The governing constraint
What ICAI permits on a firm website
A website for chartered accountants is governed before it is designed. Practising CAs are bound by ICAI's Code of Ethics and Council guidelines, which restrict advertising and solicitation of professional work. A firm website is permitted, but it has historically been treated on a pull basis: a person seeking you finds it, rather than it being pushed at people who did not ask. That single principle explains most of the specific restrictions that follow.
What a website for chartered accountants may broadly carry, and what we build with: firm and member names, membership and firm registration numbers, office addresses and contact details, partner and staff details with qualifications, the services offered, and the areas in which the practice has experience. Factual, verifiable, informational.
Broadly restricted, and what we leave out: claims of superiority or comparison with other firms, client names and logos, testimonials, and anything resembling a solicitation such as unsolicited bulk announcements. The treatment of fee display and photographs has been narrower than most professionals expect and has changed across revisions of the guidance.
One honest caveat, because it matters more than a confident answer would. ICAI's ethical standards have been revised more than once, including a substantially restructured Code of Ethics, and the detail on specific items has shifted between versions. We build to the conservative reading and flag anything borderline in writing rather than deciding it for you — and for genuinely marginal items, the right step is a note to the Ethical Standards Board before publishing, not a designer's judgement.
