Who must file
The following committees must file the Maine Pre-Primary Report:
- Principal campaign committees of congressional candidates  (including unopposed candidates and candidates whose names do not appear on the ballot) who seek election in the primary election must file the above reports and notices. 
- PACs and party committees filing on a quarterly basis in 2020 are subject to pre-election reporting if they make previously undisclosed contributions or expenditures (including independent expenditures) in connection with an election by the close of books of the applicable report(s).
Before a committee can stop filing with the FEC, it must file a termination report with the Commission. Committees must continue to file reports until the Commission notifies them in writing that their termination report has been accepted.
 On 04/10/2020, the Maine Governor changed the congressional primary election from 06/09/2020 to 07/14/2020. The change was in response to the COVID-19 pandemic.
 These dates indicate the beginning and the end of the reporting period. A reporting period always begins the day after the closing date of the last report filed. If the committee is new and has not previously filed a report, the first report must cover all activity that occurred before the committee registered up through the close of books for the first report due.
 Generally, an individual becomes a candidate for federal office (and thus triggers registration and reporting obligations) when his or her campaign exceeds $5,000 in either contributions or expenditures. If the campaign has not crossed the $5,000 threshold, it is not required to file reports.
