This guide is general information. If you would rather a chartered accountant handled it, see Private Limited Company Registration or LLP Registration.
The structure you pick affects your liability, compliance, tax and ability to raise money. Here is a practical comparison.
| Proprietorship | OPC | LLP | Private Limited | |
|---|---|---|---|---|
| Separate legal entity | No | Yes | Yes | Yes |
| Owners | 1 | 1 (plus nominee) | 2 or more partners | 2 or more shareholders |
| Liability | Unlimited | Limited | Limited | Limited |
| Raising equity | Not possible | Limited | Limited, no shares | Easiest |
| Compliance | Lowest | Moderate | Moderate | Highest |
| Annual audit | Only if tax audit applies | Yes | Above turnover or contribution limits | Yes |
When each one fits
- Proprietorship: small, low-risk businesses just starting, with the lowest compliance
- OPC: a single founder who wants limited liability
- LLP: professional firms and closely held businesses that want flexibility and lighter compliance
- Private limited company: businesses planning to raise investment, issue ESOPs or scale
Tax
Proprietors are taxed at individual slab rates. Companies pay corporate tax at rates that depend on the regime chosen. LLPs are taxed as firms. The best choice depends on your profit level and plans, so compare before deciding.
Switching later
You can usually convert a proprietorship or partnership into an LLP or company later, and an OPC into a private company, but conversions have costs and conditions. If investment is likely in the next two years, starting with a private limited company often saves effort.
Questions to ask yourself before choosing
- Will you raise equity money from investors in the next two years?
- Do you need limited liability because of the risks of the business?
- Is there more than one owner, and how will profit and control be shared?
- How much compliance cost and paperwork can you handle?
- Do you plan to sell shares or give ESOPs to employees?
- Do you want to keep the structure simple and convert later?
Common scenarios
- A single consultant who wants to start now: a proprietorship, with GST and other registrations as needed, is the lowest-effort start.
- Two friends opening a professional practice: an LLP gives limited liability with flexible profit sharing.
- A technology founder planning to raise seed money: a private limited company is the usual choice because investors expect shares and a standard structure.
- A single founder who wants limited liability but is not ready for partners: an OPC, with the option of converting later.
Tax in one paragraph
Proprietors pay tax at individual slab rates on business profit. Partnership firms and LLPs pay tax at a flat rate on profit, and partners' share of profit is exempt in their hands. Companies pay corporate tax at the applicable rate, and shareholders pay tax on dividends they receive. Which is cheaper depends on how much profit you want to take out, so compare using your projected numbers instead of relying on general claims.
Cost and effort of compliance, side by side
| Structure | Typical yearly compliance |
|---|---|
| Proprietorship | Income tax return, GST if applicable, TDS if applicable |
| OPC | Statutory audit, AOC-4, MGT-7A, income tax return, GST and TDS if applicable, director KYC |
| LLP | Form 11, Form 8, income tax return, audit above thresholds, GST and TDS if applicable |
| Private limited | Statutory audit, board meetings, AGM, AOC-4, MGT-7, income tax return, GST and TDS if applicable, director KYC |
Other factors that matter in practice
- Bank and vendor perception: larger customers and lenders often prefer dealing with a company or LLP.
- Licences and tenders: some tenders and licences have conditions about the type of entity.
- Ease of exit: closing a proprietorship is easy; closing a company or LLP follows a formal procedure.
- Foreign investment: sectors and routes under FEMA may favour companies.
- Succession: a company continues after the death of an owner, and an OPC has a nominee.
If in doubt, start with the structure that matches the next two years of plans, and revisit as the business grows.
A quick decision guide
If you want the lowest cost and effort and your risk is small, start as a proprietor. If you are alone but want limited liability, choose an OPC. If you are two or more professionals who value flexibility, choose an LLP. If you plan to raise equity or give ESOPs, choose a private limited company. Write down your plans for the next two years, check each point against the table above, and speak to a CA before filing, because moving from one structure to another later costs time and money.
Official sources: the Companies Act, 2013 and the LLP Act, 2008 on the website of the Ministry of Corporate Affairs describe each structure in detail.
Frequently asked questions
Can a proprietorship take investment?
Not by selling equity, because it has no shares. It can borrow money. Investors who want equity generally ask the business to become a company.
Is an LLP better than a private limited company?
Neither is better in general. An LLP has lighter compliance and is flexible for professionals. A private limited company suits businesses planning to raise equity.
Can I convert later?
Yes. Proprietorships, partnerships, LLPs and OPCs can be converted, with conditions and costs. Plan for it if investment is likely.
Which has the lowest compliance?
A proprietorship, followed by a partnership, then an LLP, an OPC and a private limited company.
