Changes to reporting of BiKs

Mandatory payrolling of benefits in kind (BiKs) and taxable employment expenses will be introduced from 6 April 2027. This represents a major change in reporting and means that for most benefits, the annual P11D form will no longer be required from the start of the 2027-28 tax year.

The requirement to report Income Tax and Class 1A National Insurance on most BiKs through Real Time Information (RTI) was originally due to start on 6 April 2026 but has been delayed until 6 April 2027 to allow additional time for employers, payroll professionals, software providers and agents to prepare.

The deadline to register for the current voluntary payrolling service for the 2026-27 tax year is 5 April 2026. After this, the service will close in preparation for the introduction of mandatory payrolling. 

From April 2027, employers will report BiKs and expenses via the Full Payment Submission (FPS), aligning reporting with the process currently used for reporting salaries. The number of RTI fields will be expanded to reflect the data currently captured through P11D and P11D(b) forms. Employers will also have the option to payroll employment-related loans and accommodation on a voluntary basis.

To support implementation, HMRC will waive penalties for inaccuracies related to mandatory payrolling for 2027-28, provided there is no evidence of deliberate non-compliance. However, existing late filing, late payment penalties and interest will continue to apply.

HMRC has confirmed that its Basic PAYE Tools software will also be updated to support payrolling of benefits in kind from April 2027.
