Setting Up a Single-Family Office in Hong Kong: A Complete Legal Guide

The single-family office (SFO) has become an increasingly prominent feature of Hong Kong's financial landscape. Driven by wealth accumulation across Greater China and Southeast Asia, and by Hong Kong's growing policy support for family offices as a strategic sector, the number of family offices operating in or through Hong Kong has grown substantially. For families considering establishing or formalising an SFO in Hong Kong, the legal and regulatory considerations are significant, and the decisions made at inception have consequences that are difficult and expensive to unwind later.

What Is a Single-Family Office?

A single-family office is an entity that manages the financial and personal affairs of a single family. There is no statutory definition of a "single-family office" in Hong Kong law. In practice, an SFO typically manages the family's investment portfolio, oversees tax and estate planning, coordinates philanthropic activities, and provides family governance support. It is distinguished from a multi-family office (which serves multiple unrelated families, and which typically requires SFC licensing) by its exclusive focus on one family.

The government's SFO incentive programme, introduced through the Inland Revenue (Amendment) (Tax Concessions for Family-owned Investment Holding Vehicles) Ordinance 2023 (the FO Tax Concession Ordinance), has added regulatory substance to what had previously been an informal concept by defining the eligible structures and activities that qualify for the concessionary tax treatment.

Why Hong Kong for a Family Office?

Hong Kong offers several structural advantages as a family office domicile:

• No capital gains tax, estate duty, or gift tax: The absence of these taxes makes Hong Kong a highly efficient base for managing investment portfolios and for intergenerational wealth transfer.
• Territorial tax system: Only Hong Kong-source profits are subject to profits tax. Investment returns generated offshore are typically not taxable in Hong Kong.
• Common law legal system: Trust and estate planning structures governed by Hong Kong law are enforceable in Hong Kong courts, and the legal framework is familiar to international advisers.
• Proximity to China and Asia: For families with operating businesses or investment interests in mainland China, the physical proximity and connectivity of Hong Kong is unmatched among international financial centres.
• Regulatory environment: Hong Kong's regulatory framework for SFOs provides a clear, manageable path for families who want professional investment management without establishing a fully licensed fund management operation.

The Corporate Structure of an SFO

A Hong Kong SFO is typically structured as follows:

Family Investment Holding Vehicle (FIHV)

At the top of the structure sits the family investment holding vehicle: a company, trust, or partnership that holds the family's investment assets. For the SFO tax concession to apply, the FIHV must be a "family-owned investment holding vehicle" as defined in the FO Tax Concession Ordinance. Eligible vehicles include: a Hong Kong private company, a trust with the family as beneficiaries, a partnership, a Cayman or BVI company, or an SFC-authorised OFC or LPF. The FIHV must be at least 95% beneficially owned by a single family (including the family's estate planners, charitable vehicles, and key persons, subject to specific rules).

Single-Family Office Entity

The SFO entity is the operating company that employs staff, provides management services to the FIHV, and carries out the day-to-day functions of the family office. It is incorporated in Hong Kong as a private limited company. The SFO entity charges the FIHV a management fee for its services. The fee income of the SFO entity is subject to Hong Kong profits tax in the normal way.

Investment Manager

Where the FIHV holds a discretionary investment portfolio, an entity within the structure must manage that portfolio. If an employee of the SFO entity manages the family's securities portfolio on a discretionary basis, that activity technically falls within the definition of Type 9 regulated activity (asset management) under the Securities and Futures Ordinance. The SFO exemption discussed below is critical to understanding whether a separate SFC licence is required.

SFC Licensing: The SFO Exemption

A key regulatory question for any SFO is whether its investment management activities require an SFC licence. Under the Securities and Futures Ordinance, managing a securities portfolio on a discretionary basis for another person ordinarily requires a Type 9 (Asset Management) licence. However, the SFO exemption in Schedule 5 of the SFO disapplies the licensing requirement where the asset management activity is carried on by an entity that manages assets solely on behalf of a single family, subject to conditions.

The key conditions for the SFO exemption are:

• The SFO entity manages assets solely on behalf of one single family;
• The SFO entity does not hold client assets (i.e., all assets remain in the FIHV or accounts in the FIHV's name);
• The SFO entity does not carry on other regulated activities; and
• The SFO entity notifies the SFC of its reliance on the exemption by filing a notification form.

Families that wish to allow the SFO entity to manage assets for extended family members, to accept co-investments from third parties, or to provide investment advisory services to persons outside the family will typically cross the line into multi-family office territory, requiring a Type 9 (and potentially a Type 1 or 4) licence. The boundary between a single-family office and a regulated fund manager is fact-specific and should be carefully assessed with regulatory counsel before the structure is finalised.

The FO Tax Concession: How It Works

The FO Tax Concession Ordinance came into force on 19 May 2023 and provides an exemption from Hong Kong profits tax on qualifying transactions carried out by a qualifying FIHV. Key features:

• Qualifying transactions: The tax concession applies to gains and income from specified investments, including listed securities, bonds, exchange-traded funds, private equity interests, real estate investment trusts, and, following 2024 amendments, certain private credit and infrastructure assets. Virtual assets were included in 2024.
• Safe harbour thresholds: The FIHV must hold at least HK$240 million (approximately USD 30 million) in assets under management, or at least HK$30 million in assets if the FIHV has at least two employees in Hong Kong and at least HK$200,000 in annual operating expenditure in Hong Kong.
• Substance requirement: The SFO entity must have at least two full-time employees in Hong Kong (one of whom must not be involved in managing the FIHV's investments) and must incur at least HK$200,000 per year in operating expenditure in Hong Kong.
• Annual assessment: The FIHV's eligibility for the tax concession is assessed annually. A FIHV that fails to meet the conditions in a given year loses the concession for that year.

Governance and Family Constitution

Beyond the corporate and regulatory structure, successful family offices typically invest in family governance: the framework of rules, processes, and structures that govern how the family makes collective decisions about its wealth. A family governance framework might include:

• Family constitution: A non-legally binding document that articulates the family's shared values, investment philosophy, philanthropy objectives, and principles for resolving disputes among family members. Although non-binding, a well-crafted family constitution significantly reduces the likelihood of disputes that escalate to litigation.
• Investment policy statement: A document setting out the investment objectives, risk tolerance, asset allocation parameters, and prohibited investments for the FIHV. Provides a framework for the investment manager and a benchmark for performance evaluation.
• Advisory board or family council: A structured body through which family members can provide input to the investment and governance decisions of the SFO entity without interfering with the operational management. Useful where the family has both actively and passively involved members across multiple generations.
• Succession plan: A documented plan for how the management and governance of the SFO entity will transition as the founding generation ages. May interact with the trust structure and shareholder arrangements governing the SFO entity itself.

Employment and Key Person Considerations

The SFO entity will employ investment professionals, compliance staff, and administrative personnel. Employment contracts for investment professionals in Hong Kong's SFO context should address: the statutory requirements of the Employment Ordinance (including MPF contributions, annual leave, and notice periods); confidentiality obligations covering the family's financial affairs and investment strategies; restrictive covenants limiting the individual's ability to manage assets for competing family offices following departure; and, where the employee is managing the FIHV's securities portfolio, the individual's obligations under the SFC exemption notification.

Where the SFO entity relies on the SFO licensing exemption, the departure of the key investment professional managing the portfolio can have regulatory consequences if the remaining staff do not satisfy the exemption's conditions. Succession planning for key SFO personnel is therefore not merely an HR matter; it has regulatory dimensions that should be addressed in the employment contracts and the governance framework.

Update: what has changed since 2025

The FIHV thresholds are unchanged. The HK$240 million assets under management requirement, the reduced HK$30 million threshold, the HK$2 million minimum Hong Kong operating expenditure and the requirement for at least two qualified full-time employees all remain as they were. Commentary suggesting these were about to be relaxed has not been borne out. The HK$240 million figure is unchanged, but the way it is measured is not. The Bill replaces "net asset value" with "assets value" and repeals the NAV definition, so loans from holders of a direct beneficial interest are no longer deducted in arriving at the figure. Loans from non-participating persons, such as bank borrowings, still are. For a structure sitting just below the threshold because of shareholder loans, that is the difference between qualifying and not qualifying.

What is changing is the asset scope. The Inland Revenue (Amendment) (Preferential Tax Regimes for Funds, Family-owned Investment Holding Vehicles and Carried Interest) Bill 2026, gazetted on 12 June 2026 and still before the Legislative Council, expands qualifying assets by ten new items: loans and private credit, digital assets, immovable property outside Hong Kong, insurance-linked securities, equity interests in non-corporate entities, precious metals, specified commodities, and emission allowances, emission derivatives and carbon credits. The caps are widely misreported: precious metals are capped at 20% by value of the investment portfolio, commodities at 15% by trade volume, and digital assets are not capped at all. It also removes the 5% incidental transaction threshold and relaxes the treatment of family-owned special purpose entities. The Bill takes effect retrospectively from the year of assessment 2025/26, and the IRD has confirmed that eligible taxpayers may claim on that basis pending enactment.

The New Capital Investment Entrant Scheme has been adjusted three times. Residential property was brought in from 16 October 2024, at a minimum of HK$50 million per transaction and counting only up to HK$10 million toward the HK$30 million threshold. From 1 March 2025 the net asset requirement can be demonstrated over six months rather than two years, family jointly-owned assets count pro rata, and investments may be held through a wholly-owned private company including an FIHV or family-owned SPE. From 1 March 2026 that holding company may be incorporated less than six months before the application. The HK$30 million investment threshold itself is unchanged.

The market has grown. The Government reported more than 3,380 single family offices in Hong Kong at the end of 2025, up around 25% over two years. The original 200-family-office target was met ahead of schedule, and a further 220 are targeted for 2026 to 2028.

The Bill also tightens. It introduces an economic substance requirement on funds themselves under new section 20AMA, being at least two qualified Hong Kong employees and at least HK$2 million of Hong Kong operating expenditure, a mandatory tax reporting mechanism under new sections 20AZ to 20AZE backed by new criminal offences, and an anti-round-tripping rule aimed at loans. All of it applies retrospectively to the year of assessment 2025/26.
