Individual income tax: deductions; contributions to a child care savings account; deduct. Amends sec. 30 of 1967 PA 281 (MCL 206.30). TIE BAR WITH: HB 4056'25

HB 4057 amends Michigan's individual income tax code to adjust how certain deductions are calculated for taxpayers. It specifically modifies Section 30 of the Income Tax Act, affecting Michigan residents who claim deductions for retirement benefits (including Michigan National Guard pensions), education trust payments, and other income adjustments. Key provisions clarify that taxpayers can deduct payments made under Michigan's advance tuition payment contracts for higher education, with specific limits ($42,240 single/$84,480 joint) and annual inflation adjustments. The bill does not create a new child care savings account deduction (that appears related to HB 4056), but refines existing education and retirement-related tax rules. This change directly impacts individual taxpayers using these specific deduction categories when filing Michigan state taxes.
