Difference between Sole Proprietorship and One Person Company

Entrepreneurs starting a business have several options to choose from. For those wishing to establish their own ventures, Sole proprietorship and a One Person Company (OPC) are two popular choices. There are fundamental differences between both structures regarding business operations and legal obligations. In this blog, we will focus on the key differences between Sole Proprietorship and One Person Company.

What is Sole Proprietorship and One Person Company?

  • Sole Proprietorship:
    It is an unincorporated business which is owned and operated by a single individual. It is the most common, simplest form of business structure in which the owner enjoys complete control over decision-making and is personally liable for all business obligations.
  • One Person Company:
    Introduced under the Companies Act, 2013 in India, an OPC is a distinct legal entity that allows a single individual to operate as a company. Separation of personal and business assets is possible as it provides limited liability protection to the owner.

Ownership and Liability of Sole Proprietorship and OPC

Difference between Sole Proprietorship and One Person Company
  • Sole Proprietorship:
    In this complete control and ownership over the business is possessed by the owner and is personally liable for all debts, losses, and legal obligations of the business. Legal distinction between personal and business assets is absent.
  • One Person Company:
    In this the sole shareholder and director is a single individual. The owner’s personal assets are protected from the company’s liabilities, hence enjoying limited liability. This separate legal existence reduces the risk borne by the individual.

Formation and compliance of Sole Proprietorship and OPC

  • Sole Proprietorship:
    It requires no formal registration and is relatively straightforward. The business is operated by the owner under his own name, or a trade name and he need to obtain licenses and permits as per local regulations.
  • One Person Company:
    A formal process with the Registrar of Companies (RoC) is involved to register an OPC. The Memorandum of Association (MoA) and Articles of Association (AoA) need to be drafted and submitted by the owner to the RoC. Compliance obligations such as conducting annual general meetings and filing annual financial statements should be followed by the OPC.

Continuity and Transferability of Sole Proprietorship and One Person Company

  • Sole Proprietorship:
    Since a sole proprietorship is entirely dependent on the owner, it lacks perpetual existence as a business. The business entity ceases to exist in the event of the owner’s demise or decision to discontinue.
  • One Person Company:
    OPCs can outlive their owners as they are separate legal entities, leading to continuity. Transfer of ownership by selling shares or through succession planning, ensuring the business’s longevity is possible.

Fundraising and Expansion of Sole Proprietorship and OPC

  • Sole Proprietorship:
    Financing of their business by the sole proprietors is usually based on personal savings or loans. Attracting external investments or raising capital can be challenging due to limited legal structure.
  • One Person Company:
    When it comes to fundraising and expansion, OPC has an advantage. Equity shares can be issued, and funds raised from investors, making growth and scaling the business possible.


Choosing between Sole Proprietorship and One Person Company requires careful considerable evaluation of various factors. Sole proprietorship offers autonomy and simplicity but exposes the owner to unlimited liability.

On the other hand, OPCs are suitable for individuals seeking legal separation between personal and business affairs as they provide limited liability protection and more formalized structures. Evaluation of various factors such as their business goals, risk tolerance, and long term vision needs to be done before he can decide on the most appropriate venture structure.

1. What differentiates a Sole Proprietorship from a One Person Company?

Legal structure and liability are the key differentiating factors. While a sole proprietorship is an unincorporated business and personal liability for all business obligations is on the owner, a One Person Company (OPC), provides limited liability protection to the owner, separating personal and business assets, as it is a distinct entity.

2. What is the concept of liability in both structures?

The owner has unlimited liability in sole proprietorship and is personally responsible for all debts and legal obligations of the business. The owner’s liability is limited to the extent of their investment in the company, safeguarding their personal assets from business liabilities in an OPC.

3. What is the ownership structure in these business forms?

The business is solely owned and controlled by an individual. They have complete authority over decision-making and operations in Sole Proprietorship. In an OPC, the individual retains full control over the company’s affairs and is the sole shareholder and director.

4. What are the differences in the registration process and compliance requirements?

Formation and compliance are different. There is no formal registration when establishing a sole proprietorship, whereas registering an OPC involves compliance obligations, such as filing annual financial statements and conducting annual general meetings and a formal process involving the Registrar of Companies (RoC).

5. In case of the owner’s demise or retirement what is the future of the business?

Upon the owner’s demise or decision to discontinue the business ceases to exist in sole proprietorship. In contrast, OPCs can outlive their owners, ensuring business continuity and allowing for succession planning.

6. With respect to fundraising and expansion in these structures, are there any advantages?

Reliance on personal savings or loans for financing their businesses is the norm with sole proprietors. OPCs, however, can issue equity shares and attract external investments, facilitating growth and scalability.

7. For long term business growth, which structure is more suitable?

For small-scale and owner-operated businesses, sole proprietorship is suitable. A better framework for long-term growth is offered by the OPCs as they provide a more conducive atmosphere for expansion and attracting investors due to limited liability protection, perpetual existence, and capital raising ability through equity shares. 

8. Is it possible to convert a Sole proprietorship into an OPC?

Yes, a sole proprietorship can be converted into an OPC. The process of conversion involves legal compliance and necessary documents filing with the Registrar of Companies.

9. What are the tax implications specific to these structures?

Both Sole Proprietorships and OPCs are taxed as per the individual Income Tax Slab Rates. However, additional compliance obligations related to corporate taxation, such as filing annual tax returns need to be followed by the OPCs.

10. When choosing between a sole proprietorship and an OPC, what factors need to be considered?

Evaluation of factors such as liability protection, long-term business goals, growth potential, compliance requirements, funding needs, and personal risk tolerance can help you make an informed decision about the business structure that suits you the most.
