Payrolling Benefits: 7 Steps UK Employers Must Take by 6 April 2027
Payrolling benefits moves the tax on things like company cars, fuel and medical cover into real-time payroll instead of a year-end P11D form. It’s already optional and genuinely useful, but from 6 April 2027 it becomes mandatory in phases, starting with benefits that make up roughly 92% of current P11D value. The trade-off is simple: less year-end paperwork, but earlier tax and National Insurance cashflows. Employers should register now, audit which benefits they provide, and start testing payroll software.
TL;DR:
Payrolling benefits shifts benefit reporting into payroll, starting with 92% of current P11D value from April 2027, with full coverage by April 2028.
Employers must register, audit benefits, and test payroll systems early to handle increased data and earlier NIC payments without errors.
Only company cars, fuel, vans, and medical insurance are included in Phase 1, while accommodation and loans will remain outside mandatory payrolling.
Employees will see benefits taxed earlier through payroll, and employers must manage in-year NIC payments, which could impact cashflow planning.
Employers need to avoid deducting more than 50% of an employee’s pay for benefits in a period, as exceeding this limit requires fallback on P11D reporting.

What payrolling benefits actually changes for employers
Payrolling shifts benefit-in-kind reporting away from the annual P11D form and into your regular payroll runs, using the same Real Time Information (RTI) submissions you already send HMRC for salaries. Instead of totting up a company car’s taxable value in July for the previous tax year, you add its cash equivalent to taxable pay each period and deduct tax as you go through the Full Payment Submission. Employees see the tax spread across twelve pay periods rather than facing a lump adjustment to their tax code months later.
For HR and payroll teams, that’s a meaningful shift in workload, not just timing.
The advantages are real:
Fewer P11Ds to complete each July, since payrolled benefits drop out of that process entirely
Tax codes stay cleaner because HMRC doesn’t need to estimate benefit values and adjust codes retrospectively
Employees get more accurate, more current deductions instead of a surprise bill or restricted code the following year
Year-end admin shrinks, freeing payroll teams from the annual scramble to value cars, fuel and medical benefits
The drawbacks are just as real:
Employees pay tax on benefits sooner, which can catch people out if they haven’t budgeted for it
Employers must calculate and pay Class 1A National Insurance contributions in-year rather than as one annual sum, which changes cashflow planning
Payroll teams need reliable, timely data from benefit providers (leasing companies, private medical insurers) every single period, not just once a year
None of this is difficult in isolation. It’s the combination of earlier deadlines and more frequent data handling that catches unprepared businesses out.
Which benefits can be payrolled, and the 2027 timetable
Not every benefit qualifies, and the rules matter because getting this wrong means an incorrect payroll deduction and a messy correction later.
Benefits that can be payrolled today (and form Phase 1 from April 2027):
Company cars
Car fuel
Vans
Van fuel
Employer-provided medical or dental insurance
Benefits that stay outside the mandatory scope, even after the rollout completes:
Employer-provided living accommodation
Beneficial or low-interest loans
HMRC’s own guidance confirms both the mechanics of adding cash equivalents to payroll and the exclusion of accommodation and loans from mandatory treatment, at least for now.
Key figure: Phase 1, starting 6 April 2027, covers benefits representing around 92% of P11D value currently reported across UK payrolls. Full mandatory coverage of the remaining benefit types follows by April 2028.
That 92% figure tells you where to focus. If your business provides company cars or medical cover, you’re in the first wave whether you’re ready or not. The gap between Phase 1 and full rollout in 2028 also creates a transitional overlap risk: employers may find themselves settling 2026/27 Class 1A NICs under the old P11D timetable while simultaneously starting in-year NICs payments for 2027/28.
Getting payroll ready: a step-by-step checklist
Preparation for mandatory payrolling isn’t a single project you tackle in March 2027. It’s a sequence of smaller tasks best spread across the year before, and advisers consistently point to the same set of priorities when helping employers prepare.
Register with HMRC’s payrolling service. If you haven’t already, use the online payrolling service to register the benefits you provide and confirm your status ahead of the tax year they apply to.
Audit every benefit you currently provide. Tag which ones fall into Phase 1 (cars, fuel, vans, medical) and list exactly which employees are affected. If you provide company cars, this is where most of your risk sits.
Update and test your payroll software. Confirm it maps benefit values correctly into FPS fields, and run a test cycle with real employee data before going live.
Arrange reliable data feeds from benefit providers. Leasing companies and insurers need to supply values on a schedule that matches your pay periods, not once a year.
Decide how you’ll estimate cash equivalents and reconcile true-ups. HMRC allows some year-end adjustment, but you shouldn’t treat reconciliation as your main control.
Set employee communication timelines. Draft the written notifications you’re required to send, including deadlines and required content, well before the tax year starts.
Model your cashflow for earlier Class 1A NICs payments. Factor in the possible 2027 overlap, where you’re paying under both the old and new systems in the same period, and consider short-term funding if the timing gap is tight.
Pro Tip: Don’t wait for the March before go-live to test your payroll software. Run a dummy payrolling cycle for your Phase 1 benefits at least two full pay periods before the switch, so any FPS mapping errors surface while you still have time to fix them.
What this means for employees and your ongoing obligations
Employees will typically see tax deducted earlier once a benefit is payrolled, because the taxable value gets spread across the year rather than adjusted retrospectively through a tax code change. HMRC’s online service updates tax codes automatically for payrolled employees, which usually smooths this out, but it’s worth flagging the change to staff before their first payslip looks different.
For employers, Class 1A NICs don’t disappear. They simply move from a single annual payment to in-year payroll contributions, which changes how you plan cashflow across the year rather than reducing what you owe.
A few operational points are easy to miss:
P11D and P11D(b) still apply for any benefit that isn’t payrolled, including accommodation and loans, so you’ll likely be running both systems side by side.
The overriding limit matters: employers must not deduct more than 50% of an employee’s cash pay for tax on a payrolled benefit in any one period. If a deduction would breach that limit, you must exclude the employee from payrolling for that benefit and fall back on P11D reporting.
Watch the edge cases: employees making good on a benefit’s cost, irregular pay periods, secondments, and group companies supplying benefits across entities all need careful handling to avoid double reporting or missed liabilities.
Our recommended sequencing for the 2027 transition
Start with the benefits that carry the most value and the most risk. Company cars and medical cover sit in Phase 1, so audit those first and get your payroll software tested against real data well before the 2027 deadline. Most small and mid-sized employers can manage that groundwork internally with a clear checklist.
Where it gets genuinely complicated is internationally mobile staff, optional remuneration arrangements, or group structures where more than one company supplies benefits to the same employee. Those situations create real risk of double reporting or missed NICs liabilities, and that’s precisely where a second opinion from an adviser earns its keep rather than being an unnecessary cost.

FAQ
What is payrolling of benefits?
Payrolling adds the taxable value of a benefit in kind, such as a company car or medical insurance, directly into an employee’s pay so tax is deducted through payroll instead of via a year-end P11D form.
When does payrolling benefits become mandatory?
Phase 1 starts on 6 April 2027 and covers benefits making up around 92% of P11D value, with full mandatory coverage following by April 2028.
Which benefits cannot be payrolled?
Employer-provided living accommodation and beneficial or low-interest loans remain outside mandatory payrolling and must still be reported via P11D.
How do I register for payrolling benefits?
You register through HMRC’s online payrolling service, where you can also view registered benefits and exclude specific employees for a tax year.
Does payrolling remove the employer’s Class 1A NICs liability?
No. Employers still owe Class 1A National Insurance on payrolled benefits, but the payment moves from one annual sum to in-year payroll payments, which changes cashflow timing rather than the amount owed.
What happens if a payrolled deduction would exceed 50% of pay?
Employers must not deduct more than 50% of an employee’s cash pay for tax on a benefit in one period; if that limit would be breached, the employee is excluded from payrolling for that benefit and reported via P11D instead.
