Good to know
Minimal regime: a year-end report and a pre-primary and pre-general report, each due 15 days before the respective election (year-ends fall on the last Friday in January), all by 5:00 p.m. Central. The pre-primary applies to statewide candidates and, since a 2025 law change, legislative/county candidates on a contested primary ballot. A single large contribution/loan in a pre-election window triggers a 48-hour supplemental (event-driven, not listed here). South Dakota also holds primary runoffs (June 2026); a runoff candidate may owe a separate pre-runoff filing.
