Committees that have received contributions or made expenditures of $100,000 or more during the 2020 presidential election cycle must file monthly reports.
48-Hour Notices of contributions 
Notices are required if the committee receives any contribution (including in-kind gifts or advances of goods or services; loans from the candidate or other non-bank sources; and guarantees or endorsements of bank loans to the candidate or committee) of $1,000 or more per source, during the period less than 20 days but more than 48 hours before any election in which the candidate is running.
The notices must reach the appropriate federal filing office within 48 hours of the committee’s receipt of the contribution(s). Campaign committees that file electronically MUST submit their 48-Hour Notices electronically. Candidates faxing 48-Hour Notices should transmit them to the FEC at 202-219-0174.
 Presidential primary campaigns filing monthly need not file 48-Hour Notices.
