Top 5 Tips on Registering a Business in Colorado

  1. The Colorado Secretary of State requires filing formation documents online; paper forms are not accepted. You can look at a sample and instructions before you file.
  2. The great news about filing online is you'll find out right away if your formation is approved. Immediately after formation setup Secure Business Filing on your record so that no one else can make changes to it. Also remember to print out a paper copy for your records (and to bring to the bank to open a business bank account).
  3. The Colorado Department of Revenue offers a consolidated state tax registration application online or you can file two registrations by mail.
  4. Colorado makes filing annual reports a breeze. You can sign up for an e-mail reminder from the Secretary of State. Then you file online (no paper forms).
  5. Starting a business in Colorado is amongst the easiest of states. The process is straight-forward, you can file entirely online, and the fees are more than reasonable. Know that if one day you expand your business beyond the borders of Colorado, at that point you might be shocked at what it takes to register in other states.
