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:
- Miscellaneous Forms
- Extension Payment for Colorado Individual Income Tax, DR 158-I
Note: Electronic filing is not supported for the state extension payment at this time. The federal extension payment may be sent electronically, however the state extension payment will have to be mailed.
