Each year, “Tax Day” is April 15th & E-File Shuts Down on October 15th.
Each year, the deadline to file a tax return is April 15th. However, the e-file tax season doesn’t officially end until October 15th.
October 15 also marks the due date for filers who requested a tax extension.
That means, you must either file your return or request an extension by April 15th.
You can either e-file your return or mail in a paper return by the tax deadline. Note that if you are filing a paper return, your return must be postmarked by April 15th in order for it to be considered on time.
