5 Legal Ways to Reduce Bonus Taxes
1. Increase 401(k) or 403(b) Contributions
Direct your bonus into pre-tax retirement contributions. Every dollar contributed reduces your taxable income dollar-for-dollar. The 2026 limit is $23,500 ($31,000 if 50+). If your bonus hits before you've maxed out, this is the most impactful move.
2. Contribute to an HSA
If you have a high-deductible health plan (HDHP), HSA contributions are pre-tax and grow tax-free. 2026 limits: $4,300 individual / $8,550 family. This gives you a triple tax advantage: deductible going in, tax-free growth, tax-free medical withdrawals.
3. Make Charitable Contributions
If you itemize deductions, charitable donations reduce your taxable income. For large bonuses, consider a donor-advised fund (DAF)—you get the full deduction this year and can distribute the funds to charities over time.
4. Adjust Your W-4 Withholding
If your bonus will be over-withheld, adjust your W-4 to claim more allowances for the rest of the year. This reduces withholding on your regular paychecks to compensate. Just remember to adjust it back next year.
5. Ask for the Percentage Method
If you're in a lower tax bracket, the flat 22% withholding may over-withhold. But if you're in the 24%+ bracket, the percentage method actually withholds less. Either way, ask your employer which method they use and if you can request the other option.
