Hello Everyone,

Key Reminders for a Smooth Review Season

1. Please read the 2025 SFD Specifications.

2. Submit the 2025 LOI and wait for approval before submitting any forms.

   1. List all limitations on the LOI. 

   2. Limitation waivers are not guaranteed to be granted. 

   3. Limitations missing from the LOI will require a resubmission of the LOI.

3. 2D packets (when made available in November/December) should be sent to dor_efileadmin@state.co.us.

4. Subject of emails should be the NACTP number, vendor name and submission type. 

   1. I.e. 1234, Tax Form Vendor, New Submission.

   2. To make sure all forms intended for review are attached to the email, please include form numbers in the body of the email. We no longer accept a separate attachment with a list of forms to be reviewed.

   3. Once the review of the submitted forms has been completed, SFD Paper Review Team will use the original email to reply with the form status.

5. As of 2023, scanline forms may require 3 samples, depending on the form number. Make sure to review the SFD Specifications with the list of forms and required number of samples before submitting. If the incorrect number of samples are submitted, the submission will be rejected before any review has taken place. All non-scanline forms require 2 samples. 

6. Forms with bottom alignment limitations must use capitalized alpha characters. Forms with no such limitations may use X for letters and 0’s for numbers to show variable data placement. Exceptions for this nondescript data are Account Names, Account Numbers, Amount Dues, and Dates, where we request unique alpha numeric sample data.

7. Also, please note the DR 0158-I is now the DR 0158. The document name, barcode, and human eye readable must be updated.

Please let us know if you have any questions.

Thank you,

Substitute Form Developer Review Team

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,

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