A private company restricts share transfers, can't invite the public to subscribe, and needs 2 directors and 2 members (max 200). A public company needs 3 directors and 7 members, can raise money from the public, and has more compliance: independent directors and committees above set limits.

Who can form an OPC?

Any natural person who is an Indian citizen, including an NRI who stayed in India at least 120 days in the previous financial year. A person can form only one OPC and must name a nominee.

What is PTC in a CIN?

PTC means a private limited company. PLC is a public limited company, OPC is a one person company and NPL is a Section 8 (not-for-profit) company.

What is INC-20A?

The declaration of commencement of business. Every company with share capital must file it within 180 days of incorporation, confirming that subscribers have paid for their shares. Late filing attracts a penalty, and the ROC can strike the company off.

Is there a minimum capital to start a company?

No. Minimum paid-up capital was removed in 2015. You can start with any amount, even ₹1,000 split among the subscribers.

What is an LLP and how is it different from a company?

A Limited Liability Partnership combines a partnership's flexibility with limited liability. It needs 2 designated partners, has no share capital, files Form 11 and Form 8 every year, and needs an audit only if turnover exceeds ₹40 lakh or contribution exceeds ₹25 lakh.
