One Person Company Registration — documents, process and timeline

A One Person Company is the only Indian corporate form with a single shareholder. It was introduced by the Companies Act 2013 to give a sole founder what a proprietorship cannot: a separate legal person, so that a business debt stops at the company and does not reach the founder's house, savings or other assets.

It needs one shareholder, one director — which can be the same person — and one nominee. The nominee is the distinguishing feature: a natural person named in the memorandum who becomes the shareholder if the sole member dies or becomes incapable of contracting. Their written consent in Form INC-3 is filed at incorporation, and the arrangement is what allows a single-member company to have perpetual succession at all.

Only a natural person who is an Indian citizen can incorporate one, and one person can hold only one OPC and be the nominee of only one other. Since the 2021 amendment, an NRI may incorporate an OPC and the residency requirement was reduced from 182 days to 120.

The compliance is genuinely lighter than a private limited company's in specific respects. No annual general meeting is required, so AOC-4 is due within 180 days of the financial year end rather than thirty days after a meeting. The annual return is the abridged MGT-7A. Where there is only one director, a resolution entered in the minutes book and signed serves as a board meeting. Cash flow statements are not required.

What is not lighter is the audit. A statutory audit applies from the first financial year regardless of turnover, exactly as it does for any other company, which is the main running cost and the main difference from an LLP below the audit threshold.

Conversion into a private limited company becomes compulsory once paid-up capital exceeds ₹50 lakh or average annual turnover over three consecutive years exceeds ₹2 crore. Notice must be given in Form INC-5 within sixty days of crossing, and the conversion completed within six months. Voluntary conversion is available at any time since the two-year waiting period was removed in 2021.

The structural limitation worth understanding before choosing the form is that an OPC cannot raise equity from an investor without ceasing to be an OPC — the moment a second shareholder comes in, it must convert. It also cannot carry on non-banking financial investment activity. For a founder who genuinely intends to remain sole owner, it is the right structure; for one who expects to bring in a co-founder or an investor within a year or two, incorporating a private limited company at the outset avoids a conversion at an inconvenient moment.

On tax there is no OPC-specific rate, and this surprises people who assume the lighter compliance implies lighter taxation. An OPC is a domestic company and is taxed as one: 25% where turnover is within the prescribed limit, or 22% plus surcharge and cess if it opts into section 115BAA and gives up most incentive deductions. Against a proprietorship taxed at slab rates with a basic exemption, the OPC is worse at low income and better once profits are substantial and being retained rather than drawn. The crossover depends on how much the founder needs to take out personally, because money drawn from the company as salary is taxed in their hands and money drawn as dividend is taxed again.

The nominee arrangement deserves more thought than it usually gets. The nominee does not own anything while the member is alive and has no say in how the company is run — they simply step into the shareholding on death or incapacity. But because they become the sole owner of the entire business at that moment, the choice interacts directly with the founder's personal succession planning. Where a founder has a will dealing with their estate, the OPC nomination can cut across it, since the shares pass by the nomination rather than under the will. That is worth reconciling deliberately rather than discovering later.

Key features

One shareholder, one director, one nomineeThe shareholder and director can be the same person. The nominee is compulsory and their consent is filed at incorporation.
Limited liabilityThe founder risks the capital subscribed, not personal assets — the central difference from a proprietorship.
No annual general meetingAOC-4 is due within 180 days of the year end rather than thirty days after a meeting, and MGT-7A replaces the full annual return.
Audit from year oneCompulsory regardless of turnover, the same as any company. This is the main running cost.
One OPC per personA person may incorporate only one OPC and be the nominee of only one other.
Conversion is compulsory above the thresholds₹50 lakh paid-up capital or ₹2 crore average turnover over three years triggers mandatory conversion.

Who needs it

Sole founders wanting liability protectionAnyone trading alone with real exposure — inventory, credit, employees or contracts — is safer inside a limited liability structure.
Consultants and professionals billing companiesCorporate clients often prefer an incorporated supplier with a CIN and filed accounts to an individual.
Businesses that will stay single-ownerThe form works well where there is no intention to bring in a co-founder or investor.
Not for anyone raising equityA second shareholder forces conversion. If a raise is likely, incorporate a private limited company at the outset.
Not for NBFC activityAn OPC cannot carry on non-banking financial investment business, including investing in securities of other bodies corporate.

Which one applies to you

OPC limited by sharesThe ordinary case. Liability is limited to any unpaid amount on the shares held.
OPC limited by guaranteePermitted by the Act but rarely used, since the guarantee structure suits membership bodies rather than a single owner.
Small company OPCMost OPCs also meet the small company thresholds, which brings the lighter MGT-7A and reduced board meeting requirements.

Why it is worth doing

Personal assets are protectedThe company contracts and owes in its own name. A creditor cannot reach the founder except on a personal guarantee.
A separate legal identityThe company owns its assets, holds its own bank account and can hold intellectual property in its own name.
Perpetual succession through the nomineeThe business continues if the founder dies, rather than forming part of a personal estate to be administered.
Corporate credibilityA CIN, filed accounts and a company bank account carry weight with clients, lenders and landlords that a proprietorship does not.
Lighter than a private company in real waysNo AGM, an abridged return, no cash flow statement, and a single-director resolution serves as a board meeting.

OPC or sole proprietorship?

	OPC	Proprietorship
Legal identity	Separate from the owner	Same as the owner
Liability	Limited to capital subscribed	Unlimited — personal assets exposed
Audit	Compulsory from year one	Only above ₹1 crore turnover
Annual filings	AOC-4 and MGT-7A with the MCA	None with the MCA
Survives the owner	Yes, through the nominee	No — it forms part of the estate
Running cost	Higher	Minimal

What affects the timeline

Name availabilityA refused name costs three to five working days and a fresh fee. The "(OPC) Private Limited" suffix is compulsory and often forgotten.
Nominee availabilityThe nominee must sign INC-3 and provide identity documents. A nominee who is travelling holds the whole file.
Address proof currencyThe utility bill must be within two months and match the no-objection letter, or the filing comes back for resubmission.
Registrar workloadProcessing varies between ROC offices and slows markedly in March.

What happens afterwards

Auditor within thirty daysThe board appoints the first auditor and files ADT-1. Without one the accounts cannot be audited and AOC-4 cannot be filed.
INC-20A before tradingThe declaration of commencement of business is due within 180 days and must precede any borrowing or operations.
AOC-4 within 180 days of the year endNo AGM is required, so the deadline runs from the financial year end rather than from a meeting.
MGT-7A annual returnThe abridged form, plus DIR-3 KYC for the director by 30 September.
Watch the conversion thresholdsCrossing ₹50 lakh capital or ₹2 crore average turnover requires notice in INC-5 within sixty days.
Keep the nominee currentA nominee who withdraws must be replaced within fifteen days, with INC-4 filed. An OPC without a valid nominee is non-compliant.

What usually goes wrong

Not appointing a nominee properlyINC-3 consent is compulsory at incorporation, and a nominee who later withdraws must be replaced within fifteen days.
Choosing an OPC then raising moneyA second shareholder forces conversion. Founders expecting a raise should incorporate a private limited company from the start.
Missing the conversion thresholdsINC-5 is due within sixty days of crossing ₹50 lakh capital or ₹2 crore average turnover. Continuing as an OPC beyond that is a default.
Assuming no AGM means no filingsAOC-4 and MGT-7A are still due, on a 180-day clock. The exemption is from the meeting, not from the return.
Forgetting the name suffixThe name must end "(OPC) Private Limited". Applications without it are refused at name reservation.
Holding more than one OPCOne person, one OPC, and nominee of only one other. A second incorporation will be refused.

Questions

Can an NRI register an OPC?

Yes, since the 2021 amendment. An NRI may now incorporate an OPC, and the residency requirement was reduced from 182 days to 120 days in the preceding financial year. Before 2021 only a resident Indian citizen could.

What happens when my OPC grows?

Conversion to a private limited company becomes mandatory once paid-up capital exceeds ₹50 lakh or average annual turnover across three consecutive years exceeds ₹2 crore. Notice in Form INC-5 is due within sixty days of crossing, and the conversion must be completed within six months.

Who can be the nominee of an OPC?

Any natural person who is an Indian citizen and who is not already the nominee or member of another OPC. Their written consent in Form INC-3 is filed at incorporation, and they become the shareholder if the sole member dies or becomes incapable of contracting.

Does an OPC need to hold an AGM?

No. Section 96 exempts an OPC from holding an annual general meeting. The accounts are signed by the sole director and filed in AOC-4 within 180 days of the financial year end, which is why the deadline runs from the year rather than from a meeting.

Does an OPC need a statutory audit?

Yes, from the first financial year and regardless of turnover, exactly as any other company does. This is the main running cost and the principal difference from an LLP, which is only audited above ₹40 lakh turnover.

Can an OPC have more than one director?

Yes — up to fifteen. What it cannot have is more than one shareholder. The single-member requirement is about ownership, not about the board.

OPC or private limited company?

An OPC if you genuinely intend to remain the sole owner. A private limited company if there is any realistic prospect of a co-founder or investor within a couple of years, because a second shareholder forces a conversion that takes four to eight weeks and tends to arrive at an inconvenient moment.

Can an OPC do any business?

Almost. It cannot carry on non-banking financial investment activity, including investing in the securities of other bodies corporate. Everything else is open to it on the same terms as any private company.
