The increase in National Insurance Contributions (NICs) for employers from April 2025 has sparked understandable concerns among businesses, many of whom may look to self-employed workforce models to manage costs. However, implementing such models requires careful navigation, especially given HMRC’s heightened focus on compliance and the risks associated with improper practices like mini umbrella schemes (MUCs). Here’s how businesses can approach this strategically and responsibly:
1. Understand and AVOID Mini Umbrella Schemes (MUCs)
Mini umbrella schemes involve splitting a workforce across multiple small companies to exploit tax breaks or lower NICs fraudulently. HMRC views this as a serious compliance breach. To steer clear:
- Educate your team on the warning signs of MUCs, such as unusually low prices from agencies or complex supply chains.
- Vet labour supply chains thoroughly to ensure compliance and transparency.
- Work with trusted partners for payroll services who adhere to best practices, who have a wealth of experience such as EEBS.
- Hybrid models: Consider employing a mix of permanent staff and contractors to balance flexibility and compliance.
2. Ensure Robust Compliance Processes
With HMRC increasing its investigative capacity, businesses should regularly strengthen their compliance:
- Audits: Regularly review your workforce arrangements and supply chain for compliance.
- Documentation: Maintain clear contracts and evidence of genuine self-employment or employment relationships.
- Expert advice: Engage tax and legal advisors to ensure your models align with IR35 and other HMRC regulations.
