Family Office Rule SEC vs MAS: Family Clients, Key Employees and Third-Party Money

By VCC Editorial Team · Published 15 October 2026 · Updated 16 October 2026

Short answer: The SEC takes a qualifying family office outside the Investment Advisers Act altogether, so it files nothing under that Act. MAS exempts a qualifying single family office from licensing as a class, in return for a notice of commencement within 14 days of starting and an annual return within four months of each financial year end.

For a family running an office in New York beside one in Singapore, the family office rule SEC vs MAS comparison decides whether each office can stay outside licensing. Both regulators start from the same premise, that an office managing one family’s money needs no investor protection rules, and then draw the boundary in different places. Below, the definitions of family, key employee and third-party money are compared clause by clause, with what each regulator receives and where a structure passing one test fails the other.

This article is general information only and is not legal, tax or immigration advice. For matters needing legal advice, we work with a panel of experienced Singapore law firms.

What does each regime actually exempt the family office from?

The SEC rule removes a qualifying family office from the definition of investment adviser, so the Advisers Act does not apply to it at all. The MAS framework leaves the SFO carrying on regulated fund management, but exempts it from holding a capital markets services licence if it meets fixed conditions and files with MAS.

The difference is structural. Under 17 CFR 275.202(a)(11)(G)-1, paragraph (a), a family office “shall not be considered to be an investment adviser” for the purposes of the Act. The SEC’s summary of Release IA-3220 says such offices “will not be subject to regulation under the Advisers Act”. The exclusion came from the Dodd-Frank Act, which repealed the private adviser exemption most family offices had relied on and directed the SEC to define family offices instead. If an office falls outside the rule, the SEC’s compliance guide treats registration or an exemptive order as the alternative.

Singapore took the opposite route. MAS’s FAQs on the licensing exemption framework for single family offices (issued 12 June 2026, updated 31 July 2026) describe a structure-agnostic class exemption from licensing under the Securities and Futures Act 2001. MAS says it will generally not grant case-by-case exemptions “unless there are exceptional reasons”, and FAQ 13 confirms that an SFO can no longer fall back on the related-corporation exemption in paragraph 5(1)(b) of the same Schedule. For the mechanics of the Singapore filing itself, see our guide to the 2026 SFO licensing-exemption notice.

How do the family office rule SEC vs MAS definitions of family compare?

Both start with the lineal descendants of a common ancestor, but the SEC reaches 10 generations and includes cohabiting partners, while MAS reaches five generations and turns on whether a relationship is legally recognised.

Under paragraph (d)(6) of the SEC rule, a family member is any lineal descendant of a common ancestor (including adopted, step and foster children and certain wards) and their spouses or spousal equivalents, provided the common ancestor is no more than 10 generations removed from the youngest generation. A “spousal equivalent” is “a cohabitant occupying a relationship generally equivalent to that of a spouse”. Former family members (spouses, spousal equivalents and stepchildren who left the family through divorce or a similar event) remain family clients.

MAS FAQ 2 defines a family member as all lineal descendants of a common ancestor, including current or former spouses, adopted children, stepchildren, parents-in-law and siblings-in-law. The ancestor must not be more than five generations removed from the youngest generation that established the SFO in Singapore; once the SFO exists, later generations can be served. The July 2026 update adds that family status is generally based on whether the relationship is legally recognised, in Singapore or in the individual’s own jurisdiction. The definition sits in paragraph 5(1AF) of the Second Schedule.

Point	SEC family office rule	MAS SFO class exemption
Generational reach	Common ancestor no more than 10 generations from the youngest generation	Common ancestor no more than five generations from the youngest generation that set up the SFO; later generations may then be served
Unmarried partners	Included as “spousal equivalents” if cohabiting in a spouse-like relationship	Depends on legal recognition in Singapore or the individual’s jurisdiction
In-laws	Spouses of lineal descendants; no separate in-law category	Parents-in-law and siblings-in-law expressly listed
Former spouses	Former family members remain family clients	Former spouses expressly included
Charities	Funded exclusively by family clients (which include key employees)	Funded exclusively by the family
Trusts and companies	Specified trusts, estates and companies wholly owned by and for family clients	Family trusts and corporations wholly owned by, and for the sole benefit of, the family

Where do key employees fit under each test?

Both regimes let an office manage money for its senior staff, but the SEC adds a 12-month experience condition and no size cap, while MAS adds a 10% cap and no experience condition.

The SEC defines a key employee in paragraph (d)(8) as an executive officer, director, trustee, general partner or person in a similar role of the family office or an affiliated family office, or any other employee (not solely clerical, secretarial or administrative) who participates in the office’s investment activities and has done that work, for the office or in a substantially similar role elsewhere, for at least 12 months. It extends to a spouse or spousal equivalent holding a joint or community property interest with the key employee.

MAS FAQ 1 lists key employees as executive directors, the chief executive officer, the chief financial officer and investment professionals. Assets from key employees who are not family members must not exceed 10% of the SFO’s assets under management in aggregate, and those key employees may own a non-controlling stake of up to 10% in the SFO.

Departure is treated differently. Under the SEC rule, a former key employee may keep assets already advised and honour prior commitments, but may not add new assets. Under MAS FAQ 12 (added July 2026), a key employee who leaves must divest both their shareholding in the SFO and any investments it manages within one year of ceasing employment.

How much third-party money can each office manage?

Neither office may take outside clients. The SEC tolerates a non-family client only for one year after a death or other involuntary transfer; MAS tolerates non-family money only from key employees within the 10% cap.

The SEC rule requires that the office have “no clients other than family clients”. If a non-family person becomes a client through the death of a family member or key employee, or another involuntary transfer, that person is treated as a family client for one year after legal title passes. The office must also be wholly owned by family clients, exclusively controlled by family members or family entities, and must not hold itself out to the public as an investment adviser.

MAS states the policy plainly in FAQ 5: SFOs are not licensed because they manage their own assets or those of the same family, unlike licensed managers that manage “monies for third-party customers”. The funding of the SFO must come exclusively from family members, directly or indirectly, and from qualifying key employees. An office that starts taking money from friends, co-investors or a second family moves into licensed territory; our note on when an SFO crosses the licensing line covers that boundary.

What does each regulator receive from the family office?

The SEC receives nothing under the Advisers Act from an excluded office. MAS receives a notice of commencement, a signed declaration and an annual return each year.

In Singapore the sequence for a new SFO, drawn from MAS FAQs 1, 3, 6, 7 and 9 to 11, runs as follows.

1. Incorporate the SFO in Singapore; it may be held through a trust, foundation or any other legal structure.
2. Open bank accounts for the SFO and each investment vehicle it manages with a MAS-licensed bank. A foreign-incorporated vehicle may instead bank with a regulated bank in a jurisdiction whose AML/CFT rules meet Financial Action Task Force standards. Accounts must be open first, because the notice asks for the bank details.
3. Obtain the declaration signed by a family member who provided the assets and a director of the SFO (one signature suffices if that person is both). A service provider may file using its own Corppass account but cannot sign the declaration.
4. File the notice of commencement within 14 days of starting operations. No legal opinion is required, and MAS issues a system-generated acknowledgement.
5. File the annual return, covering total assets under management and the name of the bank, within four months of each financial year end. MAS says no further extension will be granted.

Under FAQ 8 there is no duty to update MAS on later changes to shareholding or operational arrangements, although 13O, 13OA and 13U tax incentive conditions are separate and may require notification. An SFO that was operating before 15 June 2026 has until 15 June 2027 to comply and notify; our article on the 15 June 2027 transition deals with offices that do not yet fit.

In the US, the excluded office files no registration and no Advisers Act reports, but other federal reporting still applies. The SEC’s Form 13F FAQ states that a manager exercising investment discretion over US$100 million or more in Section 13(f) securities must file Form 13F “regardless of whether it is an SEC-registered investment adviser”, and that foreign managers using US interstate commerce are caught on the same terms.

Item	US (SEC)	Singapore (MAS)
Legal effect	Outside the definition of investment adviser	Exempt from capital markets services licence for fund management
Registration or notice	None under the Advisers Act	Notice of commencement within 14 days of starting operations
Periodic return	None under the Advisers Act	Annual return within four months of financial year end
Place of incorporation	No condition in the rule	Must be incorporated in Singapore
Bank account condition	None in the rule	MAS-licensed bank for the SFO and its vehicles (foreign vehicles: FATF-compliant jurisdiction permitted)
Control	Exclusively by family members or family entities	Non-family key employees limited to a non-controlling stake of up to 10%
Fallback if conditions fail	Registration or an SEC exemptive order	Case-by-case exemptions generally not granted

Where can a structure pass one test and fail the other?

Most mismatches involve staff, partners and leavers, because the definitions of key employee and family member do not line up.

• A newly hired analyst who co-invests from day one is a key employee for MAS, but under the SEC rule only becomes one after 12 months in a qualifying investment role.
• A portfolio manager’s personal allocation is uncapped in the US, but in Singapore non-family key employee assets must stay within 10% of assets under management in aggregate.
• An unmarried partner who cohabits with a family member is a family client in the US, but in Singapore qualifies only if the relationship is legally recognised.
• A departing executive may keep existing investments with the US office, but must exit the Singapore SFO within one year.

How should a family run a New York office beside a Singapore one?

Treat the two offices as separate persons, each tested against its own rule, and set shared policies to the stricter standard on each point.

1. Map every client, investor and shareholder of each office against both definitions, and record the common ancestor and generation count used for each.
2. Set a single co-investment policy for staff that applies the SEC’s 12-month condition and the MAS 10% cap together.
3. Keep family control of both offices. The SEC requires exclusive control by family members or family entities; a non-family stake in the Singapore SFO must stay non-controlling and within 10%.
4. Diary the Singapore annual return four months after each financial year end, and the 14-day notice for any new SFO entity.
5. Check whether either office, alone or with the other, exercises discretion over US$100 million or more in Section 13(f) securities, which triggers Form 13F whatever its adviser status.
6. Avoid public marketing language in either office. Holding out to the public as an investment adviser is a stated SEC disqualifier.

The US rule also recognises an “affiliated family office”, wholly owned by family clients of another family office, controlled by its family members or affiliated family entities, and serving only those clients. Whether a Singapore SFO can be treated that way, and any other US question raised by advising US-resident family members, is for US counsel. Tax runs separately: see our article on US estate tax for Singapore residents, and the hub choice in our eleven-hub scorecard. Singapore incorporation and corporate secretarial support for the SFO entity is available through Raffles Corporate Services.

Frequently asked questions

Does a US family office have to register with the SEC?

No, not if it meets Rule 202(a)(11)(G)-1. A qualifying office is not an investment adviser under the Advisers Act, so there is no registration or Advisers Act filing. Other SEC reporting, such as Form 13F, can still apply.

What must a Singapore SFO file with MAS?

A notice of commencement within 14 days of starting operations, with a declaration signed by a contributing family member and a director, and an annual return within four months of each financial year end stating total assets under management and the bank used.

Can a key employee own shares in the family office?

In Singapore, a non-family key employee may hold a non-controlling stake of up to 10%. Under the SEC rule, key employees are family clients and may be owners, but control must rest exclusively with family members or family entities.

Does a Singapore SFO need a legal opinion to rely on the exemption?

No. MAS FAQ 10 states there is no requirement to seek legal advice or furnish a legal opinion with the notice, although the SFO must be able to satisfy every condition before it files.
