Indiana Paycheck Calculator 2026

Indiana Payroll Tax Overview

Indiana uses a flat state income tax rate of 3.05% on all taxable wages. Unlike graduated-bracket states, every dollar you earn in Indiana above the standard deduction is taxed at the same 3.05% rate. This makes Indiana paycheck calculations straightforward and predictable.

On top of state income tax, workers in Indiana also pay federal income tax (10%–37% graduated brackets), Social Security (6.2% up to the $176,100 wage base), and Medicare (1.45%, or 2.35% above $200,000 for high earners). Pre-tax deductions like 401(k) and health insurance reduce both federal and state taxable income.

The 2026 federal income tax brackets for single filers: 10% on the first $11,925; 12% to $48,475; 22% to $103,350; 24% to $197,300; 32% to $250,525; 35% to $626,350; 37% above. Your effective federal rate will be well below the marginal rate at most income levels.

Federal vs Indiana Tax Burden

For a Indiana single filer earning $60,000 annually, estimated federal income tax is roughly $6,748 (11.2% effective), plus Indiana state tax of $1,280 (flat 3.05%), Social Security $3,720, and Medicare $870. Estimated annual take-home: approximately $47,400.

The flat tax structure means Indiana does not penalize additional income with a higher marginal state rate — every extra dollar earned is taxed at exactly 3.05% for state purposes. This can make Indiana attractive for higher earners who benefit from the predictability of a flat system.

Pre-tax 401(k) contributions, HSA contributions, and health insurance premiums reduce both federal and Indiana taxable income before tax is applied. Maximizing pre-tax deductions is one of the most effective ways to reduce your Indiana paycheck tax burden.

How to Use This Indiana Paycheck Calculator

Enter your pay period (weekly, biweekly, semimonthly, monthly, or annual), then input either your annual gross salary or your hourly rate and average hours per week. Select your federal filing status — single, married filing jointly, married filing separately, or head of household — as this determines your federal tax brackets and standard deduction.

If you have pre-tax deductions such as a 401(k) contribution, health insurance premium, or HSA contribution, enter the total per-period dollar amount. These reduce your taxable income before federal and state taxes are calculated. The calculator will show federal income tax, Social Security (6.2%), Medicare (1.45%), Indiana state income tax (3.05%), your total deductions, and your net take-home pay — both per period and annualized.

Results are estimates based on standard assumptions and 2026 tax rates. Actual withholding may differ based on your W-4 elections, additional withholding, local taxes (in some cities), or retirement plan contribution limits. For precise payroll calculations, consult your payroll provider or a tax professional.

Indiana County Income Tax (LIT) — All 92 Counties Charge

Unlike most states, ALL 92 Indiana counties add a Local Income Tax (LIT) on top of the 3.05% state rate. Rates are set by county councils and published quarterly by the Indiana Department of Revenue LIT rate table. Your county of RESIDENCE (not workplace) as of January 1 sets the LIT for the whole year:

• Marion County (Indianapolis): 2.02% LIT — combined effective 5.07% Indiana income tax.
• Lake County (Gary, Hammond): 1.50% LIT — combined 4.55%.
• Allen County (Fort Wayne): 1.59% LIT — combined 4.64%.
• Hamilton County (Fishers, Carmel): 1.10% LIT — combined 4.15%, lowest big-county rate.
• Vanderburgh County (Evansville): 1.20% LIT — combined 4.25%.
• Pulaski County (highest in state): 3.85% LIT — combined 6.90%.

Non-residents working in Indiana pay a lower non-resident LIT if their home county is elsewhere in Indiana; out-of-state workers use the workplace-county rate. A $60,000 Indianapolis resident owes roughly $1,830 state tax + $1,212 LIT = $3,042 combined Indiana income tax. Updated 2026-07-07.

Paycheck Calculator Indiana: 2026 WH-4 Form and Employer Reporting

Every Indiana employee must complete Form WH-4 at hire and after any life change (marriage, dependent added, county move). Per the Indiana Department of Revenue withholding page, the WH-4 sets both the flat 3.05% state rate and your county-of-residence LIT rate for the year. Your county on January 1, 2026 locks the LIT for all of 2026 even if you move mid-year. Run this paycheck calculator indiana with your projected 2026 gross, then confirm the total (state + county) matches the sum of Box 17 amounts on your W-2 next January. A gap larger than $200 usually means the WH-4 county code was wrong — file a corrected WH-4 for 2027 and true-up with Form IT-40 by April 15, 2027. Last updated: 2026-07-15.
