When you get a K code
GOV.UK gives these examples: paying tax you owe from a previous year through your wages, getting the State Pension or taxable state benefits, company benefits such as a company car, or more savings interest than your Personal Savings Allowance. An employer cannot take more than half of your pre-tax pay under a K code. Read GOV.UK's guide.
