If you run payroll for a UK business, you’ve probably heard whispers about a big change coming to how benefits in kind get taxed. The short version: mandatory payrolling of benefits in kind is HMRC’s plan to move benefit reporting from once-a-year P11D forms to real-time payroll reporting, and it’s arriving in phases starting April 2027. This isn’t a small tweak. It touches payroll software, HR processes, employee payslips, and how your finance team plans for tax throughout the year.
Here’s the good news. HMRC pushed back and softened the original timeline after employer feedback, so you’ve got more breathing room than first announced <cite index=”6-1″>the introduction of mandatory payrolling of benefits in kind has been delayed until 6 April 2027, having originally been planned for April 2026</cite>. Even better, the rollout isn’t all-or-nothing. This guide walks through what’s changing, when, who it affects, and exactly what to do before the deadline hits.
What Does Payrolling Benefits Actually Mean?
Benefits in kind (BiKs) are perks you give employees that aren’t cash, think company cars, private medical cover, or gym memberships. Right now, most employers report these once a year using a P11D form, and tax gets sorted out after the fact.
Payrolling changes that. Instead of waiting until year-end, you calculate the taxable value of the benefit and spread it across each pay period <cite index=”6-1″>the employer works out what the yearly value of the benefit is, divides this by the number of pay periods in the year and this amount is taxed each period</cite>. Employees pay tax on their benefits gradually, the same way they pay tax on salary. No surprise bill in October. No confusing tax code adjustment months later.
Why Is HMRC Making This Mandatory?
HMRC wants tax collected accurately and in real time, not reconciled months after the fact. Payrolling cuts down on year-end paperwork, reduces incorrect tax codes, and lines up benefit reporting with the same Real Time Information system already used for salaries. Fewer manual corrections means fewer errors on both sides.
When Do the Changes Actually Take Effect?
This is where a lot of employers get confused, so here’s the plain version.
| Phase | Date | What’s Included |
| Phase 1 | 6 April 2027 | Company cars, car fuel, vans, van fuel, employer-provided medical benefits |
| Phase 2 | 6 April 2028 | Most other taxable benefits |
| Ongoing | No fixed date yet | Employment-related loans and living accommodation (voluntary only, for now) |
HMRC confirmed this phased approach after industry pushback on the original all-at-once plan <cite index=”3-1″>under previous proposals, employers were expected to pay almost all Benefits in Kind from April 2027.However, following delays in publishing detailed technical guidance, HMRC has now confirmed a more gradual rollout</cite>. If you want to voluntarily pay payroll benefits outside Phase 1 for the 2027/28 tax year, you’ll need to register with HMRC by 5 April 2026.

Who Does This Actually Affect?
Pretty much everyone touches payroll or benefits in your business, honestly. Payroll teams are the ones facing the biggest shift: new software requirements, new calculation processes, and a lot more happening every pay period instead of just at year-end. HR carries a different weight: keeping benefit records accurate and current becomes non-negotiable once that data feeds straight into real-time reporting.
Finance shouldn’t ignore this either. Cash flow and NIC timing both shift under the new system, and that’s worth modelling ahead of time rather than discovering it mid-year. Directors, as always, hold ultimate responsibility if compliance slips. And employees? They’ll notice the change most directly benefit values start showing up on regular payslips instead of arriving as a mysterious year-end letter nobody quite understands.
What Actually Changes?(P11D vs Payrolling)
| Factor | Current System (P11D) | New System (Payrolling) |
| Reporting | Annual, after tax year ends | Real-time, each pay period |
| Tax collection | Adjusted via tax code, often months later | Deducted as you go |
| Employee visibility | One annual summary | Reflected on every payslip |
| Employer admin | Concentrated at year-end | Spread across the year |
| Error correction | Fixed retrospectively | Requires in-year adjustments |
Where Employers Usually Trip Up?
A lot of businesses wait until 2027 rolls around to actually start preparing, and that’s usually a mistake. Payroll software updates take time. So does staff training, and so does proper testing. Starting during the 2026/27 tax year gives you breathing room to catch problems while they’re still cheap to fix.
There’s also a quiet assumption that trips people up: that an outsourced payroll provider will just handle everything automatically. They’ll manage the mechanics, sure, but the accuracy of your benefit data and the job of explaining changes to employees still sits with you.
And don’t underestimate how many questions land on HR’s desk once payslips start showing new deductions. People notice changes to their pay before they read any explanation you’ve sent them, so a short internal FAQ ready before rollout saves a lot of repeated back-and-forth later.
Clearing Up a Few Misconceptions
There’s a persistent myth going around that this means employees end up paying more tax. They don’t say the amount owed stays exactly the same, only the timing changes. Instead of one lump adjustment months later, it’s spread evenly across the year, which honestly tends to be less of a shock for most people.
Another one worth killing off: the idea that small businesses get a pass. There’s no confirmed exemption for smaller employers right now, so if you’re providing relevant benefits, you’re in scope regardless of headcount.
And no, P11Ds aren’t vanishing overnight in 2027. They’ll still be needed for anything outside Phase 1, plus loans and accommodation, until HMRC confirms otherwise.
Getting Ready, Practically Speaking
If you want a quick working list to hand your team, here’s what actually matters:
- Audit every taxable benefit currently provided
- Confirm your payroll software supports real-time benefit reporting
- Register with HMRC by 5 April 2026 if voluntarily payrolling early
- Brief HR and finance teams on new responsibilities
- Draft employee-facing communications well before rollout
- Test payroll calculations before go-live
Frequently Asked Questions
Do I need to change anything before April 2027 if none of my benefits fall into Phase 1?
Not urgently, but it’s worth checking now rather than later. If you provide benefits outside company cars, fuel, vans, or medical cover, you’ve got until April 2028 before mandatory payrolling applies to you. That said, if you’d rather get ahead of it and pay payroll voluntarily from 2027/28, you’ll need to register with HMRC by 5 April 2026 miss that window and you’re stuck reporting via P11D for another year.
Will this change how much National Insurance my business pays?
The total amount owed shouldn’t change, but the timing will. Class 1A NIC gets collected through payroll in real time rather than as a single year-end payment, which affects cash flow planning more than it affects the actual liability. Worth flagging to your finance team early, since spreading a cost across twelve months feels different than budgeting for one lump sum.
What happens if my payroll software isn’t ready in time?
That’s genuinely one of the biggest risks employers face right now, since software vendors are still rolling out updates to support real-time benefit reporting. If your provider hasn’t confirmed readiness, ask directly and get a timeline in writing. Waiting until early 2027 to find out your system can’t handle it leaves almost no room to fix things before the deadline.
Can I payroll some benefits and still use P11D for others?
Yes, and for most employers this will actually be the reality during the transition. Phase 1 benefits (cars, fuel, vans, medical cover) move to payrolling from April 2027, while everything else stays on P11D until Phase 2 in April 2028. It’s a hybrid period, which is exactly why keeping clear records of what’s reported matters so much right now.
Does mandatory payrolling apply to loans and accommodation benefits too?
Not yet, and there’s no confirmed date for when it will. HMRC has kept these two categories out of the mandatory rollout for now, though employers can choose to pay them voluntarily if they register to do so. A firm timeline for bringing them into the mandatory system hasn’t been published worth checking HMRC’s updates periodically rather than assuming the current exemption is permanent.
