The flat tax rate is 22% for most bonuses. If your income falls into the top tax bracket, your bonus may be calculated at a flat rate of 37%. Bonuses are also subject to Medicare and Social Security taxes. These taxes apply in addition to any applicable federal, state, and local taxes.
National Insurance contributions (NICs) are also payable on bonuses. For example, if you earn £40,000 annually and receive a £4,000 bonus, it could be taxed at 20% (basic rate) and 8% for NICs, leaving you with significantly less in take-home pay.
Key takeaways
— your employer must withhold some of the money to send to the IRS for taxes. Your employer may withhold 22 percent of your bonus for taxes (37 percent for any bonus amount above $1 million), or your employer may withhold taxes at the same rate as they do for your paycheck.

One of the simplest ways to 'sacrifice' your bonus is to ask your employer to pay the amount into your workplace pension. This method can also help to mitigate the 60% tax trap, as well as preserving or restoring entitlement to Child Benefit Allowance.

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%.
In California, bonuses are taxed differently from regular income. They are considered supplemental income and are subject to both federal and state taxes. California uses a flat rate for state tax on bonuses, distinct from regular income tax rates.
IRS Methods for Taxing Bonuses
Under the percentage method, the IRS requires a 22% withholding of the bonus for federal income tax. For example, with a $10,000 bonus, $2,200 is set aside for federal income tax, leaving the employee with $7,800.
The bonus tax rate is the same as the individual tax rate.
The IRS allows two primary methods for taxing bonuses. The percentage method uses a flat 22% federal tax rate. This method is straightforward but could result in over-withholding for some individuals. The aggregate method combines your bonus with your regular earnings and then calculates taxes based on the total.
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.
On a £5,000 salary, your take home pay will be £5,000 after tax and National Insurance. This equates to £416.67 per month and £96.15 per week. If you work 5 days per week, this is £19.23 per day, or £2.40 per hour at 40 hours per week.

Not only will this bonus be taxed at 40% (leaving you with £600), but you also lose £500 from your tax-free personal allowance. To add insult to financial injury, that £500 will also be taxed at 40%, costing you another £200.
The percentage method
The IRS specifies a flat “supplemental rate” of 22%, meaning that any supplemental wages (including bonuses) should be taxed in that amount. If you receive a $5,000 bonus, under this rule, $1,100 (22% of $5,000) goes straight to the IRS.
Before you start making plans to spend it, it's important to understand how that income will get taxed. Yes, your bonus money is taxable—typically 22% is withheld for taxes—and it's up to you to make sure the appropriate amount gets paid.
Suppose an employee is receiving a $10,000 bonus. Using the flat-rate method, the IRS requires you to withhold a fixed 22% federal tax on the bonus, no matter the employee's regular paycheck or tax bracket. So, the bonus is $10,000, and based on the fixed rate, the federal withholding would be $10,000 x 22% = $2,200.
