Good to know
The standard NON-CEP schedule — for candidates NOT participating in Connecticut's Citizens' Election Program (public financing). CEP participants instead file weekly supplemental reports (First/Second/Final) around each election. The four quarterly filings (Jan 10 / Apr 10 / Jul 10 / Oct 10) are required of every open committee; the pre-primary and post-primary reports apply only to candidates in a primary. Some coverage-start dates vary by CEP participation and primary status. Weekend/holiday shifts are already applied. Conditional deficit/termination reports are not listed here.
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.
