The Small Dollar Donor Protection Act requires federal candidate committees to report aggregate information about small donations they receive from contributors who give less than $200 per election cycle. Currently, campaigns do not have to disclose who donates below the $200 threshold, so this bill would create transparency by requiring committees to report the total amount and number of such contributions received. The Federal Election Commission must issue guidance within 90 days to help campaigns comply with the new reporting requirements, which take effect immediately for most committees and within two reports for those that filed during the 90-day period before the law's enactment. Additionally, the bill directs the Federal Election Commission to study how candidate committees solicit these small donations and investigate whether deceptive or fraudulent methods are being used, with a report to Congress due within 180 days that includes recommendations to prevent such practices. The legislation aims to increase transparency in small-dollar fundraising while protecting donors from potential abuse.
