What is the Tax Rate for Bonuses? A Comprehensive Guide

When it comes to bonuses, employees often wonder about the tax implications. Are bonuses taxed differently than regular income? What is the tax rate for bonuses? In this blog post, we will provide a comprehensive guide to help you understand how bonuses are taxed and the applicable tax rates.

How are Bonuses Taxed?

When it comes to taxation, bonuses are treated as supplemental wages. The IRS considers bonuses as income separate from regular wages, which means they may be subject to different tax rates and withholding requirements.

Federal Taxation of Bonuses

Under the federal tax system in the United States, bonuses are generally subject to federal income tax withholding. The tax rate for bonuses is typically determined using one of two methods:

Percentage Method:

The percentage method is one way employers can calculate federal income tax withholding on bonuses. This method involves using a flat tax rate of 22% for supplemental wages, including bonuses, up to $1 million in a calendar year. For bonus amounts exceeding $1 million, the rate increases to 37%.

Aggregate Method:

The aggregate method, on the other hand, treats bonuses as if they were part of the employee’s regular wages. Employers combine the bonus amount with the employee’s regular wages and use the normal tax withholding tables to calculate the tax rate.

State Taxation of Bonuses

In addition to federal taxes, state taxes may also apply to bonuses. The tax treatment of bonuses varies by state, so it’s important to understand the specific rules in your state of residence.

Some states follow the federal tax system, applying the same tax rates to bonuses as they do to regular income. However, other states may have different tax rates or even unique tax laws specifically addressing bonuses. It’s crucial to consult your state’s tax authority or a tax professional to determine the applicable tax rate for bonuses in your state.

Other Considerations

While tax rates are a significant aspect of bonus taxation, it’s important to note that bonuses may also be subject to other deductions and contributions, such as:

Social Security and Medicare Taxes

Bonuses are generally subject to Social Security and Medicare taxes, just like regular wages. Employers withhold these taxes from the bonus amount.

Withholding Allowances

Employees can adjust their withholding allowances on Form W-4 to ensure the appropriate amount of taxes is withheld from their bonuses. This can help prevent underpayment or overpayment of taxes.

Supplemental Tax Rate

Some employers may choose to apply a flat supplemental tax rate to bonuses for ease of calculation. This rate is often higher than the regular tax rate and helps ensure that enough taxes are withheld from the bonus amount.


Understanding the tax rate for bonuses is essential to avoid surprises during tax season. Remember that the tax treatment of bonuses can vary depending on federal and state laws. By being aware of the applicable tax rates and other considerations, you can effectively manage your finances and ensure accurate tax withholding. Consult with a tax professional or the appropriate tax authorities to get personalized advice based on your specific situation.
