How to Use This Tool
This Indiana payroll calculator accounts for the state's unique two-tier system of flat state tax plus county income tax. Here is how to get precise results:
- Enter your annual gross salary in the first field. If you know your hourly rate, multiply by 2,080 (40 hours times 52 weeks) for a full-time annual equivalent.
- Choose your pay frequency. Biweekly (26 pay periods) is most common in Indiana, but you can select weekly, semi-monthly, monthly, or annual to see the correct per-period amounts.
- Select your filing status from your W-4 form. Single, Married Filing Jointly, and Head of Household each produce different federal tax amounts. Indiana's flat state rate does not change with filing status, but the personal exemption calculation may differ.
- Choose your county of residence. This is critical for Indiana because all 92 counties impose local income taxes ranging from 0.5% to 3.38%. The county where you live (not where you work) determines your county tax rate. If your county is not listed, select "Other County" with the average 1.50% rate and note that your actual rate may differ.
- Add any extra withholding or pre-tax deductions as needed. Pre-tax deductions like 401(k) contributions reduce both federal and Indiana state taxable income.
- Press Calculate to see your full breakdown with per-period amounts, annual totals, effective rate, and visual chart.
Indiana State Tax Rate
Indiana imposes a flat state income tax rate of 3.05% on Indiana adjusted gross income for the 2024 tax year. This is one of the lowest flat state income tax rates in the country, behind only Pennsylvania (3.07% -- though that rate is actually slightly higher), North Dakota, and a few others.
Indiana's flat rate has been gradually declining. It was 3.40% for tax years 2015 through 2016, dropped to 3.23% from 2017 through 2022, and was reduced to 3.15% for 2023 before reaching the current 3.05% for 2024. The Indiana legislature has targeted further reductions with the goal of reaching 2.9% by 2027, contingent on state revenue targets being met.
| Tax Year | Indiana Flat Rate | Personal Exemption |
|---|---|---|
| 2024 | 3.05% | $1,000 per person |
| 2023 | 3.15% | $1,000 per person |
| 2022 | 3.23% | $1,000 per person |
| 2021 | 3.23% | $1,000 per person |
| 2020 | 3.23% | $1,000 per person |
Indiana uses a personal exemption system rather than a standard deduction for state purposes. Each taxpayer and their spouse receive a $1,000 exemption, dependents get $1,500 each, and additional $1,000 exemptions apply for taxpayers who are blind or over age 65. These exemptions reduce Indiana adjusted gross income before the 3.05% flat rate applies.
However, what makes Indiana's tax situation unique is the mandatory county income tax that applies on top of the state rate. When you add the county tax (averaging about 1.5% but reaching as high as 3.38%), the combined state and local income tax rate ranges from about 3.55% to 6.43%, which changes the overall picture considerably.
Indiana County Tax Rates
Indiana is one of only a few states where every county imposes its own income tax. These county taxes are administered by the Indiana Department of Revenue and collected through employer withholding, just like the state tax. The tax is based on the county where you reside, not where you work.
Here are the county tax rates for the most populated counties and some notable outliers:
| County | Major City | County Tax Rate | Combined State + County |
|---|---|---|---|
| Marion | Indianapolis | 2.02% | 5.07% |
| Allen | Fort Wayne | 1.77% | 4.82% |
| Lake | Gary, Hammond | 1.25% | 4.30% |
| Hamilton | Carmel, Fishers, Noblesville | 2.50% | 5.55% |
| St. Joseph | South Bend, Mishawaka | 1.50% | 4.55% |
| Tippecanoe | Lafayette, West Lafayette | 1.50% | 4.55% |
| Vanderburgh | Evansville | 1.00% | 4.05% |
| Monroe | Bloomington | 1.50% | 4.55% |
| Elkhart | Elkhart, Goshen | 1.48% | 4.53% |
| Johnson | Greenwood, Franklin | 1.59% | 4.64% |
| Hendricks | Plainfield, Avon | 1.25% | 4.30% |
| Porter | Valparaiso, Portage | 1.00% | 4.05% |
| Howard | Kokomo | 2.10% | 5.15% |
| Delaware | Muncie | 1.75% | 4.80% |
| Vigo | Terre Haute | 1.50% | 4.55% |
| Clark | Jeffersonville | 1.00% | 4.05% |
| Wayne | Richmond | 2.00% | 5.05% |
| Pulaski | Winamac | 3.38% | 6.43% |
| Adams | Decatur | 2.87% | 5.92% |
| Jasper | Rensselaer | 2.71% | 5.76% |
| LaPorte | Michigan City | 0.50% | 3.55% |
County tax rates are set by each county's government body and can change annually. The Indiana Department of Revenue publishes the official list of county income tax rates each year in Departmental Notice #1. If you move from one county to another during the year, your county tax is prorated based on the number of days you lived in each county.
The county where you reside on January 1 of the tax year generally determines your county tax rate for the entire year for withholding purposes. If you move mid-year, you should update your WH-4 form with your employer to ensure the correct county rate is being withheld.
2024 Federal Tax Brackets
All Indiana residents also pay federal income tax. The 2024 federal tax brackets use marginal rates, meaning each rate applies only to income within that specific range:
Single Filers
| Taxable Income Range | Tax Rate | Tax on Range |
|---|---|---|
| $0 to $11,600 | 10% | Up to $1,160 |
| $11,601 to $47,150 | 12% | Up to $4,266 |
| $47,151 to $100,525 | 22% | Up to $11,742 |
| $100,526 to $191,950 | 24% | Up to $21,942 |
| $191,951 to $243,725 | 32% | Up to $16,568 |
| $243,726 to $609,350 | 35% | Up to $127,969 |
| Over $609,350 | 37% | Varies |
Married Filing Jointly
| Taxable Income Range | Tax Rate |
|---|---|
| $0 to $23,200 | 10% |
| $23,201 to $94,300 | 12% |
| $94,301 to $201,050 | 22% |
| $201,051 to $383,900 | 24% |
| $383,901 to $487,450 | 32% |
| $487,451 to $731,200 | 35% |
| Over $731,200 | 37% |
For 2024, the federal standard deduction is $14,600 for single filers, $29,200 for married filing jointly, and $21,900 for head of household. Full details are in IRS Revenue Procedure 2023-34.
FICA Tax Breakdown
FICA taxes apply uniformly to all Indiana W-2 employees:
| FICA Component | Employee Rate | Wage Base (2024) | Max Annual Employee Cost |
|---|---|---|---|
| Social Security (OASDI) | 6.2% | $168,600 | $10,453.20 |
| Medicare (HI) | 1.45% | No limit | No cap |
| Additional Medicare | 0.9% | Over $200,000 (single) | Varies |
Your employer matches the 6.2% Social Security and 1.45% Medicare amounts. For a $55,000 salary, FICA costs $3,410 for Social Security and $797.50 for Medicare, totaling $4,207.50 annually. Combined with Indiana's flat 3.05% state tax and an average county rate of 1.5%, the total payroll deduction rate before federal income tax is approximately 12.2%. Federal income tax adds another layer depending on your bracket.
Indiana's combined state and local income tax burden plus FICA typically ranges from 18% to 30% depending on income level and county, making it one of the more moderate total tax states in the Midwest.
Paycheck Examples by Salary
Here are sample take-home pay calculations for common salary levels in Indiana. These assume single filing status, biweekly pay, Marion County (2.02%), federal standard deduction, no additional withholding, and no pre-tax deductions:
| Annual Salary | Federal Tax | IN State + County | FICA | Annual Net Pay | Biweekly Net |
|---|---|---|---|---|---|
| $30,000 | $1,668 | $1,471 | $2,295 | $24,566 | $945 |
| $40,000 | $2,868 | $1,978 | $3,060 | $32,094 | $1,234 |
| $50,000 | $4,068 | $2,484 | $3,825 | $39,623 | $1,524 |
| $55,000 | $4,668 | $2,738 | $4,208 | $43,386 | $1,669 |
| $65,000 | $6,468 | $3,244 | $4,973 | $50,315 | $1,935 |
| $75,000 | $8,068 | $3,751 | $5,738 | $57,443 | $2,209 |
| $85,000 | $9,868 | $4,257 | $6,503 | $64,372 | $2,476 |
| $100,000 | $13,118 | $5,017 | $7,650 | $74,215 | $2,854 |
| $125,000 | $19,118 | $6,284 | $9,563 | $90,035 | $3,463 |
| $150,000 | $25,918 | $7,551 | $11,475 | $105,056 | $4,041 |
Indiana's low flat state rate means that for a $55,000 earner in Marion County, the combined state and county tax of about $2,738 is notably lower than what the same earner would pay in Oregon ($4,845 state tax) or even Colorado ($2,218 state tax only, but Colorado has no county income tax). However, the county tax adds a layer that other flat-rate states do not have.
If you live in a low-rate county like LaPorte (0.50%), your combined state and county burden drops to about 3.55%, while Pulaski County (3.38%) pushes the combined rate to 6.43%. This difference of nearly 3 percentage points means a $55,000 earner in Pulaski County pays roughly $1,600 more per year in state and local income tax than the same earner in LaPorte County.
Common Deductions Guide
Here is a guide to the deductions you will see on your Indiana paycheck:
Mandatory Deductions
- Federal Income Tax: Withheld per your W-4. The largest variable deduction for most Indiana workers.
- Indiana State Income Tax: Flat 3.05% of Indiana adjusted gross income. Employers withhold this using the WH-4 form information.
- County Income Tax: The rate for your county of residence, withheld by your employer. You must complete the county section of the Indiana WH-4 form.
- Social Security: 6.2% of gross wages up to $168,600.
- Medicare: 1.45% of all gross wages. Additional 0.9% applies above $200,000 (single).
Common Pre-Tax Deductions
- 401(k) / 403(b): Reduce federal and Indiana state taxable income. 2024 limit: $23,000 ($30,500 if 50+). Indiana follows federal treatment for qualified retirement plans.
- Health insurance premiums: Employer-sponsored plan contributions are typically pre-tax for all purposes.
- HSA contributions: Pre-tax through payroll. Indiana conforms to federal HSA treatment. 2024 limits: $4,150 individual, $8,300 family.
- FSA contributions: Reduce taxable income. 2024 medical FSA limit: $3,200.
Post-Tax Deductions
- Roth 401(k) contributions: After-tax, no current tax benefit but tax-free growth.
- Wage garnishments: Indiana follows federal guidelines for maximum garnishment amounts.
- Union dues: Applicable for unionized workplaces, particularly in manufacturing.
Pre-tax deductions reduce your Indiana state tax, county tax, and federal tax simultaneously. A $500 monthly 401(k) contribution saves approximately $15.25 in state tax, $10.10 in county tax (Marion), and your federal marginal rate savings per month.
Indiana Department of Revenue
The Indiana Department of Revenue (DOR) administers state and county income tax collection. Key information for Indiana taxpayers:
- Form IT-40: Indiana individual income tax return for full-year residents. Due April 15.
- Form WH-4: Indiana's employee withholding exemption and county status certificate. This form tells your employer your county of residence and personal exemptions for state withholding purposes.
- County tax administration: Although county taxes are levied by local governments, the Indiana DOR collects them through the state income tax return and employer withholding system, then distributes the revenue to counties.
- INtax system: Indiana's online filing and payment portal for individual and business taxes.
- Estimated payments: Required if you expect to owe $1,000 or more in combined state and county tax. Payments are due April 15, June 15, September 15, and January 15.
Indiana has a reciprocal tax agreement with several neighboring states. If you live in Indiana but work in Kentucky, Michigan, Ohio, Pennsylvania, or Wisconsin, your employer in those states should not withhold their state tax from your wages. Instead, you pay Indiana state and county tax on those wages. Conversely, if you live in one of those states and work in Indiana, your Indiana employer should withhold your home state's tax. This avoids the complexity of filing in two states for most cross-border workers.
The IRS and Indiana DOR coordinate on information sharing, so consistency between your federal and Indiana returns is important.
Indiana vs Other States
How does Indiana's tax picture compare to nearby states? The low flat rate is appealing, but county taxes change the equation:
| State | Income Tax | Top Rate | Local Income Tax? | Sales Tax |
|---|---|---|---|---|
| Indiana | Flat | 3.05% + county | Yes (all 92 counties) | 7% |
| Illinois | Flat | 4.95% | No | 6.25%+ |
| Ohio | Progressive | 3.75% | Yes (many cities) | 5.75%+ |
| Michigan | Flat | 4.25% | Yes (some cities) | 6% |
| Kentucky | Flat | 4.0% | Yes (some counties) | 6% |
| Wisconsin | Progressive | 7.65% | No | 5%+ |
| Iowa | Progressive | 5.7% | No (eliminated) | 6%+ |
| Tennessee | None | 0% | No | 7%+ |
Indiana's combined state and county rate in most areas (4% to 5.5%) is competitive with neighboring states. The effective rate in Marion County (5.07%) is comparable to Illinois' flat 4.95% but with the added benefit of Indiana's lower cost of living. Hamilton County's higher 5.55% combined rate reflects the funding needs of one of Indiana's fastest-growing suburban areas.
Indiana's 7% sales tax rate is among the highest in the region, partially offsetting the income tax advantage. However, Indiana exempts most grocery food from sales tax, which helps lower-income households.
Indiana Cost of Living
Indiana consistently ranks as one of the most affordable states in the country for cost of living. Housing costs in particular are well below national averages across most of the state:
| Indiana City/Region | Cost of Living Index | Median Home Price (2024) | $55K Salary Feels Like |
|---|---|---|---|
| Indianapolis Metro | 92 | $280,000 | $59,800 |
| Fort Wayne | 82 | $215,000 | $67,100 |
| Carmel / Fishers | 105 | $420,000 | $52,400 |
| Bloomington | 93 | $275,000 | $59,100 |
| South Bend | 81 | $190,000 | $67,900 |
| Evansville | 83 | $195,000 | $66,300 |
| Lafayette | 86 | $225,000 | $64,000 |
| Muncie | 78 | $145,000 | $70,500 |
| Terre Haute | 80 | $155,000 | $68,800 |
The "feels like" column shows the purchasing power of a $55,000 salary compared to the national average (100). In Fort Wayne, your $55,000 stretches to the equivalent of $67,100, making it one of the most affordable mid-size cities in the Midwest. Even the Indianapolis metro area is 8% below the national average cost of living.
According to Bureau of Labor Statistics data, Indiana's housing costs are about 20-30% below the national median, while healthcare, transportation, and food costs are close to or slightly below average. The Carmel/Fishers corridor is the notable exception, where housing costs approach or exceed national averages, driven by demand for high-quality schools and suburban amenities.
Tax Saving Tips for IN Workers
Indiana workers can take advantage of several strategies to reduce their overall tax burden:
- 401(k) contributions. The 2024 limit is $23,000 ($30,500 if 50+). At Indiana's combined state and county rate of about 5% (Marion County), a $23,000 contribution saves you roughly $1,150 in state and county tax alone, plus your federal savings.
- Fund your HSA. If eligible, contribute the maximum ($4,150 individual, $8,300 family). HSA contributions through payroll reduce federal, state, county, and FICA taxes. Triple tax advantage makes HSAs one of the best savings vehicles for Indiana workers.
- Claim all eligible personal exemptions. Indiana's $1,000 per-person and $1,500 per-dependent exemptions directly reduce your state taxable income. Make sure your WH-4 form accurately reflects all exemptions you qualify for.
- Use the Indiana CollegeChoice 529 deduction. Indiana offers a state tax credit of 20% of contributions to the CollegeChoice 529 plan, up to a maximum credit of $1,500 per year. This is one of the most generous 529 benefits in the country since it is a credit (dollar-for-dollar reduction in tax) rather than just a deduction.
- Claim the Indiana Earned Income Credit. If you qualify for the federal EITC, Indiana provides a state credit equal to 10% of your federal credit. This is refundable, meaning it can reduce your Indiana tax below zero.
- Consider your county of residence carefully. If you are adaptable on where you live, the county tax difference can be significant. Living in LaPorte County (0.50%) versus Pulaski County (3.38%) saves $1,584 per year on a $55,000 income. Even within the Indianapolis metro area, Hendricks County (1.25%) is notably cheaper than Hamilton County (2.50%).
- Take advantage of the Unified Tax Credit for the Elderly. Indiana residents age 65 or older with federal adjusted gross income under $10,000 may qualify for a credit of up to $140 against their Indiana tax liability.
- Track charitable contributions. While Indiana does not offer a separate state deduction for charitable giving beyond what reduces your federal AGI, Indiana does offer a credit for contributions to qualifying Indiana educational institutions and community foundations.
Self-Employment Tax in Indiana
Self-employed workers in Indiana pay both the employee and employer shares of FICA, plus Indiana state and county income tax. Here is a quick calculator:
Self-Employment Tax Breakdown
Key considerations for self-employed workers in Indiana:
- Self-employment tax: 15.3% on 92.35% of net SE income (12.4% Social Security + 2.9% Medicare). The Social Security portion caps at $168,600.
- Deductible half: Half of your SE tax is deductible as an above-the-line deduction, reducing both federal and Indiana taxable income.
- Quarterly estimated payments: Required for both federal (Form 1040-ES) and Indiana (Form IT-40ES) if you expect to owe $1,000 or more. County tax is also paid through estimated payments.
- Indiana county tax applies: Self-employed individuals owe county tax based on their county of residence, just like W-2 employees.
- QBI deduction: The Section 199A qualified business income deduction of up to 20% reduces both federal and Indiana taxable income for qualifying self-employment income.
- Business expense deductions: All legitimate business expenses reduce your net SE income before any state, county, or federal tax calculations.
Indiana Salaries by Industry
Indiana's economy is anchored by manufacturing, logistics, healthcare, agriculture, and a growing technology sector. Here are average salaries by industry with estimated take-home pay for single filers in Marion County:

| Healthcare (RN) | $68,000 | $52,400 | $2,015 |
| Logistics / Distribution | $48,000 | $38,200 | $1,469 |
| Information Technology | $82,000 | $62,000 | $2,385 |
| Education (K-12 Teacher) | $52,000 | $41,200 | $1,585 |
| Agriculture / Agribusiness | $42,000 | $34,000 | $1,308 |
| Financial Services / Insurance | $72,000 | $55,000 | $2,115 |
| Government (State) | $50,000 | $39,600 | $1,523 |
| Construction / Skilled Trades | $55,000 | $43,400 | $1,669 |
| Steel / Heavy Manufacturing | $65,000 | $50,400 | $1,938 |
| Life Sciences Research | $78,000 | $59,400 | $2,285 |
Indianapolis serves as a major hub for pharmaceutical companies (Eli Lilly is headquartered there), insurance companies, motorsports, and logistics. The state's central location and strong interstate highway system make it a natural distribution center. Manufacturing remains a significant part of Indiana's economy, with automotive plants, steel mills, and RV production (Elkhart County is the RV capital of the world) providing thousands of well-paying jobs.
Indiana's minimum wage follows the federal minimum of $7.25 per hour, though many employers pay well above this. The median household income in Indiana is approximately $62,000, below the national median of $75,000 but offset by the state's notably lower cost of living.

Frequently Asked Questions
What is the Indiana state income tax rate?
Indiana has a flat state income tax rate of 3.05% for the 2024 tax year. This rate applies to all levels of Indiana adjusted gross income. The state has been gradually reducing this rate and may lower it further to 2.9% by 2027 if revenue targets are met.
How do Indiana county taxes work?
All 92 Indiana counties impose their own local income tax on residents. The tax is based on the county where you live, not where you work. Your employer withholds county tax based on the county information you provide on your Indiana WH-4 form. Rates range from 0.50% (LaPorte County) to 3.38% (Pulaski County), with most falling between 1% and 2%.
What is the Marion County (Indianapolis) tax rate?
Marion County, which encompasses Indianapolis, has a county income tax rate of 2.02% for 2024. Combined with the 3.05% state rate, Indianapolis residents pay a total state and local income tax rate of 5.07%.
Does Indiana have a standard deduction?
No, Indiana uses a personal exemption system instead of a standard deduction for state tax purposes. You receive a $1,000 exemption for yourself and your spouse, $1,500 for each dependent, and additional $1,000 exemptions for being over 65 or blind. These exemptions reduce your Indiana adjusted gross income before the flat 3.05% rate applies. Note that for federal taxes, you still use the federal standard deduction.
Does Indiana tax Social Security benefits?
No. Indiana fully exempts Social Security benefits from state and county income tax. This applies regardless of your total income level. Other retirement income, such as pensions and 401(k) distributions, is generally taxable at the flat 3.05% state rate plus your county rate.
What is Indiana's reciprocal agreement?
Indiana has reciprocal tax agreements with Kentucky, Michigan, Ohio, Pennsylvania, and Wisconsin. If you live in Indiana and work in one of these states, your employer should withhold Indiana tax (not the work state's tax). This prevents you from having to file in two states. The agreement works both ways for residents of those states working in Indiana.
Can I change my county on my WH-4?
Yes. If you move to a different county, you should file a new WH-4 form with your employer to update your county of residence. Your employer will then adjust the county tax withholding rate to match your new county. This ensures you are not over- or under-withheld for county tax during the year.
Is the 529 CollegeChoice credit worth it in Indiana?
The Indiana CollegeChoice 529 plan offers a 20% state tax credit on contributions up to $7,500 per year (maximum credit of $1,500). This is a dollar-for-dollar reduction in your Indiana tax liability, making it one of the best 529 incentives in the country. If you have children and plan to fund education expenses, contributing to CollegeChoice is almost always financially beneficial for Indiana taxpayers.
