The P11D is Dead: Transitioning to Mandatory Pay Rolling of Benefits in 2026
For decades, the P11D form was the bane of the finance department’s summer. HMRC has finally moved to simplify—and speed up—the collection of tax on employee perks. From April 2026, Pay rolling Benefits in Kind (BiK) is mandatory for all employers.
What Changes for Your Business? Under the old system, you reported benefits annually and HMRC adjusted the employee’s tax code the following year. Now, the tax is settled in “real-time.”
- Valuation: You must calculate the cash equivalent of benefits (private health, gym memberships, etc.) monthly.
- Deduction: This value is added to the payroll as “notional pay,” and PAYE is deducted immediately.
- Class 1A NIC: These are still payable by the employer, but the reporting is now integrated into your monthly Full Payment Submission (FPS).
The Electric Vehicle (EV) Transition Company car tax remains a significant focus. For 2026, the BiK rate for zero-emission vehicles has risen to 3%. While still highly incentivized compared to petrol vehicles (which can reach 37%), this 1% year-on-year increase must be reflected in your monthly payroll calculations to avoid year-end reconciliation issues.
Conclusion Mandatory pay rolling requires a “clean” data link between your benefits providers and your payroll department. At Payroll Guaranteed, we specialize in this integration, ensuring that your employees pay the right tax at the right time, eliminating the shock of tax code changes.
