According to the Finance Act 2025 and official FBR guidelines, the income tax slabs for the fiscal year 2025-26 have been revised to provide relief to low and middle-income salaried individuals in Pakistan. Under the current regime, any annual income up to Rs. 600,000 (Rs. 50,000 monthly) remains completely tax-exempt. For incomes exceeding this limit, progressive tax rates are applied. Specifically, those earning between Rs. 600,000 and Rs. 1,200,000 now enjoy a significantly reduced rate of 1% (down from 5% in 2024-25), providing substantial relief of up to Rs. 24,000 annually.
