Why register a partnership

A partnership exists once partners sign a deed, but an unregistered firm can't file a lawsuit against third parties to enforce its contracts, and partners can't sue the firm or each other over rights under the deed. Registering with the state Registrar of Firms avoids this and is usually inexpensive.

How tax compares

A proprietor pays tax on business profit at personal slab rates — under the new regime there's no tax on income up to ₹12 lakh after the rebate. A partnership firm pays a flat 30% (plus surcharge above ₹1 crore and cess), but salaries and interest paid to working partners are deductible within limits, and partners' share of profit is exempt in their hands.

Small businesses with turnover within the limits can use presumptive taxation — declaring a fixed percentage of turnover as profit — to avoid maintaining detailed books. Proprietorships and partnership firms can both use it; LLPs cannot.

When to upgrade

Once you have meaningful assets, employees, large contracts or plans for investment, unlimited liability becomes a real risk. Converting a partnership into an LLP, or moving a proprietorship's business into a company, protects personal assets.

Frequently asked questions

Do I need to register a sole proprietorship?

There's no single registration. You establish it through registrations like GST, Udyam (MSME) or a Shops & Establishments licence, plus a current account in the business name.

Is a partnership deed mandatory?

A written deed isn't strictly required by law, but you need one to get a PAN, open a bank account and register the firm — and to avoid disputes.

Can a partnership firm be converted into an LLP?

Yes. A registered partnership can convert into an LLP by filing Form 17 with the MCA, with all partners becoming partners of the LLP.

How many partners can a firm have?

Up to 50 partners under the Companies (Miscellaneous) Rules, 2014.
