How to Start a Chartered Accountant Practice or CA Firm in India

A Chartered Accountant in practice may provide professional services in areas permitted by the Chartered Accountants Act, 1949, the Chartered Accountants Regulations, 1988, ICAI Council guidelines and the Code of Ethics. Starting a CA practice is therefore different from starting an ordinary accounting business: professional eligibility, a valid Certificate of Practice and ICAI rules governing the form and conduct of practice must be followed.

The original subject also referred to Certified Public Accountants or CPAs. CPA is a professional designation used in jurisdictions outside India and is governed by the licensing law and professional body of the relevant jurisdiction. A foreign CPA qualification by itself does not confer the statutory right to practise as a Chartered Accountant in India. This article therefore focuses primarily on the Indian CA profession.

Legal Framework for Chartered Accountants in India

The profession is regulated principally by the Institute of Chartered Accountants of India (ICAI) under the Chartered Accountants Act, 1949, together with the Chartered Accountants Regulations, 1988, rules, Council guidelines and the ICAI Code of Ethics.

Section 2: Member in Practice

Section 2 of the Chartered Accountants Act, 1949 contains the statutory definitions and explains circumstances in which a member is deemed to be in practice. In broad terms, professional practice includes offering specified accountancy and related professional services for remuneration, whether individually or in partnership with other chartered accountants in practice, subject to the Act and applicable regulations.

Section 6: Certificate of Practice

Section 6 is fundamental to starting practice. It provides that a member of ICAI is not entitled to practise, whether in India or elsewhere, unless the member has obtained a Certificate of Practice from the Council. A person planning to open a CA practice should therefore complete the current ICAI membership and Certificate of Practice requirements before commencing professional practice.

Section 7: Designation of Chartered Accountant

Section 7 deals with the use of the designation "chartered accountant". The use of professional descriptions, firm names, qualifications and designations must comply with the Act, Regulations, Council directions and ethical requirements.

What Work Can a Chartered Accountant Practice Undertake?

A CA practice may work in accounting, assurance, taxation, financial reporting, advisory and other professional areas permitted under the governing professional framework. Certain statutory audits, certifications and attest functions are governed by specific laws and eligibility or independence requirements, so the practitioner must assess the applicable statute before accepting an engagement.

Accounting and bookkeeping advisory
Audit and assurance engagements where legally eligible
Direct and indirect tax services
GST and TDS compliance support
Financial statements and reporting
Management consultancy and other services permitted by ICAI
Internal controls, systems and process advisory
Business, financial and transaction advisory within the permitted professional framework

Forms of CA Practice

A qualified member should not assume that every general business structure is automatically permissible for professional practice. The form of a CA practice must comply with the Chartered Accountants Act, Regulations and ICAI requirements. Common professional structures include individual practice under a proprietorship and eligible firms or LLPs constituted and registered in accordance with ICAI requirements.

Individual or Proprietorship Practice

A qualified ICAI member holding a valid Certificate of Practice may establish an individual practice subject to ICAI requirements. The practitioner should complete the current firm-name and firm-registration formalities applicable through ICAI before using the professional firm name.

A small practice may begin with a modest office or other professional setup suited to its work. Capital requirements vary according to location, staff, software, equipment, subscriptions, professional indemnity arrangements if chosen, and the type of services undertaken. There is no single statutory minimum capital amount for an ordinary individual CA practice.

Partnership Firm and LLP

Two or more eligible professionals may form a partnership or LLP where permitted, but professional composition and firm registration must comply with ICAI rules. The ICAI Council Guidelines include guidance relevant to CA firms, LLP conversion, multidisciplinary partnerships, networking, merger and demerger arrangements.

For an LLP, the Limited Liability Partnership Act, 2008 also applies to the entity. Professional eligibility under the CA regulatory framework remains essential even though the entity is formed under LLP law.

Office, Staff and Facilities

The facilities needed depend on the size and specialization of the practice. Modern professional work is increasingly digital, but client confidentiality, records management and information security should guide the office setup.

Suitable office or professional workspace
Computers, secure internet and reliable backup systems
Licensed accounting, tax, audit and office software as required
Secure document storage and encrypted backup
Multi-factor authentication and controlled access to client information
Printer and scanner where required
Professional reference and research resources
Qualified assistants, articled assistants and administrative staff as permitted and required

Opening a Bank Account for the Practice

The old practice of treating a Service Tax Registration Certificate as a standard account-opening document is obsolete. Service Tax was subsumed into GST. Current bank documentation depends on whether the practice is a proprietorship, partnership or LLP and on the bank's customer due-diligence requirements.

The bank may require PAN, proof of identity and address, constitution or partnership documents, firm registration particulars, authorization for signatories and other documents appropriate to the legal form. Current KYC requirements should be confirmed with the selected bank and the Reserve Bank of India.

GST and Tax Registration

Professional services supplied by a CA practice may be subject to GST. Registration liability should be determined under Sections 22 and 24 of the Central Goods and Services Tax Act, 2017 and applicable notifications, taking into account aggregate turnover, location, nature of supplies and any compulsory-registration provision that applies. Current taxpayer services are available through the GST Portal and official GST law and notifications are available from CBIC GST.

Professional Ethics, Solicitation and Advertising

A CA practice is subject to professional ethics and cannot be marketed in the same way as an unrestricted commercial business. Part I of the First Schedule to the Chartered Accountants Act, 1949 contains provisions concerning professional misconduct by a Chartered Accountant in practice, including restrictions relevant to solicitation and advertising.

ICAI revised its Code of Ethics with the 13th Edition applicable from April 1, 2026. Members and firms should therefore use the current ICAI Council Guidelines and ICAI Ethical Standards Board resources when deciding how a firm may advertise, maintain a website, describe services, use social media or otherwise communicate with prospective clients.

Any website, advertisement, professional communication, firm listing or public statement should comply with the current Code of Ethics and applicable Council guidelines. Older blanket statements that professional advertising is simply "banned" are not sufficiently precise because ICAI permits specified forms of professional communication subject to detailed conditions.

Building a Professional CA Practice

A sustainable practice should be based on professional competence, independence where required, confidentiality, quality management and timely compliance. Before accepting work, the practitioner should confirm that the engagement is permitted, that any statutory eligibility requirements are satisfied, and that conflicts or independence concerns have been addressed.

Define the firm's permitted service areas and technical expertise.
Use engagement letters that clearly state scope and responsibilities.
Maintain client acceptance, KYC and conflict-checking procedures appropriate to the engagement.
Protect confidential and personal information through suitable technology and access controls.
Maintain continuing professional education and monitor changes in tax, company, GST, audit and accounting law.
Follow applicable Standards on Auditing, accounting standards, assurance standards and ICAI pronouncements for relevant engagements.
Maintain proper working papers and retention procedures.

Chartered Accountant and CPA: Important Distinction

"Chartered Accountant" in India is a statutory professional designation governed by the Chartered Accountants Act, 1949 and ICAI. "Certified Public Accountant" generally refers to a professional accountancy designation regulated under the law of another jurisdiction, particularly in the United States. Eligibility, licensing, firm ownership, attest rights and continuing education rules for a CPA practice must therefore be checked with the relevant state board or professional regulator in the country where the person intends to practise.

Important: CA practice is a regulated profession. Before starting, restructuring or marketing a professional firm, verify the current Chartered Accountants Act, Regulations, ICAI Code of Ethics, Council guidelines and applicable statutory requirements. Professional rules can change, and special restrictions may apply to firm names, partnerships, LLPs, networks, advertising, attest work and multidisciplinary arrangements.
