Most of the coverage of the April 2026 umbrella company rules got one detail wrong, and it is the detail that matters when you are sitting opposite a client.
The rules do not require your recruitment agency clients to operate PAYE for umbrella workers. The umbrella company is still the employer, still runs the payroll, still files the RTI submissions. What changed on 6 April 2026 is that when the umbrella does not pay HMRC what it owes, HMRC can now send that bill to your client instead – in full, with interest and penalties, and with no route for your client to argue they took reasonable care.
That distinction matters more than it looks. A client who believes this is a payroll administration change will pass it to their payroll manager. It is not a payroll change. It is a balance sheet exposure sitting inside contracts most of them have not re-read since the off-payroll reforms in 2021.
If you act for recruitment agencies, construction contractors, MSPs, or any business that engages temporary labour through a third party, this is a conversation worth having before the next year-end file lands on your desk.
The position in short
- What: Joint and several liability for unpaid PAYE income tax and Class 1 NIC where an umbrella company sits in a labour supply chain.
- Where: New Chapter 11, Part 2 of ITEPA 2003 (sections 61Y to 61Z2), inserted by Finance Act 2026, which received Royal Assent on 18 March 2026. Equivalent NIC provisions come through regulations under section 4A of the Social Security Contributions and Benefits Act 1992.
- When: Payments made to umbrella company workers on or after 6 April 2026.
- Who pays: The agency holding the contract with the end client. Where there is no agency, the end client.
- Defences available: None. No reasonable care defence, no knowledge test, no carve-out for businesses that carried out thorough checks.
What actually changed on 6 April 2026 – and what did not
When HMRC first announced this in October 2024, the stated intention was to move the responsibility for accounting for PAYE from the umbrella company to the agency. A good deal of client-facing material still reflects that original announcement, and some of your clients will have been briefed on it. It is worth correcting, because the final design is different and the difference changes what your clients need to do.
The legislation as enacted leaves the umbrella company in place as the employer. It continues to calculate PAYE, submit RTI, and pay HMRC. Nothing about the worker’s payslip changes. What the legislation adds is a second party who is liable for the same debt at the same time.
That is what joint and several liability means in practice: HMRC can pursue either party for the whole amount. It does not have to establish that the umbrella failed first, does not have to attempt collection from the umbrella first, and does not have to apportion the debt between the parties. HMRC’s own guidance is direct about this – it does not matter which party pays or how much each pays, provided the amount is paid in full.
HMRC’s manual does note there may be circumstances where it is appropriate to pursue the umbrella company instead. That is administrative discretion, not a protection. No client should build a position around it.
What falls within the liability: PAYE income tax and Class 1 NIC. HMRC’s policy paper also refers to the Apprenticeship Levy. Interest and penalties follow the underlying debt.
The scale of the problem HMRC is addressing gives some sense of why the rule is drawn this tightly. In its October 2024 policy paper, HMRC estimated around 700,000 workers were engaged through umbrella companies in 2022/23, that more than a third of them were engaged by non-compliant operators, and that the cost to the Exchequer was at least £500 million a year.
How the liability cascades: identifying the “relevant party”
Section 61Z sets out who carries the liability alongside the umbrella. HMRC’s Employment Status Manual (ESM2420) works through the scenarios. This is the reference table your clients need:
| Structure of the supply chain | Jointly and severally liable with the umbrella |
| End client contracts directly with the umbrella, no agency involved | The end client |
| One agency between client and umbrella | That agency |
| Several agencies (tiered supply, MSP or neutral vendor model) | The agency that holds the contract with the end client — not the agency that engaged the umbrella |
| The agency contracting with the client is connected to the umbrella (s.993 ITA 2007) | The end client, alongside the umbrella and that agency |
| The agency and the client are connected | Normal rule applies — the agency contracting with the client |
| Worker placed with a UK client by or through a non-UK resident agency | The end client |
| Agency and client both non-UK resident, other parties in the chain | The UK agency closest to the client |
Three points to draw out for clients.
Tiered supply is where the exposure concentrates. The liability attaches to the agency closest to the end client, not the agency that selected the umbrella. A top-tier agency or MSP that subcontracts fulfilment to second-tier suppliers now carries liability for umbrella companies it has never assessed, may never have heard of, and has no contractual relationship with. If your client operates a second-tier model, that is the single largest item on their risk register.
The definition is functional, not nominal. ESM2415 makes clear the measure applies to intermediaries that perform the legal obligations of an employer for tax purposes, whether or not they describe themselves as an umbrella company. Any third party that employs the worker, carries on a business of supplying labour, and in which the worker does not hold a material interest is caught. What it calls itself is irrelevant.
“Purported” umbrella companies are caught too. Section 61Z1 deals with arrangements structured to look like umbrella employment without meeting the statutory definition – including where a worker has been given a nominal material interest in the vehicle. Material interest means broadly more than 5% of share capital, distributions or winding-up assets, and any interest arising from arrangements with a main purpose of escaping joint and several liability is disregarded. The drafting anticipates mini-umbrella structures and offshore vehicles.
Why due diligence does not give your client a defence
This is the part clients find hardest to accept, and it is worth being blunt about it.
There is no statutory defence in Chapter 11. The regime operates on a strict liability basis. It does not matter that your client:
- carried out due diligence before appointing the umbrella
- paid the umbrella in full, including every penny of the PAYE and NIC element
- held a current accreditation certificate on file
- had no knowledge of, and no reason to suspect, any failure
- acted entirely in good faith throughout
If the umbrella did not pay, and your client is the relevant party, your client owes the money.
Accreditation is not a shield
FCSA accreditation, Professional Passport approval and similar schemes are genuinely useful. They are also point-in-time assessments carried out by private bodies. An accreditation tells you an umbrella met a standard on the date it was audited. It tells you nothing about whether the umbrella remitted last month’s PAYE, and it confers no statutory protection whatsoever.
There is no HMRC-approved list
This one comes up constantly and is worth stating plainly to clients: HMRC does not approve, accredit, endorse or maintain a list of umbrella companies. If a supplier claims to be “HMRC approved,” or a client believes they selected from an official list, the premise is false. No such list exists.
Indemnities are only as good as the counterparty
Most umbrella contracts contain a tax indemnity. It is worth having. It is not protection.
Consider the sequence. The umbrella fails to pay over PAYE. HMRC assesses your client. Your client pays. Your client then seeks to enforce the indemnity against a company that has just demonstrated it cannot or will not meet a tax liability – and which, in the typical case, has already been dissolved and its worker population migrated to a newly incorporated vehicle with different directors. An indemnity is a contractual promise, recoverable through civil proceedings, worth whatever the counterparty is worth on the day you call on it.
So why do due diligence at all?
Because it is the only thing that changes the probability of a loss, even though it cannot change the consequence of one. Four reasons that hold up:
- It determines which umbrellas are in the chain. Supplier selection is the actual control. Everything else is documentation.
- It supports civil recovery. Evidence of what was represented, by whom, and when, is what makes a claim against the umbrella and its directors viable rather than theoretical.
- It supports the commercial and insurance position. Brokers, end clients, and prospective buyers all ask. A client with no answer prices worse.
- It is a governance obligation. Directors of a business carrying an unquantified, uninsured, strict-liability tax exposure need to be able to show the board considered it. That is a directors’ duties question before it is a tax one.
The framing to give clients: due diligence no longer buys you a defence. It buys you a smaller chance of ever needing one.
The supply chain mapping exercise every affected client needs
This is the work. It is not complicated, but it is detailed, and in our experience it is almost never possible to complete from the accounting records alone. Expect to need the contracts.
Step 1 – Establish whether an umbrella is in the chain at all. A surprising number of clients do not know. The indicators: workers receiving payslips from a company that is neither the client nor the agency; an “assignment rate” or “uplifted rate” in the contract rather than a pay rate; a margin line on the worker’s payslip; employment costs deducted before gross pay is calculated.
Step 2 – Map contractually, not operationally. The liability follows the contract with the end client. It does not follow the flow of funds, the placing agency, or the entity that manages the worker day to day. Ask for the contract chain, not the process diagram.
Step 3 – Build the umbrella register. For every umbrella identified: company number, date of incorporation, registered office, current and former directors, filing history and any late filings, PAYE scheme reference, VAT registration, accreditation status and audit date, and the bank account pay is routed from.
Step 4 – Reconcile a sample of assignment rate to payslip. Take three or four workers. Start with the assignment rate. Deduct employer NIC, the Apprenticeship Levy where it applies, employer pension contributions, holiday pay accrual and the umbrella’s stated margin. What is left should be gross pay. If the worker’s take-home is higher than that arithmetic supports, something is being paid outside PAYE. That single test catches most of what accreditation misses.
Step 5 – Test for tiering. Ask each direct supplier, in writing, whether any part of the supply is subcontracted and to whom. Put the obligation to disclose onward supply into the contract at the next renewal.
Step 6 – Set a monitoring cycle. A point-in-time check does not survive a phoenix. Quarterly at minimum: re-check filing history, director changes, and any change to bank details or trading name.
Red flags worth naming for clients
- Advertised take-home percentages higher than the arithmetic in Step 4 supports
- Recently incorporated companies with a large and rapidly acquired worker population
- Directors with a history of dissolved payroll or employment intermediary companies
- Pay routed from a company other than the one named in the contract
- Any element of pay described as an advance, loan, grant, annuity, credit facility or non-taxable allowance
- Reluctance to provide a PAYE reference, or to evidence RTI submissions
- Frequent changes of trading name, registered office or bank details
The case for moving workers onto agency or in-house payroll
The objection you will hear first is cost: “We cannot bring 400 workers onto our own payroll, employer NIC alone would sink us.”
That objection misreads where those costs currently sit, and it is worth taking apart carefully because it usually decides the conversation.
In a standard umbrella arrangement, the employment costs are already being funded out of the assignment rate. Employer NIC at 15% on earnings above the £5,000 secondary threshold, the Apprenticeship Levy at 0.5% where the paybill exceeds £3 million, employer pension contributions, holiday pay accrual, and the umbrella’s own margin all come out of that rate before the worker’s gross pay is calculated. Your client is paying every one of those costs today. They simply appear as a single supplier invoice rather than as payroll lines.
Moving the worker onto agency payroll does not create those costs. It changes who administers them, and it removes the umbrella’s margin from the equation.
What genuinely gets added:
- Payroll processing and RTI submission, typically on a weekly cycle
- Auto-enrolment assessment and pension administration on variable pay
- Holiday accrual and statutory payment administration on irregular hours
- Direct employment liabilities – unfair dismissal after the qualifying period, redundancy, tribunal exposure
- Working capital, since your client pays the worker before the client pays the invoice
What gets removed:
- The joint and several liability exposure entirely
- The umbrella’s margin
- The ongoing due diligence and monitoring burden
- The reputational exposure of a worker on a client site turning out to be inside a disguised remuneration scheme
When umbrella use still makes sense: high-volume, short-assignment populations spread across multiple agencies; workers who value continuity of employment between assignments; situations where the end client mandates it. Umbrella use remains entirely lawful, and a great many operators are fully compliant. The honest position is that this is a risk-and-cost decision, not a compliance-forced one – but your client is now underwriting somebody else’s compliance with their own balance sheet, and that should be priced.
Practical middle grounds for clients not ready to move everyone:
- Cut the panel to a small number of umbrellas the business can realistically monitor
- Contract directly with the umbrella and prohibit onward subcontracting
- Move the longest-duration, highest-value assignments first – they carry the largest per-worker liability
- Where an end client insists on an umbrella, price the retained risk into the rate

Construction clients: how this sits alongside CIS and IR35
Construction is the sector where all three regimes meet on the same site, often on the same invoice, and it is where we see the most confusion.
They do not overlap the way people assume:
- CIS applies to payments to self-employed subcontractors for construction operations.
- Umbrella joint and several liability applies to workers employed by an umbrella. Those are employees on PAYE, entirely outside CIS.
- Off-payroll working (IR35) applies to workers supplying through their own intermediary, usually a personal service company.
A single site can carry all three. A single labour supplier can present all three under one contract and one invoice – and that invoice will not tell you which worker sits where. The mapping in construction has to run worker by worker, not contract by contract.
The 2021 decision that now needs revisiting
After the April 2021 off-payroll reforms, a large number of construction end clients pushed contractors off PSCs and onto umbrella companies. It removed the status determination burden and the associated liability. It was a rational response at the time.
What it did was substitute one exposure for another, and the second exposure has now been priced. Clients who made that switch in 2021 should look at it again. The reason they chose umbrella has not disappeared – but the cost of that choice has changed materially.
The CIS changes that landed the same day
Three CIS changes also took effect on 6 April 2026, following the Autumn Budget 2025 consultation:
- Monthly nil returns are mandatory again. Contractors must file a CIS300 for every tax month, including months with no subcontractor payments, unless an inactivity request has been submitted to HMRC in advance. The deadline is the 19th of the month, and the full late filing penalty regime applies – a £100 automatic penalty from day one. The ability to routinely appeal nil-return penalties has gone.
- Public body payments are outside CIS. New Regulation 24ZA formalises the previous extra-statutory concession. Payments to local authorities and certain public bodies, including housing associations, are now fully exempt.
- New CIS fraud measures. HMRC can pursue parties in the supply chain who should have known about fraudulent transactions, not only those who acted deliberately. Gross payment status is the pressure point.
Read those together, and the picture for a construction client is stark. On the self-employed side, a “should have known” test. On the umbrella side, no knowledge test at all. The umbrella side is the harder of the two to manage.
One clarification worth giving construction clients: a genuine CIS self-employment arrangement does not create an umbrella company, because there is no employment. But if HMRC successfully challenges status and recharacterises the arrangement, the client can find itself in a regime it never planned for. Employment status remains the foundation everything else sits on.
We run monthly CIS returns and subcontractor verification and support practices across the wider construction client base, including reverse charge VAT and project-based accounts.
What this means for your practice
Which clients to review first: recruitment agencies of any size; MSPs and neutral vendors; construction contractors, housebuilders and civils firms; care, health and education providers; and any client with “labour supplier,” “contract labour” or “agency staff” as a material line in the P&L.
The three questions to open with:
- Is there an umbrella company anywhere in your labour supply chain?
- If so, do you hold the contract with the end client?
- Can you produce today a current list of every umbrella in that chain?
A client who cannot answer the third question has an exposure they cannot size. That is the conversation.
The reporting angle. For clients with material exposure, this needs to be considered as a contingent liability at year-end. Where the supply chain is tiered or includes umbrellas the client cannot evidence checks on, raise it with the audit team early rather than at file review. It is a far easier conversation in September than in the week before signing.
The fee opportunity is real. Supply chain mapping, an ongoing monitoring service, payroll transition projects, and the recurring payroll work that follows – this is advisory work with a clear trigger and a client base that has just been given a reason to buy it.
Where the capacity comes from
Two distinct problems land at once.
The first is advisory: mapping, contract review, the client conversations. That is partner and manager time, and it is time-sensitive because the liability is already running.
The second is volume. If clients move workers onto their own payroll, your payroll function absorbs a step change – usually mid-year, usually at short notice, and usually in weekly cycles with variable timesheet data. Weekly high-churn payroll is a different discipline from monthly salaried payroll: auto-enrolment assessment on fluctuating earnings, holiday accrual on irregular hours, starters and leavers every cycle, and RTI on time regardless.
That second problem is the one an outsourced payroll team is built for. It frees the partner time for the first.

Frequently asked questions
Do recruitment agencies have to operate PAYE for umbrella workers from April 2026?
No. This is the most common misunderstanding. The umbrella company remains the employer and continues to operate PAYE and file RTI. The agency becomes jointly and severally liable if the umbrella fails to pay HMRC.
Is there an HMRC-approved list of umbrella companies?
No. HMRC does not approve, accredit or endorse umbrella companies, and maintains no such list. Accreditation schemes such as FCSA and Professional Passport are run by private bodies and carry no statutory weight.
Does FCSA accreditation protect an agency from liability?
No. It is useful evidence of supplier selection and a reasonable input to due diligence, but it provides no defence under Chapter 11 ITEPA 2003.
Does a tax indemnity in the umbrella contract protect my client?
Only commercially, and only if the umbrella is solvent and traceable when the indemnity is called on. It gives your client a civil claim; it does not stop HMRC recovering from them first.
Who is liable where several agencies sit in the chain?
The agency that holds the contract with the end client — not the agency that engaged the umbrella. Tiered and MSP models concentrate liability at the top.
What if the agency is based overseas?
Where a worker is placed with a UK client by or through a non-UK resident agency, the end client is jointly and severally liable alongside the umbrella. Where the agency and client are both non-UK resident and other parties sit in the chain, the UK agency closest to the client carries it.
Does this affect CIS subcontractors?
Not directly. CIS applies to self-employed subcontractors; umbrella joint and several liability applies to umbrella employees. The practical issue in construction is that a single labour supplier often provides both, under one invoice.
What happens if the umbrella has already been liquidated?
The liability still sits with the relevant party. That outcome is the purpose of the rule, not a gap in it.
