Classification of Subordinated Perpetual Securities as “Debt Securities”

by | Nov 5, 2025 | Accounting, Income Tax, Tech News

The Inland Revenue Authority of Singapore (IRAS) has issued Advance Ruling (Income Tax) Summary No. 21/2025, addressing the tax classification of subordinated perpetual securities issued by a Singapore-incorporated company. The ruling examines whether such instruments qualify as “debt securities” for purposes of Section 43H(4) of the Income Tax Act 1947 (ITA) and Regulation 2 of the Income Tax (Qualifying Debt Securities) Regulations.

Key Features of the Instrument Considered

The securities in question exhibit the following characteristics:

  • Periodic Distributions: Holders are entitled to semi-annual distributions, payable in arrears.
  • Perpetual Tenure: The instruments have no fixed maturity date, though the issuer retains redemption rights under specified conditions.
  • Subordination Terms: In a winding-up scenario, claims of securityholders rank:
    • Below senior creditors,
    • Pari passu with other subordinated obligations not expressly junior, and
    • Ahead of ordinary shareholders.
  • Debenture Holder Status: Securityholders are recorded in the issuer’s Register of Debenture Holders.

Based on these characteristics, the IRAS considered whether the securities fall within the statutory definition of debt securities for tax incentive and withholding tax purposes.

Tax and Accounting Implications

1. Potential Qualification as “Debt Securities”

The ruling suggests that subordinated perpetual securities may still be treated as debt for Singapore tax purposes despite having equity-like features, including perpetual duration and deeply subordinated ranking. The decisive factors appear to include:

  • Existence of contractual payment obligations (even if discretionary in practice),
  • Holder status as debenture holders,
  • Treatment aligned with borrowing arrangements where noteholders remain creditors in liquidation.

Practical Impact

  • Issuers may access Qualifying Debt Securities (QDS) schemes, potentially benefiting from reduced or exempt withholding tax on distributions.
  • Proper structuring and documentation are essential to demonstrate debt-like intent despite hybrid characteristics.

2. Financial Reporting Issues

While the ruling relates to tax classification, entities must separately evaluate accounting classification under SFRS(I) 1-32 Financial Instruments: Presentation.

Likely Accounting Outcome

Given the perpetual tenure, optional redemption, and potential distribution deferral, these instruments commonly meet the definition of equity instruments for financial reporting—unless the issuer is obliged to deliver cash.

Practical Issues for Accountants

  • Mismatch risk:
    A security may be treated as equity for accounting but debt for tax. This may give rise to:
    • Deferred tax considerations,
    • Complex earnings-per-share effects,
    • Disclosure requirements under SFRS(I) 7.
  • Distribution deductibility:
    Even if distributions resemble “interest,” deductibility depends on tax classification. The ruling may support deductibility in certain cases, but professional evaluation is advised.
  • Capital management disclosures:
    Hybrid capital instruments require transparent disclosure of:
    • Terms affecting cash flows,
    • Subordination,
    • Redemption options.

3. Practical Considerations for Issuers

  • Document the nature of obligations explicitly, especially payment terms and ranking.
  • Review QDS eligibility criteria, including credit ratings, listing requirements, and specified issuance conditions.
  • Coordinate legal, tax, and accounting advice early in structuring to avoid unintended reclassification.
  • Monitor ongoing compliance, as any amendments to terms may affect tax treatment.

The advance ruling reinforces that subordinated perpetual securities can qualify as “debt securities” for Singapore tax purposes even when exhibiting hybrid or quasi-equity characteristics. However, accounting classification may diverge, creating practical implications for financial reporting, tax planning, and investor communication.

Professionals should carefully evaluate structural features, documentation, and the interplay between tax and accounting frameworks when issuing or advising on such instruments.
