Understanding Bonus Taxation
How Bonuses Are Taxed
In the United States, bonuses are considered supplemental wages and are subject to special tax withholding rules. The IRS allows two methods: the percentage method (flat 22% for bonuses under $1 million) or the aggregate method (added to your regular paycheck). Either way, the actual tax owed depends on your total income and bracket at year-end. This calculator helps you estimate the net amount you will actually receive.
The Percentage Method
Most employers use the flat 22% federal withholding rate for bonuses. For bonuses exceeding $1 million, the rate jumps to 37%. Remember that withholding is not the same as your final tax bill — you may owe more or less depending on your total income, deductions, and credits when you file your return.
State Taxes on Bonuses
Most states also tax bonuses as regular income. Rates range from 0% in states like Texas, Florida, and Washington to over 13% in California. Some cities (like New York City) add additional local taxes. Your total effective tax rate on a bonus can easily exceed 30-40% in high-tax states.
401(k) and Retirement Contributions
You can often contribute a portion of your bonus to your 401(k), reducing your taxable income. If your employer allows it, directing bonus money to your 401(k) can be a smart tax strategy — you reduce current taxes while boosting retirement savings. The 2024 401(k) contribution limit is $23,000 ($30,500 if age 50+).
Smart Bonus Strategies
Consider deferring your bonus to January if you are near a tax threshold. Max out your 401(k) contribution with bonus money. If you expect a lower income next year, deferring can save significant taxes. Always consult a tax professional for personalized advice.
