Extension Filers Have Until Midnight Tonight to File 2025 Returns
October 15 is the last day to file without a late-filing penalty if you requested an extension. IRS Free File stays open through today.
Taxpayers who requested an extension in April have until today, October 15, to file their 2025 federal income tax returns. For most people with a valid extension, it is the last day to file without a late-filing penalty.
An extension to file was never an extension to pay. Tax owed was due April 15, so anyone filing now who still owes is already being charged interest on the balance. Filing today at least stops a late-filing penalty from being added.
IRS Free File is available through today for taxpayers whose 2025 adjusted gross income was $89,000 or less, and Free File Fillable Forms are available at any income.
If you cannot pay in full, file anyway and then set up a payment plan; our guide to IRS payment plans is in Tips & how-tos.
