Starting a business as a solo entrepreneur is now more accessible than ever, thanks to the concept of One Person Company registration in coimbatore introduced under the Companies Act, 2013. This structure allows a single individual to form a corporate entity with limited liability, enabling startups to enjoy the benefits of a Private Limited Company without needing partners. However, once your OPC is incorporated, it’s crucial to meet ongoing regulatory requirements to avoid penalties and maintain active status.
This guide outlines all mandatory filings, timelines, and compliances for an OPC post-incorporation, applicable in FY 2024-25 and 2025-26, covering MCA, Income Tax, GST, and other statutory requirements.
- What is an OPC?
An OPC is a hybrid between a sole proprietorship and a private limited company. It provides the owner with the benefit of limited liability and a separate legal identity while maintaining operational simplicity.
Key characteristics of an OPC:
- Requires only one shareholder and one nominee.
- Offers limited liability protection.
- Recognized as a separate legal entity.
- Can own assets, enter contracts, and sue or be sued independently.
- NRIs (Indian citizens) can form OPCs post-2021 amendments.
- No mandatory conversion thresholds anymore—conversion is optional.

After registration, your OPC must complete certain filings within specific deadlines to maintain compliance:
