One Person Company (OPC) Registration by Sigma Solutions

Introduction
In mid-2020, a dynamic 26-year-old entrepreneur came up with an innovative idea for a digital marketing startup offering AI-based solutions for small businesses and influencers. He was ready to launch but needed a business structure that allowed him to operate legally as a single owner, while protecting his personal assets and presenting a professional front to clients, banks, and investors.
After comparing Sole Proprietorship, Private Limited Company, and One Person Company (OPC) models, he chose the OPC structure under the Companies Act, 2013, as it offered him:
- Full control of the business as the sole shareholder and director
- Limited liability protection for personal assets
- Eligibility for government tenders, funding, and tax registrations
However, the legal and compliance complexities seemed daunting. That’s where Sigma Solutions stepped in with a tailored solution.
Challenges Faced by the Founders
Despite his marketing skills, the founder faced multiple structural and regulatory challenges:
1. Business Structure Confusion
He wasn’t sure:
- Whether to choose OPC or Sole Proprietorship
- What legal and tax benefits an OPC would offer
- How compliance and annual filings worked
2. Documentation & Legal Formalities
The entrepreneur struggled with:
- How to obtain Digital Signature Certificate (DSC)
- Applying for Director Identification Number (DIN)
- Drafting and filing Memorandum of Association (MoA) and Articles of Association (AoA)
3. Nominee Director Requirement
According to Section 3(1) of the Companies Act, 2013, an OPC must appoint a Nominee Director to assume control in case of death or incapacity of the owner. He faced:
- Difficulty in identifying a trustworthy nominee
- Uncertainty about how to legally formalize nominee consent
4. Taxation, GST & Banking Concerns
The entrepreneur was unaware of:
- Whether GST registration was mandatory for his services
- How to ensure tax compliance, PAN/TAN filing, and professional tax registration
- Steps involved in opening a corporate current account
