How much child support in Minnesota?

Each parent's monthly income (PICS) is added together. The state table gives basic support for that combined income and the number of children, and each parent pays a share by percentage of income. Child care and medical support are added, and the amount is adjusted for parenting time.

Law: Minn. Stat. §§518A.26 to 518A.43

We don't estimate Minnesota's amount here: its formula uses both parents' incomes and other facts, and a home-made number could mislead you. The official tool gives the real starting number:

How to open a case

Apply for child support services through your county child support office. If you get MFIP, Medical Assistance or child care assistance, a case may be opened for you. You can also ask the district court for support in a divorce, custody or parentage case.

Yearly fee

$35 a year for a parent who has never received public assistance, once at least $550 has been collected; it is taken from support collected, but not from the first $550. If you applied for full services, there is also a 2% cost recovery fee on support collected (not charged while you get MFIP, foster care or Medical Assistance, or until 24 months after MFIP or foster care ends), and $25 for each successful federal tax refund intercept.

Law: Minn. Stat. §518A.51

Paternity (legal fatherhood)

Unmarried parents can sign a Recognition of Parentage in front of a notary and file it with the state registrar of vital records. If parentage is disputed, the court or the county child support office can order genetic tests, and must if a party asks.

How it works

Each parent's monthly income (PICS) is added together. The state table gives basic support for that combined income and the number of children, and each parent pays a share by percentage of income. Child care and medical support are added, and the amount is adjusted for parenting time.

Low income

Support is presumed not to exceed the paying parent's ability to pay: a self-support reserve of 120% of the federal poverty guideline for one person is subtracted from that parent's income. The minimum basic support is $50 a month for one child, $60 for two, up to $100 for six or more, and a parent ordered to pay the minimum is presumed unable to pay child care and medical support.

Law: Minn. Stat. §518A.42

Official calculator
Official Minnesota child support calculator
Health insurance and medical costs

The court orders medical support, which can include private health coverage and a share of uninsured costs. Private dependent coverage is presumed affordable if the premium for the child is no more than 5% of the parents' combined monthly income. A paying parent with income under 200% of the poverty guideline, or on public assistance, is not ordered to contribute toward public health coverage.

Change a child support order in Minnesota

When a change is allowed

A change is presumed when the guidelines applied to current circumstances give an amount at least 20% and at least $75 a month higher or lower than the current order (if the order is under $75, at least 20%), or when a parent's gross income has dropped at least 20% through no fault or choice of their own. Other reasons include substantially changed income or needs, changed health coverage or child care costs, or emancipation of a child. Having a new child with someone else does not by itself justify a change.

Law: Minn. Stat. §518A.39, subd. 2

How to ask

File a motion to modify in district court, or ask your county child support office (the public authority), which can bring the motion. Serve a copy on the county if payments go through it.
