How Technical Resources Helped a Client Stay Compliant with New JSL Legislation
With the new JSL tax law from 6 April 2026, businesses using subcontractor labour faced more scrutiny on payroll compliance, tax deductions, and National Insurance liability. Many suddenly faced new financial and administrative risks.
This case study shows how Technical Resources delivered a compliant subcontractor payroll solution that cut risk, eased administration, and improved payments for both client and workforce.
The Challenge: Managing Subcontractor Payroll Compliance Under JSL Legislation
Following the implementation of the new JSL legislation in April 2026, our client became increasingly concerned about their direct subcontractor labour model.
The business understood that it could be held liable for unpaid tax and National Insurance contributions across its labour supply chain if the correct compliance procedures were not followed.
The client faced several operational challenges:
- Limited internal infrastructure to carry out the necessary due diligence on subcontractor payments
- Growing concerns around payroll compliance and HMRC risk exposure
- Over 50 supplier payments are being processed each month.
- Significant administrative pressure was placed on their accounts team.
- The need to maintain uninterrupted contractor engagement during legislative changes
The client required a trusted payroll partner that could deliver a fully compliant solution while reducing internal workload and protecting the business from tax liability.
The Solution: A Fully Compliant Payroll and Paymaster Service
Technical Resources implemented a tailored subcontractor payroll solution designed to align with the new JSL requirements.
Acting as the paymaster, Technical Resources took full responsibility for managing subcontractor payments on the client's behalf.
Our solution included:
- Managing the payment process for the client’s subcontractor workforce
- Delivering a fully compliant payroll model
- Ensuring the correct Tax and National Insurance deductions were made
- Providing complete transparency and reporting where required
- Supporting subcontractors directly with payroll and payment queries
- Reducing administrative burden for the client’s finance department
By outsourcing payroll management to Technical Resources, the client gained confidence that their subcontractor workforce was being managed in line with current legislation and compliance standards.
The Benefits: Reduced Risk and Improved Operational Efficiency
The new payroll structure delivered immediate operational and financial benefits for the client.
Risk Mitigation and Compliance
The client significantly reduced their exposure to tax and National Insurance liability across their subcontractor supply chain. Technical Resources ensured that compliant payroll processing and due diligence procedures were maintained throughout.
Improved Cashflow Flexibility
Flexible payment terms helped improve the client’s cash flow management while maintaining prompt payment to subcontractors.
Streamlined Accounts Administration
Instead of processing over 50 individual supplier invoices each month, the client was able to consolidate all subcontractor payroll costs into a single monthly invoice, dramatically reducing administrative workload for the accounts team.
Contractor Relationship Management
Technical Resources also took responsibility for managing subcontractor communication and resolving payroll queries, allowing the client to focus on core business operations.
The Results: Faster Payments and Business Continuity
The transition to the new payroll model was highly successful for both the client and their subcontractors.
Key outcomes included:
- Subcontractors received payment faster through Technical Resources than they had previously through direct client payment.
- The client achieved full confidence in their payroll compliance processes.
- Ongoing projects and workforce requirements continued without disruption despite the introduction of new JSL tax legislation.
- Both the client and subcontractors reported high satisfaction with the new arrangement.
By partnering with Technical Resources, the client was able to navigate complex legislative changes while improving efficiency, reducing risk, and maintaining a positive subcontractor experience.
