Good to know
The unconditional election-cycle C-4 summary reports for a full-reporting state legislative candidate. Also required but not listed here as fixed dates: monthly C-4 reports due the 10th of each month (next business day if a weekend/holiday) for any month with over roughly $750 of activity; weekly C-3 deposit reports each Monday from June 1; and an end-of-election-cycle C-4 covering December, due in mid-January 2027 (the PDC 2026 Key Dates page prints a wrong-year date for it — confirm on the 2027 schedule). Mini-reporting candidates are exempt from C-3/C-4 detail (deadlines to switch to full reporting are June 22 and August 31). File via ORCA; $1,500+ last-minute contributions trigger event-driven special reports.
