The Social Security Contributions and Benefits Act 1992 (Modification of Section 4A) Order 2026
This Statutory Instrument, made by HM Treasury with the concurrence of the Secretary of State, modifies section 4A of the Social Security Contributions and Benefits Act 1992 to align social security contribution rules with recent changes made to income tax legislation by the Finance Act 2026 concerning workers supplied through service companies and umbrella companies.
The Order primarily empowers the Treasury to introduce regulations holding certain persons jointly and severally liable with umbrella companies for contributions, and to treat payments made under deemed employment scenarios with 'purported umbrella companies' as earnings for contributions purposes.
Arguments For
Ensures consistency between income tax rules (ITEPA 2003, Chapter 11) and social security contribution liabilities concerning workers supplied via service companies or umbrella companies.
Establishes a mechanism for holding 'jointly liable persons' responsible for social security contributions, paralleling their existing joint liability for income tax under new legislation.
Clarifies the treatment of payments and benefits received by workers deemed to be employed by a 'purported umbrella company' for the purposes of calculating employer (secondary) contributions.
Arguments Against
Introduces complex new layers of joint and several liability, potentially increasing administrative burdens and compliance risks for individuals or entities caught by the 'jointly liable person' definition.
The reliance on future 'regulations' (under Article 2(a)) to fully define contribution recovery and treatment creates uncertainty regarding the practical application of these modifications until those regulations are issued.
Amendments target complex arrangements (umbrella companies), raising concerns that legislative intervention might be overly broad or might inadvertently impact legitimate, non-abusive supply chain working models.

The Social Security Contributions and Benefits Act 1992 (Modification of Section 4A) Order 2026
This heading identifies the instrument as a Statutory Instrument, numbered 2026 No. 341, falling under the category of Social Security law.
It formally names the legislation as the Order modifying Section 4A of the Social Security Contributions and Benefits Act 1992.
| Made - - - | 24th March 2026 | |------------------------|-------------------| | Laid before Parliament | 25th March 2026 | | Coming into force - | 26th March 2026 |
This table specifies the key procedural dates for the Order.
The instrument was formally made on March 24, 2026, presented to Parliament the following day, and became effective on March 26, 2026.
The provisions of Chapter 11 of Part 2 of the Income Tax (Earnings and Pensions) Act 2003( 1 ) were inserted by section 24 of the Finance Act 2026( 2 ).
It appears to the Treasury to be expedient, in consequence of those amendments, to modify the provisions of section 4A of the Social Security Contributions and Benefits Act 1992( 3 ) for the purpose of assimilating the law relating to income tax and the law relating to contributions under Part 1 of that Act.
Accordingly, the Treasury, with the concurrence of the Secretary of State, make this Order in exercise of the powers conferred by section 4A(9) of the Social Security Contributions and Benefits Act 1992.
The Treasury declares that recent amendments made by the Finance Act 2026, which inserted provisions into the Income Tax (Earnings and Pensions) Act 2003 (ITEPA 2003), require corresponding modifications to social security contribution rules under Section 4A. This change aims to assimilate (make consistent) the law covering income tax and National Insurance contributions.
The Treasury, agreeing with the relevant Secretary of State, executes this modification using powers granted under Section 4A(9) of the 1992 Act.
Citation and commencement
- This Order may be cited as the Social Security Contributions and Benefits Act 1992 (Modification of Section 4A) Order 2026 and comes into force on 26th March 2026.
Article 1 confirms the official title of this legislation.
It also reiterates that the Order officially came into effect on March 26, 2026.
Modification of the Social Security Contributions and Benefits Act 1992
- In section 4A of the Social Security Contributions and Benefits Act 1992 (earnings of workers supplied by service companies etc.)-
Article 2 outlines the specific changes being made to Section 4A of the Social Security Contributions and Benefits Act 1992, which deals with earnings when workers are provided through intermediary or service companies.
(a) after subsection (2B) insert-
'(2C) Regulations may also make provision-
(a) for a person ('a jointly liable person') to be jointly and severally liable for contributions payable by an umbrella company, including contributions payable as a result of provision made by virtue of paragraph (c), in respect of earnings paid to or for the benefit of an earner ('the worker') in circumstances where the jointly liable person is jointly and severally liable for amounts in respect of the employment of the worker as a result of Chapter 11 of Part 2 of ITEPA 2003,
(b) in connection with the recovery of those contributions from a jointly liable person, and
(c) for securing that, where an individual is treated for income tax purposes, as a result of section 61Z1 of ITEPA 2003, as holding an employment with a purported umbrella company, within the meaning of that section-
(i) payments or benefits of any specified description made or provided in connection with the performance by the individual of the services to which the deemed employment relates are treated for the purposes of the applicable provisions of this Act as earnings paid to the worker in respect of an employed earner's employment,
(ii) the individual is treated for those purposes, in relation to such payments or benefits, as employed in the employed earner's employment by the purported umbrella company, and
(iii) the purported umbrella company, whether or not fulfilling the conditions prescribed under section 1(6)(a) for secondary contributors, is treated for those purposes as the secondary contributor in respect of those payments or benefits.';
This inserts a new power (2C) allowing future regulations to address liabilities linked to income tax changes concerning umbrella companies.
It enables making a 'jointly liable person' equally responsible with the umbrella company for contributions related to a worker's earnings, if that person is already jointly liable for the income tax under ITEPA 2003.
Furthermore, it allows regulations to cover the recovery of these contributions.
Critically, it ensures that payments made under a deemed employment relationship with a 'purported' umbrella company (as defined in ITEPA 2003) are treated as earnings for contribution purposes, that the individual is treated as employed by that purported company, and that the purported company is treated as the entity responsible for paying employer (secondary) contributions.
- (b) in subsection (3)(g), for 'or the MSC' substitute ', the MSC or an umbrella company';
This modification updates subsection (3)(g) by expanding the list of entities mentioned, replacing the phrase 'or the MSC' with ', the MSC or an umbrella company'.
This integrates umbrella companies into the existing exemption or special rule structure related to subsection (3)(g).
(c) in subsection (4)-
(i) in paragraph (a), after 'intermediary' insert ', an umbrella company or a jointly liable person';
(ii) in paragraph (b)(i), for 'or the MSC' substitute ', the MSC, an umbrella company or a jointly liable person';
Subsections 4(a) and 4(b)(i) are amended to explicitly include 'an umbrella company' and 'a jointly liable person' in the scope of parties referenced within subsection (4).
This ensures that the definitions and exceptions apply correctly when dealing with these new entities in relation to earnings matters.
- (d) in subsection (6), at the appropriate place insert-
''umbrella company' has the same meaning as it has for the purposes of Chapter 11 of Part 2 of ITEPA 2003.'.
This inserts a definition for 'umbrella company' into subsection (6).
The definition adopted is the one already established and used within Chapter 11 of Part 2 of the Income Tax (Earnings and Pensions) Act 2003, ensuring definitional consistency across tax and contributions legislation.

EXPLANATORY NOTE
(This note is not part of this Order)
This Order modifies section 4A of the Social Security Contributions and Benefits Act 1992 ('SSCBA') in consequence of the insertion of Chapter 11 of Part 2 of the Income Tax (Earnings and Pensions) Act 2003 ('ITEPA 2003') by the Finance Act 2026.
The Explanatory Note clarifies that the Order's purpose is to adjust Section 4A of the SSCBA because the Finance Act 2026 introduced new rules in Chapter 11 of Part 2 of ITEPA 2003, which relate to employment income.
Article 2(a) inserts new paragraph (2C) and provides the Treasury with a power to treat a person as jointly and severally liable, with an umbrella company, for contributions payable in respect of earnings provided to or for the benefit of a worker, where that person is already jointly and severally liable in relation to income tax under Chapter 11 of Part 2 of ITEPA 2003.
It further permits regulations to make provision for the recovery of such contributions from a jointly liable person.
Article 2(a) establishes the framework where the Treasury can create regulations to make certain individuals or entities jointly and severally liable for social security contributions alongside an umbrella company.
This liability specifically arises when that person already shares income tax liability under the new ITEPA 2003 rules, and it includes mechanisms for recovering those contributions.
In addition, where an individual is treated for income tax purposes, by virtue of section 61Z1 of ITEPA 2003, as holding an employment with a purported umbrella company, regulations may secure that payments or benefits of a specified description are treated as earnings for contributions purposes, that the individual is regarded as employed in relation to those payments or benefits, and that the purported umbrella company is treated as the secondary contributor in respect of those payments or benefits.
The legislation also allows regulations to define how payments made under arrangements treated as employment by a 'purported umbrella company' (under specific income tax rules) are handled for National Insurance.
This ensures the payments count as earnings, the recipient is deemed employed, and the purported umbrella company is designated as the secondary (employer) contributor.
Paragraphs (b) and (c) of Article 2 make further modifications to subsections (3) and (4) of section 4A of the SSCBA to provide powers to disregard an employed earner's employment, in relation to relevant payments or benefits, and for the deduction of specified amounts, in respect of general expenses, and secondary Class 1 contributions.
Article 2(b) and (c) enact further technical changes to subsections (3) and (4) of the existing law.
These changes authorize powers related to ignoring certain employment statuses for contribution calculation purposes, and deal with the deduction of specific amounts pertaining to general expenses and secondary Class 1 contributions.
A Tax Information and Impact Note covering this instrument has been published on the website at: https://www.gov.uk/government/publications/paye-changes-for-the-umbrella-company-market.
The note directs readers to a published Tax Information and Impact Note available online. This document provides an assessment of the policy implications and financial impact resulting from these changes, especially concerning the payroll market for umbrella companies.
