🇸🇬Trust Structuring in Singapore: Legacy Trust, PTC, Family Office Trust

Concept

A trust in Singapore is an obligation for a trustee to hold assets in their own name and manage them for the benefit of beneficiaries according to the terms of a trust deed. The legal owner is the trustee; the economic owner is the beneficiaries. This arrangement solves three family objectives: succession without probate, asset protection from external claims, and controlled distribution of capital across generations.

Singapore operates under English trust law. The foundational statute is the Trustees Act 1967: the 2004 reform protected only the settlor's powers of investment and asset management (s 90(5)) and, through s 89 and the Civil Law Act 1909, fixed the duration of a trust at 100 years; Singapore has no statutory non-charitable purpose trust. A comparison of these parameters with Jersey and New Zealand is in choosing a trust jurisdiction; trust-jurisdictions-map widens it to fifteen centres, including Hong Kong, Cayman, Liechtenstein, DIFC and the US trust states, where Singapore stands out for its 100-year period and the absence of a statutory purpose trust. How the same Singapore trust is read once a beneficiary moves to the UK, Italy, Spain or another of twelve destinations is set out in relocating-with-a-trust. Licensed trust companies and Private Trust Companies are regulated by MAS under the Trust Companies Act 2005. The tax regime is set out in the IRAS e-Tax Guide: Income Tax Treatment of Trusts and the Income Tax (Exemption of Income of Foreign Trusts) Regulations.

How a Trust Works

Settlor

Transfers assets into the trust and records their wishes in the trust deed and letter of wishes. After the transfer, legal title passes to the trustee; the settlor ceases to be the owner of the assets.

Trustee

The legal owner of the assets. Acts strictly within the framework of the trust deed and in the interests of the beneficiaries. In practice—a licensed Singapore trust company (DBS Trustee, HSBC Trustee, Equity Trust) or a Private Trust Company with an engaged licensed administrator.

Beneficiaries

Receive the economic benefit—distributions at the trustee's discretion; in a discretionary trust without fixed proportions. The class of beneficiaries and distribution principles are described in the trust deed.

Protector

An optional role. Oversees key trustee decisions: change of trustee, amendment of the beneficiary list, significant dispositions. Protects the settlor's wishes without returning legal control to them.

A letter of wishes is a non-binding document. It communicates the settlor's intentions to the trustee but does not turn a discretionary trust into a sham. If the settlor continues to effectively control the assets through the trustee directly, tax authorities and courts will treat the structure as a sham trust: for tax purposes the assets remain with the settlor, and the protective effect is lost.

DBS Trustee Trust Range

DBS Trustee Limited is a licensed trust company under MAS, a 100% subsidiary of DBS Bank, operating since 1975. It commonly serves as institutional trustee for liquid portfolios and family trusts, and as PTC administrator.

Legacy Trust

A discretionary trust for liquid assets—cash, listed equities and bonds, fund units. The settlor transfers assets to the trustee, beneficiaries are defined by class, distributions are at the trustee's discretion with reference to the letter of wishes.

The basic scenario for succession without special features: avoid probate, separate family management from ownership, ensure continuity of portfolio management after the settlor's passing.

Customised Legacy Trust

The same structure, but tailored for beneficiaries in different tax systems:

• UK residents—accounting for Inheritance Tax and the 2025 Resident Non-Dom reform;
• US citizens—through a foreign grantor trust or non-grantor trust with throwback adjustments;
• EU residents—with requirements for economic substance and anti-deferral regimes;
• charitable and purpose structures.

The same Singapore trust produces different tax outcomes for UK, US, and EU participants. Here, tailoring the trust deed to the tax logic of the beneficiaries is more important than a standard template.

Family Office Trust

The trust works in conjunction with a single- or multi-family office, often through a VCC and Section 13O / 13U. The trustee holds VCC shares, and the VCC manages the family's investment portfolio through the family office.

This way the trust adds succession and protection on top of the investment structure. The Section 13O / 13U tax regime applies to the VCC or fund within the structure, but not to the trust itself.

The trust holds the top ownership tier, the VCC the investment one, and the incentive attaches to the fund.

Legacy Plus Trust

For assets not reducible to a standard custody portfolio:

• pre-IPO shares with a 12–18 month listing horizon;
• a substantial shareholding in a listed company (substantial-shareholder, >5%);
• commercial real estate in Singapore and Hong Kong.

The trustee takes on operational procedures for such assets under a separate mandate and conducts individual due diligence. More expensive and slower than a standard trust, but reduces the risk that the trust deed will be incompatible with actual asset management.

Private Trust Company (PTC)

A corporate trustee established by the client or family office itself. The board of directors includes family members and trusted advisors; investment decisions remain closer to the family. Suitable for complex assets: operating businesses, unlisted shares, concentrated positions, real estate.

Under the Trust Companies (Exemption) Regulations (Cap. 336, Rg 1), reg 4(1)(a), a PTC may be exempt from MAS licensing but must, under reg 4(2), engage a licensed trust company to provide trust administration services covering AML / KYC and ongoing service. In practice, this role is performed by DBS Trustee or an independent Singapore provider.

Tax Regimes

Trust taxation should not be confused with fund regimes. Here are three separate structures:

If at least one beneficiary is a Singapore tax resident, their share of income is taxed at the beneficiary level at personal rates. A non-resident beneficiary's share is taxed at the trustee level at the flat trustee rate of 17% (IRAS, tax on non-resident beneficiaries); the 24% figure that is often quoted is the rate for non-resident individuals, and it does not apply at the trustee level.

Section 13G and the Trust's Foreign Income

The baseline principle: trust income from sources outside Singapore and not remitted into the country is as a rule outside Singapore tax. To exempt income that is received in Singapore, the trust has to qualify as an eligible trust — under section 13G (qualifying foreign trust), or under the fund regimes 13O / 13U where it is tied into a fund structure.

13G is designed for foreign settlors and beneficiaries: where the conditions are met, the income of a qualifying foreign trust and of its holding companies is exempt. Where the capital is serviced through a family office, the economic thresholds and local business spending are counted under the 13O / 13U rules instead.

From 1 January 2025 AUM under the fund regimes is measured by designated investments. LBS is likewise tied to size, but there are two grids, and what separates them is not the size of the fund but who manages it. A fund run by the family's own single family office (MAS conditions from 5 July 2023): up to SGD 50m — from SGD 200,000 a year; SGD 50m to 100m — from SGD 500,000; from SGD 100m — from SGD 1m. A fund run by a third-party licensed manager (FDD Cir 10/2024): SGD 200,000 at AUM up to SGD 250m, SGD 300,000 from SGD 250m to SGD 2bn, SGD 500,000 from SGD 2bn. The schemes themselves are extended to 31 December 2029.

The trust business is licensed: the trust is administered by a licensed trust company under the Trust Companies Act and MAS supervision, which sets the economic-substance requirements; a PTC is permitted where a licensed trustee administers it. The full structure is therefore assembled from a trustee, a family office and, where needed, a fund.

Cost and Economic Threshold

With assets below S$2M and beneficiaries in one jurisdiction, a trust is rarely justified. For such situations, a will, life insurance, and bank nominee arrangements work more precisely.

Who It Suits and Who It Doesn't

Suits

• A family with assets from S$3M+ and beneficiaries in multiple countries.
• A founder before IPO, business sale, or M&A with a 12–24 month horizon.
• UHNW client with non-resident Singapore beneficiaries—Section 13G provides direct tax benefit.
• A family with an operating business, where a PTC preserves control at the board level.
• A structure with VCC and Section 13O / 13U, where the trust holds the top ownership tier.

Does Not Suit

• Assets below S$2M, beneficiaries in one country.
• Settlor not prepared to genuinely transfer legal ownership to the trustee.
• Main asset requires daily operational management not describable in a trust deed.
• Family seeking a "tax wrapper" without management, reporting, and economic substance.
• Beneficiary composition creates heavier taxation than direct ownership or a fund structure.

Risks

Control (sham trust)

If the settlor continues to effectively control the assets through the trustee, tax authorities and courts will deem the trust a sham. Legal consequence—assets revert to the settlor for tax purposes, protective effect is lost. Control point—genuine delegation of decisions to the trustee, fixed procedures, documented board minutes.

Tax Mismatch by Beneficiaries

UK, US, EU, and Singapore beneficiaries recognize income, distributions, grantor status, anti-deferral, and inheritance taxation differently. The same trust can be neutral for one beneficiary and toxic for another. Resolved by distributing assets across multiple structures or individually tailoring the deed.

Asset Compatibility

A liquid portfolio is easily transferred to a trustee. An operating business, pre-IPO stake, or large position in a listed company requires separate due diligence and often Legacy Plus or PTC. A standard precedent deed does not work in such cases.
