:
Progressive rates from 10% to 37%. Depends heavily on your filing status and W-4.
A mandatory 7.65% flat tax for Social Security (6.2%) and Medicare (1.45%).
A flat 3.00% rate applied to your taxable income (after exemptions).
Local income tax based on your residence as of Jan 1. Ranges from ~0.5% to >3%.
Strategic Tax Planning for Indiana Residents
Maximizing your take-home pay involves understanding what you can deduct. Indiana allows several specific deductions that can lower your state tax bill:
1. Renter's Deduction
If you rent your home in Indiana, you may be eligible to deduct up to $3,000 of rent paid from your taxable income. This applies to your principal place of residence.
2. Property Tax Deduction
Homeowners can deduct up to $2,500 of property taxes paid on their principal residence. This helps offset the cost of homeownership against your state income tax liability.
3. Private School/Homeschool Deduction
Indiana offers a $1,000 deduction per qualifying child for education expenses if you homeschool or send your child to a private school. This is separate from the 529 plan credit.
4. The 529 Tax Credit
One of the most powerful tools in Indiana is the tax credit (not just a deduction) for contributions to an Indiana CollegeChoice 529 plan. You can claim a credit of 20% of your contributions, up to a maximum credit of $1,000 per year (on $5,000 contribution). This is a dollar-for-dollar reduction in your tax bill.
Deep Dive: Indiana County Income Tax Rates
Indiana is unique in that a significant portion of your income tax stays local. Your county of residence (not employment) determines your rate. As of 2024-2025, these rates vary significantly.
Highest Tax Counties (>2.5%)
Counties like Pulaski, Randolph, and Jay often have higher local option income taxes (LOIT) to fund local services, schools, and public safety. Living here means a total state+local tax burden over 5.5%.
Lowest Tax Counties (<1.0%)
Counties like Porter, Lake, and Warrick have historically kept local rates lower. For a household earning $100k, moving from a high-tax to a low-tax county can save over $1,500 annually.
Note: County rates change annually in October. Our calculator is updated to reflect the most recent Department of Revenue tables.
Indiana vs. Neighbors: The Tax Battle
How does the Hoosier state stack up against its borders? If you have the flexibility to live on either side of the state line, here is the math:
| State | Rate Type | Top Rate |
|---|---|---|
| Indiana | Flat | 3.00% (+County) |
| Illinois | Flat | 4.95% |
| Kentucky | Flat | 4.00% |
| Ohio | Progressive | ~3.5% (Top) |
| Michigan | Flat | 4.25% |
Verdict: Even with county taxes added, Indiana generally beats Illinois and Michigan on income tax, while remaining competitive with Ohio and Kentucky.
Cost of Living: It's Not Just About Taxes
While taxes are important, they must be viewed in context. Indiana consistently ranks as one of the most affordable states in the US.
The "Hoosier Arbitrage"
Many people work in higher-wage states (like Illinois) or major metro areas but live in Indiana to take advantage of the lower cost of living.
- Median Home Price (IN vs USA)~25% Lower
- Property TaxesCapped at 1% of AV
- Gas PricesBelow National Avg
Optimizing Your Withholding: The WH-4 Form
Just like the federal W-4, Indiana uses the Form WH-4 to determine how much state tax to withhold from your paycheck. Filling this out correctly is the difference between a big refund and a surprise tax bill.

Frequently Asked Questions
Why did my Indiana tax rate decrease in 2025?
Indiana passed legislation to gradually reduce the individual income tax rate. For 2025, it dropped to 3.00%. If state revenue targets are met, this rate could eventually fall to 2.9% by 2027.
Do I pay county tax where I live or where I work?
You pay county income tax based on your **county of residence** as of January 1st of the tax year. Even if you work in Indianapolis (Marion County) but live in Carmel (Hamilton County), you pay the Hamilton County rate.
Does Indiana tax 401(k) contributions?
No. Indiana generally follows the federal definition of Adjusted Gross Income (AGI). Contributions to a traditional 401(k) or 403(b) are deducted from your income before state and county taxes are calculated.
I live in Kentucky but work in Indiana. What taxes do I pay?
Indiana has a reciprocity agreement with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin. If you live in one of these states, you only pay income tax to your **home state**, not Indiana. You should file form WH-47 with your employer to stop Indiana withholding.
Are HSA contributions tax-deductible in Indiana?
Yes. Contributions to a Health Savings Account (HSA) are exempt from federal, state, and generic county income taxes, provided they are made via payroll deduction or claimed as an adjustment to income.
What is the Indiana personal exemption for 2025?
Indiana offers a $1,000 exemption for yourself, your spouse (if filing jointly), and each dependent. There are additional exemptions for being over 65 or blind ($1,000 each).
How does the tax cut affect my bi-weekly pay?
For a salary of $50,000, the 0.05% reduction saves you about $25 per year. It is small per paycheck (~$1), but combined with federal bracket adjustments, your total take-home pay should rise visibly in 2025.
Is there a local tax if I live in an unincorporated area?
Yes. In Indiana, the county tax applies to the entire county, including unincorporated areas. There are no 'tax-free' zones within a county borders.
