What happens if my POS goes offline and cannot report sales to FBR in real time?

What does the law say?

Three layers apply when an integrated POS stops reporting.

The reporting duty in the Act. The proviso to section 23(6) of the Sales Tax Act, 1990 requires all Tier-1 retailers, from the date and in the manner the Board prescribes, to integrate their retail outlets with the Board’s computerized system “for real-time reporting of sales”.

How the POS must work. Rule 150R(4) of the Sales Tax Rules, 2006 says the POS machine shall transmit invoice data to the Board’s computerized system and receive the unique FBR invoice number, then print a QR code based on that number on the receipt. Rule 150R(3) says no supply shall be made except through integrated outlets or POS machines.

What to do when it fails. Rule 150XA makes the integrated person responsible for the smooth functioning of the hardware and software, and requires two kinds of report:

• to the Board and the concerned Commissioner, within twenty-four hours of any operational failure, damage, disruption or tampering of the system; or
• to the Commissioner with jurisdiction, within twenty-four hours, reporting any inoperative invoicing hardware or software with reasons and documentary evidence.

When can an outage lead to sealing?

Rule 150ZEO, as amended in February 2025, lists grounds on which the Commissioner shall seek the Chief Commissioner’s written approval to seal an integrated Tier-1 retailer’s premises. Alongside unverified invoices, three relate to going offline:

Trigger in rule 150ZEO(4)	Time limit
Store disconnected from the FBR database	Forty-eight hours
Invoices of the offline period not entered in the system	Within the next twenty-four hours
Device does not keep a record of invoices during the offline period	No time limit; the failure itself is the ground

The Chief Commissioner then allows or disallows sealing and decides whether one branch or more is affected. Once sealed, reopening under the de-sealing rule for integrated retailers requires an order imposing the penalty under serial 24 of the section 33 table, which is Rs. 500,000 or 200% of the tax involved, whichever is higher.

How does it work in practice?

Read together, the rules describe a sequence rather than a single deadline:

1. The POS loses connection. The rules expect the device to keep recording invoices while offline.
2. Within twenty-four hours of the failure, the retailer reports it under rule 150XA.
3. If the store stays disconnected for forty-eight hours, that is itself a ground for a sealing request.
4. Invoices issued while offline must be entered in the system within the next twenty-four hours.

The rules do not say when the twenty-four hours for entering offline invoices starts. Reading it from the end of the offline period is one possibility, but the text does not state it, and this page does not settle it.

Worked example (illustrative scenario)

Sana runs an integrated Tier-1 bakery-and-grocery outlet in Karachi. The times are invented; the time limits are those in the rules.

Event	Time (illustrative)	Rule consequence
Internet link fails; POS keeps recording offline	Monday 10:00	Offline records must be kept
Latest time to report the failure	Tuesday 10:00	Twenty-four hours under rule 150XA
Connection restored	Tuesday 18:00	Offline period ends after 32 hours
Offline invoices uploaded	Wednesday 11:00	17 hours after reconnection

Check: Monday 10:00 to Tuesday 18:00 is 24 + 8 = 32 hours, below the forty-eight hour trigger. Tuesday 18:00 to Wednesday 11:00 is 6 + 11 = 17 hours, inside twenty-four hours if the clock runs from reconnection.

Had the link stayed down until Wednesday 10:00 or later, the store would have been disconnected for forty-eight hours, which is a listed ground for a sealing request.

What if the POS hardware breaks rather than the internet?

Rule 150XA(d) covers this directly: inoperative electronic invoicing hardware or software must be reported to the Commissioner with jurisdiction within twenty-four hours, with reasons and documentary evidence. Rule 150XA(b) places responsibility for smooth functioning of all hardware and software on the integrated person.

Common mistakes

• Waiting for the connection to return before reporting. The twenty-four hours in rule 150XA runs from the failure, not from repair.
• Using a device that keeps no offline record. A device that does not keep invoice records during the offline period is itself a ground under rule 150ZEO.
• Treating 48 hours as a grace period for everything. The forty-eight hours applies to disconnection. The reporting duty and the offline-invoice entry each carry twenty-four hours.
• Switching to an unintegrated counter. Rule 150R(3) allows supplies only through integrated outlets or POS machines.

What to check in the official text

Read rules 150R, 150XA and 150ZEO of the Sales Tax Rules, 2006 as amended to 30 June 2025, and section 23 of the Act as amended to 30 June 2026. The rules do not define “operational failure” or say whether a power or internet outage counts, and they name no form or channel for the report. Any Sales Tax General Order or FBR instruction on offline mode is outside this site’s corpus.
