A fund with a 13O or 13U award keeps its tax exemption only for the years in which it meets the scheme's conditions. This guide sets out those conditions for single-family-office funds, when each is tested, and what happens if one is missed.
It reflects the Monetary Authority of Singapore's (MAS) circular of 31 July 2026, which applies to new awards from 1 August 2026. Section 13OA, in force since January 2025, extends 13O to Singapore limited partnerships on the same terms.
What is checked, and when
Most conditions are now tested at application and then on the last day of each financial year. A few must hold throughout the year.
| Condition | 13O / 13OA | 13U |
|---|---|---|
| Minimum assets in designated investments | S$20 million | S$50 million |
| Investment professionals | 2, at least 1 not a family member | 3, at least 1 not a family member |
| Local investment | Lower of 10% of assets or S$10 million | Same, across the whole structure |
Who counts as an investment professional
A portfolio manager, research analyst or trader who:
- is a Singapore tax resident,
- is paid more than S$3,500 a month, and
- spends more than half of their time on investment work.
Operations, finance, legal and tax roles do not count. A fund may apply one person short. The last hire must be in place by the end of the first year of assessment; if not, the award is revoked from its start date.
Local spending
The amount depends on the fund's assets at year-end.
Local business spending means operating costs paid to parties in Singapore. Taxes, penalties and financing costs do not count. Because the band is set by assets at year-end, a rise late in the year can move a fund into a higher band.
Local investment
At year-end, the fund must hold at least the lower of 10% of its assets or S$10 million in qualifying investments:
- investments listed on approved exchanges;
- investments distributed by MAS-licensed institutions in Singapore;
- unlisted Singapore operating companies with a substantive presence in Singapore.
Some count at twice their value: equities on approved exchanges, funds investing mainly in Singapore-listed equities, blended-finance instruments, and qualifying unlisted Singapore companies. The first test is at the end of the first full financial year after the award starts.
The first two years
The sequence below applies to an award that starts part-way through a financial year. MAS's circular uses the example of an award starting on 1 August with a 31 December year-end: the team must be complete by that first 31 December, and the first local investment test falls on the following 31 December.
If a condition is missed
MAS may ask for evidence, such as CPF statements, employment passes or an auditor's certification. The fund must also tell MAS about changes in its investment strategy, owners, directors or investment professionals.
Practical steps
- Put each year-end and declaration deadline in the calendar when the award starts.
- Check the investment team against the MAS definition, not job titles.
- Forecast year-end assets each quarter, against both the minimum and the spending bands.
- Plan local investment before the last month of the year.
- Keep payroll, spending and position records as they are created.
- For awards approved before August 2026, check the transitional conditions in your award letter.
What we could not confirm
This guide is based on MAS's circular FDD Cir 05/2026 of 31 July 2026 and MAS's family-office scheme page as updated on 22 September 2026. We did not read the Income Tax Act sections or IRAS guidance directly. Each award letter sets out the conditions for that fund and takes precedence. Awards approved before 1 August 2026 follow transitional conditions that depend on when the fund applied. Singapore's separate licensing framework for family offices, in force from 15 June 2026, has its own annual return, which this guide does not cover. This is education, not legal or tax advice.
