Sole proprietorship vs partnership vs SMC vs private limited: which to choose

For most one-person businesses starting out, a sole proprietorship is the simplest choice: you register only with FBR, your CNIC is your NTN, and there’s no fee. Choose a company (single member or private limited) when you need limited liability, plan to take investors, or expect profits high enough that the 29% company rate beats individual rates of up to 45%. A company costs from Rs 6,655 to register online with SECP and comes with more paperwork.

How do the five structures compare?

How is each one taxed?

Sole proprietors, partnerships and LLPs pay the non-salaried individual rates in tax year 2027: 0% up to Rs 6 lakh, 15% on the next slice, rising to 45% on income above Rs 56 lakh. The Finance Act 2026 left these rates unchanged. A partnership (an AOP) pays tax itself, and the partners’ shares are then exempt in their hands.

Companies pay 29% of profit, or 20% if they qualify as a small company: paid-up capital plus reserves up to Rs 5 crore, turnover up to Rs 25 crore and no more than 250 employees. When owners take profit out as dividends, they pay a further 15%.

Super tax now applies only to income above Rs 50 crore, at 8% (10% above Rs 15 crore for banks, oil and gas exploration and fertilizer). The old tiers starting at Rs 15 crore for everyone are gone.

What about liability?

• Sole proprietor: you and the business are the same person. Business debts are your debts.
• Partnership: every partner is liable, jointly and individually, for everything the firm does. An unregistered firm can’t sue to enforce its contracts.
• LLP: partners aren’t personally liable for the LLP’s debts, except for their own wrongful acts or fraud. It needs at least two partners at all times.
• SMC and private limited: separate legal entities. Owners risk only what they put into the company’s shares.

How much paperwork does each need?

• Sole proprietor: register on IRIS and file an income tax return each year. See how to register a sole proprietorship.
• Partnership: register the deed with the provincial Registrar of Firms, register the AOP with FBR at a facilitation counter, and file returns.
• Company: register on SECP’s eZfile (which also gets you an NTN), appoint an auditor within 90 days, have accounts audited (unless a private company with paid-up capital up to Rs 10 lakh, or a higher figure SECP notifies), and file annual returns with SECP after any change. See how to register a company.

Which should I choose?

• Testing an idea alone, small profits: sole proprietorship.
• Two or more people, low risk, want to keep it simple: a registered partnership, accepting unlimited liability.
• Professionals in partnership who want limited liability: LLP.
• One owner who wants limited liability or a company image: single member company.
• Co-founders or investors involved: private limited company.
