As the 2026 filing season approaches, taxpayers across Pakistan are asking the same question: when is the income tax return for Tax Year 2026 due, and what happens if they miss it?

The Key Dates

For individuals, salaried persons, and Associations of Persons (AOPs), the income tax return for Tax Year 2026 is generally due by 30 September 2026. Companies typically have until 31 December 2026. These dates anchor the entire compliance calendar.

Why Filing On Time Matters

Filing by the deadline keeps you on the Active Taxpayer List (ATL), which means lower withholding tax on banking, property, and vehicle transactions. Late filers face penalties, default surcharge, and exclusion from the ATL until they file and pay any applicable surcharge.
