Section 141(3)(g)’s 20-company ceiling is a statutory audit limit under the Companies Act — separate from ICAI’s 60-tax-audit-per-CA ceiling under Section 44AB of the Income-tax Act. A partner can be well within one cap and close to breaching the other; they don’t share a pool and aren’t computed the same way.
Section 141(3)(g) of the Companies Act 2013 disqualifies a person (or a partner of a firm) from being appointed or reappointed as auditor if, at the date of appointment, they already hold appointment as auditor of 20 or more companies. The ceiling is strictly PER PARTNER — a firm's total capacity is simply partners × 20, with no pooling: one partner cannot "lend" unused capacity to another.
The Explanation to Sec 141(3)(g) narrows what actually counts toward the 20: the number is "reckoned exclusive of one person companies, dormant companies, small companies and private companies having paid-up share capital of less than one hundred crore rupees." In practice, that means only two categories count — public companies of any size, and private companies with paid-up share capital of ₹100 crore or more. Everything else — OPCs, dormant companies, Sec 2(85) small companies, and private companies below the ₹100 Cr paid-up threshold — is excluded from the count entirely, however many of them a partner signs.
This is a materially different ceiling from ICAI's 60-tax-audit-per-CA cap under Section 44AB of the Income-tax Act: different statute, different counted population, different aggregation rules (the tax-audit cap aggregates a CA across every firm they are a partner in; the Sec 141(3)(g) ceiling is tested per firm, per partner, for statutory company audits specifically).
Partner A audits 9 public companies, 6 private companies with paid-up capital of ₹150 Cr each, plus 15 private companies each below ₹100 Cr paid-up and 4 small companies.
