Once a valid electronic sales tax invoice has been generated, you cannot simply overwrite it. Sales Tax General Order (STGO) No. 01 of 2026, dated 30 March 2026, sets a 72-hour window for cancelling, deleting or editing a valid FBR e-invoice — and only where the invoice was generated due to a bona fide mistake, through the Board's computerized system. After those 72 hours, the same kind of change needs prior approval of the concerned Commissioner Inland Revenue.
This guide explains that official rule, the Invoice Dashboard conditions in PRAL's Digital Invoicing User Manual v1.6, the official IRIS application for amendments after 72 hours (published with FBR's letter of 5 November 2026), and how debit or credit notes under section 9 of the Sales Tax Act, 1990 remain a separate route. It does not replace advice on your own invoices.
What STGO 01 of 2026 says about cancel and amend

STGO 01 of 2026 (IR Operations) is a one-page general order issued in Islamabad on 30 March 2026. It is listed on FBR's official Sales Tax General Orders page for 2026. The order cites sub-sections (5) and (6) of section 23 of the Sales Tax Act, 1990 — the Board may require registered persons to integrate their electronic invoicing system with the Board's computerized system for real-time reporting of sales, and a licensed integrator carries out that integration — and records that S.R.O. 1413(I)/2025 dated 1 August 2025 obligated all sales tax registered persons to integrate through a licensed integrator and issue digital invoices.
The order also directs that a registered person may engage one or more licensed integrators, as approved or notified by the Board, wherever required.
On corrections, the operative direction is as follows. An integrated person shall only be allowed to cancel, delete or edit a valid electronic sales tax invoice generated due to a bona fide mistake, through the Board's computerized system, within seventy-two (72) hours from the time of its generation.
The proviso is equally clear: any such cancellation, deletion or editing after the expiry of seventy-two (72) hours from the time of generation shall be subject to prior approval of the concerned Commissioner Inland Revenue, in such manner and subject to such conditions as may be specified by the Board.
Three points follow directly from that text:
- The 72-hour clock runs from the time of generation of the electronic sales tax invoice.
- The self-service cancel, delete or edit path is limited to a valid invoice generated due to a bona fide mistake, and must go through the Board's computerized system.
- After 72 hours, those same kinds of change need prior CIR approval, in the manner and on the conditions the Board may specify.
How to cancel or edit an e-invoice within 72 hours
For the window inside those 72 hours, the official public description of the self-service path is PRAL's Digital Invoicing User Manual, Version 1.6 (last updated 16 April 2026 — after STGO 01). It is published on PRAL's DICRM downloads page. The manual documents the Invoice Dashboard, including the invoice cancellation process and the system's conditions and validations. That dashboard path is the “self-correct” route shown in the comparison above: you act through FBR's system, not by informal back-end changes.
Invoice Dashboard: search, status and item-level changes
According to the manual, invoices can be searched by FBR Invoice Number or by a date range. Statuses include Valid, Edited, Cancelled, Partially Edited, Partially Cancelled, and Partially Edited & Cancelled. On the PDF invoice, “C” means Cancelled and “E” means Edited.
You may cancel an entire invoice, or cancel or edit an individual item. These limits apply:
- “Cancel All” is enabled only if none of the items have been edited.
- Once an item has been edited, it can no longer be cancelled, and the entire invoice containing that item is also ineligible for cancellation.
- Each item may be edited only once.
- Original item details remain viewable after editing.
Official conditions for invoice cancellation
The manual's “Conditions for Invoice Cancellation” set out the validations for this dashboard path, including:
- Only e-invoices received through DI Integration are eligible for correction.
- Corrections must be made within 72 hours of issuing the invoice (Insertion Date) — the manual's wording for this system check. STGO 01 itself measures the 72 hours from the time of generation.
- The invoice number is fixed and cannot be modified.
- Only individual item details can be edited; header information remains fixed.
- The invoice date cannot be revised to a date earlier than 3 days before the current system date.
- Invoices linked with Annexure-C are not eligible for correction.
- Invoices that have already been reported in submitted returns cannot be changed.
- Invoices are moved to the return after 72 hours of invoice posting time or at month end, whichever comes first, and cannot be cancelled afterward on this dashboard path.
- Invoice cancellation is allowed only when its value does not exceed 10% of last month's sales. Once that limit is exhausted, no further invoices can be cancelled. The 10% limit is a total limit for all invoice modifications together, whether you change one invoice or item or several.
- After modification, a revised invoice is generated, retaining the original number and date.
Read the “cannot be cancelled afterward” line with care. It describes the Invoice Dashboard self-service path. It does not repeal STGO 01's proviso that, after 72 hours, a cancellation, deletion or edit may still be made with prior approval of the concerned Commissioner Inland Revenue. The official IRIS application for that approval is set out below.
What to do if 72 hours have already passed
If the 72-hour window has expired, do not assume the invoice can still be changed from the Invoice Dashboard. The after-72-hour manual states that the taxpayer can no longer edit or cancel the invoice in DI itself. STGO 01 requires prior approval of the concerned Commissioner Inland Revenue, in such manner and subject to such conditions as may be specified by the Board.
FBR has now published that manner. On 5 November 2026, the Board's IT & DT Wing issued a letter (C.No.18(1)/POS/IR/2026-Pt (DI Statistics)/125773-R) circulating user manuals for amendment of sales tax electronic invoices, including PRAL's Amendment in Electronic ST Invoice (TP) – User Manual, Version 1.0. The letter and manual are on FBR's website under User Manuals and Implementation of the Sales Tax Electronics Invoices Management System and as a direct PDF. The facility lets a taxpayer edit or cancel a valid electronic sales tax (DI) invoice after 72 hours, provided the concerned CIR approves.
The 20 November 2026 cut-off
The same FBR letter directs that 20 November 2026 is the cut-off date. From then on, FBR will handle cases and complaints about Digital Invoicing only through the newly developed portal, and will not accept requests for back-end deletion of invoices. If you need to cancel or amend an invoice after 72 hours, use the IRIS application described below — and consult a qualified tax advisor on your own facts.
How to apply in IRIS after 72 hours
The taxpayer manual sets out these steps. Always confirm them against the current official PDF or what you see in IRIS, as screens can change.
- Go to https://iris.fbr.gov.pk/, enter your CNIC or NTN and password, and log in.
- Open the Sales Tax drop-down, go to Applications, and click Application for Amendment in Electronic Sales Tax Invoice (after 72 hrs).
- Search for and select the tax period, then click Continue. The application window opens.
- Go to DI Sale Invoice and click Add Invoice.
- Enter the FBR Invoice Transaction Number and click Search. This is the Master Invoice Number in DI: the part before the hyphen (-) in Invoice Management for the selected tax period.
- Select the invoice and click Load For Modification or Load For Discard, depending on whether you need to amend or cancel it.
- To amend: select the invoice, click Edit, change the details, and click Save Item. The manual notes that an invoice that has been edited cannot be cancelled, and an invoice that has been cancelled cannot be edited. The FAQ likewise says an invoice cannot be both amended and cancelled in the same application.
- To cancel: select the invoice, click Delete, and click Yes to confirm. The manual says the selected invoice will be deleted/removed. You must still click Submit, and CIR approval remains mandatory.
- Optionally, open the Attachment tab, click +, attach a PDF file, and click Ok. The manual's FAQ says taxpayers can attach supporting documents in PDF format — the wording is permissive, not mandatory.
- Click Submit to finalise the application.
CIR approval is mandatory for every post-72-hour amendment or cancellation.
If the tax officer asks for clarification
Once the application has been submitted, the tax officer may request clarification through Internal Correspondence. To reply, the manual's path is: Outbox → Sales Tax tab → the application → Assignment tab → select the assignment → Reply → Clarification Provided → enter a description → Save.
The decision, and what happens to Annexure-C
After receiving the application and reviewing any clarification, the tax officer can accept or reject individual invoice items, or several items at once, through “Accept/Reject Application for Amendment in Electronic Sales Tax Invoice (After 72 Hours)”.
- Annexure-C cannot be submitted while the CIR's response is pending. If you go to Annex-C (Sales), choose Load Sales and Submit, the system shows an error.
- Once the CIR approves, the edited invoices load into Annexure-C. The FAQ adds that an approved, amended invoice is available for Annexure-C subject to system validations.
- If the CIR rejects the application, the original invoice — as it stood before the amendment or cancellation — is loaded into Annexure-C and, where applicable, the Federal Excise Return.
Eligibility conditions for the after-72-hour application
The manual's “Conditions for Amendments in Electronic Sales Tax Invoice (After 72 hrs)” include:
- No application can be submitted for an invoice that is already linked to Annexure-C of the Sales Tax Return or to the Federal Excise Return, or that the CIR has already approved under another application.
- Several applications may be made for the same tax period, but invoices already submitted, or rejected by the CIR, cannot go into a new application.
- An invoice whose CIR decision is pending cannot be included in any other application.
- If the CIR rejects, the original invoice loads into Annexure-C and, where applicable, the Federal Excise Return, as noted above.
Keep a clear record of the invoice, the time it was generated, and the bona fide mistake you need to correct, and consult a qualified tax advisor before you apply.
Debit and credit notes are a separate legal route
Correcting a bona fide mistake on a valid e-invoice under STGO 01 is not the same thing as adjusting a supply that later changed. Section 9 of the Sales Tax Act, 1990 remains a separate statutory route. Where a tax invoice has been issued and, because of cancellation of the supply, return of goods, a change in the nature or value of the supply, or some such event, the amount in the invoice or the return needs to be modified, the registered person may — subject to conditions and limitations the Board may impose — issue a debit or credit note and make a corresponding output-tax adjustment. A Finance Act, 2026 proviso says issuance of debit and credit notes shall be governed by the mechanism, including electronic adjustments, as may be prescribed by the Board. (See the official Sales Tax Act, 1990, updated to 30 June 2026.)
Chapter XIV of the Sales Tax Rules, 2006, substituted by S.R.O. 69(I)/2025 dated 29 January 2025, already required debit notes and credit notes to be issued electronically through the integrated system. S.R.O. 1666(I)/2026 dated 29 September 2026 later substituted rule 150S(2) so that the debit note, credit note and advance receipt invoice shall also be issued electronically. Chapter XIV does not itself contain the 72-hour time limit; that limit is in STGO 01. (The compiled Sales Tax Rules, 2006, updated to 6 August 2025, pre-date the 2026 amendments, including S.R.O. 1666.)
If the event is a genuine return, a cancelled supply, or a change in value or nature, talk to your tax advisor about an electronic debit or credit note under section 9 — not about treating it as a STGO 01 “bona fide mistake” edit of the original invoice.
Check the invoice before you post it to FBR

The surest way to stay inside the 72-hour rule is not to need it. Once a valid electronic invoice has been generated, STGO 01 limits how it can be cancelled, deleted or edited, and the dashboard validations above narrow that path still further. Header fields are fixed, the invoice number cannot be changed, a revised invoice keeps the original number and date, and invoices already linked to Annexure-C or included in a submitted return are not eligible for dashboard correction. After 72 hours, an IRIS application also cannot be made for an invoice already linked to Annexure-C or the Federal Excise Return.
Chapter XIV also matters here. Rule 150R(4)(g) requires the electronic invoice issuing machine to record every adjustment, modification or cancellation and to maintain logs. Rule 150R(5) provides that Annexure-C of the sales tax return shall be auto-filled from the electronic invoices issued by the integrated person. A mistake that reaches FBR can flow into the return and into your buyer's records.
Before you post, check the invoice carefully — in particular the details that are hard or impossible to change later on the dashboard:
- Buyer registration details (NTN or CNIC). PRAL's Digital Invoicing User Manual v1.6 states that the buyer's registration number is mandatory for a sale invoice.
- Item details such as HS code, quantity, value and the applicable tax rate. Item lines can be edited only once on the dashboard path, and cancellation there is subject to the 10% of last month's sales cap.
- Invoice date, because header information remains fixed and the date cannot be revised to earlier than 3 days before the current system date.
That pre-post check is practical guidance, not a separate official FBR form. The legal constraints are the ones in STGO 01, PRAL Manual v1.6, and the after-72-hour IRIS manual.
Frequently asked questions
Can I cancel or amend an FBR e-invoice after it is generated?
Yes, but only on the terms in STGO 01 of 2026. A valid electronic sales tax invoice generated due to a bona fide mistake may be cancelled, deleted or edited through the Board's computerized system within 72 hours from the time of its generation. That Invoice Dashboard path is also subject to the validations in PRAL's Digital Invoicing User Manual v1.6. After 72 hours, you may apply in IRIS for amendment or cancellation, subject to prior CIR approval.
What happens if more than 72 hours have passed?
You can no longer edit or cancel the invoice in the DI Invoice Dashboard. Under STGO 01 of 2026, any such change shall be subject to prior approval of the concerned Commissioner Inland Revenue. The official path is the IRIS menu Sales Tax → Applications → Application for Amendment in Electronic Sales Tax Invoice (after 72 hrs), as set out in PRAL's after-72-hour taxpayer manual circulated with FBR's letter of 5 November 2026. Consult a tax advisor on your own facts.
Can I submit Annexure-C while an after-72-hour application is pending?
No. The after-72-hour manual states that Annexure-C cannot be submitted while the CIR's response is pending. Once the CIR approves, edited invoices load into Annexure-C, subject to system validations. If the CIR rejects, the original invoice is loaded into Annexure-C and, where applicable, the Federal Excise Return.
Does the 10% of last month's sales cap apply?
Yes, on the within-72-hour Invoice Dashboard path. PRAL Manual v1.6 states that invoice cancellation is allowed only when its value does not exceed 10% of last month's sales, and that this 10% figure is a total limit for all invoice modifications together. That published cap is part of the dashboard validations. It is not stated in STGO 01 itself, and it is not listed among the conditions in the after-72-hour IRIS manual.
Can I correct an invoice that is already on Annexure-C?
Not through the Invoice Dashboard path in PRAL Manual v1.6: invoices linked with Annexure-C are not eligible for correction, and invoices already reported in submitted returns cannot be changed. The same bar applies to the after-72-hour IRIS application: no application can be submitted for an invoice already linked to Annexure-C of the Sales Tax Return or to the Federal Excise Return, or already approved by the CIR under another application. Ask your tax advisor about your specific invoice.
Is a debit or credit note the same as cancelling the e-invoice?
No. Section 9 of the Sales Tax Act, 1990 is a separate route for cases such as cancellation of the supply, return of goods, or a change in the nature or value of the supply. Debit and credit notes are now also to be issued electronically. That is a different legal event from cancelling or editing a valid invoice that was generated due to a bona fide mistake under STGO 01.
