Good to know
Election-cycle C&E reports for the 2026 cycle (June 16 primary / August 25 runoff / November 3 general). Each due date is the LAST day of Oklahoma's filing window. The pre-runoff report applies only to candidates in the August 25 runoff. Outside the election cycle, committees file plain quarterly reports. Continuing Reports of Contributions (over $1,000 within 24 hours) and the Statement of Organization are event-driven and not listed here. The Guardian system also assigns each committee a personalized schedule — confirm there.
