Comprehensive Due Diligence Checklist for Corporate Merger and Acquisition in India

Corporate and Secretarial Due Diligence under the Companies Act, 2013

The corporate secretarial review forms the bedrock of any M&A due diligence exercise. It involves verifying the foundational documents of the target company, including the Memorandum of Association (MoA) and Articles of Association (AoA), to identify any restrictive clauses, transfer of shares limitations, or pre-emptive rights that could impede the transaction.

Statutory registers maintained under the Companies Act, 2013—such as the register of members, register of directors, and register of charges—must be meticulously audited. Particular attention must be paid to unregistered charges or unsatisfied mortgages that could crystalize as unexpected secured debt post-acquisition. Furthermore, a review of board minutes and general meeting resolutions for the past three to five years ensures that past corporate actions were duly authorized and compliant.

Special statutory compliances, such as the applicability of Cost Accounting Records and Cost Audit under Section 148 of the Companies Act, 2013, must be verified, especially for manufacturing, mining, or regulated sectors. Any past default in filing annual returns (Form MGT-7) or financial statements (Form AOC-4) with the Registrar of Companies (RoC) must be flagged and factored into the transaction indemnity clauses.

Financial and Accounting Due Diligence: Audited Statements and Cost Records

Financial due diligence goes beyond standard statutory audits to analyze the quality of earnings, sustainable cash flows, working capital cycles, and hidden liabilities of the target entity. Expert Cost Management Accountants (CMAs) deploy analytical tools to assess cost structures, overhead allocations, and inventory valuations.

A deep-dive review of related-party transactions under Section 188 of the Companies Act, 2013 is critical. The finance team must verify whether these transactions were conducted at arm's length and properly approved by the audit committee and board. Undisclosed related-party transactions can distort profitability and trigger severe tax adjustments.

Evaluation of contingent liabilities—such as disputed statutory dues, pending arbitration, guarantees given to third parties, and product warranties—is essential. The acquirer must quantify these risks to negotiate appropriate escrow mechanisms, purchase price adjustments, or indemnity caps in the definitive transaction agreements.

Direct and Indirect Tax Due Diligence: Income Tax and GST Compliance

Tax liabilities represent some of the most substantial post-acquisition risks. Under the Income Tax Act, 1961, due diligence must encompass open tax assessments, pending appeals before the Commissioner of Income Tax (Appeals) or ITAT, and the status of transfer pricing documentation for international and domestic related-party transactions.

For tax-neutral mergers, evaluating compliance with Section 2(19AA) of the Income Tax Act is mandatory to ensure the amalgamation qualifies as a 'demerger' or merger without triggering capital gains tax. Additionally, the availability and carry-forward of accumulated business losses and unabsorbed depreciation under Section 72A require careful validation by tax experts.

On the indirect tax front, the Central Goods and Services Tax (CGST) Act, 2017 requires scrutiny of transitional provisions. A critical step involves the transfer of unutilized Input Tax Credit (ITC) via Form GST ITC-02, which must be executed seamlessly. The due diligence team must review historical GST returns (GSTR-3B and GSTR-1), reconciliation with books of accounts, and historical audits or anti-evasion investigations by indirect tax authorities.

Regulatory, Antitrust, and Sectoral Approvals

Major corporate transactions in India often trigger mandatory merger control filings with the Competition Commission of India (CCI) under Section 5 and Section 6 of the Competition Act, 2002. Transactions breaching prescribed asset and turnover thresholds—or newly introduced Deal Value Thresholds—cannot be consummated without prior CCI clearance.

For listed entities or transactions involving regulated sectors such as banking, insurance, telecommunications, or defense, approvals from sector-specific regulators (e.g., SEBI, RBI, IRDAI) are indispensable prerequisites. Non-compliance with sectoral foreign investment caps under the Foreign Exchange Management Act (FEMA) regulations can render transactions void ab initio.

All schemes of arrangement, merger, or amalgamation must ultimately navigate the National Company Law Tribunal (NCLT) approval process under Sections 230-232 of the Companies Act, 2013, read with Rule 25 of the Companies (Compromises, Arrangements and Amalgamations) Rules, 2016. Due diligence must confirm that shareholder and creditor meetings were conducted with requisite quorums and majorities.

Labor, Employment, and Intellectual Property (IP) Audits

Human capital is frequently the primary asset in M&A deals, yet labor non-compliance remains a major pitfall. Due diligence must verify adherence to central and state labor codes, including the Provident Fund (EPF), Employees' State Insurance (ESI), Gratuity, and Bonus acts. Unfunded gratuity liabilities or systemic misclassification of contractor workers as independent contractors pose severe financial risks.

Intellectual Property (IP) due diligence involves auditing trademarks, patents, copyrights, and domain names owned or used by the target entity. The review must confirm clear title ownership, registration status, absence of third-party infringement claims, and the validity of critical technology licenses or software agreements.

Material commercial contracts—such as customer agreements, vendor contracts, lease deeds, and loan covenants—must be reviewed for 'Change of Control' clauses. Such clauses often mandate prior written consent from third parties before ownership can be transferred, failing which valuable contracts could be terminated post-acquisition.
