What is payrolling benefits in kind and how does it work?

Full answer

Payrolling benefits in kind (BIK) is the system where an employer accounts for the tax on workplace perks - company cars, fuel, private medical cover, gym memberships and similar - directly through payroll each pay period, rather than reporting them separately on a P11D after the tax year ends. The cash-equivalent value of the benefit is added to your taxable pay, so Income Tax is collected as you earn rather than clawed back later through a reduced tax code. Who it affects: any employee receiving non-cash benefits whose employer has registered to payroll those benefits with HMRC before the start of the tax year. From April 2026, HMRC is moving toward mandatory payrolling of most BIKs (with some exceptions such as beneficial loans and accommodation, which can still be handled differently), so far more employees will see benefits taxed in real time. Mechanism and example: suppose a benefit has a cash-equivalent value of GBP 1,200 a year. Payrolled, GBP 100 is added to your taxable pay each month. A basic-rate (20%) taxpayer pays GBP 20 a month (GBP 240 a year) in extra Income Tax; a higher-rate (40%) taxpayer pays GBP 40 a month (GBP 480 a year). Note that Class 1A National Insurance on most benefits is still settled by the employer, not deducted from you. The advantage is accuracy: you avoid a large tax-code adjustment or an unexpected underpayment a year later. The downside is a slightly lower monthly net pay. Your payslip should show the benefit value separately so you can check it. To see how an added taxable amount changes your monthly net pay, use a take-home pay or income tax calculator and add the benefit value to your gross.
