. Monthly filers are reminded they have a report due Saturday, September 20, covering the month of August. Please note that the FEC does not have authority to extend filing deadlines, even when they fall on weekends or holidays. Filers should plan accordingly. Monthly reports sent by registered, certified or overnight mail must be postmarked no later than September 20, and paper filings sent by other means must be received by close of business on the last business day before the deadline (i.e., Friday, September 19). Electronic filers have until 11:59 p.m. (EDT) on the due date of the report to submit their reports on time. Quarterly filers do not have a regularly scheduled report due this month, but if they have made contributions or expenditures in connection with ongoing special elections or regular primary elections, they may have to file additional reports. Quarterly filers should refer to the FEC's compliance map to determine if an additional report is required.
