Courtroom Clarity: Distinguishing limited liability in case of Sole Proprietorship and OPC

November 3, 2025

Introduction.

Ever since the evolution of entrepreneurship, the sole proprietorship is the most prominent form of business. Post enactment of Companies Act 2013, this traditional form of business has got a new and advanced version called, one person company (OPC). even though at a first glance, both appear similar, as each is managed and owned by a single individual. However, the legal and financial implications of the two forms are significantly different.

Recently, the Bombay High Court in one of its judgments, highlighted the difference between both these types of entities, and elaborated upon the limited liability feature of the one person company. In this article, we shall try to understand more about the characteristics of an OPC and sole proprietorship in the backdrop of the latest Bombay High Court judgment.

Concepts of Sole proprietorship and OPC.

In order to understand the difference between a sole proprietorship and an OPC, we must first understand the basic concepts of both these types of entities. As far as a sole proprietorship is concerned, it is the oldest and most basic form of business, whereas the advanced and evolved form of Sole proprietorship is a One Person Company incorporated under Companies Act 2013.

Sole proprietorship:

The meaning of the concept of sole proprietorship is appropriately elucidated by The Honourable Delhi High Court in its judgment in the matter of Ashok Transport Agency v. Awadhesh[i] in the following words. “A proprietary concern is only the business name in which the proprietor of the business carries on the business. A suit by or against a proprietary concern is by or against the proprietor of the business. In the event of the death of the proprietor of a proprietary concern, it is the legal representatives of the proprietor who alone can sue or be sued in respect of the dealings”

One person company

As the name suggests, a One Person Company (OPC) is a joint stock company incorporated under the provisions of the companies Act 2013. The only difference is that an OPC unlike other companies, has only one shareholder and one director. An OPC is incorporated as a private company with acronym OPC in its name and enjoys all the characteristics of a company incorporated under the Companies Act.

This concept was first time introduced by the Company Law Committee report of J. J. Irani Committee published in the year 2005. The committee  gave the following rationale for introduction of this concept in the Companies Act.

“With increasing use of information technology and computers, emergence of the service sector, it is time that the entrepreneurial capabilities of the people are given an outlet for participation in economic activity. Such economic activity may take place through the creation of an economic person in the form of a company. Yet it would not be reasonable to expect that every entrepreneur who is capable of developing his ideas and participating in the market place should do it through an association of persons. We feel that it is possible for individuals to operate in the economic domain and contribute effectively. To facilitate this, the Committee recommends that the law should recognize the formation of a single person economic entity in the form of ‘One Person Company’. Such an entity may be provided with a simpler regime through exemptions so that the single entrepreneur is not compelled to fritter away his time, energy and resources on procedural matters.”

Key differences between sole proprietorship and OPC.

The main similarity between a One Person Company (OPC) and a Sole Proprietorship is straightforward. Only a natural person can start one. The law is clear that an OPC must be formed by a single, natural person, not by another company. Likewise, a sole proprietorship is simply a business owned and run by one individual. But that’s where the similarities end. This single point of similarity gives way to three critical legal differences. Unlike a sole proprietorship, an OPC has a separate legal identity, meaning it can own property and sue or be sued in its own name. This leads to perpetual succession, allowing the company to exist even after the owner’s death, and most importantly, it provides the owner with limited liability, which protects their personal assets from business debts.

How Courts View the Difference?

The honorable Kolkata High Court has elaborated the feature of unlimited liability of a sole proprietorship in one of its latest judgments, in following words.

“A single proprietorship’s income is the money made by its owner. For taxation purposes also, a sole owner reports single proprietorship income, losses and costs. The identification of the owner or single proprietor, in this most fundamental legal structure for a company entity, is the same as the identity of the company entity. As a result, the entity’s owner is entirely responsible for all obligations the firm may incur. There is no legal separation between the business owner and the business itself; the owner is personally liable for all business debts and obligations. The owner and the business are legally considered one and the same. As a result of this single entity status, the proprietor bears unlimited liability for all business debts and losses.[ii]

The owner is therefore personally responsible for all business debts and obligations, facing unlimited liability.

In Contrast, The honorable Bombay High Court in the matter of Innovative Film Academy Private limited (OPC) vs Endemol India Private Limited[iii] wherethere was a dispute regarding payment of money due for services \ An arbitration award was passed by the arbitral tribunal ordering the deposit of the disputed amount by the OPC and its owner in a separate fixed deposit account till the conclusion of the case.

This award was challenged by the OPC before the Bombay High Court stating that, it was incorrect to order the owner of the OPC to deposit the amount due from OPC in a fixed deposit account, as the liability of the owner is separate from that of the OPC. The Bombay High Court agreed with this argument and held as follows:

Innovative was inherently an OPC, which, by law may have just one director and by law must have only one shareholder. The OPC is meant to be the business and social alter ego of the OPC, and that is by legal design. The legal framework explicitly protects such sole shareholder by limiting the liability as for any other company. If the director signing on behalf of the OPC is reason enough to wish away the statutory scheme of limited liability, it would render the very framework of the OPC redundant and otiose.”

Conclusion.

The distinction between a sole proprietorship and an OPC lies in their very foundation—while the former merges the identity of the owner with the business, the latter separates them, ensuring limited liability and perpetual existence. The judicial recognition of these differences, particularly the protection offered under the OPC structure, underscores its significance as a modern alternative to the traditional sole proprietorship, giving entrepreneurs a safer and more sustainable vehicle for business
