No, bonuses are not always taxed at 40%. In the U.S., they are generally treated as "supplemental wages" and are typically subject to a flat federal withholding rate of 22% for bonuses up to $1 million. For amounts exceeding $1 million, the rate is 37%.
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.
Key takeaways
Employers generally withhold taxes on bonuses at a 22% rate, with anything over $1 million withheld at 37%. This is called the percentage method. Alternatively, employers can combine the bonus with your regular pay and withhold tax on the entire sum. This is called the aggregate method.
The tax rate that you will pay on your bonus will depend on the income bracket that you fall into in the 2024/2025 tax year: Basic rate: for earners making between £12,571 to £50,270, your bonus will be taxed at 20%. Higher rate: for those making between £50,271 to £150,000, your bonus is taxed at 40%.
The percentage method is used if your bonus comes in a separate check from your regular paycheck. Your employer withholds a flat 22% (or 37% if over $1 million). This percentage method is also used for other supplemental income such as severance pay, commissions, overtime, etc.
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.
Your bonus was likely taxed at 32% because employers use special IRS rules for "supplemental wages," often applying a higher flat withholding rate (like 22% or sometimes higher if combined with regular pay in the aggregate method) or pushing you into a higher tax bracket temporarily, but you'll get any over-withholding back as a refund at tax time since bonuses are taxed at your actual income tax rate eventually, not a permanent higher one.
The general rule is that employees are taxed at the rate of the marginal tax bracket in which they fall. Let's explain: if their salary is between R 1 and R 216 200, they are in the 18% tax bracket and therefore their bonus will be taxed at 18%.
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.
Keep in mind that a bonus may push you into a higher tax bracket. But, you are subject to a higher rate only on the portion of income that falls into that bracket.
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.
Remember to submit a new W-4 form with your regular withholding allowances after you receive the bonus income. If you fail to change your allowances back, you could have insufficient withholding for the rest of the year. This could result in a hefty tax bill when you file your next tax return.
One of the most notable differences between bonuses and raises is the duration of the compensation. Bonuses are one-time, short-term financial rewards. A raise is an increase to your current salary for the foreseeable future and provides more long-term benefits.
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.
The 40 tax bracket applies to anyone earning over £50,270 annually. This includes employees, self-employed individuals, and those with additional income from rental properties, dividends, or investments.
Section 40(a) of the Income Tax Act specifies certain payments and expenses that are disallowed as deductions when calculating taxable income. These disallowances primarily relate to payments made to non-residents, failure to deduct tax at source (TDS), non-payment of equalisation levy, and specific taxes and cess.
How much does California tax bonuses? California's supplemental wages tax rate is currently 10.23% for bonuses and stock options, and 6.60% for other types of pay.
For example, if your salary is £40,000 and you receive a £5,000 bonus, the bonus pushes you into the higher tax bracket for part of that amount. So, while part of your bonus will be taxed at the 20% basic rate, a portion might also be taxed at 40% depending on your total earnings.
