Frequently asked questions about nonprofits in Connecticut

Answers compiled from the IRS Form 990, BMF, Pub 78, and Auto-Revocation List.

How many tax-exempt nonprofits are registered in Connecticut?
The IRS Exempt Organization Business Master File lists all currently-exempt organisations by state of address. Givalgo Discover provides a free profile for every IRS-registered nonprofit in Connecticut, sortable by sector, revenue, and IRS status.
Which sectors dominate connecticut nonprofit activity?
The IRS NTEE (National Taxonomy of Exempt Entities) classification breaks nonprofit activity into 26 major groups. Education, Human Services, and Health typically dominate by both count and aggregate revenue in most US states; the exact distribution for Connecticut is shown on this page.
How do I verify a connecticut nonprofit before issuing a grant?
Check the IRS Auto-Revocation List AND IRS Publication 78 — these are different feeds that answer different questions. Givalgo Discover cross-references both on every profile and surfaces a free due-diligence summary card.
Are donations to connecticut nonprofits tax-deductible?
Donations are tax-deductible only if the recipient is listed in IRS Publication 78 at the time of the gift. State-level registration with the Connecticut charities regulator is a separate requirement that does not affect federal deductibility.
Where can I find Form 990 financials for a connecticut nonprofit?
Form 990 is a federal IRS filing — financials, governance, and programs are public regardless of which state the nonprofit is registered in. Givalgo Discover aggregates the full Form 990 series for every IRS-registered organisation, including those in Connecticut.
