What is Bonus Tax?
Bonus tax refers to the income taxes withheld from a bonus payment. Unlike regular salary, bonuses are often taxed at a flat rate or a higher marginal rate because they are considered supplemental income. Understanding how bonus tax is calculated is crucial for accurately estimating the net amount you'll receive. This calculation involves considering your total income, tax filing status, and the applicable tax brackets. Many employees are surprised by the amount of tax deducted from their bonus, making it essential to plan accordingly. This guide will help you navigate the complexities of bonus taxation and provide tools to estimate your net bonus.
Bonus Tax Formula and Mathematical Explanation
The calculation of bonus tax primarily involves determining the marginal tax rate that applies to the bonus amount. In the United States, supplemental wages like bonuses are typically subject to federal income tax withholding at a flat rate of 22% up to $1 million. However, if the bonus is paid separately from regular wages, or if the employer chooses, the bonus can be taxed as if it were part of your regular income, meaning it falls into your marginal tax bracket. This calculator uses the latter method for a more personalized estimate, as it reflects your actual tax situation more closely. The formula can be simplified as:
This is equivalent to calculating the tax on your total income (including the bonus) and subtracting the tax on your income without the bonus. The marginal tax rate is determined by your total annual income and your tax filing status. For example, if your annual income places you in the 24% tax bracket, and you receive a bonus, that bonus will likely be taxed at 24% (plus FICA taxes, which are separate). Our calculator estimates this marginal rate based on provided annual income and filing status. Remember, this calculation focuses on federal income tax; state and local taxes may also apply and vary significantly.
Practical Examples (Real-World Use Cases)
Let's illustrate with a few scenarios:
Scenario 1: Single Filer with Moderate Income
Sarah is single and earns $70,000 annually. She receives a $5,000 gross bonus. Her income places her in the 22% federal tax bracket. The calculator estimates that her $5,000 bonus will be taxed at 22%, resulting in approximately $1,100 in federal income tax. Her net bonus is around $3,900.
Scenario 2: Married Couple with Higher Income
John and Jane are married, filing jointly, with a combined annual income of $150,000. They receive a $10,000 gross bonus. This income level places them in the 24% federal tax bracket. The calculator estimates that their $10,000 bonus will be taxed at 24%, leading to about $2,400 in federal income tax. Their net bonus is approximately $7,600.
Scenario 3: Bonus Pushing into a Higher Bracket
Michael earns $115,000 annually as a single filer. He receives a $15,000 bonus. His current income falls into the 24% tax bracket. However, adding the $15,000 bonus pushes his total income to $130,000, which is still within the 24% bracket for single filers in 2023. The calculator would apply the 24% rate. If the bonus had pushed him into the next bracket (e.g., 32%), the calculation would reflect that higher marginal rate on the portion of the bonus falling into that bracket. This highlights the importance of understanding your position relative to tax brackets.

Key Factors That Affect Bonus Tax Results
Several factors influence the amount of tax deducted from your bonus:
Marginal Tax Bracket: This is the most significant factor. The higher your income, the higher your marginal tax rate, and thus, the more tax will be withheld from your bonus. Our calculator uses your annual income and filing status to estimate this.
Tax Filing Status: Different filing statuses (Single, Married Filing Jointly, etc.) have different tax brackets and standard deductions, affecting the marginal rate applied to your bonus.
Supplemental Wage Withholding Rules: Employers have options for withholding taxes on bonuses. While the flat 22% rate is common, some employers calculate it based on your regular wage bracket, which this calculator estimates.
State and Local Taxes: This calculator focuses on federal income tax. Many states and some localities also impose income taxes, which will further reduce your net bonus. These rates vary widely.
Other Income and Deductions: While we use your stated annual income, other income sources or specific deductions you claim could shift your overall tax situation, though this calculator provides a solid estimate based on the inputs.
FICA Taxes: Social Security and Medicare taxes (FICA) are also withheld from bonuses. These are separate from income tax. Social Security tax is 6.2% up to an annual wage limit ($168,600 in 2024), and Medicare tax is 1.45% with no limit. These are not included in the income tax calculation but reduce the take-home amount.
Frequently Asked Questions (FAQ)
Why is my bonus taxed so heavily?
Bonuses are considered supplemental income and are often taxed at your highest marginal income tax rate. Additionally, they are subject to FICA taxes (Social Security and Medicare). This combination can lead to a significant portion being withheld.
Is the bonus tax rate different from my regular income tax rate?
It can be. Some employers use a flat withholding rate (e.g., 22% federally) for bonuses. Others calculate it based on your regular pay, effectively taxing the bonus at your marginal income tax rate. This calculator estimates based on your marginal rate.
Does the calculator include state and local taxes?
No, this calculator focuses on federal income tax withholding. State and local income taxes vary significantly and are not included in this estimate. You'll need to consider those separately based on your location.
What are FICA taxes?
FICA stands for the Federal Insurance Contributions Act. It funds Social Security and Medicare. Both employees and employers contribute. For employees, the rates are 6.2% for Social Security (up to an annual limit) and 1.45% for Medicare (no limit). These apply to bonuses as well.
Can I adjust my withholding to account for a bonus?
Yes, you can submit a new Form W-4 to your employer to adjust your federal income tax withholding throughout the year. This can help ensure you aren't over or under-withheld, especially if you anticipate large bonuses or other income changes.
