IRS Publication 15 (2026), section 7: add the bonus to a regular paycheck, work out withholding on the total as if it were one paycheck, and subtract what the regular paycheck alone has withheld. In the aggregate column the Indiana figure uses the state's regular withholding formula the same way. State payroll programs (disability, paid leave, local taxes) are included in both columns.

How Indiana withholds on a bonus

Indiana withholds 2.95% state tax plus your county rate on the whole bonus, without exemptions. That's what the calculator's flat column shows.

Indiana adds county income tax on the whole bonus, at your county's rate. The figures on this page leave it out; enter your county rate in the calculator above.

If the bonus is paid on the same check as your regular pay without the amounts shown separately, the employer withholds on the total as one paycheck — the aggregate column. That can take more or less than the flat method: the payroll formula treats the bigger paycheck as if you earned it every pay period, so larger bonuses usually have more withheld. Either way, any excess comes back when you file your 2026 return.
