Most calendar-year taxpayers who received an extension for their 2025 individual federal return have until October 15, 2026, to file.
An extension gave you additional time to submit the return.
It did not extend the original deadline to pay taxes owed.
If your return is still incomplete, begin gathering:
* W-2s and 1099s
* Business income and expenses
* Dependent information
* Health-insurance documents when applicable
* Prior-year tax information
* Estimated-tax payment records
* Any IRS notices you received
Do not wait until the final week to discover that information is missing.
