Converting a proprietorship into a One Person Company (OPC) allows a business owner to enjoy the benefits of a separate legal entity while retaining sole ownership. The OPC structure provides limited liability protection, meaning the owner’s personal assets are protected from business liabilities. The process involves obtaining a Digital Signature Certificate (DSC) and Director Identification Number (DIN) for the proposed director of the OPC. The business owner then applies for incorporation using SPICe (INC-32), along with a Memorandum of Association (MOA) and Articles of Association (AOA) tailored for a single-member company. Once the ROC approves the application and issues the certificate of incorporation, the proprietorship’s business operations, assets, and liabilities can be transferred to the OPC. Professional guidance is recommended to ensure accurate documentation, compliance with statutory formalities, and smooth transfer of business operations. Converting to an OPC enhances credibility with banks, investors, and clients, provides perpetual succession, and facilitates growth opportunities while maintaining control with a single owner. Proper conversion ensures legal recognition and structured governance under the OPC framework.
