1. What Is a One Person Company (OPC)?
A One Person Company (OPC) is a distinct corporate structure introduced under Section 2(62) of the Companies Act, 2013, and operationalised in India from April 2014. It allows a single individual to own and operate a company with full limited liability protection - combining the operational simplicity of a sole proprietorship with the legal personality, credibility, and perpetual succession of a private limited company.
Before OPC was introduced, forming any company required at least two directors and two shareholders, effectively shutting out solo founders from the corporate world. OPC changed that fundamentally.
Key Characteristics
- Single shareholder and sole director (same person is permitted)
- Separate legal identity - can own assets, enter contracts, sue and be sued independently
- Limited liability - personal assets of the owner are protected from company debts
- Perpetual succession - nominee takes over in event of death or incapacity of the member
- No requirement to hold an Annual General Meeting (AGM)
- Simplified annual compliance - files MGT-7A (abridged return) instead of MGT-7
- Cannot issue shares to the public or list on a stock exchange
2. Eligibility Criteria
Before initiating OPC registration, verify that both the promoter and the proposed nominee meet the following statutory requirements:
| Criterion | Requirement |
|---|---|
| Citizenship | Must be a natural person and Indian citizen |
| Residency | Must have stayed in India for at least 120 days during the immediately preceding financial year (relaxed from earlier 182-day rule per 2021 MCA amendment) |
| Age | Must be 18 years or above (no upper limit) |
| OPC cap | One individual can form only one OPC at a time |
| Nominee | Mandatory - must be an Indian citizen and resident; cannot simultaneously be the nominee of another OPC |
| Disqualifications | Cannot be a minor, a person of unsound mind, or undischarged insolvent |
| Restricted activities | Banking, insurance, and investment (NBFC activities) cannot be carried on as an OPC |

6. Government Fees for OPC Registration
OPCs and Small Companies enjoy concessional (often zero) fee slabs under the Companies (Registration Offices and Fees) Rules, 2014 - a significant cost advantage over Private Limited Companies.
6.1 SPICe+ Incorporation Fee (OPC / Small Company Slab)
| Authorised Share Capital | OPC / Small Co. Fee | Private Ltd Fee (for reference) |
|---|---|---|
| Up to Rs 15,00,000 (Rs 15 lakh) | Rs 0 | Rs 0 (up to Rs 1L) |
| Rs 15,00,001 to Rs 25,00,000 | Rs 2,000 | Rs 4,000 |
| Rs 25,00,001 to Rs 50,00,000 | Rs 4,000 | Rs 8,000 |
| Above Rs 50,00,000 | Per MCA slab (higher) | Per MCA slab |
Note: The above is the SPICe+ registration filing fee only. MOA/AOA registration fees and stamp duty are additional and state-specific.
6.2 Additional One-Time Government Charges

| SPICe+ filing fee (up to Rs 15L capital) | Rs 0 |

8. Key Benefits of OPC Registration
- Limited liability protection: Personal assets of the sole member are fully protected from company debts and liabilities.
- Separate legal entity: The OPC can own property, open bank accounts, enter contracts, and take legal action in its own name.
- 100% ownership and control: No partners, no board politics - complete decision-making authority rests with the sole member.
- Better access to institutional credit: Banks and financial institutions are far more willing to lend to an incorporated entity than to a sole proprietor.
- Credibility and professional image: Corporate status enhances trust with larger clients, especially in B2B and government contracts.
- Simplified annual compliance: No mandatory AGM; files abridged annual return (MGT-7A) instead of the full MGT-7.
- Continuity of business: The nominee mechanism ensures business continuity even in case of the member's death or incapacity.
- Govt fee advantage: Zero SPICe+ filing fee for authorised capital up to Rs 15 lakh - significantly cheaper than a Private Limited Company.
9. Annual Compliance After OPC Registration
Registering an OPC is only the first step. Ongoing annual compliance is mandatory to maintain active status and avoid penalties.
| Filing | Purpose | Due Date | Late Fee |
|---|---|---|---|
| INC-20A | Commencement of Business Declaration | Within 180 days of COI | Rs 50,000 company + Rs 1,000/day director (if not filed) |
| ADT-1 | Auditor Appointment | Within 30 days of incorporation | Escalating daily penalties |
| AOC-4 | Filing of Financial Statements | Within 180 days from close of FY (i.e., 27 September) | Rs 100/day |
| MGT-7A | Abridged Annual Return | Within 60 days from close of FY (i.e., 28 November) | Rs 100/day |
| DIR-3 KYC | Annual Director KYC | 30 September each year | Rs 5,000 flat (after deadline) |
| Income Tax Return | ITR-6 for OPC | 31 October (if audit applicable) | Rs 5,000 flat (Section 234F) |
10. Common Challenges and How to Avoid Them
- Name rejection: Avoid names similar to existing companies, LLPs, or registered trademarks. Check MCA company search and IP India trademark database before filing.
- DSC mismatch: Ensure PAN details on DSC exactly match MCA portal records. Discrepancies cause rejection at the signing stage.
- Registered office proof errors: The address proof document must be dated within 2 months of the filing date. Many applications are rejected due to stale documents.
- INC-3 not witnessed correctly: Nominee consent must be signed before a notary or witnessed as required under MCA guidelines.
- Forgetting INC-20A: Failure to file Commencement of Business Declaration within 180 days results in severe penalties and may trigger ROC action to strike off the company.
- ADT-1 deadline missed: Under the July 2025 MCA amendment, the 15-day ADT-1 filing window is strictly enforced with daily compounding penalties.
11. Mandatory and Voluntary Conversion of OPC
11.1 Mandatory Conversion
An OPC must compulsorily convert to a Private Limited Company within 6 months of the date on which either of the following thresholds is crossed:
- Paid-up share capital exceeds Rs 50 lakh, OR
- Average annual turnover of the immediately preceding 3 consecutive financial years exceeds Rs 2 crore
11.2 Voluntary Conversion
An OPC can voluntarily convert to a Private Limited or Public Limited Company after 2 years from the date of incorporation, subject to MCA approval and shareholder/board resolution.

13. Frequently Asked Questions
Can an NRI register an OPC?
No. As of the current MCA rules, only an Indian citizen who is also a resident (stayed 120+ days in the preceding financial year) can incorporate an OPC. NRIs who do not meet the residency threshold are not eligible.
Is there a minimum capital requirement for OPC?
The minimum authorised capital is Rs 1 lakh. There is no minimum paid-up capital requirement - the company can be incorporated with Rs 1 as paid-up capital. Starting with a lower authorised capital also reduces stamp duty costs.
Can a minor be a nominee?
No. The nominee must be a major (18 years or above) Indian citizen and resident. The name of the nominee is disclosed in the MOA.
Is audit mandatory for OPC?
Yes. Unlike sole proprietorships (where audit is turnover-threshold based), a statutory audit by a Chartered Accountant is mandatory for all OPCs every financial year, regardless of turnover or capital.
What if the nominee refuses to take over after the member's death?
The nominee has the right to withdraw consent by filing INC-4. In such a situation, the legal representative of the deceased member may apply to the NCLT for directions. The company's activities are governed by the surviving nominee or legal heir pending resolution.
Can an OPC apply for a Startup India recognition?
Yes. OPCs are eligible for Startup India recognition from DPIIT (Department for Promotion of Industry and Internal Trade), provided they meet the eligibility criteria - incorporated within 10 years, annual turnover below Rs 100 crore in any year since incorporation, and working on innovation or scalable business model.
What happens if INC-20A is not filed?
If the Commencement of Business Declaration (INC-20A) is not filed within 180 days of the Certificate of Incorporation, the company cannot legally commence business operations. The Registrar may initiate proceedings to strike off the company's name from the register, and daily penalties apply.
