The federal income tax filing deadline for individuals who requested an extension is October 15, 2026.
While this date grants you extra time to submit your paperwork without facing late filing penalties, it is important to remember the following specifics:
- Payment Deadline: An extension only pushes back your filing deadline, not your payment deadline. Any taxes owed were technically due by April 15, 2026, and unpaid balances accrue interest from that original date.
- Expats and Military: U.S. citizens living abroad or military personnel on duty outside the U.S. generally received an automatic grace period to June 15, 2026. Those who requested additional time using IRS Form 4868 also have until October 15, 2026.
- State Deadlines: Most states follow the federal October 15 deadline, but you should verify state-specific due dates and payment rules directly with your state’s tax agency.
