🇸🇬Section 13O for a Singapore Single Family Office: 2026 Conditions

Section 13O of the Income Tax Act is the workhorse exemption for Singapore single family offices: a Singapore fund company managed by the family's own SFO. The SFO framework has been fixed since 5 July 2023 and remains unchanged as of July 2026 — the tightening in MAS Circular FDD Cir 10/2024 touched non-SFO funds only.

The concept

The fund company's specified income from designated investments is exempt from tax; the vehicle is managed by the family's private SFO. The award is granted by MAS after a preliminary submission to the Financial Development Department and carries conditions for the whole incentive period. The 13D/13O/13U schemes run until 31 December 2029 (MAS). How 13O compares with 13U and offshore 13D — see the scheme overview.

Thresholds and the team

AUM: at least S$20 million in designated investments — at submission and throughout the incentive period. The grace period for building up AUM was abolished on 5 July 2023, so the threshold cannot be reached after filing. If AUM dips below S$20m, the exemption is unavailable for that basis period and resumes the next period once conditions are met again (MAS FAQ).

Investment professionals: minimum two, at least one from outside the family. An IP is a portfolio manager, research analyst or trader earning above S$3,500 a month, spending more than half their time on qualifying activity and remaining a Singapore tax resident throughout. Operations, administration and finance roles — budgeting, cashflow monitoring, document and tax support, order entry — do not count. Qualification is shown by a relevant degree, certification (CMFAS, CFA) or investment-management / M&A experience.

The immigration layer: EP for the team, ONE Pass for the principal

The IP tax-residency requirement has an immigration dimension: for a foreign hire, the investment professional role at the SFO in practice means an Employment Pass at the office itself — MAS expects the declared IPs to sit in Singapore, not advise remotely. MOM's bar for financial services: fixed salary from S$6,200 a month (rising with age to S$11,800; the entry level moves to S$6,600 from January 2027) plus at least 40 COMPASS points (MOM); at S$22,500+ a month the candidate is exempt from COMPASS altogether. For a non-family IP the points usually come from C1 (salary against the sector benchmark) and C2 (qualifications). A principal with a documented income of S$30,000+ a month can take the ONE Pass instead — a personal pass not tied to a single employer (MOM). The full map of statuses — in the residency article.

Spending and capital deployment

The Tiered Spending Requirement tracks AUM: under S$50m → at least S$200K per year of assessment; S$50–100m → S$500K; S$100m and above → S$1m. Within any tier at least S$200K must be local business spending; above that, eligible donations to Singapore charities and blended-finance grants count, with grants recognised at 2x.

The Capital Deployment Requirement: invest the lower of 10% of AUM or S$10 million across six categories — equities/REITs/ETFs listed on MAS-approved exchanges, Qualifying Debt Securities, non-listed funds distributed by licensed FIs, stakes in non-listed Singapore operating companies, climate-related investments, blended finance structures. Multipliers soften the burden: 2x for SG-listed equities and deeply concessional capital, 1.5x for ETFs and funds mandated on SG-listed equities.

A separate condition is a private banking account with a MAS-licensed financial institution — at submission and throughout the period.

The SFO's own tax position

The 13O exemption covers the fund company, not the manager: the SFO itself is an ordinary Singapore taxpayer, and its management fee from the fund bears corporate income tax at 17% (IRAS). Fund and office are related parties, so the fee must be arm's length: IRAS expects independent-level pricing in related-party dealings and transfer pricing documentation above the thresholds. The standard construct is cost-plus: the SFO recharges its operating costs to the fund with a mark-up, and for routine support services IRAS accepts a 5% mark-up without benchmarking (IRAS). The practical point: the office's tax base is the mark-up, not the family's assets, so the 17% is rarely material — the real risk is a token fee that fails the arm's length test.

PTIS: a deduction for overseas philanthropy

Since 1 January 2024 families on 13O/13U have had a philanthropic add-on — the Philanthropy Tax Incentive Scheme. A qualifying donor — one whose 13O/13U fund is managed by a qualifying SFO — claims a 100% tax deduction for overseas donations made through qualifying local intermediaries, capped at 40% of the donor's statutory income (MAS, Budget 2023). The intermediary is local: a registered charity with a foreign fundraising permit, a grantmaker under the MCCY scheme or another MAS-approved structure. In return MAS wants substance on top of the baseline: a philanthropy professional (in-house or contracted), one more local professional hire and an additional S$200K of local business spending. The scheme is built for a sustained giving programme, not a one-off donation.

Process and timeline

The path: preliminary submission → review by the FO team at the Financial Development Department → award. Material changes — UBOs, IPs, structure — must be notified to MAS in writing. Since July 2025 MAS has targeted processing complete SFO applications within 3 months, against more than 12 months previously (Hubbis).

The checklist: fund company + SFO → private banking account → S$20m in designated investments before filing → two IPs (one non-family) → preliminary submission → after the award, annual MAS and IRAS filings.

Since mid-2023 source of wealth has been the least predictable stage of an application. The check runs in two layers: the private bank opening the mandatory account verifies UBOs and source of wealth and funds, while MAS screens applicants against money-laundering, terrorism-financing and adverse-news databases and tests the legitimacy of the structure itself (MAS). From 1 October 2024 an independent screening report from a MAS-approved provider adds a third layer, covering a wider circle of connected persons and entities (Rajah & Tann). The standard pack: audited accounts of the source business, sale and purchase agreements for exits, tax returns, statements tracing the chain of funds. The longer the chain from the original business to investable assets, the further FDD drifts past the three-month target. Sanctions exposure is a sensitivity of its own — it draws the deepest scrutiny, up to parliamentary questions about awards already granted (MAS, 2025). How to assemble the file — in the source-of-funds article.

Who it suits

Families with liquid capital from roughly S$20 million prepared for real substance: S$200K+ of local spending a year, a non-family hire, CDR investments into the Singapore market. It does not suit portfolios heavy in non-DI assets — crypto, art, Singapore property — which do not count towards the threshold. Capital well below S$20m is left with non-SFO tracks starting at S$5m, which mean a fund with an external manager rather than a family construct.
