Yes. Indiana treats bonuses as taxable wages and requires Indiana income tax withholding on bonus and other supplemental wage payments. Indiana uses a flat state income tax rate, which makes bonus withholding more straightforward compared to states with progressive tax systems. In addition to the state tax, many employees are also subject to county income tax, which varies based on the employee’s county of residence and/or principal place of work.
When a bonus is paid, Indiana withholding is generally calculated using the same flat rate that applies to regular wages, along with any applicable county tax. You can use the calculator above, powered by Beyond, to estimate Indiana withholding and take-home pay for bonus payments. The calculator uses a 2026 estimate based on Indiana withholding rules and current payroll assumptions.
How to Calculate Bonus Tax in Indiana
Supplemental wages—including bonuses, commissions, overtime pay, back pay, and certain additional wage payments—are generally treated as wages for withholding purposes.
For Indiana state and county withholding:
– Paid separately from regular wages: withholding is typically calculated using the Indiana flat state income tax rate of 2.95%, plus any applicable county tax rate
– Paid together with regular wages: withholding may be calculated on the total combined wages for the payroll period
– County tax rates vary and may change, so actual withholding depends on the employee’s county and payroll setup
For federal withholding:
– 22% applies to most supplemental wages
– 37% applies to supplemental wages above $1 million in a calendar year
