Section 13O vs 13U: Comparing Singapore Family Office Tax Incentives

Singapore offers two parallel tax-exemption schemes for fund vehicles managed by family offices: Section 13O and Section 13U of the Income Tax Act 1947. Both schemes shelter “specified income” derived from “designated investments” from Singapore tax — but they target different sizes of family wealth and impose meaningfully different conditions on assets, hiring, spending, and capital deployment.

For families relocating to Singapore in 2026, picking the wrong scheme is an expensive mistake. Apply for 13U when you only have S$30 million on the table and you’ll be denied. Apply for 13O when you’ve already earmarked S$80 million and you may have left a more flexible regime on the table. This guide walks through what each scheme requires, how they differ on the specifics that matter most, and which scheme suits which family profile.

If you are still in the earlier stages of considering Singapore, our Singapore Family Office Setup Guide 2026 covers the broader structuring choices before you reach the tax-incentive stage.

What Sections 13O and 13U Actually Do

Both schemes sit inside the Income Tax Act 1947 and both produce the same headline outcome: the fund vehicle pays no Singapore tax on dividends, interest, and gains derived from “designated investments”. Without the exemption, those returns would be taxed at the standard 17% corporate rate.

The exemptions are administered by the Monetary Authority of Singapore (MAS), which screens each application against published criteria. Approval is not automatic — applicants must demonstrate substance in Singapore, deploy a portion of their capital locally, and keep MAS updated on an annual basis.

Section 13O applies to fund vehicles that are themselves Singapore tax residents (typically a Singapore-incorporated company or a sub-fund of a Variable Capital Company). Section 13U is more permissive on legal form — the fund can be Singapore-resident or offshore — but is calibrated for larger AUM levels and stricter staffing.

Side-by-Side Comparison: The Headline Numbers

The criteria below reflect the framework as updated by MAS, with the most recent revisions taking effect from 1 January 2025.

The Capital Deployment Requirement applies equally to both schemes and was the most substantive change introduced by MAS’s 2022 framework. It signals that families enjoying tax exemption must visibly contribute to Singapore’s capital markets ecosystem — not just park assets here.

What Counts as “Designated Investments”?

Both 13O and 13U exempt income from a defined list of designated investments. The list is broad and covers most asset classes a sophisticated family office would expect to hold:

• Equities and equity-linked securities (Singapore and global)
• Debt securities, including Singapore Government Securities
• Units in funds and REITs
• Foreign exchange contracts and derivatives
• Commodities derivatives
• Private equity investments and structured products
• Loans extended to non-Singapore tax-resident borrowers (subject to conditions)

Income from operating businesses (e.g., a wholly-owned trading subsidiary) is not “specified income” and remains taxable. Property income from physical Singapore real estate also sits outside the exemption — although income from listed REITs or qualifying property funds qualifies.

Investment Professionals: The Subtle Difference That Trips Families

Both schemes require the family office to employ Investment Professionals (IPs) who are tax-resident in Singapore, earning at least S$3,500 in fixed monthly salary, and holding genuine investment responsibilities (research, portfolio management, deal execution).

13O: minimum 2 IPs, family OK

Under 13O, both IPs may be family members. This is friendly to families where the principal and a son or daughter are both genuinely involved in investment decisions. A 1-year grace period applies if only 1 IP is hired at application — the second must be onboarded within 12 months.

13U: minimum 3 IPs, at least one independent

Under 13U, at least one of the three IPs must NOT be a family member. This effectively forces 13U applicants to hire a non-related portfolio manager, analyst, or head of investments. Non-resident expats hired into this role typically need an Employment Pass, with all the COMPASS scoring implications that brings.

That single requirement is often the deciding factor for families who could financially clear the S$50m AUM bar but prefer to keep the operation tight-knit. They opt for 13O instead, even at slightly higher AUM, to avoid being forced into an external hire.

Local Business Spending: Tiered, but Tiered Differently

Both schemes require minimum Local Business Spending (LBS) — money paid to Singapore-based service providers, employees, and overheads — and both use a tiered structure. The tiers, however, are not the same.

13O LBS tiers

• AUM under S$50 million — at least S$200,000 LBS per year
• AUM between S$50 million and S$100 million — at least S$500,000 LBS per year
• AUM above S$100 million — at least S$1 million LBS per year

13U LBS tiers

• AUM under S$250 million — at least S$200,000 LBS per year
• AUM between S$250 million and S$2 billion — at least S$500,000 LBS per year
• AUM at S$2 billion or above — at least S$500,000 LBS per year (capped tier)

In practice this means a 13U applicant with S$100 million in AUM has a lower LBS floor than a 13O applicant at the same level (S$200,000 vs S$1 million). The trade-off, of course, is the larger entry AUM, the third IP, and the independence requirement.

The Capital Deployment Requirement: The Same for Both

Both schemes oblige the family office to invest the lower of 10% of AUM or S$10 million in eligible local investments. “Eligible” here means:

• Equities, REITs, Business Trusts, or ETFs listed on MAS-approved exchanges (the Singapore Exchange, primarily)
• Qualifying Debt Securities issued in Singapore
• Non-listed funds distributed in Singapore by licensed financial institutions
• Investments in non-listed Singapore operating companies
• Climate-related investments aligned with Singapore’s green finance priorities

A multiplier applies to the climate and unlisted-Singapore-company categories — every dollar deployed there counts as more than a dollar against the capital deployment threshold. Families with strong impact-investing inclinations have found this an efficient way to satisfy the requirement.

Which Scheme Should You Pick?

Pick 13O if:

• Your investible AUM at application is between S$20 million and S$50 million.
• You want the option to staff the family office entirely with family members.
• You’re comfortable using a Singapore-incorporated fund vehicle (or VCC sub-fund).
• You expect AUM to grow into the S$50–S$100 million band over time, but not above the LBS step-up.

Pick 13U if:

• You’re applying with at least S$50 million committed AUM.
• You’re prepared to hire at least one non-family IP (often a Singapore-licensed portfolio manager or analyst).
• You want the option to keep the fund vehicle offshore — typically a Cayman or BVI feeder — while still enjoying Singapore tax exemption.
• Your AUM is likely to scale into the hundreds of millions; the flatter LBS tier saves money at scale.

Application Timeline and Practical Steps

The MAS approval timeline for either scheme runs roughly 6 to 9 months from a complete application, sometimes longer where MAS has substantive follow-up questions on source of funds, beneficial ownership, or the substance of the IP roles.

A typical sequence looks like this:

1. Pre-application structuring — Singapore-incorporated fund vehicle or VCC sub-fund is established, single family office (SFO) is incorporated as the manager, and all KYC/source-of-funds files are assembled.
2. MAS pre-meeting — for 13U applicants and for 13O applicants with sensitive ownership, an informal pre-meeting with MAS is now standard.
3. Submission — full application package goes in via the MAS portal, including biographies of IPs, investment policy statement, and capital deployment plan.
4. MAS Q&A — typically 1–3 rounds of substantive questions over 3–6 months.
5. Approval and implementation — approval letter received; the fund begins to qualify for the exemption from a defined commencement date.
6. Annual reporting — IPs in role, LBS spent, capital deployment maintained, and AUM status reported each year.

Failure to maintain conditions in any year — most commonly slipping below minimum AUM after market drawdowns or losing an IP without immediate replacement — can trigger MAS to withdraw the exemption.

What Happens If You Outgrow 13O?

A family that successfully applies under 13O at S$25 million AUM and grows to, say, S$120 million is not automatically migrated to 13U. The 13O exemption continues so long as conditions are met (including the higher LBS tier of S$1 million once AUM crosses S$100 million). If the family wants to convert to 13U — typically because they want to move the fund vehicle offshore or take on the larger capacity — they apply to MAS for a new approval. A migration of this kind is structurally similar to a fresh application and warrants its own planning timeline.

Common Mistakes

• Applying with hopeful AUM. The S$20 million / S$50 million figures are at the point of application. Pledged but undeployed capital does not count.
• Treating IP roles as nominal. MAS scrutinises whether the IPs are actually doing investment work. Job titles without genuine substance are routinely challenged.
• Underestimating LBS at higher AUM tiers. A 13O fund that grows past S$100 million suddenly faces a S$1 million annual LBS floor — many families don’t budget for the step-up.
• Forgetting the Capital Deployment Requirement. Plenty of families plan their portfolio in global terms and only realise after approval that they need to redirect at least S$10 million (or 10% of AUM) into eligible local investments.
• Missing the family-IP rule under 13U. The “at least one non-family IP” rule for 13U is non-negotiable.

Conclusion

Sections 13O and 13U are not interchangeable wrappers around the same exemption — they sit on a clear spectrum. 13O is the smaller, more flexible-on-staffing scheme for families who want to keep the family office tight-knit. 13U is the larger, more institutional scheme that allows offshore fund vehicles in exchange for stricter hiring and a higher AUM floor. Picking correctly depends on the size of the wealth, the family’s appetite for hiring outside the bloodline, and the long-term ambitions for the fund.

Setting up a Singapore family office under either scheme is a multi-disciplinary exercise — corporate structuring, MAS engagement, immigration for IPs and principals, and ongoing compliance all need to fit together. Raffles Corporate Services regularly advises families on 13O / 13U applications, the supporting fund structures, and the immigration pathways for principals and key staff. We work alongside Singapore tax counsel and licensed fund administrators to deliver an end-to-end family office set-up.
