Invoice Withholding Calculator – All in One
Enter your invoice details and see the whole picture in one place: income tax withholding under Section 153, an optional provincial sales tax on services, and what the supplier is actually paid. Each section works exactly like its own standalone calculator on this site — combined here so you only need one page per invoice.
1. Income Tax Withholding (Section 153)
Withholding tax under the Income Tax Ordinance, 2001 on a payment for goods, services or a contract — the same categories, sub-categories and Filer/Non-Filer rates as the standalone Income Tax WHT calculator.
2. Provincial Sales Tax on Services Optional
Provincial sales tax on services — the same category rates used by each province's own Sales Tax on Services calculator. By default this tax is simply added on top of the value of supply. If you're a notified withholding agent, turn on withholding below to also deduct a share of it from the supplier, exactly like each province's own Sales Tax Withholding calculator.
Worked Example: A Goods + Services Invoice
A company pays a filer/ATL-active supplier Rs. 500,000 for rice under Section 153, and separately owes Rs. 100,000 (excl. tax) for telecom services taxable in Sindh — and this time the company is also a notified SRB withholding agent for the registered telecom provider.
The Rs. 7,500 income tax and the Rs. 3,900 sales tax withholding are both deposited by the paying agent directly with FBR/SRB on the supplier's behalf and are creditable against the supplier's own returns. Both amounts are saved to My WHT Log. If withholding had been left off, the full Rs. 119,500 would simply be added to the invoice and paid to the supplier, with only the income tax portion logged.
Frequently Asked Questions
Why are income tax and sales tax shown together on one invoice?
A single payment can genuinely attract both: Section 153 income tax withholding on the payment itself (goods, services or a contract), and provincial sales tax on the services portion of the same invoice. They're separate laws with separate rules — this page runs the exact same calculations as the two standalone calculators, just side by side.
Why does the Income Tax Withholding amount depend on Category, Sub-category and Filer Status?
Section 153 (and the other WHT provisions bundled into this calculator) sets a different rate for practically every kind of payment, and almost every category has two rates — a lower one for suppliers on FBR's Active Taxpayer List ("filers") and a higher one, often roughly double, for those who aren't. Picking the right Category, Sub-category and Filer Status applies the correct rate instead of guessing.
When should I turn on provincial sales tax withholding?
Ordinary provincial sales tax on services is charged by the supplier and added to the invoice — by default the payer simply pays it along with the value of the service, and the supplier deposits it with the provincial revenue authority. Withholding a share of that sales tax only applies to notified withholding agents under each province's separate withholding regime. If that's you, turn on "Withhold provincial sales tax at source" in the Provincial card and pick the Withholding Category matching your supplier — the same rule the standalone Sales Tax Withholding calculator uses.
What gets saved to My WHT Log?
The WHT Log is a record of amounts actually withheld from a supplier and payable to a tax authority on their behalf. The income tax withholding portion is always logged when entered. The provincial sales tax portion is logged only when you turn on withholding for it — if it's left off, the full sales tax is simply added to the invoice with nothing withheld, so it's shown on screen and in the breakdown for your records but not saved as a separate withholding entry.
Where do the rates on this page come from?
They mirror the exact same data used by the standalone Income Tax WHT calculator and each province's own Sales Tax on Services calculator (Sindh SRB, Punjab PRA, KPRA, BRA, ICT), so the figures stay consistent no matter which calculator on this site you use.
