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 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 tax year. 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.
