A $ 100 , 000 $ 1 0 0 , 0 0 0 bonus is generally taxed as supplemental income, with a mandatory 22% federal income tax withholding (up to $ 1 $ 1 million).

Bonuses under $1 million are typically taxed at a flat rate of 22%. Example: If you receive a bonus of $20,000, the flat federal tax rate of 22% would amount to $4,400. If you receive a bonus above $1 million, you'd pay the 22% rate on the first million. Beyond that, the rate jumps to 37%.
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.
That means that your net pay will be £65,960 per year, or £5,497 per month. Your average tax rate is 34.0% and your marginal tax rate is 43.3%.
Percentage method for bonuses
If you receive a bonus separately from your regular paycheck, your employer is probably using the percentage method to calculate how much tax to withhold on your bonus. Here's how that works: The employer withholds 22% of your bonus for taxes if your bonus is under $1 million.
You can choose not to pay 40% income tax on all of your earnings by: Keep some of your income within the tax-free personal allowance (currently £12,570), so you don't pay any income tax on that portion of your earnings.
How can you lower taxes on bonuses?
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.
For a single filer earning $100,000 in California, the total tax burden is approximately: Federal Tax: $13,614. California State Tax: $5,842.
For a higher rate taxpayer, a £10,000 bonus will instantly be whittled down to £6,000 by income tax. National insurance at 2% would take a further £200, leaving you with just £5,800 of your £10,000 bonus. However, there is a way to (legally) reduce the tax you pay on your bonus, and that's with bonus sacrifice.
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.
The bonus tax rate is the same as the individual tax rate.
Bonuses are usually taxed on both the federal and state levels, which means you have to report and pay taxes on your bonuses twice. However, supplemental income tax rules and rates can vary depending on the state you're in.
The lottery agency immediately withholds 24% of lottery winnings over $5,000, which can lower what you owe the IRS come tax time. For example, on a $100,000 lottery win, the agency withholds $24,000 for federal taxes, leaving you with a take-home amount of $76,000.
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.
The IRS considers bonuses to be supplemental income and taxes them at a flat withholding rate of 22% (a higher rate applies to bonuses over $1 million).
