What JSL Legislation Actually Says About Recruitment Agencies

KPMG described the Finance Bill 202526 definition of “umbrella company” as covering any person “that carries on a business of supplying labour,” a definition so wide that it alarmed the entire recruitment sector. But the alarm, while understandable, misreads where the JSL legislation 2026 actually points. Deloitte has been clear: agencies running their own PAYE under Section 44 ITEPA 2003 are “fully in control of their own risk.” The definition is broad. The liability is targeted. Those two things can both be true. 

This article sets out the statutory position, the professional consensus, and what the absence of case law means for healthcare recruiters right now. 

The Finance Bill 202526 and Chapter 11 

The Finance Bill 202526 inserts a new Chapter 11 into Part 2 of the Income Tax Earnings and Pensions. Act 2003. Chapter 11 creates joint and several liability between agencies, end clients, and umbrella companies for unpaid PAYE and National Insurance where a worker is supplied through an umbrella arrangement. 

The effective date is 6 April 2026. From that point on, if an umbrella company fails to operate PAYE correctly, liability does not rest solely with the umbrella. It travels up the supply chain to the agency or end client that engaged the umbrella. That is the mechanism. That is what joint and several liability April 2026 means in practice. 

The JSL Finance Bill provisions are not a standalone act. They are amendments to existing income tax legislation, bolted onto the ITEPA 2003 framework that has governed employment taxes since 2003. Understanding them means understanding where they sit within that framework, not reading them in isolation. 

Why the Definition Matters 

KPMG’s concern centres on drafting. The Finance Bill defines “umbrella company” as any person “that carries on a business of supplying labour.” KPMG noted this is “much wider than the type of business that might typically be referred to as an umbrella company.” On a plain reading, that definition could encompass a traditional recruitment agency.

The REC has framed JSL as targeting supply chains where an umbrella sits between the agency and the worker. That framing reflects the policy intent. The legislation was designed to close a specific tax avoidance route, not to reclassify the entire recruitment sector. 

But drafting ambiguity is real. And in tax law, what matters is not intent. It is the statutory language as written and, eventually, as interpreted by tribunals and courts. Right now, no court has interpreted it. That matters more than most commentary acknowledges. 

What Deloitte Says About Own-PAYE Agencies 

Deloitte’s position on this is the most practically useful guidance available. Agencies that employ workers directly and operate PAYE themselves under Section 44 ITEPA 2003 are operating a fundamentally different model from an umbrella arrangement. Deloitte’s analysis is that these agencies are “fully in control of their own risk.” 

The logic follows from how Chapter 11 ITEPA is constructed. The new JSL provisions apply where an umbrella company is engaged in the supply of a worker. If there is no umbrella in the chain, there is nothing to trigger the liability shift. A comparison of an own-PAYE agency vs an umbrella company under JSL makes this structural difference plain. 

Section 44 of ITEPA 2003 already places the PAYE obligation on the agency that employs the worker directly. Chapter 11 does not disturb that. It creates an additional liability layer for scenarios where the agency has outsourced that obligation to an umbrella. If you have not outsourced it, the layer does not attach. 

HMRC’s Published Position 

HMRC’s published guidance states: “The agency or end client will be responsible for making sure PAYE is operated correctly, when an umbrella company employs their workers.” The conditionality in that sentence is doing significant work. The responsibility attaches when an umbrella company employs the workers. Not otherwise. 

HMRC has not published guidance classifying a Section 44 agency as an umbrella company. The published position is consistent with Deloitte’s analysis: liability flows from the umbrella engagement, not from direct employment. 

For JSL recruitment agencies trying to establish their compliance position, the HMRC guidance is a useful anchor. It is not a guarantee. Tax law does not work on guarantees. But it is the clearest official statement of where the risk sits, and it sits with umbrella arrangements. 

No Case Law. No Precedent. No Tested Interpretation. 

What is JSL legislation 2026 has not been tested. Chapter 11 does not come into force until 6 April 2026. No tribunal has ruled on whether a particular agency structure falls within or outside the umbrella definition. Nothing. 

That is the honest position. Professional firms offer analysis and interpretation. That analysis is credible and worth taking seriously. But it is not settled law. 

This uncertainty has practical implications. Well-advised agencies with clean own-PAYE structures should be documenting their position now. Not because liability is likely, but because documentation is how you demonstrate your reasoning if HMRC ever asks. A JSL due diligence defence position is built before the legislation takes effect, not after.

Frequently Asked Questions 

What does JSL stand for in recruitment? 

JSL stands for joint and several liability. In a recruitment context, it refers to the principle that more than one party in a supply chain can be held liable for unpaid PAYE and National Insurance. The Finance Bill 202526 introduces

JSL provisions specifically targeting supply chains that involve umbrella companies. 

When does JSL legislation take effect? 

The Chapter 11 ITEPA 2003 provisions introduced by the Finance Bill 202526 take effect on 6 April 2026. 

Who is liable under JSL? 

Under the new Chapter 11 provisions, liability can extend to any party in the supply chain above the umbrella company. That means the recruitment agency that engaged the umbrella and, in some circumstances, the end client. Liability does not arise where no umbrella is engaged. 

Does JSL replace IR35? 

No. JSL and IR35 are separate frameworks addressing different issues. IR35 governs the employment status of individual contractors. JSL targets supply chains where umbrella companies are used to employ workers and where PAYE obligations may not be properly discharged.
