Rep. Dave Prestin

Maddy summaryThis bill designates the black swallowtail butterfly (*Papilio polyxenes*) as Michigan's official state butterfly. It creates a symbolic, non-regulatory change by formally naming this specific species in state law. The bill has no financial, regulatory, or operational provisions - it solely establishes a ceremonial designation. The change would take effect 90 days after enactment. This is a procedural resolution with no direct impact on policies, programs, or specific groups.

Maddy summaryHB 4185 changes how Michigan's general sales tax revenue is distributed. It directs 15% of the 4% sales tax to cities, villages, and townships through the Glenn Steil Revenue Sharing Act. Sixty percent goes to the state school aid fund (including all 2% tax from aviation fuel sales), while 27.9% of 25% from vehicle/fuel sales funds the transportation system. Additionally, it requires $9-12 million annually from computer software sales to the Michigan health initiative fund.

Maddy summaryHB 4184 increases Michigan's excise tax on aviation fuel from 3.10 cents to 4.00 cents per gallon. It directly affects fuel sellers, airlines, and airport operators by changing how this tax revenue is distributed. The bill modifies Section 203 of the Aeronautics Code to require 35% of the tax revenue to fund the state aeronautics fund and 65% to fund qualified airports. It also retains the 1.5-cent refund for airlines operating interstate flights and the exemption for fuel used in leaded racing fuel production.

Maddy summaryHB 4186 increases Michigan's business income tax rate from 4.95% to 30% for all business activity occurring on or after January 1, 2025. This rate change directly affects businesses operating within Michigan that are subject to the state's business tax, including those previously filing under the corporate income tax act. The bill amends sections 201 and 500 of the Michigan Business Tax Act (2007 PA 36) to implement this rate increase and adjust the tax base calculations for businesses. The change represents a significant policy shift in how Michigan taxes business income, effective in 2025.

Maddy summaryHB 4170 permanently sets Michigan's individual income tax rate at 4.05% for all taxpayers, replacing a temporary 4.25% rate scheduled to take effect in 2024. It creates a mechanism where the rate could decrease further if state revenue growth exceeds inflation, requiring annual revenue reviews. The bill directly affects all Michigan residents who pay individual income tax. The change takes effect immediately for tax years beginning January 1, 2025, with the 4.05% rate now permanent unless triggered by the revenue growth condition.

Maddy summaryHB 4237 prohibits Michigan local governments (like cities, counties, and school districts) from awarding or renewing contracts that give contractors access to personal data if the contractor is a "controlled entity" tied to specific foreign countries of concern (China, Russia, Iran, North Korea, Cuba, Venezuela, or Syria). It requires contractors to submit sworn affidavits confirming they are not controlled entities, with violations subject to fines up to twice the contract value or a 5-year contract ban. The bill also restricts local governments from using information technology or services designed, developed, or supplied by companies owned by those foreign countries, aligning with federal security lists. These rules take effect July 1, 2026, for contract renewals and extensions.

Maddy summaryHB 4032 permanently extends Michigan's participation in the Interstate Medical Licensure Compact by removing a scheduled expiration date (sunset) from the law. This change directly affects physicians in Michigan who use the compact to practice medicine across state lines, as it eliminates the need for periodic legislative renewal. The bill's key provision amends Michigan's Public Health Code to make the compact's terms permanent, ensuring uninterrupted eligibility for physicians seeking multi-state licensure. The compact allows doctors to obtain licenses in multiple participating states more efficiently, reducing administrative barriers for cross-state medical practice.

Maddy summaryHB 4176 amends Michigan's Natural Resources and Environmental Protection Act (MCL 324.73102) to allow property owners to use purple paint marks as a legal alternative to posted signs for marking "no trespassing" areas. Specifically, it requires purple paint marks to be vertical lines 8 inches long, placed 3-5 feet high on trees or posts, spaced no more than 100 feet apart, and visible from all approaches. This change directly affects property owners who can now use this method to legally prohibit recreational activities or trapping on their land without physical signs. The bill does not alter existing exceptions for farm property, fishing, or retrieving lost dogs, and it requires companion bill HB 4177 to also pass for full implementation.

Maddy summaryHB 4177 amends Michigan's Natural Resources and Environmental Protection Act to strengthen rules about purple paint marks used to indicate no-trespassing areas for recreation. It prohibits removing, defacing, or destroying existing purple paint marks (Sec. 73104) and bans placing new marks on others' property without written permission from the owner, lessee, or agent (Sec. 73105). The bill directly affects property owners, recreational users (like hunters or anglers), and land managers who use these marks to restrict access. It creates a clear legal requirement for written authorization before marking private property, ensuring property rights are respected during recreational activities.

Maddy summaryHB 4188 amends Michigan's Vehicle Code to clarify that operating a vehicle "in a careless or negligent manner likely to endanger any person or property, but without wantonness or recklessness" would be classified as a civil infraction. This change directly affects drivers whose behavior meets this specific standard - non-reckless, careless driving - by treating it as a civil matter rather than a criminal offense. The bill modifies Section 626b of the Michigan Vehicle Code (MCL 257.626b) to explicitly exclude cases involving "wantonness or recklessness," which would remain subject to more severe penalties. The amendment is procedural and aims to refine the legal definition of the infraction. The bill was introduced on March 6, 2025, and referred to the Judiciary Committee.
