Section 13O vs 13U: Comparing Singapore’s Family Office Tax Incentive Schemes

Singapore has cemented its position as Asia’s leading wealth management hub, and at the centre of that story sits the Single Family Office (SFO). For wealthy families looking to consolidate global investment activity in a stable, tax-efficient jurisdiction, the two tax incentive schemes offered under Section 13O and Section 13U of the Income Tax Act 1947 are the linchpin of any serious structuring conversation.

Raffles Corporate Services works with a panel of experienced Singapore law firms who offer cost-effective and efficient legal service and advice. This article is general information only and is not legal advice.

The two schemes do similar things — they grant Singapore tax exemption on “specified income” derived from “designated investments” — but they are calibrated for very different sizes and styles of family wealth. Choosing the wrong scheme can mean either committing to operating costs that the family does not need, or losing scheme eligibility because the family is already too big for the entry-tier rules. This guide unpacks the differences in plain language so that founders, principals and advisers can make a clear-eyed call on which incentive fits.

What 13O and 13U Actually Exempt

Both Section 13O and Section 13U exempt the qualifying fund vehicle (managed by the family’s Singapore-based fund manager, i.e. the SFO) from Singapore income tax on a defined list of “specified income” derived from “designated investments”. In practice this captures most of what a sophisticated investor would hold: listed and unlisted equities, debt securities, derivatives, collective investment schemes, real estate (subject to conditions), commodities, foreign exchange, and qualifying private equity and venture capital interests.

Importantly, the exemption attaches to the fund vehicle, not to the family office itself. The fund vehicle is typically a Singapore-incorporated private limited company or, increasingly, a Variable Capital Company (VCC) sub-fund, while the SFO sits alongside it as the licensed-exempt fund manager.

Section 13O at a Glance

Section 13O — sometimes called the “Onshore Fund Tax Exemption” or the entry-tier scheme — is the workhorse of Singapore’s family office regime. It is administered by the Monetary Authority of Singapore (MAS) and applies to funds that are Singapore tax resident.

The 2025 refresh of the qualifying conditions raised the bar significantly. As at the date of this article, the headline requirements for a Section 13O Single Family Office fund are:

• Minimum AUM: S$20 million at the point of application, with no grace period to build up to that level.
• Investment Professionals (IPs): At least two. If only one IP is in place at application, a 12-month grace period applies to hire the second.
• IP qualification: Each IP must earn a minimum fixed monthly salary of S$3,500, be Singapore tax resident, and hold genuine investment responsibilities (not simply be on the payroll).
• Local Business Spending (LBS): Tiered. A minimum of S$200,000 per annum where AUM is below S$50 million, rising as the fund grows.
• Capital Deployment Requirement (CDR): At least 10% of AUM or S$10 million (whichever is lower) to be invested in Singapore-based investments at all times.
• Vehicle: A Singapore-incorporated company that is a Singapore tax resident.

Section 13O is the right starting point for families who want a meaningful Singapore presence but who do not yet need (and do not yet wish to fund) the headcount and spend profile of a 13U platform.

Section 13U at a Glance

Section 13U — also known as the “Enhanced-Tier Fund Tax Incentive” — is the premium tier. It accommodates larger and more sophisticated structures, including master-feeder arrangements, and applies to both onshore and offshore funds. Critically, a 13U fund vehicle is not required to be Singapore tax resident, which gives advisers more flexibility on cross-border structuring.

The headline requirements are tougher across the board:

• Minimum AUM: S$50 million at the point of application, maintained on an ongoing annual basis.
• Investment Professionals: At least three IPs, of whom at least one must not be a family member.
• IP qualification: Same baseline of S$3,500 fixed monthly salary, Singapore tax residency and genuine investment work.
• Local Business Spending: Tiered, starting at S$500,000 per annum for funds in the S$50–100 million range, rising to S$1 million per annum for funds above S$100 million.
• Capital Deployment Requirement: Same 10% / S$10 million floor as 13O.
• Vehicle: Singapore-incorporated company, limited partnership, trust or VCC; not required to be Singapore tax resident.

13U is designed for families who already operate at scale and who want institutional-grade flexibility — multi-fund segregation, layered investor classes, and the ability to bring in trusted non-family investment talent.

The Real-World Cost Difference

Headline criteria are only half the story. The bigger consideration for principals is the operating cost of running a compliant scheme over time. Three line items dominate:

1. People

A Section 13O office can technically be run with two IPs — a CIO-equivalent and an analyst, for example. A Section 13U office needs three, and one of those must be unrelated to the family. Singapore’s market rate for an experienced buy-side analyst comfortably runs into six figures, and a non-family CIO with verifiable institutional pedigree commands considerably more. This drives the bulk of the cost gap between the two tiers.

2. Local Business Spending

LBS captures spend on Singapore-based service providers — corporate secretarial, audit, fund administration, tax, registered office, legal counsel, technology and similar. A 13O fund just under the S$50 million LBS step pays a minimum of S$200,000 per annum. A 13U fund of the same size sits at S$500,000. Once AUM crosses S$100 million, the 13U LBS rises to S$1 million per annum.

3. Compliance and reporting

Both schemes require annual returns to MAS, audited fund accounts, statutory filings to ACRA and corporate tax filings to IRAS. The complexity of a 13U platform — particularly when structured as a master-feeder or VCC umbrella — drives higher audit and fund administration fees. The annual AGM requirements for Singapore companies apply to the fund vehicle just as they do to any operating company.

As a rough yardstick, a typical 13O SFO operates at S$300,000–S$700,000 per annum all-in, while a typical 13U platform sits at S$700,000–S$1.5 million per annum. The 13U cost looks heavy in absolute terms, but spread across a larger AUM base it can be very economical on a per-million-managed basis.

Which Scheme Should You Choose?

The decision usually comes down to a small number of practical questions. The honest answer is that very few families end up agonising over the choice once these are addressed.

Is the family’s investible AUM at S$50 million or above?

If yes, 13U is on the table. If no, 13O is the only realistic entry point.

Will the fund hold offshore vehicles or feeder structures?

If you need the fund vehicle to sit outside Singapore, or you want to use a trust or LP wrapper, 13U is the only option. 13O requires a Singapore tax resident fund vehicle.

Are you willing to bring in a non-family IP?

13U requires it. Many families resist the idea of sharing investment decision-making with an outsider, in which case 13O is the more comfortable home.

Is residency / Permanent Residence a goal for the principal?

Section 13U dovetails with the EDB-administered Global Investor Programme (GIP), particularly the family office route, which requires a S$200 million AUM SFO with at least S$50 million invested in EDB-approved categories. If the principal wants Singapore PR through the family office track, they will end up at 13U whether or not the tax position alone would have demanded it.

Common Pitfalls We See

Even sophisticated families make avoidable mistakes when navigating the schemes. The recurring ones are worth flagging:

• Treating the IP requirement as cosmetic. MAS now scrutinises whether IPs are doing genuine investment work. Padding a job description, paying below-market salaries, or appointing the family’s general counsel as the “IP” will not survive review.
• Underestimating the Capital Deployment Requirement. The 10% / S$10 million Singapore deployment floor is a continuous condition. Drift below it — for example after a large overseas redemption — and the exemption can fall away.
• Confusing the SFO with the fund. The fund holds the assets and claims the exemption. The SFO is the manager and bills the fund. Founders sometimes try to collapse the two and end up creating tax inefficiencies that defeat the point of the structure.
• Forgetting ACRA basics. Whatever tier you choose, the underlying Singapore company must comply with the Companies Act 1967 — registered office, qualified company secretary, statutory registers, annual returns. Our Singapore company compliance checklist sets out the full picture.

Documentation You Will Need

The MAS application pack is detailed but not unmanageable. Expect to assemble: source-of-wealth documentation for the principal(s), a structure chart showing the SFO and fund vehicle, audited financials for the family’s investible assets, an investment policy statement, projected LBS and IP hiring plan, board resolutions for the SFO and fund vehicle, and supporting directors’ resolutions in writing for the relevant approvals. Tax filings with IRAS follow the usual corporate calendar, and ACRA registrations are made via BizFile+.

Conclusion

Section 13O and Section 13U are not really competing schemes — they are complementary tiers in a single framework, designed to scale with the family. 13O is right for the family that is committing meaningfully to Singapore for the first time and wants a clean, manageable platform. 13U is right for the family whose AUM, ambition or residency plans demand a larger institutional footprint.

The right answer for any specific family depends on AUM, governance preferences, the openness to bringing in non-family investment talent, and longer-term residency goals. Getting that diagnosis right at the start is what separates a family office that runs smoothly for decades from one that has to be restructured (expensively) within three years.
