Starting your entrepreneurial journey as a solo founder is exciting—but also comes with legal responsibilities. For many individuals, incorporating a One Person Company (OPC in India offers the perfect blend of limited liability, brand credibility, and simplified compliance compared to traditional private limited companies. However, simplified doesn’t mean “no compliance.” Missing deadlines for annual filings, GST returns, or tax submissions can result in penalties, late fees, or even legal action. This guide provides a Startup Compliance Calendar specially designed for solo entrepreneurs managing OPCs, so you always know what to file, when to file, and under which law.
An OPC allows a single individual to run a company with the benefits of corporate status.
Some key features include:
Single owner and single nominee.
Limited liability protection for personal assets.
Easier compliance compared to private limited companies.
Annual filings still mandatory under the Companies Act, 2013.
✅ Avoid penalties (ROC penalties can go up to ₹100 per day for late filings).
✅ Maintain investor trust through a clean compliance record.
✅ Be ready for any government or tax audit.
✅ Save money by avoiding interest on overdue taxes.
