Business Tax in Pakistan 2026: Complete Guide & Rates

Quick Answer
Business tax in Pakistan is charged on a company, AOP, or sole proprietor’s net taxable profit, not gross turnover. Companies pay corporate tax under the Income Tax Ordinance, 2001 — 29% for standard companies and lower rates for small companies and SMEs — while sole proprietors and Associations of Persons (AOPs) are taxed on a progressive slab scale. A separate 1–1.5% minimum turnover tax, sales tax, and withholding tax obligations may also apply, and returns are filed annually through FBR’s IRIS portal.
