Announcements Tax Year 2025

Hello Everyone,

Governor Polis has ordered a special session for the Colorado legislation. The session will begin August 21 and will last at least three days. 

Special session has the potential to affect Colorado state tax forms. Once the special session is complete and our team better knows the impacts, we will provide the substitute form development community with a start date regarding when "final" forms will be released for replication. Please note, not all forms are expected to be impacted by this special session. Some "draft" forms may be released as early as the end of next week on the Tax forms by year 2025 page.

Attached is a PDF of Governor Polis' special session executive order.

Thank you,

Hello Everyone,

It was brought to our attention that form DR 0619 was omitted from the 2025 Colorado LOI.

Please find attached a corrected version (v2) for use going forward.

• Vendors who have already submitted their LOI to us and plan to include DR 0619 in their submissions, please resubmit your LOI using the updated version. We apologize for the inconvenience.

• Vendors who have already submitted their LOI and DO NOT plan to include DR 0619, no action is needed.

We are also updating the LOI version on the Colorado Substitute Form Developed website. 

Please let us know if you have any questions.

Thank you,
