FBR Digital Invoicing Extension (2026): What It Means and Who Can Give You One
FBR digital invoicing extension explained: the 20 June 2025 letter, the section 74 two-year cap, and why there is no add-on to download.
What this guide tells you, in plain words
People search for an FBR digital invoicing extension and mean four different things. Some want a new deadline. Some want more time for their own business. Some are hunting for a browser add-on to install. Some only want to know what file type FBR accepts. This guide answers all four.
FBR did publish one document with the word Extension in its name. It is a one-page letter dated 20 June 2025, file number F. No. 1(141) ST-L&P/2025/77394-R. It used section 74 of the Sales Tax Act 1990 to move corporate registered persons to 1 July 2025, and non-corporate registered persons to 1 August 2025. It still sits on FBR's own website.
Two more facts are worth knowing before you read on. Section 74 caps any extension at two years in aggregate. And FBR has never released a browser extension, plug-in or add-on for digital invoicing, so any file offered under that name is not FBR's.
Meaning one: the extension letter FBR actually published
Open fbr.gov.pk, go to FBR Digital Invoicing, then Digital Invoicing Legal Provisions. Checked live on 19 September 2026, that page lists exactly three documents. The third is titled Extension for Integration. That is the file most people are searching for.
It is a letter, not an SRO (Statutory Regulatory Order, a written order a body like FBR can issue on its own). It is addressed to the Chief Commissioners Inland Revenue. That covers the Large Taxpayers Offices, the Medium Taxpayers Office, the Corporate Tax Offices and the Regional Tax Offices. It carries the signature of a Second Secretary.
The wording is short. FBR says it is pleased to further extend the date of integration with the Board's computerised system. That means connecting through a license integrator or PRAL, as required under Rule 150Q of the Sales Tax Rules 2006. Below that sits a two-row table. Corporate registered persons: first day of July 2025. Non-corporate registered persons: first day of August 2025.
Here is the part most search results miss. That letter has been overtaken. A later order, SRO 1852(I)/2025 of 24 September 2025, set the final timetable, and the last group had to be live by 31 December 2025. So the June letter is history, not your deadline. 'SRO 1852(I)/2025 Explained: FBR Digital Invoicing Deadlines, the PDF, and Who It Covers' carries the current dates, and 'FBR E-Invoicing Deadline Extended: New Phase Dates by Turnover (2026)' shows how the phases moved.
Meaning two: can you still ask FBR for more time?
The June 2025 letter used section 74 of the Sales Tax Act 1990. That section is titled Condonation of time-limit. Condonation means officially excusing something that was done late.
Read what it allows. The Act or the rules may set a time for an application to be made, or for any act or thing to be done. Where they do, the Board may permit it to be done within such period as it considers appropriate. It may do so at any time before or after the original time has expired, in any case or class of cases.
Three limits matter. First, the power belongs to the Board. A Commissioner may use it only where FBR has empowered him by notification in the official Gazette. Second, the law caps it. The maximum period of extension under this section shall not exceed two years in aggregate. Third, this is a general power in the Act. There is no digital invoicing extension form, no button in IRIS, and no waiting list.
So the honest answer for most businesses is short. Every published digital invoicing date has already passed. You cannot grant yourself an extension, and no software seller can grant you one either. The duty itself comes from the rule, not from any SRO, and 'Rule 150Q of the Sales Tax Rules: The Legal Basis for FBR Digital Invoicing (2026)' explains where it sits in law.
Meanings three and four: nothing to install, no special file to upload
The other half of this search is people looking for a download. FBR's Digital Invoicing menu has seven items. They are Legal Provisions, Technical Assistance, User Manual, List of License Integrators, Licensing Committee, Digital Invoicing EOIs, and FAQs. Not one of them is a browser extension, a plug-in, an add-on or a setup file.
Treat that as a safety rule. Suppose a website, an advert or a WhatsApp forward offers you an FBR digital invoicing extension to install. Or it asks for money for one. It did not come from FBR. Never type your IRIS password into it. Never paste in your production token, which is the password-like key that lets software post real invoices.
The file-type question has a plain answer too. An FBR digital invoice is not a file you upload. Your software sends it as JSON, a plain-text format software uses to swap data. It travels over an API, which is a connection that lets two software systems talk to each other. FBR replies with an IRN (Invoice Reference Number, the unique number FBR gives each accepted invoice) and a QR code. Some programs let you import a spreadsheet to save typing, but that is the program's own feature, not FBR's format.

If you are already late, do this instead of waiting
Being late is common, and it is fixable. The steps do not change because a date was missed.
Register for digital invoicing inside IRIS. Pick PRAL or a licensed integrator from FBR's own published list. Then pass the sandbox test. Sandbox is FBR's free practice system, where test invoices do not count as real ones. Collect your production token. Then send every sale through, and print the IRN and the QR code on the face of the invoice.
Two habits help if a notice arrives later. Keep a dated screenshot of each step. Keep the email or portal record showing when your production token was issued. Together those show the date you actually went live, which is the only date that will matter in a hearing.
'How to Register for FBR Digital Invoicing (Step by Step)' walks through the registration itself. 'FBR Digital Invoicing Penalties in 2026: Fines, Deadlines and How to Stay Compliant' sets out what staying unconnected costs.
Digi Invoice connects your billing to FBR for you, so the run from first sandbox test to first live invoice takes days rather than weeks. Create a free account and post a practice invoice before you go live.
Difficult words in this guide
Extension: more time to do something the law already required. It moves the date, never the duty.
Condonation: officially excusing an act that was done late, or allowing it to be done after the deadline has passed.
Section 74: the part of the Sales Tax Act 1990 that lets the Board extend or excuse a time limit, capped at two years in aggregate.
Rule 150Q: the rule in the Sales Tax Rules 2006 that requires notified registered persons to connect to FBR's system through PRAL or a licensed integrator.
Production token: the password-like key that lets your software post real invoices to FBR, as opposed to practice ones.
