What is a Chartered Accountant?
A Chartered Accountant (CA) is a qualified finance and accounting professional who is a member of the Institute of Chartered Accountants of India (ICAI), regulated under the Chartered Accountants Act, 1949. A CA holding a Certificate of Practice can audit accounts, file and represent on taxes, and certify financial documents.
The CA qualification is statutory, so the title and its exclusive functions are protected by law, not merely a job description.
Key terms explained
- ICAI: The Institute of Chartered Accountants of India, the statutory body that regulates CAs.
- Certificate of Practice (COP): The licence a CA needs to practise and sign audit reports.
- Statutory audit: A legally required audit of a company's financial statements.
- UDIN: Unique Document Identification Number a CA assigns to certified documents.
What a CA actually does, day to day
A CA's work spans five broad areas: audit and assurance, direct and indirect taxation, accounting and bookkeeping, statutory certification, and financial advisory.
Crucially, only a CA in practice can conduct a statutory audit and sign the audit report of a company under the Companies Act, 2013, and a tax audit under Section 44AB of the Income-tax Act, 1961 for FY 2025-26 (Section 63 of the Income-tax Act, 2025 from Tax Year 2026-27).
Trust check: any document certified by a CA carries a UDIN that you can verify free on the ICAI portal, which confirms a genuine CA signed it.
What a Chartered Accountant does
| Area | Typical work | CA-exclusive? |
|---|---|---|
| Audit & assurance | Statutory, tax and internal audits | Yes (statutory/tax audit) |
| Taxation | ITR, GST, TDS, planning, representation | Mostly shared |
| Accounting | Bookkeeping, financial statements | Shared |
| Certification | Net worth, turnover, visa certificates | Yes (with UDIN) |
| Advisory | Business, finance and compliance advice | Shared |
Common mistakes to avoid
- Assuming any accountant can audit — hiring a non-CA to sign an audit report; the audit is invalid and can be rejected by the ROC or tax department.
- Not verifying the UDIN — accepting a certificate without checking; you may rely on a forged certificate.
- Confusing a CA with a tax consultant — treating every 'tax consultant' as a CA when they may not be allowed to certify or audit.
Why the CA monopoly on audit exists
Signing an audit report or certifying documents as a CA without being an ICAI member in practice is a punishable offence under the Chartered Accountants Act, 1949.
A company's statutory audit under the Companies Act, 2013 must be conducted by a CA in practice; a report signed by anyone else is not a valid statutory audit.
A statutory audit under the Companies Act, 2013 and a tax audit under Section 44AB are distinct, but both can only be signed by a CA in practice. The UDIN requirement links every CA-certified document to the ICAI's central register, so certification and verification are tied together.
