EP 100 (revised on 20 March 2025) – Expected to be Effective 1 July 2025

EP 100 establishes ethical requirements for members of the Institute of Singapore Chartered Accountants (ISCA) and is modelled after the International Code of Ethics for Professional Accountants issued by the International Ethics Standards Board for Accountants (IESBA).

ISCA has issued EP 100 (revised on 20 March 2025) to adopt the IESBA’s final pronouncement, Revisions to the Code Addressing Tax Planning and Related Services (Tax Planning FP).

EP 100 (revised on 20 March 2025) is expected to be effective 1 July 2025.

The Tax Planning FP introduces two new sections to EP 100 to address tax planning (TP) and related services:

  • Section 280 to guide judgements and decisions when professional accountants in business (PAIBs) perform TP activities for employing organisations.
  • Section 380 to guide judgements and decisions when professional accountants in public practice (PAPPs) provide TP services to clients.

Sections 280 and 380 establish a comprehensive ethical framework to guide PAIBs and PAPPs when performing TP activities or providing TP services. Among other matters, the proposed ethical framework:

  • Establishes the principle that PAIBs and PAPPs recommend or otherwise advise on a TP arrangement only if they have determined that there is a credible basis in laws and regulations for it.
  • Requires consideration of the reputational, commercial and wider economic consequences that could arise from the way stakeholders might view the TP arrangement before determining whether to proceed with the recommendation or advice.
  • Provides guidance to assist PAIBs and PAPPs in navigating situations of uncertainty when performing TP activities or providing TP services.
