Statutory Audit for Private Limited Companies - Section 139 and CARO 2020

Pvt Ltd-specific audit rules apply different thresholds than the general framework. A small Pvt Ltd under Section 2(85) (paid-up up to Rs 10 crore and turnover up to Rs 100 crore post G.S.R. 880(E)) is exempt from CARO 2020 but still needs a statutory audit. A Pvt Ltd with turnover under Rs 50 crore is exempt from Section 143(3)(i) IFC reporting but the audit itself remains mandatory. A Pvt Ltd with paid-up share capital under Rs 50 crore is exempt from Section 139(2) auditor rotation. Patron applies the right combination of CARO 2020, IFC and rotation rules for your size and stage.

Patron Accounting LLP conducts ICAI Standards on Auditing compliant statutory audits for private limited companies under Section 139 of the Companies Act 2013. Mandatory regardless of turnover or profit, with CARO 2020 21-clause reporting where applicable, Section 143(3)(i) IFC reporting for Pvt Ltds above the Rs 50 crore turnover or Rs 25 crore borrowings threshold, and ADT-1 plus AOC-4 filing support. Fixed-fee from Rs 35,000 with senior CA partner review, UDIN registration and a workpaper retention archive that satisfies ICAI quality review and ROC adjudication scrutiny.

Statutory audit applies to every private limited company in India under Section 139 of the Companies Act 2013. The audit itself is universal; what changes with company size is the reporting scope - CARO 2020 21-clause coverage, Section 143(3)(i) IFC reporting, and Section 139(2) auditor rotation each have their own applicability thresholds.

Who needs Pvt Ltd statutory audit:

• Newly incorporated private limited companies - first auditor required within 30 days under Section 139(6); ADT-1 within 15 days of board appointment (mandatory from 14 July 2025 MCA amendment).
• Active Pvt Ltds in years 2+ - subsequent auditor 5-year term under Section 139(1); annual audit cycle aligned to FY end and AGM.
• Pvt Ltds qualifying as small companies under Section 2(85) - audit mandatory; CARO 2020 not applicable; MGT-7A used instead of MGT-7.
• Pvt Ltds with turnover above Rs 50 crore - full statutory audit plus Section 143(3)(i) IFC reporting plus CARO 2020 21-clause coverage.
• Pvt Ltds with paid-up capital above Rs 50 crore - all of the above plus Section 139(2) auditor rotation.
• Pvt Ltds with foreign holding or PE investors - full audit with additional consolidation, transfer pricing and FEMA reporting integration.

Pvt Ltd statutory audit is the most universal and the most variable corporate compliance engagement in India. Every Pvt Ltd needs one, but the scope changes sharply with size - CARO 2020, Section 143(3)(i) IFC and Section 139(2) rotation each kick in at different thresholds. A correctly scoped audit at the right tier, with documented workpapers and partner review, is a fundraising and M&A asset. A wrongly scoped audit creates diligence flags and rework.

Patron Accounting LLP - a CA and CS practice with 15+ years of regulatory experience and offices in Pune, Mumbai, Delhi and Gurugram - delivers Pvt Ltd statutory audit as a managed engagement starting at Rs 35,000 (Tier 1 small Pvt Ltd). The engagement includes correct CARO 2020 four-criteria mapping, Section 143(3)(i) IFC exemption test under G.S.R. 583(E), Section 139(2) rotation eligibility check, SA 700 reporting with UDIN, ADT-1 and AOC-4 filing, and senior CA partner review on every report.

Cross-sell to /appointment-of-auditor, /private-limited-company-compliance, /tax-audit, /gst-audit and /roc-notice delivers a single point of accountability across the full Pvt Ltd compliance perimeter - one CA pod, one engagement letter, one UDIN registry.
