Effective April 6, 2027, all UK employers must report and pay Income Tax and Class 1A National Insurance contributions on employee benefits through payroll rather than annual P11D forms. The change affects up to three million employees and eliminates up to four million end-of-year returns. Employers must register with HMRC in advance of the 2026/27 tax year, audit payroll systems for PBIK compatibility, and prepare processes for real-time benefits reporting. Some benefits like company cars and loans above £10,000 may require specialist software alongside payroll systems. The implementation date was delayed from April 2026 to give employers additional preparation time.

UK Mandates Payrolling of Benefits in Kind from April 6, 2027

Effective April 6, 2027, all UK employers must report and pay Income Tax and Class 1A National Insurance contributions on employee benefits through payroll in real time, rather than filing annual P11D and P11D(b) forms. The implementation date was delayed from April 6, 2026 to provide employers additional preparation time. HM Revenue & Customs (HMRC) estimates the change will affect up to three million employees and eliminate up to four million end-of-year returns.

Who is affected

All UK employers that provide taxable benefits to employees are required to implement payrolling of benefits in kind (PBIK). The change impacts HR, payroll, and rewards teams responsible for benefits administration and tax reporting. Employers of all sizes must comply, regardless of headcount or industry.

What's changing

Current process	New process (from April 6, 2027)
Benefits reported annually on P11D forms (employees) and P11D(b) forms (employers)	Benefits reported and taxed through payroll in real time
Class 1A National Insurance contributions calculated and paid annually in July	Class 1A contributions calculated and paid via monthly payroll
Manual year-end reconciliation of benefits	Real-time benefits reporting integrated with payroll systems

Employers must transition from end-of-year P11D reporting to real-time payroll reporting. Some benefits—particularly company cars and employer-provided loans above GBP 10,000—may require specialist software or manual processes alongside standard payroll systems, as payroll platforms may not hold all necessary data in real time.

What NEO partners and clients should do

Register with HMRC for PBIK in advance of the 2026/27 tax year to avoid processing delays closer to the April 6, 2027 implementation date.
Audit payroll and benefits systems by Q4 2026 to confirm PBIK compatibility and identify benefits requiring specialist software or manual workarounds.
Coordinate between payroll, HR, and rewards teams to establish processes for capturing and reporting benefits data in real time, particularly for complex benefits such as vehicles and loans.
Monitor HMRC announcements for draft legislation and detailed guidance, expected before implementation.
