Companies Act introduced the concept of One Person Company (OPC) in India was introduced in 2013 to support proprietors who were inclined to start an enterprise on their own with limited liability. The most basic difference between a sole proprietor and a One Person Company is that in case of a One Person Company (OPC), owner liability in worst case scenario is limited to only the business assets however in case of a proprietorship, there’s unlimited liability. OPC is a separate legal entity, and offers continuity of business and is easy to incorporate the only catch being your turnover not exceeding 2 crores annually.
