One Person Company (OPC) is a company incorporated by a single person.It is effectively a company that has only one shareholder as its member and companies are generally created when there is only one founder/promoter for the business. OPC was introduced in the Company’s Act 2013, before that a single person could not form a company therefore an individual could opt only for a sole proprietorship as you need at least a minimum of two directors and two members to establish a company.
Usually small businesses go for OPC as it is best suited for them. There are less compliances and it is very easy to incorporate.
