Senate Bill 126 amends the effective date of certain provisions from 2023 Wisconsin Act 126, which addresses various aspects of campaigns and elections. The bill specifically changes the effective date for filings with the Ethics Commission through the campaign finance information system (CFIS) from July 1, 2025, to December 1, 2027. All other provisions of Act 126, which include prohibiting public access to certain election officials' personal information, establishing penalties for harming election officials, and providing whistleblower protections, will still take effect on the original date of July 1, 2025.

The bill includes a renumbering and amendment of section 35 of Act 126, which now specifies that the act will take effect on July 1, 2025, with the exception of the provisions related to the Ethics Commission filings, which will take effect on December 1, 2027. Additionally, a new section (35 (1m)) is created to outline the specific provisions that will have the delayed effective date.
