What Is Joint and Several Liability?
Joint and several liability (JSL) means that where an umbrella company fails to pay the PAYE and National Insurance due on a worker’s earnings, HMRC can recover that unpaid tax from another party in the labour supply chain — typically the recruitment agency, and in some cases the end client. Since 6 April 2026, JSL has been the enforcement backbone of the reformed umbrella market, sitting alongside the new PAYE rules delivered through amendments to ITEPA 2003.
In plain terms: if the umbrella defaults, the agency can be made to pay. The debt does not disappear when a non-compliant provider dissolves.
Why JSL Changed the Risk Calculation
Before 6 April 2026, an agency could argue that payroll compliance was the umbrella’s problem. Joint and several liability removed that argument. The agency that supplies the worker is now financially exposed to the umbrella’s failures, whether those arise from fraud, insolvency or simple error.
Professional-services analysis described the reform as ushering in “a new era of joint and several liability” for the sector. The practical effect is that due diligence has stopped being a reputational nicety and become direct financial self-protection.
How Should Agencies Manage JSL Exposure?
Managing JSL exposure requires continuous assurance, not a one-off check at onboarding. FCSA recommends agencies build a structured due-diligence framework covering:
- Provider verification — confirm the umbrella is a genuine trading entity with clean beneficial ownership, not a short-life shell.
- Payroll evidence — obtain proof that Real Time Information submissions are being made and that deductions match what workers actually receive.
- Ongoing monitoring — repeat checks on a scheduled basis, because a provider that was compliant at onboarding can drift.
- Contractual protection — secure indemnities and information-sharing clauses, while recognising that an indemnity from an insolvent umbrella is worthless.
- Supply-chain visibility — ensure no undisclosed intermediaries or mini-umbrella structures sit beneath your named provider.
Why Indemnities Alone Are Not Enough
Agencies sometimes assume a contractual indemnity neutralises JSL. It does not. If the umbrella is insolvent, the indemnity cannot be enforced, and HMRC will pursue the solvent party. The only durable protection is placing workers with providers whose compliance can be independently verified before problems arise.
The Role of Verified Standards
Joint and several liability rewards agencies that can demonstrate genuine, evidenced due diligence. FCSA Accreditation gives agencies an independently assessed benchmark: providers are tested against the FCSA Codes covering payroll, tax treatment and worker rights before accreditation is granted, and are subject to reassessment.
Accreditation does not transfer an agency’s statutory liability — no scheme can. What it does is materially reduce the likelihood of partnering with a defaulting provider, and it gives the agency a defensible record of the care it took. That record matters when HMRC examines a supply chain.
Agencies can confirm a provider’s current status on the FCSA Members register.
FCSA’s Position
Joint and several liability is the mechanism that gave the 6 April 2026 reforms teeth. It has ended the era in which agencies could outsource payroll risk and look away. The party that supplies the worker now owns the consequences of a bad supply chain.
FCSA’s view is straightforward: JSL must be met with disciplined, evidence-led due diligence and a preference for independently assessed providers. To reduce your exposure, work with FCSA Members and verify accreditation through the FCSA Members register before you place a single worker.
