FBR E-Invoicing Deadlines 2026: Who Must Comply and When

What are the FBR e-invoicing deadlines for 2026?

FBR's mandatory e-invoicing was phased in by taxpayer category through the end of 2025 under SRO 1852(I)/2025. Large taxpayers and importers went live on 1 November 2025, mid-size companies on 15 November 2025, smaller companies on 1 December 2025, and all other registered persons by 31 December 2025. As of 2026, every sales tax registered person is in scope.

FBR e-invoicing deadlines by turnover band

The following table summarises the live-by dates set out in SRO 1852(I)/2025 (24 September 2025), the current SRO that superseded SRO 709(I)/2025 and SRO 1413(I)/2025:

Each band had earlier registration and sandbox-testing milestones in the weeks before its go-live date, but the dates above are when issuing compliant electronic invoices became mandatory.

Who is in scope for FBR e-invoicing?

The scope is broad: every person registered for sales tax in Pakistan falls under the regime once their band's deadline passes. The rollout deliberately captured all registered persons — from public companies and importers down to small registered businesses — so that by 31 December 2025 there was no remaining "not yet required" category. If you hold a sales tax registration number (STRN) and issue invoices, you are required to issue them through FBR's integrated system. For what non-compliance costs, see our FBR e-invoicing penalties guide.

What does "integrated person" mean under the rules?

An "integrated person" is a registered person whose invoicing hardware and software are connected to FBR's computerised system so that invoices are transmitted in real time and receive a unique FBR invoice number (IRN) and QR code. The legal basis is Rule 150Q of the Sales Tax Rules 2006 (Chapter XIV). Integration can be achieved either directly through PRAL (Pakistan Revenue Automation Pvt Ltd, FBR's IT arm, which is free) or through a licensed integrator — and under STGO 01/2026, FBR now permits the use of multiple licensed integrators. To understand the technical output of integration, read what an IRN, QR code, and PRAL are.

What is the 72-hour rule introduced in 2026?

STGO 01/2026 clarified that once an electronic invoice is issued, it can only be edited or cancelled within 72 hours for genuine errors. After that window, any correction requires prior approval from the relevant Commissioner of Inland Revenue. This makes accuracy at the point of issuance important: your invoicing system should capture buyer details, tax rates, and amounts correctly the first time, because corrections become procedurally harder once the 72 hours elapse.

What should you do if you missed your e-invoicing deadline?

If your band's deadline has already passed and you are not yet issuing FBR e-invoices, treat it as urgent — enforcement of penalties has been in effect since January 2026. The practical steps are:

1. Confirm your category and deadline from the table above so you know how overdue you are.
2. Integrate immediately — either directly with PRAL or through a software provider that submits to the PRAL gateway — so new invoices start carrying a valid IRN and QR code.
3. Start issuing compliant invoices right away; every compliant invoice from today reduces ongoing exposure.
4. Reconcile your records and consult a tax advisor about any period you invoiced outside the system, since penalties can escalate for repeated default.

InvoiceFlow can shorten this to a same-day task: it submits your invoices through FBR's official PRAL gateway API and returns the real-time IRN and QR code for each one. See the full FBR compliance guide for the wider picture.
