What is Changing
The UK government is mandating that most Benefits in Kind (BiKs) and related expenses are reported and taxed in real time through payroll software from 6 April 2026 (reporting) and will become mandatory for most BiKs from 6 April 2027.(gov.uk)
Until now, many BiKs have been declared using end-of-year forms (P11D / P11D(b)), with Class 1A NICs paid separately. Under the new system, BiKs (excluding certain employment-related loans and living accommodation initially) will be reported via payroll. However, from April 2027, loans and accommodation biKs will also be brought in but under a voluntary process initially.(gov.uk)
Timeline & Key Deadlines
- 5 April 2026: final date for employers to register for voluntary payrolling of BiKs for the 2026-27 tax year, especially for loans and accommodation. After this date, the voluntary registration tool closes.(gov.uk)
- 6 April 2026: All real time reporting via payroll required for most BiKs (excluding loans and accommodation).(gov.uk)
- 6 April 2027: Mandatory payrolling for most BiKs & expenses; loans & accommodation also included under the new rules (with timeline).(gov.uk)
Who’s Affected Most
- Employers of all sizes who offer benefits to employees—company cars, vouchers, health insurance, etc.
- Payroll software providers—must ensure systems handle real-time reporting, value calculations, submission via FPS (Full Payment Submission).
- Employees receiving BiKs—will see changes in how tax is deducted, possibly different tax codes, closer alignment between value and tax paid in same year provided.
Practical Implications & Real-World Example
Example: Acme Ltd provides a company car and private medical cover to its sales director. Under old system: the sales director receives a P11D end of the year; tax is collected via tax code the following year. Under new rules: from April 2026, most BiKs (car, medical) would be reported in real time via payroll software. From April 2027, even accommodation or loans (e.g. interest-free) get included. The director’s monthly deductions may increase in the year of receipt.
Preparation & Action Plan
- Audit all types of BiKs your employees receive. Classify which are currently reported via P11D and which will need to shift to payroll.
- Upgrade or validate payroll software to ensure it can handle Full Payment Submissions including BiKs and Class 1A NICs.
- Review internal HR & payroll workflows to ensure benefit providers feed timely data into payroll before the tax year ends.
- Communicate proactively with employees—explain how their pay packets and tax codes may change.
- Budget for transitional cashflow implications: overlapping liabilities may occur (employers paying tax for 2026-27 under P11D while starting new deductions for the same year’s BiKs).(gov.uk)
Risks, Opportunities & Best Practices
- Risk of misreporting or missing deadlines: penalties likely after full implementation from April 2027.
- Opportunity for cleaner payroll & fewer forms: streamlined admin and clarity for employees.
- Best practice: early voluntary registration for loans & accommodation BiKs to smooth transition and test systems.
- Use this change as impetus to review entire benefits programme: evaluate whether certain benefits are still cost-effective once tax and NI are accounted for in real time.
This move toward real-time reporting underscores the UK tax system’s push for fairness and modernisation. Employers who stay ahead will reduce risk and optimise their payroll processes.
