Primary source(s): HMRC v BlueCrest Capital Management (UK) LLP [2026] UKSC 18, Supreme Court judgment, 1 July 2026.
Background: The Supreme Court unanimously dismissed BlueCrest’s appeal on the interpretation of the salaried members rules. Application of the significant-influence condition was remitted to the First-tier Tribunal. RPC reports that HMRC is now writing to LLPs to check members’ tax status. The rules treat a member as an employee for tax and National Insurance only where all three statutory conditions are satisfied.
“Partner” is a satisfying word to acquire. It is less satisfying to discover that the tax treatment depends on something more demanding than the new business card.
HMRC has begun writing to limited liability partnerships about whether their members should be taxed as employees. RPC’s November report links the compliance activity to BlueCrest, a Supreme Court case involving an investment-management LLP. The implications extend to professional firms organised in the same way.
The law does not treat every LLP member as a salaried employee. It asks three questions, and all three conditions must be met. Missing that conjunction would turn a targeted tax rule into a much broader claim than the legislation supports.
Condition A concerns pay. It applies where at least 80% of expected remuneration is disguised salary: fixed pay, variable pay unrelated to overall LLP profits or losses, or pay not affected in practice by those overall results.
Condition B concerns significant influence over the LLP’s affairs. Condition C concerns capital: whether the member’s contribution is less than 25% of expected disguised salary. A member outside any one condition is outside the salaried members rules.
BlueCrest matters particularly for the first two. Calling remuneration a profit share is insufficient if its practical relationship to the firm’s profits does not support that description. A formula can use the language of partnership while delivering something much closer to a salary.
Influence needs equally careful treatment. Commercial importance, seniority and substantial day-to-day responsibility are not, on their own, qualifying influence. The relevant influence must derive from legally enforceable rights and duties and be significant in relation to the LLP’s affairs viewed as a whole.
It is too narrow, however, to say that every right must be written directly into the main partnership agreement. Authority can be delegated within the legal governance framework. Nor must a member control the firm single-handedly: meaningful participation in important decisions can matter.
The Supreme Court dismissed the appeal, but the application of Condition B was sent back to the tribunal. That qualification should not disappear beneath a headline announcing that every disputed partner has finally been classified.
The potential consequences are substantial. Employee treatment generally brings PAYE obligations and employer National Insurance. RPC recommends examining remuneration, capital and governance together, with evidence supporting the firm’s analysis rather than a last-minute explanation after a letter arrives.
For law firms, the useful response is a review of each relevant member’s position. Who has which rights? How does the pay actually change? What capital has been contributed? The answers need to describe the arrangement that exists, not the one a title suggests.
A partner can have considerable standing and still have little legal say in the business. HMRC is asking firms to show the difference.
