Most Pakistani businesses start as a sole proprietorship because it requires almost nothing, and many stay that way long past the point where it makes sense. The choice between the three common structures turns on three things: liability, tax, and who you intend to do business with.
Sole proprietorship
There is no separate legal entity. The business is you. Registration consists of obtaining an NTN from FBR in your own name with a business name, and a letterhead, a bank account and, where applicable, a local trade licence.
Liability is unlimited. A business debt is your personal debt. A supplier with an unpaid invoice, a bank with a defaulted loan, or a claimant with a damages decree can execute against your house, your car and your personal accounts. This is the whole of the case against staying a proprietorship once the business carries real obligations.
Tax is at individual slab rates on business income, which is progressive - an advantage at low income and a disadvantage at high income.
It suits a genuinely small operation: a single consultant, a shop, a service business with no borrowing and no meaningful contractual exposure.
Association of Persons (AOP) / partnership
Two or more persons carrying on business together. A partnership deed is executed, stamped, and registered with the Registrar of Firms under the Partnership Act, 1932. The AOP obtains its own NTN.
Liability remains unlimited, and it is joint and several - meaning each partner can be pursued for the whole of the firm's debt, not merely their share. A partner is also bound by the acts of the other partners done in the course of the business. This is the point that ruins partnerships: you are liable for your partner's commitments whether or not you knew of them.
Tax is charged on the AOP at AOP rates, and the share received by a partner is then generally not taxed again in the partner's hands, though it is included for rate purposes.
Registration is not compulsory, but an unregistered firm cannot sue to enforce a contract, which in practice makes registration compulsory.
Private limited company
Incorporated with the SECP under the Companies Act, 2017. The company is a separate legal person: it owns its own assets, incurs its own debts, sues and is sued in its own name.
Liability is limited to the unpaid amount on the shares. If the company fails, the shareholders lose what they put in and, ordinarily, no more. That protection is the entire reason the structure exists.
The protection is not absolute. It falls away where directors have given personal guarantees - which banks routinely require, so the limited liability is often surrendered at the first loan - and where there has been fraud or trading in disregard of the company's solvency.
Tax is at the corporate rate on profits, and distributions to shareholders attract dividend tax. At higher profit levels the combined burden needs modelling against the individual slab rates before assuming the company is cheaper.
The compliance a company actually carries
This is what people underestimate. A private limited company must:
- Hold an annual general meeting and maintain statutory registers
- File an annual return with SECP, and file financial statements (small companies have a lighter regime)
- Notify SECP of changes in directors, registered office and share capital, within the prescribed periods
- Maintain proper books of account
- File corporate tax returns and withholding statements
Late filings attract penalties, and the penalties accumulate quietly until they are discovered at the moment you need a clean record for a bank or an investor.
Single Member Company
The Companies Act allows a single member company - a private limited company with one shareholder. It gives a solo founder the liability protection of a company without needing a nominal second shareholder. A nominee must be appointed to take over on the member's death.
For a consultant or freelancer who has outgrown proprietorship, this is usually the right answer.
Choosing
Move to a company when any of these become true:
- You are taking on contractual obligations you could not personally satisfy if they went wrong
- You are hiring employees in numbers
- You need to take investment - equity cannot be issued in a proprietorship
- Your customers are corporate or public sector, who often will not contract with individuals
- You are trading internationally and need the credibility of an incorporated counterparty
Stay a proprietorship while the business is genuinely small, unlevered and low-risk, and the compliance cost of a company would exceed the protection it buys.
Converting later
A proprietorship or AOP can be converted into a company, with the assets and business transferred to the new entity. It is a taxable event that needs planning, and contracts, licences, bank mandates and registrations must be novated or reissued. Converting is not difficult but it is not free, which is an argument for choosing correctly at the point the business starts carrying real risk.
