Proprietorship: simple, unlimited liability

OPC: protected, more compliance
Limited liability and credibility, with audit and ROC filings like a company.
Liability, tax and credibility compared
The real differences are liability, taxation and how the outside world sees you. A proprietorship is not a separate legal person, so the owner’s personal assets stand behind every business debt; an OPC is a separate company, so liability is limited to what’s invested (absent personal guarantees). On tax, a proprietorship’s profit is the owner’s personal income at slab rates, with the presumptive 44AD/44ADA options available; an OPC is taxed as a company — a flat corporate rate, with access to the concessional 22% or 15% regimes — and distributing its profits to the owner as dividend is taxable in the owner’s hands, so the combined tax can be higher on profits taken out. Against that, the OPC offers credibility with banks, customers and vendors, perpetual succession through the nominee, and a cleaner path to later convert into a Private Limited if you raise capital. Compliance is heavier for the OPC (audit, ROC filings) than for a proprietor. The choice turns on whether liability protection and a corporate identity justify the extra compliance and the dividend-tax friction — often yes for a growing solo business, often no for a very small one.
