Types of Companies under the Companies Act, 2013

Private, public, OPC, Section 8, government and more — a clear guide to choosing the right company structure.

At a Glance

      The Companies Act, 2013 classifies companies mainly on the basis of size, number of members, liability of members, and control.

      The most common forms used by startups and MSMEs are Private Limited Company and One Person Company (OPC).

      Choice of structure affects compliance burden, fundraising ability, and personal liability of promoters.

 

One of the first decisions any entrepreneur must make is which type of company to register. The Companies Act, 2013 provides for several structures, each suited to a different scale of business, ownership pattern and compliance appetite. Picking the wrong structure early on can mean unnecessary compliance costs or, conversely, restrictions on fundraising later. This guide walks through the major classifications recognised under the Act.

Classification on the Basis of Liability

Company Limited by Shares

The liability of members is limited to the unpaid amount on the shares held by them. This is by far the most common structure for commercial businesses.

Company Limited by Guarantee

Members undertake to contribute a fixed amount in the event of winding up. Commonly used for clubs, trade associations and non-profit bodies.

Unlimited Company

Members have unlimited liability for the company's debts, extending to their personal assets. Rarely used in practice today.

Classification on the Basis of Number of Members

Private Company (Section 2(68))

      Minimum 2, maximum 200 members (excluding present and former employee-members).

      Restricts the right to transfer shares.

      Prohibits any invitation to the public to subscribe for securities.

      Must use the words 'Private Limited' in its name.

Public Company (Section 2(71))

      Minimum 7 members, no maximum limit.

      Shares are freely transferable.

      Can raise capital from the public through an IPO, subject to SEBI regulations if listed.

      Minimum 3 directors are required.

One Person Company – OPC (Section 2(62))

Allows a single individual to incorporate a company with limited liability, combining the benefits of a sole proprietorship with those of a corporate structure.

Classification on the Basis of Control

      Holding Company — controls the composition of the Board or holds a majority of shares in another company (the subsidiary).

      Subsidiary Company — controlled by a holding company.

      Associate Company — a company in which another company has significant influence (generally 20% or more of total voting power) but which is not a subsidiary.

Other Special Categories

Section 8 Company (Not-for-Profit)

Formed for promoting commerce, art, science, sports, education, research, social welfare, religion, charity, environment protection, etc. Profits, if any, must be applied only towards its objects, and dividends cannot be paid to members. It enjoys certain exemptions from standard compliance requirements but needs a special licence from the Central Government (delegated to the Regional Director).

Government Company (Section 2(45))

A company in which not less than 51% of the paid-up share capital is held by the Central Government, State Government(s), or jointly by both.

Foreign Company (Section 2(42))

A company incorporated outside India which has a place of business in India, whether by itself or through an agent, physically or through electronic mode, and conducts business in India in any other manner.

Producer Company

A company formed by primary producers (farmers, growers) for activities relating to production, procurement, harvesting, and marketing of primary produce, governed under a special chapter inserted into the Act.

Small Company (Section 2(85))

A private company (other than a holding/subsidiary, Section 8 company, or one governed by a special act) with paid-up capital and turnover below prescribed thresholds — revised upward with effect from December 2025 to widen the pool of companies eligible for reduced compliance.

Illustration

Example

A group of 3 friends wants to start a technology consulting business and plans to raise venture capital in 2 years. A Private Limited Company is the natural choice — it allows equity fundraising, limited liability, and easier ESOP structuring than an LLP or OPC. In contrast, a single freelance consultant who does not plan to add co-founders soon may prefer an OPC for simplicity, converting to a private company once turnover crosses the prescribed threshold.

 

Practical Compliance Checklist

      List your fundraising plans for the next 2-3 years before choosing between OPC, private, or public company.

      Check whether your business activity qualifies for Section 8 (non-profit) benefits if the purpose is charitable.

      Confirm the number of promoters available — OPC needs 1, private company needs at least 2.

      If forming a holding-subsidiary structure, map out control percentages carefully to avoid unintended 'associate company' classification.

      Reassess your classification each year against the revised small company thresholds to claim eligible relaxations.

      For Producer Companies or Section 8 companies, budget extra time for the additional licensing/registration steps.

 

Common Mistakes Companies Make

      Registering as a public company without a real need for public fundraising, taking on unnecessary compliance.

      Assuming a 'small company' can also be a public company — the classification is exclusive to private companies.

      Ignoring the OPC-to-private conversion planning until an investor deal is already in progress.

      Overlooking that a subsidiary can also independently qualify as an 'associate company' of a different entity under certain shareholding patterns.

Frequently Asked Questions (FAQs)

Q1. Can a private company be converted into a public company?

Yes, by passing a special resolution, altering the MOA and AOA, and complying with the minimum member/director requirements of a public company, followed by filing the necessary forms with the ROC.

Q2. Is there a maximum number of members for a public company?

No, a public company can have any number of members above the minimum of 7.

Q3. Can an OPC be converted to a private company?

Yes, an OPC can convert voluntarily or is required to convert once it crosses the prescribed paid-up capital or turnover thresholds, by following the procedure under the Companies (Incorporation) Rules, 2014.

Q4. What is the key difference between a Section 8 company and a trust?

A Section 8 company is a corporate body registered under the Companies Act with a formal governance structure and MCA oversight, while a trust is governed by trust law/state registration and generally has simpler, less standardised governance.

Q5. Does a small company enjoy any compliance relaxations?

Yes — small companies enjoy relaxations such as no cash flow statement requirement, fewer board meetings (2 a year), abridged annual return (MGT-7A), and lower penalties for many defaults.

Q6. What is the difference between a holding company and a parent company?

Under Indian company law, 'holding company' is the defined statutory term used in Section 2(46); 'parent company' is generally used informally or under accounting standards (Ind AS) to mean the same concept of a controlling entity.

Q7. Can a Section 8 company be converted into a regular private or public company later?

Conversion of a Section 8 company is permitted but is a more restrictive process requiring Central Government (Regional Director) approval and satisfaction that the conversion won't harm the objects for which the licence was granted.

Q8. Is a foreign company required to incorporate a separate Indian entity to do business here?

Not always — a foreign company can operate through a registered branch/liaison/project office under FEMA regulations, or it can incorporate a wholly-owned Indian subsidiary, depending on its business strategy and regulatory approvals needed.

Conclusion

Choosing the right company type is a strategic decision, not just a formality. Entrepreneurs should weigh fundraising plans, number of promoters, compliance capacity and long-term goals before deciding between a private company, OPC, public company or a special category such as Section 8. The Act's flexible framework allows conversion between structures as the business grows, so the initial choice need not be permanent.
