House Bill 4057 amends Michigan’s Income Tax Act, section 30, which defines “taxable income” for individual taxpayers. The bill largely updates and restates the list of additions and deductions used to calculate Michigan taxable income, including existing deductions for retirement and pension income, Social Security, military pay, education savings accounts, ABLE accounts, first-time home buyer savings accounts, wrongful imprisonment compensation, wagering losses, and certain tribal income. It also preserves the state’s personal exemption structure and the special exemption rules for disabled individuals, veterans, and certain family circumstances.
The most notable substantive change is a new deduction for contributions to a child care savings account, effective for tax years beginning on or after January 1, 2026. Under that provision, taxpayers could deduct contributions net of qualified withdrawals, up to $10,000 for a single return or $20,000 for a joint return, with related interest and qualified distributions also addressed in the tax base rules. The bill also includes conforming add-back rules for nonqualified withdrawals from child care savings accounts, similar to the treatment already used for education savings, ABLE, and first-time home buyer savings accounts. The bill is tied to House Bill 4056, meaning it would not take effect unless that companion bill is enacted.
In addition to the child care savings account deduction, the bill makes several technical and policy updates to the retirement and pension deduction framework. It continues the phased-in expansion of retirement income deductions for certain taxpayers, including older taxpayers and some public safety retirees, and retains existing age-based limitations and CPI adjustments. The bill also keeps the current treatment of oil and gas income, senior citizen investment income deductions, and other specialized tax preferences in place, while reorganizing the statute to incorporate prior amendments and future effective dates.
The general sentiment reflected by the bill text and available context appears neutral to favorable toward tax relief and savings incentives, especially for families and retirement-age taxpayers. No committee transcripts or recorded votes were provided, so there is no direct evidence of floor or committee debate. Based on the structure of the bill, it appears designed as a policy expansion rather than a controversial overhaul, with the child care savings deduction likely intended to encourage long-term saving for child care expenses.
The main point of potential contention is fiscal impact, since the bill would reduce taxable income for contributors to child care savings accounts and therefore lower state income tax revenue. Another possible issue is the bill’s complexity: it adds a new savings-account deduction to an already detailed set of tax adjustments, exemptions, and phase-ins, which may raise administrative and compliance questions. Because the bill is tied to HB 4056, its effect also depends on enactment of the companion measure, making the package procedurally linked as well as substantively connected.
HB 4057 would amend Michigan Compiled Laws section 206.30 of the Income Tax Act of 1967, changing the calculation of individual taxable income by adding a new deduction for child care savings account contributions and related earnings/distributions, and by adding conforming add-back rules for nonqualified withdrawals. It would also continue and restate existing deductions and exemptions for retirement income, Social Security, military and public safety pensions, education savings accounts, ABLE accounts, first-time home buyer savings accounts, wrongful imprisonment compensation, wagering losses, and certain tribal income. The bill would affect individual taxpayers, especially families saving for child care and taxpayers already using other state-favored savings vehicles, while leaving the corporate income tax framework untouched. The act would not take effect unless the companion bill, HB 4056, is enacted.
The available context suggests a generally supportive or at least noncontroversial posture toward the bill’s policy goals, with the measure framed as a tax deduction for child care savings and a continuation of existing tax preferences. No committee testimony or vote record was provided, so there is no direct evidence of opposition or support from legislators. On its face, the bill appears aimed at providing tax relief and encouraging savings, which typically draws favorable sentiment among proponents of family-oriented tax policy.
The most likely area of contention is the revenue effect of creating a new income tax deduction, since reducing taxable income can lower state receipts. A second issue is whether the child care savings deduction is the best or most equitable way to support families, given that it benefits taxpayers able to set aside money in advance. The bill’s extensive technical amendments and tie-bar to HB 4056 may also draw procedural scrutiny, because its implementation depends on another bill becoming law.
