Two people, one business, and the document that quietly decides everything
The moment two or more people agree to run a business together and share its profits, Indian law treats them as a partnership — whether or not they ever put anything in writing, and whether or not they register anything. That is both the appeal and the danger of the structure. A partnership firm is the natural next step up from a sole proprietorship for people who want to build something with a co-founder without the cost and formality of a company — a family trading business, two professionals sharing a practice, a couple of friends opening a restaurant. But almost everything about how a partnership behaves — who gets paid what, who can bind the firm, what happens when someone wants out — is decided by a single document most partners treat as an afterthought: the partnership deed. Get the deed right and register the firm, and you have a clean, tax-efficient vehicle. Get them wrong and you have a dispute waiting to happen. Here is how it actually works.
How a partnership firm comes into being — the deed
A partnership in India is governed by the Indian Partnership Act, 1932, which defines it as the relation between persons who have agreed to share the profits of a business carried on by all or any of them acting for all. A firm can have a minimum of two partners and a maximum of fifty (the cap comes from Rule 10 of the Companies (Miscellaneous) Rules, 2014, framed under Section 464 of the Companies Act, 2013). The firm itself is not a separate legal person the way a company is — in law, "the firm" is really just a collective name for the partners.
What holds it together is the partnership deed — the agreement between the partners. It can technically be oral, but a written deed, executed on stamp paper, is standard and strongly advisable, because it is the firm's constitution. A good deed spells out the profit- and loss-sharing ratio, each partner's capital contribution, who the working partners are and what they are paid, the interest payable on capital, the rules for admitting or retiring a partner, how disputes are settled, and how the firm is dissolved. When partners fall out, the first document a lawyer asks for is the deed — and if it is silent or vague, the Act's default rules take over, which are rarely what anyone actually intended.
Registration is optional — but Section 69 is why you register anyway
Here is the point almost everyone gets wrong: registering a partnership firm is not compulsory. Under Section 58 of the Act you file an application with the Registrar of Firms of your state, and under Section 59 the Registrar records the firm in the Register of Firms and issues a certificate. You can do this when the firm is formed or at any time later. A perfectly valid partnership can exist and operate without ever being registered.
So why bother? Because of the disability in Section 69 — and it is a serious one. An unregistered firm cannot file a suit to enforce a contractual right against a third party, and a partner of an unregistered firm cannot sue the firm or the other partners to enforce a right arising from the partnership contract or the Act. Put plainly: if a customer refuses to pay an unregistered firm, the firm cannot go to court to recover the money; and if one partner cheats another, the wronged partner is shut out of the usual remedies. There are narrow exceptions — a suit for the dissolution of the firm or for accounts of a dissolved firm is still allowed, and Section 69 does not stop a third party from suing the firm. But the practical message is unambiguous: an unregistered firm that cannot enforce its own contracts is a firm operating with one hand tied behind its back. Register it.
How a partnership firm is taxed — where it beats a proprietorship
This is where the partnership structure earns its keep, and where it differs sharply from a proprietorship. Unlike a proprietorship — which has no separate PAN — a partnership firm is a distinct taxable entity with its own PAN, assessed separately from its partners. The firm's profits are taxed at a flat 30% (plus surcharge where applicable and a 4% health and education cess) — there are no slab rates for a firm.
The design then avoids taxing the same money twice. A partner's share of the firm's profit is exempt in the partner's own hands under Section 10(2A), because the firm has already paid tax on it. And crucially, the firm can deduct what it pays its partners in computing its own income, under Section 40(b), subject to conditions:
- Remuneration (salary, bonus, commission) is deductible only if it is paid to a working partner, is authorised by and in accordance with the partnership deed, and stays within the monetary ceiling in Section 40(b) — a formula linked to the firm's book profit, which the Finance (No. 2) Act, 2024 raised with effect from assessment year 2025-26.
- Interest on a partner's capital is deductible if authorised by the deed and does not exceed 12% per annum (simple interest).
That deductibility is a genuine planning lever: a firm can channel a large part of its profit to working partners as deductible remuneration, which is taxed in their hands (often at rates lower than 30% for smaller earners) rather than at the firm's flat 30%. The firm files its return in ITR-5.
One new compliance point every 2026 partnership must know: from 1 April 2025, Section 194T requires a firm to deduct TDS at 10% on remuneration, salary, bonus, commission or interest paid or credited to a partner, once the aggregate to that partner crosses ₹20,000 in a financial year. This is a real shift — until now, payments to partners carried no TDS at all — and it applies at the earlier of credit (including a credit to the partner's capital account) or payment.
The liability trap — unlimited, joint and several, and shared
The reason serious businesses eventually leave the partnership behind is liability. In a partnership firm, the partners have unlimited liability, and it is joint and several: every partner is personally liable for the whole of the firm's debts, not just his share, and a creditor can recover the entire amount from any one partner's personal assets. Worse, each partner is an agent of the firm — one partner's act in the ordinary course of business binds all the others. A decision you never approved, a contract signed by a co-partner, a debt you did not incur — under mutual agency, it can still land on you. This is the fundamental gap between a partnership and an LLP or a company, both of which ring-fence the owners' personal wealth from the business's debts. For a small, trust-based business between people who know each other well, unlimited joint liability may be an acceptable trade for simplicity. The day the numbers get large, or a partner you don't fully know joins, it stops being acceptable.
The other registrations a partnership firm needs
Registration with the Registrar of Firms establishes the partnership; separately, the firm takes the same operational registrations any business needs, in the firm's name and on the firm's PAN: GST registration once turnover crosses the threshold (or immediately for inter-state or e-commerce supplies), Udyam (MSME) registration for the 45-day payment protection and MSME benefits, a Shops and Establishments registration for the place of business, professional tax enrolment, and a current account in the firm's name (banks typically ask for the registered partnership deed and the firm's PAN). Sector licences — FSSAI, Import Export Code and the like — apply as they would to any other entity.
Where this sits in starting up
The partnership firm is the second rung on the business-setup ladder — the co-founder's version of the sole proprietorship. The natural question is when to climb higher, and that is exactly what the entity structure comparison answers by lining the partnership up against the LLP, the OPC and the Private Limited on liability, tax and fundraising. For most growing partnerships the next stop is the LLP — it keeps the pass-through feel of a partnership but adds limited liability and a separate legal identity. And when the business is ready to raise money or bring in outside shareholders, the path is a clean conversion of the firm into a Private Limited company.

Verification note: The requirements described here are based on the Indian Partnership Act, 1932 — under which a partnership is the relation between persons who have agreed to share the profits of a business (Section 4), registration with the Registrar of Firms is optional (Sections 58 and 59), and an unregistered firm and its partners are subject to the disability in suing to enforce contractual rights (Section 69), subject to the exceptions stated there — read with Rule 10 of the Companies (Miscellaneous) Rules, 2014 made under Section 464 of the Companies Act, 2013, which caps the number of partners at fifty. Taxation follows the Income-tax Act, 1961: a firm is a separate assessee with its own PAN taxed at a flat rate of 30% (plus applicable surcharge and a 4% health and education cess); a partner's share of firm profit is exempt under Section 10(2A); remuneration to working partners and interest on capital are deductible under Section 40(b) subject to the deed, the monetary limits linked to book profit (revised by the Finance (No. 2) Act, 2024 with effect from assessment year 2025-26) and an interest ceiling of 12% per annum; the firm files its return in ITR-5; and Section 194T, effective 1 April 2025, requires deduction of tax at source at 10% on remuneration, salary, bonus, commission or interest paid or credited to a partner where the aggregate exceeds ₹20,000 in a financial year. A partnership firm carries unlimited, joint and several liability, and each partner is an agent of the firm. Thresholds, forms, tax rates and monetary limits are periodically revised by the relevant authorities; confirm the current requirements for your firm and state with your CA.
