HB 4287 amends Michigan’s Income Tax Act to create a new tax treatment for broadband expansion grants and related expenses. For individual income tax purposes, the bill allows taxpayers to deduct grant money received for the purpose of providing, improving, or expanding broadband in Michigan if the grant comes from specified state, local, federal, or tribal broadband programs. It also requires taxpayers to add back expenses, including depreciation, that were deducted in arriving at adjusted gross income when those expenses are attributable to an eligible broadband grant. The bill makes parallel changes to the corporate income tax and the flow-through entity tax so that the same grant income is excluded and related expenses are added back in those tax bases as well.
The bill is written to apply retroactively to tax years beginning on or after January 1, 2023, meaning it would affect prior tax filings for those years. In addition to the broadband provisions, the bill restates and carries forward a large number of existing income tax deductions, exemptions, and limitations in section 30, including retirement and pension deductions, senior citizen deductions, education savings account deductions, ABLE account deductions, first-time home buyer savings account deductions, wrongful imprisonment compensation, disabled veteran student loan discharge income, wagering losses, and tribal member income provisions. Most of those provisions appear unchanged in substance, with the broadband grant language being the principal policy change.
The overall sentiment around the bill appears strongly favorable. It was reported from committee without amendment on a 14-0 vote and then passed House third reading with immediate effect by a wide 97-8 margin. That voting pattern suggests broad bipartisan support or at least little organized opposition to the measure as drafted.
The main point of contention, to the extent one is visible from the bill text and vote history, is not the broadband tax exclusion itself but the complexity and breadth of the tax code amendments. The bill touches multiple tax bases and includes detailed cross-references to many grant programs, which may raise administrative and compliance questions for taxpayers and the Department of Treasury. The retroactive effective date could also be a point of concern for filers who already reported 2023 income, though the available vote history does not show significant resistance on that basis.
HB 4287 would amend MCL 206.30, 206.623, and 206.815 to exclude qualifying broadband expansion grant money from Michigan taxable income, corporate income tax base, and flow-through entity tax base, while requiring related grant-funded expenses to be added back. It would apply retroactively to tax years beginning on or after January 1, 2023, potentially affecting prior returns and refunds. The bill does not repeal existing deductions, but it adds a new category of tax treatment for broadband deployment funding and aligns the individual, corporate, and flow-through entity tax provisions.
The bill appears to have received very positive treatment in the Legislature. It was reported from committee unanimously and then passed the House by a substantial margin, including immediate effect. The available record suggests little opposition and a general consensus in favor of providing tax relief or clarification for broadband expansion grants.
The principal policy issue is the scope and administration of the broadband grant exclusion: the bill covers a long list of federal and state broadband programs and requires a matching add-back for related expenses, which could create compliance complexity. The retroactive application may also be debated because it affects tax years already in progress or completed. However, based on the vote totals, these concerns did not generate major visible opposition in the House.
