Estimate the withholding tax (WHT) a bank, broker, employer, telco, registrar, or buyer must deduct on a Pakistani transaction. Covers sections 148–236K with ATL filer and non-filer rates.
Pakistan's tax system collects a substantial portion of its income tax revenue at source - before the money reaches the taxpayer's hands. Sections 148 to 236K of the Income Tax Ordinance 2001 list dozens of transactions where the payer (an importer, a bank, an employer, a buyer, a telecom operator, a property registrar) is legally required to deduct tax from the gross payment and deposit it with the FBR within seven days. The recipient gets the net amount plus a withholding certificate that documents what was withheld.
For the recipient, that withholding is usually an adjustable advance against their annual tax liability. When they file their return, total WHT paid throughout the year is credited against the tax computed on their slab base. If they over-paid (common for salaried filers with significant bank profit), they get a refund. If they under-paid, they owe the balance. Some sections, though, are declared as final tax regimes - meaning the WHT deducted is the entire tax obligation on that income, and you can't claim it back even if you over-withheld.
For almost every WHT section, non-filers (people not on the Active Taxpayer List published weekly by FBR) pay substantially higher rates - often double, sometimes more. The intent is to penalise people who avoid the formal tax system by making informal transactions expensive. The practical effect is that the Active Taxpayer List has grown from about 1.5 million in 2018 to over 6 million by 2025.
A few common pairs:
A handful of WHT sections operate as final tax. The deduction is the only tax due on that income and it does not get added to your slab base. The most common ones to recognise:
Adjustable WHT is the opposite: the deduction is an advance, credited back to you in the annual return. Sections 153, 236C, 236K, 233, 235, and 231B are all adjustable for individuals.
A filer IT consultant invoices a corporate client PKR 200,000 for a one-off project. The client must deduct Section 153 services WHT at 11%.
WHT deducted = 200,000 × 11% = PKR 22,000. Client pays consultant PKR 178,000 net and issues a CPR showing PKR 22,000 deposited to FBR. The consultant declares PKR 200,000 as gross business income in their annual return, computes slab tax on total taxable income, and claims PKR 22,000 as adjustable WHT credit. Net effect: if the consultant's overall slab tax exceeded PKR 22k they pay the balance; if it was less they get a refund.
If the same consultant were a non-filer, the rate doubles to 22% and PKR 44,000 would be deducted - and the consultant could not get the excess refunded without first filing the return and going onto the ATL.
