What is a One Person Company (OPC)?

A One Person Company (OPC) is a business structure that allows a single entrepreneur to operate a company while enjoying the benefits of limited liability. It's a hybrid model, offering the simplicity of a sole proprietorship combined with the legal credibility of a private company. Every OPC must have a nominee who can take over if the owner is unable to continue the business.

With recent legal changes, OPCs are more flexible than ever. Previously, only Indian residents could register an OPC under Section 2(62) of the Companies Act, 2013. But after the 2021 amendment, Indian citizens (including NRIs) who stayed in India for at least 120 days in the previous year can also set up an OPC.

After the 2021 amendment, now OPCs don’t have to convert into private companies when their capital crosses ₹50 lakh or turnover exceeds ₹2 crore. Additionally, OPCs can now switch to private or public companies immediately, without waiting for two years.

Fact: An OPC is restricted to having just one shareholder and one director, and interestingly, the same individual can act as both.

Why is Kolkata a Preferred Choice for OPC Registration?

Kolkata, historically a major commercial and cultural center, is re-emerging as a significant economic hub, offering a compelling alternative for OPC registration. The city has a rich history of commerce and industry, now blending its traditional strengths with a growing startup ecosystem.

1. Sector-Specific Growth & Business Focus

Kolkata's economy is a dynamic blend of traditional and modern industries, offering unique opportunities for OPCs.

  • IT and Tech: Known as the Silicon Valley of Eastern India, in the past, Kolkata has revitalized its IT sector. The city's tech parks, like those in Salt Lake City (Sector V) and New Town, are home to both established IT giants and a burgeoning number of tech startups.
  • Manufacturing and Engineering: Kolkata and its surrounding industrial belt have a strong legacy in heavy machinery, engineering, and manufacturing. OPCs in this sector can leverage a well-established industrial base, a skilled workforce, and a robust supply chain.
  • Logistics and E-commerce: 
    • Kolkata is a major port city on the eastern coast, making it a strong logistics hub.
    • Supports domestic as well as international trade smoothly.
    • Serves as a gateway to Northeast India and neighbouring countries like Bangladesh, Bhutan, and Nepal.

2. Compliance for OPCs in Kolkata

All OPCs in Kolkata fall under the jurisdiction of the Registrar of Companies (ROC), West Bengal. Compliance is straightforward with standardized forms for all OPCs across India.

West Bengal also offers a supportive business environment through policies like the West Bengal State Startup Policy, which has been succeeded by the Startup Bengal initiative. It is designed to encourage and nurture new ventures, complementing national initiatives like Startup India.

3. Local Business Ecosystem

Kolkata's entrepreneurial ecosystem is expanding rapidly, providing crucial support for new businesses.

  • Funding Networks: The city has a growing number of angel investors, venture capital firms, and private equity funds. Organizations like the Indian Angel Network (Kolkata chapter) and TiE Kolkata are actively involved in mentoring and funding promising startups.
  • Incubators & Accelerators: IIM Calcutta Innovation Park, NASSCOM's 10,000 Startups program, and various university-led incubators provide critical resources and mentorship for early-stage companies.
  • Events & Exhibitions: Regular events like the Kolkata Startup Fest and TiEcon Kolkata connect entrepreneurs with investors, potential partners, and global mentors. It fosters a vibrant and collaborative business community.

Benefits of Registering an OPC in Kolkata

Starting an OPC in Kolkata comes with multiple advantages that support growth and long-term stability:

  • Separate Legal Entity & Limited Liability: An OPC creates a distinct legal identity, protecting the personal assets of the owner. The liability is restricted to the capital invested, ensuring financial safety even in challenging times.
  • Credibility with Banks, NBFCs & Investors: A registered OPC creates credibility with banks, NBFCs, and investors, making it easier to access loans in Kolkata’s supportive business environment. However, equity fundraising remains limited since an OPC can have only one shareholder. For larger funding needs, conversion into a Private Limited Company is a better choice.
  • Quick Decision-Making & Flexibility: With only one shareholder and director, the business can implement decisions quickly. It also allows it to respond faster to opportunities and market demands.
  • Workspaces & Business Infrastructure: From Salt Lake Sector V to New Town Rajarhat, Kolkata, offers affordable office spaces, co-working hubs, and SEZs. These hubs provide modern facilities, strong connectivity, and lower operational costs compared to other metros.
  • Export & Logistics Advantage: With Netaji Subhas Chandra Bose International Airport and the Kolkata Port Trust, the city serves as the trade gateway of Eastern India. Container depots and logistics parks further support OPCs in reaching global markets through an Import Export Code (IEC).
  • Sector-Specific Growth Opportunities:
    • IT & Fintech: Strong IT presence and fintech startups make it ideal for tech-driven businesses.
    • Healthcare & Pharma: Leading hospitals such as Apollo Gleneagles and AMRI, along with pharmaceutical companies, create scope for health-tech and pharma ventures.
    • Education & EdTech: As home to premier institutes like IIT Kharagpur, Jadavpur University, and IIM Calcutta, Kolkata supports education-focused startups and EdTech platforms.
    • Manufacturing & Textiles: The city has a long-standing base in jute, textiles, and light manufacturing, offering opportunities for both traditional and modern industries.
  • Tax Advantage: Corporate tax rates apply the same as other domestic companies:
    • 22% (Section 115BAA, without exemptions/deductions).
    • 25% if turnover ≤ ₹400 Cr (otherwise 30%).
    • MAT (Minimum Alternate Tax) at 15% applies if opting for the normal regime.
  • Business Continuity & Stability: With a nominee director in place, the company’s operations continue even if the primary owner cannot manage the business. This ensures long-term stability.

If you plan to register an OPC in Kolkata, make sure you meet the eligibility criteria under the Companies Act, 2013, and use state and central policies to maximize your benefits.

Eligibility for OPC Company Registration in Kolkata

Registering a One Person Company (OPC) in Kolkata requires compliance with the Companies Act, 2013. These conditions ensure that only suitable individuals can set up an OPC while maintaining proper legal standards. Here are the criteria:

  • Single Member Structure: An OPC can be formed by just one individual who acts as both shareholder and director. OPC can have up to 15 directors.
  • Nominee Appointment: A nominee must be appointed at the time of incorporation. This nominee will step in if the sole member is unable to continue managing the company.
  • One OPC Rule: A person can register only one OPC and cannot serve as a nominee in more than one company at a time.
  • No Minimum Capital Requirement: There is no mandatory paid-up capital needed for forming an OPC in Kolkata. Earlier, forming an OPC required a minimum paid-up capital of ₹1 lakh.
  • Restricted Activities: OPCs are not permitted to carry out banking, NBFC operations, investment in securities, or function as Section 8 (non-profit) companies.
  • Registered Office: The company must have a registered office address within Kolkata for official communication with the Registrar of Companies.
  • Only Natural Persons Allowed: An OPC can only be incorporated by an individual (natural person). Other entities, like companies, LLPs, or trusts, cannot form an OPC.

How to Register a One Person Company in Kolkata?

If you are planning to start your own business as a single owner, registering a One Person Company (OPC) is one of the best ways to begin. The process is completely online and can be completed by following a few simple steps.

Step 1: Apply for DSC and DIN

You require these two before starting the registration process:

Step 2: Choose and Reserve a Company Name

Your company name must be unique and comply with the Companies Act, 2013.

  • Check availability: Use the MCA portal (mca.gov.in) to search for name availability.
  • Reserve name: Use the RUN (Reserve Unique Name) service or directly apply through SPICe+.

You can also use our company name checker to verify the availability of your chosen name.

Step 3: Draft MOA and AOA

Two key legal documents are required for incorporation:

  • Memorandum of Association (MOA): Defines the main business objectives, scope of activities, and powers of the company. MOA reflects the company’s relationship with the outside world.
  • Articles of Association (AOA): Specifies the internal rules, governance framework, and management of the company. AOA also covers decision-making, director powers, and shareholder rights.

Step 4: Appoint a Nominee

As an OPC can have only one director/shareholder, it is mandatory under Section 3(1)(c) of the Companies Act, 2013, to appoint a nominee who will step in if the sole member dies or becomes incapacitated.

  • File Form INC-3 with nominee consent and KYC documents.

Step 5: File the Incorporation Forms

Once the name is approved, proceed with Form SPICe+ (INC-32) for OPC incorporation:

  • Attachments required: DSC, DIN, MOA, AOA, proof of registered office, ID, and address proof of the director and nominee.
  • Pay fees: Includes filing fees and stamp duty (calculated based on authorized share capital and state rules).

Step 6: Get the Certificate of Incorporation

After approval, the ROC issues the Certificate of Incorporation (COI), which includes the company’s Corporate Identity Number (CIN).

  • The company’s PAN and TAN are usually allotted automatically upon incorporation.
  • COI also provides legal recognition and confirms the company’s separate legal status.

Step 7: Open a Bank Account

After receiving the incorporation certificate and PAN, open a current bank account in the name of the OPC. This account will handle all business transactions.

Since 2020, the MCA introduced the AGILE-PRO form (INC-35) alongside SPICe+, which allows you to apply for the following simultaneously:

  • EPFO – Employees’ Provident Fund Organisation
  • ESIC – Employees’ State Insurance Corporation
  • GSTIN – Goods and Services Tax Identification Number
  • Profession Tax (if applicable)
  • Bank Account

Once these steps are completed, your OPC will be legally registered, and you can begin operations with full compliance.
