Employee Benefits and Tax: What UK Payroll Teams Need to Know

Not all employee benefits are taxable in the same way. Some — like pension contributions, cycle-to-work schemes, and childcare vouchers (for legacy users) — are tax-exempt. Others — like company cars, private medical insurance, and interest-free loans above £10,000 — are taxable benefits in kind that must be reported to HMRC.

There are two ways to handle taxable benefits: through the P11D process (reporting at year-end) or by payrolling the benefit (including its taxable value in the monthly payslip). HMRC encourages payrolling because it spreads the tax liability across the year and removes the year-end P11D burden. Employers who payroll benefits must register with HMRC before the start of the tax year.

Mellow's payroll engine supports payrolled benefits. You add a benefit record to an employee's profile — car allowance, private medical, gym membership — and Mellow adds the taxable value to the gross pay calculation each period. The PAYE is deducted correctly, the payslip shows the benefit clearly, and there is no P11D to file for those benefits at year-end. Less admin, more transparency for the employee.
