Automatic Filing Extension
Colorado offers an automatic 6-month extension to file your income tax return if you cannot submit your return by the April 15 due date. This means that you can file your return by October 15 without filing this form. While there is an extension to file, there is not an extension to the payment due date. Penalty and interest are assessed if certain payment criteria are not met. Please review FYI-General 11 for more information on penalty and interest. If you must wait until October 15 to file your return, use the following worksheet to calculate whether you need to remit a payment on April 15.
Persons Traveling or Residing Abroad
If you are traveling or residing outside the United States on April 15, the deadline for filing your return is June 15, 2021. The extension due date for filing remains October 15, 2021
