Uploading Extension Requests

*Important Notice*
For tax years beginning on or after January 1, 2022, Act 410 of the 2022 Regular Legislative Session changed how an extension is granted. If you know you cannot file your return by the due date, you do not need to file for an extension. You will automatically be granted an extension of six months except for Corporation Income & Franchise Tax. No paper or electronic extension form needs to be filed to obtain the automatic extension. For more information see “Requesting an Extension of Time for Filing a Return” on the webpages for Individual Income Tax, Corporation Income & Franchise Tax, Partnership Tax, and Fiduciary Income Tax.
