HRMC have published interim guidance and legislation for mandatory payrolling of taxable expenses and benefits in kind from April 2027. This is a helpful consolidation of other guidance that is available on Gov.UK and includes worked examples to help employers and software developers prepare for the changes.

The consolidated guidance contains many sections and, as such, is a considered read. 

The most important thing to realise is that this will happen in April 2027 and members need to be getting ready. This will mean talking to clients and ensuring they are prepared. With all the guidance and legislation in the world, successful payrolling can only work if payroll is advised of the taxable expense and benefit information in real time.

We detail the sections in the consolidated guidance:

Title

Contents

Introduction

An introduction to the draft guidance and legislation.

Who should read this

Basically, anyone that is involved with taxable expenses and benefits in kind.  Perhaps, the guidance could have referred to the vital role that bookkeepers, agents and accountants will play and how the move is likely to impact this population the most

The default operation of mandatory payrolling

Essentially, the real time taxation of expenses and benefits plus the calculation of Class 1A National Insurance

Reporting requirements

As we know, the P11D is going apart from employer-provided accommodation and beneficial loans.  So the only route will be to declare the taxable expenses and benefits in real time via the Full Payment Submission (FPS)

Getting ready for mandatory payrolling of benefits in kind

Probably, the most important section.  HRC’s guidance says that their points need to be considered ‘at least a year before the April 2027 introduction’.  ICB agrees

How to report a benefit in kind in real time

A long section which can be summarised – ‘you need to put the taxable value through the payroll and declare it on the FPS

What happens when the full amount of tax cannot be collected either within a pay period or tax year

This is a section that will need to be expanded as there will be justifiable reason why expenses and benefits cannot be processed in real time.  Possibly, we are not aware of them at all.  There was talk about an ‘end of year’ process whereby the taxable value could be declared outside the normal payroll frequency

Reporting Class 1A National Insurance contributions

A message for clients is that Class 1A National Insurance will be accrued in real-time and payable with the monthly PAYE remittance.  The liability is moving from an annual one to a monthly one

Dealing with employees who leave during the tax year

This section talks about a ‘BiKs update process’ i.e. updating HMRC’s systems via an additional FPS where expenses and benefits cannot be payrolled.  However, it is under this section that deals with leavers so, perhaps, the ‘P11D by payroll’ option is no longer going to be available for errors and only for employees who leave in the year

Penalties and interest

For 2027/28, the first year of operation, there will not be penalties for failing to process in real time.  They will apply from 2028/29

Moving employees from one payroll to another

This section refers to Gov.UK guidance and contains nothing new.  However, it is a reality that employees move from one payroll to another, probably due to a PAYE scheme mergers, successions or transfers

Payment reference numbers, P60s and P45s

Perhaps one of the last sections to be read as there is no new information here

Future updates and timeline of delivery

A long timeline of how this will progress in terms of the legislation and further guidance.  ICB notes the voluntary PBiKs registration service will close on 05 April 2026.  Hopefully, this will be after 10pm on this day as this is the deadline for registering to voluntarily payroll for tax year 2026/27

What to do if you have questions or concerns

This says that HMRC will work with employers and stakeholders ahead of mandation.  A contact E-Mail is address is quoted and HMRC will ‘consider’ the comments made but will not reply to them!

Annex 1 – payrolling examples for different scenarios

This gives examples of SOME benefits, probably not the ones that are most common.  It does go into a lot of detail about payrolling the benefit for ‘classic cars’ (not common) and accommodation and beneficial loans (which are not being mandated from 2027)

Annex 2 – draft legislation

This section details when legislation will be in place

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

For software developers largely.  But, of note is that fact that all fields on the P11D will now be included in payroll software for reporting via the FPS.  Depending on the taxable expenses and benefits the client has, this is massive additional reporting.  Basically, if it was reported on the P11D it will have to be reported via payroll from April 2027

 

For Bookkeepers

ICB welcomes this consolidated guidance.  Our advice to members is to regard the move to payrolling as a massive transition project if, indeed, you have clients that will be impacted. 

Don’t forget that the abolition of the P11D does not mean benefit in kind knowledge is abolished as well.  Simply, this knowledge will be required 52 weeks of the year, each time the payroll is processed.  This is important if members have an income stream from the production of P11Ds.
