OPC registration refers to the process of legally incorporating a One Person Company (OPC) in India under the Companies Act, 2013. It is designed for solo entrepreneurs who wish to enjoy the benefits of limited liability and a separate legal entity while maintaining full control over their business. To apply for OPC registration, an individual must be an Indian citizen and resident, meaning they have stayed in India for at least 182 days in the preceding financial year. Additionally, the individual cannot be a member or nominee of more than one OPC simultaneously. A nominee must also be appointed during the registration process to take over in case of the owner's incapacity or death. OPC registration is ideal for small businesses, startups, or professionals looking for legal recognition and liability protection while operating independently.
