Salaried Member Rules: Significant Influence Must Come from LLP Legal Rights, Not De Facto Clout

Introduction

In Commissioners for His Majesty's Revenue and Customs v BlueCrest Capital Management (UK) LLP [2026] UKSC 18, the United Kingdom Supreme Court considered the “salaried members legislation” introduced by the Finance Act 2014. The issue was whether certain members of an LLP should be treated, for income tax and national insurance purposes, as employees rather than self-employed partners.

HMRC had issued PAYE and NIC determinations against BlueCrest for the tax years 2014–2019, arguing that many of its individual members met the statutory conditions for treatment as salaried members. The appeal focused on Condition A, concerning whether remuneration was “disguised salary”, and Condition B, concerning whether a member had “significant influence” over the affairs of the LLP.

Summary of the Judgment

The Supreme Court dismissed BlueCrest’s appeal.

  • Condition A: The discretionary allocations paid to portfolio managers and desk heads were “disguised salary”. Although BlueCrest had a policy that total LLP profits could cap those allocations, the allocations were in substance calculated by reference to individual or desk performance, not by reference to the overall profits or losses of the LLP.
  • Condition B: “Significant influence” must derive from the legally enforceable mutual rights and duties of the LLP, its members, and the members inter se. Informal, de facto influence, personal status, strong performance, or profit contribution is not enough.
  • The First-tier Tribunal had applied the wrong test by treating operational and informal influence as sufficient. The issue of Condition B was therefore remitted to the First-tier Tribunal for reconsideration in light of the correct legal test.

Analysis

1. Precedents Cited

Statutory interpretation

The Supreme Court reaffirmed the orthodox approach to statutory interpretation, relying on R (Quintavalle) v Secretary of State for Health, R(O) v Secretary of State for the Home Department, and R (PACCAR Inc) v Competition Appeal Tribunal. The court emphasised that statutory words are the primary source of meaning, read in context and in light of legislative purpose.

The court also referred to R v Secretary of State for the Environment, Transport and the Regions, Ex p Spath Holme Ltd for the principle that citizens should be able to rely on the words of an Act of Parliament when arranging their affairs. This was especially important because the salaried members rules must be applied prospectively.

Seramco Ltd Superannuation Fund Trustees v Income Tax Comr was cited for the caution that ordinary statutory words should not be over-defined by judicial gloss.

Employment and partnership status

The court noted that the original legislative proposal had considered using common law employment status tests, such as those in Ready Mixed Concrete (South East) Ltd v Minister of Pensions and National Insurance and Professional Game Match Officials Ltd v Revenue and Customs Comrs. Parliament rejected that route and instead enacted the three statutory conditions.

Partnership status cases were central to the court’s reasoning. In Stekel v Ellice, the court had recognised that a “salaried partner” might still be a true partner depending on the substance of the relationship. The Supreme Court used that case to show that profit-sharing, capital contribution, and participation in management are indicators of partnership, but not individually decisive.

In Tiffin v Lester Aldridge LLP, members’ rights to participate in management were treated as a strong indicator of partner-like status. That case influenced the Supreme Court’s conclusion that Condition B is concerned with a member having a voice in the management or strategic affairs of the LLP, rather than merely operational importance.

For Condition A, the court referred to M Young Legal Associates Ltd v Zahid and Badeley v Consolidated Bank, together with partnership law principles, to explain that sharing overall firm profits is a classic indicator of partnership, whereas fixed or performance-based remuneration is more characteristic of employment.

The court also cited R v Board of Trade, Ex p St Martins Preserving Co Ltd when interpreting “affairs” broadly, while still holding that influence must be over the LLP’s affairs viewed as a whole.

2. Legal Reasoning

Condition B: source of significant influence

The key legal principle established is that influence counts for Condition B only if it derives from legally enforceable rights and duties. These may arise from:

  • the LLP agreement;
  • statute, including the Limited Liability Partnerships Act 2000 and default regulations;
  • contractual delegation under the LLP agreement;
  • formal roles traceable to the LLP’s constitutional arrangements; or
  • common law or equitable rights and duties, where applicable.

However, influence does not qualify merely because a member is commercially important, profitable, experienced, trusted, or persuasive. “Soft power” and informal clout are excluded.

Condition B: meaning of significant influence

The court held that “significant influence” does not require control, but it must have practical and commercial substance. The relevant influence will usually involve participation in managerial, strategic, or high-level decision-making concerning the LLP’s affairs as a whole.

Day-to-day operational decision-making in one part of the business, even a core or profitable part, is not normally enough. A portfolio manager’s ability to make investment decisions may affect the LLP’s profits, but that does not necessarily amount to significant influence over the LLP’s affairs.

Condition A: disguised salary

The Supreme Court rejected BlueCrest’s argument that a profit cap meant the discretionary allocations were varied by reference to overall LLP profits. The allocations were calculated by reference to the profits generated by the individual portfolio manager or desk, not by reference to the overall profits or losses of the LLP.

The court held that Condition A must be interpreted purposively. A merely theoretical or unused cap based on total LLP profits does not convert individual performance-based remuneration into genuine profit-sharing.

Impact of the Judgment

This decision is highly significant for LLPs, especially in financial services, asset management, professional services, and other sectors where members may be remunerated by reference to individual or team performance.

  • LLPs cannot rely on informal influence, seniority, or commercial importance to show that members fail Condition B.
  • The focus will be on the LLP agreement, statutory framework, and formal delegated authority.
  • Remuneration based on personal or desk profits is likely to be treated as disguised salary unless genuinely linked to the overall profits or losses of the LLP.
  • LLPs seeking partner-style tax treatment must ensure that members have real, legally grounded governance rights or strategic influence, not merely operational autonomy.

The judgment gives HMRC and taxpayers clearer guidance, but factual application will still depend on the particular LLP agreement and the formal rights conferred on members.

Complex Concepts Simplified

  • LLP: A limited liability partnership is a separate legal entity, but tax law often treats its members like partners.
  • Salaried member: A member of an LLP who is treated as an employee for tax and NIC purposes because the statutory conditions are met.
  • Disguised salary: Remuneration that looks more like employee pay than a genuine share of partnership profits.
  • Condition B: A test asking whether the member lacks significant influence over the LLP’s affairs. If the member has significant qualifying influence, Condition B is not met.
  • De facto influence: Practical influence not based on legal rights. The Supreme Court held that this does not count for Condition B.
  • Remitter: Sending the case back to a lower tribunal to apply the correct legal test.

Conclusion

The Supreme Court has clarified two important aspects of the salaried members legislation. First, significant influence must be grounded in legally enforceable LLP rights and duties, not informal power or commercial importance. Secondly, remuneration based on individual or desk performance remains disguised salary even if subject to an overall profit cap.

The decision narrows the ability of LLPs to argue that high-performing members are true partners for tax purposes merely because they are influential in practice. The decisive question is whether the member has a legally grounded voice in the LLP’s affairs as a whole.
