Section 13O vs 13U Singapore — Family Office Tax Schemes Compared

The two Singapore Income Tax Act sections (formerly 13R and 13X) that grant a tax exemption on specified investment income for resident family-office structures. 13O is the smaller-AUM scheme. 13U is for larger or growing family offices.

Verified 2026-06-07 against MAS published guidance + IRAS commentary. Always confirm current thresholds with qualified Singapore counsel before applying.

TL;DR — short answer
Section 13O (formerly 13R) covers smaller SG-resident family offices — minimum S$20M AUM, 2 investment professionals, S$200k annual SG business spend. Section 13U (formerly 13X) covers larger family offices — minimum S$50M AUM, 3 professionals (one a non-family member), S$500k–1M annual SG business spend. Both require ≥10% AUM (or S$10M, whichever lower) in local SG investments. Migrate from 13O to 13U as assets cross S$50M.

Decision tree

Start: What is your investable AUM at application?

Under S$20M

Neither scheme yet. Build to S$20M+ before applying, or consider a non-exempt structure with normal Singapore taxation. See family-office Singapore for alternatives.

S$20M – S$50M

Section 13O. Lower compliance burden, 2 investment professionals, S$200k business spend. If you expect to cross S$50M in the next 2-3 years, factor in the future 13U migration.

S$50M – S$150M

Section 13U preferred. 3 investment professionals (1 non-family), broader investment-strategy mandates. The non-family-member rule is the main constraint to plan for at this band.

S$150M+

Section 13U. Headcount and business-spend minimums easily cleared. At this scale also consider whether a VCC (Variable Capital Company) sub-fund structure or co-mingled MFO arrangement is operationally cleaner.

Migration: 13O → 13U

Many SG single-family offices begin under 13O when AUM is below S$50M and migrate to 13U once AUM and operating scale clear the larger thresholds. Migration is not automatic — it requires:

  • A new MAS application for the 13U status
  • Meeting all 13U headcount, business-spend, and local-investment requirements at application date
  • Updated investment policy + organisation chart + employment evidence
  • Typical timeline: 3–6 months end-to-end

Singapore advisors typically recommend planning the migration ~12 months ahead of expected AUM crossing.

Common mistakes

Underestimating ongoing business spend

The S$200k (13O) / S$500k+ (13U) minimum is a floor, not a planning target. Real operating cost for a credible Singapore FO runs S$400k–1.5M for 13O and S$1M+ for 13U.

Treating "investment professional" as flexible

MAS scrutinises actual investment-decision-making. Administrative or ops headcount does not count. The professional must be substantively involved in investment decisions.

Skipping the local-investment requirement

10% AUM or S$10M (whichever lower) must be deployed into local SG investments — this is not optional and is reviewed annually.

Confusing 13O with 13D

13D is for non-resident funds (offshore investors). 13O and 13U are for Singapore-resident family-office structures. The structures are not interchangeable — see 13D vs 13O/13U.
