Start an Entity

Search for a Name

Before you form an entity in Colorado the first thing that we recommend doing is ensuring that the name you have selected for your entity is not currently in use, or is not too similar to a name currently on file with the Secretary of State. To check the availability of the name that you have selected you must perform a Business Entity Search. You can search the database in a number of ways, by name, trademark, trade name, ID number, document number, or registered agent name. If the name you have chosen is available for use, you will be presented with a page that confirms said availability and offers links to the forms that allow you to reserve said name.

How to File in Colorado

Step 1 – The very first thing that you should do, although not technically mandatory, is ensure that the name you have in mind for your entity is not already in use by another business operating in Colorado. To check your desired operating name’s availability, as previously mentioned in this tutorial, you must Search the Businesses Database. If the name you have chosen is available for use, proceed to the next step.

Step 2- With a name chosen and researched, you will have the opportunity to perform a Name Reservation. Again, this is not a mandatory step in registration but will simply enable you to secure the rights to your designated title for a period of 120 days while you prepare for registration. The filing fee will amount to $25.

Step 3 – You must now begin to complete the  application form associated with your particular entity type. The application forms are only available through the web portal located at the Colorado Secretary of State webpage. You cannot print them out and thus you cannot submit them by mail.

Note that all domestic entities will be required to pay $50 while foreign business can expect to pay $100.

Name Reservation

A Name Reservation is a very common filing that is available in most states across America. It enables filers to secure a business name prior to filing to give themselves ample time in which prepare for the registration process. The reservation is not a mandatory step but simply a precautionary measure to take if you feel as though your chosen operating name is common enough to be potentially filed by another entity. In Colorado, these reservations last for a period of 120 days and cost $25.
