Background
HFFX LLP was a limited liability partnership within the GSA investment management group, created in 2010 to house a team of researchers and software developers — led by Managing Member Alexander Gerko — who devised and implemented high-frequency foreign exchange trading strategies. The team had previously received 35% of trading profits (the “Trader Pay-Out”) as employees of another GSA entity; on formation of HFFX, that share rose to 50%. The team’s work continued under secondment to a GSA partnership, with the Trader Pay-Out flowing to HFFX as a profit allocation from that partnership.
To manage how those profits reached individual members, HFFX established a Capital Allocation Plan (CAP) governed by its LLP Deed. Under the CAP, roughly 50% of each individual member’s notional annual profit allocation was instead allocated to a corporate member, GSA Member Limited (GSAM) — a Cayman Islands vehicle held by a business-purpose trust. Mr Gerko would recommend to GSAM how to invest the allocation (in GSA fund shares), when to contribute the proceeds to HFFX as “Special Capital,” and in what proportions to reallocate that Special Capital to individual members in three annual tranches. GSAM retained contractual “absolute discretion” to follow or depart from those recommendations, subject to the rationality constraints recognised in Braganza v BP Shipping Ltd [2015] UKSC 17. Individual members received only an indicative monetary band — not a binding entitlement — and members who departed on bad terms could lose their awards entirely. The tribunals below found, as an unchallenged fact, that tax avoidance was one of the CAP’s main objects: GSAM paid the lower corporation tax rate on the allocated profits, whereas individual members would have faced substantially higher income tax rates had the profits been allocated directly to them. The CAP operated until 2015, when the business transferred to a successor entity, XTX.
HMRC assessed the individual members to income tax on the deferred remuneration received under the CAP, advancing three alternative statutory bases. HFFX and the individual members resisted each. Both the HMRC appeal (concerning section 850 of the Income Tax (Trading and Other Income) Act 2005, ITTOIA) and the individual members’ appeal (concerning section 687 ITTOIA and Chapter 4 of Part 13 of the Income Tax Act 2007) reached the Supreme Court on appeal from the Court of Appeal ([2024] EWCA Civ 813).
The Court’s Holding
Lord Sales delivered the judgment of the Court, with which Lord Lloyd-Jones, Lord Hamblen, Lord Burrows and Lady Rose all agreed. The Court addressed the HMRC appeal first, examining whether section 850 of ITTOIA — which allocates a partner’s share of trading profits in accordance with the firm’s “profit-sharing arrangements” — could reach the amounts diverted to GSAM. The First-tier Tribunal had rejected HMRC’s section 850 claim, finding that the LLP Deed gave GSAM a genuine discretion over reallocations and that individual members held no entitlement, in any relevant tax period, to the profits allocated to GSAM; those profits were GSAM’s own receipts and not a redirection of amounts owed to individuals. The Court treated the HMRC appeal as presenting a core question about the permissible reach of purposive statutory interpretation when the provision in issue imposes a liability to tax — a context in which courts have long recognised that the words of a charging provision cannot be stretched beyond their natural meaning merely to frustrate avoidance.
On the individual members’ appeal, the FTT had upheld HMRC’s alternative arguments: that the deferred remuneration receipts were taxable under section 687 ITTOIA as income from a source (the members’ rights to consideration under the CAP, reinforced by Braganza obligations), and independently under Chapter 4 of Part 13 ITA 2007 as proceeds of arrangements exploiting the earning capacity of individuals in activities of a kind undertaken in a profession — applying the test in IRC v Maxse (1919) 12 TC 41 to the members’ research and strategy-development work. The individual members conceded before the Supreme Court that the reallocations of Special Capital constituted income rather than capital receipts, narrowing the live issues to source (section 687) and the profession/vocation characterisation (Chapter 4). The Court resolved those questions against the background of the detailed factual findings made below and the specific statutory language of each provision.
Key Takeaways
- Section 850 ITTOIA allocates profits according to actual contractual entitlements under the LLP deed; where a corporate member holds a genuine (even if Braganza-qualified) discretion over deferred awards, individual partners cannot be treated as receiving those profits in the tax year they are diverted, regardless of the tax-avoidance purpose of the arrangement.
- The Supreme Court reaffirmed that purposive interpretation of tax-imposing provisions has limits: the court will not extend a charging provision to cover arrangements merely because they achieve a result the legislature would not have intended to permit, where the statutory language does not naturally extend that far.
- Activities of a kind undertaken in a profession (within Chapter 4 of Part 13 ITA 2007) are assessed by the nature of the activities themselves — here, systematic quantitative research and strategy development — and are not excluded merely because the individual is also carrying on a trade or lacks a conventional client base.
- The Braganza rationality obligation, now common ground in LLP deferred-remuneration disputes, does not transform a right to be considered for an award into a vested entitlement sufficient to engage partnership profit-allocation rules under section 850.
Why It Matters
This decision is significant for the structuring of partnership remuneration arrangements, particularly in the asset management and financial services sectors, where deferred-award schemes channelled through corporate members have become common. By addressing the outer boundary of purposive interpretation in the context of section 850, the Supreme Court provides clearer guidance on when profit-diversion arrangements via corporate partners with genuine discretionary powers will — and will not — result in immediate income tax liability for individual partners, even where tax avoidance is a main purpose.
The case also confirms that Chapter 4 of Part 13 ITA 2007 is a broad anti-avoidance provision capable of catching sophisticated professionals whose work is dressed in trading language. Practitioners advising partnerships on remuneration design, and those litigating existing deferred-award structures, must now account for the Supreme Court’s analysis of all three charging provisions — section 850, section 687, and the sales-of-occupation-income regime — as well as the concession that reallocations of Special Capital constitute income rather than capital in the hands of recipients.
