What Is This Legislation About?
The Accountants (Prescribed Standards and Code of Professional Conduct and Ethics) Order 2023 (“the Order”) is a Singapore subsidiary legislative instrument that “prescribes” the standards and ethical code that public accountants and accounting entities must follow when providing public accountancy services. In practical terms, it converts certain professional benchmarks—auditing standards, quality control/quality management standards, and a professional ethics code—into legally relevant requirements under the Accountants Act 2004.
The Order is not a standalone compliance regime. Instead, it operates as a regulatory bridge between (i) the Accountants Act 2004’s framework for regulating public accountancy services and (ii) the detailed technical standards issued by professional bodies. The Public Accountants Oversight Committee (PAOC) uses its statutory power under section 64AA of the Accountants Act 2004 to prescribe what counts as “professional standards,” “quality control standards,” and the “code of professional conduct and ethics” for specified statutory purposes.
Accordingly, the Order matters most to practitioners and regulated entities that provide public accountancy services to “permitted entities” and other entities. It determines which auditing standards apply, which quality control and quality management standards must be met, and which ethics code is legally recognised for compliance purposes.
What Are the Key Provisions?
Section 1 (Citation and commencement) provides the formal name of the instrument and states that it comes into operation on 1 July 2023. This is important for determining the effective date of compliance obligations and for assessing whether conduct occurred under the earlier or later prescribed regime.
Section 2 (Definitions) sets the interpretive anchors for the Order. It defines, by reference to the Accountants Act 2004, the terms “accounting entity,” “professional standards,” and “quality control standards.” This drafting technique is common in Singapore regulatory instruments: the Order relies on the Act’s definitions so that the prescribed standards align with the Act’s regulatory scope.
Section 3 (Prescribed professional standards) is the core provision for auditing standards. It prescribes which auditing standards apply depending on the type of client and the regulatory category of the entity served.
Under Section 3(1)(a), where public accountancy services are provided to a permitted entity, the prescribed professional standards are either:
- the Singapore Standards on Auditing (SSA) issued by the Institute of Singapore Chartered Accountants (ISCA) specified in the First Schedule; or
- the International Standards on Auditing (ISA) issued by the International Federation of Accountants (IFAC) specified in the Second Schedule.
Under Section 3(1)(b), where public accountancy services are provided to any other entity, the prescribed professional standards are the Singapore Standards on Auditing in the First Schedule.
Section 3(2) clarifies key terms used in the professional standards provision. It defines “entity” broadly (including sole proprietorships, corporations, partnerships, other bodies of persons, and trusts) and defines “permitted entity” in a cross-border and listing context. A “permitted entity” includes entities:
- incorporated/formed/registered/established in Singapore and listed on a stock exchange outside Singapore; or
- incorporated/formed/registered/established outside Singapore and whose shares or stock are quoted or listed on a stock exchange operated by Singapore Exchange Limited.
For practitioners, this distinction is crucial: it determines whether the engagement may be performed using ISA (as an alternative to SSA) or must use SSA only. In other words, the Order creates a client-category-based choice (or restriction) on the applicable auditing standards.
Section 4 (Prescribed quality control standards) prescribes the quality control and quality management standards that must be met for the statutory purposes tied to “quality control standards” in the Accountants Act 2004. It does so by reference to standards issued by ISCA specified in the Third Schedule. The prescribed standards are:
- Singapore Standards on Quality Control (specified in Part 1 of the Third Schedule); and
- Singapore Standards on Quality Management (specified in Part 2 of the Third Schedule).
From a compliance perspective, this means that firms and accounting entities subject to the Act’s quality control framework must align their internal systems, policies, and procedures with these ISCA-issued standards. The legal significance is that these standards are not merely “best practice”; they are the prescribed benchmarks for statutory purposes.
Section 5 (Prescribed code of professional conduct and ethics) prescribes the ethics code applicable for the purposes of section 64AA(1)(a) of the Accountants Act 2004. The prescribed code is the Code of Professional Conduct and Ethics applicable to public accountants and accounting entities set out in the Fourth Schedule.
This provision is particularly important for disciplinary and enforcement contexts. Ethics codes typically cover independence, integrity, objectivity, confidentiality, professional competence and due care, and other conduct requirements. By prescribing the code through subsidiary legislation, the PAOC effectively elevates the ethics code into a legally enforceable standard tied to the Act’s regulatory mechanisms.
Schedules (First to Fourth) provide the detailed content. The extract indicates that:
- First Schedule lists the Singapore Standards on Auditing (SSA).
- Second Schedule lists the International Standards on Auditing (ISA).
- Third Schedule lists Singapore Standards on Quality Control and Singapore Standards on Quality Management.
- Fourth Schedule sets out the Code of Professional Conduct and Ethics.
For legal and compliance work, the schedules are where the “real” technical requirements live. Practitioners should ensure they are using the correct version of the standards as incorporated by the schedules (and track amendments over time).
How Is This Legislation Structured?
The Order is structured in a straightforward, practitioner-friendly way:
- Sections 1–2 handle commencement and definitions.
- Section 3 addresses professional standards for auditing engagements, including a client-category-based approach (permitted entities vs other entities) and the SSA/ISA choice.
- Section 4 addresses quality control standards by prescribing ISCA standards on quality control and quality management.
- Section 5 prescribes the code of professional conduct and ethics by reference to the Fourth Schedule.
- Schedules then list the actual standards and the ethics code text.
This structure reflects the regulatory technique of “prescribe by reference”: the legal instrument sets the framework and identifies the applicable standards, while the schedules contain the substantive content.
Who Does This Legislation Apply To?
The Order is made under the Accountants Act 2004 and is designed to apply to those providing public accountancy services to relevant categories of clients and through relevant regulated structures. While the extract does not reproduce the full Accountants Act 2004 definitions, it indicates that the Order’s key terms—“accounting entity,” “professional standards,” and “quality control standards”—are defined by the Act.
In practical terms, the Order affects:
- Public accountants performing audit and related public accountancy services; and
- Accounting entities (which may include firms and other bodies, including trusts) that provide such services and are subject to the Act’s quality control and ethics requirements.
The client category also matters. If the engagement is for a permitted entity, the prescribed professional standards include both SSA and ISA options. If the engagement is for any other entity, SSA applies.
Why Is This Legislation Important?
This Order is important because it makes professional standards and ethics codes legally operative. In the accounting regulatory environment, the difference between “guidance” and “prescribed standards” can be decisive in enforcement, litigation, and regulatory investigations. By prescribing SSA/ISA, quality control/quality management standards, and the ethics code, the PAOC provides a clear benchmark against which conduct and engagement quality can be assessed.
From a practitioner’s standpoint, the most significant compliance implications are:
- Audit standards selection: determining whether SSA-only applies or whether ISA may be used for permitted entities. This affects planning, documentation, reporting, and internal review processes.
- Quality management systems: ensuring that firm-level quality control/quality management policies align with the prescribed ISCA standards in the Third Schedule.
- Ethics compliance: embedding the prescribed Code of Professional Conduct and Ethics into training, independence monitoring, engagement acceptance, and ongoing compliance checks.
Finally, the Order’s amendment history (as reflected in the provided timeline) underscores that practitioners must monitor updates. The extract shows amendments by various subsidiary legislation instruments (e.g., S 741/2023, S 958/2024, S 317/2025). Even where the legal structure remains stable, the incorporated standards in schedules may be updated, affecting what “compliance” means in practice at different times.
