SB 561 amends Michigan's sales tax law to change how revenue is distributed. It allocates 8.6% of the 4% general sales tax (starting October 1, 2025) to a new Revenue Sharing Trust Fund for distribution to cities, villages, townships, and counties. The bill also directs computer software sales tax revenue ($9-12 million annually) to the Michigan Health Initiative Fund and splits aviation fuel tax revenue (35% to the state aeronautics fund, 65% to airport funds). These changes affect local governments, public schools (via school aid fund allocations), airports, and health programs, without altering the overall tax rates.
SB 573 modifies Michigan's corporate income tax law to change how tax revenue is distributed. It revises Section 51 of the tax code, adds new Sections 51a and 695a, and removes several existing sections (51d-f, 51h, 476, 695). The bill directly affects businesses paying corporate income tax in Michigan by altering the formulas or rules for allocating tax revenue. These changes focus on updating the legal framework for revenue distribution without creating new tax rates or programs.
SB 235 creates a corporate income tax credit for businesses that use sustainable aviation fuel (SAF). It directly affects airlines and fuel producers in Michigan by reducing their state tax liability based on the volume of SAF they utilize. The bill amends Michigan's tax code (MCL 206.1-206.847) to add a specific provision allowing corporations to claim this credit. This provides a financial incentive for adopting SAF, aiming to support cleaner aviation fuel adoption without specifying environmental outcomes.
SB 236 creates a tax credit program in Michigan to incentivize the production of sustainable aviation fuel (SAF). It directly affects fuel producers who meet specific environmental standards, requiring SAF to achieve at least a 50% reduction in life-cycle greenhouse gas emissions compared to petroleum fuel and comply with ASTM aviation fuel standards. Producers must apply to the Department of Environment, Great Lakes, and Energy for certification of their tax credit, providing evidence of domestic production, emissions reduction, and proof that the fuel was used in aircraft departing Michigan airports. The program administers tax credits through a state-certified process, aiming to boost local SAF production while meeting federal environmental benchmarks.
HB 4825 would create a tax credit for businesses that sell beverages in returnable containers (like soda cans or bottles), allowing them to deduct $0.005 per container sold from their Michigan corporate income tax starting in 2026. The credit amount would automatically increase each year based on inflation (using the U.S. Consumer Price Index) beginning in 2027. To claim the credit, businesses must attach a specific report (required under existing law) with their annual tax return. This policy directly affects beverage distributors who manage deposit systems for returnable containers, reducing their tax liability or generating refunds if the credit exceeds their tax bill.
HB 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.
HB 4124 creates a tax credit for Michigan corporations that spend money on research and development for advanced small modular nuclear reactors (SMRs). It directly affects companies developing this specific type of nuclear technology within the state. The bill adds new sections to Michigan's tax code, allowing businesses to claim a credit against their corporate income tax for qualifying R&D expenses related to SMRs. This policy change aims to incentivize investment in emerging nuclear energy technology within Michigan. The bill passed the House on October 28, 2025, with 78 yeas and 26 nays.
HB 4187 modifies Michigan's corporate income tax law by adjusting how the tax base is calculated and clarifying revenue distribution. It requires corporations to add back certain taxes and expenses previously deducted for federal purposes (like state taxes or related-party royalties) and eliminates deductions for oil/gas and mineral-related income and expenses. For the 2021-2022 fiscal year, the bill directs $800 million of corporate tax revenue to the Michigan taxpayer rebate fund, while other years’ revenue flows to the general fund. This directly affects corporations operating in Michigan and the state’s budget allocation process.
HB 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.
HB 5140 expands local governments' authority to impose hotel and short-term rental taxes. It allows cities in counties with 600,000-775,000 residents to levy up to 3% on accommodations (previously capped at 2%), while counties under 600,000 residents can tax up to 8% but require voter approval for rates above 5%. The bill directly affects hotels, vacation rentals, and online booking platforms that collect these taxes. Local governments must follow specific voter approval processes and administration rules under the amended law.
