HB 5496 imposes a 32% excise tax on the purchase price of wireless communications devices (like smartphones) sold primarily for use by individuals under 18 years old, effective January 1, 2026. The tax is collected at the point of sale by retailers, similar to other state taxes, and applies only to devices that support internet, apps, or multimedia - excluding basic telephones. All tax revenue flows into a new "Children's Mental Health and Safety Fund" in the state treasury, which must be used exclusively for mental health and safety programs for children as defined by existing law. The fund’s money remains available annually and cannot be redirected to the general state budget.
HB 5395 modifies Michigan's Brownfield Redevelopment Financing Act to update tax credit rules for cleaning and redeveloping contaminated properties. The bill revises definitions of "blighted" property (including previously developed land and land bank properties) and clarifies how tax revenue captured during redevelopment - specifically construction-phase income taxes on wages - will be calculated and reinvested. Local authorities, developers, and municipalities working on brownfield sites will directly use these revised rules for tax increment financing. The changes aim to streamline financing for projects that clean up environmental hazards while redeveloping underutilized land.
HB 5286 establishes a formal brownfield redevelopment grant and revolving loan program under Michigan's environmental law. The program provides funding to local governments (counties, cities, townships) for eligible cleanup and redevelopment activities at contaminated properties, including environmental assessments, site remediation, and demolition. Projects must demonstrate measurable economic benefits (like job creation or tax revenue) and environmental benefits (advancing cleanup standards), with grants/loans capped at $2 million per project. Applicants must prove financial capability, show compliance with environmental laws, and avoid being responsible for the site's contamination. The program draws from existing funds like the Clean Michigan Initiative Bond Fund and the State Brownfield Redevelopment Fund.
HB 4143 changes how Michigan allocates corporate income tax revenue. Starting in the 2025-2026 fiscal year, it directs $500 million annually to county road commissions and $500 million to cities/villages for local road projects. After 2026, all corporate tax revenue from this source will fund the Michigan Transportation Fund, which distributes money for state transportation projects. This directly affects local governments receiving road funding and state budget allocations for transportation infrastructure.
HB 4952 amends Michigan's Use Tax Act to change how 2% tax revenue from aviation fuel is distributed. It directs 35% of this tax to the state aeronautics fund and 65% to the qualified airport fund for airport-related expenses. The bill also mandates annual deposits into the local government reimbursement fund: $75 million starting fiscal year 2024-25, then $25 million annually after 2025-26. These changes affect schools (through school aid fund provisions), airports (via fund allocations), and local governments (receiving reimbursements).
HB 5099 modifies how funds in Michigan's convention facility development fund are distributed. It directs specific annual payments to metropolitan authorities operating convention facilities (including $7 million for 2020-2021 due to COVID-19 impacts), establishes a formula for distributing liquor tax revenue to counties based on convention hotel presence, and allocates up to $4 million for one-time grants to publicly owned convention centers negatively affected by the pandemic. The bill also specifies funding for street railway operations and sets reporting requirements for grant recipients. These changes affect convention facilities, local governments, and tourism-related infrastructure funded through this dedicated tax revenue stream.
HB 4951 creates a new tax on marijuana sales to fund state road infrastructure projects. It directly affects marijuana businesses (which pay the tax) and state transportation budgets (which receive the revenue). The key mechanism establishes a dedicated funding stream, redirecting tax revenue from cannabis sales toward repairing and maintaining roads, rather than general state funds. The bill became law immediately upon the Governor's approval on October 7, 2025.
House Bill 4342 amends Michigan's state revenue sharing act, introducing a new condition for withholding state funds from local governments. Beginning October 1, 2025, the state treasurer would withhold all revenue sharing payments from any city, village, township, or county. This would occur if the local government enacts or enforces a law, ordinance, policy, or rule that violates the "local government sanctuary policy prohibition act" or the "county law enforcement protection act." Payments would be withheld for as long as the violating policy remains in effect. This bill is tied to the enactment of House Bills 4338 and 4339.
HB 4121 prohibits local governments (counties, cities, townships, villages) from adopting property tax caps that automatically reduce tax rates when revenue hits a fixed dollar limit. It voids any existing local tax cap with this automatic reduction feature and requires local units to disregard such caps. The bill specifically targets caps imposed by local charter, ordinance, or policy - not state-mandated limits - making them unenforceable. This change ensures local tax revenue limits cannot trigger automatic rate cuts based solely on annual dollar amounts.
HB 4144 increases Michigan's corporate income tax rate from 6% to 8.5% effective January 1, 2025, affecting corporations operating in the state. It directs a specific portion of the revenue increase - specifically, the amount attributable to the 2.5% rate hike - to the state school aid fund starting with the 2025-2026 fiscal year. The bill also allocates other portions of the tax revenue to housing, community development, and revitalization funds during the 2022-2025 fiscal years. This is a direct policy change altering tax rates and revenue distribution, not a procedural or commemorative measure.
