How the calculation works on PKR 3,40,000 / month
Your annual gross of Rs 40,80,000 reaches the FY 2025-26 salaried slab 5. The marginal rate that applies to your next rupee earned is 30%, while your effective rate works out to 14.95%.
That works out to roughly Rs 50,833 a month deducted from your gross — leaving you with Rs 2,89,167 take-home. Your effective tax rate is 14.95%, even though your marginal rate is 30%.
What changes if you're not salaried?
Earning the same PKR 3,40,000 a month as a business owner or self-employed professional puts you under the non-salaried slab table — bracket rates rise meaningfully. IT exporters under the export-services regime go the other way: a flat 0.25% (PSEB-registered) or 1% (unregistered) on foreign-currency receipts.
