From 6 April 2026, there’s a significant shift in how umbrella companies will be treated under UK tax and labour law, and that change matters if you work with agencies that sometimes use umbrellas in their supply chains. These aren’t hypothetical tweaks, they represent a structural change in risk and accountability for anyone engaging contingent labour through intermediaries
Historically, umbrella companies have been a common way for agencies to employ and pay temporary workers. The umbrella handles payroll, deducts tax and National Insurance, and the agency (and ultimately the end client) can engage labour without taking on payroll responsibility directly. But under the new rules, that simplicity changes.
The core of the legislation is what’s known as joint and several liability. Under this framework, if an umbrella company fails to deduct and pay the correct PAYE income tax or National Insurance on a worker’s pay, HMRC can pursue any party in that labour supply chain, including the recruitment agency or even the client, for the full amount owed.
In practice, that means if an umbrella company in the chain has not complied correctly with PAYE obligations, HMRC will look to recover the liability from the agency that contracts with the client. In some cases , for example, where there isn’t a UK recruitment agency in the chain, that responsibility could fall on the end client directly.
Importantly, these rules apply to both new and existing arrangements from the start date, so simply continuing with familiar umbrella arrangements without review won’t insulate you from this change.
This shift reflects a broader government push to tackle non-compliance in the umbrella sector, closing loopholes, addressing tax avoidance and ensuring that labour supply chains operate properly for workers and for the tax system. While compliant umbrella companies shouldn’t see disruption, the risk for clients and agencies lies where compliance hasn’t been robust or transparent in practice.
What does this mean for organisations using agency supply?
- Due diligence matters more than ever. Agencies and clients alike need to be confident that any umbrella company in the chain is meeting its tax and payroll obligations.
- Payroll structures become a point of risk as well as service choice. Using an in-house payroll solution, like Employ’s model, where the agency itself handles payroll directly, removes reliance on an intermediary umbrella and the associated shared liability.
- Checking compliance isn’t optional. In the coming months, reviewing how your agency partners structure labour supply especially where umbrellas are involved, should be a priority.
This isn’t about alarm, and it isn’t about sudden change — it’s about recognising that the regulatory environment around contingent labour is evolving. Organisations that understand what’s shifting now can act with clarity and confidence, rather than react under pressure after April 6.
