  • its name and address;
  • the names and addresses of all related or affiliated political or incidental committees*, and the nature of the affiliation;

Only candidates for state and local office and only political committees registered with the PDC must be listed. 
The C-1ic report is filed by delivering or mailing the completed form to the PDC office (PO Box 40908, Olympia, WA 98504).
If any of the information changes during the calendar year, the committee must file an amended C-1ic report within 10 business days. RCW 42.17A.207
*“Affiliated” or related committees are those that are established, financed, maintained or controlled by the organization designated as an incidental committee, or that are part of the same organizational structure of national, state and local bodies. Examples would be the organization’s own political committee, or a parent or branch organization that is itself an incidental committee. See WAC 390-16-309 for more details.
