HMRC brings benefits-in-kind into RTI payroll, ending P11D rush and tightening pay-run data
The gist
Accounting teams are shifting from year-end benefits reporting to live payroll compliance, forcing tighter coordination between payroll, tax, and finance throughout the year.

HMRC Brings Benefits-in-Kind Into RTI Payroll
HMRC’s proposal makes benefits-in-kind a live payroll data problem with fixed dates: mandatory payrolling via RTI starts 6 April 2027 for company cars, car fuel, vans, van fuel, and employer-provided medical benefits, with most other benefits following in April 2028. That strips out much of the year-end P11D and P11D(b) cycle and pushes BiK values into each pay period’s Full Payment Submission. For finance teams, the real change is tighter synchronization across fleet, medical, HR, and payroll records so tax and Class 1A NIC are calculated as benefits arise, not corrected after year-end.
The same operating model is spreading beyond payroll. New Zealand has set 1 January 2027 for large government suppliers, defined as revenue above NZD 33 million in each of the prior two accounting periods, to use B2G e-invoicing under Peppol PINT A-NZ Billing via certified Access Points and NZBN routing. Belgium has confirmed mandatory domestic B2B structured e-invoicing from 1 January 2026 and a near-real-time e-reporting layer by 2028, while CRS 2.0 points in the same direction. The work is now moving one step further into continuous control, so accounting teams need stronger exception management, control design, and tax-IT coordination rather than period-end cleanup.
How should payroll, HR, and fleet teams prepare for RTI BiK?
If you're an individual contributor
- Year-end BiK cleanup is fading; live payroll control is the new value.
- Get sharp on RTI, P11D replacement logic, and exception checks—your edge is catching BiK errors before payroll runs.

If you manage a team
- Your team must shift from after-the-fact fixes to real-time control.
- Coach people on cross-checking fleet, HR, and payroll data; the team that spots BiK exceptions fastest will matter most.

If you lead the organization
- Manual year-end tax cleanup is becoming a weak operating model.
- Invest in payroll-tax data integration and control design now, or you'll keep paying for avoidable P11D, e-invoicing, and reporting errors.
