Good to know
Illinois committees file four quarterly D-2 reports per year (ISBE names them by quarter-end month: March/June/September/December). There is NO fixed-date pre-election report; near-election disclosure is the event-driven Schedule A-1 large-contribution report ($1,000+, due within 2 business days when received within 30 days of an election). Note: the statute (10 ILCS 5/9-10(b)) sets the December-quarter report due the 15th, but the ISBE 2026 calendar prints January 16, 2026 for it (internally inconsistent — it lists January 15, 2027 for the 2026 December quarter); we use the statutory, earlier-and-safer January 15 — reconcile with ISBE before relying on it.
Electbase compiles these dates from official state sources as a workflow aid. It is not legal advice. Confirm every deadline with your filing authority before you rely on it.
