Indiana takes a flat 2.95% of your wages for the state, then adds a county income tax that ranges from 0.5% in Porter County to 3% in Randolph County. Which county applies is locked in by where you lived (or, for out-of-state residents, where you worked) on January 1.

2026 tax year, rules last verified November 12, 2026. An estimate, not tax advice. How we calculate
Each extra dollar you earn loses about 23¢ to taxes, but across all your pay the average is 19¢. A raise never lowers your take-home: only the dollars above a bracket line pay the higher rate.
| Annual pay | Effective | Marginal |
|---|---|---|
| $15,000 | 10.4% | 10.6% |
| $30,000 | 15.2% | 22.6% |
| $45,000 | 17.7% | 22.6% |
| $60,000 | 18.9% | 22.6% |
| $75,000 | 20.8% | 32.6% |
| $90,000 | 22.8% | 32.6% |
| $105,000 | 24.2% | 32.6% |
| $120,000 | 25.2% | 32.6% |
| $135,000 | 26.2% | 34.6% |
| $150,000 | 27.1% | 34.6% |
Same pay, W-4 and benefits; each state’s default withholding answers, no local taxes. Take-home per week:
Indiana uses one formula for both the state and the county tax. Your employer turns your WH-4 exemptions into a per-paycheck “deduction constant”: $1,000 a year for each line 5 exemption, $1,500 for each qualifying dependent child on lines 6 and 7, and $3,000 for each adopted child on line 8, divided by your number of paychecks.
That amount comes off your gross pay for the period. The state takes 2.95% of what is left, and your county takes its own rate of the same amount. Both show up as separate lines on your pay stub.
One-time payments such as a bonus are withheld without exemptions, so the full bonus is taxed at 2.95% plus your county rate.
Indiana follows federal treatment of pre-tax deductions, so 401(k) deferrals and Section 125 health premiums lower both the state and county tax.

All 92 Indiana counties levy a county income tax, and this calculator models every one. If you lived in Indiana on Jan. 1, use that county. If you lived in another state on Jan. 1 but your main job was in Indiana, use the county where you worked.
Indiana has no state disability, paid family leave or employee unemployment deduction. Unemployment insurance is paid by employers only.
Indiana has reciprocal agreements with Kentucky, Michigan, Ohio, Pennsylvania and Wisconsin. Residents of those states who work in Indiana can file Form WH-47 so their employer withholds no Indiana tax on those wages. Indiana residents working in those states owe Indiana and county tax at home.
With one WH-4 exemption, $19.23 comes off first. Indiana withholds 2.95% of $980.77 = $28.93, and Marion County adds 2.02% = $19.81.
The county where you lived on Jan. 1 applies for the whole year. Update your WH-4 after a move so the new county starts next Jan. 1.
Yes. If you lived outside Indiana on Jan. 1 and your principal place of work was in an Indiana county, your employer withholds that county’s rate, along with the 2.95% state tax (Illinois has no reciprocity with Indiana).
They are withheld without exemptions, so a bonus is taxed at a straight 2.95% plus your county rate. The year-end tax is the same as on regular pay.
Randolph County, at 3% for 2026. The lowest is Porter County at 0.5%.
