Maddy summaryAB 24 requires Wisconsin county sheriffs to verify the immigration status of individuals jailed for felony offenses by requesting specific documentation (such as passports, birth records, or immigration documents) to confirm lawful presence in the U.S. If verification fails, sheriffs must notify federal Homeland Security and comply with federal detainer requests. Sheriffs must annually report compliance and maintain records of individuals found unlawfully present, with data shared with the state justice department. Counties failing to comply face a 15% reduction in state funding for the following year. The bill directly affects felony inmates, sheriffs, and state-local funding relationships.

Maddy summaryAB 39 requires most Wisconsin state employees to work at their agency's office for at least 80% of their regularly scheduled work hours each month. This applies to all state agencies, including departments and boards, but excludes employees whose duties were performed off-site before March 1, 2020, and staff from the investment board. The law mandates in-office work during standard hours, with exceptions for pre-pandemic remote work patterns. It takes effect on December 31, 2025, and does not apply to legislative or judicial staff.
Maddy summaryAB 326 creates a program providing grants to small local governments (populations under 7,500) to cover costs for grant writing and compliance assistance services. Grants up to $5,000 can be used for securing funding related to public works, transportation infrastructure, public safety, utility costs, or cybersecurity projects. The program requires a simple application listing only basic details (project purpose, contact info, and estimated costs) and prioritizes first-time applicants. A report evaluating the program must be submitted by December 2028.
Maddy summaryAB 308 prohibits Wisconsin state and local government funds from being used to pay for health services for individuals without legal immigration status. The bill directly affects undocumented residents by blocking state/local funding for their healthcare. Key provisions ban state/local funds for such services (except where federal law requires payment or where applying the ban would cause loss of federal funds). The law does not restrict federal healthcare programs or funding. This is a policy change affecting state budget allocations, not a procedural measure.
Maddy summaryAB 219 creates a 50% tax credit for eligible rail infrastructure spending in Wisconsin. It directly affects Class II/III railroads operating in the state and owners/lessees of rail sidings or industrial spurs, covering both new track construction (like spurs and sidings) and track maintenance (such as rail, ties, and safety systems). The credit applies to expenditures made after December 2024, with annual limits of $5,000 per mile of track owned and $2 million per project. Unused credits can be carried forward for up to five years, and credits may be transferred to other businesses subject to Wisconsin taxes.
Maddy summaryAB 984 sets new standards for community-based residential facilities that use the "memory care" designation in their name, advertising, or communications. It requires these facilities to serve only individuals with irreversible dementia (like Alzheimer’s) and to provide mandatory staff training on dementia care. The training must cover dementia basics, person-centered care, communication techniques, non-drug behavioral interventions, and supporting residents’ independence - both for initial hiring and annually thereafter. These requirements take effect July 1, 2027, with existing facilities needing compliance by that date to continue using the designation.
Maddy summaryAB 131 establishes a municipal grant program to test for PFAS (perfluoroalkyl and polyfluoroalkyl substances) in public water systems and fund source reduction measures. It allows water utilities to use customer service fees to cover up to half the cost of PFAS source reduction for connected customers, if cheaper than facility upgrades. The bill also creates eligibility rules for disadvantaged communities extending service due to PFAS contamination and directs PFAS contamination claims to an existing landowner grant program. These provisions directly affect municipal water systems, public utilities, and communities addressing PFAS in drinking water.
Maddy summaryAB 130 exempts specific groups from certain PFAS enforcement actions under Wisconsin's spills law if they allow the state to clean up contaminated land at no cost to them. It directly affects landowners, fire departments, airports, wastewater spreaders, and waste facilities that handled PFAS-contaminated materials legally. The bill creates exemptions for those who spread permitted biosolids, owned land where such spreading occurred, used PFAS in emergency response (per federal rules), accepted PFAS waste, or own property not responsible for the contamination origin. This applies only to enforcement sections related to PFAS contamination under the spills law, not all PFAS regulations.
Maddy summaryAB 751 modifies how electric utilities calculate fuel costs for their rate plans. It requires utilities to account for the cost of purchasing electricity and revenue from selling generation capacity that meets Midcontinent Independent System Operator (MISO) requirements when calculating fuel costs. This change affects electric utilities and their customers by adjusting how fuel cost differences (under- or over-collections) are handled in rate adjustments. The bill creates a new definition for "Midcontinent independent system operation" to align with existing MISO terminology.
Maddy summaryAB 685 allows Wisconsin taxpayers to subtract certain theft losses from their state income tax when those losses are already deductible under federal tax rules (specifically IRS Section 165(c)(2) or (3)). It directly affects individuals who experience qualifying theft losses, such as stolen property, that meet federal deduction criteria. The bill creates a new state tax subtraction provision (statute 71.05(6)(b)57) for these losses, while clarifying that taxpayers cannot claim both this subtraction and a separate casualty loss deduction for the same loss. This aligns Wisconsin's tax treatment with federal rules for theft-related deductions, without creating new federal standards.
