Minnesota Child Support: How It Works, How It’s Calculated, and What You Need to Know

If you’re going through a divorce or custody matter in Minnesota, child support is one of the first things on your mind. How much will it cost? Who pays? Can it change later? These are real questions that deserve straight answers.

This guide covers every aspect of Minnesota child support law, from the calculation formula to big 2025 changes, with specific statute references and practical examples. It reflects the current law as of April 2026. It’s not meant to confuse you but to help you understand child support.

Minnesota’s child support system is governed entirely by Minn. Stat. Chapter 518A. The state uses what’s called the Income Shares model, meaning both parents’ incomes determine the support amount. This is different from some states that only look at the paying parent’s income.

What Is Child Support in Minnesota?

Child support in Minnesota is a court-ordered monthly payment from one parent to the other for the financial care of their child. Under Minnesota law, every child has the legal right to be financially supported by both parents, regardless of whether those parents were ever married. Minnesota child support has three components: basic support, medical support, and childcare support.

Basic support: covers the day-to-day costs of raising a child: food, housing, clothing, transportation, and education expenses.

Medical support: covers health insurance premiums and unreimbursed medical costs.

Childcare(daycare) support: covers work-related or education-related daycare and childcare expenses.

The obligation applies equally whether you went through a divorce, a custody proceeding, or a paternity action. If paternity has been established through a Recognition of Parentage or a court order, child support can be ordered. It does not matter whether the parents lived together.

Either parent can request child support. So can a grandparent or other relative who has legal custody of the child. The county attorney’s office can also initiate a child support action, which often happens when the custodial parent receives public assistance.

How Is Child Support Calculated in Minnesota?

Minnesota calculates child support using the Income Shares model under Minn. Stat. 518A.34. The court combines both parents’ monthly gross incomes, finds the basic support obligation on the guidelines table in Section 518A.35, then splits that amount proportionally based on each parent’s share of the combined income. The result is adjusted by a parenting expense adjustment based on overnight parenting time.

Here is the step-by-step process:

First, the court determines each parent’s gross monthly income. Then, those incomes are combined into a single number called the “combined parental income for determining child support,” which Minnesota abbreviates as PICS.

Second, the court looks up the PICS amount on the basic support guidelines table. This table, found in Minn. Stat. 518A.35, lists specific monthly support amounts for combined incomes ranging from under $1,400 per month all the way up to $20,000 per month, broken out by the number of children (one through six or more).

Third, the total support obligation is divided between the parents based on what percentage of the PICS each parent contributes. If one parent earns 60% of the combined income and the other earns 40%, the higher earner is responsible for 60% of the total support obligation.

Fourth, the parenting expense adjustment reduces the paying parent’s obligation based on how many overnights they have with the child. More overnights means a bigger reduction, because that parent is directly paying for expenses during their parenting time.

Ok, are you confused yet? Well the shortcut is right here:

What Income Counts Toward MN Child Support?

Under Minn. Stat. 518A.29, gross income for child support purposes is very broad. It includes wages, salary, commissions, bonuses, overtime pay, self-employment income, workers’ compensation benefits, unemployment insurance, Social Security benefits, pension and retirement fund distributions, VA benefits, trust income, annuities, capital gains, spousal maintenance received, and military pay.

You can see it includes nearly every sort of regular payment a person gets and the courts will usually err on the side of counting income in my experience, not excluding it.

It does not include income from public assistance programs like MFIP (Minnesota Family Investment Program), Supplemental Security Income (SSI), or food assistance.

If a parent is voluntarily unemployed or underemployed, the court can impute income. That means the court assigns an income level based on what that parent could reasonably be earning given their education, skills, and work history. This comes up frequently in contested cases, particularly when one parent quits a job or takes a lower-paying position around the time of a divorce or custody action.

How Does Parenting Time Affect Child Support?

Parenting time directly reduces the child support obligation through the parenting expense adjustment under Minn. Stat. 518A.36. The formula uses the number of court-ordered overnights each parent has per year.

A few key elements here, it’s COURT-ORDERED OVERNIGHTS, not just what the arrangement you have with your ex. If the order says you get 20% of the overnights, and you’ve unofficially changed it to week on week off, the Court will still need to use the 20% amount that is in the court order.

The math works by cubing (raising to the third power) the number of overnights for each parent, then weighting those numbers by each parent’s income share. This means that the adjustment is not linear. Small increases in parenting time around the 40-50% range produce proportionally larger reductions in the support obligation than the same increase at lower ranges.

If parenting time is equal (182.5 overnights each) and both parents earn the same income, no basic support is owed. In practice, most cases involve some income difference, so one parent still pays support even with a true 50/50 schedule.

What Expenses Can Impact Child Support?

Several expenses directly affect the calculation. Health insurance premiums paid by either parent for the child’s coverage are credited in the medical support calculation. Work-related or education-related childcare costs are split between the parents proportionally to income. Parenting time (overnights) adjusts the basic support figure downward for the parent with less time. And the number of non-joint children each parent supports can reduce their available income under the guidelines.

How Much Is Child Support for 1 Kid in Minnesota?

Child support for one child in Minnesota ranges from $50 per month to $1,839 per month, depending on the parents’ combined gross income. At a combined income of $6,000 per month, basic support for one child is approximately $864. The state caps basic support for one child at $1,839 per month when combined parental income exceeds $20,000 per month.

Here are some real examples from the guidelines table in Minn. Stat. 518A.35 to give you actual numbers:

Combined Monthly Income (PICS)	Basic Support: 1 Child
$2,000	~$288
$4,000	~$576
$6,000	~$864
$8,000	~$1,080
$10,000	~$1,224
$15,000	~$1,560
$20,000+	$1,839 (cap)

These figures represent the total basic support obligation before it is split between parents based on income share and before the parenting expense adjustment is applied. The actual amount one parent pays is typically lower than the table figure.

Keep in mind that with all the variables it’s easy to get confused, this is just the rough draft example from the State Website.

How Much Is Child Support for 2 Kids in Minnesota?

For two children, the basic support obligation is higher, but it does not double. At a combined monthly income of $6,000, basic support for two children is approximately $1,062. The statutory cap for two children at combined incomes above $20,000 per month is $2,541.

The guidelines reflect economies of scale. The cost per child decreases as you add children, because many household expenses (housing, utilities, transportation) serve all children in the home.

How Much Child Support Will I Pay If I Make $1,000 a Week?

If you earn $1,000 per week ($4,333 per month gross), your child support depends on the other parent’s income too. If the other parent earns $3,000 per month, the combined PICS is approximately $7,333. For one child, the basic support at that income level is roughly $996. Your share would be approximately 59% of that (your $4,333 out of the $7,333 combined), or about $588 per month before the parenting expense adjustment.

With a standard every-other-weekend parenting schedule (~86 overnights per year), the parenting expense adjustment would reduce that by a modest amount. With a more involved schedule (~128 overnights), the reduction is more significant.

How Much Child Support Will I Pay If I Make $2,000 a Week?

At $2,000 per week ($8,667 per month gross), the math shifts. If the other parent earns $4,000 per month, the combined PICS is $12,667. Basic support for one child at that level is approximately $1,400. Your income share is about 68%, making your obligation roughly $952 per month before the parenting time adjustment.

At higher income levels, the parenting expense adjustment matters more in raw dollar terms. A 50/50 schedule at this income level can reduce the obligation to a few hundred dollars per month, depending on the income difference between the parents.

Minnesota Child Support Calculator: How to Use It

Minnesota’s official child support calculator is free at childsupportcalculator.dhs.state.mn.us. You enter both parents’ gross monthly incomes, the number of children, overnights per parent, health insurance costs, and childcare costs. The calculator applies the formula from Minn. Stat. 518A.34 and 518A.35 and gives you an estimate of what a court would likely order.

To use the calculator, you need both parents’ gross monthly incomes, the number of children, the parenting time schedule (overnights per year for each parent), health insurance costs for the children, and any work-related childcare costs. Enter these figures and the calculator applies the statutory formula from Minn. Stat. 518A.34 and 518A.35.

A few things to know about the calculator. It gives you an estimate, not a court order. Judges have discretion to deviate from the guidelines in certain circumstances. The calculator also does not account for imputed income if a parent is voluntarily underemployed, which is a judgment call the court makes. And it does not factor in extraordinary medical expenses or other deviation factors.

That said, in the majority of cases handled in Hennepin, Ramsey, Dakota, and Anoka counties, the final court order falls very close to what the calculator produces. Judges in Minnesota take the guidelines seriously. Deviations happen, but they require specific findings on the record.

Is There a MN Child Support Worksheet?

Yes. Minnesota courts use a child support worksheet that walks through the calculation step by step. It is essentially the paper version of the online calculator. You can find the worksheet through the Minnesota Judicial Branch self-help center. In most counties, you are required to attach a completed worksheet to any motion involving child support.

Minnesota Child Support Guidelines and Laws

Minnesota child support guidelines are set by Minn. Stat. Chapter 518A and use the Income Shares model, where both parents’ incomes determine the support obligation. The guidelines are presumptive, meaning courts must follow them unless specific circumstances justify a deviation. Courts that deviate must make written findings explaining why under Minn. Stat. 518A.43.

The key statutory sections are 518A.26 (definitions), 518A.29 (gross income), 518A.34 (computation), 518A.35 (basic support guidelines table), 518A.36 (parenting expense adjustment), 518A.39 (modification), and 518A.41 (medical support).

The guidelines are presumptive, meaning courts are expected to follow them unless there is a specific reason to deviate. Under Minn. Stat. 518A.43, a court can deviate from the guidelines if strict application would be unjust or inappropriate, but the court must make written findings explaining why.

Common reasons courts deviate include extraordinary medical needs of the child, the educational needs of either parent (such as completing a degree), the standard of living the child would have enjoyed if the parents stayed together, and situations where one parent has significantly more assets but lower income.

What Is the “New” Law for Child Support in Minnesota?

Minnesota made several notable changes to its child support laws in 2025 that are now in effect. The biggest change is to the parenting expense adjustment. The old law used a threshold of 45.1% parenting time to qualify for the most significant adjustment. The 2025 update dropped that threshold to approximately 40%, meaning more parents now qualify for a meaningful reduction in their support obligation based on parenting time.

The calculation method also changed. Instead of using broad parenting time categories, the formula is now more granular. Each additional overnight matters. The math uses overnights raised to the third power, which means that small increases in time, particularly in the 40-50% range, produce proportionally larger reductions in support.

The self-support reserve also increased. It went from 120% of the federal poverty guideline to 130%, providing more protection for lower-income obligors so they can meet their own basic needs while paying support.

Minnesota also simplified the modification process, making it easier for people without attorneys to file for changes when circumstances shift. The official Minnesota Child Support Calculator was updated to reflect all of these changes.

Minnesota Supreme Court Rulings on Child Support

Minnesota appellate courts regularly weigh in on child support disputes, and their rulings shape how lower courts apply the guidelines. Recent decisions have addressed imputed income for self-employed parents, the treatment of bonuses and stock options in gross income calculations, and the scope of the court’s authority to deviate from the guidelines.

If you are involved in a contested child support case, recent case law matters. Court of Appeals and Supreme Court rulings fill in the gaps where the statutes leave room for interpretation. A family law attorney practicing in Minnesota will be up to date on which decisions are shaping outcomes in your county’s courts.

Do I Have to Pay Child Support with 50/50 Custody in Minnesota?

Yes, you can still owe child support in Minnesota with a 50/50 parenting time split. The key factor is income, not just time. If both parents have equal overnights but one parent earns more than the other, the higher-earning parent pays child support to the lower-earning parent. The amount will be smaller than it would be with a traditional every-other-weekend schedule, but it does not go to zero just because parenting time is equal.

Under Minn. Stat. 518A.36, the only situation where no basic support is owed is when parenting time is equal and parental incomes are also equal, and the court determines that child-related expenses are equally shared. That exact scenario is rare.

Here is a practical example. Parent A earns $7,000 per month. Parent B earns $4,000 per month. They share a 50/50 schedule. The combined PICS is $11,000. Basic support for one child at that level is approximately $1,320. Parent A’s income share is 64%. Parent A’s proportional obligation is $845. After the parenting expense adjustment for equal overnights, Parent A’s actual monthly payment to Parent B would be substantially reduced, but it would not be zero.

This is one of the most commonly misunderstood aspects of Minnesota child support. Many parents assume 50/50 means no support. It does not, unless the incomes also happen to be equal.

How to Modify Child Support in Minnesota

To modify child support in Minnesota, you or the other parent must file a motion with the court that issued the original order. Under Minn. Stat. 518A.39, a modification requires showing that circumstances have changed enough to make the current order unreasonable and unfair. There is a clear threshold: if recalculating support under the current guidelines would produce a number at least 20% and at least $75 per month different from the current order, a change is presumptively warranted.

The process works like this. You prepare and file a motion to modify child support with the court in the county where the original order was entered. You include a current financial affidavit and a completed child support worksheet showing the proposed new amount. The other parent is served with the motion and has a chance to respond. The court then either decides the motion on the papers or schedules a hearing.

When Can You Modify Child Support in MN?

Common triggers for modification include a substantial increase or decrease in either parent’s income, a change in parenting time, new childcare or medical expenses, the child aging out of daycare, a job loss (involuntary), a change in the number of children being supported, or either parent receiving public assistance.

Under the 2025 changes, the process is also more accessible for people filing without an attorney. Simplified forms and a streamlined process make it possible for pro se litigants to request modifications more easily than in previous years.

How Long Does a Child Support Modification Take?

In most Minnesota counties, a straightforward modification takes 60 to 90 days from filing to a new order, assuming the other parent does not contest it. Contested modifications, where the parents disagree on income or other factors, can take 3 to 6 months or longer, depending on the county’s calendar and whether discovery (financial document exchange) is needed.

One important detail: modifications are only retroactive to the date the other parent is served with the motion. If your income dropped six months ago but you just now filed, the court cannot go back to the date of the income change. The effective date is the service date. This is why filing promptly matters when circumstances change.

When Does Child Support End in Minnesota?

In Minnesota, child support automatically ends when the child turns 18. If the child is still attending secondary school (high school) full-time at age 18, support continues until the child turns 20 or completes secondary school, whichever comes first. Support can also terminate earlier if the child is emancipated by a court, gets married, or enlists in the military.

If the child has a physical or mental disability that prevents self-support, the court can order support to continue beyond age 18 for as long as the disability persists. This is not automatic. The parent seeking continued support must file a motion and provide evidence of the disability and the child’s ongoing need.

Child support for each child ends independently. If you have two children and the older one turns 18 (or 20), the support obligation is recalculated for the remaining child or children. The amount does not just decrease by half, because the guidelines table reflects that the per-child cost is not uniform.

How to Stop Child Support in Minnesota

If your child has turned 18 (or 20 if still in high school) and your child support has not automatically terminated, you need to file a motion with the court to end the obligation. In some counties, the child support office handles this administratively when they receive proof the child has aged out. In other counties, it requires a court order. If you have arrears (past-due amounts), those do not go away when the child ages out. You still owe any unpaid balance, and enforcement continues until it is paid.

What Happens If You Don’t Pay Child Support in Minnesota?

If you don’t pay child support in Minnesota, the state enforces through wage garnishment, tax refund intercepts (state and federal), driver’s license suspension, passport denial, professional license suspension, property liens, credit bureau reporting, contempt of court proceedings, and criminal prosecution for serious arrears. Both the county child support agency and the Minnesota Department of Children, Youth, and Families (DCYF) have enforcement authority.

The most common enforcement method is income withholding. In the majority of Minnesota child support cases, payments come directly out of the obligor’s paycheck before they ever see the money. This is not just for people who fall behind. It is the default for nearly all child support orders. If the obligor is self-employed or changes jobs frequently, other methods come into play.

How Long Can Someone Not Pay Child Support Before They Go to Jail?

There is no specific number of months that triggers jail time automatically. Jail for unpaid child support in Minnesota happens through contempt of court proceedings. The custodial parent or the county attorney files a motion for contempt, and the court holds a hearing. If the court finds that the obligor has the ability to pay but is willfully refusing, the court can order jail time. In practice, judges in Minnesota use jail as a last resort after other enforcement methods have failed.

Felony-level criminal charges are possible under Minnesota law when the obligor owes more than $10,000 in arrears or has not paid anything for six months or more. Conviction can result in up to two years in prison.

Can They Take My Tax Refund for Child Support?

Yes. Minnesota participates in both the federal and state tax refund intercept programs. If you owe child support arrears, the state can intercept your federal tax refund through the Federal Tax Refund Offset Program and your Minnesota state tax refund. There is a minimum arrears threshold to trigger the intercept, and you will receive notice before it happens, but once the intercept is processed, the money goes directly to the custodial parent.

Can They Suspend My Driver’s License?

Yes. Under Minnesota law, the state can suspend your driver’s license, recreational vehicle licenses, and professional or occupational licenses if you are behind on child support. The Department of Children, Youth, and Families can initiate the suspension process, and it can also result in denial of a U.S. passport for arrears exceeding $2,500.

Minnesota Child Support and Medical/Childcare Costs

Minnesota child support includes three separate obligations: basic support, medical support, and childcare support. Medical support covers health insurance premiums and unreimbursed medical expenses, split proportionally between parents by income. Childcare support covers work-related or education-related daycare costs, also split by income. Both are ordered on top of the basic support amount under Minn. Stat. 518A.41.

How Is Medical Support Calculated?

Under Minn. Stat. 518A.41, medical support requires that the child be covered by health insurance. If one parent has coverage available through their employer, they are typically ordered to provide it. The cost of the child’s share of the premium is then divided between the parents in proportion to their incomes. If the child is covered by Medical Assistance (MinnesotaCare or Medicaid), a cash contribution toward medical support may be ordered instead.

Unreimbursed medical and dental expenses (co-pays, deductibles, orthodontics, therapy) are split between the parents proportionally to their incomes. This is a separate obligation from the monthly premium-sharing.

How Is Child Care Support Calculated?

Childcare costs related to employment or education are divided between the parents in proportion to their incomes. If one parent pays $1,200 per month for daycare so they can work, and that parent earns 45% of the combined income, the other parent is responsible for 55% of that $1,200, or $660 per month, in addition to the basic support obligation.

Childcare support is often one of the most fluid components of child support. It changes as children age out of daycare, as school schedules shift, and as parents change employment. When childcare costs change substantially, it is a valid basis for requesting a modification of the support order.

Frequently Asked Questions About Minnesota Child Support

How much is child support for one kid in Minnesota?

Basic support for one child ranges from $50 to $1,839 per month depending on both parents’ combined incomes. At a combined income of $6,000 per month, it is approximately $864 before parenting time adjustments.

How is child support calculated in Minnesota?

Minnesota uses the Income Shares model. Both parents’ gross incomes are combined, the court looks up the obligation on the guidelines table in Minn. Stat. 518A.35, splits it proportionally by income, and adjusts for parenting time overnights.

Do I have to pay child support with 50/50 custody?

Yes, in most cases. If you earn more than the other parent, you will pay child support even with equal parenting time. The amount is reduced by the parenting expense adjustment, but it does not go to zero unless both incomes and time are truly equal.

When does child support end in Minnesota?

Child support ends at age 18, or age 20 if the child is still in high school full-time. It can end earlier through emancipation, marriage, or military enlistment. The court can extend it beyond 18 for a child with a disability.

How do I modify child support in Minnesota?

File a motion with the court showing a substantial change in circumstances. A modification is presumed warranted if recalculating the amount would result in a change of at least 20% and $75 per month from the current order (Minn. Stat. 518A.39).

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

Minnesota enforces through wage garnishment, tax refund intercepts, driver’s license suspension, passport denial, property liens, credit reporting, contempt of court, and criminal prosecution for serious arrears.

What is the new child support law in Minnesota?

The 2025 changes lowered the parenting expense adjustment threshold from 45.1% to approximately 40% parenting time, increased the self-support reserve to 130% of the federal poverty guideline, and simplified the modification process. The official calculator has been updated accordingly.

What income counts for child support in Minnesota?

Under Minn. Stat. 518A.29, gross income includes wages, salary, bonuses, self-employment income, workers’ comp, unemployment, Social Security, pensions, VA benefits, trust income, and capital gains. It excludes means-tested public assistance like MFIP and SSI.
