Corporate name

The name must contain the word "Corporation," "Company," "Incorporated," "Limited" or an abbreviation thereof, provided that if "Company" or "Co." is used, it may not be immediately preceded by the word "and" or the symbol "&." It may not contain any word or phrase indicating or implying the corporation is organized for any purpose other than one or more of the purposes contained in its Articles of Incorporation. It may not be the same as or deceptively similar to that of a domestic corporation or a qualified foreign corporation or a reserved name, with qualified exceptions. The words "Engineer" and "Survey" require approval by the engineering board.

Director information

The following are Idaho’s requirements for directors of corporations:

  • Minimum number. Corporations must have one or more directors.
  • Residence requirements. Idaho does not have a provision specifying where directors must reside.
  • Age requirements. Directors must be at least 18 years old.
  • Inclusion in the Articles of Incorporation. Director names and addresses are not required to be listed in the Articles of Incorporation.

Requirements for the Articles of Incorporation

The document required to form a corporation in Idaho is called the Articles of Incorporation. The information required in the formation document varies by state. Idaho's requirements include:

  • Officers. Officer names and addresses are not required to be listed in the Articles of Incorporation.
  • Stock. Authorized shares must be listed in the Articles of Incorporation. An increase in the number of shares does not affect initial filing fees.
  • Registered agent. Corporations must list the name and address of a registered agent with a physical address (no post office boxes) in Idaho. The registered agent must be available during normal business hours to accept important legal and tax documents for the business.

After forming a corporation, you must undertake certain steps on an ongoing basis to keep your business in compliance. These steps are also important in preserving the limited liability a corporation provides its owners. This guide outlines the ongoing requirements for Idaho corporations.
