Starting a nonprofit in Illinois

Everything below is generated from the same Illinois rules dataset that powers your guided journey in the platform — filing forms, real fees, and the traps DIY templates fall into.

Incorporation

Filing
Form NFP 102.10 — Articles of Incorporation, General Not For Profit Corporation Act
Agency
Illinois Secretary of State, Department of Business Services
State fee
$50 — never marked up by us
Processing
About 5–10 business days online; several weeks by mail
Expedite
$25 expedited (24-hour, in person at Springfield or Chicago)
Watch out
  • Form NFP 102.10's purpose checkboxes do NOT satisfy the IRS — the required 501(c)(3) purpose and dissolution clauses must be added in the 'other provisions' article or the IRS will reject your exemption application.
  • Illinois requires at least 3 directors.
  • Paper filings must be submitted in duplicate and paid by certified check or money order — one more reason to file online.

Ongoing compliance

Registered agent
Must have an Illinois street address; the corporation cannot serve as its own agent.
Charitable registration
Required — Illinois Attorney General, Charitable Trust Bureau (Form CO-1). Initial: $15. Renewal: Annual — Form AG990-IL with a $15 fee, due 6 months after fiscal year end. Illinois requires registration before soliciting OR holding charitable assets — broader than most states. Small-organization exemptions exist but are narrow.
Annual report
Annually, before the first day of the anniversary month — $10
State tax exemption
Apply to the Illinois Department of Revenue for a sales tax exemption 'E number' (submit articles, bylaws, and the IRS letter). Income tax exemption follows the IRS determination.
