Minnesota law provides the mathematical formula and the income charts that instruct parents and the court on how to decide the correct amount of child support payments. This mathematical formula is called "income shares." Income shares requires the court to consider both parents' gross monthly income and, after credits and deductions, determine the amount of child support from the chart, dividing the total support obligation to each parent according to their percentage of the total combined income of both parents.
Consideration in the form of deductions or credits may be given for other children in the home; court-ordered child support payments for other children; parenting time; and a set amount is deducted for the living expenses of the noncustodial parent. Basic support, medical support and child care support are all calculated similarly, using additional charts if medical assistance, MinnesotaCare or Child Care assistance is being expended for the child(ren).
