## Background on Class 1A NICs and Benefits in Kind (BiKs)
Class 1A National Insurance Contributions (NICs) are payable by employers on benefits-in-kind (e.g., company cars, accommodation, low-interest loans) and are typically picked up via P11D and P11D(b) returns. With more global mobility, questions arise when employees go abroad or are returning from abroad.([gov.uk](https://www.gov.uk/government/publications/cwg5-class-1a-national-insurance-contributions-on-benefits-in-kind/2026-class-1a-national-insurance-contributions-on-benefits-in-kind-termination-payments-and-sporting-testimonial-payments?utm_source=openai))
## What the New Rules Say (Published Feb 2026)
- When an employee **works wholly overseas** and is not UK resident, they may have **no taxable employment** during the overseas part of a split year. In such cases, benefits in kind provided for that period are **not taxable** in the UK and **not reportable**, thus **no Class 1A NIC** liability for the employer for those overseas days.([gov.uk](https://www.gov.uk/government/publications/cwg5-class-1a-national-insurance-contributions-on-benefits-in-kind/2026-class-1a-national-insurance-contributions-on-benefits-in-kind-termination-payments-and-sporting-testimonial-payments?utm_source=openai))
- If liability for Class 1 employer NICs ends part-way through the year due to reciprocal social security agreement or work duration abroad exceeding 52 weeks, the Class 1A NIC on BiKs must be prorated. Employers should use adjustment procedures via form P11D(b).([gov.uk](https://www.gov.uk/government/publications/cwg5-class-1a-national-insurance-contributions-on-benefits-in-kind/2026-class-1a-national-insurance-contributions-on-benefits-in-kind-termination-payments-and-sporting-testimonial-payments?utm_source=openai))
## Why This Matters for Employers
- Global assignments and remote work arrangements may change where and how BiKs are taxed and reported.
- Underreporting BiKs can lead to penalties; overreporting may cost more than necessary.
- Payroll systems must properly track residency, social security status, and the timing of employee departures/returns.
## Practical Compliance Steps
1. **Review employee assignments**: Identify staff working wholly overseas vs those working part UK/part abroad (split year).
2. **Assess social security agreements**: Whether UK has bilateral treaty with the country they work in may affect NIC liability.
3. **Update payroll & benefits tracking systems**: Ensure distinction of on-UK vs abroad days, and capture dates where UK liability ends or resumes.
4. **Use proper forms & documentation**: Form P11D(b) adjustments, correct coding, documentation of overseas work periods.
5. **Training & policies**: Make sure HR, payroll teams, and finance are aware of these changes—especially in multinational businesses.
## Example Scenario
Darren works for a UK firm and moves to Germany for a 14-month assignment. UK’s social security agreement with Germany holds. From month 13 onwards (52 weeks abroad), UK NIC liability ends. Any BiKs provided after that point should not be reported for UK class 1A NICs for that period. The company must prorate BiK value and the NIC charge only for the period where UK liability remains.
If instead, someone works abroad but is still classed as UK resident and no social security agreement applies, UK NIC liability may continue, and BiKs during entire period may remain taxable.
## Conclusion
Employers with globally mobile workforces need to pay close attention: recent guidance clarifies when BiKs are taxable and when they are not, depending on residency, duration of overseas work, and applicable treaties. Proper tracking, accurate reporting, and clear policies are essential to avoid surprises or penalties.
