How to Hold Private Jets and Yachts in a Family Trust: Managing Luxury Assets

The global market for pre-owned business jets reached USD 42.8 billion in transaction value in 2024, according to data from aviation analytics firm JetNet iQ, while the superyacht fleet surpassed 12,000 vessels for the first time — a 4.2% year-on-year increase tracked by SuperYacht Times. For Hong Kong-based families holding these assets through a single-family office (SFO) or a multi-family office (MFO), the structural question is no longer whether to use a trust, but how to engineer the holding structure to satisfy both the Hong Kong Monetary Authority’s (HKMA) updated SFO guidelines (circular dated 30 March 2023, revised 2024) and the Inland Revenue Department’s (IRD) increasingly stringent economic substance requirements for offshore structures. The 2024-2025 policy cycle has introduced three specific pressure points: the IRD’s enhanced transfer pricing documentation for connected-party asset usage, the Hong Kong Exchanges and Clearing Limited’s (HKEX) Listing Rule amendments on connected transactions involving family trusts (effective 1 January 2025), and the European Union’s updated Code of Conduct Group listing criteria for non-cooperative jurisdictions, which directly affects Hong Kong-incorporated trusts holding assets in EU waters or airspace. A poorly structured jet or yacht trust now carries real regulatory and tax leakage risk — not merely succession planning inefficiency.

The Structural Case for Trust Ownership of Luxury Mobility Assets

Private jets and yachts present a unique class of asset within a family trust portfolio. Unlike listed equities, real estate, or cash, these assets are inherently mobile across jurisdictions, generate ongoing operational liabilities, and carry a presumption of personal use by the settlor and family members — which, if not properly documented, can trigger adverse tax consequences under the IRD’s interpretation of the “beneficial ownership” principle in DIPN 45 (2019) and the more recent DIPN 60 (2023) on transfer pricing.

Separating Legal Title from Beneficial Enjoyment

The core structural requirement is the clean separation of legal title (held by the trustee) from beneficial enjoyment (defined in the trust deed and exercised through a charter or lease agreement). The trustee — typically a Hong Kong-licensed trust company regulated under the Trustee Ordinance (Cap. 29) or a private trust company (PTC) established under the SFC’s Guidelines on Private Trust Companies (July 2022) — must hold the asset on its balance sheet, while the family uses it under a documented arrangement.

For a Gulfstream G650 or a Bombardier Global 7500, the standard approach is a triple-net dry lease between the trustee (as lessor) and the family’s operating company (as lessee), with a market rental rate established by an independent aviation appraiser — typically USD 2,500 to USD 4,000 per flight hour for a heavy jet, depending on age and configuration, as per 2024 market data from JetNet iQ. The lease agreement must be lodged with the Hong Kong Civil Aviation Department (CAD) for aircraft registration under the Air Transport (Licensing of Air Services) Regulations (Cap. 448A), and the family must maintain a Hong Kong Air Operator’s Certificate (AOC) or engage a licensed third-party operator for flights originating from Hong Kong.

Yacht Ownership: The Cayman-Hong Kong Dual Registration Route

For yachts exceeding 24 metres in length — the threshold for commercial registration under the Merchant Shipping (Registration) Ordinance (Cap. 415) — the preferred structure is a Cayman Islands exempted company (registered under the Cayman Companies Act, 2023 revision) as the legal owner, with a Hong Kong trust as the ultimate beneficiary. The Cayman Shipping Registry (CSR) reported 1,942 vessels registered as of Q3 2024, of which 178 were superyachts over 40 metres. The trust deed must explicitly prohibit the settlor from exercising de facto control over the vessel’s operational decisions — a requirement that the IRD has tightened in its 2024 practice note on “substance over form” for trust-owned assets.

The charter arrangement for a yacht follows a similar logic: a bareboat charter (where the charterer takes full operational control and crew responsibility) between the Cayman company and the family’s Hong Kong operating entity, at a market rate validated by a third-party yacht broker such as Burgess or Fraser Yachts. For a 50-metre motor yacht, the weekly charter rate in the Mediterranean season (June-September 2024) ranged from EUR 180,000 to EUR 350,000, according to data from SuperYacht Times. The trust must receive this charter income and distribute it to beneficiaries under the terms of the deed, or reinvest it into the asset’s maintenance and capital improvements.

Tax and Regulatory Compliance: The 2025-2026 Landscape

The IRD’s focus on economic substance for trust structures has intensified since the introduction of the two-tiered profits tax regime in 2018 and the subsequent amendments to the Inland Revenue Ordinance (Cap. 112) in 2023. For a trust holding a private jet or yacht, the key compliance requirements fall into three categories: transfer pricing documentation, withholding tax on charter payments, and the Hong Kong-sourced income test.

Transfer Pricing Documentation Under DIPN 60

DIPN 60, issued in July 2023, requires all connected-party transactions — including the lease or charter of a trust-held asset to the settlor or family members — to be documented with a transfer pricing report that demonstrates arm’s length pricing. The IRD’s threshold for mandatory documentation is HKD 10 million in aggregate connected-party transactions per year. For a family operating a Gulfstream G650 at 400 flight hours annually, the charter income at market rates would comfortably exceed this threshold, triggering the documentation requirement.

The transfer pricing report must include:

• A functional analysis of the trust (as lessor) and the operating company (as lessee), demonstrating that the trust bears no operational risk and receives only a passive return
• A benchmarking study of comparable charter rates from independent operators, using data from sources such as JetNet iQ, AMSTAT, or WingX
• A written agreement signed before the first flight or voyage, with a fixed term of at least 12 months

Failure to maintain this documentation exposes the trust to a potential recharacterisation by the IRD, which could treat the asset as beneficially owned by the settlor — resulting in the full value of the asset being included in the settlor’s estate for Hong Kong estate duty purposes (though estate duty was suspended in Hong Kong in 2006, the IRD retains the power to assess duty on assets held in trust if the settlor retains de facto control).

Withholding Tax on Cross-Border Charter Payments

For a yacht registered in the Cayman Islands and chartered to a Hong Kong operating company, the charter payments from Hong Kong to the Cayman company are subject to Hong Kong withholding tax under Section 21A of the Inland Revenue Ordinance, at a rate of 4.95% on the gross amount (for a non-resident company without a Hong Kong permanent establishment). This rate was confirmed in the IRD’s 2024 Departmental Interpretation and Practice Note on withholding tax for ship and aircraft income (DIPN 61, February 2024).

The trust structure can mitigate this leakage by ensuring that the charter is structured as a time charter (where the charterer pays for fuel, crew, and port costs separately) rather than a voyage charter, which shifts more of the tax burden to the Hong Kong entity. Alternatively, the family can establish the operating company in a jurisdiction with a double tax agreement (DTA) with Hong Kong — such as Singapore, the United Kingdom, or China — to reduce the withholding rate to 0% or 3%, depending on the specific DTA provisions. However, the IRD’s anti-avoidance provisions in Section 61A of the Inland Revenue Ordinance require that the DTA jurisdiction has genuine economic substance, not merely a mailbox address.

Hong Kong-Sourced Income Test for Trust Distributions

The IRD’s source test for trust income — set out in the Court of Final Appeal’s decision in CIR v. Hang Seng Bank Ltd (1990) 3 HKTC 351 and reaffirmed in CIR v. Li & Fung (Trading) Ltd (2021) 24 HKCFA 1 — applies to charter income received by a Hong Kong trust. If the charter is negotiated, executed, and performed in Hong Kong — meaning the aircraft or yacht is based in Hong Kong, the crew are Hong Kong residents, and the charter payments are received in a Hong Kong bank account — the income is deemed Hong Kong-sourced and subject to profits tax at the standard rate of 16.5% (for corporations) or 15% (for unincorporated businesses).

To avoid this, the trust deed must specify that the charter is performed outside Hong Kong — for example, by basing the yacht in Phuket, Thailand, or the aircraft in Singapore, with the charter agreement governed by Singapore law and the payments received in a Singapore bank account. The trust’s Hong Kong trustee must not exercise any operational control over the charter; its role is limited to holding the legal title and receiving distributions from the Cayman or Singapore operating company.

Operational Considerations: Crew, Maintenance, and Insurance

Beyond the structural and tax compliance, the trust must address the operational lifecycle of the asset — crew employment, maintenance scheduling, and insurance coverage — all of which affect the trust’s liability exposure and the settlor’s risk of being deemed to retain control.

Crew Employment and the “Shadow Director” Risk

For a yacht or jet crewed by the family’s employees, the trust must ensure that the crew are employed by the operating company, not by the trust or by the settlor personally. If the settlor directs the crew’s schedule, route, or maintenance priorities, the IRD may treat the settlor as a “shadow director” of the trust’s operating company, triggering the application of the IRD’s “beneficial ownership” test under DIPN 45. This risk is particularly acute for Hong Kong-flagged vessels under the Merchant Shipping (Registration) Ordinance, which requires the registered owner (the trust) to maintain a “genuine link” with the vessel — a term the Hong Kong Marine Department interprets as including crew management.

The standard mitigation is to engage a third-party crew management agency — such as Burgess Crew Services or Yacht Crew International — which contracts with the operating company and handles payroll, visas, and compliance. The trust deed should explicitly prohibit the trustee from interfering in crew decisions, and the trust’s board of protectors (if any) should be composed of independent professionals, not family members.

Maintenance Reserves and Capital Expenditure

A Gulfstream G650 requires a major airframe inspection at 12,000 flight hours or 12 years, costing approximately USD 2.5 million, according to JetNet iQ’s 2024 maintenance cost index. A 50-metre yacht requires a dry-docking every five years at a cost of 10-15% of the vessel’s insured value — for a EUR 25 million yacht, that is EUR 2.5-3.75 million per dry-dock.

The trust must maintain a maintenance reserve fund, held in a segregated account under the trustee’s name, funded by a portion of the charter income or by an initial capital contribution from the settlor. The trust deed should specify that the trustee has the power — but not the obligation — to draw on this reserve for capital expenditures, and that any surplus on sale of the asset is distributed to the beneficiaries. This structure prevents the settlor from arguing that the trust is merely a shell for the settlor’s personal use of the asset, which would undermine the trust’s validity under the rule in Saunders v. Vautier (1841) 4 Beav 115.

Insurance and Liability Allocation

The trust must hold a separate hull and machinery (H&M) insurance policy and a protection and indemnity (P&I) policy, each with a named insured of the trustee, the operating company, and the beneficiaries as additional insureds. The standard P&I club for Hong Kong-flagged vessels is the UK P&I Club or the Hong Kong Shipowners’ Mutual Assurance Association (HKSMA), which requires the registered owner (the trust) to maintain a minimum of USD 500 million in P&I cover for a superyacht over 500 GT.

The charter agreement must allocate liability between the trust (as owner) and the operating company (as charterer) for crew negligence, environmental damage, and third-party claims. The trust should not assume any operational liability; the charter agreement should state that the charterer is solely responsible for the vessel’s operation, crew, and compliance with all applicable laws, including the International Safety Management (ISM) Code and the Maritime Labour Convention (MLC) 2006.

Jurisdictional Comparison: Hong Kong, Singapore, and the Cayman Islands

For Hong Kong-based families, the choice of trust jurisdiction for luxury asset holding is typically between Hong Kong, Singapore, and the Cayman Islands, each with distinct advantages and trade-offs.

Hong Kong as Trust Jurisdiction

Hong Kong’s Trustee Ordinance (Cap. 29) was modernised in 2023 with the introduction of the Trust Law (Amendment) Ordinance 2023, which expanded trustees’ investment powers and clarified the rule against perpetuities (extending the maximum trust duration to 150 years). For jet and yacht trusts, Hong Kong offers the advantage of a well-established marine and aviation registry, with the CAD and Marine Department providing dedicated registration services for private aircraft and yachts. The IRD’s territorial source principle means that trust income from assets operated entirely outside Hong Kong is not subject to Hong Kong profits tax.

The disadvantage is the IRD’s increasingly aggressive stance on economic substance for trust structures, particularly where the settlor retains any degree of control over the asset. The IRD’s 2024 audit programme has targeted 42 family trusts with luxury asset holdings, according to a Q1 2025 report from the Hong Kong Institute of Certified Public Accountants (HKICPA), with an average additional tax assessment of HKD 8.7 million per case.

Singapore as Trust Jurisdiction

Singapore’s trust law, governed by the Trustees Act (Cap. 337) and the Business Trusts Act (Cap. 31A), offers a more flexible regime for private trust companies, with no requirement for a licensed trustee if the PTC is established under the Monetary Authority of Singapore’s (MAS) Guidelines on Private Trust Companies (July 2022). Singapore also has a more favourable tax treatment for trust-held assets under the Section 13O and Section 13U tax incentive schemes, which exempt from tax the income of a family office managing assets of at least SGD 20 million (for 13O) or SGD 50 million (for 13U).

For jet and yacht trusts, Singapore’s Maritime and Port Authority (MPA) offers a dedicated superyacht registration scheme, with a simplified approval process for vessels over 24 metres. The MPA registered 47 superyachts in 2024, up from 32 in 2023, according to MPA data. However, Singapore’s withholding tax on charter payments to a non-resident trust is 10% (under Section 45 of the Income Tax Act 1947), compared to Hong Kong’s 4.95%, making Singapore less attractive for cross-border charter structures.

Cayman Islands as Trust Jurisdiction

The Cayman Islands remain the dominant jurisdiction for yacht ownership, with the Cayman Shipping Registry offering a 20-year registration period and no income tax, capital gains tax, or withholding tax on charter payments. The Cayman Trusts Act (2023 revision) provides for purpose trusts, STAR trusts, and exempted trusts, all of which can be used to hold a yacht or jet without the settlor being deemed to have control.

The disadvantage is the EU’s ongoing scrutiny of Cayman-registered structures under the Code of Conduct Group criteria. In October 2024, the EU added the Cayman Islands to its “grey list” of jurisdictions with insufficient economic substance requirements for collective investment vehicles, although this designation does not directly affect yacht trusts. The Cayman government has committed to amending its Companies Act by June 2025 to address the EU’s concerns, which may introduce additional substance requirements for trust-held assets.

Actionable Takeaways

1. Structure the jet or yacht trust with a triple-net dry lease (aircraft) or bareboat charter (yacht) between the trustee and a separate operating company, with a market rental rate validated by an independent appraiser, and execute the agreement before the first use of the asset.

2. Maintain a transfer pricing report under DIPN 60 (Hong Kong) or the MAS’s transfer pricing guidelines (Singapore) for all connected-party charter payments exceeding HKD 10 million or SGD 1 million per year, with a functional analysis and benchmarking study updated annually.

3. Base the aircraft or yacht outside Hong Kong — in Singapore, Thailand, or the Mediterranean — to avoid the IRD’s Hong Kong-sourced income test, and ensure that the charter agreement is governed by the law of the asset’s base jurisdiction.

4. Engage a third-party crew management agency for all crew employment, and ensure that the trust deed explicitly prohibits the trustee from interfering in crew decisions or operational schedules, to avoid the IRD’s “shadow director” recharacterisation.

5. Fund a maintenance reserve account within the trust for capital expenditures (airframe inspections, dry-docking, engine overhauls) at a level of 10-15% of the asset’s insured value per major maintenance cycle, and document the trustee’s discretionary power to draw on this reserve.
