OPC to Private Limited Company Conversion: Mandatory Threshold, Process and INC-6 Filing
The One Person Company structure is designed for solo entrepreneurs who want the liability protection of a company without the overhead of a multi-member structure. But the law imposes growth limits: when an OPC’s paid-up capital exceeds Rs. 50 lakh or its annual turnover crosses Rs. 2 crore, conversion to a Private Limited Company becomes mandatory within 6 months. Founders who miss this deadline face daily penalties, and the OPC continues to be classified incorrectly in ROC records, creating compliance irregularities that surface during due diligence.
This guide covers both the mandatory conversion threshold and the voluntary conversion route, the INC-6 filing process, documents required, and what changes operationally after conversion.
Key Takeaways
- Mandatory conversion when paid-up capital exceeds Rs. 50 lakh OR annual turnover exceeds Rs. 2 crore
- Conversion must be completed within 6 months of crossing the threshold
- Voluntary conversion allowed after the OPC has been incorporated for at least 2 years
- File Form INC-6 with the ROC along with altered MOA/AOA, member resolution, and nominee NOC
- After conversion: AGM required, minimum 2 directors and 2 shareholders, full annual compliance
- Penalty for non-conversion when mandatory: Rs. 10,000 + Rs. 1,000/day

Mandatory conversion threshold: when OPC must convert
Section 18 of the Companies Act 2013 read with Rule 6 of the Companies (Incorporation) Rules 2014 specifies the conditions under which an OPC is obligated to convert:
| Trigger | Threshold | Deadline to Convert |
|---|---|---|
| Paid-up share capital exceeds | Rs. 50 lakh | Within 6 months of the threshold being crossed |
| Average annual turnover exceeds | Rs. 2 crore | Within 6 months of exceeding the threshold |
Either threshold independently triggers the obligation. An OPC with Rs. 40 lakh paid-up capital but Rs. 2.5 crore turnover must convert. Conversely, an OPC with Rs. 60 lakh paid-up capital and Rs. 1 crore turnover must also convert.
Watch the paid-up capital trigger: Many OPC founders increase their paid-up capital to raise funding without realizing that crossing Rs. 50 lakh triggers mandatory conversion. If a startup OPC raises an equity round that pushes paid-up capital above Rs. 50 lakh, the 6-month conversion clock starts immediately.
Voluntary conversion: OPC’s option after 2 years
An OPC that has not crossed the mandatory thresholds can still voluntarily convert to a Private Limited Company after completing 2 years from its date of incorporation. The 2-year lock-in period was introduced to prevent promoters from using OPC as a temporary structure and then immediately converting without genuine business activity.
After 2 years, voluntary conversion is straightforward. The sole member decides to bring in additional shareholders and directors, files INC-6, and the company becomes a Private Limited Company with the same CIN and corporate history intact.
Documents required for conversion
- Altered MOA and AOA: The OPC-specific clauses (nominee director clause, single member clause, OPC restrictions) are deleted and replaced with standard Private Limited Company provisions
- Special Resolution / Written Consent of Sole Member: The sole member consents to conversion and the alteration of MOA/AOA
- No Objection Certificate from Nominee Director: The OPC’s registered nominee must give an NOC confirming they agree to the conversion
- List of proposed directors: At least 2 directors must be appointed after conversion (DSC and DIN required for each)
- List of proposed shareholders: At least 2 shareholders after conversion
- Latest financial statements: To verify whether conversion is mandatory (turnover/capital check) or voluntary
Step-by-step INC-6 filing process
- Pass member resolution: The sole member passes a resolution consenting to conversion and authorising MOA/AOA alteration. If the conversion is mandatory, document the trigger event (capital/turnover crossing).
- Obtain nominee NOC: Get a written No Objection Certificate from the nominee director named in the OPC’s MOA.
- Draft altered MOA and AOA: Prepare the new MOA and AOA for a Private Limited Company, removing all OPC-specific references.
- Appoint additional director and shareholder: The new director must obtain a DIN and DSC if they do not already have one. The new shareholder must be identified (can be an existing person or a new investor).
- File Form INC-6 on MCA V3: Log in to the MCA portal, fill Form INC-6 (Application for Conversion of OPC into Private Limited Company), attach the altered MOA/AOA, member resolution, nominee NOC, and consent letters from proposed directors. Attach the DSC of the sole member and the proposed directors.
- Pay the filing fee: Government fee for INC-6 is based on the company’s authorised capital (standard slab rates).
- ROC review and Certificate of Incorporation: The ROC reviews the application and, if satisfied, issues a fresh Certificate of Incorporation with the company’s new classification as “Private Limited Company.” The CIN remains unchanged.
What changes after conversion to Private Limited
| Item | OPC (Before) | Private Limited (After) |
|---|---|---|
| Shareholders | 1 (maximum) | Minimum 2, maximum 200 |
| Directors | Minimum 1 | Minimum 2 |
| AGM requirement | Exempt from AGM | AGM by 30 September each year |
| Annual return | MGT-7A within 60 days of FY end | MGT-7 or MGT-7A within 60 days of AGM |
| Nominee director | Required in MOA | Not required; nominee clause deleted |
| Capital raising | Restricted (single member cap) | Up to 200 shareholders, ESOP eligible |
Penalty for non-conversion
If an OPC fails to convert within 6 months of crossing the mandatory threshold:
- Company penalty: Rs. 10,000
- Continuing penalty: Rs. 1,000 per day until conversion is completed
- Officer in default: Same penalties apply to the sole member and director
