Tax Code K475 Explained
Your tax deductions (such as taxable benefits or unpaid tax) exceed your Personal Allowance. Instead of receiving a tax-free amount, £4,759 is added to your taxable income. This means you are taxed as if you earn £4,759 more than your actual pay. Common reasons include a company car, private medical insurance, or tax owed from a previous year. The maximum tax deducted through a K code cannot exceed 50% of your gross pay.
