Supreme Court clarifies LLP salaried member rules in landmark BlueCrest decision

Sean Drury and Mark Eade look at the landmark BlueCrest decision and the subsequent impact it will have on LLP salaried member rules

30 June 2026 | Author: Sean Drury, Mark Eade

The landmark BlueCrest decision will impact LLP salaried member rules which, for many LLPs may not simply be a technical tax issue

Why is it relevant?

The long-running BlueCrest litigation has finally reached the Supreme Court, resulting in what is arguably the most significant judgment on the LLP salaried member rules (“SMR”) since they were introduced in 2014.

The decision provides important clarification on when LLP members will be treated as genuine self-employed members and when they may instead be treated as employees. In doing so, the decision could trigger a wave of reviews by LLPs across a wide range of sectors, including professional services, financial services, investment management and private equity.

For many LLPs, the decision may not simply be a technical tax issue. It has the potential to expose existing structures to PAYE and National Insurance liabilities (along with potential interest and penalties), prompting changes to governance arrangements, considerations to filing positions and increase HMRC scrutiny of historic and future SMR assessments.

Who does it affect?

The SMR were introduced to identify LLP members whose arrangements are more akin to employment than partnership.

Broadly, an LLP member will be treated as an employee for income tax and National Insurance purposes if all three statutory conditions are met. Conversely, failing any one of the conditions will generally preserve self-employed status.

While the BlueCrest decision has implications for all LLPs, those most likely to be affected are firms that have historically relied on Condition B (significant influence) only, to fall outside of the SMR regime.

What do you need to know?

In summary, the Court’s findings focused primarily on Conditions A and B of the SMR (although Condition C remains relevant when considering member status).

If all three statutory conditions are met, an LLP member will be treated as an employee for income tax and National Insurance purposes rather than as a self-employed LLP member.

Condition A – Remuneration Linked to LLP Profits

One of the key indicators of genuine partnership is participation in the profits and losses of the business.

The Supreme Court examined whether members’ remuneration was genuinely linked to the overall profitability of BlueCrest or whether it was, in reality, primarily driven by individual performance.

The Court concluded that the relevant members’ rewards were heavily influenced by the performance of their own activities rather than the overall fortunes of the LLP. Although the remuneration arrangements contained references to LLP profitability, those links were not considered sufficiently meaningful in practice.

The message from the judgment is clear: simply labelling remuneration as “profit share” will not necessarily make it partnership income. The underlying economic reality remains critical.

LLPs operating models where members are rewarded predominantly based on individual performance, formulas or business unit results may therefore wish to revisit whether those arrangements could be viewed as disguised salary.

Condition B – Significant Influence Over the LLP

The Supreme Court’s most significant contribution came in its interpretation of Condition B.

Historically, many LLPs have relied on senior members’ commercial importance, client relationships, revenue generation or operational responsibility when assessing whether they have significant influence over the affairs of the LLP.

The Court has now drawn a much clearer distinction.

Significant influence must be rooted in legally enforceable rights and duties rather than personal stature, seniority or commercial importance.

Key themes emerging from the judgment include:

  • formal governance rights carry greater weight than practical or informal influence;
  • authority delegated through recognised governance structures may be relevant where supported by the LLP’s constitutional arrangements;
  • significant influence must extend to the affairs of the LLP as a whole rather than a specific department, business unit, portfolio or client group;
  • commercial success and operational responsibility do not automatically create significant influence;
  • voting rights and governance powers must be viewed in the context of the LLP’s overall decision-making structure;
  • significant influence does not require outright control, but it must have genuine practical and commercial substance

Perhaps most importantly, the Court made it clear that being important to the business is not the same as having significant influence over the affairs of the LLP.

For many LLPs, this may represent a notable shift in how Condition B should be assessed.

Condition C – Capital Contribution

The third condition considers whether a member has contributed sufficient capital to the LLP.

This was not materially disputed in the BlueCrest litigation and did not form a significant part of the Supreme Court’s analysis.

However, the decision serves as a timely reminder that LLPs relying on capital contributions to support self-employed treatment should ensure those contributions are genuine, properly funded and represent real economic participation in the business and we may expect further examination on this principle through HMRC investigations and potentially Tribunal/Courts clarification.

Why the Decision Matters?

The BlueCrest judgment provides the clearest judicial guidance to date on the operation of the SMR.

Perhaps more importantly, it significantly narrows the extent to which LLPs can rely on informal influence, business prominence or operational responsibility when determining member status.

As a result, LLPs may wish to revisit existing arrangements where:

  • members are rewarded primarily according to individual performance;
  • governance rights and economic participation do not align with the commercial reality of the business;
  • members have significant influence over a segment of an LLP, though less influence over the strategy of the business as a whole;
  • decision-making powers are concentrated in a small group of individuals or entities;
  • significant influence has historically been demonstrated through custom, practice or informal authority rather than formal governance rights;
  • historic SMR reviews were carried out using assumptions based on practical influence rather than legally enforceable rights and duties

Any changes made in response to the decision should be carefully considered and commercially justified. LLPs should also remain mindful of the targeted anti-avoidance provisions within the SMR legislation when reviewing governance or capital arrangements.

What Should You Do Next?

The BlueCrest decision is likely to prompt many LLPs to revisit arrangements that have remained unchanged for years.

We recommend that LLPs consider:

  • whether members can clearly demonstrate significant influence over the affairs of the LLP as a whole;
  • whether remuneration arrangements could be viewed as disguised salary, particularly where rewards are formulaic or heavily linked to individual performance;
  • whether governance arrangements genuinely support LLP member status;
  • whether voting rights and decision-making powers operate as intended in practice;
  • whether delegated authority arrangements, committee memberships and management roles are properly documented and traceable back to the LLP agreement;
  • whether capital contributions relied upon for SMR purposes remain genuine and commercially meaningful;
  • whether there is any potential exposure to historic PAYE, National Insurance, interest or penalties should HMRC challenge the existing position

It is clear, and especially so with the BlueCrest judgement that clear documentation, intent and demonstration of co-temperaneous evidence to back up the assessments against the 3 conditions is critical and addressing the issues only post HMRC enquiry into an LLP’s affairs will significantly weaken any discussions were HMRC to take a contrary view to the interpretation of the Salaried Members rules.
