Why your bonus 'feels' taxed at 50%
It's not — it's withholding theater. The 22% federal + state + 7.65% FICA = ~35–40% withheld. Your true tax depends on your year-end bracket. People in the 24% bracket who see 40% withheld will get a refund. People in the 35% bracket will owe.
Route some bonus to 401k
If you're not maxed on 401(k), elect a high % from your bonus before it hits payroll. The contribution avoids federal+state income tax (saves 30%+) and grows tax-deferred. Most HR systems let you set a separate bonus elections rate.
Sign-on bonuses with clawbacks
Most sign-on bonuses are taxed when paid. If you leave early and repay the gross, you've got a problem — the IRS calls this 'claim of right' and the deduction is tricky. Negotiate net repayment OR a 12-month vesting cliff to avoid.
FAQ
Can I lower bonus withholding?
Yes — submit a fresh W-4 before the bonus pay date. Some payroll systems support 'block supplemental' or use aggregate method which applies your normal withholding rate.
Are bonuses taxed differently than salary?
No — at year-end they're all ordinary income at the same rates. Only the withholding method differs (supplemental flat vs. wage-bracket).
Do bonuses count toward 401(k) match?
Depends on the plan. Many plans match the % election from any cash compensation including bonuses; some exclude bonuses. Check your SPD.
