The Monetary Authority of Singapore (MAS) has refined the qualifying conditions and compliance frameworks under Section 13O (Singapore Resident Fund) and Section 13U (Enhanced Tier Fund) of the Income Tax Act. The adjustments—building on recent policy cycles—signal a clear pivot from volume-based family office attraction toward deeper institutional substance, local economic integration, and enhanced capital deployment.
For principals, family office CEOs, and private wealth advisers, navigating these updated tax exemption parameters requires recalibrating talent acquisition strategies, annual spending commitments, and local capital allocation mandates.

Key Policy Shifts at a Glance

The updated framework establishes firmer operational floors for Single Family Offices (SFOs) while expanding qualifying asset classes to encourage local market participation.

  • S13O Minimum AUM Floor: The minimum fund threshold remains firmly anchored at S$20 million in Designated Investments at application and throughout the tax exemption period, eliminating legacy grace period buffers.
  • S13U Minimum AUM Floor: Set at S$50 million in Designated Investments at point of application.
  • Non-Family Hiring Mandate: Both S13O and S13U schemes enforce the requirement to hire at least one non-family investment professional (IP), driving institutionalization across local operations.
  • Mandatory Capital Deployment (CDR): SFOs under both schemes must deploy at least 10% of AUM or S$10 million (whichever is lower) into qualifying local asset classes.

Strategic Implications for Family Office Principals

1. Professionalizing the Investment Team

The mandate requiring at least one non-family investment professional forces SFOs to move beyond pure family management. Qualifying IPs must be Singapore tax residents with relevant industry track records, earning a minimum base salary threshold. Principals should structure competitive compensation packages—including co-investment rights—to attract and retain experienced local talent.

2. Optimizing the Capital Deployment Requirement (CDR)

To satisfy the CDR, SFOs are incentivized to utilize MAS-recognized deployment multipliers:

  • 1.0x Weighting: Standard allocations to SGX-listed equities, qualifying domestic debt securities, and unlisted Singapore operating entities.
  • Multiplier Adjustments: Investments into local climate-related projects, green bonds, and blended finance structures backed by Singapore financial institutions receive enhanced weighting (1.5x to 2.0x) toward meeting the minimum CDR threshold.

3. Rigorous Due Diligence & Screening Protocols

Regulatory adjustments have elevated background checks and screening standards. SFO applicants must submit independent background screening reports issued by MAS-authorized risk agencies alongside annual compliance declarations, making robust AML/KYC documentation essential prior to formal submission.

Actionable Next Steps

For existing awardees and prospective applicants, maintaining tax exemption status requires active annual tracking. SFO boards should conduct bi-annual audits of local business spending (LBS), verify investment professional residency compliance, and review CDR capital allocations prior to annual MAS filings.
