HMRC’s approach to labour supply chains is shifting fast. By 2026, every business that uses agency labour – construction, logistics, manufacturing, security, care, hospitality and more – will face a far tougher standard of compliance.
The message from HMRC is simple:
If your supplier gets tax wrong, and you didn’t check them properly, you will be held responsible.
“I didn’t know” is no longer a defence.
“I didn’t check” is treated as negligence.
“I trusted the agency” will not protect you.
This is a fundamental change. And many businesses are still unaware of how exposed they are.
Why This Matters Now
HMRC has intensified its focus on labour supply chains because billions have been lost through:
- unpaid PAYE and NIC
- VAT fraud
- payroll outsourcing schemes
- phoenix agencies that disappear before tax is due
- umbrella company failures
- disguised employment and offshore intermediaries
In 2026, enforcement will become even more proactive. Expect more visits, more letters, more demands for evidence and far fewer second chances. HMRC will be testing and challenging your supplier engagement systems.
If your business relies on temporary labour, now is the time to tighten your controls.
The Key Change: Responsibility Sits With You
Historically, HMRC focused on the staffing agency.
From 2026, the engager – the business receiving the labour – will sit at the centre of the compliance risk.
HMRC expects you to:
- verify your suppliers
- understand their payment model
- review sample payslips
- request key documents
- check that PAYE and VAT obligations are being met
- keep clear audit trails
If you can’t evidence this, HMRC can (and increasingly will) transfer tax liabilities to you.
The Warning Signs HMRC Looks For
If any of the following appear in your supply chain, you are already on HMRC’s radar:
- unusually low charge-out rates
- workers receiving high net pay compared with industry norms
- payslips missing employer information
- offshore or unregistered intermediaries
- frequent bank-account or company-name changes
- umbrella companies with opaque structures
- agencies unwilling to explain how they operate
- pressure to approve invoices quickly
- workers complaining about deductions
Any one of these can trigger an enquiry. Several together almost guarantee it.
Why ‘I Didn’t Know’ Won’t Help You
HMRC’s position is clear:
- It is your responsibility to understand who is supplying the labour.
- It is your responsibility to check how workers are being paid.
- It is your responsibility to run due diligence checks.
- It is your responsibility to stop using a supplier if HMRC flags them.
If you fail to do this, HMRC assumes you ignored the risks.
What Happens When a Supplier Fails
When HMRC identifies a non-compliant staffing agency, the supply chain is reviewed.
If PAYE, NIC or VAT has not been paid, you can be hit with:
- transferred tax liabilities
- penalties up to 100%
- interest
- removal from Gross Payment Status (construction)
- assessments spanning multiple years
- a full supply-chain investigation
And increasingly, HMRC is issuing cease-using letters:
“If you continue to use this supplier, we will hold you responsible for the tax loss.”
Ignoring that letter guarantees liability.
What Businesses Must Do Before 2026
This is a year to prepare, tighten processes and document everything.
- Review every agency you use
Check registration, VAT numbers, PAYE details, directors, addresses, insurance, and payment models.
- Understand the payment structure
If you can’t explain it, that’s a red flag.
- Audit your own controls
Would your paperwork protect you in an enquiry?
- Check payslips and payment trails
Sample checks make a significant difference.
- Train your internal teams
Anyone involved in hiring or approving invoices must understand the risks.
- Build a compliance file for each supplier
HMRC expects to see clear, consistent evidence.

As Andy McKenna, tax investigations specialist at DSC Metropolitan, notes:
“HMRC doesn’t accept ignorance as a defence. They expect businesses to take an active role in policing their own supply chains. If suitable systems are not in place the business and the Directors may be exposed to an unexpected liability. ”
Ignoring this shift leaves you exposed to penalties, investigations and reputational damage.

Final Thoughts
2026 will be a turning point for labour supply chains.
HMRC’s expectations are higher.
Checks must be deeper.
Documentation must be stronger.
If you rely on temporary labour, the question is no longer “Is there a risk?”. The question is:
“Are we able to prove we took reasonable steps?”
If you’re unsure, we can help you strengthen your systems before HMRC enforcement escalates.
