Joint and Several Liability — what changes from April 2026 and what it means for contractors
Direct Answer
From April 6th 2026, new legislation makes recruitment agencies liable for unpaid PAYE and NICs where non-compliant umbrella companies or other intermediaries fail to pay. This is Joint and Several Liability (JSL). If you work through an agency, your agency now has skin in the game — which changes how agencies assess and manage their supply chains. As a limited company contractor, understanding where liability sits in your engagement matters more than ever.
What is Joint and Several Liability?
New law from April 6th 2026 (Finance Bill 2026) fundamentally changes where HMRC can pursue unpaid tax in a supply chain. Where a worker's tax isn't paid in the supply chain, HMRC can pursue the recruitment agency — not just the umbrella or intermediary at fault.
Previously, liability sat with whoever failed to operate PAYE — often an intermediary that had disappeared or had no assets. JSL gives HMRC a solvent target higher up the chain: the agency.
Why does this matter to limited company contractors?
If you work through a recruitment agency, your agency now carries increased compliance risk for the supply chain below them. Agencies will respond by tightening their due diligence on intermediaries and payment models.
Contractors may face more scrutiny of their payment arrangements. Legitimate outside-IR35 limited company contractors operating correctly are not the target — but understanding the landscape protects you.
What has changed in practice?
Agencies are reviewing their supply chains ahead of April 6th. Some agencies are already requiring contractors to confirm their payment model and IR35 status in writing.
Having your IR35 status properly assessed and documented becomes more important. Keep your SDS on file (see our SDS guide below). Working through a compliant, properly structured limited company with a good accountant reduces your exposure.

Does JSL mean your agency will reassess your IR35 status?
No. This is the most important clarification for limited company contractors right now.
A growing misconception is circulating among recruitment agencies and end-clients that JSL requires a reassessment of worker status under IR35. This is incorrect.
JSL is a separate piece of legislation — Chapter 11 of the Income Tax (Earnings and Pensions) Act. It applies specifically to umbrella company arrangements where workers are paid via PAYE through an intermediary. It is not an extension of IR35 and does not require any reassessment of employment status.
Workers engaged via an umbrella company are employees of that umbrella, paid via PAYE with tax and NICs accounted for at source. The off-payroll working rules — IR35 — do not apply to these arrangements, and JSL does not change this.
If your agency tells you JSL requires an IR35 review, they are confusing two separate regimes. If you work through your own limited company outside IR35, JSL does not apply to your arrangement.
Could JSL actually work in favour of limited company contractors?
Possibly — and this angle is being underreported.
JSL imposes strict liability on agencies for PAYE failures by umbrella companies they work with. Crucially, there is no statutory defence based on due diligence — meaning an agency cannot escape liability by claiming they checked the umbrella and it looked compliant. They are liable regardless.
As a result, some agencies are reviewing their supply chains specifically to reduce umbrella exposure. A compliant outside IR35 limited company contractor represents zero JSL risk to an agency. The contractor pays their own tax. There is no PAYE obligation in the supply chain for JSL to attach to.
If agencies shift away from umbrella arrangements — and early signs suggest some are considering this — demand for properly structured limited company contractors increases. Agencies that previously pushed umbrella arrangements for convenience may become more open to genuine PSC engagements.
Understood correctly, JSL reinforces the value of operating through a properly managed limited company with a correct IR35 status. It is not a threat to compliant contractors — it is a problem for non-compliant intermediaries and the agencies that use them.
What the industry is saying
IR35 specialist firm Qdos published a useful analysis of the distinction between JSL and IR35 on LinkedIn, noting that JSL is causing significant confusion among agencies and end-clients — and that reassessment of IR35 status is not required under the new rules.
