Mandatory payrolling of benefits in kind and expenses – interim guidance and legislation

Annex 3 – additional benefits in kind fields likely to be required on Full Payment Submission returns

Information about the additional benefits in kind (BiKs) fields likely to be required on Full Payment Submission (FPS) returns.

Information about the additional benefits in kind (BiKs) fields likely to be required on Full Payment Submission (FPS) returns from April 2027.

The potential fields in this chapter represent some information that is currently collected on the P11D and P11D(b) forms. We are investigating enhancements to the Class 1A Adjustment fields for phase 1 benefits and, subject to engagement with stakeholders, we may introduce a small number of data items to ensure all relevant information is captured consistently and accurately, though these data items will reflect the information for phase 1 benefits. This will be confirmed once technical specifications are produced in autumn 2026. 

Employers will only be required to complete the relevant field in relation to the benefits they have provided to their employees. For example, if no private medical insurance has been provided, employers will not be required to add any data to that section of the Full Payment Submission (FPS).
