How much money do you actually need for a Singapore family office?

The floors, and which kind of fund each one belongs to

The single most common error in the published guides is to quote a number from the wrong rulebook. MAS runs two sets of conditions under the same section names. Non-SFO funds are managed by a licensed fund management company; SFO funds are the family office case, managed by a single family office exempt from licensing. The S$5 million figure that circulates as the Singapore family office minimum is the non-SFO entry condition: a Section 13O or 13OA non-SFO fund with an award commencing on or after 1 January 2025 must have at least S$5 million in AUM in Designated Investments at the point of application, with a grace period to the end of the third year of assessment. It is an entry test for a fund run by a licensed manager, and the annual minimum that used to sit behind it was removed retroactively from 1 January 2025. It is not the family office number.

The family office numbers, from paragraphs 4.3 to 4.5 of the circular, are these. A 13O or 13OA SFO fund must have at least S$20 million of AUM in Designated Investments at the point of application and at the end of each basis period, and be managed by an SFO employing at least 2 qualifying investment professionals, of whom at least one is not a family member. A 13U SFO fund must have at least S$50 million on the same test, with 3 professionals on the same non-family condition. There is a hiring runway: a 13O applicant may apply with one qualifying professional and must reach two, one of them non-family, by the end of the first year of assessment's basis period — failing which the award is revoked back to its commencement date. Investment professionals must be Singapore tax residents earning more than S$3,500 a month and engaged substantially in fund management.

The running conditions are where the real cost sits. Tiered minimum local spending, measured on AUM in Designated Investments at the end of the basis period: S$200,000 below S$250 million; S$500,000 from S$250 million to under S$2 billion; S$1,000,000 at S$2 billion and above. The capital deployment requirement is to invest the lower of 10% of AUM in Designated Investments or S$10 million into three streamlined options, with a 2x multiplier for equities listed on approved exchanges. And one footnote decides more family cases than all of the above: the fund's investment in the operating businesses of the family cannot be counted towards the minimum AUM in Designated Investments. The company that is most of the family's wealth does not count towards the floor.

The second question: at what size is a single family office economic?

There is no official figure, and this page will not invent one. MAS publishes qualifying conditions for a tax incentive, not a viability threshold for a business, and the vendor pages that answer this question with a confident all-in cost are quoting themselves. What can be stated honestly is which of the published conditions are costs rather than tests: two or three salaried investment professionals who must be Singapore tax residents paid above the stated monthly floor and substantially engaged in fund management; a minimum local spend of at least S$200,000 in each basis period even at the smallest tier; audited compliance reporting at application and at each basis period end; and capital locked into deployment options that are chosen for Singapore's economy rather than for the family's return.

The state does publish one figure that reads as its own view of scale, in a different programme. Under the Economic Development Board's Global Investor Programme, factsheet updated 5 May 2025, Option C requires the applicant to establish a Singapore-based single family office with assets under management of at least S$200 million, of which at least S$50 million must be transferred into Singapore and deployed in equities listed on Singapore approved exchanges, no later than 12 months from the final approval of permanent residence and maintained thereafter. That is a residency route, not a viability test — but it is the size at which Singapore's own investment agency treats a family office as an anchor worth granting residence for, and it sits an order of magnitude above the tax-incentive floor.

The third question: does the family need one at all?

A family office is a management structure; the 13O and 13U schemes are a tax wrapper around a fund it manages. If the problem the family is actually trying to solve is who decides, who is paid, and what happens the month a founder cannot sign, then a fund structure does not solve it and the incentive is irrelevant to it. A trust settles who holds and who decides — Singapore's Trustees Act 1967 allows a perpetuity period of up to 100 years, and section 90 shields a Singapore trust from foreign forced-heirship claims. A holding company with a real constitution and a shareholders' agreement settles control and exit. A discretionary mandate at a private bank settles portfolio management without any of the above. Each is wrong for someone: a trust for a family unwilling to give up control, a holding company for one whose assets sit in four jurisdictions, a bank mandate for a family whose main asset is an operating business.

None of these structures answer succession by themselves either. A family office does not write a will, and a fund does not decide who inherits shares — the page on who inherits when there is no will in Singapore sets out what section 7 of the Intestate Succession Act 1967 does to a shareholding that nobody documented. Be equally honest about what Singapore does not change: it does not switch off a home country's reach. Taiwan taxes the worldwide estate of its domiciliaries; Thailand has taxed inheritances above THB100m since 2016; Indonesian and Malaysian Muslim estates remain subject to faraid wherever the assets sit. Singapore changes the timing, the governing documents and the professional standard around a settlement. It does not change domicile, and domicile is usually what decides.

How to read any figure you find elsewhere

Four questions will resolve almost every contradiction on this topic. Is the number for an SFO fund or a non-SFO fund? Is it measured at the point of application, or at the end of every basis period? Is it AUM, or AUM in Designated Investments — a distinction that has applied since 1 January 2025, when any reference to a fund's AUM under these schemes became a reference to its AUM in Designated Investments? And what date does the source carry? MAS's own scheme page for family offices carries a publication date of 5 August 2024; the circular that governs new awards is dated 31 July 2026 and revises the spending tiers. Where a page and a later circular differ, the later circular governs. The page on why guides disagree on Singapore's family-office minimum traces the earlier regimes in the same way.

One date belongs in every plan built on these schemes: they expire on 31 December 2029. The circular states that the Government will review them before then to determine whether they are extended or refined, and that funds already awarded an exemption as at 31 December 2029 continue to enjoy it for the life of the fund, provided they keep meeting the conditions in each basis period. That is a genuine planning fact rather than an urgency device — a family weighing a structure in 2027 is weighing whether to be inside the scheme before a review, and a family already inside it is weighing whether its AUM in Designated Investments will still clear the floor at every future basis period end. Both are questions to settle while everyone is alive and every signature is available.
