IESBA Tax Planning Standards Now Effective

Momentum builds globally as jurisdictions adopt the standards

Jul 1, 2025 | New York, New York | English

The first global Ethics Standards on Tax Planning, launched by the IESBA in April 2024, become effective today.

The landmark standards are designed to provide a robust ethical framework to guide professional accountants when providing tax planning services or performing tax planning activities, thereby enabling them to make ethical judgments and decisions in this complex area.

Instead of relying solely on a technical or rules-based approach, professional accountants apply a principles-driven framework that offers consistent guidance for tax planning services or activities. This framework may also be followed by other tax practitioners who wish to adhere to a high ethical benchmark.

The objective of the framework is to help ensure that tax planning decisions take into account the public interest, including that they have a credible basis in laws and regulations and that they take into consideration the potential reputational, commercial, and broader economic consequences to which the tax planning arrangement could give rise.

Given the growing public scrutiny of certain tax avoidance practices which can undermine public trust in companies and damage reputations, these standards help accounting firms and tax practitioners by offering a sound ethical foundation for advising on tax planning. In doing so, they contribute to building public and institutional confidence in tax – an area that sits at the heart of the implicit social contract between individual and corporate taxpayers and the societies in which they live or operate.

“Today marks an important milestone for IESBA and the global accounting profession," said Gabriela Figueiredo Dias, IESBA Chair. "The Global Ethics Standards on Tax Planning provide a vital tool to help firms and professionals navigate the complex and often grey areas of tax planning, ensuring the public interest remains at the forefront. I commend all those who are leading the way by adopting or working towards the adoption of these standards”.

The IESBA is pleased to recognize and congratulate the following jurisdictions, which have already adopted the standards: Australia, Hong Kong SAR, Saudi Arabia, Singapore, and South Africa.

“The adoption of IESBA’s new global tax planning standards into the Australian Code constitutes a significant enhancement to the ethical framework governing the behavior of the accounting profession providing tax services in Australia, and upholds the paramount principle of serving the public interest.”

Embracing the IESBA’s Tax Planning Standards strengthens trust in our profession and bolsters the credibility of our members and tax professionals as ethical, trusted advisors.”

Edward Au, President, Hong Kong Institute of Certified Public Accountants (HKICPA)

“As part of SOCPA’s commitment to serve the public interest and ensure harmony with the international professional and ethical standards, we adopted the Tax Planning standards as we found them providing additional clear guidance for professionals to act in accordance with the Ethical Requirements (approved IESBA Code of Ethics) in Saudi when dealing with complex tax issues.”

Dr. Ahmed bin Abdullah Al-Meghames, CEO, Saudi Organization for Chartered and Professional Accountants (SOCPA)

“ISCA is proud to be among the early adopters of IESBA’s Tax Planning and Related Services standards. The standards provide a clear, globally applicable ethical framework for professionals navigating complex tax issues, serving as a practical guide to help them comply with the IESBA’s Code of Ethics. This is a step forward in promoting responsible tax conduct and upholding the reputation of the profession.”

Ms. Fann Kor, CEO, Institute of Singapore Chartered Accountants (ISCA)

“We are proud to be among the first jurisdictions to adopt these standards, affirming our leadership in global ethics and governance. Harmonizing with the IESBA Code underscores our role as a forward-looking jurisdiction that supports transparency and global accountability.”

Imre Nagy, CEO, Independent Regulatory Board for Auditors (IRBA)

Other jurisdictions, such as India and Japan, are also making significant progress toward adopting, or actively considering adopting, the standards, which helps build momentum toward further alignment around a global ethical foundation and baseline for tax planning.
