From 6 April 2026, new HMRC rules changed who can be held responsible for unpaid PAYE tax and National Insurance on umbrella company workers. If your business uses recruitment agencies or umbrella companies to engage contractors — or you’re a contractor working through one — this shift in liability could land an unexpected tax bill on your desk. Here’s what has actually changed, who it affects and what to do about it now.

What Is an Umbrella Company?

An umbrella company sits between a worker and the business that needs their services, usually with a recruitment agency in the middle. The umbrella company formally employs the worker, runs their payroll and deducts PAYE and National Insurance before paying their wages. Many contractors, locum professionals and temporary workers are engaged this way because it removes the need for the end client to run payroll for someone they may only need for a few weeks or months.

In practice, the chain often looks like this: an end client needs short-term staff, so it contracts with a recruitment agency, who finds a worker and introduces them to an umbrella company. The umbrella company employs the worker, invoices the agency for hours worked, and the agency in turn invoices the end client. Money — and PAYE responsibility — flows back down that same chain.

What’s Changed From 6 April 2026

The headline change is the introduction of joint and several liability (JSL) for PAYE and National Insurance owed by umbrella companies. Under the new PAYE rules for labour supply chains, if an umbrella company fails to pay HMRC what it owes, HMRC can now pursue the recruitment agency in the supply chain — or the end client if there is no agency involved — for the shortfall.

Why the Government Made This Change

HMRC has flagged a pattern of tax avoidance within parts of the umbrella company market for several years, including schemes that disguise remuneration or under-declare PAYE liabilities. By moving the financial risk further up the supply chain, the Government is betting that agencies and end clients will apply far more scrutiny to which umbrella companies they work with — effectively turning every business in the chain into an unpaid compliance checkpoint.

How the Liability Chain Now Works

There’s no opt-out available to an agency or end client once a JSL debt has arisen — HMRC’s decision to collect turns entirely on whether the umbrella company itself has paid up, not on anything the agency or client did wrong. That’s what makes this change so uncomfortable: a business can run flawless due diligence and still be pursued for someone else’s unpaid tax.

Who Is Affected by the New Rules?

Recruitment and Employment Agencies

Agencies now carry direct financial exposure for any umbrella company they place workers with. A shortfall in PAYE or NICs from that umbrella can be collected from the agency, regardless of the terms of the commercial contract between them.

End Clients / Hirers

Where no agency sits in the chain — or the agency cannot cover the debt — the end client can be the party HMRC turns to. This matters even for businesses that believe they’ve outsourced all payroll risk to a third party.

Umbrella Companies

Umbrella companies should expect tighter contractual terms, more frequent payslip and payroll audits, and closer questioning from the agencies and clients they work with, as those businesses now have a direct financial stake in the umbrella’s compliance.

Contractors and Workers

Day-to-day pay and deductions shouldn’t change for the worker. However, agencies and end clients may restructure how they engage contractors going forward, including a closer look at employment status and IR35 where a Personal Service Company is used instead of an umbrella arrangement.

What Hasn’t Changed

The mechanics of PAYE itself are untouched. The umbrella company remains the first port of call for operating payroll, deducting tax and NICs, and paying workers net of these deductions. JSL is a fallback collection power for HMRC — it doesn’t rewrite who is meant to pay in the first instance, only who else can be asked to if that first party fails to.

When the New Rules Don’t Apply

HMRC’s published guidance sets out several exclusions from the JSL rules:

• Payments made before 6 April 2026.
• Workers engaged through their own Personal Service Company (PSC), where IR35 rules may already apply.
• Workers employed by a Managed Service Company (MSC) — separate existing rules already allow HMRC to pursue MSC directors or providers.
• Members of Limited Liability Partnerships (LLPs).
• Certain deemed agency worker arrangements.

Practical Steps for Agencies and End Clients

• Map your full labour supply chain and identify every umbrella company currently in use.
• Add contractual clauses giving you audit rights and indemnities over PAYE and NICs compliance.
• Request and review sample payslips periodically to confirm deductions look correct.
• Cross-check any umbrella company against HMRC’s list of named tax avoidance schemes, promoters, enablers and suppliers and avoid offshore arrangements altogether.
• Agree clearly, in writing, which party in the chain is responsible for what — and revisit this annually.

Alternatives to Engaging Workers Through an Umbrella Company

For businesses uncomfortable with the residual risk, there are other ways to take on flexible labour, each with its own trade-offs:

• Direct employment — the most straightforward option, but it means running your own payroll and taking on full employer obligations.
• Self-employed contractors — workers invoice you directly, though their employment status still needs checking carefully.
• Engaging a worker’s own limited company (PSC) — brings IR35 / off-payroll working rules into play instead.

Frequently Asked Questions

Are umbrella companies being banned?

No. Umbrella companies remain a legal way to engage workers. What’s changed is that HMRC can now recover unpaid PAYE and NICs from the agency or end client if the umbrella company itself doesn’t pay.

Do recruitment agencies now have to run payroll themselves?

No. The umbrella company still runs payroll in the first instance. The agency only becomes liable if the umbrella fails to settle its PAYE and NICs bill with HMRC.

What should contractors do differently?

Very little changes for the worker’s own pay. However, agencies or clients may ask more questions about your engagement, or move towards different structures. If you’re unsure what you’re being asked to sign, it’s worth getting independent tax advice before agreeing to anything.

What happens if HMRC discovers underpaid PAYE?

HMRC will first look to the employment agency in the chain to settle the debt. Where there’s no agency, the end client becomes liable instead. This makes proactive due diligence far cheaper than dealing with an HMRC tax investigation after the fact.
