Indiana Paycheck Calculator

The Indiana Paycheck Calculator estimates your take-home pay after federal income taxes, Indiana state income tax at a flat 3.05% rate, mandatory county income tax, and FICA contributions. Indiana is unique among US states in that every one of its 92 counties imposes its own income tax on top of the state rate. County tax rates range from 0.5% to 2.96%, meaning your total state-plus-county income tax burden ranges from approximately 3.55% to 5.97% depending on your county of residence. Indiana's flat 3.05% state rate is one of the lowest flat rates in the nation. However, the mandatory county tax adds a significant and variable layer that makes Indiana's total tax burden comparable to or higher than some neighboring states with higher headline state rates. The county tax is based on your county of residence, not your county of employment. This means that two workers sitting next to each other at the same workplace in Indianapolis may pay different county rates if they live in different counties. Indiana's personal exemption is $1,000 per person, plus additional exemptions for dependents ($1,500 per qualifying child). The state does not use a standard deduction; it starts with federal AGI and adjusts using Indiana-specific additions and deductions. Indiana conforms to many federal tax provisions, and pre-tax retirement contributions reduce Indiana taxable income. This calculator is essential for Indiana workers because the county tax makes a significant difference in take-home pay. A worker in Marion County (Indianapolis, 2.02%) pays approximately $1,300 more annually in county tax than a worker in the same income bracket living in a county with a 0.5% rate. The calculator is used by employees, employers, workers deciding where to live in Indiana, and financial planners helping clients optimize their county-dependent tax situation.

1. 1Enter your gross pay amount, pay frequency, and your county of residence. Your county of residence determines your county tax rate, which is a critical input for Indiana paycheck calculations. Indiana has 92 counties, each with its own tax rate set by the county council. Rates change periodically, so verify the current rate for your county. Your gross pay includes salary, overtime, bonuses, and other compensation.
2. 2Federal income tax is calculated based on your W-4 elections using 2024 brackets from 10% to 37%. Pre-tax deductions reduce federal taxable income. Indiana's major employers include Eli Lilly, Cummins, Anthem, Salesforce (Indianapolis tower), the auto industry, and significant military installations (Naval Surface Warfare Center Crane, Grissom Air Reserve Base).
3. 3Indiana state income tax is calculated at the flat 3.05% rate on your Indiana adjusted gross income minus exemptions. Indiana starts with federal AGI and makes state-specific adjustments. Personal exemptions of $1,000 per taxpayer and $1,500 per qualifying child further reduce the tax base. The flat rate means every additional dollar of taxable income generates exactly 3.05 cents in state tax.
4. 4County income tax is calculated based on your county of residence at the applicable rate. The county rate applies to the same income base as the state tax. For example, a Marion County resident earning $80,000 with $3,000 in exemptions pays county tax of ($80,000 - $3,000) x 2.02% = $1,555.40 annually. The same worker living in Hamilton County would pay ($80,000 - $3,000) x 1.0% = $770, saving $785 per year simply by living in a different county.
5. 5FICA taxes are calculated at standard federal rates. Indiana has no additional state payroll taxes beyond the income and county taxes. There is no state disability insurance, paid family leave, or similar mandatory deduction.
6. 6The calculator totals all deductions. Your pay stub will typically show the state tax and county tax as separate line items. Some employers combine them into a single state/local tax line. Either way, both must be correctly calculated based on your county of residence.
7. 7Compare take-home pay across counties. If you work in Indianapolis but are choosing between living in Marion County (2.02% county tax), Hamilton County (1.0%), or Hendricks County (1.5%), the county tax difference can amount to hundreds or thousands of dollars annually. This makes county selection an important financial consideration when buying or renting a home in Indiana.

• !Using Work County Instead of Residence County for Tax Rate: Indiana county income tax is based on your county of residence, not where you work. A worker living in Hendricks County but commuting to Indianapolis (Marion County) pays the Hendricks County rate, not the Marion County rate. This is a frequent source of error, particularly for workers who recently moved between counties. Ensure your employer has your correct home address on file to apply the right county rate.
• !Not Accounting for Significant County Rate Variations: Indiana's 92 counties have tax rates ranging from 0.5% to 2.96%. The difference between the lowest and highest county rates is 2.46 percentage points, which on a $75,000 salary amounts to approximately $1,845 per year. Workers who do not factor in county tax when evaluating job offers or housing decisions may be surprised by their actual take-home pay. Always include the specific county rate in your calculations.
• !Overlooking County Tax Rate Changes: Indiana counties can change their tax rates annually through county council action. Rates typically change on October 1 each year. If your county recently adjusted its rate, your employer may take several pay periods to update withholding to the new rate. Check the Indiana Department of Revenue website for the most current county tax rate table.
