The satisfaction of receiving a year-end bonus may soon be tempered by the realization that income taxes will have to be paid on the extra money. Bonuses are treated as income and thus subject to taxation, but there are ways to manage and reduce the amount of taxes that will be owed. As is the case with other income from an employer, the employer is required to withhold taxes from a bonus, reducing your take-home pay from the windfall.
A financial advisor can potentially help you optimize your tax strategy for a bonus.
How Are Bonuses Taxed?
Bonuses are considered supplemental wages, which means their taxes are withheld differently than your regular paycheck. Employers typically use one of two IRS-approved methods to withhold taxes: the percentage method or the aggregate method. Under the percentage method, your bonus is subject to a flat federal withholding rate of 22% for most bonuses, which can make the tax bite feel larger upfront, even if your overall tax liability ends up lower when you file your return.
With the aggregate method, your employer adds your bonus to your most recent paycheck and withholds taxes based on your normal income tax bracket. This approach can push the combined amount into a higher bracket for that pay period, resulting in higher withholding on that specific paycheck.
Either way, it’s important to remember that withholding is not the same as the actual tax you owe. The amount withheld is an estimate, and your final tax bill is determined when you file your return. Depending on your deductions, credits and total income for the year, you may receive a refund or owe additional tax.

About This Calculator
Our income tax calculator calculates your federal, state and local taxes based on several key inputs: your household income, location, filing status and number of personal exemptions.
How Income Taxes Are Calculated
-
First, we calculate your adjusted gross income (AGI) by taking your total household income and reducing it by certain items such as contributions to your 401(k).
-
Next, from AGI we subtract exemptions and deductions (either itemized or standard) to get your taxable income. Exemptions can be claimed for each taxpayer.
-
Based on your filing status, your taxable income is then applied to the tax brackets to calculate your federal income taxes owed for the year.
-
Your location will determine whether you owe local and / or state taxes.
When Do We Update? - We check for any updates to the latest tax rates and regulations annually.
Customer Service - If you would like to leave any feedback, feel free to email info@smartasset.com.
Assumptions
Deductions
- "Other Pre-Tax Deductions" are not used to calculate state taxable income.
Credits
- The only federal credit automatically calculated is the Savers Credit, depending on your eligibility.
- We do not apply any refundable credits, like the Child Tax Credit or Earned Income Tax Credit (EITC).
- We do not apply state credits in our calculations.
Itemized Deductions
- If itemizing at the federal level, you may need to itemize at the state level too. Some states don't allow itemized deductions, which is accounted for in our calculations.
- When calculating the SALT deduction for itemized deductions, we use state and local taxes, and we assume your MAGI.
- We assume that there is no cap to itemized deductions, if a state allows them.
- We do not categorize itemized deductions (such as medical expenses or mortgage interest), which could be subject to specific caps per state.
Local Tax
- Depending on the state, we calculate local taxes at the city level or county level. We do not include local taxes on school districts, metro areas or combine county and city taxes.
- With the exception of NYC, Yonkers, and Portland/Multnomah County, we assume local taxes are a flat tax on either state taxable income or gross income.

Bonus Tax Strategies
Strategies to manage the taxes you’ll have to pay on a bonus fall into two camps. First, you can reduce your gross income. Second, you can increase the deductions that apply to your income.
1. Make a Retirement Contribution
One of the most effective ways to reduce taxes on a bonus is to reduce your gross income with a contribution to a tax-deferred retirement account. This could be either a 401(k) or an individual retirement account (IRA). The amount you contribute to the retirement account, subject to limitations, reduces your taxable income so you’ll owe less.
The limitations are different for various types of retirement accounts. They also change from year to year. Note that you also can’t get a deduction for contributions to a Roth IRA.
For 2025, the limits are:
- 401(k)s, 403(b)s and most 457s: $23,500 ($31,000 for taxpayers age 50 or older)
- IRAs: $7,000 ($8,000 for taxpayers age 50 or older)
For 2026, the limits are:
- 401(k)s, 403(b)s and most 457s: $24,500 ($32,500 for taxpayers age 50 or older)
- IRAs: $7,500 ($8,500 for taxpayers age 50 or older)
2. Contribute to a Health Savings Account (HSA)
If you’re covered by a high-deductible health plan, you may be eligible to contribute to a health savings account (HSA). These contributions reduce your gross income by the contributed amount. You can also withdraw from an HSA to pay qualified medical expenses without incurring taxes, which makes this one of the most attractive tax-management strategies.
There are limits on how much you can contribute to your HSA. For 2026, the limit is $4,400 for an individual and $8,750 for a family. In 2025, those limits were $4,300 for individuals and $8,550 for families.
3. Defer Compensation
You may be able to save on taxes by asking your employer to delay paying the bonus until January. If the bonus would push your income into a higher tax bracket this year and you expect less income next year, this strategy makes considerable sense. Even if you will still be in the same tax bracket, you benefit by delaying the day you have to pay the taxes by the year.
4. Donate to Charity

If you itemize your deductions rather than taking the standard deduction, you can contribute to a charity to reduce your taxable income. You may want to consider bunching donations by making two years’ worth of planned donations this year. You can donate up to 50% of your adjusted gross income to a qualifying charity, including nonprofits promoting literacy, education and amateur athletics as well as religious charities.
5. Pay Medical Expenses
If you itemize deductions and have medical or dental bills that weren’t reimbursed by insurance, you can reduce your taxable income by using the bonus to pay for them. You can only deduct unreimbursed medical and dental expenses in excess of 7.5% of adjusted gross income.
6. Request a Non-Financial Bonus
You may be able to reduce taxes on your bonus to zero by asking your employer to make it a non-financial bonus. Examples of non-financial bonuses could include the ability to work from home or work flexible hours. Not all non-financial bonuses are tax-free, however. If you get extra paid vacation time instead of a check, for instance, it can be taxed as a financial bonus.
7. Supplemental Pay vs. Regular Pay
If your employer delivers the bonus to you as part of your regular paycheck, regular income tax withholding will apply. If it’s delivered with a separate check, it’s considered supplemental income. The difference is that supplemental income withholding is a flat 22% while ordinary income is withheld at your regular rate.
It might result in more or less withholding to have the bonus delivered as supplemental income rather than as an amount added to your regular check. However, which approach will result in lower withholding depends on your situation.
Bottom Line

Year-end bonuses are subject to taxation like any income received from an employer. Some strategies can help manage or reduce the taxes owed on a year-end bonus, however. Some of these require donating to charity or making a contribution to a retirement or health savings account. Others, such as deferring compensation, will call for some coordination with your employer.
