From 6 April 2026, major changes to umbrella company legislation come into force for the UK recruitment sector and how it manages tax obligations. Under new rules in the Finance Bill 2025/26, recruitment agencies can be held jointly and severally liable for unpaid PAYE tax and National Insurance contributions where umbrella companies sit within the labour supply chain.

Joint and Several Liability (JSL) allows HMRC to pursue any relevant party, not just the umbrella, for the full amount of unpaid tax, including income tax and National Insurance. This marks a significant change in the compliance landscape for the temporary labour market.

These changes apply specifically to UK recruitment businesses, MSPs, and end-client businesses that engage workers through umbrella providers. With the legislation now in force, agencies must urgently review their supply chain, strengthen due diligence, and ensure alignment with the new liability rules.

What is Joint and Several Liability and how is it changing in 2026

Joint and Several Liability means that if one party in the chain fails to meet its tax liabilities, others can be held responsible.

For example, if an umbrella company doesn’t pay £75,000 in PAYE tax and National Insurance contributions, HMRC can recover the full amount from the recruitment agency, even if the agency has already paid the umbrella.

From April 2026, under new umbrella company legislation, this principle expands across the labour supply chain, meaning that Umbrella companies, agencies, and sometimes the end client may all be jointly and severally liable.

The rules apply specifically to temporary workers paid through umbrella structures and include both income tax and Class 1 National Insurance contributions.

Who will be affected in the labour supply chain?

The new rules extend across the labour supply chain, meaning multiple parties may be impacted.

• Recruitment agencies placing temporary workers.
• End client businesses engaging umbrella workers directly.
• Umbrella companies that employ and pay workers.
• MSPs and intermediaries acting as a relevant party.

Where a non-compliant umbrella company is involved, recruitment agencies responsible for placing workers may be held liable for unpaid PAYE, even if they were not directly at fault.

This significantly increases exposure for UK recruitment agencies operating within complex supply chain structures.

Defining an umbrella company

The new umbrella company legislation adopts a broad definition of how umbrella companies operate.

Typically, an umbrella company:

• Employs temporary workers.
• Receives funds from agencies or end clients.
• Processes payroll and tax payments.

What exactly changes on 6 April 2026?

From April 2026:

• Umbrella companies will remain responsible for payroll, but agencies and end clients will become jointly and severally liable.
• HMRC can pursue any relevant party for the full debt amount without first chasing the umbrella company.
• Applies where an umbrella fails to correctly account for PAYE tax, unpaid PAYE, or National Insurance contributions.

There is no contractual workaround, even if agreements state the umbrella is responsible, liability means HMRC can still recover from others in the chain.

This fundamentally changes risk exposure across the temporary labour market.

How HMRC will apply Joint and Several Liability in practice

HMRC will use real-time payroll data and intelligence to identify non-compliance within the umbrella company market.

If a non-compliant supply chain issue is detected:

• HMRC can issue assessments to agencies or the end client.
• Multiple parties may be pursued simultaneously.
• Each party becomes severally liable for the full amount.

Even where agencies have acted in good faith, failure to conduct robust due diligence could still result in unexpected tax bills.

Risk and impact analysis for recruitment agencies

The introduction of Joint and Several Liability rules creates several key risks.

Legal risk

Agencies can be held liable regardless of intent; strict statutory liability applies.

Financial risk

Exposure includes PAYE tax, National Insurance contributions, interest and penalties.

Operational risk

Removing non-compliant umbrella companies may disrupt worker pay and client delivery

Reputational risk

Association with non-compliant umbrella providers can damage trust across the recruitment sector

Agencies must adapt quickly to this evolving compliance landscape.

Implications for other stakeholders

• Compliant umbrella companies may benefit from reduced unfair competition.
• End client businesses will demand stronger compliance processes.
• Temporary workers gain greater certainty around correct tax treatment.
• The wider labour market becomes more regulated and transparent.

Practical steps for recruitment agencies to prepare before 6 April 2026

Preparation is essential. Agencies should:

Map the supply chain

Identify all parties in the labour supply chain, including umbrella partners.

Strengthen due diligence

Implement robust due diligence, including financial checks, transparency on ownership, and compliance history.

Review contracts

Ensure agreements include clear tax obligations, audit rights, and termination clauses for non-compliance.

Monitor ongoing compliance

Introduce ongoing compliance checks, including payslip audits, RTI verification, and evidence of correct tax payments.

Train internal teams

Ensure consultants understand joint and several liability and risks of non-compliant umbrella companies.

Reduce risk exposure

Consider limiting umbrella partners or moving workers to compliant PAYE models.

Document everything

Maintain records of all due diligence and compliance processes to demonstrate accountability.

Ultimately, agencies that prioritise due diligence, strong governance, and compliant supply chain practices will be best positioned to succeed under the new legislation.

Final thoughts

These changes represent one of the most significant regulatory shifts affecting umbrella companies, recruitment agencies, and the wider labour market in recent years.

With Joint and Several Liability placing real financial risk on agencies and end clients, proactive preparation is no longer optional; it is essential.

Now is the time to review your labour supply chain, eliminate non-compliant umbrella companies, and ensure your business is fully aligned with the new HMRC requirements.
