If you run a small business alone or with one or two others, the real choice is usually between three forms: a sole proprietorship, a partnership firm and a limited liability partnership (LLP). The first two are cheap and quick to start but leave your personal savings exposed to the business’s debts. The LLP costs more to set up and run, and in exchange it ring-fences what you own outside the business.
Everything else, from tax to paperwork, follows from that trade-off. The table below gives the overview; the sections after it explain where the differences actually bite. If you have already decided on an LLP, our LLP registration service handles the MCA steps for you.
The three side by side
| Sole proprietorship | Partnership firm | LLP | |
|---|---|---|---|
| Owners | One person | Two or more partners | Two or more partners, two of them designated partners |
| Separate legal person? | No, the owner and the business are the same | No, the firm is the partners collectively | Yes, a body corporate |
| Your liability | Unlimited | Unlimited, and each partner for the whole firm’s debts | Limited to your agreed contribution, except for your own wrongful acts |
| Governing law | No specific law | Indian Partnership Act, 1932 | LLP Act, 2008 |
| How it is formed | No formation step; identity comes from tax and trade registrations | A partnership deed; registration with the state Registrar of Firms | Incorporation with the MCA, then an LLP agreement |
| Yearly filings with a registrar | None | None, apart from reporting changes | Form 11 and Form 8 to the MCA |
| Audit | Only if tax law requires one | Only if tax law requires one | Also under the LLP rules above ₹40 lakh turnover or ₹25 lakh contribution |
| Survives an owner leaving? | No | Depends on the deed | Yes, perpetual succession |
Liability: what is actually at risk
In a sole proprietorship, the business’s debts are your debts. A supplier who is not paid, a landlord with a claim, a customer who wins a damages case: all of them can pursue your house, savings and car.
A partnership firm is the same, but wider. Each partner is liable for the firm’s debts together with the others, and a creditor can recover the full amount from any one of them. You can end up paying for a decision your partner took alone, as long as it was within the firm’s business.
An LLP breaks that link. The LLP owns its assets and owes its debts. A partner’s exposure is generally the contribution they agreed to bring in, though a partner who acts fraudulently or wrongfully stays personally liable for that act. For a business that signs contracts, takes credit or carries any real risk of claims, this is the main reason to choose an LLP over the other two.
Setting up
A sole proprietorship has no registration of its own. You start trading in your own name or a trade name, and the business’s identity is built from other registrations: your PAN, a GST registration if your turnover or type of supply requires it, a Udyam registration (free on the government portal), and a shop and establishment registration under your state’s law. Banks usually want two such documents to open a current account in the trade name.
A partnership firm starts with a partnership deed signed by the partners and stamped under your state’s stamp law. Registration with the state Registrar of Firms is optional under the central Act, but an unregistered firm cannot sue third parties to enforce its contracts, and partners cannot sue the firm or each other on the deed. Some states have tightened the rule: in Maharashtra, for example, the state amendment requires the registration statement to be filed within one year of the firm’s constitution.
An LLP is incorporated online through the MCA: a name reserved through RUN-LLP, incorporation through FiLLiP, then the LLP agreement filed within 30 days. Each designated partner needs a digital signature and an identification number, and at least one of them must have stayed in India for 120 days or more in the financial year.
Tax
The Income-tax Act, 2025 has applied from 1 April 2026; check current rates with a chartered accountant.
- Sole proprietorship: business profit is part of your personal income and taxed at the slab rates that apply to you. There is no separate return for the business.
- Partnership firm and LLP: both are taxed as firms, on their own profit, at the rate that applies to firms. A partner’s share of that profit is not taxed again in the partner’s hands. Salary and interest paid to working partners can be deducted by the firm within limits, if the deed or agreement provides for them, and are taxable for the partner.
At low profit, a proprietor’s slab rates can mean less tax than a firm’s flat rate. As profit grows, the comparison can flip. This is worth modelling with real numbers before choosing.
Yearly running cost
A sole proprietorship and a partnership firm have no yearly filings with any registrar; their compliance is tax returns, GST returns if registered, and state labour registrations. A registered firm must report changes such as a new partner or a new address to the Registrar of Firms.
An LLP adds two MCA filings every year, Form 11 by 30 May and Form 8 by 30 October, and each designated partner’s KYC when it is due. Both MCA forms are due even in a year with no business, and late filing brings additional fees for every day of delay. The audit requirement under the LLP rules applies only above the thresholds in the table. In practice, a small LLP costs more to run than a firm but much less than a private limited company.
Changing structure later
Starting simple is fine if you know the exit route.
- Partnership firm to LLP: the LLP Act has a direct conversion route for firms, in which the firm’s assets, liabilities and contracts move to the LLP.
- Partnership firm to company: the Companies Act allows a firm to register as a company, subject to conditions.
- Sole proprietorship to LLP or company: there is no direct statutory conversion. You form the new entity and transfer the business into it. The tax and GST effects need planning.
So which one?
- A one-person business with modest risk and no plans to scale soon can start as a proprietorship, but should move on once contracts, credit or staff grow.
- Two or more people who need to start immediately and trust each other completely can use a partnership, provided they write a careful deed and register the firm.
- Two or more people with real business risk, or who want the business to outlast any one partner, should look hard at an LLP.
