Supplemental filing information for congressional committees (2023)
Please note: The Commission provides reminders of upcoming filing dates as a courtesy to help committees comply with the filing deadlines set forth in the Act and Commission regulations. Committee treasurers must comply with all applicable filing deadlines established by law, and the lack of prior notice does not constitute an excuse for failing to comply with any filing deadline.
Who must file
Principal campaign committees of congressional candidates  (including unopposed candidates and candidates whose names do not appear on the ballot) must file quarterly reports in 2023. 
NOTE: If a candidate has more than one authorized committee, the principal campaign committee files a consolidated report on Form 3Z in addition to filing the report on Form 3.
Campaigns that trigger the registration and reporting requirements must file quarterly reports until the committee is terminated, even if the candidate plans to retire, withdraws from the race prior to the primary election, loses the primary, or drops out the race prior to the general election. A committee may terminate after it has filed a termination report with the Commission and the Commission notifies them in writing that their termination has been accepted.
Methods of filing reports
Reports filed electronically must be received and validated by the Commission by 11:59 p.m. Eastern Time on the filing deadline.
For committees not required to file electronically, paper reports filed using registered, certified or overnight  mail must be postmarked by 11:59 p.m. Eastern Time on the filing deadline. Paper reports filed using first class mail must be received by the FEC by the close of business on the filing deadline.
Committee treasurers are responsible for both the timeliness and the accuracy of all reports. They may be subject to monetary penalties if reports are inaccurate or are not filed on time.
Administrative Fine Program
Under the Administrative Fine Program, political committees and their treasurers who fail to file their reports, or who file late, may be subject to civil money penalties up to $25,434 (or more for repeat late- and non-filers). 
Disclosure of lobbyist bundling activity
Principal campaign committees must file Form 3L if they receive two or more bundled contributions from any lobbyist/registrant or lobbyist/registrant PACs that aggregate in excess of $21,800 during the applicable reporting periods. Learn more about the lobbyist bundling disclosure requirements.
Access the Form 3L PDF and instructions.
 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 received or expenditures made. If the campaign has not crossed the $5,000 threshold, it is not required to file reports.
 If a candidate has more than one authorized committee, the principal campaign committee files a consolidated report on Form 3Z in addition to filing on Form 3.
 "Overnight mail" includes Priority or Priority Express Mail having a delivery confirmation, or an overnight service with which the report is scheduled for next business day delivery and is recorded in the service's online tracking system. Note that "Express Mail" as referred to in FEC regulations has been renamed "Priority Express Mail" by the USPS.
 Penalties for late- and non-filing of 48-Hour Notices are based on the amount of contributions received that are not timely disclosed. As a result, these penalties may exceed $25,434, even for first-time violations.
