ISLAMABAD, August 7, 2026: The Federal Board of Revenue (FBR) has announced that its online tax return filing portal, IRIS, along with several other digital tax services, will remain temporarily unavailable over the weekend due to scheduled system maintenance.
In a public notice issued on Friday, the FBR said the maintenance will commence at 12:30 a.m. on Saturday, August 8, 2026, and continue until 5:00 a.m. on Monday, August 10, 2026.

During the maintenance period, taxpayers and other stakeholders will be unable to access several important online platforms, including:
• IRIS tax return filing portal

The FBR said all transactions linked to these services, including tax return filing, tax payments, registrations and other online activities, will remain unavailable throughout the scheduled maintenance window.
Taxpayers Advised to Plan Ahead
The tax authority has urged taxpayers, businesses and tax practitioners to complete any time-sensitive tax-related activities before the maintenance begins.
The FBR advised users to finalise:
• Income tax return filings.
• Tax payments.
• Registrations.

Planning ahead, the authority said, will help taxpayers avoid inconvenience during the temporary suspension of services.
Services to Resume After Maintenance
According to the FBR, all affected digital platforms are expected to become operational immediately after the successful completion of the maintenance work.
The revenue authority expressed regret for the temporary disruption and thanked taxpayers and stakeholders for their patience and cooperation.
