How Bonus Tax Withholding Works in Ohio
Bonuses are classified as supplemental wages by the IRS and Ohio Department of Taxation. They're taxed separately from your regular paycheck using one of two methods:
| Method | How It Works | Best For |
|---|---|---|
| Flat 22% (Percentage Method) | Federal withholds exactly 22% on bonuses under $1M. Simple and predictable. | Most employees — default employer choice |
| Aggregate Method | Bonus is added to last regular paycheck, combined withholding calculated, then regular withholding subtracted. | Employees whose marginal rate differs significantly from 22% |
| Over $1 Million | 37% flat federal rate applies to the amount over $1M. | High-compensation executives |
💡 Will you get a refund? If your actual federal marginal rate is lower than 22% (common for employees earning under ~$48,475 single), you may receive some bonus withholding back when you file your tax return. If your rate is higher than 22%, you may owe additional tax.
Ohio State Bonus Withholding

Frequently Asked Questions
How are bonuses taxed in Ohio?
Bonuses are supplemental wages. Federal withholding is typically 22% flat (for bonuses under $1M). Ohio state tax is withheld at progressive rates. Municipal taxes apply in cities like Columbus (2.5%), Cleveland (2.0%), and Cincinnati (1.8%). FICA taxes also apply.
What is the aggregate method for bonus withholding?
The aggregate method adds your bonus to your most recent regular paycheck, calculates withholding on the combined amount, then subtracts the regular-period withholding. This can result in higher or lower withholding than 22% depending on your income level.
Will I get money back from my bonus withholding?
Possibly. If your annual marginal rate is below 22% (income under ~$48,475 for single filers), you may receive a refund when you file. If your rate exceeds 22%, you may owe additional tax. Withholding is just an estimate.
Are bonuses over $1 million taxed differently?
Yes. The portion of supplemental wages exceeding $1 million in a calendar year is withheld at the 37% federal flat rate. This calculator handles standard bonuses under $1 million.
