Family Office in Guernsey

Tax regime

Guernsey imposes no capital gains tax, no inheritance tax, no stamp duty on securities transfers, and no value-added tax. These structural absences make it materially attractive for holding and managing long-duration family wealth across generations. Corporate entities are generally subject to a standard zero-percent rate of income tax, with a carved-out 10% rate applying to licensed banking income and a 20% rate on income derived from Guernsey land and property. Family investment vehicles that do not carry on regulated activities and whose income arises from investments rather than Guernsey-source trading will typically fall within the zero-rate regime, though professional advice is essential because the classification of income matters considerably.

Individual residents of Guernsey are subject to income tax at a flat 20% on worldwide income, although an annual cap on liability (the 'tax cap') is available for high-net-worth newcomers who elect into it, capping personal income tax at a fixed ceiling set periodically by the States of Guernsey. Dividend income and investment returns flowing through properly structured family vehicles are not double-taxed at the corporate level where the zero rate applies, and distributions to non-resident beneficiaries are generally not subject to Guernsey withholding tax. Guernsey has signed a network of Tax Information Exchange Agreements (TIEAs) and is a participating jurisdiction under the OECD Common Reporting Standard (CRS) and the US FATCA regime, so transparency with home-country tax authorities of beneficial owners is expected and assumed.

Key regulations

• The Regulation of Fiduciaries, Administration Businesses and Company Directors, etc. (Bailiwick of Guernsey) Law 2020

  Governs licensing of fiduciary and company administration businesses; relevant where a family office provides trustee or directorship services to family structures.

• The Financial Services Commission (Bailiwick of Guernsey) Law 1987 (as amended)

  Establishes the GFSC and its powers to license, supervise and enforce across all regulated financial services in Guernsey.

• The Protection of Investors (Bailiwick of Guernsey) Law 2020

• Income Tax (Substance Requirements) (Implementation) Regulations 2018

  Mandates economic substance for Guernsey-resident entities in relevant sectors, including holding companies and fund management; enforced by the Revenue Service.

• The Criminal Justice (Proceeds of Crime) (Bailiwick of Guernsey) Law 1999 (as amended) and AML/CFT Framework

  Underpins Guernsey's anti-money-laundering and counter-terrorist-financing obligations; family offices conducting regulated activities must have documented AML policies and procedures.

Substance & residency

Guernsey enacted the Income Tax (Substance Requirements) (Implementation) Regulations 2018 (as subsequently amended) in response to the EU Code of Conduct Group's requirements for British Crown Dependencies. Entities that are tax-resident in Guernsey and carry on a 'relevant sector' activity, which includes holding company activity, fund management, banking, insurance, and certain other financial services, must demonstrate genuine economic substance on the island. For a pure holding company (one whose principal business is holding equity stakes or debt in subsidiaries), the substance test is relatively 'reduced': the company must be directed and managed in Guernsey, hold board meetings there with an adequate quorum of physically present directors, and maintain accounting records on the island. The bar is materially higher for entities conducting 'core income-generating activities' such as investment management, where adequate employees, expenditure, and physical premises in Guernsey are required.

For family offices structured as licensed investment managers or as regulated collective investment scheme managers, GFSC licensing conditions impose additional operational requirements: a minimum number of locally based, suitably qualified staff; a local compliance officer and money-laundering reporting officer; appropriate systems and controls; and ongoing regulatory reporting. Where a family office is structured simply as a private investment holding company with no regulated activity, the licensing burden is lower but the substance test still applies if the entity is Guernsey-tax-resident. Principals who relocate personally to Guernsey, as some ultra-high-net-worth families do, must obtain residential qualifications under Guernsey's population management framework, which is administered separately from the tax and regulatory regimes and involves waiting periods or qualification through purchase of open-market property.
