Michigan operates under the Income Shares model, one of 42 U.S. states using this framework. For a parent supporting one child, the base guideline applies roughly 18% of income, scaling to 26% for two children and 32% for three. That places Michigan at rank #18 of 51 states by single-child base percentage. Unlike capped states, there is no statutory income ceiling — the formula applies to the full reported income before deductions. Median household income across Michigan is $63,498 annually, which shapes the real-world dollar obligations families face under these percentages.
On the enforcement side, the Michigan child support program manages 679,000 active cases and collected approximately $1,200 million in the most recent OCSE reporting year. The state's collection rate of 58.1% compares to a national average of 60.6% across reporting states — placing Michigan at rank #35 of 51 on collection efficiency, and rank #6 by caseload volume (national average: 285,686 cases per state). Paternity is established in 94.6% of Michigan cases, compared to 94.9% nationally — a critical step because child support orders cannot be enforced without legal parentage on record. Orders are in place for 73.7% of the caseload.
Context matters when interpreting these numbers. A higher percentage-of-income figure does not automatically mean higher dollar obligations — the underlying income brackets, deductions, parenting-time adjustments, and self-support reserves vary meaningfully between states. Michigan allows a parenting time adjustment, which can materially reduce the base obligation when the non-custodial parent exercises substantial overnight time. Our interactive Michigan calculator applies these guidelines to specific income and custody scenarios. Data sources: OCSE FY2022 Annual Report, Michigan Revised Statutes, and Census ACS 2022.
Michigan uses the Income Shares model. Both parents' incomes are combined, the total obligation is looked up from a schedule, then split proportionally based on each parent's income share.
