Tax Training
and Resources

This list represents our logged Rules & Rulemaking and Guidance Publications Project work items. These work items are generated from our rule review process, our review of existing guidance publications, internal and external requests for rules or guidance publications, and rules necessitated by statute or new legislation. Because of our responsibility to maintain taxpayer confidentiality, this list does not represent all of our office’s ongoing work items. 

There are several useful columns in the chart, most of which are self-explanatory. The Status column can give you some indication where the office is in terms of working on a project. Work items that are “logged” have not yet been assigned to a staff member. “On deck” items will ideally be “in progress” in the next 5 to 6 weeks. A work item can be “in progress” for weeks, months, or sometimes more, depending on complexity. “On hold” projects are on hold for a variety of reasons, such as, more time sensitive projects need our attention, we are collaborating on the issue with other taxation units and the rulemaking is not yet ripe, or work by another taxation unit needs to be completed before the rulemaking can continue.

The Primary Requesting Group column shows where the work item came from. If no primary requesting group is noted, then the work item was added because our office identified the need.

If you have requested a work item from the Office, you are likely interested in knowing when the work item will be completed. There are many variables that go into determining this. The list is updated around the fifteenth of each month. It is our goal to add columns showing a target start date and project prioritization by December 1, 2021, which should provide you with a better sense of our forecasted timeframe. 

If you have requested that we on a project and you do not see the work item on the list, if you need help with any complicated or uncertain tax matter, if you have a suggestion for revising a guidance publication or a rule, or if you have expertise you would like to share with us, we welcome you to contact us! The best way to do so is to send an email to: dor_taxpolicy@state.co.us.
