Quick answer: The Companies Act, 2013 does not prescribe any minimum paid-up capital to register a One Person Company (OPC) in India. You can incorporate an OPC with an authorised capital as low as ₹1 (in practice, most founders start at ₹1 lakh), and there is no fixed amount you’re legally required to actually invest. A separate 2021 rule change also removed the old requirement that forced an OPC to convert to a private limited company once its paid-up capital or turnover crossed a fixed threshold. The rest of this guide breaks down exactly what that means for your registration cost, your authorised-vs-paid-up capital, and what to do as your business grows.
What is a One Person Company?
A One Person Company (OPC) is a company structure defined under Section 2(62) of the Companies Act, 2013, allowing a single individual to own and run a company with limited liability, a separate legal identity, and perpetual succession without needing a co-founder or partner, unlike a private limited company (which needs at least two shareholders and two directors under Section 3(1)(c)). It sits between a sole proprietorship and a private limited company: you get full ownership and control like a proprietorship, but the legal protection and credibility of a registered company.
Is There a Minimum Capital Requirement for OPC Registration?
No. There is no minimum paid-up capital requirement for registering an OPC or any private or public company in India. This wasn’t always the case: before the Companies (Amendment) Act, 2015, private companies needed a minimum paid-up capital of ₹1 lakh and public companies needed ₹5 lakh. That amendment removed the minimum capital requirement from the definitions of both private and public companies in Section 2(68) and Section 2(71), and OPCs, being a category of private company, inherited that exemption.
In practice, this means:
- You decide how much capital to bring into the company there’s no floor amount.
- Most OPCs are still incorporated with an authorised capital of ₹1 lakh as a practical starting point, mainly because it keeps ROC incorporation fees low and gives you a credible minimum net worth for opening a current bank account and dealing with vendors.
- You can set authorised capital higher if your business plan needs it (e.g., to raise paid-up capital from the sole member later without extra ROC filings, up to the authorised limit).
Authorised Capital vs. Paid-Up Capital: What’s the Difference?
These two terms are the actual source of confusion behind “minimum capital” questions, so it’s worth understanding the authorized capital versus paid-up capital differences with examples before deciding on your initial figures:
- Authorised capital is the maximum value of shares your company is legally permitted to issue, as stated in the Memorandum of Association (MOA). It’s a ceiling, not money that has to exist in a bank account.
- Paid-up capital is the actual money the sole member has invested in exchange for shares, which can be any amount up to the authorised capital including a very small figure.
Example: If you set authorised capital at ₹1,00,000, you could choose to pay up only ₹10,000 initially and increase it later (via a board resolution and, if it crosses the authorised limit, an amendment to the MOA under Section 61) as the business needs more working capital.
ROC Fees Linked to Authorised Capital
While there’s no minimum capital requirement, your authorised capital does directly affect your MCA/ROC incorporation fee and applicable stamp duty, since both are charged on a slab basis tied to the authorised capital stated in the SPICe+/MOA filing. For a full price overview, refer to our detailed breakdown of OPC registration fees.
| Authorised Capital | Typical ROC Filing Impact |
|---|---|
| Up to ₹1,00,000 | Lowest ROC incorporation fee slab; the Central Government’s SPICe+ e-MOA/e-AOA filing fee waiver (introduced to promote ease of incorporation) also covers small-capital companies at this level. |
| ₹1,00,001 – ₹10,00,000 | ROC fee rises in slabs as authorised capital increases, up to the government’s waiver ceiling. |
| Above the waiver ceiling | Incremental ROC fee per additional slab, plus state stamp duty rises proportionately. |
Note: Stamp duty on the MOA/AOA is levied by the state where your registered office is located (under the Indian Stamp Act as adopted by each state), so the exact rupee figure varies by state of incorporation.
The 2021 Update: Mandatory Conversion Threshold Removed
Until March 2021, Rule 6 of the Companies (Incorporation) Rules, 2014 required an OPC to compulsorily convert into a private or public limited company within six months if:
- Its paid-up share capital exceeded ₹50 lakh, or
- Its average annual turnover over the preceding three consecutive financial years exceeded ₹2 crore.
The Companies (Incorporation) Second Amendment Rules, 2021 (effective 1 April 2021) omitted Rule 6 entirely. This means:
- No forced conversion: There is no longer any capital or turnover ceiling that forces an OPC to convert (see the full breakdown of OPC turnover limits and conversion rules). You can scale an OPC well beyond ₹50 lakh in paid-up capital or ₹2 crore in turnover and remain an OPC indefinitely if you choose to.
- Voluntary transitions: Conversion to a private or public limited company is now entirely voluntary, driven by your own business decision (e.g., wanting to raise external equity, which OPCs cannot do from the public) rather than a compliance deadline.
- NRI participation: The same 2021 amendment also allowed NRIs to incorporate an OPC as the sole member, reducing the residency requirement from 182 days to 120 days in the preceding financial year useful context if capital is being brought in from abroad, though FDI/NRI capital in an OPC still needs to follow FEMA/RBI reporting norms applicable to the sector.
Do Regulated or Capital-Intensive Businesses Need More Capital for an OPC?
Not exactly. An OPC doesn’t face a higher minimum capital for regulated sectors; instead, some activities are not permitted in the OPC structure at all, regardless of how much capital you bring in. Under the Companies Act and rules, an OPC cannot:
- Carry on non-banking financial investment activities, including investing in the securities of any corporate body (i.e., an OPC cannot be structured as an NBFC).
- Convert into or be incorporated as a Section 8 (non-profit) company.
- Raise capital by inviting the public to subscribe to its shares or debentures (it remains a private company for this purpose).
If your business model needs any of the above, the capital question is secondary you’d need a private or public limited company structure regardless of capital size.
Why Adequate Capital Still Matters, Even Without a Legal Minimum
“No minimum” doesn’t mean capital doesn’t matter. A reasonable starting paid-up capital still helps because:
- Banks and NBFCs typically expect a minimum net worth or paid-up capital before extending business credit or overdraft facilities.
- Vendors, government tenders, and larger clients often use paid-up capital as an informal credibility check.
- Adequate capital reduces reliance on director loans and unsecured borrowing in the first year of operations.
Increasing Capital After Incorporation
You are not locked into your original capital figures. An OPC can increase its authorised capital (by altering the MOA under Section 61) and subsequently issue further paid-up capital to the sole member, subject to filing the relevant ROC forms (Form SH-7 for authorised capital changes, along with the applicable fee for the incremental slab). There is no restriction on how many times or by how much you can increase capital as the business grows.
OPC vs. Sole Proprietorship: The Capital Angle
| Parameter | One Person Company (OPC) | Sole Proprietorship |
|---|---|---|
| Minimum capital | None required | None required |
| Legal capital structure | Authorised + paid-up capital via MOA | No formal capital concept |
| Liability | Limited to capital invested | Unlimited (personal assets at risk) |
| Credibility for funding | Higher recognised company structure | Lower no separate legal entity |
| Regulatory filing on capital changes | Required (ROC forms) | Not applicable |
Frequently Asked Questions
Is there a minimum capital required to register an OPC in India?
No. The Companies Act, 2013 does not require any minimum paid-up capital for an OPC. Most founders start with an authorised capital of ₹1 lakh as a practical benchmark, not a legal requirement.
What is the ideal authorised capital for a new OPC?
There’s no fixed “ideal” figure, but ₹1 lakh is the most common starting point because it keeps ROC incorporation costs low while still meeting typical bank and vendor credibility expectations. You can set it higher if you plan to raise significant paid-up capital soon after incorporation.
Is there a turnover limit for an OPC?
Not anymore. Before April 2021, an OPC had to convert to a private limited company if its turnover crossed ₹2 crore (averaged over three years) or paid-up capital crossed ₹50 lakh. The Companies (Incorporation) Second Amendment Rules, 2021 removed this mandatory threshold, so an OPC can now operate at any turnover level and convert only if the owner chooses to.
What is the minimum number of directors required for an OPC?
An OPC needs a minimum of one director, who can also be the sole shareholder. It can have up to 15 directors under Section 149, but only one shareholder/member regardless of director count.
Can an OPC be classified as a “small company”?
An OPC can meet the financial thresholds for a “small company” under Section 2(85) (paid-up capital up to ₹4 crore and turnover up to ₹40 crore), and in practice already receives several of the same compliance exemptions as a small company — such as holding only two board meetings a year and simplified annual return signing directly under the OPC rules, regardless of its size.
Does increasing capital in an OPC trigger mandatory conversion to a private limited company?
No, not since April 2021. You can increase capital and turnover without any forced conversion; conversion is entirely at your discretion.
Can NRIs invest capital in or set up an OPC?
Yes. Since the 2021 amendment, a Non-Resident Indian can be the sole member of an OPC (residency requirement reduced to 120 days in the preceding financial year), subject to appointing a resident director and following applicable FEMA/RBI norms for any foreign-sourced capital.
What happens to unpaid authorised capital is it a compliance risk?
No. Authorised capital that hasn’t been issued as paid-up capital carries no penalty or compliance obligation; it simply represents unused headroom to issue more shares later without amending the MOA.
Conclusion
The short answer to “how much capital do I need for an OPC” is: none, legally. What actually matters is choosing a sensible authorised capital figure for cost and credibility reasons, understanding that the old ₹50 lakh/₹2 crore mandatory conversion rule no longer exists, and knowing that certain regulated activities are restricted by structure rather than by capital size. If you’re incorporating an OPC and want the capital structure authorised capital, paid-up capital, and future increases set up correctly from day one, Kanakkupillai’s company registration team can handle the filing end-to-end.
