Based on ICAI's official press release from December 12, 2025. This post will be updated once the final published Code document is available.

The 13th Edition of ICAI's Code of Ethics came into effect on April 1, 2026. The revisions were approved at ICAI's 447th Council meeting and represent the most significant update to the Code in recent years. If you are a CA or CA firm wondering what actually changed, here is a plain-English breakdown.

1. Advertising and website guidelines: more flexibility, not a free-for-all

This is the part generating the most noise, and the most misunderstanding.

The Council approved amendments to the Advertisement and Website Guidelines. The stated goal is to give CA firms, especially mid-sized and emerging practices, more tools to enhance their visibility and compete at a global level.

What that means in practice:

The scope of the 'write-up' in advertisements has been expanded, giving members greater creative flexibility in how they describe and present their professional services. Think of it as widening the canvas, not removing the frame.

On the website side, the significant change is around push technology. Members and firms can now use push mode for services that are not exclusive to the CA profession, such as consultancy and accounting advisory. Previously, push technology was more broadly restricted. The carve-out is specifically for non-exclusive services, not for core audit or assurance work.

Network firms registered with ICAI can now also develop and maintain their own websites, which previously was not permitted. This is a meaningful change for networks that want a digital presence independent of individual member profiles.

What has not changed: CAs still cannot use comparative advertising, client testimonials, star ratings, or anything that positions one CA as better than another. The prohibition on soliciting clients directly remains in place. The spirit of the Code, professional reputation built on merit rather than marketing spend, has not shifted.

2. Convergence with IESBA 2024 Code: stricter independence rules

ICAI has now converged with the 2024 edition of the International Ethics Standards Board for Accountants Code, aligning India's ethical standards with the global benchmark.

The practical implications for audit firms are significant:

Non-assurance services for audit clients are further restricted. Specifically, an audit firm cannot accept the audit of a Public Interest Entity if it has previously provided a non-assurance service that could create a self-review threat on the financial statements. This is an express prohibition, not just a consideration to be managed.

The NOCLAR provisions, which govern how auditors respond to non-compliance with laws and regulations, have been extended. They now apply to all listed entities and their material subsidiaries, not just the narrower set covered previously.

For most practicing CAs, this primarily affects those working with listed companies or PIEs. But the direction of travel is clear: independence requirements are tightening, not loosening.

3. New ethical standards for sustainability assurance

For the first time, the Code of Ethics includes specific ethical standards for sustainability assurance engagements. These are based on the International Ethics Standards for Sustainability Assurance issued by IESBA.

This is forward-looking. As ESG reporting requirements grow in India and globally, CAs who take on sustainability assurance work now have a clear ethical framework to operate within. If you are thinking about building a sustainability practice, this is the Code catching up to where the market is heading.

4. Expanded list of management consultancy services

The list of Management Consultancy and Other Services that CAs are permitted to provide has been expanded to include a wider range of contemporary services. The additions include social impact assessment, artificial intelligence-related services, and forensic accounting.

This reflects where client demand is going. CAs who want to build practices in these areas now have explicit Code-level recognition for doing so.

5. Digital-only audit fees

In line with the Government of India's push toward a digital economy, the revised Code recommends that audit fees be accepted only through digital modes or banking channels. Cash payments for audit work are effectively being phased out.

6. Global Networking Guidelines: a new era for Indian CA firms

Separate from the Code amendments but announced alongside them, the ICAI (Global Networking) Guidelines, 2025 have been approved. These allow Indian CA firms, domestic networks, and ICAI-registered consultancy companies to form structured affiliations with international firms and networks.

The stated goal is a level playing field for small and mid-sized Indian firms who previously had no structured pathway to global partnerships. For larger firms this opens formal collaboration frameworks. For smaller firms it opens access to shared knowledge, technology, and global brand association.

The bottom line

The 13th Edition is not a liberalisation in the way some headlines are suggesting. It is a modernisation. The core principles around independence, professional conduct, and the prohibition on comparative advertising remain firmly in place.

What has changed is the framework's ability to accommodate how professional services work in 2026: digital visibility, global networks, sustainability assurance, and AI-adjacent services are now explicitly addressed rather than operating in a grey zone.

For CAs building a practice today, the most practically significant changes are the expanded write-up flexibility in advertising, the push technology allowance for non-exclusive services, and the new website permissions for network firms.

Frequently asked questions

Q: Can CAs now advertise their services freely under the 13th Edition?
A: No. Advertising flexibility has been expanded, particularly around how services are described and the use of push technology for non-exclusive services like consultancy. But CAs still cannot use comparative claims, client testimonials, or star ratings.

Q: What is the difference between push and pull technology under the revised guidelines?
A: Push means a CA or firm's content is served to potential clients, for example through promoted content or targeted digital marketing. Pull means a client finds a CA through their own search or by arriving at a platform for their own purposes. The revised Code permits push for non-exclusive services. Pull was already permitted.

Q: Are there now stricter rules for auditors of listed companies?
A: Yes. The convergence with IESBA 2024 tightens independence requirements, particularly around non-assurance services for Public Interest Entities and the handling of NOCLAR situations, which now apply to all listed entities and their material subsidiaries.

Q: What services can CAs now offer that were not previously recognised in the Code?
A: The expanded MCS list includes social impact assessment, AI-related services, and forensic accounting, among other contemporary professional domains.

Q: When did the 13th Edition come into effect?
A: April 1, 2026, as approved at ICAI's 447th Council meeting in December 2025.
