Realize This is Only Part of the Process
Getting your tax identification numbers is only part of the process. For the documentation of your corporation or limited liability company to be complete you will also need several internal documents, such as an operating agreement. You may also need to file additional tax forms, such as the forms needed to become an S corporation. Keeping all of this straight is why you need a team of advisors, including an attorney and tax advisor.
Complete Colorado Department of Revenue Form CR 100
The form needed to get a tax identification number is located on the Colorado Department of Revenue's website at http://www.colorado.gov/cms/forms/dor-tax/CR0100.pdf. The questions on the form are pretty much self-explanatory, and again your attorney or tax advisor can help you if you find any of the questions confusing.
Make two photocopies
You'll need to send the original and one photocopy to the Department of Revenue, so make an extra photocopy for your own records.
Deliver to the Colorado Department of Revenue
Once complete, you can either mail the form to the Colorado Department of Revenue or take it to any Taxpayer Service Center. In either case, you'll need to include a copy of your valid Colorado picture ID (license, etc.).
