Delaware allows an automatic extension to October 15th by filing Form PIT-EXT. The form and payment of any balance of estimated tax liability due must be submitted by April 30.
To complete Form PIT-EXT in TaxSlayer ProWeb, from the Delaware Return menu select:
- Miscellaneous Forms
- Extension Form PIT-EXT
Note: Electronic filing is not supported in ProWeb at this time for the state extension payment. The federal extension request may be sent electronically, however the state extension payment will have to be mailed.
