Short answer: an OPC is a private limited company with one member instead of two. You get limited liability and a separate legal identity without finding a second shareholder. The catch is that you must name a nominee at incorporation, the compliance load is close to a private limited company’s, and an OPC cannot take on investors — so it suits a solo founder building a business, not one building a startup.
What an OPC actually is
It is a company under the Companies Act, 2013 with a single member. Not a separate species — a private limited company with the two-shareholder requirement relaxed.
That framing matters, because it tells you what to expect. You get the corporate benefits: limited liability, a distinct legal entity, perpetual succession, a CIN, the ability to open a current account and contract in the company’s name. You also get most of the corporate obligations: a statutory auditor from year one, annual filings with the ROC, DIR-3 KYC, income tax returns.
Who it genuinely suits
- A solo founder who wants limited liability and does not have — or want — a partner
- A consultant or professional whose clients prefer contracting with a company
- Someone who wants to separate personal assets from business risk without taking on a co-owner
Who should not choose it
Be honest with yourself here, because converting later costs time and money.
- If you will raise investment. An OPC has one member. Investors buy shares, and taking on a shareholder means converting first.
- If you will issue ESOPs. Same problem.
- If you have a co-founder already, even informally. Register a private limited company with both of you on the cap table from day one. Retrofitting a co-founder into an OPC is worse than starting right.
- If the compliance load worries you. An OPC still appoints an auditor and files annually. An LLP below the Rule 24 thresholds does not need a statutory audit — see LLP registration.

The nominee — the part people forget
Every OPC must name a nominee at incorporation, and the nominee must consent in writing.
The nominee is the person who becomes the member if you die or become incapacitated. This is not a formality. It is the mechanism that gives an OPC perpetual succession despite having one owner, and it is why the form asks for it before the company exists.
Two things follow:
- The nominee must be a natural person and must consent. Consent is filed in Form INC-3. You cannot nominate someone without telling them.
- The nominee can be changed later, and should be reviewed when your circumstances change. A nominee named at 25 may not be the right one at 40.
Choose someone who would actually be able to step in. The default choice is often a parent or spouse; the right choice is whoever could hold the thing together.
What you get
- Certificate of Incorporation with your CIN
- PAN and TAN for the company
- DIN for the director
- Digital Signature Certificate
- Memorandum and Articles of Association
- Nominee consent filed
- Form INC-20A filed — the declaration of commencement of business
The process
1. Digital Signature Certificate — 1 to 2 days
The proposed director needs one before anything can be filed.
2. Name reservation — 1 to 3 days
Through SPICe+ Part A. Your name must not clash with an existing company or a registered trademark. Submit a second choice; budget for one rejection.
3. Incorporation filing — 2 to 5 days
SPICe+ Part B, carrying the MOA, AOA, director declaration and the nominee’s consent in Form INC-3. PAN, TAN, EPFO, ESIC and the bank account request are bundled in.
4. Certificate of Incorporation — 1 to 3 days
The company legally exists from the date on the certificate.
Realistic total: 7 to 15 working days with documents in order.
After incorporation
The same obligations that apply to a private limited company start immediately:
- Form INC-20A — declaration of commencement of business, within 180 days of incorporation under section 10A. Until it is filed the company cannot legally begin operations or borrow. Non-filing carries ₹50,000 on the company plus ₹1,000 per day on each officer in default, capped at ₹1,00,000.
- First auditor — appointed by the Board within 30 days of incorporation, under section 139(6).
- Then the annual cycle: AOC-4, MGT-7A (the OPC variant of the annual return), ADT-1 and DIR-3 KYC.
Delayed annual filings carry an additional fee of ₹100 per day, per form, under section 403 read with the Companies (Registration Offices and Fees) Rules, 2014, with effect from 1 July 2018 — with no upper cap.
An OPC is exempt from holding an AGM. That is a genuine simplification, and close to the only one.

Restrictions you should know before filing
- One person can incorporate only one OPC, and can be the nominee for only one.
- A minor cannot be a member or nominee.
- An OPC cannot carry out Non-Banking Financial Investment activities, including investing in the securities of a body corporate.
- The member must be a natural person. A company cannot own an OPC.
Converting to a private limited company
An OPC can convert to a private or public limited company, and conversion is done regularly — usually when a founder takes on a co-owner or prepares to raise.
The rules on when conversion becomes mandatory were amended in 2021, and the thresholds have moved. Rather than print a figure here that may not apply to your year, we will confirm the position against the rules in force for your case. If you are approaching any scale at which this might bite, it is worth asking early rather than discovering it in an audit.
Documents you need
Member / director
- PAN card
- Aadhaar card

- Passport-size photograph
- Personal email and mobile for OTPs
Nominee
- PAN and Aadhaar
- Written consent in Form INC-3
Registered office
- Recent utility bill, within two months

A residential address is acceptable.
What it costs
| Component | What drives it |
|---|---|
| Government fees | Your authorised capital |
| Stamp duty | A state subject — the same company costs different amounts in different states |
| DSC | One, for the director |
| Professional fee | Ours. Fixed and in writing before work starts |
Because stamp duty is state-specific and government fees scale with authorised capital, there is no honest single all-India figure. We give you the split between government fees and our fee in writing before you pay anything.

Frequently asked questions
How many people do I need to register an OPC?
One member, who is also usually the director. You must additionally name a nominee, but the nominee is not an owner and holds no shares while you are alive and capable.
Is there a minimum capital?
There is no prescribed minimum paid-up capital. Authorised capital is a separate figure and affects your government fees.
Can an OPC have more than one director?
Yes. An OPC has one member, but it can have more than one director.
Does an OPC need to hold an AGM?
No. An OPC is exempt from holding an annual general meeting. The other annual filings still apply.
Can an NRI or foreign national register an OPC?
The eligibility rules on residency were amended in 2021. Ask us for the position that applies to your citizenship and residency — it is a short answer, but it depends on facts this page cannot see.
Can I convert my OPC into a private limited company later?
Yes, and it is done regularly. The rules on when conversion is mandatory were amended in 2021, so confirm the current position for your situation.
Is an OPC taxed differently from a private limited company?
No. An OPC is taxed as a company. Get specific advice on rates and treatment for your situation.
