Colorado allows an automatic extension to October 15th, with-out filing an extension form. At least 90% of the net tax liability must be paid by the return due date (April 15th) to avoid a late payment penalty. To make a payment, use DR 0158-I, Extension Payment for Colorado Individual Income Tax
To access the Colorado Extension Payment, from the main menu of the Colorado state return, select:
- CO Miscellaneous Forms and Schedules
- CO Extension of Time to File
This form can be electronically filed in the TaxSlayer Desktop program.
