Bonuses seem to be taxed heavily because the IRS treats them as supplemental income, requiring higher withholding rates (often a flat 22% or higher) through methods like the percentage method, unlike regular pay calculated via your W-4. While this makes your bonus check smaller upfront, it's usually an overestimation, and you get the excess back as a refund when you file your annual tax return, as the bonus is added to your regular income.
In many cases, recipients of bonuses pay a 22% flat federal income tax, along with a 6.2% Social Security tax and 1.45% Medicare tax. Fortunately, you can reduce the tax burden of a bonus by, for example, putting at least some of the money in a 401(k), IRA or health savings account.
Because your bonus increases the total amount for that pay period, it might temporarily move you into a higher tax bracket — meaning more tax is withheld upfront. However, this doesn't necessarily increase your total tax bill for the year; your final tax liability is determined when you file your return.
Key takeaways
The federal bonus tax withholding rate is typically 22%. However, employers could instead combine a bonus with your regular wages as though it's one of your usual paychecks—with your usual tax amount withheld. There are ways to reduce the tax impact of your bonus.
It's possible that a bonus or a pay increase can put you in a higher tax bracket. That means you will pay a higher tax rate on each additional dollar you earn. Some people think they may actually have less after-tax income because of a bonus, but this is not true.
Bonus contributed pre-tax to super
For example, tax on a $50,000 bonus: Paid to you and your marginal tax rate is 32.5% = $16,250. Paid to you and your marginal tax rate is 37% = $18,500.
Yes, it is true you are allowed to change your W-4 to ensure less withholdings on your bonus pay. However, the ramifications of such a change may be unknown until tax filing time. Generally, it is better to leave your W-4 alone and have the extra withholdings.
The benefits of bonus sacrifice
The main benefit of paying your bonus into your pension is tax relief. If you take your bonus as cash, this will be subject to income tax, National Insurance contributions and maybe other deductions (such as student loans).
Impact of a bonus taking your earnings over 100k
Let's say you earn a £100k salary and – good news – you've been awarded a £1,000 bonus. Ready for the bad news? Not only will this bonus be taxed at 40% (leaving you with £600), but you also lose £500 from your tax-free personal allowance.
You can't entirely avoid taxes on a bonus, but you can significantly lower the amount by contributing to tax-advantaged accounts (401(k), IRA, HSA), deferring the bonus to a year you expect to be in a lower tax bracket, or making charitable donations, thereby reducing your taxable income or increasing deductions at tax time.
Why is tax withholding on bonuses so high? Since bonuses are paid in addition to your normal paycheck, taxes are withheld at a higher rate than your regular wages. This is because they are considered supplemental income.
Percentage Method (Most Common) – The IRS requires a flat withholding rate of 22% for bonuses under $1 million (as of 2025). This means your employer will typically withhold 22% of your bonus for federal income taxes—regardless of your actual tax bracket.
Salary Sacrifice of Bonuses and Commissions
A common benefit included in an effective salary sacrifice arrangement is a bonus or commission, when the agreement is established prior to the work that is considered for the period of assessment for the bonus or commission.
Ultimately, the best decision depends on personal income levels, tax brackets, and the company's financial situation. Those in lower tax brackets may benefit from a salary bonus, while high earners typically find dividends to be the more tax-efficient choice.
Tax-Free Vouchers as Bonuses
Up to five small benefits per year, tax-free. The combined value should not exceed €1,500.
Are you wondering how to pay bonuses to employees without taxes? Regretfully, that is not an option. Employers must withhold taxes from employee bonus payments. The IRS mandates different guidelines based on whether you issue stand-alone bonus checks or integrate bonuses into regular wage compensation.
In California, bonuses are classified as supplemental wages and subject to special withholding rules rather than treated as ordinary wages. A flat withholding rate of 10.23% applies to all bonuses in California, regardless of the employee's regular income bracket.
