Important Tax Considerations
The 'Bonus' Trap
Many people worry that a bonus will push them into a higher tax bracket and they will net less money. This is impossible. Only the income *above* the bracket threshold is taxed at the higher rate.
Withholding Note
Employers often withhold taxes on bonuses at a flat 22% rate. This might feel like a higher tax, but you will get the difference back as a refund when you file your return.
