The Company assets tab is where you record vehicles owned by your business, such as cars or vans used by your team. These are treated as benefits in kind for the employees who use them.
Adding a vehicle
Add a company car or van and enter its details, including the tax information for the vehicle. Once saved, you can assign it to one or more employees as a benefit in kind from the employee profile.
How benefits in kind are reported
A benefit in kind is something of value you give an employee on top of their salary, such as a company car. You report it to HMRC in one of two ways: by payrolling it, which means taxing its cash equivalent through payroll during the year, or on a P11D after the tax year ends. Either way you also submit a P11D(b), which declares the total employer Class 1A National Insurance due. In Moonworkers these are carried by the EXB, or Expenses and Benefits, online submission.
Class 1A National Insurance
Company cars, vans and fuel are Class 1A benefits. Class 1A is employer-only National Insurance on benefits in kind, charged at 15% for the 2026 to 2027 tax year. You report P11D and P11D(b) by 6 July after the end of the tax year, and pay the Class 1A due by 22 July, or 19 July if you pay by cheque.
A change to prepare for
From April 2027, payrolling of most benefits in kind becomes mandatory and will be reported in real time through the FPS. It is being introduced in phases, so it is worth preparing now.
