HB 4376 modifies Michigan's sales tax rules for trade-in values on vehicle purchases. It increases the annual adjustment for the maximum deductible trade-in value from $500 to $1,000, starting January 1, 2020. This change allows car buyers trading in vehicles to reduce the taxable sales price by more when purchasing new or used cars from dealers. The provision applies only when the trade-in value is separately stated on the sales invoice.
HB 4747 adds a new state income tax deduction for Michigan taxpayers who contribute to 529 education savings plans. It allows residents to subtract their 529 plan contributions from their taxable income when filing Michigan state taxes, directly benefiting families saving for education costs. The bill amends Michigan’s tax code to create this specific deduction, effective immediately after its passage on October 23, 2025. This change provides a direct financial incentive for contributing to qualified education savings accounts.
SB 565 amends Michigan's property tax reimbursement fund rules to require that unused funds from the local government reimbursement fund lapse (transfer) to the state's general fund at year-end, instead of remaining in the fund. It directly affects municipalities that receive state reimbursements for revenue lost due to small business property tax exemptions under the General Property Tax Act. The key change modifies Section 3a of the Michigan Trust Fund Act (2000 PA 489) to ensure unspent funds are returned to the state's general budget annually, rather than carrying over. This is a procedural adjustment to fund management, not a change to tax exemptions or reimbursement eligibility.
SB 166 allocates funding for K-12 public schools in the state for the 2025-2026 fiscal year. It directly affects all public K-12 school districts by providing their state education budget. The bill establishes the specific financial amounts schools will receive during this fiscal period. It became law on October 7, 2025, with immediate effect (PA 0015'25).
HB 4181 removes a sales tax exemption for certain motor fuel purchases by amending Michigan's 2004 tax code (MCL 205.173 & 205.175). The bill directly affects businesses and consumers purchasing motor fuel by eliminating an existing tax exemption, meaning these purchases will now be subject to sales tax. It streamlines the tax code by clarifying that motor fuel is no longer exempt from sales tax under the specified sections. The bill was enacted on October 7, 2025, and is now law as Public Act 18 of 2025.
SB 578 creates a new Neighborhood Roads Fund to support maintenance of local neighborhood streets and modifies the existing Movable Bridge Fund to improve bridge infrastructure funding. The bill changes how these funds are managed and allocated, directly affecting local governments responsible for road and bridge upkeep. Key provisions include establishing dedicated funding sources for neighborhood roads and adjusting eligibility rules for bridge repair projects. These changes clarify state funding streams for community infrastructure without altering tax rates or new construction policies.
HB 4183 increases the motor fuel tax rate and expands the types of fuels subject to the tax under Michigan law. It directly affects motor fuel sellers (like gas stations) and consumers through higher costs for gasoline and other taxed fuels. The bill amends Section 8 of the 2000 Motor Fuel Tax Act (MCL 207.1008) to implement these changes, which became law immediately upon approval by the Governor on October 7, 2025.
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.
This constitutional amendment (HJR M) would require Michigan's general budget bills to be enacted by a specific date each year (currently set as August 1st under existing law). If not enacted by that date, it would suspend the pay of all state legislators and the governor until the budget is passed. The bill amends Articles IV, V, and IX of the Michigan Constitution to establish this deadline and consequence. It is not yet law, as it failed to pass during its August 21, 2025, vote (70 yeas, 30 nays).
HB 4580 allocates funding for Michigan's public universities during the 2025-2026 fiscal year. It amends specific sections of Michigan law (MCL 388.1836 and 388.1841) to establish the budget for higher education institutions. The bill directly affects public universities by providing their state funding for the upcoming fiscal year. It passed the House with strong support (56-41) and is now moving to the appropriations committee for further review.
