Committees have a C-4 or C-6 due by January 31, 2021. The campaign finance report covers all transactions, if any, that occur from November 26th through December 31, 2020. Incidental political committees use Form C-4 (C-4 guide) to report financial activities; all other committees (political party, ballot issue, and independent (PAC) committees) use Form C-6 (C-6 guide) to detail all contributions received and expenditures made during a specific timeframe. C-4s and C-6s must be filed in CERS.
An incidental committee is a political committee which is not organized or maintained for the primary purpose of influencing elections but which may incidentally become a political committee by reason of making a contribution or expenditure to support or oppose a candidate and/or issue (Administrative Rules of Montana 44.10.327(2)(c)).
Each county, municipal, and school district committee is required to file campaign finance reports if contributions received or expenditures made exceed $500 (in total).
After November 2019, all committees will file campaign finance reports on the same date and for the same time period.
