Information you will need to file the Connecticut Certificate of Incorporation for nonprofit corporations

To become a nonprofit corporation in Connecticut you must file Form CIN-1-1.0, the certificate of incorporation for nonprofit corporations.

Here are the sections that you will need to complete.

Filing Party

Enter the name and address of the person who should receive confirmation of the filing.

Section 1: Name of Corporation

Enter the name you have selected.

For help with selecting a name for your nonprofit read our comprehensive guide on how to name a Connecticut nonprofit.

Section 2: Membership

Select the appropriate box depending on which statement accurately reflects your organization. If you select Option D, include an attachment that clearly explains how each class is designated.

Section 3: Registered Agent & Registered Office

The registered agent can be any entity registered to do business in Connecticut or any person who is a resident of the state. Your organization cannot act as its own registered agent.

Any person or business you designate as the registered agent must explicitly consent to act as the registered agent for your organization and verify their consent by signing Form CIN-1-1.0.

Enter the information of the registered agent in either Section A or B.

For more information read our guide: What is a registered agent? and The Connecticut Registered Agent Guide.

Section 4: Purpose

Describe the purpose of your nonprofit organization and additional provisions. Attach an additional sheet of paper if necessary.

In order to qualify for 501(c)(3) status, the organization’s purpose must explicitly be limited to one or more of the following:

  • Charitable
  • Religious
  • Scientific
  • Literary
  • Testing for public safety
  • Fostering national/international amateur sports competition
  • Preventing cruelty to animals/children

NOTE: You can read the IRS guidelines on their website.

Section 5: Other Information

Use this section of the articles of formation to formally state what the assets of the organization will be used for, and what will happen to the assets if the organization is dissolved.

To be eligible for 501(c)(3) status, you must convince the IRS that the organization’s assets will always only be used for the purposes approved under 501(c)(3) rules. To this end, you must include provisions ensuring that in the event your organization is dissolved, the assets of the organization will be used towards tax-exempt purposes.

Section 5 of this sample document provides an example of these provisions required for 501(c)(3) eligibility.

Section 6: Corporation Email Address

Provide an email address for your nonprofit. This email will be used to send you a reminder to file your Annual Report. If your nonprofit does not have an email address, write NONE on the form.

Section 7: Execution

When the incorporators sign and date the form they are affirming everything written in the form. They are also affirming that the registered agent listed has already consented to be the registered agent for this nonprofit organization.

The incorporators are the people who complete, sign, and submit the Articles of Incorporation. These people do not need to be a part of your organization.
