What is OPC?

Also called: One Person Company

A One Person Company is a private limited company with a single shareholder, giving a solo founder limited liability and a corporate identity without needing a second member.

The single member must be a resident Indian citizen and must nominate someone to take over if they die or become incapacitated. One person can be the member of only one OPC.

An OPC must convert to a private limited company once paid-up capital exceeds ₹50 lakh or average turnover over three years exceeds ₹2 crore.

Why it matters

It gives a sole founder the credibility and liability protection of a company, which a proprietorship cannot — at the cost of company-level compliance.

Not to be confused with

These get used interchangeably, including by tools that should know better. They are different things.

Sole proprietorship

A proprietorship is not a separate legal person and the owner's liability is unlimited. An OPC is a company with limited liability, and the difference is the whole point of choosing one.

Private limited company

An OPC has one member; a private limited company needs at least two. An OPC also cannot convert into a Section 8 company or carry on non-banking financial activity.

Questions people ask

Why does an OPC need a nominee?

Because a company with one member would otherwise have no one to hold the shares if that member dies or becomes incapable. The nominee steps in, which is what allows the company to survive its only owner.

Do I still have to convert once I grow?

Not since the 2021 amendment removed the ₹2 crore turnover and ₹50 lakh capital triggers. Conversion is now voluntary, though it becomes necessary the moment you want a second shareholder.

What usually goes wrong

Choosing an OPC while intending to bring in a co-founder, which requires conversion first
Treating it like a proprietorship and skipping board and annual filings
Naming a nominee without obtaining written consent in Form INC-3
Incorporating a second OPC, which the rules do not permit
