How to calculate Class 1A Nic on aa P11D(b) when benefit is payrolled ?

SUGGESTED

Hello. We currently use sage payroll for payroll and sage P11D for benefit in kind for our employees. For the tax year 24.25 we payrolled all medical insurance benefits for employees. This means that only employees with a company car require the production of a P11D. We will payroll the company car benefit from 25.26. My question is how using Sage P11D can we capture the calculation of the Class 1a NIC for the employees with payrolled medical benefit, without producing a P11D ? Thanks in advance.
