One member, full control, limited liability.
A One Person Company (OPC), defined under Section 2(62) of the Companies Act, 2013, is a private company with a single member who owns 100% of the shares. Its defining feature is the nominee - a person named at incorporation (via Form INC-3) who steps into ownership if the member dies or becomes incapacitated. That nominee mechanism gives an OPC perpetual succession, so unlike a proprietorship it survives its owner. An OPC's name ends with '(OPC) Private Limited'.

Eligibility to register an OPC in Kolkata.
The Companies Act sets strict conditions on who can form an OPC - all must be satisfied.
A natural person only
No company, LLP, HUF, trust or other entity can be the member - only a living individual.
An Indian citizen
The sole member must be an Indian citizen; a foreign national cannot hold OPC membership.
Resident in India
The member must have stayed in India at least 120 days in the preceding financial year (reduced from 182 by the 2021 amendment).
A nominee via Form INC-3
An Indian-citizen nominee must give written consent to take over on the member's death or incapacity.
One OPC per person
An individual can be the member of only one OPC and the nominee of only one OPC at a time.
Registered office & unique name
A valid local office and a unique name ending with '(OPC) Private Limited'.
Why choose an OPC.
- Limited liability - your personal assets are protected; a proprietorship exposes them fully.
- Separate legal entity and perpetual succession - the company owns its assets and survives via the nominee.
- Lighter than a Pvt Ltd - no AGM required and relaxed board-meeting rules, so recurring compliance is typically 15-25% cheaper to run.
- Since the 2021 amendment: NRIs who are Indian citizens can incorporate an OPC, the residency threshold dropped to 120 days, and mandatory conversion on crossing ₹50 lakh capital / ₹2 crore turnover was removed.
The honest trade-off
An OPC is not compliance-free: a statutory audit is mandatory every year regardless of turnover, and it is taxed at corporate rates. It also cannot bring in equity investors. If you plan to raise venture funding, choose a Pvt Ltd; if you have partners, consider an LLP.

Two things founders get wrong about OPCs
"An OPC doesn't need an audit" - it does, a statutory audit by a CA is compulsory every year whatever the turnover. And "I must convert once I cross ₹2 crore turnover" - not since 2021; the mandatory conversion threshold was removed. You convert only when it benefits you.
