IESBA Program and Senior Director Ken Siong discusses a recent shift in how the IESBA develops its international ethics and independence standards: the Staff Driven Model. Learn how the IESBA is moving from board-led task forces to empowered staff-led project teams, why this change aligns with global regulatory reforms, and how the model is already being piloted with promising results.

The International Ethics Standards Board for Accountants (IESBA) has released Firm Culture and Governance: Summary of Feedback from Global Roundtables, a publication that captures stakeholder perspectives from six global roundtables held earlier this year as part of the Board’s Firm Culture and Governance (FCG) project.

Held in New York, Melbourne, Brussels, and Kuala Lumpur, with virtual sessions for Africa and Latin America, the roundtables brought together 168 participants from across the global regulatory, investor, standard setting, accounting firm, professional accountancy and academic communities. Discussions centered on eight core elements of an ethical firm culture: ethical leadership, oversight and governance, provision of independent input, accountability, incentives and rewards, open discussion and challenge, continuous education and training, and transparency about ethical performance.

These roundtables formed part of the IESBA’s ongoing efforts to ensure its decision-making is informed by a balanced and broad-based representation of all relevant stakeholders, in line with its mandate to serve the public interest by setting global ethics, including independence, standards for the accounting profession. The publication of this report reflects the IESBA’s strong commitment to transparency and responsiveness to stakeholder feedback – both of which are essential to fostering trust among all parties involved in the development of the highest ethics standards for the profession.

The insights gathered through these discussions have directly contributed to the IESBA’s recent decision to remain firmly committed to taking decisive steps to address the cultural and governance dimensions within accounting firms, recognizing their critical impact on ethical behavior. These insights will also shape the IESBA’s future work, referenced in a recent IESBA communication on the topic, including:

• the development of a series of IESBA Viewpoints addressing eight key elements to a Firm Culture and Governance Framework, such as ethical leadership, accountability, and incentives and rewards;
• the preparation of a comprehensive plan, to be launched in 2026, for practical guidance and other initiatives to help firms foster an ethical culture and embed values that sustain long-term public trust in them; and
• the decision to consider, by mid-2026, the appropriate approach to developing a Firm Culture and Governance Framework, aimed at guiding firms in strengthening their ethical culture and related governance practices.

About IESBA

The International Ethics Standards Board for Accountants (IESBA) is an independent global standard-setting board. The IESBA’s mission is to serve the public interest by setting high-quality, international ethics (including independence) standards as a cornerstone to ethical behavior in business and organizations, and to public trust in financial and non-financial information that is fundamental to the proper functioning and sustainability of organizations, financial markets and economies worldwide.

Along with the International Auditing and Assurance Standards Board (IAASB), the IESBA is part of the International Foundation for Ethics and Audit (IFEA). The Public Interest Oversight Board (PIOB) oversees IESBA and IAASB activities and the public interest responsiveness of the standards.

The Firm Culture and Governance: Summary of Feedback from Global Roundtables publication captures stakeholder perspectives from six global roundtables held in 2025 as part of the Board’s Firm Culture and Governance (FCG) project. 

• The IESBA and IAASB have established technical expert groups to support effective global implementation of the two boards’ sustainability standards.
• Group members bring deep expertise and hands-on experience with the application of the IESSA and ISSA 5000 standards.
• The groups will provide timely, practice-informed feedback and help develop implementation resources that the IESBA and IAASB might commission to support consistent global application.

The International Ethics Standards Board for Accountants (IESBA) and the International Auditing and Assurance Standards Board (IAASB) today announced the recent formation of two expert implementation groups that will play important roles in supporting the effective implementation and application of the Boards’ recently released global sustainability standards:

• The IESBA’s IESSA Implementation Monitoring Advisory Group (IIMAG) will support the implementation of the International Ethics Standards for Sustainability Assurance (including International Independence Standards) (IESSA) and revisions to the IESBA code for sustainability reporting.
• The IAASB’s ISSA 5000 Technical Implementation Contact Group (TICG) will support implementation of the International Standard on Sustainability Assurance (ISSA 5000).

Each group comprises a diverse and globally representative set of professionals with a high level of familiarity with the standards and direct involvement in implementation-related activities. The IIMAG and TICG will provide regular feedback to the Boards to ensure that emerging issues relating to the implementation of the standards are identified and addressed timely, and that implementation support resources remain relevant and practical.

The work of these groups will support and contribute to IESBA and IAASB efforts to support stakeholders’ adoption and implementation of IESSA and ISSA 5000, thereby helping build trust in sustainability information and advancing high-quality assurance practices worldwide.

The International Ethics Standards Board for Accountants (IESBA) welcomes the announcement by Australia's Accounting Professional & Ethical Standards Board (APESB) of the adoption of the IESBA’s Global Ethics Sustainability Standards. With this move, Australia becomes the first jurisdiction to formally embed ethics and independence standards for sustainability reporting and assurance into its national framework. 

Gabriela Figueiredo Dias, IESBA Chair, said:
“Australia’s leadership has sent a powerful signal: ethics and independence must be at the heart of how sustainability information is developed, assured, and trusted. This is more than a milestone, it’s the start of a global movement. As more jurisdictions follow, we’re helping to lay the ethical foundation around the world for a sustainability reporting system that serves the public interest, builds confidence, and drives meaningful change.”

Released in January 2025, the IESBA’s sustainability-related ethics and independence standards include the International Ethics Standards for Sustainability Assurance (IESSA), along with new provisions on sustainability reporting and the use of external experts. Together, they establish globally consistent expectations for ethical conduct and independence in sustainability reporting and assurance.

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.”

Nancy Milne OAM, Chair, Accounting Professional & Ethical Standards Board (APESB)

“At HKICPA, we uphold the public interest and professional integrity and are committed to proactively aligning with international benchmarks. 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.

Implementation Support Resources

The IESBA encourages all professional accountants to familiarize themselves with the standards in order to uphold the profession’s commitment to ethical tax practices. Implementation support resources, including IESBA Staff Questions & Answers, can be accessed on the IESBA website.
