How Michigan Calculates Child Support

Michigan calculates child support using the Income Shares model as established under Michigan Compiled Laws Section 552.519 and the Michigan Child Support Formula. This model is designed to ensure that children receive the same proportion of parental income they would have received if the parents lived together. Both parents' net incomes are combined and applied to the Michigan Child Support Formula to determine the total support obligation.

Michigan's formula incorporates a detailed parenting time adjustment that reflects the direct costs each parent incurs during their time with the child. The number of overnights is a key factor, and the formula provides different calculation methods for sole custody, shared custody, and split custody arrangements. Michigan uses the MiCSES (Michigan Child Support Enforcement System) software to calculate support in court proceedings, and the state's Friend of the Court office assists with enforcement and modification of support orders.

In addition to the base support obligation, Michigan allocates health care expenses proportionally between the parents. This includes health insurance premiums and out-of-pocket medical costs that exceed a reasonable threshold. Childcare expenses necessary for employment or education are also factored into the calculation. The court may deviate from the formula when applying it would be unjust or inappropriate, considering factors such as the child's special needs, the standard of living, and each parent's financial resources.

Frequently Asked Questions

How does Michigan calculate child support under MCL 552.519?
Michigan uses an Income Shares model under Michigan Compiled Laws Section 552.519. Both parents' net incomes are combined and applied to the Michigan Child Support Formula to determine the total support obligation. Each parent is responsible for their proportional share based on their percentage of the combined net income.
What is considered income for Michigan child support?
Michigan considers gross income from all sources including wages, salaries, commissions, bonuses, self-employment income, rental income, investment income, pension and retirement income, Social Security benefits, unemployment benefits, and workers' compensation. Net income is calculated by subtracting federal and state taxes, FICA, mandatory union dues, and certain other deductions.
Does parenting time affect Michigan child support?
Yes. Michigan's child support formula includes a parenting time adjustment based on the number of overnights the non-custodial parent has with the child. The formula accounts for the direct costs each parent incurs during their parenting time, and the adjustment increases as the number of overnights increases. Shared parenting arrangements can significantly reduce the support obligation.
What additional expenses are included in Michigan child support?
Michigan child support may include health care expenses (insurance premiums and out-of-pocket medical costs), childcare expenses necessary for a parent to work or attend school, and other extraordinary expenses. These additional costs are allocated between the parents in proportion to their incomes and added to the base support amount.
Can Michigan child support be modified?
Yes. Michigan allows modification of child support orders when there has been a significant change in circumstances that makes the existing order unreasonable. Common reasons include substantial changes in income, changes in custody or parenting time, or changes in the child's needs. Either parent can file a motion with the Friend of the Court or the circuit court to request a modification.
