What Is an AOP / Partnership Firm?
An Association of Persons (AOP) — which includes registered and unregistered partnership firms — is a distinct taxpayer category under Pakistani tax law, separate from individuals and companies. Two or more people carrying on business together for profit are typically taxed as an AOP.
How Partnership Firms Are Taxed
The AOP itself is the taxable entity and pays tax on its total income at progressive AOP slab rates. Once tax is paid at the firm level, each partner's share of the after-tax profit distributed from the AOP is generally exempt from further tax in their personal return.
| Taxable Income Slab | AOP Tax Treatment |
|---|---|
| Up to exemption threshold | 0% |
| Lower-middle slabs | Progressive rates starting around 5-10% |
| Higher slabs | Progressive rates up to 35%+ on top bracket |
Note: Actual AOP slab rates and thresholds are revised periodically by the Finance Act. Confirm current rates with a tax advisor before filing.
Registering Your Partnership Firm with FBR
- Register the partnership deed (recommended, though not strictly mandatory for tax purposes)
- Obtain an NTN for the AOP via FBR's IRIS portal
- Register for sales tax (STRN) if engaged in taxable supplies
- Open a business bank account in the firm's name
- Maintain books of accounts as required for the firm's income level
Annual Filing Requirements
The AOP must file an annual income tax return declaring total income, allowable expenses, and tax computed at AOP rates. Partners must also file individual returns disclosing their share of AOP income — even though it is typically exempt from re-taxation — along with any other personal income sources.

- Charge 17% standard sales tax on goods (or applicable reduced rate)
- Issue FBR-compliant invoices with your STRN
- File monthly returns and pay net tax (output minus input)
- Maintain records for 5 years minimum
Minimum Tax — Section 113
If a company's normal tax liability is less than 1.25% of gross turnover, it must pay minimum tax. This applies even if the company shows a loss. For certain sectors (distributors, dealers), minimum tax rates differ.
Super Tax — Large Companies
Companies with income exceeding Rs.150 million pay Super Tax at 1-10% depending on income bracket and sector. Banking companies face a 10% super tax rate. This is on top of the normal 29% corporate tax rate.

Frequently Asked Questions — Business Tax Pakistan 2026
What is the corporate tax rate in Pakistan 2026?
The standard corporate tax rate in Pakistan for 2026-27 is 29% for private companies. Banks pay a higher rate of 39% (corporate tax 29% plus super tax 10%). Listed companies benefit from a 2% tax credit if they increase their tax paid from the previous year by 20%. Small companies (defined under the Companies Act) pay a reduced rate of 20% if meeting eligibility criteria.
When must a business register for sales tax (STRN) in Pakistan?
A business must register for sales tax registration (STRN) Number (STRN) if its annual taxable supplies of goods or services exceed Rs.10 million. Additionally, FBR can compulsorily register any person or business they believe should be registered. Service providers in Punjab, Sindh, Khyber Pakhtunkhwa, and Balochistan must register with their respective provincial revenue authorities (PRA, SRB, KPRA, BRA) for service tax, with registration thresholds varying by province.
What is advance tax and how is it calculated for businesses?
Advance tax is paid quarterly by companies and businesses with annual tax liability above Rs.100,000. Each quarterly installment is 25% of the last assessed tax liability or estimated current year tax, whichever is higher. Installments are due on September 25, December 25, March 25, and June 15. Under-payment of advance tax results in 12% annual markup on the shortfall.
What is the difference between a sole proprietorship and an AOP for tax purposes?
A sole proprietorship has no separate legal entity — all income is declared in the owner's personal income tax return. An Association of Persons (AOP) is a partnership or joint venture that files its own tax return at AOP tax rates (similar to individual slab rates). The key difference is that AOP income is taxed at the AOP level first, and then individual partners' shares are also included in their personal returns — creating a potential double taxation issue that requires careful planning.
What records must a business maintain under Pakistan tax law?
Under Section 174 of the Income Tax Ordinance, businesses must maintain proper accounts and records for at least 5 years from the end of the income tax return filing. Required records include: sales and purchase invoices, cash receipts and payment vouchers, bank statements, payroll records and salary slips, stock registers, fixed asset schedules, and loan/liability documentation. For sales tax registered businesses, FBR requires additional records including output/input tax registers and STRN-compliant invoices.
