Navigating Jersey's Tax Landscape: A UK Tax Barrister's Perspective for Jersey Professionals

Jersey occupies a unique position in the international tax landscape. As a Crown Dependency with its own legislature and tax system, it is neither part of the United Kingdom nor a member of the European Union — yet its proximity to the UK, its historical constitutional ties, and the overwhelmingly UK-connected nature of its financial services industry mean that Jersey practitioners are in constant engagement with UK tax law. The island's finance industry — comprising trust companies, fund administrators, banking institutions, law firms, and accountancy practices — manages assets worth hundreds of billions of pounds, a substantial proportion of which have UK-connected beneficial owners. Jersey trusts, companies, and partnerships are widely used in wealth structuring, estate planning, and investment fund arrangements for individuals and families with UK domicile, UK residence, or UK-situs assets. For Jersey professionals, the UK tax implications of the structures they administer are not merely academic concerns — they are matters of practical compliance, commercial risk, and client service. A Jersey trust company that fails to appreciate the UK tax treatment of distributions to UK-resident beneficiaries, or a Jersey law firm that advises on a corporate restructuring without considering the UK capital gains tax consequences, exposes both itself and its clients to significant financial and reputational risk.

The UK taxation of trusts is one of the most complex areas of the UK tax code, and Jersey-administered trusts with UK connections are squarely within HMRC's sights. The key provisions that Jersey trust companies and their legal and accounting advisers must understand include the settlements legislation for income tax purposes (Part 5 of the Income Tax (Trading and Other Income) Act 2005), the capital gains tax provisions for non-resident trusts (Schedule 5 to the Taxation of Chargeable Gains Act 1992), and the inheritance tax treatment of trust property (Part III of the Inheritance Tax Act 1984). The settlements legislation can attribute the income of a Jersey trust to a UK-resident settlor where the settlor retains an interest in the trust — a concept that is broadly defined and catches many arrangements that settlors may not appreciate give rise to a UK tax charge. The capital gains tax provisions for non-resident trusts impose a charge on UK-resident beneficiaries who receive capital payments from trusts that have realised gains, with complex matching and supplementary charge rules that can produce counterintuitive results. Finance Act 2025 has added further complexity for Jersey trust companies. The reforms to the non-dom regime have fundamentally changed the treatment of trusts established by individuals who are or become deemed domiciled in the UK. The protections previously available to excluded property trusts are now subject to new conditions, and the temporary repatriation facility introduces a time-limited opportunity for settlors and beneficiaries to bring offshore trust funds to the UK at reduced rates — but only if the computational and procedural requirements are precisely met. Jersey practitioners need access to specialist UK tax counsel who can advise on these provisions in the context of specific trust arrangements. Daniel Feingold has extensive experience advising Jersey trust companies on the UK tax treatment of trust structures, distributions, and reorganisations.

The introduction of economic substance requirements in Jersey — pursuant to the Taxation (Companies — Economic Substance) (Jersey) Law 2019, enacted in response to the EU Code of Conduct Group's assessment — has been a watershed moment for Jersey's finance industry. Companies carrying on relevant activities in Jersey must now demonstrate adequate substance on the island, including direction and management, adequate employees, adequate expenditure, and core income-generating activities. From a UK tax perspective, economic substance in Jersey serves a dual function. First, it supports the analysis that a Jersey company is genuinely tax-resident in Jersey rather than centrally managed and controlled from the UK — a critical determination under the UK's common law test for corporate residence. Second, adequate substance strengthens the position that a Jersey company is the beneficial owner of income for the purposes of the UK-Jersey double taxation arrangement, and that the company has a genuine commercial purpose beyond the obtaining of tax advantages. HMRC has become increasingly sophisticated in its scrutiny of Jersey structures. The exchange of information under the Tax Information Exchange Agreement (TIEA) between the UK and Jersey, supplemented by the automatic exchange of financial account information under the Common Reporting Standard (CRS) and the Country-by-Country Reporting framework, provides HMRC with unprecedented visibility into the affairs of UK-connected persons using Jersey structures. Jersey law firms, accountancy practices, and trust companies need to be confident that the structures they establish and administer can withstand HMRC challenge. This means not only ensuring compliance with Jersey's own substance requirements but also considering how the structure will be analysed under UK domestic tax law and the UK-Jersey double taxation arrangement.

The double taxation arrangement between the UK and Jersey (which, as a Crown Dependency arrangement rather than a treaty, has a somewhat different legal basis from the UK's bilateral tax treaties) governs the allocation of taxing rights between the two jurisdictions and provides mechanisms for the relief of double taxation. For Jersey professionals, an understanding of this arrangement is essential to advising clients on the UK tax treatment of income and gains arising from Jersey structures. Key provisions include the treatment of dividends paid by Jersey companies to UK-resident shareholders (where the arrangement limits the UK's right to tax but does not eliminate it), the treatment of interest and royalties, and the provisions governing the taxation of capital gains on the disposal of shares in Jersey companies that derive their value from UK real property. In practice, the most contentious issues tend to arise in relation to the beneficial ownership of income. HMRC has adopted an increasingly purposive interpretation of beneficial ownership, consistent with the approach endorsed by the Supreme Court in other contexts, and may challenge the entitlement to treaty benefits where it considers that a Jersey entity is acting as a conduit or agent rather than the true beneficial owner of the income in question. For Jersey trust companies administering structures that receive UK-source income — such as rental income from UK property or dividends from UK companies — these issues are of direct practical importance. A specialist UK tax barrister can provide the authoritative analysis needed to determine whether treaty benefits are available and, if HMRC challenges the position, to defend it through the dispute resolution process.

The compliance landscape for Jersey structures with UK connections has become significantly more onerous in recent years. UK-resident trustees (and non-resident trustees with UK tax liabilities) must register with HMRC's Trust Registration Service and maintain up-to-date information about the trust, its beneficial owners, and its assets. The failure to register or to update information can result in penalties. The Automatic Exchange of Information under the CRS means that financial institutions in Jersey automatically report account information relating to UK tax-resident persons to the Jersey tax authority (Revenue Jersey), which in turn exchanges that information with HMRC. This creates a powerful cross-referencing capability that HMRC uses to identify discrepancies between information received from Jersey and the UK tax returns filed by the relevant taxpayers. For Jersey accountancy practices preparing UK tax returns for clients with Jersey structures, and for trust companies providing information to facilitate those returns, the accuracy and completeness of the information provided is paramount. Errors or omissions — even if inadvertent — can trigger HMRC enquiries, penalties under the failure-to-correct provisions introduced by Finance (No 2) Act 2017, and potentially criminal investigation in cases of suspected deliberate non-compliance. Solicitor firms in Jersey advising on the establishment of new structures, or the restructuring of existing ones, must ensure that the UK reporting obligations are understood and factored into the design of the arrangement. A specialist UK tax barrister can advise on the scope of the reporting obligations, the interaction with professional privilege, and the consequences of non-compliance.

Jersey professionals encounter UK tax issues across a wide range of client matters. Common scenarios in which specialist UK tax counsel should be sought include the establishment of a new trust or company structure for a client with UK connections (to ensure that the UK tax treatment is understood and that the structure achieves its intended objectives), the distribution of trust assets to UK-resident beneficiaries (to determine the UK tax treatment and optimise the timing and form of distributions), and the restructuring of existing arrangements in light of legislative changes such as the Finance Act 2025 non-dom reforms. Other scenarios include the disposal of UK real property held through Jersey structures (where the UK non-resident capital gains tax rules introduced by Finance Act 2019 may apply), the death of a settlor or beneficiary with UK domicile or deemed domicile (triggering inheritance tax issues), and HMRC enquiries into the affairs of UK taxpayers with Jersey connections. In each of these situations, the Jersey professional's role is enhanced — not diminished — by the involvement of specialist UK tax counsel. The barrister provides the authoritative UK tax analysis; the Jersey professional provides the local law expertise, the knowledge of the client's affairs, and the ongoing relationship management. The result is a collaborative approach that serves the client's interests more effectively than either professional could achieve alone.

Daniel Feingold has a long-standing practice advising Jersey trust companies, law firms, accountancy practices, and private wealth managers on UK tax matters.
