An OPC (One Person Company) lets a single Indian resident citizen register a corporate entity with limited liability — the only company structure in India that allows just one member. It requires one director, one nominee (who steps in if the member is unable to continue), and no other shareholders. An OPC must convert to a Private Limited Company once its average annual turnover exceeds ₹2 crore or paid-up capital exceeds ₹50 lakh. Registration takes 10-15 working days and costs approximately ₹9,000-₹23,000.

1. Who Is Actually Eligible for an OPC
This is the detail that trips up the most people researching OPC: only a natural person who is an Indian citizen AND a resident of India (stayed in India for 182+ days in the previous financial year) can form an OPC. This structure is not available to NRIs or foreign nationals — if you’re an NRI looking for a solo-founder structure, a single-majority-shareholder Private Limited Company is the practical equivalent, which we’ve covered in our dedicated NRI registration guide.
A person can also only be a member of one OPC at a time, and cannot simultaneously be a nominee in another OPC — this prevents someone from stacking multiple OPCs to work around the single-member limit.
2. The Nominee Requirement — What It Actually Means
Every OPC must name a nominee at the time of incorporation — someone who becomes the member of the company if the original member dies or becomes incapacitated. This isn’t a co-decision-maker or active participant in running the business; it’s purely a succession safeguard, filed via Form INC-3 with the nominee’s written consent.
A common misconception is that the nominee needs to be involved in company operations — they don’t. Many founders name a spouse, sibling, or trusted family member purely as a formality, and can change the nominee later if circumstances change, with proper filing.
3. Step-by-Step OPC Registration Process
Step 1: Obtain Digital Signature Certificate
The sole director needs a Class-3 DSC to sign the incorporation forms electronically.
Step 2: Obtain Nominee Consent (Form INC-3)
The chosen nominee must provide written consent, which is filed alongside the incorporation application.
Step 3: File SPICe+ for Incorporation
OPCs are incorporated through the same SPICe+ form used for Private Limited Companies — name reservation, incorporation, DIN, PAN, and TAN are all processed through this single integrated filing.
Step 4: Receive Certificate of Incorporation
Once approved, you receive your Certificate of Incorporation with a unique CIN, along with PAN and TAN, similar to a Private Limited Company.
4. Cost Breakdown
| Cost Item | Typical Range |
|---|---|
| DSC (1 director) | ₹1,500 – ₹2,000 |
| Name reservation (optional, RUN) | ₹1,000 |
| SPICe+ government filing fee | ₹0 – ₹500 |
| Stamp duty (state-dependent) | ₹200 – ₹5,000 |
| Professional/CA-CS fees | ₹5,000 – ₹12,000 |
| Total (typical) | ₹9,000 – ₹23,000 |
5. Mandatory Conversion — When and Why It Happens
An OPC must convert to a Private Limited Company once either of two thresholds is crossed: average annual turnover exceeding ₹2 crore over the preceding three consecutive financial years, or paid-up share capital exceeding ₹50 lakh. This isn’t optional — the conversion must be initiated within 6 months of crossing the threshold.
In practice, this makes OPC a genuinely good starting structure for a solo founder testing a business idea, with a built-in, well-defined path to a more scalable structure once the business proves itself — rather than something you need to plan around from day one.
6. OPC vs Sole Proprietorship — The Real Difference
| Factor | OPC | Sole Proprietorship |
|---|---|---|
| Liability | Limited | Unlimited personal liability |
| Legal identity | Separate from the owner | Same as the owner |
| Credibility with banks/clients | Higher — recognized corporate structure | Lower — seen as informal |
| Compliance | Moderate — annual audit, ROC filings | Minimal — GST and ITR only |
| Can convert to Pvt Ltd? | Yes, straightforward process | Requires fresh incorporation |
If you’re weighing OPC against a proprietorship purely on cost and simplicity, proprietorship wins — but if you want the credibility and liability protection of a corporate structure while still running the show solo, OPC is the closer fit.

7. Frequently Asked Questions
Q1: What is OPC registration?
A: OPC (One Person Company) registration lets a single Indian resident citizen form a corporate entity with limited liability — the only Indian company structure permitting just one member, with a mandatory nominee for succession purposes.
Q2: Can OPC have more than one director?
A: An OPC has only one member (shareholder), but it can appoint additional directors for management purposes — directors and members are distinct roles, and having multiple directors doesn’t violate the single-member rule.
Q3: When must an OPC convert to a Private Limited Company?
A: Conversion becomes mandatory once average annual turnover (over 3 consecutive years) exceeds ₹2 crore, or paid-up capital exceeds ₹50 lakh — the conversion process must be initiated within 6 months of crossing either threshold.
Q4: Can an NRI register an OPC in India?
A: No. OPC formation is restricted to natural persons who are both Indian citizens and residents of India. NRIs should consider a single-majority-shareholder Private Limited Company instead.
Q5: Who can be a nominee in an OPC?
A: Any Indian citizen and resident who consents in writing (Form INC-3) can be named as nominee. The nominee only becomes the member if the original member dies or becomes incapacitated — they have no active role otherwise.
Q6: Is audit mandatory for an OPC?
A: Yes — statutory audit is mandatory for an OPC regardless of turnover, similar to a Private Limited Company, unlike an LLP which has a turnover-based exemption.
Q7: Can a person register more than one OPC?
A: No. A person can be a member of only one OPC at a time, and cannot simultaneously serve as nominee in another OPC.
