The 2025 Michigan Child Support Formula and High-Income Parents | Child Support Attorney

If you are a high earner in metro Detroit heading into a divorce or support case, you probably want to know how the 2025 Michigan Child Support Formula and high-income parents fit together, and whether a large income means a large support number. The short answer is that the same formula governs your case as everyone else’s, and Hermiz Law helps parents across Oakland, Macomb, and Wayne counties understand how their income is treated under it. Knowing how the formula reads your earnings is the first step toward a fair result.

The 2025 Michigan Child Support Formula, often called the 2025 MCSF, is the calculation method Michigan uses to determine the amount of child support, and the amount of support is determined by applying it (MCL 552.501 et seq.). This page explains what the 2025 MCSF is and that it governs Michigan child support now, how the formula defines income using each parent’s net income and a broad list of income sources, and how high incomes are handled, including when a court may deviate from the formula. Understanding those pieces helps a high earner see how a support figure is actually built.

Madana M. Hermiz is the founding attorney of Hermiz Law, a Troy, Michigan firm focused on divorce and family law throughout metro Detroit. She represents parents in divorce and support matters governed by the same Michigan Child Support Formula discussed on this page. Her practice centers on making sure a parent’s income is characterized accurately and the resulting support number reflects what the formula actually requires.

 What Is the 2025 Michigan Child Support Formula? | Child Support Attorney

The 2025 Michigan Child Support Formula is the method Michigan courts use to set the amount of child support, and it is referenced throughout Michigan family law practice as the 2025 MCSF. Under Michigan law, the amount of support is determined by the MCSF (MCL 552.501 et seq.), and the 2025 MCSF Manual, along with the 2025 MCSF Supplement containing the current economic data and tables, is published by the State Court Administrative Office through the Friend of the Court Bureau. The formula is what a court, or the Friend of the Court, applies to arrive at a support figure.

 The Formula Governs Michigan Child Support

Michigan does not leave the child support amount to a judge’s unguided discretion. The court must order support in an amount determined by applying the child support formula, unless it makes specific findings to deviate (MCL 552.605(2)). For a high earner, that starting point matters, because the calculation runs the same way regardless of income level, and the figure it produces is presumed correct until a reason to depart is established on the record.

 How the 2025 MCSF Defines Income

Income is the engine of the 2025 MCSF, and the formula reads it broadly. The objective of determining income is to establish, as accurately as possible, how much money a parent should have available for support, and all relevant aspects of a parent’s financial status are open for consideration (2025 MCSF 2.01(B)). For a high earner, this means the analysis is not limited to a single salary line on a pay stub.

 Net Income, Not Gross Income

The 2025 MCSF calculates support using net income, not gross income (2025 MCSF, net income provisions). Net income is what remains after the formula’s allowable deductions, so those deductions matter just as much as the income sources themselves. Because the formula estimates taxes and applies deductions to reach net income, two calculation tools can reach slightly different results depending on the assumptions used, which is one reason the underlying inputs deserve careful attention for a high earner.

 The Broad List of Income Sources

The 2025 MCSF counts far more than wages when it defines income. The formula’s list of income sources includes, among other categories, the items summarized below, and it also counts spousal support paid by someone who is not the other parent (2025 MCSF 2.01(F)) and, for a self-employed parent, business owner, or executive, income derived from distributed profits, fees, commissions, and certain other business items (2025 MCSF 2.01(E)).

A high earner’s income often includes several of these categories at once, which is exactly why an accurate characterization of each source matters. Certain means-tested benefits, such as Temporary Assistance to Needy Families, food stamps, the federal Earned Income Credit, and Supplemental Security Income, are not counted as income for child support (2025 MCSF 2.04(A)).

When your income comes from bonuses, capital gains, rental property, or a business, how each piece is characterized under the 2025 MCSF can move the support figure meaningfully.

 How the 2025 MCSF Handles High-Income Parents

High income does not put a parent outside the 2025 MCSF. The same formula applies, run on that parent’s net income and the other formula inputs, and it is what generates the presumptive support amount. What changes with a large income is not the method but the size of the numbers going into it, and the questions that can arise about whether the result fits the family’s actual circumstances.

 When Support Would Exceed What the Child Needs

A frequent concern for high earners is that the formula could produce support that is more than the child needs. Michigan courts have addressed this directly: it is unnecessary to deviate a support award downward simply because it is more than the child needs, because the MCSF already incorporates both a child’s needs and the parent’s resources (Riemer v Johnson, 311 Mich App 632 (2015), citing Burba). In other words, the formula is designed to balance need and resources on its own, so a high number is not, by itself, a reason to depart from it.

Income disparity between the parents is treated the same way. Income disparity by itself is not a sufficient basis for deviating from the formula, so the gap between a high earner and a lower earning parent does not, standing alone, justify a different result (per Burba and the deviation standard). The formula, not the size of the paycheck, remains the reference point.

 Deviating From the 2025 MCSF

Deviation from the formula is possible, but it is the exception and it is controlled. A court may enter a support order that deviates from the formula if applying the formula would be unjust or inappropriate (MCL 552.605(2)). The 2025 MCSF contains an extensive list of factors a court may consider in exercising its discretion to deviate (2025 MCSF 1.04(E)), and the existence of a deviation factor does not require deviation.

 What the Court Must Put on the Record

When a Michigan court deviates from the formula, it cannot do so silently. The court must set forth in writing or on the record the support amount determined under the formula, how the order deviates from it, the value of any property or other support awarded in lieu of support, and the reasons application of the formula would be unjust or inappropriate in the case (MCL 552.605(2); 2025 MCSF 1.04(E)). For a high-income parent seeking or opposing a deviation, this record requirement is where the argument is actually won or lost.

 Ready to Discuss a Formula Deviation With a Michigan Divorce Attorney?

Whether a deviation from the 2025 MCSF is appropriate in your case depends on specific facts the court must weigh and state on the record. Call Hermiz Law at (248) 825-8042 to review whether the formula result fits your situation or whether a deviation should be argued in your metro Detroit case.

 Frequently Asked Questions About the 2025 Michigan Child Support Formula and High Earners

 Does the 2025 Michigan Child Support Formula apply to high-income parents?

Yes. The 2025 MCSF governs Michigan child support, and the court must order support in an amount determined by applying the formula (MCL 552.605(2)). High income does not remove a parent from the formula; it simply means larger figures are used as inputs.

 Does the Michigan formula use gross income or net income?

The 2025 MCSF calculates support using net income, which is income after the formula’s allowable deductions. Because the formula estimates taxes and applies deductions to reach net income, the deductions matter as much as the income sources when the number is calculated.

 What counts as income under the 2025 MCSF?

The formula reads income broadly. Along with wages, it counts sources such as bonuses, tips, perks and in-kind income, capital gains, rental income, and employer contributions to retirement plans (2025 MCSF 2.01(C)), and, for business owners, distributed profits and fees (2025 MCSF 2.01(E)). Certain means-tested benefits are not counted (2025 MCSF 2.04(A)).

 Can a Michigan court reduce support because it is more than the child needs?

Not automatically. Michigan courts have held that it is unnecessary to deviate a support award downward simply because it exceeds what the child needs, because the MCSF already incorporates both the child’s needs and the parent’s resources (Riemer v Johnson). A high support figure is not, by itself, a reason to depart from the formula.

 When can a Michigan court deviate from the child support formula?

A court may deviate only if applying the formula would be unjust or inappropriate (MCL 552.605(2)). If it deviates, the court must state on the record the formula amount, how the order departs from it, and the reasons the formula would be unjust or inappropriate (2025 MCSF 1.04(E)). Income disparity by itself is not a sufficient basis to deviate.
