Rather than report benefits on a P11D at the end of the year, you can instead use Payrolling of Benefits in Kind (PBIK).
You must have registered with HMRC to do this before the start of the tax year.
When approving an employee expense
Go to HR
Select Expenses
Select the expense and benefit to approve by clicking on Accept
Click on the dropdown menu
Select PAYE
Manually from an employee profile
Go to My employees
Select your employee by clicking on View
Scroll down to Benefits
Click on Add new benefit
Select the tax year
Provide a title to identify the expense or benefit easily
Select the type of benefit
Select NEXT
An additional line will appear on the on-screen payslip showing the value of the Benefit. Tax will be calculated on pay as usual, adding the value of the Benefit.
Whilst the Benefit increases the taxable pay, it doesn't add anything to the employee's take-home pay and isn't visible on the payslip PDF.
