Pakistan taxes salaried income on six slabs, and salaried people get their own schedule — the rates below are lower than those charged to non-salaried individuals and associations of persons on the same income. The first PKR 600,000 is free of tax, and the top rate of 35% starts at PKR 4,100,000.
The slabs are not independent bands. Each row states a fixed amount that already contains the tax on everything below it, plus a marginal rate on the excess. Adding up bands separately double-counts, which is the most common error in a manual calculation.
The part that catches people is section 4AB. Once taxable income passes PKR 10,000,000, a 9% surcharge applies to the whole income tax bill — not to the excess. It is a cliff, not a taper, and crossing it by a single rupee costs PKR 241,290.
Tax year 2026 runs from 1 July 2025 to 30 June 2026, so it does not line up with the calendar year. A salary change in, say, March falls in the same tax year as the previous July.
