At Autumn Budget 2024, the government confirmed that it will go ahead with a simplification measure first announced in January 2024. This new measure will mandate the reporting of Income Tax and Class 1A National Insurance Contributions (NICs) for most benefits in kind (BiKs) in real time from April 2026. This measure is known as mandatory payrolling of BiKs.

Following the announcement in January 2024, the government consulted with a number of stakeholder groups including the Institute of Chartered Accountants in England and Wales (ICAEW) and the Chartered Institute of Tax (CIOT).

Based on the feedback received from stakeholders, a number of changes have been made to the rules for the mandatory payrolling of BiKs.

The main changes are: 

• the delivery of the work to mandate the real time reporting of and payment of tax on BiKs will be phased in from April 2026 – this will mean that all BiKs, with the exception of employment related loans and accommodation, will be mandated to be reported via payroll from April 2026;
• voluntary payrolling will be introduced for employment related loans and accommodation from April 2026. The P11D and P11D(b) process will still be available for those that do not want to payroll these BiKs. The government intends to mandate these BiKs and will set out a timeline in due course;
• an end of year process will be introduced to amend the taxable values of any BiKs that cannot be determined during the tax year. However, it is expected that the taxable values of most BiKs will be reported as accurately as possible during the tax year; and
• HMRC will continue to monitor the penalty position, from April 2026 to April 2027, whilst taxpayers get used to the new process of reporting BiKs. HMRC accepts that there will inevitably be a period of adjustment in the first year.
