Minnesota Child Support Laws (2026): Guidelines & Calculator

Frequently Asked Questions

How is child support calculated in Minnesota?

Minnesota uses the Income Shares Model under Minnesota Statutes section 518A.35. Both parents' gross incomes are combined to determine the Parental Income for Child Support (PICS). The court looks up the basic support obligation in the statutory guideline table based on the combined PICS and number of children, then divides the obligation based on each parent's proportionate share of income. A parenting expense adjustment is applied based on court-ordered parenting time. The state provides an online calculator at childsupportcalculator.dhs.state.mn.us to estimate amounts.

When does child support end in Minnesota?

Child support ends when the child turns 18 or graduates from high school, whichever occurs later, and no later than age 20 where the obligation rests on age or school enrollment. If a child turns 18 during their senior year, support continues through graduation. Section 518A.26 defines a third category of child with no age limit at all: an individual who, by reason of physical or mental condition, is incapable of self-support, so support may continue indefinitely in that situation. Support does not automatically end just because the child moves out of the custodial parent's home.

What changed in Minnesota child support law in 2025?

Several changes took effect in 2025. The self-support reserve under section 518A.42 remains at 120% of the federal poverty guideline for one person. Subtracting it from PICS produces the obligor's income available for support, which caps the obligation calculated under section 518A.34 rather than reducing the income the guideline runs on. Social Security and veterans disability benefits received for a joint child can now be credited against arrears upon a modification motion. A separate bill (HF 2456) would phase out biennial COLA adjustments after January 1, 2027; its enactment status should be confirmed with your county child support office.

How can I modify a child support order in Minnesota?

You can petition for modification under Minnesota Statutes section 518A.39 based on a substantial change in circumstances. The law presumes modification is warranted when the current guideline calculation differs from the existing order by at least 20% and $75 per month, or when a parent's income has decreased by 20% or more through no fault of their own. Other grounds include changes in healthcare costs, childcare expenses, or a child's emancipation. Contact the ezDocs system or call 651-531-5655 to start the process.

What happens if you don't pay child support in Minnesota?

Minnesota enforces child support orders through automatic income withholding, bank account garnishment, tax refund intercepts, credit bureau reporting, license suspensions, passport denial, and property liens. Criminal penalties apply for willful non-payment: a gross misdemeanor charge carries up to 1 year in jail and a $3,000 fine, while a felony charge carries up to 2 years in prison and a $5,000 fine. There is no statute of limitations on collecting child support arrears in Minnesota.

How Minnesota Calculates Child Support

  • Minnesota's guidelines run on ADJUSTED GROSS income: income taxes and FICA are never subtracted. The only adjustments to gross income are items like court-ordered child support or maintenance a parent actually pays for other cases. Enter income before taxes.
  • Minnesota uses the Income Shares model under Minn. Stat. § 518A.35, combining both parents' parental income for child support (PICS) to determine the basic child support obligation.
  • The basic obligation is taken from the statutory guidelines table (Minn. Stat. § 518A.35) and prorated between parents based on each parent's share of combined PICS.
  • Minnesota uses three parenting time categories: less than 10% (no adjustment), 10-45% (moderate adjustment), and 45.1%+ (~146 overnights — full parenting expense adjustment).
  • Health insurance premiums (medical support), work-related childcare costs, and unreimbursed medical expenses are added to the basic obligation and divided proportionally between parents.
  • Parental income for child support (PICS) is calculated from gross income minus certain deductions including taxes, Social Security, union dues, and pre-existing support obligations (Minn. Stat. § 518A.29).
  • Courts may deviate from the guidelines upon a written finding that the guidelines amount would be unjust or inappropriate under the circumstances (Minn. Stat. § 518A.43).
  • Minnesota requires both parents to provide medical support (health insurance or a cash equivalent) for children in addition to basic child support.

Updates

Corrected the self-support reserve explanation to reflect that it caps the calculated obligation rather than reducing the income the guideline runs on, clarified that support has no age limit for a child incapable of self-support due to a physical or mental condition, and updated the state calculator to its current version.

Independently fact-checked against the cited primary sources; governing law re-checked for recent changes

Removed the unsupported claim that a 2025 amendment lowered the parenting-expense-adjustment threshold from 45.1% to 40% parenting time; the linked current statute (518A.36) computes the adjustment with a continuous overnights-cubed formula that has no percentage threshold, so the description was corrected to match the statute's actual mechanism everywhere the claim appeared on the page.
