Payrolling Benefits in Kind: What Employers Must Do by 2027

Employers that leave preparations for benefits in kind until the end of the tax year could face a major payroll headache from April 2027. Company cars, car fuel, vans, van fuel and employer-provided medical benefits will need to be reported through payroll in real time, meaning payroll teams must have accurate benefit information ready for each relevant pay run rather than relying on year-end reporting. 

According to HMRC, the change is expected to affect approximately 4 million employees and 300,000 employers, highlighting the scale of the transition. With benefit calculations, payroll software and internal reporting processes all needing attention, what should employers have in place before 6th of April 2027? 

Why is HMRC Making Payrolling Benefits Mandatory?

Payrolling means putting the taxable value of a benefit through the pay run, so tax is collected in the same period. It has been voluntary since 2016. What changes is the choice. From 6 April 2027, payrolling benefits in kind becomes the default for a named group of benefits.

Making payrolling benefits mandatory closes the gap between a benefit being given and the tax on it being paid. Income Tax and Class 1A National Insurance run through the Full Payment Submission you already file, which cuts the year-end P11D work. The HMRC payrolling benefits timetable has moved twice, so check the current position on GOV.UK before fixing internal deadlines.

Employers who treat the payrolling process as a software question usually find the harder work sits in HR, fleet and finance data. Review that flow early, and ask your provider the same questions if you are outsourcing payroll. The same benefit figures feed the year-end position, so it helps if the team preparing your annual accounts sees the data in the same shape.

What Should Employers Do Before April 2027?

There is a clear sequence here, and the early steps make the later ones cheaper. Anyone running payroll services in house should work through them in order.

1. Sort the benefits: Split every benefit into three groups, April 2027, April 2028, and outside the mandate. This single exercise drives every other decision in the payrolling process.
2. Ask about the software date: The payroll software provider, or the firm running your payroll outsourcing services, should be able to say when HMRC functionality for payrolling of benefits will land and what updates software developers still need to make in the payroll system. HMRC has been finalising technical specifications with developers through the second half of 2026, so a date should be available.
3. Check the registration position: There is nothing to register for benefits that fall inside the mandatory regime, because real-time reporting becomes automatic. Employers who expected to register for payrolling benefits as a rehearsal in 2026-27 have missed that route, which closed on 5 April 2026.
4. Decide on loans and living accommodation: A separate window to register for payrolling benefits of that type is expected to open in November 2026 and close on 5 April 2027. Those benefits stay on a voluntary basis and sit outside the first mandatory phase.
5. Model cash flow for 2027-28: Monthly Class 1A on 2027-28 benefits runs alongside the 2026-27 Class 1A still falling due by 22 July 2027.
6. Build an estimate and correction routine: HMRC allows a reasonable estimate where a value is not known during the year, using the cash equivalent figure at the time, with a correction window closing on 22 July after the tax year ends so it can be replaced with the exact value if needed.
7. Brief employees before the first run: Payslips change shape and take-home pay falls, so the explanation needs to arrive first. Employers must tell staff about payrolled benefits by 1 June, and employees pay tax through payroll, which means employees pay is affected sooner.
8. Name an owner: Payroll, HR and finance need one person between them who signs off the figures each month.
9. Review capacity honestly: Employers without the internal resource to carry monthly benefit reporting often turn to outsourcing payroll services at this point rather than recruit for it. Comparing the in-house cost against payroll outsourcing services before the 2027 budget is set makes that call easier, especially as a professional provider saves significant administrative time and automated systems reduce manual-entry mistakes.

None of this needs to happen at once. Steps one to three can be done this quarter with the information already in the business, and the rest follows once the software date is confirmed. The employers who start early tend to spend the least on it.

Which Benefits Move and Which Wait Until 2028?

The phasing is the part employers get wrong, because making payrolling benefits mandatory happens in two stages rather than one, and a mixed benefit set splits across both.

Phase	Benefits covered	How it is reported
From 6 April 2027	Company cars, car fuel, vans, van fuel, and employer-provided medical and dental cover	Income Tax and Class 1A in real time through the Full Payment Submission
From 6 April 2028	The remaining benefits, including gym memberships, non-cash vouchers and mobile phones outside the exemption	Same real-time treatment as Phase 1
Outside the mandate	Interest-free and low-interest loans, and employer-provided living accommodation	P11D, or under arrangements an employer can voluntarily payroll if it registers

A benefit set that splits across both dates needs one plan, not two. Map your employee benefits to each phase now and you know which data feeds have to be ready for April 2027 and which other benefits can wait until 2028, all under one set of controls. Some transitional exceptions have applied for a longer period in previous years, so employers should still map each benefit against current HMRC dates rather than assumptions.

What Should Payroll Teams Check as the Rules Bed In?

Points worth watching as the HMRC payrolling benefits rules bed in:

• The P11D does not disappear. It is still needed for 2026-27, for anything outside scope during 2027-28, and afterwards for loans and accommodation that have not been payrolled voluntarily; P11D(b) also remains relevant for reporting Class 1A National Insurance Contributions and the related National Insurance Contributions position on benefits reported.
• Tax deducted on payrolled benefits cannot exceed 50% of cash pay for the period, which can bite where a modest salary carries a high-value company car, or when low cash pay such as statutory sick pay makes the cap more noticeable.
• HMRC has confirmed it will remove payrolled benefits from tax codes before 6 April 2027, and employees’ tax codes should stay current through Real Time Information submissions, though codes still deserve a check either side of the switch.
• Penalties are expected to be light touch through 2027-28 where errors are not deliberate, with the full regime applying from 2028-29.
• An employer who wants to register for payrolling benefits covering loans or accommodation gets one window, and missing it means another year of P11D reporting for those items.
• Even where a benefit is processed through payroll, the correct amount still needs to be added to taxable pay so the employee’s taxable pay and tax deductions stay accurate for each taxable benefit.
• Employers must tell staff about payrolled benefits by June 1 and should explain how the taxable benefit will appear in payroll records.

Running both phases through a single payrolling process keeps controls in one place. Where internal resource is thin, payroll outsourcing absorbs the phasing without adding headcount and hands the software timetable to a provider, rather than an annual scramble.

Get Ahead of the April 2027 Switch

The one thing to do now is the sorting exercise. List every benefit against its phase, with the supplier or internal owner who holds the value for it, and you have a map of which data feeds need fixing and by when. It takes little more than an afternoon, and it turns the software question, the budget and the employee briefing into three manageable tasks instead of one large unknown.

Frequently Asked Questions About Payrolling Benefits

Can Wilds run our payrolling process for us before April 2027?

Starting before the mandate arrives is easier than moving mid-year. Taking over the payrolling process means reviewing your benefit list, agreeing where the employer works out each taxable value before handover, setting up the software, and moving the process into a managed service with a parallel period against your existing output. Employers who hand this over during 2026 have time to fix data gaps in HR and fleet records before the first live run. 

The work sits alongside year-end accounts and compliance rather than separately from it. Nothing needs to change in the same month as your year end. For a handover timed around your own pay dates, our payroll specialists can map the steps, act as an extension of the HR team, provide expert support during setup and handover, and agree a start date.

Can we outsource payroll for directors’ benefits only?

Directors’ benefits sit inside the same payroll as everyone else’s, so they cannot be split into a separate service. What can be arranged is a closer review of the director package, covering cars, medical cover, loans and accommodation, alongside a standard payroll service for the company. Close company rules and the interaction with dividends and the self assessment return make this worth looking at separately from the pay run itself. 

The reporting treatment for loans and accommodation also differs from the rest of the package, which affects what lands in the pay run. If the director package is your main concern, our tax planning specialists can review it alongside the payroll work.

How long does it take to move payroll to an outsourced provider?

Allow six to eight weeks for a straightforward move, longer where benefit data is scattered or the current provider is slow releasing records. The steps are gathering data, handling any benefit-related complex calculations, setting up the payroll, agreeing approval routines, and running one cycle in parallel. 

Moving at the start of a tax year or a quarter reduces the reconciliation work. Leaving it until spring 2027 means changing provider and adopting real-time benefit reporting in the same run, which is avoidable. Agree in writing who runs the final pay period under the old arrangement. For a start date that fits around your year end, our payroll team can set the timetable with you so it can adapt as your business grows.

Is outsourcing payroll services worth it if we only have two or three benefits?

Often yes, because workload follows the reporting rhythm rather than the number of benefits. Two benefits still need monthly values, correct cash equivalents to work out the employee’s taxable pay and the correct amount of tax each pay period, a data feed, and a check that the tax code has been adjusted. Doing that in house means someone learning the rules for a handful of entries. 

Outsourcing payroll services spreads that cost across a provider who runs it many times a month, and many employers use one because even a small benefit set still creates recurring payroll reporting and pay tax obligations. Smaller employers also carry more risk from a single absence in the finance team. The cost of one missed deadline often covers a year of fees. If your benefit set is small, our payroll team can tell you honestly where the line falls for a business like yours.
