An incidental committee that has no reportable activity in the month of December is automatically dissolved for PDC purposes only on Dec. 31, or upon filing its December C-8 report, whichever occurs later. (A committee may be required to file a C-8 by Jan. 10 of the following calendar year if it had a change in its top 10 sources of payments or it made an additional contribution to a candidate or political committee of more than $200 in December.) WAC 390-16-013
