Campaign finance: public disclosure; certain political nonprofit organizations; define. Amends secs. 2 & 5 of 1976 PA 388 (MCL 169.202 & 169.205). TIE BAR WITH: HB 4269'25

HB 4270 amends Michigan's Campaign Finance Act to clarify disclosure requirements for certain political nonprofits. It redefines "501(c)(4)" and "527" organizations to include those controlled by state candidates, elected officials, appointed officials, or their family members. These nonprofits would then be required to disclose their funding sources and activities, directly affecting organizations with ties to Michigan's political figures. The bill takes effect January 1, 2027, pending passage of companion legislation (HB 4269).
