No, Your Bonus Is Not Taxed at a Higher Rate — It Just Looks That Way
The flat 22% withheld from most bonuses is a withholding method, not a tax rate. Why supplemental wages get special treatment on the paycheck, and how the real tax on a bonus is settled on your return like any other income.

A $5,000 bonus arrives as something like $3,500, and the office consensus forms instantly: bonuses are taxed harder than salary. They are not. On your tax return, a bonus is ordinary wages — added to the same pile, run through the same brackets. What differs is only the withholding, the estimate your employer sends ahead.
Why withholding treats bonuses specially
Regular withholding tables assume each paycheck represents your steady annual rate. Drop a bonus into that machinery and a single inflated check would be annualized — withheld as if you earned that much every period, badly overshooting. So the IRS lets employers handle supplemental wages two ways:
- The flat percentage method: withhold a flat 22% federal (higher above $1 million), plus Social Security, Medicare, and state tax. Simple, common, and the source of the famous number.
- The aggregate method: lump the bonus into a regular check and withhold by the tables — which often takes more up front, feeding the myth from the other direction.
The truth arrives in April
Whatever was withheld, the return settles the real bill. If your marginal rate is below 22%, the flat method over-withheld and the difference comes back as a refund. If you are in a higher bracket, 22% under-withheld and the return collects the rest — the bonus was never taxed at 22%; it was taxed at your rate all along.
What is actually worth doing about it
- Plan around net, not gross. If the bonus is earmarked for something, budget the after-withholding amount and treat any refund as arriving later.
- Big bonus, high bracket: check the gap. A large bonus at a 32%+ marginal rate withheld at 22% leaves a real balance due — worth covering with extra withholding before year-end.
- Bonuses still pay FICA. Social Security (below the wage base) and Medicare apply in full; no method avoids them.
- Consider where the bonus lands. Directing part of a bonus into a traditional 401(k), if your plan allows it, defers income tax on it at your top rate.
The bonus tax calculator shows both withholding methods side by side on your actual numbers — and the gap between what will be withheld and what the bonus will finally cost.
