How to Start a Nonprofit in Connecticut
Connecticut uses distinctive terminology—calling nonprofits "nonstock corporations"—and has generally straightforward formation requirements. The state offers sales tax exemption for nonprofits (unlike Alabama, Arizona, California, and Georgia), automatic state income tax exemption, and standard charitable solicitation registration.
Formation Requirements
Connecticut has a clean, efficient nonprofit formation process. You'll file a Certificate of Incorporation with Connecticut's Secretary of the State.
The process:
- Prepare your Certificate of Incorporation (Nonstock Corporation form)
- File online ($50), in-person ($50), or by mail ($50)
- Standard processing: 5-7 business days
- Expedited processing: $50 additional (approximately 1 business day)
- Receive your Certificate of Incorporation
Filing costs:
- Certificate of Incorporation: $50
- Name reservation (optional): $60
- Total: $50-$110 for formation
Connecticut requires a minimum of 3 directors. You must also designate a registered agent with a Connecticut address.
Important: The "Nonstock Corporation" Terminology
Connecticut calls nonprofits "nonstock corporations." This is simply terminology—it means the corporation doesn't issue stock. The legal effect is identical to "nonprofit" in other states. Don't let the term confuse you. Your formation document will say "nonstock corporation," and that's correct.
Governance Requirements
Connecticut requires a minimum of 3 directors. Required officers are President, Secretary, and Treasurer.
You must adopt bylaws (not filed with the state). Bylaws should address meeting procedures, director and officer provisions, committees, and your fiscal year.
You need a registered agent with a Connecticut address. The agent can be an individual or business entity authorized in Connecticut. Change of agent fee is not specified in available sources—contact the Secretary of the State for current rates.
Tax Exemption
State Income Tax: Good news—it's automatic. Connecticut's Corporation Business Tax exemption is automatic once you receive your federal 501(c)(3) determination letter. No separate state application needed.
Sales Tax: Connecticut provides sales tax exemption for qualifying 501(c)(3) organizations. This is one of the benefits of incorporating in Connecticut versus several other states.
File Form REG-1 (Application for Tax Registration Number) with the Connecticut Department of Revenue Services. Check the box for nonprofit exempt status. Once approved, you'll receive an Exempt Purchaser Certificate (CERT-119). Use this certificate when making purchases to certify that the transaction is exempt.
Property Tax: Nonprofit property tax exemptions are available at the municipal level. Apply to your Town Assessor's office. Property must be used exclusively for exempt purposes.
Ongoing Compliance
Annual Report: Connecticut requires an annual report on the anniversary of your incorporation, every year. Fee is $50. File online at business.ct.gov. Late filing can result in additional fees and may affect your good standing. This is one of the higher annual report fees among states for nonprofits.
Charitable Solicitation Renewal: Due annually. Fee is $50. File online through the Department of Consumer Protection portal. If your organization's gross revenue exceeds $500,000, you must submit audited financial statements with your registration.
Federal Form 990: Due the 15th of the 5th month after your fiscal year end (typically May 15). File with the IRS. No state return needed.
Charitable Solicitation
Connecticut requires registration before you solicit contributions.
Exemptions:
- Organizations receiving less than $50,000 in contributions annually with no compensated solicitors
- Religious organizations
- Educational institutions
Exempt organizations should still verify their status with the DCP.
Registration and Renewal:
File online with the Department of Consumer Protection. Initial registration fee is $50. Annual renewal also costs $50. If your organization's gross revenue exceeds $500,000, you must submit audited financial statements with your renewal.
Key Deadlines
- Formation filing: 5-7 business days (standard) or 1 business day (expedited)
- Sales tax exemption registration: No specific deadline, but register soon to start using exemption
- Annual report: Anniversary of incorporation each year (firm deadline)
- Charitable solicitation renewal: Annually (due date tied to your fiscal year)
- Federal Form 990: 15th of 5th month after fiscal year end
Important Considerations
"Nonstock" is Correct Terminology: Connecticut's use of "nonstock corporation" is accurate and standard terminology within Connecticut law. Don't try to change it to "nonprofit"—the state's documents will use "nonstock."
Sales Tax Exemption Available: This is genuinely helpful. Connecticut does provide a general sales tax exemption for nonprofits (apply with Form REG-1). You'll use your Exempt Purchaser Certificate (CERT-119) for tax-free purchases.
$50 Annual Report Fee is on the Higher End: Many states charge $25 or less. Connecticut's $50 annual report is on the higher side. Budget for this recurring cost.
$50,000 Threshold for Charitable Solicitation: Connecticut's exemption threshold ($50,000 in contributions) is higher than the typical $25,000 in many states. This means more small organizations can avoid registration.
Audited Financials at $500,000: Organizations with gross revenue exceeding $500,000 must submit audited financial statements with their charitable solicitation registration. This is a significant compliance cost for mid-size nonprofits.
Automatic State Income Tax Exemption: No separate application needed. Federal 501(c)(3) status automatically confers Connecticut income tax exemption.
