FBR Digital Invoicing Integration Schedule 2026: Phases by Turnover
FBR is rolling out mandatory digital invoicing in turnover-based phases — largest taxpayers first, remaining registered persons last. Here is how the phased registration, testing and go-live schedule works and how to find your date.
A phased rollout, largest taxpayers first
Rather than a single switch-on date, FBR sequences integration in phases so its systems and taxpayers can absorb the change. The pattern moves from the largest and most sophisticated taxpayers to the broad base of remaining registered persons.
The current phased schedule flows from SRO 1852(I)/2025, which sets, for each category, a date to register, a date to complete sandbox testing, and a date from which live e-invoicing becomes mandatory.
How the turnover bands are ordered
The earliest phase typically covers public limited companies and all importers, followed by very large taxpayers — for example those with turnover above Rs 1 billion. Mid-size companies, such as those with turnover between Rs 100 million and Rs 1 billion, fall into a later phase.
The final phase sweeps in all other registered persons — the long tail of smaller businesses — with their own register, test and go-live dates. This ordering means a business's exact deadline depends on its category and turnover band.
The three steps in every phase
Whatever your band, the sequence is the same: first register your business for digital invoicing on the FBR portal; second, complete sandbox testing so your invoices validate cleanly against FBR's rules; third, switch to production and issue live, QR-stamped invoices from your go-live date.
Leaving sandbox testing to the final days is the most common cause of missed go-live dates, because configuration and data issues surface exactly then. Testing early is the single best way to be ready on time.
Dates move — always confirm yours
FBR has extended these deadlines more than once as compliance caught up, and later notifications continue to adjust the schedule. Any specific date you read online may already have shifted.
Confirm the current register, test and go-live dates for your exact category directly on the FBR portal (iris.fbr.gov.pk) or with your tax advisor before you plan your rollout.
Be ready before your phase, not on it
The safest approach is to integrate and clear sandbox testing well ahead of your category's go-live date, so live posting is a formality rather than a scramble. A ready platform turns integration into a same-day task instead of a development project.
Digi Invoice supports both FBR sandbox and production on the DI API v1.12, so you can test, verify and go live with confidence whenever your turnover band is due.
