Tax rules can vary by country, but generally, Christmas bonuses are considered taxable income. This means that the value of your bonus is subject to income taxes and may also be subject to other deductions like social security taxes or Medicare taxes. The exact amount of taxes you owe will depend on your individual circumstances, such as your income level and any deductions or credits that you may be eligible for. If you have any questions about your taxes, you should consult with a qualified tax professional.
