Good to know
This is Schedule B — committees of fall partisan candidates on the 2026 ballot. Pre-primary and pre-election reports may be filed starting 14 days before the election; the date shown is the final deadline (8 days before). Deadlines falling on a non-business day move to the next business day.
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.
