Sales Tax invoice rules in Pakistan

In Pakistan an invoice must show your NTN, itemised lines, and Sales Tax separately at the applicable rate — 18%, with 18% applying to most work. A sales tax invoice quoting the NTN and, for provincial services, the provincial registration number. Large taxpayers are subject to real-time integration with the FBR system.

The Pakistan rule people miss

Sales tax on services is administered provincially rather than federally, so the rate and the registering authority depend on which province the service is delivered in. Sindh, Punjab, KP and Balochistan each run their own revenue authority with its own rate card.

When Sales Tax registration becomes compulsory

Federal sales tax on goods applies to manufacturers and importers with limited exemptions for cottage industry. Provincial service-tax thresholds vary by province and by service category.

Assessed on a rolling twelve months in most systems, not your financial year — which is the detail that catches people out.

Which Sales Tax rate applies to what

Provincial service rates are commonly in the 13–16% range, and several provinces apply a reduced rate — often around 5% — to specified services billed without input adjustment.

Bands are defined by what you supply, not by who buys it.

How often you file in Pakistan

Sales tax returns are monthly, with the annexures due a few days before the return itself around the middle of the following month. Registration also brings you into the withholding regime, where certain buyers deduct part of the tax and remit it directly.

A worked Sales Tax example

Invoice Rs 4,100 with a 5% discount shown on the document:

• Net before discount: Rs 4,100
• Discount at 5%: −Rs 205
• Taxable value: Rs 3,895
• Sales Tax at 18%: Rs 701.1
• Total due: Rs 4,596.1

The discounted value is what gets taxed — discounts, deposits and advance payments covers where that stops being obvious.

Correcting an invoice in Pakistan

Corrections run through prescribed debit and credit notes and are reflected in the return for the period in which they are issued. The adjustment window is finite, so a dispute settled long after the event can leave the tax stranded.

Invoicing outside Pakistan

Services rendered to a client in another province can create a genuine dispute about which authority is owed the tax. Where you deliver the service, not where you are registered, generally governs.

Charging tax to a client in another country covers the general shape.

The universal fields — number, both parties, dates, lines, tax separately, total — apply on top of the local rules above. Rates change: checked to mid-2026, a starting point rather than tax advice; verify against the Federal Board of Revenue.

Set your country once in EstimateBill and the tax is labelled correctly on every invoice after that — GST and GSTIN in India, VAT in the UK, Sales Tax and EIN in the US, across 58 countries.
