How to Open a Nonprofit Bank Account in Illinois

What You Need to Know

Illinois is home to approximately 70,000 registered nonprofits, with the vast majority concentrated in the Chicago metropolitan area. The state's nonprofit sector is the sixth-largest in the nation, spanning social services, education, healthcare, arts and culture, and community development. Chicago alone hosts more than 30,000 nonprofit organizations.

Beyond Chicago, nonprofit hubs include Springfield, Champaign-Urbana, Peoria, and Rockford. Illinois's nonprofit sector employs over 600,000 people and generates more than $80 billion in annual revenue. The state's diverse economy and large population base create significant demand for nonprofit services across every sector.

Illinois has a moderate regulatory framework for nonprofits. Filing fees are $50 for incorporation — reasonable compared to many states. The Attorney General's office oversees charitable solicitation, and the annual AG990-IL filing is the primary ongoing compliance requirement. With 765 FDIC-insured institutions and Chase's home market presence, Illinois nonprofits have excellent banking options.

Illinois Nonprofit Registration Requirements

1. Incorporate with the Illinois Secretary of State

File Articles of Incorporation (nonprofit) with the Illinois Secretary of State. The filing fee is $50. File through the Illinois Secretary of State — Nonprofit Filing. Illinois requires specific language regarding purpose, dissolution, and non-distribution of assets.

2. Get Your Federal EIN

Apply for an Employer Identification Number (EIN) from the IRS — free, takes minutes online at IRS EIN application.

4. Register for Illinois Tax Exemption

FAQ

Do nonprofits need a separate bank account in Illinois?

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

Can an Illinois nonprofit use a personal bank account?

Technically possible in early stages, but strongly discouraged. Illinois's AG990-IL filing requirements expect organizational funds to be held in a dedicated account. Most grantmakers and institutional donors require it.

What fees should Illinois 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 Illinois typically charge $10-15/month plus per-transaction fees after a limit.

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

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

Does an Illinois 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.

How high are sales taxes in Illinois?

Illinois has a 6.25% state sales tax plus local additions that can push the combined rate to 11% in some areas (notably in Chicago). This makes the 501(c)(3) sales tax exemption particularly valuable for Illinois nonprofits making significant purchases.
