What’s changing: Real-Time BiK Reporting
The UK government has confirmed that mandatory payrolling of benefits in kind (BiKs) and taxable employment expenses via Real Time Information (RTI) payroll software will come into effect from 6 April 2027. This pushes back the earlier target of April 2026, allowing more time for adaptation. (gov.uk)
The reforms specifically include:
- Employers reporting both Income Tax and Class 1A National Insurance Contributions on BiKs in real time. (gov.uk)
- A voluntary registration service for payrolling employer-provided loans and resident accommodation benefits (often the most complex BiKs) starting around November 2026. (gov.uk)
Why This Matters
- Payroll software and HR systems will need to be updated to handle frequent, accurate reporting.
- Finance teams must understand how to value complex benefits (e.g. accommodation, loans) and work out tax liabilities correctly.
- Employees may see more consistent treatment throughout the tax year, rather than surprises at year-end.
- Non-compliance now will lead to penalties, so early preparation is a win.
What Employers Should Do, Step by Step
| Step | Action | Timeline |
|---|---|---|
| 1. Inventory your BiKs | List all benefits you give—loans, accommodation, company cars, etc.—and map current reporting methods. | Immediately – during fiscal year 2025-26 |
| 2. Assess valuation and payroll practices | Work out how to calculate taxable values under the new system; get your payroll software ready. | Over 2025 to mid-2026 |
| 3. Register for voluntary payrolling | Take advantage of early registration (November 2026) to pilot complex BiKs. | Before end of 2026 |
| 4. Train staff & stakeholders | HR, payroll, finance, and agents need to understand changes. | Mid--2026 on |
| 5. Update software providers | Ensure any software you use complies with RTI updates and HMRC requirements. | Ongoing leading up to 2027 |
Example Scenario
Imagine Alpha Ltd, which provides accommodation for senior executives plus low-interest loans for employees. Under the current rules, they itemize everything via P11D forms at year end. Under the new regime:
- They’ll need to payroll report these benefits throughout the year using RTI.
- They should register early for the voluntary regime in November 2026 to pilot the accommodation benefit reporting.
- They'll need to calculate Class 1A NICs during payroll runs, rather than once at the end of the year.
Keys to Smooth Transition
- Audit current BiKs to know where you stand.
- Engage with payroll or software providers early, confirming what updates are needed.
- Communicate changes to employees so they understand impacts during the year.
- Seek guidance documents from HMRC—drafts were published in November 2025, ahead of the final rules. (gov.uk)
Final Thoughts
Real-time reporting of BiKs is a big shift from annual, P11D-driven reporting. Admitedly a complex one—but if employers begin preparing now, with clear inventory, updated valuations, software capability, and strong documentation, the transition in April 2027 tends to be far less painful.
