The Social Security Contributions (Umbrella Companies) Regulations 2026
Established joint liability for National Insurance payments between umbrella companies, recruitment agencies, and clients to prevent tax avoidance in labour supply chains.
These regulations establish joint and several liability for National Insurance contributions (NICs) within labour supply chains involving umbrella companies.
They direct that recruitment agencies or end-clients must pay unpaid Class 1 NICs if the umbrella company employing a worker fails to do so.
The rules apply to 'relevant parties'—typically the agency closest to the client in the contractual chain—and include provisions to prevent avoidance through 'purported' umbrella companies or fraudulent documentation.
The regulations affect recruitment businesses, umbrella companies, and various clients across the United Kingdom who engage workers via intermediaries.
Arguments For
The regulations aim to secure the payment of National Insurance contributions within labour supply chains by making agencies and clients responsible for defaults by umbrella companies.
The document states that these measures are necessary following the insertion of Chapter 11 into the Income Tax (Earnings and Pensions) Act 2003 by the Finance Act 2026.
Proponents within the government framing suggest the rules will prevent tax avoidance by defining 'purported' umbrella companies and ensuring a liable entity exists within the UK jurisdiction.
The explanatory note indicates the regulations provide HMRC with clear powers to determine when liability conditions are met, improving enforcement capabilities.
Arguments Against
Legal scholars may question the complexity of the 'relevant party' definitions, which could lead to disputes over which entity in a multi-layered supply chain is liable.
Recruitment agencies have expressed concerns regarding the significant financial risk of being held liable for the tax defaults of third-party umbrella companies they do not control.
Affected businesses might argue that the 'reasonable to suppose' tests regarding the status of a 'purported umbrella company' introduce subjectivity and commercial uncertainty.
Implementation difficulties may arise for small agencies required to perform advanced due diligence on the employment status and tax compliance of every umbrella company in their chain.

Interpretation
- -(1) In these Regulations-
'arrangements' include any agreement, understanding, scheme, transaction or series of transactions (whether or not legally enforceable);
'the client' has the meaning given in regulation 3(1)(a);
'the deemed employer provisions' means-
- (a) paragraph 2 of Part 1 of Schedule 1 to the Social Security (Categorisation of Earners) Regulations 1978,
- (b) paragraph 2 of Part 1 of Schedule 1 to the Social Security (Categorisation of Earners) (Northern Ireland) Regulations 1978,

- (d) regulations 6 and 18 of the Social Security Contributions (Intermediaries) (Northern Ireland) Regulations 2000,
- (e) regulations 3 and 4 of the Social Security Contributions (Managed Service Companies) Regulations 2007, and
- (f) regulations 3 and 4 of the Social Security Contributions (Limited Liability Partnership) Regulations 2014;
'material interest' has the meaning given by section 61Y(5) of ITEPA 2003;
'purported umbrella company' has the meaning given by regulation 5(2) to (4), as the case may be;
'qualifying umbrella company payment' means a payment made in respect of the employment of a worker as an employed earner to the extent that it is not in respect of the provision of services to a person other than the client;
'relevant party' has the meaning given by regulation 4;

'worker' has the meaning given in regulation 3(1)(a).
(2) In these Regulations references to an individual being employed as an employed earner do not include the individual being treated as an employed earner as a result of any of the deemed employer provisions, and 'employment' and 'employer', in relation to an employed earner, are to be construed accordingly.
(3) In the application of regulations 3 to 5 to Northern Ireland a reference to an enactment or instrument made under an enactment applying to Great Britain is to be read as a reference to the corresponding enactment or instrument made under an enactment applying in Northern Ireland.
This section defines the core legal terms used throughout the document to ensure consistent application.
It excludes individuals who are only 'treated' as employees under specific anti-avoidance laws (like IR35 or Managed Service Company rules) from the primary definition of an employed earner for these specific regulations.
It also ensures that the regulations apply equally across Great Britain and Northern Ireland by cross-referencing equivalent regional legislation.
Umbrella companies: joint and several liability
- -(1) Paragraph (2) applies if-
(a) an individual ('the worker') personally provides services, or enters into arrangements with a view to personally providing services, to another person ('the client'),
(b) the worker is employed as an employed earner by a third person (the 'umbrella company')
(i) that carries on a business, whether or not with a view to profit and whether or not in conjunction with any other business, of supplying labour, and
(ii) that is not a company in which the worker has a material interest, and
(c) the umbrella company arrangements conditions are met.
(2) Each relevant party-
- (a) is, along with the umbrella company, jointly and severally liable to pay any amount payable, in accordance with sections 6, 10 and 10A of and paragraph 3 of Schedule 1 to the SSCBA, by the umbrella company in relation to a qualifying umbrella company payment, but
- (b) is not to be treated as the secondary contributor for the purposes of section 7 of the SSCBA.
(3) The umbrella company arrangements conditions are that-
(a) there is a contract between the umbrella company and-
(i) the client, or
(ii) another person,
(b) under or in consequence of the contract-
(i) the services are provided, or
(ii) the umbrella company is paid, or otherwise provided with consideration, for the services, and
(c) if the contract is not between the umbrella company and the client-
- (i) there is a contract between the client and another person, and
- (ii) the provision of the services or of payment or other consideration for the services is also a consequence of that other contract, whether directly or as a result of a series of contracts involving other persons.
(4) Any issue whether the circumstances are such as are mentioned in paragraph (1) is an issue relating to contributions that is prescribed for the purposes of section 8(1)(m) of the Social Security Contributions (Transfer of Functions, etc.) Act 1999 (decision by officers of Board).
This provision creates a shared legal responsibility for National Insurance debts between an umbrella company and other parties in the recruitment chain.
If an umbrella company fails to pay the required contributions for a worker it employs, the 'relevant party' becomes equally liable for those costs.
It clarifies that while these parties are liable for the debt, they do not take on the formal legal status of the 'secondary contributor' (the official employer for tax purposes).
The section also authorizes HMRC officers to make formal decisions on whether these liability conditions have been met.
Relevant Parties
- -(1) If the contract referred to in regulation 3(3)(a) is between the umbrella company and a person other than the client, the person referred to in regulation 3(3)(c)(i) is a relevant party.
(2) The client is a relevant party if-
- (a) the contract referred to in regulation 3(3)(a) is between the umbrella company and the client, or
- (b) the person referred to in regulation 3(3)(c)(i)-
- (i) is connected, within the meaning of section 993 of the Income Tax Act 2007 (meaning of 'connected' persons), with the umbrella company, or
- (ii) is not resident in the United Kingdom.
(3) In a case where-
- (a) both the client and the person referred to in paragraph (3)(c)(i) of regulation 3 are not resident in the United Kingdom,
- (b) the provision of the services or payment or other consideration for the services is a consequence of a series of contracts involving other persons, other than the worker, and
- (c) at least one of those persons is resident in the United Kingdom,
the person who is resident in the United Kingdom and is closest, by reference to that series of contracts, to the client is a relevant party.
This section identifies which specific entities are a 'relevant party' and thus liable for unpaid National Insurance.
Generally, this is the recruitment agency that has the direct contract with the client or the next person in the chain if the direct contractor is outside the UK or linked to the umbrella company.
If all primary parties are based abroad, the liability falls on the UK-resident business that is contractually closest to the client.
Purported umbrella companies
- -(1) Paragraph (5) applies if any of the following cases applies. (2) Case 1 [summarised]: a person gives the impression of being an employer or is assumed to be an employer by others, but is not actually the employer. (3) Case 2 [summarised]: an individual is treated as an employee via specific agency tax rules but the services provided weren't part of a standard recruitment finding fee. (4) Case 3 [summarised]: a company where the worker has an interest participates in arrangements where it's assumed their pay is employment income, but it isn't paid as such. (5) If this paragraph applies- (a) the individual is treated as employed by the purported umbrella company; (b) remuneration is treated as earnings; (c) the purported umbrella company is the secondary contributor; (d) if money is paid elsewhere, the company is treated as paying it to the worker; and (f) joint liability applies. (10) Each person involved is jointly and severally liable. (12) HMRC decides if these circumstances exist.
This section targets schemes that mimic umbrella companies to avoid tax.
It defines three 'Cases' where a business can be classified as a 'purported umbrella company,' such as when it falsely presents itself as an employer or uses complex structures to avoid paying wages as employment income.
When these cases apply, the individual is legally treated as an employee, and all parties in the chain become jointly and severally liable for the resulting National Insurance contributions.
Amendment of the Social Security (Categorisations of Earners) Regulations 1978
- -(1) The Social Security (Categorisation of Earners) Regulations 1978 are amended as follows. (2) In regulation 1(2) insert definition of 'foreign purported umbrella company'. (3) In Schedule 3, include contracts between foreign purported companies and end clients or UK agencies. Designate the end client or UK agency as the person responsible for National Insurance.
This regulation updates existing 1978 rules to address umbrella companies based outside of Great Britain.
It ensures that if a foreign entity acts as a purported umbrella company, the responsibility for National Insurance is transferred to the UK-based agency or the client receiving the services.
This change is designed to ensure there is always a domestic entity from which HMRC can collect contributions.
Amendment of the Social Security (Categorisation of Earners) Regulations (Northern Ireland) 1978
- [Content mirrors Regulation 6 but applies specifically to the Northern Ireland 1978 Regulations to ensure regional parity.]
This section performs the same function as Regulation 6, but for the Northern Ireland legal system.
It ensures that agencies or clients in Northern Ireland are responsible for National Insurance when using foreign purported umbrella companies.
Amendment of the Social Security Contributions (Intermediaries) Regulations 2000 / (Northern Ireland) 2000
- & 9. In regulation 22... after paragraph (4) insert- '(4A) But where the fraudulent documentation condition would... be met as a result of the provision of a fraudulent document intended to constitute evidence that regulation 3... applies... that condition is to be treated as not met.'
These sections amend the 'Intermediaries' (IR35) regulations for both Great Britain and Northern Ireland.
They prevent parties from using fraudulent documents as a defense to trigger umbrella company liability rules as a way to circumvent other tax obligations.
Essentially, if a document is faked to make a situation look like a standard umbrella arrangement covered by these new 2026 rules, that fake evidence will be disregarded.
