Companies Act 2013 Basics: Meaning, Scope, and Key Definitions Explained

Updated on: March 19, 2026 by CA Bigyan Kumar Mishra

Imagine a small group of entrepreneurs planning to start a business together. They want investors, employees, and customers to trust them. But trust alone is not enough. There must be a legal framework that ensures transparency, accountability, and proper governance. This is exactly where the Companies Act, 2013 comes in.

The Act was introduced to update India’s corporate laws and match the changing business environment both within the country and globally. It replaced many earlier provisions and introduced modern corporate governance rules.

In simple words, the Act explains:

  • How a company is formed
  • How it should be managed
  • What responsibilities directors and officers have
  • How investors’ interests are protected

The law contains 470 sections and multiple schedules, divided into different chapters that deal with specific topics such as incorporation, management, auditing, and reporting.

For most beginners, understanding the preliminary chapter is the best starting point because it explains the foundation of the Act. Let’s begin with the very first section of the law. This section simply tells us three basic things:

  • What the law is called
  • Where it applies
  • When it came into force

Title of the Law

The law is officially called the Companies Act, 2013. It replaced many provisions of the earlier Companies Act, 1956 and introduced modern corporate regulations.

The law applies across the entire territory of India. This means that any company registered in India must follow its provisions, regardless of the state in which it operates.

Which Entities Must Follow the Companies Act

Many beginners assume this law applies only to companies registered under the 2013 Act. In practice, the scope is wider.

The Companies Act applies to:

  • Companies registered under the 2013 Act
  • Companies that were earlier registered under older company laws
  • Insurance companies
  • Banking companies
  • Companies involved in electricity generation or supply
  • Certain entities created through special government laws

However, if another specific law governs a particular sector and there is a conflict, the provisions of that specific law will apply for that matter.

For example, banks must follow both:

  • The Companies Act
  • The Banking Regulation Act

If there is a difference between the two rules, the banking law will take priority for banking-related matters.

Meaning of “Company” Under the Act

At the most basic level, a company is a legal entity that has been registered under the Companies Act. But the definition goes slightly further. Even companies that were registered under earlier company laws are still treated as companies under the 2013 Act.

For example, companies such as:

  • Reliance Industries
  • Tata Steel
  • Infosys

were formed years ago under earlier laws, but they still fall within the definition of a company under the current Act. This ensures continuity in the legal framework.

Understanding Authorised Capital

When a company is formed, it decides how much capital it is allowed to raise through shares. This maximum amount is called authorised capital. Think of it like setting a ceiling.

For example, suppose a company decides its authorised capital will be ₹5 crore.

This means the company cannot issue shares beyond this amount unless it formally increases its authorised capital. It does not mean the company must immediately raise ₹5 crore. It simply sets the upper limit allowed under the company’s documents.

What the Board of Directors Means

A company may have many shareholders, but the day-to-day decisions are taken by a smaller group called the Board of Directors. In simple terms, the Board is the collective group of directors responsible for managing the company’s affairs. Think of them as the strategic decision-makers.

They approve major matters such as:

  • expansion plans
  • investments
  • financial decisions
  • corporate policies

The board acts on behalf of the company while remaining accountable to shareholders.

What Are Books of Account

Every company must keep proper financial records. These records are called books of account. They include details such as:

  • money received and spent
  • goods or services sold
  • purchases made by the company
  • assets owned
  • liabilities owed

In modern practice, these records may be maintained in paper form or electronic form. Maintaining accurate books is essential because they form the basis for financial statements and audits.

Understanding Financial Statements

At the end of every financial year, companies prepare financial statements that show their financial performance. These typically include:

  • Balance sheet
  • Profit and loss statement
  • Cash flow statement
  • Statement of changes in equity
  • Notes explaining financial figures

However, smaller companies such as One Person Companies or certain small entities may not always need to include a cash flow statement. These statements help shareholders, investors, and regulators understand the company’s financial health.

What Is a Financial Year for Companies

In India, companies generally follow a financial year that ends on 31 March. For example, if a company was incorporated in June 2024, its first financial year will normally end on 31 March 2025. 

But if a company is incorporated after 1 January, its first financial year may extend until 31 March of the following year. This allows the company to prepare meaningful financial statements.

Understanding a Small Company

The law also recognizes that very large companies and smaller businesses should not be treated the same. So the Act introduces the concept of a small company. In practical terms, a company may be considered small when:

  • its paid-up share capital is relatively modest
  • its annual turnover is also within specified limits

For example, under the current rules:

  • paid-up capital may go up to around ₹4 crore
  • turnover may go up to around ₹40 crore

Companies within these limits may receive certain regulatory relaxations. However, some companies cannot be treated as small companies even if they meet these limits.

Examples include:

  • holding companies
  • subsidiary companies
  • companies governed by special laws

What Is an Associate Company?

Imagine this situation.

A large company invests in another growing business. It does not completely own the company, but it has enough influence to participate in important decisions. This is where the concept of an associate company comes in.

In simple terms, an associate company is a company in which another company has significant influence, but does not fully control it. In practice, this influence usually exists when a company controls at least 20% of the total voting power, or has the ability to participate in business decisions through an agreement.

Example

Suppose: Company A owns 25% shares in Company B.

Company A cannot run Company B completely. But it still has enough influence to participate in strategic decisions.

In this situation, Company B becomes an associate company of Company A.

Many beginners confuse associate companies with subsidiaries, but the difference is simple:

  • Associate company → influence
  • Subsidiary company → control

Who Are Key Managerial Personnel (KMP)?

In every company, some individuals hold important executive responsibilities. The Companies Act calls them Key Managerial Personnel, often abbreviated as KMP. These are the senior professionals responsible for managing the company’s operations and ensuring compliance with laws.

Typically, KMP includes:

  • Chief Executive Officer (CEO) or Managing Director
  • Company Secretary (CS)
  • Whole-time Director
  • Chief Financial Officer (CFO)

These individuals handle critical areas such as:

  • financial reporting
  • regulatory filings
  • operational management
  • governance compliance

In many Indian companies, the Company Secretary and CFO are deeply involved in ensuring the company follows the Companies Act and other regulations. When a company fails to comply with certain provisions, these officers may also be held responsible.

Understanding a Private Company

When most startups or family businesses begin operations in India, they usually choose the private company structure. A private company has three main characteristics:

  • Restriction on Share Transfer: Shares cannot be freely sold to the general public. Transfer usually requires approval within the company.
  • Limited Number of Members: The company can have up to 200 members (excluding certain employees and former employees).
  • No Public Invitation for Investment: A private company cannot invite the general public to buy its shares or securities.

What Is a Public Company?

Now imagine the same company grows over time and wants to raise a much larger amount of capital. It may convert into a public company. A public company is simply a company that:

  • is not a private company, and
  • can raise capital from the public through securities.

Public companies can list their shares on stock exchanges and allow investors to trade them.

Practical Difference:

Private CompanyPublic Company
Ownership limitedOwnership open to public
Maximum 200 membersNo such limit
Cannot invite public investmentCan raise public funds

What Is a Related Party?

In business, some transactions happen between companies or individuals who already have close relationships. These are known as related party transactions.

A related party can include:

  • a director or their relative
  • a key managerial person or their relative
  • companies connected through ownership or control
  • firms where directors are partners.

When related parties transact with each other, there is a possibility that decisions may not always be fair to the company. For example, suppose a company buys goods from another company owned by its director’s relative. The law requires additional disclosure and approvals to ensure transparency.

What Is a Subsidiary Company?

Now let’s look at a situation involving stronger control. A subsidiary company exists when another company (called the holding company) has control over it.

Control may exist when:

  • the holding company appoints or controls the majority of directors, or
  • it controls more than half of the voting power.

Suppose, Company A owns 60% shares in Company B. Because Company A controls the voting power, Company B becomes a subsidiary of Company A.

Understanding Share Capital Types

One area that confuses many beginners is different types of share capital. Let’s walk through them using a simple situation. Imagine a company plans to raise money from investors.

Authorised Capital

This is the maximum amount of share capital a company is allowed to issue, according to its memorandum.

Example: Authorised capital = ₹2 crore

The company cannot issue shares beyond this amount unless it increases the limit.

Issued Capital

This is the portion of authorised capital that the company actually offers to investors.

Example:

  • Authorised capital → ₹2 crore
  • Issued capital → ₹70 lakh

Subscribed Capital

This represents the shares that investors actually agree to purchase.

Example:

The company issues shares worth ₹70 lakh. Investors apply for shares worth ₹1 crore, but the company accepts ₹70 lakh. Subscribed capital = ₹1 crore applied.

Called-up Capital

Sometimes companies do not ask investors to pay the full share price immediately. They may collect money in stages. The amount requested from shareholders so far is called called-up capital.

Example:

Share value = ₹10

The company asks investors to pay ₹8 initially.

Called-up capital = ₹8 per share.

Paid-up Capital

This is the amount actually received by the company.

Example:

If some shareholders have not yet paid their amount, the paid-up capital will be slightly lower than called-up capital. This stage shows the actual money the company has received.

The Companies Act, 2013 forms the legal foundation for how companies operate in India. It sets out the rules for formation, management, reporting, and governance of companies. The preliminary chapter plays a crucial role because it explains:

  • the scope of the Act
  • where it applies
  • key definitions used throughout the law

For beginners, understanding these basics makes it much easier to learn the rest of company law step by step. If you are studying corporate law or planning to start a company, spending time on these foundational concepts will make the entire subject much clearer.
