Good to know

Idaho requires a monthly report for every month of the election year, each due the 10th of the following month (Idaho Code §67-6607). The published schedule prints the literal 10th even where it lands on a weekend (Jan 10, May 10, Oct 10, 2027 Jan 10) — file by the literal 10th. A single contribution of $1,000+ triggers a 48-hour report (event-driven, not listed here). $50/day late penalty.
