Filing Requirement Changes for Partnerships and S Corporations

Effective tax year 2022, Partnerships and S Corporations are required to provide Colorado K-1s (DR 0106K) for each of their partners or shareholders for each tax year. In prior years, only Part III of the DR 0106 was required.

For tax years 2022 and later, the partnership or corporations must complete the Colorado K-1 (DR 0106K) for each of their partners or shareholders.

Submission of Colorado K-1s by Partnerships and S Corporations

Completed Colorado K-1s must be filed with the Department, as described below. On or before the date the Colorado K-1s are filed with the Department, the Partnership or S Corporation must furnish each partner or shareholder with a copy of the Colorado K-1 reporting their income, deductions, modifications, and credits. 

Due Dates

Colorado K-1s are due to be filed the fifteenth day of the fourth month after the close of the tax year, or after the automatic six-month extension, if applicable. Colorado K-1s are due on April 15 every year. If the due date falls on a weekend or federal holiday, the Colorado K-1s will be due the next business day. 

Before filing the DR 0106K please review all of the form instructions included with the form, found at, under forms. The DR 1706 is not needed if you are filing the DR 0106Ks electronically as outlined below.
