FBR Announces Planned System Maintenance: IRIS and Allied Services Temporarily Unavailable
Published on: August 08, 2026
The Federal Board of Revenue (FBR) has officially issued an important notice regarding a scheduled system maintenance activity that will temporarily disrupt digital services across the country. Taxpayers, legal consultants, and business owners who frequently interact with the tax portal need to take note of the downtime to plan their tax filings, returns, and digital submissions accordingly.
Key Details of the Maintenance Window
To ensure system stability, security enhancements, and optimal performance, the FBR infrastructure will undergo crucial upgrades.
Start Date & Time: August 8, 2026, at 12:30 AM PST
End Date & Time: August 10, 2026, at 5:00 AM PST
Affected Services: The IRIS portal and all of its allied online services will remain temporarily unavailable throughout this duration.
Impact on Taxpayers and Professionals
Because the IRIS portal serves as the primary backbone for filing income tax returns, sales tax statements, withholding tax statements, and responding to various departmental notices, this temporary suspension will halt all online transactional activities.
Filing Deadlines: Taxpayers who have pending submissions or upcoming deadlines falling within this maintenance window should aim to complete their tasks ahead of time or plan accordingly once the system is restored.
System Access: Attempts to log into the portal, verify active tax status (ATLR), or submit digital payments during the maintenance period will encounter service interruptions.
Official Support and Helpline
The FBR has expressed regret for any inconvenience caused to taxpayers due to this necessary technical upgrade. For urgent guidance, technical support, or inquiries during the downtime, users can contact the official FBR Helpline through their dedicated call center number:
Call Center UAN: 051-111-772-772
Taxpayers are encouraged to complete their urgent portal-related tasks immediately after the maintenance concludes on August 10, 2026, at 5:00 AM PST, when all services are expected to resume normal operations.
