Singapore’s two flagship family office tax incentives — Section 13O and Section 13U of the Income Tax Act — sit at the heart of the Lion City’s offering to global wealth. They look similar on paper: both provide an exemption from Singapore income tax on specified investment income, both are administered by the Monetary Authority of Singapore (MAS), and both require setting up a Singapore-resident family office structure. Yet they target very different families, carry very different cost bases, and have diverged sharply in 2026 as MAS continues to tighten enforcement and raise economic substance requirements.
This guide unpacks the differences in plain English: who each incentive is really for, what you must commit to, and how the costs and constraints compare in 2026.
The Architecture: Why Singapore Offers Two Schemes
Section 13O (formerly Section 13R) and Section 13U (formerly Section 13X) both exempt income arising from “designated investments” managed by a Singapore-based family office. The exemption covers a broad list — listed securities, qualifying bonds, futures, options, certain private investments, and (with conditions) digital assets.
The two schemes exist because they cater to different family profiles:
- Section 13O — designed for medium-sized family offices with a clear Singapore foothold. The fund must be incorporated and resident in Singapore. The minimum thresholds are lower.
- Section 13U — designed for larger, more institutionalised family offices. The fund can be a Singapore or foreign-incorporated vehicle, but managed out of Singapore. Higher thresholds; greater flexibility on legal form.

Section 13O: The “Onshore Fund” Tax Incentive
Section 13O applies to a Singapore-incorporated and tax-resident fund vehicle. Updated MAS thresholds for new applications submitted in 2026 are:
| Requirement | Section 13O |
|---|---|
| Minimum fund AUM at application | S$20 million |
| Minimum AUM at year 2 | S$50 million |
| Annual local business spending | S$200,000 (Tier 1) to S$1 million (Tier 3, depending on AUM) |
| Investment professionals (IPs) in Singapore | At least 2 (at least 1 non-family member) |
| Capital deployment in Singapore investments | At least 10% of AUM or S$10m (whichever is lower) |
| Fund legal form | Singapore company (or VCC sub-fund) |
| Fund tax residence | Singapore |
Section 13O has historically been the entry point for families with S$20–S$100 million in investable assets. The lower thresholds make it attainable for first-generation entrepreneurs from the region.
Section 13U: The “Enhanced Fund” Tax Incentive
Section 13U is for larger, more institutional family offices and supports a wider range of structures — including foreign-incorporated funds managed from Singapore.
| Requirement | Section 13U |
|---|---|
| Minimum fund AUM at application | S$50 million |
| Annual local business spending | S$500,000 (Tier 1) to S$1.5 million (Tier 3, depending on AUM) |
| Investment professionals (IPs) in Singapore | At least 3 (at least 1 non-family member) |
| Capital deployment in Singapore investments | At least 10% of AUM or S$10m (whichever is lower) |
| Fund legal form | Singapore or offshore |
| Fund tax residence | Singapore or offshore (if managed from Singapore) |
Section 13U is preferred by families with substantial existing offshore holdings — typically Cayman, BVI, or Jersey vehicles — that they do not wish to redomicile. The Singapore-based family office manages those offshore funds and the exemption flows through.
Side-by-Side Comparison
| Factor | Section 13O | Section 13U |
|---|---|---|
| Suitable for | Mid-size families S$20–100m | Larger families S$50m+ or with existing offshore funds |
| Fund vehicle | Singapore company / VCC | Singapore or offshore |
| Minimum IPs | 2 (1 external) | 3 (1 external) |
| Application process | MAS direct | MAS direct |
| Typical processing time | 6–9 months | 9–12 months |
| Annual operating cost | S$600k–S$1.2m | S$1.2m–S$3m+ |
| Charitable giving requirement | 0.5%–1% of AUM annually (philanthropy expectation) | 0.5%–1% of AUM annually |
The 2022 and 2024 Tightenings — Why Today’s Bar Is Higher
In April 2022, MAS introduced significantly tighter requirements for new Section 13O and 13U applications, raising thresholds for AUM, IPs, local spending, and Singapore-deployed capital. In 2024, MAS introduced a tiered framework for local business spending — the higher your AUM, the more you must spend locally each year.
The intent: ensure family offices contribute economic substance to Singapore, not just register a name plate. In 2026, MAS continues to apply substance scrutiny — annual returns must demonstrate genuine local activity, philanthropic contributions, and ongoing Singapore deployment.
The Investment Professional Requirement — Often Underestimated
One of the most common stumbling blocks is the IP requirement. An “investment professional” must be:
- A senior portfolio or investment decision-maker (not back office)
- Working full-time from Singapore
- Earning a market-rate compensation (typically S$120,000+ per year as a guide)
- For at least one IP under both schemes: not a member of the beneficial-owning family
The “non-family” IP is the rub. Hiring an external investment professional with track record and willingness to relocate to Singapore — often from Hong Kong, London, or Switzerland — is the single biggest line item in family office setup. We see compensation packages of S$300,000–S$500,000+ for the lead IP at established family offices.
Local Capital Deployment Requirement
Both schemes require at least 10% of AUM (or S$10 million, whichever is lower) deployed into specified Singapore investments. This includes:
- Equities listed on the Singapore Exchange (SGX)
- Singapore Government Securities (SGS) and Singapore-issued bonds
- Funds managed by Singapore-based managers
- Direct investments into Singapore-domiciled private companies
For a S$50 million fund, that’s at least S$5 million parked in Singapore-eligible assets. Not punitive in absolute terms, but a real constraint for families whose portfolios are concentrated outside the region.
Application Process
Step 1 — Pre-application engagement. MAS conducts informal discussions with the prospective family office to gauge fit. Engage MAS via your corporate services advisor or directly through the Family Office Development Team.
Step 2 — Formal application. The fund manager (typically the single family office company) submits an application to MAS detailing the fund structure, investment policy, IP hiring plan, AUM, beneficial ownership, and AML/CFT framework.
Step 3 — MAS review and queries. Iterative process; expect 2–3 rounds of follow-up. The fund must be incorporated and capitalised before MAS issues conditional approval.
Step 4 — Conditional approval. MAS issues a letter setting out the approval conditions: minimum AUM, local spending, IP recruitment timeline, and reporting obligations.
Step 5 — Implementation. Fund deploys capital, IPs are onboarded, local operations commence. Approval becomes effective from the basis period in which conditions are met.
Step 6 — Annual reporting. Each year, the family office submits a report demonstrating ongoing compliance with all conditions.
Costs of Establishing and Running
| Cost Item | Indicative Annual Range |
|---|---|
| Legal setup and MAS application | S$80,000–S$200,000 (one-off) |
| Corporate services (secretarial, accounting, tax) | S$30,000–S$80,000 annually |
| Investment professional compensation | S$300,000–S$1,000,000+ for the lead IP |
| Support staff (admin, compliance) | S$120,000–S$300,000 |
| Office space (mandatory physical office) | S$80,000–S$200,000 |
| Audit and statutory filings | S$15,000–S$40,000 |
| Custody and execution costs | Variable, basis points on AUM |
| Tax and regulatory advisory | S$30,000–S$80,000 |
Total: S$600,000–S$3,000,000+ annually depending on AUM and scheme. The economics make sense when fund returns on a S$50–500m portfolio outweigh these costs — typically the case for families serious about consolidating wealth in Singapore.
Which Scheme Should You Choose?
A simple decision framework:
- If AUM is S$20–50 million: Section 13O is your only real option.
- If AUM is S$50–100 million and assets are mostly held in Singapore-eligible vehicles: Section 13O is usually cheaper to run.
- If AUM is S$50+ million with substantial existing offshore funds (Cayman, BVI): Section 13U is preferable — you preserve the offshore structure.
- If AUM is S$200+ million and you plan multiple sub-funds with different family branches: Section 13U with a Singapore VCC umbrella is the most flexible.

Common Mistakes Families Make
- Underestimating IP hiring costs. A capable external IP is a S$300k+ annual commitment.
- Treating Singapore deployment as optional. The 10% / S$10m floor is a hard rule. Plan for it.
- Drifting on local business spending. Each year you fall short, MAS sends a query. Repeated shortfalls trigger withdrawal of incentive.
- Forgetting AML/CFT. Family offices are obligated persons under the AML regime. Setting up the framework retroactively is painful.
- Choosing the wrong scheme for the structure. Putting an offshore Cayman fund under Section 13O fails — that’s a Section 13U case.
