Key features of a proprietary concern include:

1) Single Ownership: The business is owned by one person, who is responsible for all decisions, profits, and liabilities.

2) Unlimited Liability: The proprietor’s personal assets are at risk in case of business debts or legal issues.

3) Full Control: The owner has complete control over the business, including operations, financial decisions, and day-to-day management.

4) Taxation: Income generated by the business is considered the personal income of the owner and is taxed accordingly.

5) Simple Registration: It is easy to set up, with minimal regulatory requirements compared to other business structures.

A proprietary concern is suitable for small businesses and individuals who want to operate without the complexity of formal legal structures.
