BCG faces HMRC scrutiny over partner taxation

Boston Consulting Group is facing an HM Revenue and Customs investigation into whether some partners in its UK business should be treated as employees for tax purposes, amid wider scrutiny of limited liability partnership arrangements.

The inquiry concerns the application of the salaried members rules to individuals operating within BCG’s UK partnership. Those rules determine when members of limited liability partnerships should be taxed as employees rather than as self-employed partners.

According to the Financial Times, the investigation could expose BCG to additional tax liabilities, interest, and penalties if HMRC successfully challenges the classification of the members involved.

The rules apply three statutory conditions covering remuneration, influence over partnership affairs, and capital contributions. A member is treated as an employee for tax purposes when all three conditions are satisfied.

One of the principal questions concerns whether a member’s remuneration is genuinely connected to the partnership’s overall profits or operates more like a salary. The legislation also considers whether the individual has significant influence over the partnership and whether they have contributed sufficient capital.

The investigation follows the Supreme Court’s July 2026 judgment in a separate dispute involving BlueCrest Capital Management. The court dismissed BlueCrest’s appeal concerning the interpretation of the salaried members legislation and clarified how remuneration and influence should be assessed.

The ruling established that influence must be considered through the mutual legal rights and duties of the partnership and its members. Personal expertise or commercial importance does not necessarily establish the significant influence required under the statutory test.

The Supreme Court also examined whether remuneration described as discretionary could nevertheless amount to disguised salary because it was not meaningfully affected by the partnership’s overall profits or losses.

Those principles are relevant to professional services organisations operating as partnerships, including consultancies, accountancy practices, and legal businesses. Their members may receive substantial remuneration while exercising different degrees of control over the organisation.

BCG maintains that legal advice supports its treatment of the partners under investigation. The company has not recognised a provision for the new salaried members inquiry because it considers a resulting outflow unlikely, according to the Financial Times.

The consultancy is separately involved in a dispute over capital interests awarded to 63 managing directors and partners. That litigation concerns whether payments associated with the interests should be taxed as income rather than capital gains.

In January 2026, the Upper Tribunal upheld findings that the disputed interests did not amount to genuine interests in the partnership’s capital and that the relevant payments were taxable as income. The judgment addressed arrangements introduced by the consultancy during earlier financial years.

BCG’s latest UK accounts include a reported £101.6m provision connected with the capital-interests matter. The Financial Times also identifies approximately £128.6m in payments or commitments associated with settling the affected partners’ entitlements.

Those amounts relate to the capital-interests arrangements, not the newly reported investigation into salaried members. The separate proceedings involve different provisions of tax law and should not be combined into a single potential liability.

Companies House records confirm that The Boston Consulting Group UK LLP filed accounts for the year ended 31 March 2026 on 26 October. The consultancy has been discussing its tax matters with HMRC, while the result of the newer investigation remains unresolved.

The inquiry places BCG alongside other professional services partnerships examining the financial and organisational consequences of the salaried members rules following the Supreme Court’s decision.
