Primary SB 284
Failed · Wisconsin Senate · Lead sponsor
Relating to: a sustainable aviation fuel production tax credit. (FE)

Maddy summarySB 284 defines key terms for a future sustainable aviation fuel (SAF) tax credit program. It specifies that "renewable biomass" includes wood waste, crop residues, dairy byproducts, and other organic agricultural waste, and defines "sustainable aviation fuel" as aviation fuel derived from this biomass and meeting U.S. Department of Energy standards. The bill replaces outdated terms like "energy crops" with "renewable biomass" throughout the tax credit framework. This definitional bill enables future tax credits for SAF producers but does not establish the credit amount or implementation details. (Note: The bill is still pending scheduling as of the latest action on 2025-11-06.)

Relating to: an agricultural purchase program and making an appropriation. (FE)

The program provides grants to nonprofit food banks, pantries, and local food distributors to buy food produced within the state. It establishes new staff positions (a program specialist and grants specialist) within the Department of Agriculture to manage the program, funded by the same appropriation. The bill directly affects Wisconsin food assistance providers and local agricultural producers by creating a dedicated funding stream for regional food purchases.

Primary SB 592
Failed · Wisconsin Senate · Lead sponsor
Relating to: excluding certain event or sports wagers from the definition of “bet”.

Maddy summarySB 592 modifies state law to exclude certain event or sports wagers from the legal definition of "bet." Specifically, it exempts wagers made by people physically in the state using mobile devices if the wagering server is on tribal lands and the activity follows an Indian gaming compact signed before April 1, 1993. This primarily affects tribal gaming operations that conduct mobile sports betting under these specific historical agreements. The change clarifies that such wagers are not treated as "bets" under current gambling statutes.

Primary SB 660
Failed · Wisconsin Senate · Lead sponsor
Relating to: a public information campaign related to aggressive driving and making an appropriation. (FE)

Maddy summarySB 660 creates a statewide public information campaign to reduce aggressive driving behaviors like excessive speeding, illegal racing, and fleeing police. The campaign, funded with $500,000 over two fiscal years, must run for 1-2 years and prioritize local governments with the highest rates of these incidents. It requires using billboards, radio, TV, and digital ads, while partnering with local creative agencies and community groups (like schools and churches) to share real stories from affected drivers and families. The law mandates that materials reflect the experiences of high-risk drivers and target communities most impacted by aggressive driving.

Facilities must report annually on the number of animals they owned, used for testing, and transferred to adoption groups. Violations could result in fines up to $5,000 per animal. This bill directly affects facilities and breeders that handle dogs or cats for research, education, or breeding purposes.

Primary SB 171
Failed · Wisconsin Senate · Lead sponsor
Relating to: requiring child sexual abuse prevention education. (FE)

Maddy summarySB 171 requires all public school districts to implement age-appropriate child sexual abuse prevention education for students in 4-year-old kindergarten through 12th grade starting in the 2026-2027 school year. The law mandates specific curriculum content, including anatomical terms, setting personal boundaries, identifying safe/unsafe touch, recognizing abuse signs, and reporting procedures. Schools must provide parents with program outlines, timing details, and educational materials about abuse prevention and vulnerability factors before instruction begins. Parents may opt their child out of the program with a written request, but schools must still share the educational resources with them.

Primary SB 341
Failed · Wisconsin Senate · Lead sponsor
Relating to: the timing of equalization aid payments to school districts. (FE)

Maddy summarySB 341 changes how Wisconsin school districts receive state funding for the 2024-2030 school years. It gradually increases the percentage of annual aid paid in September (from 15% to 25%) while decreasing the June payment (from 35% to 25%), with fixed 25% payments in December and March each year. This affects all Wisconsin school districts that receive state equalization aid. The bill does not change the total annual funding amount, only the timing of payments.
