Supreme Court redraws line between member and employee in LLPs

The UK Supreme Court's recent judgment in *HMRC v BlueCrest Capital Management (UK) LLP* [2026] UKSC 18 has significantly clarified the application of the "salaried member rules" for Limited Liability Partnerships (LLPs), particularly concerning the distinction between a member and an employee for tax purposes. The ruling narrows the interpretation of "significant influence" (Condition B) required for a member to avoid being taxed as an employee, asserting that such influence must stem from legally enforceable rights and duties within the LLP agreement, rather than mere de facto operational involvement. Furthermore, the Court reinforced HMRC's stance on "disguised salary" (Condition A), impacting how remuneration structures are assessed. This decision necessitates a critical review of LLP structuring, member agreements, and remuneration models for professional services firms to mitigate increased tax liabilities and compliance risks.

The landscape governing the status of individuals within Limited Liability Partnerships (LLPs) in Great Britain has once again been reshaped by a pivotal Supreme Court decision. Last week, the Supreme Court handed down its long-awaited judgment in *HMRC v BlueCrest Capital Management (UK) LLP* [2026] UKSC 18, a ruling that carries profound implications for professional services firms, including asset managers, law firms, accountancy practices, and consultancies operating as LLPs. [5, 11, 16, 18, 21]

This landmark decision specifically addresses the "salaried member rules" under tax legislation, fundamentally redrawing the line between an LLP member and an individual treated as an employee for income tax and National Insurance Contributions (NICs) purposes. [5, 11, 16, 18, 21] While the employment law distinction between a "worker" and an "employee" for LLP members was clarified over a decade ago, this latest ruling sharpens the focus on the tax implications of member status, compelling LLPs to scrutinise their internal governance and remuneration structures to ensure compliance and avoid unintended tax liabilities. [6, 10, 13]

The Supreme Court's pronouncements, particularly on the interpretation of "significant influence" and "disguised salary," will necessitate a comprehensive re-evaluation of existing LLP agreements and operational realities. This article delves into the background of LLP member status, analyses the core tenets of the *BlueCrest* judgment, and outlines the critical implications for practitioners advising or operating within LLPs.

Limited Liability Partnerships, established under the Limited Liability Partnerships Act 2000 (LLPA 2000), offer a hybrid legal structure combining the organisational flexibility of a partnership with the limited liability of a company. [19, 22, 25] Unlike traditional partnerships, an LLP is a separate legal entity, capable of employing staff and entering into contracts. [4, 24] However, for tax purposes, LLP members are generally treated as self-employed partners, with profits allocated to them subject to self-assessment rather than Pay As You Earn (PAYE) and employer NICs. [2, 19, 21]

To counter arrangements where individuals who are, in substance, employees are structured as LLP members solely for tax advantages, HMRC introduced the "salaried member rules" in 2014, codified in the Income Tax (Trading and Other Income) Act 2005 (ITTOIA 2005). [2, 19] These rules stipulate that an LLP member will be treated as an employee for income tax and NICs purposes if three conditions (Conditions A, B, and C) are all met. [5, 11, 16, 18, 19, 21] Condition A relates to whether at least 80% of the member's remuneration is a "disguised salary" (fixed or not truly variable by reference to overall LLP profits). [5, 11, 16, 18, 21] Condition B concerns whether the member lacks "significant influence" over the affairs of the LLP. [5, 11, 16, 18, 21] Condition C examines whether the member's capital contribution is less than 25% of their disguised salary. [5, 11, 16, 18, 21]

It is crucial to distinguish these tax-focused "salaried member rules" from the broader employment law concept of "worker" status. The landmark Supreme Court case of *Clyde & Co LLP v Bates van Winkelhof* [2014] UKSC 32 established that an LLP member, while not an "employee" in the traditional sense, could still qualify as a "worker" under Section 230(3)(b) of the Employment Rights Act 1996 (ERA 1996). [6, 9, 10, 13] This classification grants members access to certain employment rights, such as whistleblowing protection, national minimum wage, and paid annual leave, without necessarily being deemed an employee for all purposes. [10, 13, 17, 20] The *BlueCrest* decision, however, focuses squarely on the tax implications of the member-employee distinction, adding another layer of complexity to LLP structuring.

The Supreme Court's judgment in *HMRC v BlueCrest Capital Management (UK) LLP* [2026] UKSC 18 provides critical clarification on Conditions A and B of the salaried member rules, significantly impacting how LLPs assess their members' tax status. [5, 11, 16, 18, 21] The case primarily concerned an investment management LLP where HMRC argued that many members should be treated as employees for tax purposes. [5, 16]

Regarding Condition B, which assesses whether a member lacks "significant influence" over the LLP's affairs, the Supreme Court definitively ruled that such influence must derive from *legally enforceable rights and duties* arising under the LLP agreement or other binding governance instruments. [5, 11, 16, 18] Crucially, the Court rejected the notion that *de facto* influence, however real in practice (e.g., through commercial importance or high-value investment decisions), is sufficient to satisfy this condition if it is not legally enshrined. [5, 11, 16, 18] This overturns previous tribunal approaches that considered realistic or practical influence. The Court further clarified that "significant influence" requires high-level or strategic decision-making or influence over the LLP's affairs as a whole, rather than day-to-day operational responsibility. [5, 11, 16]

On Condition A, concerning "disguised salary," the Supreme Court confirmed HMRC's position that remuneration calculated by reference to an individual's own portfolio or desk profits can still fall within this test, even if a firm-wide profit figure acts as a backstop cap. [11, 18, 21] The Court emphasised that a cap merely limiting downside exposure does not create the substantive link to overall LLP profits necessary to avoid characterisation as "disguised salary." [11, 21] The purpose of Condition A is to distinguish between typical partner remuneration (linked to overall profits) and typical employee remuneration (fixed or not substantially variable with overall profits). [21]

This ruling effectively "redraws the line" by narrowing the scope for LLPs to argue that members possess sufficient influence or profit-sharing arrangements to avoid being classified as salaried members for tax purposes. [11, 16, 18, 21] The emphasis on legally enforceable rights and strategic influence, rather than practical operational involvement, represents a stricter interpretation that will likely lead to more members being caught by the salaried member rules. This contrasts with the *Bates van Winkelhof* decision, which broadened the definition of "worker" for employment rights by focusing on the economic reality of personal service, irrespective of formal titles or subordination. [6, 10, 13] While *Bates van Winkelhof* expanded protections for LLP members as workers, *BlueCrest* tightens the criteria for their tax treatment as self-employed, highlighting the distinct and often divergent tests applied across different legal regimes.

The Supreme Court's judgment in *HMRC v BlueCrest Capital Management (UK) LLP* [2026] UKSC 18 is a wake-up call for all LLPs, particularly those in the professional services sector. Practitioners must immediately review their LLP agreements and governance frameworks to ensure that the documented rights and duties of members align with the intended tax treatment. Reliance on informal or de facto influence will no longer suffice to demonstrate "significant influence" under Condition B of the salaried member rules. [5, 11, 16, 18]

LLPs should proactively audit their existing membership categories and remuneration structures, considering whether amendments to LLP agreements are needed to embed genuine, legally enforceable strategic influence for members and to ensure remuneration is genuinely linked to overall firm profitability, not merely individual performance subject to a firm-wide cap. [11, 18, 21] Failure to do so could result in significant retrospective and ongoing employer NICs liabilities and PAYE obligations, transforming what was intended as a tax-efficient structure into a costly compliance burden. This decision underscores the critical importance of meticulous legal drafting and a clear understanding of the nuanced distinctions between member, worker, and employee status across both employment and tax law.
