What is a Bonus?

A bonus is additional compensation given to employees over their regular salary, often to recognize exceptional performance, company success, or tenure. While bonuses can be distributed at any time of the year, their timing and amount are generally at the employer’s discretion unless stipulated in an employment agreement.

How Bonuses Are Taxed

The Internal Revenue Service (IRS) categorizes bonuses as “supplemental wages,” subject to specific tax withholding rules separate from regular wages. Bonuses face federal income tax, Social Security, Medicare, and, potentially, state and local taxes, depending on your location. Your W-2 form will include bonuses in Box 1, showing the total wages subject to federal taxes for the year.

Federal and State Taxes on Bonuses

Both federal and, in many cases, state taxes apply to bonuses. Federal taxes are a given, but state tax requirements vary. Additionally, bonuses are subject to Social Security and Medicare taxes, and potentially unemployment taxes, depending on state laws.

Tax Withholding Methods for Bonuses

Employers have two main methods for withholding taxes on bonuses: the percentage method and the aggregate method.

The Percentage Method

This method applies a flat tax rate to bonuses. For amounts up to $1 million, a 22% federal tax rate is used. For bonuses exceeding $1 million, an additional 37% tax is applied to the excess. This method is straightforward, making it popular among employers for its simplicity.

The Aggregate Method

Under the aggregate method, bonuses are added to an employee’s regular pay, and the total amount is taxed at the employee’s regular tax rate. This method considers the employee’s filing status and allowances claimed on the W-4 form, potentially leading to more accurate withholding but also a more complex calculation process.

Minimizing the Tax Impact of Bonuses

The high tax withholding rate on bonuses often leads employees to look for ways to minimize their tax impact. Here are several strategies:

Tax Deductions and Credits

Reviewing your eligibility for tax deductions and credits can reduce your taxable income. For instance, itemizing deductions might be more beneficial if you have significant expenses like medical bills or charitable donations.

Deferring Bonuses

If possible, consider deferring your bonus to the next tax year, especially if you anticipate being in a lower tax bracket. This strategy requires careful planning and consultation with your employer and tax advisor.

Contributing to Tax-Advantaged Accounts

Contributing a portion of your bonus to a 401(k), IRA, or HSA can reduce your taxable income since these contributions are made pre-tax. However, be mindful of annual contribution limits to avoid penalties.

Adjusting Your W-4

If your tax situation has changed, updating your W-4 can ensure that your withholdings are more accurate, potentially reducing the tax burden from a bonus. Utilize the IRS Tax Withholding Estimator to make informed adjustments.


While the prospect of paying taxes on bonuses may seem daunting, understanding the rules and planning accordingly can help manage the tax impact. Both employers and employees should be aware of the tax implications of bonuses and consider strategies to mitigate their effect. By staying informed and proactive, you can enjoy the benefits of your hard work without unnecessary tax surprises.

Employers play a crucial role in withholding the correct amount of taxes on bonuses, using either the percentage or aggregate method. Employees, on the other hand, can take steps to reduce their tax liability through strategic planning and making informed decisions about their finances. Whether it’s through adjusting withholdings, deferring bonuses, or contributing to tax-advantaged accounts, there are several ways to manage the tax implications of receiving a bonus.

Remember, every individual’s tax situation is unique, so it’s advisable to consult with a tax professional to determine the best approach for managing the tax impact of your bonus. With the right strategy, you can maximize the benefits of your bonus while minimizing the tax burden.
