To choose the right business structure, the first aspect is to decide if there is any business partner or not. Those who wish to be sole owners opt for Sole Proprietorship and OPC whereas other structures can be established with partners.
Next thing is to decide about the capital requirement. For businesses with a large capital requirement, corporate structures are beneficial. Apart from all other pre-registration aspects, one must not forget to consider the post-registration aspects, tax liabilities, and compliance matters.
