FAQ

Do nonprofits need a separate bank account in Connecticut?

Yes. While not always legally required, a dedicated nonprofit bank account is essential for maintaining your tax-exempt status, satisfying donor expectations, and meeting Connecticut reporting requirements. Commingling personal and organizational funds can jeopardize your 501(c)(3) status.

Can a Connecticut nonprofit use a personal bank account?

Technically possible in early stages, but strongly discouraged. Connecticut's charitable solicitation requirements expect organizational funds to be held in a dedicated account. Most grantmakers and institutional donors require it.

What fees should Connecticut nonprofits watch for?

Monthly maintenance fees, minimum balance requirements, transaction limits, and wire transfer fees are the most common hidden costs. Holdings charges $0 for all of these. Traditional banks in Connecticut typically charge $10-30/month plus per-transaction fees after a limit.

How long does it take to open a nonprofit bank account in Connecticut?

With Holdings: same day (online application, no branch visit). With traditional banks: typically 1-2 weeks including branch appointments and document review.

Does a Connecticut nonprofit need 501(c)(3) status to open a bank account?

No. You can open a nonprofit bank account with your EIN and Articles of Incorporation before receiving your 501(c)(3) determination letter. Holdings and most banks allow this.
