IR35, Limited Company Contractors and the Changing Recruitment Landscape

What recruitment agencies need to know in 2026

The way recruitment agencies engage and pay contractors is receiving increasing attention.

The continued application of the IR35/off-payroll working rules, changes introduced from 6 April 2026 in relation to umbrella companies and labour supply chains, and recent employment-status case law all reinforce the importance of having a clear and properly managed contractor engagement process.

For recruitment agencies, the message is not that Limited Company contractors can no longer be used.

Far from it.

The important issue is understanding how the contractor is engaged, who is responsible for determining employment status, and how the payment and administration arrangements operate.

This article explains some of the key issues recruitment agencies should be considering in 2026.

What is IR35?

IR35 is the commonly used name for the UK's off-payroll working/intermediaries legislation.

Broadly, the rules are intended to address situations where an individual provides their services through an intermediary, commonly their own Personal Service Company (PSC), but the relationship would otherwise be one of employment if the individual had contracted directly with the client.

The question is therefore not simply:

"Does this contractor have a Limited Company?"

The more important question is:

"If the contractor had provided their services directly to the client, would the relationship have been one of employment?"

HMRC's guidance confirms that the existing employment-status principles continue to be relevant when determining whether the intermediaries legislation applies.

Who is responsible for the IR35 determination?

This is an important distinction for recruitment agencies.

Where the off-payroll working rules apply, responsibility for determining the worker's status depends on the circumstances of the engagement.

For public-sector engagements, the public authority is generally responsible.

For engagements with a medium or large private-sector client, the client is generally responsible for making the determination and issuing a Status Determination Statement (SDS).

The recruitment agency can also have important responsibilities within the chain, particularly where it is the fee-payer or otherwise falls within the relevant provisions.

This means recruitment agencies should not assume that simply having a contractor operate through their own Limited Company removes the need to consider IR35.

Equally, using a Limited Company contractor does not automatically mean the engagement is caught by IR35.

The circumstances of each engagement matter.

What changed on 6 April 2026?

One of the most significant changes affecting recruitment agencies came into force on 6 April 2026, under the new rules, where an umbrella company employs workers and forms part of the labour supply chain, the agency that has the contract with the end client can have joint and several liability for PAYE liabilities arising from the umbrella company's failure to operate PAYE correctly.

HMRC can recover underpaid PAYE from the relevant agency or end client in circumstances covered by the legislation.

This is a significant development for recruitment businesses that use umbrella companies.

It means agencies need to pay closer attention to their supply chains and the businesses involved in paying their workers.

Do the “new rules” apply to Limited Company contractors?

Generally, no — not where the contractor is genuinely providing their services through their own Limited Company or Personal Service Company (PSC).

The changes introduced from 6 April 2026 are specifically aimed at labour supply chains involving umbrella companies and address the way PAYE and National Insurance are operated where an umbrella company employs the worker.

HMRC's guidance makes clear that the new rules do not generally apply where the worker is employed through their own PSC, provided the relevant conditions are met.

This means recruitment agencies can continue to engage genuine Limited Company contractors without automatically bringing them within the new umbrella-company PAYE rules.

However, there is an important distinction:

The fact that a contractor operates through a Limited Company does not automatically mean the engagement is outside IR35.

IR35 and employment-status considerations remain separate. The nature of the engagement and the way the services are actually provided still need to be considered.

For recruitment agencies, the key takeaway is simple:

The 2026 changes have not removed the Limited Company contractor model. They have increased the importance of understanding how contractors are engaged, how their status is determined, and how payments are administered.

Why recent employment-status cases matter

Employment status has always been a fact-sensitive area, but recent cases continue to demonstrate why simply relying on contractual labels can be dangerous.

A particularly notable example is Professional Game Match Officials Ltd v HMRC (PGMOL).

The case ultimately reached the Supreme Court before being remitted to the First-tier Tribunal.

In its May 2026 decision, the First-tier Tribunal considered the individual match engagements using the established multifactorial approach to employment status.

The Tribunal emphasised that the assessment involves standing back and considering the relevant features of the relationship as a whole, rather than applying a simple checklist or presumption.

The Tribunal ultimately concluded that the individual match engagements were contracts for services rather than contracts of employment.

The case is useful because it demonstrates an important principle:

Employment status depends on the substance of the relationship and the relevant facts, not simply the title attached to the arrangement.

A Limited Company does not automatically make someone self-employed

This is one of the most common misconceptions surrounding contractor engagements.

A contractor having:

• their own Limited Company;

• their own company bank account;

• a company registration number;

• the ability to invoice;

• a written contract describing them as a contractor;

does not, by itself, determine employment status.

The underlying working relationship still matters.

Factors such as control, mutuality of obligation, personal service/substitution, financial risk, the way the work is performed and the wider circumstances can all be relevant.

This is why recruitment agencies should be cautious about treating IR35 as simply a box-ticking exercise.

So where does a specialist back-office partner fit in?

This is where Crystal Services Limited can help.

Crystal Services Limited is not an umbrella company.

We are a specialist back-office partner for recruitment agencies.

Our role is to support agencies that engage genuine contractors through their own Limited Companies by providing the administration and payment infrastructure around those engagements.

This can include:

Contractor onboarding

Helping gather and maintain the necessary contractor and assignment information.

Assignment administration

Keeping the relevant assignment information and documentation organised.

Contractor invoicing

Providing a structured process for contractor invoices to be submitted and processed.

Payment administration

Managing the administrative process involved in making payments to the contractor's Limited Company.

Records and communication

Providing a central point for contractor payment administration and maintaining appropriate records.

The recruitment agency remains the recruitment agency.

The client relationship remains with the recruitment agency.

The contractor remains responsible for operating their own Limited Company and meeting their own tax and company obligations.

And, importantly, Crystal Services Limited does not determine whether an engagement is inside or outside IR35 simply because we administer the payment.

Why agencies are looking at their back-office arrangements

Recruitment businesses are increasingly having to balance several competing priorities:

Recruit contractors quickly.

Keep clients happy.

Maintain appropriate compliance processes.

Deal with contractor queries.

Process invoices and payments.

Keep accurate records.

Understand where responsibility sits within the supply chain.

For an agency placing a relatively small number of contractors, this may be manageable internally.

For an agency placing significant numbers of Limited Company contractors, however, the administrative burden can quickly increase.

This is where outsourcing the back-office administration can make commercial sense.

The objective is simple

The objective isn't to create a complicated new layer between the recruitment agency and its contractors. It is to provide a specialist administration function behind the recruitment business.

The agency can continue concentrating on recruitment, client relationships and supplying talent.

Crystal Services Limited can take care of the contractor invoicing and payment administration that sits behind those engagements.

You find the contractor.

You manage the client.

We support the back office.

What recruitment agencies should be asking themselves

If your agency engages contractors through Limited Companies, it may be worth reviewing your current processes and asking:

1. Do we have a clear process for determining who is responsible for IR35?

2. Are we distinguishing properly between PSC engagements and umbrella arrangements?

3. Do we understand the responsibilities of each party in our supply chain?

4. Are contractor invoices and payments being processed consistently?

5. Are we maintaining appropriate contractor and assignment records?

6. Could our internal administration be handled more efficiently?

7. Would a specialist back-office partner reduce the administrative workload on our recruitment team?

These are not questions that have a single answer for every recruitment business.

The right structure will depend on the agency, the client, the contractor and the particular engagement.

A changing market requires a clear process

The recruitment market is not moving away from Limited Company contractors.

However, the regulatory environment around employment status, off-payroll working and labour supply chains is becoming increasingly important.

The changes introduced in April 2026 mean agencies using umbrella companies need to pay particular attention to PAYE compliance within their supply chains.

At the same time, IR35 remains an important consideration for engagements involving Personal Service Companies.

The safest approach is not to look for a one-size-fits-all answer.

It is to understand the particular engagement, establish where the relevant responsibilities sit and make sure the administration surrounding the engagement is properly managed.
