Filing for tax year 2025–2026 (income year aligned with FBR’s published schedule) is smoother when documents are ready before the deadline. Use this checklist whether you file on IRIS yourself or through Aasaan Tax.
Documents to gather
CNIC and NTN details; salary certificate / payslips for the full year; bank statements; investment and insurance proofs; rent or property documents if applicable; prior-year return or wealth figures; withholding tax certificates; and business accounts if you have freelance or sole-prop income.
Before you submit
Confirm the official due date for your taxpayer type, reconcile employer-reported income with your records, complete the wealth statement, and keep PDFs of acknowledgements after IRIS submission. File early once salary certificates arrive — late filing risks penalties and delayed ATL benefits.
