To Start an LLC in Colorado, Follow the Simple Steps Listed Below:

STEP 1: Name your LLC

This is the first and most important step in starting your LLC. Do some research to make sure the name you choose is suited to your business venture and is easily searchable for potential clients.

  1. Follow the Colorado naming guidelines: Your entity name must contain the words Limited Liability Company or the abbreviation L.L.C. or LLC. Restricted words require additional paperwork (e.g. Banc, Bank, Banque, etc) and/or licensed individuals (e.g. Doctor, Engineer, etc). to be part of the LLC. Prohibited words are those that would confuse the name of your LLC with a federal or state agency e.g. FBI, Secret Service, Treasury etc. Learn more about naming restrictions on the Colorado State Website.
  2. Is the name available in Colorado? Make sure the name isn't already taken by doing a name search on the State of Colorado website.
  3. Is the URL available? Check to see if the name of your LLC is available so that you can reserve your domain name. Even if you don't plan to make a website today, you may want to buy the domain name in order to prevent others from acquiring it.
