HMRC Joint Responsibility Rules for Umbrella Companies — What Changes in April 2026?
From 6 April 2026, new legislation introduced by HM Revenue & Customs (HMRC) will significantly change how tax responsibility works when workers are engaged through umbrella companies.
The new rules introduce joint responsibility across the labour supply chain for PAYE tax and National Insurance contributions (NICs). This reform is designed to tackle non-compliance in the umbrella company market and ensure accountability for all parties involved in the supply of temporary workers.
For recruitment agencies, healthcare providers, and contractors, these changes represent an important shift in compliance obligations.

Below, we explain what the new legislation means and how it may affect you.
What Is Changing in April 2026?
The new legislation introduces Joint and Several Liability (JSL) for PAYE and National Insurance where umbrella companies are used within a labour supply chain.
This means:
-
HMRC can pursue multiple parties for unpaid tax.
-
Each party can be held responsible for the full amount owed, not just their share.
-
Liability can move beyond the umbrella company to other organisations involved in supplying the worker.
Previously, the umbrella company (as the employer) carried primary responsibility. From April 2026, this responsibility expands across the supply chain.
Why Is HMRC Introducing These Changes?
HM Revenue & Customs (HMRC) is introducing joint responsibility rules following significant evidence of tax loss and widespread non-compliance in parts of the umbrella company market, including tax avoidance schemes, unpaid PAYE, and fraudulent labour supply structures. The rapid growth of umbrella company usage — particularly following IR35 reforms — has increased these risks and exposed gaps in existing legislation.
The changes aim to:
-
Reduce tax avoidance and fraud — tackling disguised remuneration schemes, payroll manipulation, and unpaid employment taxes.
-
Protect workers — preventing individuals from facing unexpected tax liabilities due to non-compliant umbrella arrangements.
-
Improve market standards — ensuring compliant providers are not undercut by fraudulent operators.
-
Hold those with supply chain control accountable — placing responsibility on agencies and end clients that choose umbrella providers.
-
Close compliance gaps following IR35 reforms — strengthening employment tax oversight across contractor engagement models.
-
Protect public finances — reducing tax losses and improving labour market integrity.
Overall, the reform forms part of a wider government effort to strengthen transparency, fairness, and accountability in the temporary workforce sector.
Who Will Be Responsible?
The new rules determine responsibility based on the structure of the labour supply chain.
Recruitment Agencies
Where a recruitment agency supplies a worker through an umbrella company:
-
The agency with the direct contract with the end client becomes responsible for ensuring PAYE and NICs are correctly operated.
-
If tax is not paid correctly, HMRC may recover the debt from the agency.
This creates a significant new compliance obligation for agencies.
End Clients
Where there is no agency in the supply chain:
-
The end client engaging the worker becomes responsible for ensuring tax compliance.
This ensures accountability even where workers are engaged directly.
Umbrella Companies
Umbrella companies remain responsible as the formal employer, but:
-
They are no longer the only party HMRC can pursue.
-
Liability now extends to other parties involved in the engagement.
Understanding the Umbrella Company Supply Chain
How Joint Liability Works in Practice
Under joint and several liability, If an umbrella company fails to pay PAYE or NICs correctly, HMRC can recover the full amount not only from the Umbrella Company, but also from the other parties involved in the supply of a temporary worker.
Importantly:
-
HMRC can choose which party to pursue.
-
Responsibility applies even if another party caused the non-compliance.
-
There is limited ability to rely on “reasonable care” as a defence.
This makes supply chain due diligence essential.
What This Means for Recruitment Agencies and Healthcare Providers
Organisations using umbrella companies must prepare now for April 2026, including the below key considerations.
Stronger Due Diligence
-
Review umbrella company compliance processes.
-
Verify PAYE and NIC procedures.
-
Monitor payroll practices regularly.
Contractual Protection
-
Update contracts with umbrella providers.
-
Include compliance warranties and indemnities.
-
Clarify tax responsibility within supply agreements.
Supply Chain Transparency
-
Understand the full labour supply chain.
-
Avoid complex or unclear intermediary structures.
Ongoing Compliance Monitoring
-

-
Maintain clear documentation of compliance steps.
What This Means for Workers
For contractors and healthcare professionals working through umbrella companies, these changes aim to:
-
improve protection against tax non-compliance.
-
provide greater transparency in pay calculations.
-
require agencies and clients to become more selective about approved umbrella providers.
Preparing for April 2026
The introduction of joint responsibility represents one of the most significant changes to umbrella company regulation in recent years. Agencies, end clients, and umbrella companies must begin reviewing their engagement models now to ensure they meet the new requirements.
Early preparation will help minimise risk, protect supply chains, and ensure continued compliance.
To ensure full compliance with the new legislation and to protect both our workers and clients, we will be:
-
Reviewing and updating our Preferred Supplier List (PSL) of approved umbrella companies.
-
Working only with umbrella companies that hold certification from SafeRec (a recognised industry standard for transparency and compliance).
-
Offboarding any umbrella companies that do not meet these requirements.
Supporting our workers through this change, ensuring full and accurate information is given and compliant options available
