Quick answerThere is no direct statutory conversion of a sole proprietorship into a One Person Company, because a proprietorship is not a separate legal entity. Instead, the proprietor incorporates an OPC under the Companies Act, 2013 as its sole member, naming a nominee, and then transfers the business to the OPC as a going concern under a business transfer agreement. The OPC takes a new PAN and GST registration, the unused input tax credit is transferred, and contracts, licences and accounts are moved across.

Why proprietors move to an OPC
In a proprietorship, the owner and the business are the same person in law. Every business debt is a personal debt, and the business ends with the owner. An OPC changes that:
- Limited liability: the company is liable for its debts; the member's risk is limited to the share capital, except where he gives personal guarantees.
- Continuity: the nominee named at incorporation becomes the member if the sole member dies or becomes incapable, so the company continues.
- Credibility: large customers, government buyers and lenders often prefer dealing with a company registered with the MCA.
- Growth path: when you bring in a partner or investor, the OPC can be converted into a private limited company.
The cost is compliance: the OPC has an annual audit, ROC filings and a separate income tax return, and money in the company belongs to the company, not to the owner. If you expect to take in a co-founder soon, it may be simpler to form a private limited company directly.
Who can form the OPC
Under Rule 3 of the Companies (Incorporation) Rules, 2014, only a natural person who is an Indian citizen can be the member of an OPC, and the same applies to the nominee. Since the 2021 amendment, the member need not be resident in India, and the old limits on paid-up capital and turnover that forced conversion have been removed. A person can be a member of only one OPC at a time. An OPC cannot carry on non-banking financial investment activities and cannot be incorporated as a Section 8 company. The proprietor is usually the sole member and director; a family member is typically the nominee, who gives consent in Form INC-3.
How the conversion works: two stages
Stage 1: incorporate the OPC. The OPC is incorporated through SPICe+ with its MOA and AOA, like any company. The name can carry your existing trade name if it is available on the MCA register and does not conflict with a registered trademark, and ends with "(OPC) Private Limited".
Stage 2: transfer the business. The proprietor and the OPC sign a business transfer agreement (BTA) under which the business is sold to the OPC as a going concern, with a list of assets and liabilities transferred and the consideration. The consideration is usually shares of the OPC allotted to the proprietor, sometimes with a balance recorded as a loan. The BTA fixes the effective date, after which all sales are billed by the OPC.
The BTA is stamped under the state stamp law. Movable assets pass by delivery under the agreement; immovable property needs a separate registered conveyance with stamp duty, so many proprietors keep property in their own name and lease it to the OPC instead.
GST, licences and registrations
| Item | What happens |
|---|
| PAN and TAN | The OPC receives its own PAN and TAN at incorporation; the proprietor's PAN stays with him as an individual |
| GST | The OPC takes a new GSTIN from the transfer date. Unused input tax credit is moved to it in Form ITC-02 under Section 18(3) of the CGST Act, and the proprietor's registration is cancelled citing transfer of business |
| Udyam | The OPC obtains its own Udyam registration |
| FSSAI, drug, trade and other licences | Generally issued to the person carrying on business; the OPC applies afresh or for modification as each law permits |
| Trademarks | Assigned to the OPC and recorded with the Trade Marks Registry |
| PF and ESI | Employee registrations moved to the OPC's code with continuity of service |
| Bank accounts and contracts | New current account; key contracts novated with the other party's consent |
Transfer of a business as a going concern is generally treated as exempt under the GST rate notifications, but this depends on the whole business moving across, so the BTA must be drafted with that in mind.
Income tax points to plan
The transfer of a proprietorship to a company is a transfer of capital assets and can give rise to capital gains. The Income-tax Act, 1961 exempted it in old Section 47(xiv) where all the assets and liabilities passed to the company, the proprietor held at least 50% of the voting power for five years, and he received no consideration other than shares. The Income-tax Act, 2025 applies from 1 April 2026 under new numbering, so the current provision and its conditions must be confirmed before the transfer date. Unabsorbed losses and depreciation of the proprietorship, and the treatment of stock and debtors, also need attention. We plan this with your chartered accountant before the BTA is signed.
Customers, employees and lenders
The legal transfer is only half the work. Customers need written notice of the effective date, the OPC's new GSTIN and bank details, so that invoices and payments move across together. Running contracts, rental agreements and distributor arrangements usually need the other party's consent to be novated in the OPC's name. Employees move with written consent and continuity of service, so that gratuity and leave are not lost, and the transfer is reflected in their PF and ESI records. Business loans in the proprietor's name stay his personal liability unless the lender agrees to transfer them to the OPC, which most banks treat as a fresh credit decision.
Mistakes to avoid
- Continuing to bill in the proprietorship after the transfer date, which splits turnover and confuses GST returns.
- Cancelling the old GSTIN before ITC-02 is accepted, losing the input tax credit.
- Not informing customers and suppliers in writing, so payments keep coming to the old account.
- Leaving the trademark in the proprietor's personal name while the OPC uses it, without a licence or assignment.
- Transferring only some assets, which can cost the tax exemption.
Costs and timeline
The costs are the OPC incorporation (stamp duty on the MOA and AOA, which depends on the state, and the DSC), stamp duty on the business transfer agreement, the new registrations, and professional fees. We quote the full package in writing. Incorporation usually takes one to three weeks; the transfer of GST, licences and contracts generally completes within the following few weeks.

Can a proprietorship be directly converted into an OPC?
No. The law has no direct conversion route. An OPC is incorporated and the proprietorship business is transferred to it under a business transfer agreement.
Will my GST number stay the same?
No. The OPC needs its own GSTIN. Unused input tax credit can be moved to it in Form ITC-02 after the business is transferred.
Can I keep my business name?
Usually yes, if the name is available on the MCA register and does not conflict with someone else's trademark. It will end with (OPC) Private Limited.
Who can be the nominee of an OPC?
An Indian citizen who is a natural person, usually a family member, who consents in Form INC-3.
Is capital gains tax payable on transferring a proprietorship to an OPC?
It can be, unless the transfer meets the conditions for exemption. Those conditions must be checked under the Income-tax Act, 2025 before the transfer.

Yes. Since 2021 an OPC can convert voluntarily at any time by adding members and directors and filing INC-6.
