The move towards the mandatory payrolling of Benefits in Kind (BiKs) has been a significant focus for HM Revenue and Customs (HMRC) in recent years. Following updated interim guidance, HMRC has now confirmed that implementation will take place more gradually than originally anticipated, with a phased approach beginning in April 2027.
From a payroll perspective, this change brings both welcome breathing space and important considerations for employers as they prepare for a fundamentally different reporting landscape.
A more gradual transition
Under the revised timeline, mandatory payrolling will be introduced in two key phases. Initially, from April 2027, only a defined group of benefits will fall within mandatory payrolling requirements. These include:
- company cars and fuel
- vans and van fuel
- private medical benefits
All other Benefits in Kind will, for the time being, continue to be reported via P11D forms or through voluntary payrolling arrangements. The intention is that most of these remaining benefits will then become subject to mandatory payrolling from April 2028, with more complex areas such as beneficial loans and accommodation benefits brought in at a later stage.
This staggered approach reflects HMRC’s recognition of the scale of the change and the practical challenges faced by employers, payroll teams and software providers alike.
What this means in practice
Payrolling Benefits in Kind fundamentally changes how taxable benefits are reported and taxed. Rather than being declared at year end via P11D forms, the taxable value of benefits will be reported in real time through the Full Payment Submission (FPS).
This means that income tax and Class 1A National Insurance Contributions (NICs) can be accounted for during the tax year, bringing benefits reporting much closer in line with standard payroll processes.
For employers, this has the potential to streamline compliance and improve transparency for employees, who will see the tax impact of their benefits reflected more immediately in their pay.
Why the delay matters
The decision to phase in mandatory payrolling follows extensive feedback from stakeholders, including professional bodies such as the Chartered Institute of Payroll Professionals (CIPP). The clear message from the industry was that more time was needed to prepare systems and processes for such a significant shift.
One of the most notable changes relates to the technical requirements of reporting. Under the revised approach, only 32 FPS data fields will initially be required, compared to more than 100 fields that would have been needed to accommodate all benefits in one go. This reduction significantly eases the burden on payroll software providers and reduces the risk associated with implementation.
By scaling back the initial scope, HMRC is aiming to ensure a more stable and manageable transition, helping employers avoid unnecessary disruption.
What about early adopters?
For businesses that have already embraced voluntary payrolling of benefits, the updated guidance provides reassurance. Employers who are currently payrolling a wider range of benefits can continue to do so.
However, from April 2027, only company cars, vans and private medical benefits will need to be reported using the new mandatory FPS data fields. Any additional benefits processed through payroll will continue under voluntary arrangements, and employers should expect that registration requirements will still apply.
This flexibility is helpful for organisations that have already invested in adapting their processes and do not wish to revert to P11D reporting for certain benefits.
Preparing for what’s ahead
Although the phased approach provides additional time, it should not be seen as a reason to delay preparation. Mandatory payrolling represents a fundamental shift in how benefits are handled, and the impact will extend across payroll, HR and finance functions.
Key areas for employers to consider now include reviewing existing benefit offerings, assessing payroll system capability, and ensuring accurate data capture for the benefits that will fall within Phase 1. Clear communication with employees will also be essential, as they will need to understand how and when their tax position may change.
HMRC has indicated that further detailed technical guidance will be issued shortly, which should provide greater clarity on the operational aspects of the new system.
Summary
There is no doubt that the move to mandatory payrolling of benefits is a major change for UK employers. The decision to introduce it in phases is a pragmatic response that should help reduce risk and support a smoother transition.
From our experience, early engagement is key. Even with a revised timeline, the organisations that begin reviewing their processes now will be best placed to adapt with confidence.
