Taxpayers can submit annual returns through the IRIS portal as FBR urges timely and accurate compliance before the September 30 deadline
ISLAMABAD: The Federal Board of Revenue (FBR) has announced that its Income Tax Return filing portal for Tax Year 2026 will officially open on Monday, July 27, 2026, enabling taxpayers across Pakistan to submit their annual income tax returns through the IRIS online system.
In an official statement issued on Friday, the FBR urged individuals and businesses to file their tax returns accurately and honestly, emphasising that timely compliance is essential for strengthening Pakistan’s tax system.
“Income Tax Return filing for Tax Year 2026 will open from Monday, July 27, 2026. All taxpayers are advised to file their returns accurately and honestly, ensuring that all declared information is true and correct. Timely and truthful compliance strengthens the tax system for everyone,” the FBR said.
IRIS portal ready for Tax Year 2026
With the commencement of the filing season, taxpayers will be able to prepare and submit their income tax returns electronically through the FBR’s IRIS portal.
Earlier this year, the tax authority issued draft income tax return forms for Tax Year 2026 through SRO 835(I)/2026, dated May 7, 2026, inviting feedback from stakeholders before finalising the forms.
The opening of the filing portal follows the implementation of the Finance Act, 2026, which introduced several measures aimed at broadening the tax base, improving documentation and strengthening tax compliance.
September 30 filing deadline
Under the existing filing schedule, the due date for submitting income tax returns for Tax Year 2026 is September 30, 2026.
The deadline applies to:
• Salaried individuals
• Business individuals
• Associations of Persons (AOPs)
• Companies with a financial year ending on December 31
The FBR has advised taxpayers to organise their financial records, income statements and supporting documents well before the deadline to ensure smooth and timely filing.
Stricter penalties for late filers
The Finance Act, 2026 has significantly strengthened the tax compliance framework by introducing higher penalties for taxpayers who fail to submit their returns within the prescribed deadline.
According to the FBR, the tougher enforcement measures, together with enhancements to the digital filing system, are expected to increase the number of active taxpayers and improve voluntary compliance during the Tax Year 2026 filing season.
The tax authority reiterated that accurate and timely filing of income tax returns remains essential for broadening the tax base, improving revenue collection and supporting Pakistan’s fiscal sustainability.
