How do I vet a mutual benefit nonprofit in Connecticut before donating?

Are donations to Connecticut mutual benefit nonprofits tax-deductible?
Federal deductibility is determined by IRS Publication 78 status, not state location. Donations to a Pub 78-listed mutual benefit nonprofit in Connecticut are tax-deductible at the federal level; Connecticut state tax treatment may differ.
Where do mutual benefit nonprofits in Connecticut file their Form 990?
All US tax-exempt organisations file Form 990 with the IRS at the federal level — there is no state-specific filing for the federal exemption itself. Connecticut state charity registration is a separate state-level requirement.
