Sales tax invoice format in Pakistan: a field-by-field layout
Plenty of Pakistani businesses know they must issue a "tax invoice" but are unsure what it should actually look like — which fields, in what order, and how to show the tax. Getting the layout right matters for a concrete reason: an invoice missing required fields can cost your buyer their input tax claim and expose you at audit. This guide gives a practical field-by-field layout, explains how the tax line is presented, and shows how the format feeds FBR digital invoicing. It is the layout companion to the legal sales tax invoice requirements.
The fields, in order
A compliant sales tax invoice is built from a defined set of fields. Laid out top to bottom, a workable structure is:
- Header: the word "Tax Invoice", your business name, address and sales tax registration number (STRN) and NTN.
- Invoice reference: a sequential invoice number and the date of issue.
- Buyer block: the buyer's name, address, and — for a registered buyer — their registration number.
- Line items: description of goods or services, quantity, unit price, and value excluding tax.
- Tax block: the value of the supply, the sales tax rate, and the sales tax amount shown separately.
- Total: the gross amount payable including tax.
The buyer's registration number matters more than businesses expect: for a sale to a registered person, that number is what links your output tax to their input tax claim in the return-matching system.
Showing the tax line correctly
The single most important presentation point is that sales tax is shown separately. The invoice must let anyone reading it see three distinct figures: the value of the supply, the tax rate applied, and the resulting tax amount, before the gross total. This is not cosmetic:
- The buyer can only claim input tax if the tax is stated as a separate amount on a valid invoice.
- Your own output tax in the return is the sum of these separately-stated amounts.
- An "inclusive" price with no tax breakout is a common reason an input claim is disallowed and a common audit finding.
Holding input and output tax in their own ledger accounts — a point covered under the chart of accounts — means the tax figures on your invoices reconcile straight to the return.
We settle the taxable value, apportion input tax and file monthly with the right federal or provincial authority.

Sales tax invoices must be numbered sequentially, without gaps or reuse. The sequence is a control: it is one of the ways suppressed sales (a missing number) or duplicated invoices (a repeated number) are detected. A business issuing from several outlets or systems needs a numbering scheme that preserves one coherent sequence — for example a location prefix with a continuous run — rather than each point of sale generating its own overlapping numbers. Reconciling the invoice sequence to the sales recorded is a basic monthly check. It is also worth deciding in advance how cancelled or voided invoices are handled — the cleanest approach is to retain the voided number in the sequence marked as cancelled, rather than deleting it and leaving an unexplained gap that looks like a suppressed sale.
Feeding FBR digital invoicing
FBR has progressively extended digital invoicing to defined categories of registered persons, requiring invoices to be issued through the integrated system in a prescribed electronic format with real-time or near-real-time reporting. The practical implication for your format is that the fields above should map cleanly to the digital system's data points, so the same information that appears on a printed invoice populates the electronic one. Designing the layout with the digital fields in mind — even before the requirement reaches your category — means you are ready to integrate rather than rebuilding your invoicing later. The current scope and mechanics are covered in digital invoicing in Pakistan, and registration itself in sales tax registration.
Specimen invoice layout
A compliant tax invoice laid out as it would be issued. Every shaded heading is a required particular, not a design choice.
| Field | Specimen entry |
|---|---|
| Document title | SALES TAX INVOICE |
| Supplier name | Alpha Traders (Private) Limited |
| Supplier address | Plot 14, Industrial Estate, Lahore |
| Supplier registration number | 1234567890123 |
| Invoice serial number | STI-2026-000412 |
| Date of issue | 15 July 2026 |
| Buyer name | Beta Distributors |
| Buyer address | Shop 8, Hall Road, Rawalpindi |
| Buyer registration number | 9876543210987 |
| Description of goods | Steel fasteners, grade 8.8 |
| Quantity | 2,000 units |
| Value exclusive of sales tax | Rs 500,000 |
| Rate of sales tax | 18% |
| Amount of sales tax | Rs 90,000 |
| Value inclusive of sales tax | Rs 590,000 |
The arithmetic, both ways
| Starting from | Formula | Result |
|---|---|---|
| Exclusive value Rs 500,000 | 500,000 × 18% | Tax Rs 90,000; gross Rs 590,000 |
| Inclusive value Rs 590,000 | 590,000 × 18 ÷ 118 | Tax Rs 90,000; net Rs 500,000 |
The inclusive formula is where errors cluster. Applying 18% to a gross figure of Rs 590,000 gives Rs 106,200 — overstating the tax by Rs 16,200 on a single invoice and understating your own revenue by the same amount. Use the fraction, not the rate, whenever the price quoted already contains tax.
Where digital invoicing applies, the FBR-assigned invoice number and the verification QR code are additional required elements — see digital invoicing. The particulars above are the statutory minimum under section 23 of the Sales Tax Act 1990; nothing prevents adding purchase order references, delivery terms or bank details alongside them.

Questions people also ask
How should the sales tax amount appear on the invoice?
As a separate, clearly labelled line — not folded into the unit price or the total. The invoice should show the value of the supply, then the sales tax rate applied, then the sales tax amount as its own figure, then the gross total. Showing tax separately is what lets the buyer claim input tax and what the return and any audit expect; a price shown "inclusive" without breaking out the tax is a frequent cause of rejected input claims.
Do invoice numbers have to run in sequence?
Yes. Sales tax invoices should carry a sequential number with no gaps and no reuse. The sequence is part of how the system detects suppressed or duplicated sales, so a missing or repeated number is a red flag. Businesses that issue from multiple locations or systems need a numbering scheme that keeps the overall sequence intact rather than each outlet running its own overlapping numbers.
Is a printed invoice format still acceptable, or must it be digital?
It depends on whether your business falls within the FBR digital invoicing requirement, which has been extended progressively to defined categories of registered persons. Where digital invoicing applies, invoices must be issued through the integrated system in the prescribed electronic format. Even where it does not yet apply, designing your invoice with the digital fields in mind means you are ready when it does, rather than rebuilding the format later.
