Two limits apply: the Companies Act and ICAI:
• Sec 141(3)(g): a CA can be auditor of up to 20 companies (excluding OPCs, dormant companies, small companies, and private companies with paid-up share capital below Rs 100 crore, per MCA Notification of 13 June 2017). So small companies and OPCs don't count towards the 20.
• ICAI guideline (Council Guidelines, 2008 and later): a member in practice shouldn't hold more than 30 audit assignments of companies in a FY (for a firm, 30 per partner). Private companies, OPCs and small companies are counted (with certain exclusions for audit of branches). Check the latest ICAI guidelines for exclusions.
• Separately, tax audits are capped at 60 per member (ICAI guideline). Some audits under other laws are excluded.
• So the practical cap for small companies/OPCs is ICAI's 30, not the Companies Act's 20.
