Key Definitions Under Companies Act 2013 That Every Business Owner Must Know

VS Vikas Sharma 📅 March 23, 2026 ⏱️ 7 min read 👁️ 0 views Updated: Mar 25, 2026

Why Definitions Matter in Company Law

Section 2 of the Companies Act 2013 contains over 90 definitions that form the foundation of the entire Act. Understanding these definitions is not just an academic exercise -- they directly impact your compliance obligations, tax planning, and legal rights as a business owner.

For example, whether your company qualifies as a "small company" determines whether you need 2 or 4 board meetings per year. Whether someone is a "related party" determines whether a transaction needs Board or shareholder approval. Whether a person is an "officer who is in default" determines whether they face personal penalties for company violations.

This article covers the most important definitions that every director, company secretary, and business owner must understand.

Key Principle
Section 2 begins with: "In this Act, unless the context otherwise requires..." This means these definitions apply throughout the entire Act unless a specific section provides a different meaning. Always check if a section has its own definition before applying the Section 2 definition.

Company and Related Definitions

"Company" -- Section 2(20)

"company means a company incorporated under this Act or under any previous company law."
-- Section 2(20)

This means only entities registered with the Registrar of Companies under the Companies Act qualify as a "company." Partnerships, LLPs, sole proprietorships, trusts, and societies are NOT companies under this definition.

"Body Corporate" -- Section 2(11)

"body corporate or corporation includes a company incorporated outside India, but does not include -- (i) a co-operative society registered under any law relating to co-operative societies; and (ii) any other body corporate (not being a company as defined in this Act), which the Central Government may, by notification, specify in this behalf."
-- Section 2(11)

This is a wider term than "company." It includes foreign companies but excludes co-operative societies. The distinction matters because some sections of the Act apply to "body corporates" (wider scope) while others apply only to "companies" (narrower scope).

People and Roles

"Director" -- Section 2(34)

"director means a director appointed to the Board of a company."
-- Section 2(34)

Simple but crucial. Only a person formally appointed to the Board is a "director." This has implications for liability -- if you are acting as a director without being formally appointed, you may still be treated as a "deemed director" for penalty purposes, but the compliance obligations technically apply to appointed directors.

"Key Managerial Personnel" (KMP) -- Section 2(51)

"key managerial personnel, in relation to a company, means -- (i) the Chief Executive Officer or the managing director or the manager; (ii) the company secretary; (iii) the whole-time director; (iv) the Chief Financial Officer; (v) such other officer, not more than one level below the directors who is in whole-time employment, designated as key managerial personnel by the Board; and (vi) such other officer as may be prescribed."
-- Section 2(51), as amended by Companies (Amendment) Act, 2018

Why this matters: Section 203 mandates that every listed company and every public company with paid-up capital of Rs. 10 crore or more must appoint a full-time KMP (Managing Director, Company Secretary, and CFO). KMPs have specific compliance obligations and face personal penalties for defaults.

Practical Impact
If you are the CEO or CFO of a company, you are a Key Managerial Personnel by law. This means you sign the financial statements (Section 134), you are responsible for maintaining books of accounts (Section 128), and you face personal penalties if the company fails to comply. The 2018 amendment expanded KMP to include officers one level below directors, meaning senior vice presidents or general managers designated by the Board can also be KMPs.

"Officer Who Is in Default" -- Section 2(60)

"officer who is in default, for the purpose of any provision in this Act which envisages action to be taken against any officer, means -- (a) whole-time director; (b) key managerial personnel; (c) where there is no key managerial personnel, such director or directors as specified by the Board; (d) any person who, under the immediate authority of the Board or any key managerial personnel, is charged with any responsibility including maintenance, filing or distribution of accounts or records..."
-- Section 2(60)

This is the definition that determines who goes to jail or pays fines when a company violates the Act. The hierarchy is clear: first, whole-time directors and KMPs are liable. If there is no KMP, the Board can designate specific directors. And if even that is not done, the directors specified by the Board, or all directors who participated in the relevant Board meeting, are liable.

"Related Party" -- Section 2(76)

This is one of the most important definitions for corporate governance. A related party includes directors, KMPs, their relatives, and companies in which they have significant interest. Any transaction with a related party must comply with Section 188 (which requires Board or shareholder approval depending on the size of the transaction).

Example: If a company rents an office building owned by its director's wife, this is a "related party transaction." It must be disclosed in the Board report, approved by the Board (and shareholders if above prescribed thresholds), and conducted at arm's length price.

Financial Definitions

"Net Worth" -- Section 2(57)

"net worth means the aggregate value of the paid-up share capital and all reserves created out of the profits, securities premium account and debit or credit balance of profit and loss account, after deducting the aggregate value of the accumulated losses, deferred expenditure and miscellaneous expenditure not written off..."
-- Section 2(57), as amended by Companies (Amendment) Act, 2018

Net worth is used as a threshold for several compliance requirements -- CSR applicability (net worth of Rs. 500 crore triggers CSR under Section 135), eligibility for accepting deposits, managerial remuneration limits, and more.

Simple formula: Net Worth = Paid-up Capital + Reserves (from profits) + Securities Premium -- Accumulated Losses -- Deferred Expenditure

"Turnover" -- Section 2(91)

"turnover means the gross amount of revenue recognised in the profit and loss account from the sale, supply, or distribution of goods or on account of services rendered, or both, by a company during a financial year."
-- Section 2(91), as substituted by Companies (Amendment) Act, 2018

Turnover determines Small Company classification, CSR applicability, audit thresholds, and many other compliance requirements. The 2018 amendment clarified that turnover means "gross revenue recognised" rather than just "aggregate value of realisation," aligning it with Ind-AS accounting standards.

"Financial Statement" -- Section 2(40)

Financial statements include: (i) balance sheet, (ii) profit and loss account (or income and expenditure account for non-profit companies), (iii) cash flow statement, (iv) statement of changes in equity, and (v) explanatory notes.

Exemption for Small Companies
The proviso to Section 2(40) states that financial statements of One Person Companies, Small Companies, and Dormant Companies may NOT include the cash flow statement. This is a significant compliance relief -- preparing a cash flow statement requires additional accounting effort and professional fees.

Governance Definitions

"Independent Director" -- Section 2(47)

An independent director is defined by reference to Section 149(6), which provides detailed criteria. In simple terms, an independent director is a non-executive director who has no material or pecuniary relationship with the company, its promoters, or directors, and who brings independent judgment to the Board.

Every listed company must have at least one-third of its directors as independent directors. Certain unlisted public companies with paid-up capital above Rs. 10 crore, turnover above Rs. 100 crore, or aggregate outstanding loans above Rs. 50 crore must also appoint at least 2 independent directors.

"Promoter" -- Section 2(69)

A promoter is a person who has been named in the prospectus or identified in the annual return, or who has control over the affairs of the company directly or indirectly. Promoters have significant disclosure obligations and can be held liable for misstatements in the prospectus.

Important Definitions Added/Modified by Recent Amendments

"Significant Beneficial Owner" -- Section 90

While not in Section 2, this concept (introduced by the Companies (Amendment) Act, 2017 and detailed in the Companies (Significant Beneficial Owners) Rules, 2018) is critically important. Every individual who holds beneficial interest of at least 10% in shares, or who exercises significant influence or control over a company, must file a declaration with the company. This is India's equivalent of the global beneficial ownership transparency movement.

"Small Company" Revised Definition (December 2025)

As discussed earlier, MCA Notification G.S.R. 880(E) dated 1st December 2025 has increased the thresholds to Rs. 10 crore paid-up capital and Rs. 100 crore turnover. The Companies (Restriction on Number of Layers) Rules, 2017 also added the definition of "layer" for subsidiary restrictions.

Practical Advice
Keep a printed/digital copy of Section 2 definitions handy. When you read any other section of the Act, always cross-reference the definitions. For example, when Section 185 says "loan to directors," check the definition of "director" in Section 2(34), "relative" in Section 2(77), and "key managerial personnel" in Section 2(51) to understand the full scope of the prohibition. our compliance team maintains updated definition charts for quick reference.
