Minnesota Child Support Guide (2026): How It Is Calculated, What Counts as Income, Business Owners, Imputed Income, Modification and What Happens If You Don’t Pay

I have been a Minnesota family lawyer since 2000 and have handled hundreds of child support cases, from the simple ones where both parents have a W-2 and the calculator does the work, to the ones with a family business, a parent who suddenly stopped working, or $30,000 in arrears. Child support is one of the first questions every parent asks me. How much will it be? Who pays? What if my ex owns a business? What if she quits her job? What happens if I fall behind?

This guide answers those questions the way I would if you were sitting across the desk from me in Mankato or Rochester. It walks through the formula with real numbers from the statutory table, spends real time on business owners and imputed income because that is where most of the fights happen, and lays out exactly what Minnesota can do to a parent who does not pay. Everything here reflects Minnesota law as of October 2026, and every statute is linked so you can read it yourself.

Minnesota Child Support at a Glance

Question	Answer
What law governs child support?	Minn. Stat. Chapter 518A, the Minnesota child support guidelines, applied the same way in every county.
Whose income counts?	Both parents’ gross income, before taxes (Minn. Stat. 518A.29).
What are the three parts of support?	Basic support, medical support and child care support. Each is ordered separately.
Does parenting time reduce support?	Yes, through a formula based on court-ordered overnights (Minn. Stat. 518A.36). More overnights, less support, but the reduction is small until the schedule gets close to equal.
Does 50/50 mean no support?	No. With equal overnights the higher earner still pays, unless incomes are also equal.
Can a business owner hide income in the business?	Not legally. Business income is counted under a statutory formula whether or not it is distributed (Minn. Stat. 518A.30; Haefele v. Haefele, Minn. 2013).
What if a parent quits or works part time?	The court assigns potential income, at least 30 hours a week at minimum wage, and usually more (Minn. Stat. 518A.32).
When does it end?	At 18, or when the child finishes high school if later, but not past 20. Longer for a child who cannot support themselves because of a disability.
Can we change it ourselves?	No. Only a court order changes support. Side deals are unenforceable (Lee v. Kalis, Minn. 2025).
What if I don’t pay?	Income withholding, tax refund intercept, driver’s and occupational license suspension, passport denial, liens, contempt with possible jail, and criminal nonsupport charges up to a felony (Minn. Stat. 609.375).

What Child Support Is in Minnesota

Child support is a court-ordered monthly payment from one parent to the other for the financial care of their child. Every child in Minnesota has the right to be supported by both parents, whether or not the parents were married, lived together, or ever got along. The obligation is the same in a divorce, a custody case between unmarried parents, and a paternity action brought by the county.

A Minnesota support order has three separate parts, and the order must list each one as its own dollar amount (Minn. Stat. 518A.34(h)). Basic support covers housing, food, clothing, transportation, education costs and the other ordinary expenses of raising a child. Medical support covers the cost of health and dental coverage for the child and how unreimbursed medical bills are split. Child care support covers work-related or school-related daycare. When people say “child support” they usually mean basic support, but the other two can add hundreds of dollars a month, so do not ignore them.

Who can ask for child support

Either parent can ask. So can a grandparent or other relative who has custody of the child. The county child support agency can also start a case, and it will when the parent with the child applies for child support services or receives public assistance such as MFIP or Medical Assistance. In that situation the county is a party to the case whether the parents like it or not, because the state is partly paying for the child.

If the parents were never married, support can be ordered once paternity is established, either by a signed Recognition of Parentage or by a court order. A Recognition of Parentage is enough to set support. It is not enough to give the father custody or parenting time; that takes a separate court order, which I cover in my guide to fathers’ rights and paternity.

Obligor and obligee

You will see two words in every order and every county letter. The obligor is the parent who pays. The obligee is the parent who receives. Under the current formula either parent can end up as the obligor, including the parent who has the children most of the time, if that parent earns a lot more than the other one. There is also a presumption that a parent with more than 55 percent of the court-ordered parenting time owes no basic support (Minn. Stat. 518A.26, subd. 14), although the other parent can try to rebut it.

How Child Support Is Calculated in Minnesota

Minnesota uses what is called the income shares model. The idea is that a child should get the same share of the parents’ combined income that the child would have received if the parents lived together. The court follows the six steps in Minn. Stat. 518A.34, and the state calculator does the same six steps in the same order.

Step	What the court does	Statute
1	Finds each parent’s gross monthly income.	518A.29, 518A.30, 518A.32
2	Subtracts a credit for any nonjoint children each parent supports. The result is each parent’s parental income for determining child support, which everyone calls PICS.	518A.33
3	Adds the two PICS figures together and works out each parent’s percentage of the combined total.	518A.34(b)(3)
4	Looks up the combined basic support obligation for that combined income and the number of children on the guidelines table.	518A.35
5	Multiplies the table amount by each parent’s percentage to get each parent’s share.	518A.34(b)(5)
6	Runs the parenting expense adjustment, a formula based on each parent’s court-ordered overnights, which decides who pays and how much basic support.	518A.36
Then	Adds child care support and medical support, and checks the self-support reserve for a low-income obligor.	518A.40, 518A.41, 518A.42

Here is the single most useful thing I can tell you about the formula. Steps 1 and 6 are where the real money is. The table and the percentages are arithmetic; nobody argues about them. Fights happen over what a parent’s income really is, especially when one parent is self-employed or has stopped working, and over how many overnights the order gives each parent. Those two questions get their own sections below.

If you just want a number right now, my free Minnesota child support calculator is fast and easy: it uses the same guidelines table the courts use and shows the math step by step. For every input, including child care and medical, the state’s official Minnesota Child Support Calculator is the full version, and in my experience it lands within a few dollars of what a judge will order when the inputs are right. Getting the inputs right is the hard part.

What Counts as Income for Minnesota Child Support

Gross income under Minn. Stat. 518A.29 means any form of periodic payment to a person, before taxes. The list is long on purpose: salary, wages, commissions, bonuses, self-employment income, workers’ compensation, unemployment benefits, annuity payments, military and naval retirement, pension and disability payments, Social Security and VA benefits, and spousal maintenance received. If you get it regularly, assume it counts. In 26 years I have watched judges err on the side of counting income, not excluding it.

Perks and in-kind benefits

The statute also counts employee benefits in kind, or in lieu of cash, if they reduce your personal living expenses. A company car you drive on weekends, a housing allowance, a paid cell phone, a steady meal allowance: all of it can be added to income because it frees up cash you would otherwise spend. A work truck you could not reasonably use for anything but work is a different story. I go through the common ones in In-Kind Payments and Child Support in Minnesota.

Overtime and second jobs

Overtime counts. There is a narrow exception for pay from work beyond 40 hours a week, but every one of these must be true: the extra work started after the case was filed (or after the existing order, on a modification), it is voluntary and not a condition of the job, it is hourly overtime or a part-time second job, the pay structure was not rearranged to game support, and the parent is already paying at least the guideline amount on their regular income. A parent in arrears must use the net overtime to pay down the arrears. In practice the exception helps the parent who picked up a second job after the divorce to make ends meet. It does not help the parent who has always worked 55 hours a week.

What does not count

Public assistance based on need does not count: MFIP, general assistance, SNAP, SSI and similar programs. Child support a parent receives for a different child does not count either. Spousal maintenance a parent pays under a court order is subtracted from that parent’s income, and maintenance received is added to the other parent’s.

Other children you support

If you support children from another relationship, Minn. Stat. 518A.33 gives you a credit before the percentages are calculated. Court-ordered support you actually pay for a nonjoint child comes straight off your gross income. If the other child lives with you and there is no order, the credit is 75 percent of what the guidelines table would show for your income alone and that number of children, up to six. Having a new baby after an order is entered is not, by itself, grounds to modify the existing order, but the credit is applied if the order is modified for some other reason.

Social Security and VA benefits paid for the child

If a child receives Social Security or apportioned VA benefits because of a parent’s disability or retirement, the benefit is counted as that parent’s income and, if the other parent receives it for the child, it is subtracted from the paying parent’s obligation (Minn. Stat. 518A.31). Since January 1, 2025, a lump sum of those benefits received before a modification motion can be applied to arrears for the months it covers, as long as the benefit was not already built into the earlier order.

Child Support for Business Owners and the Self-Employed

If either parent owns a business, farms, works as an independent contractor or holds shares in a family company, this is the section to read twice. Business cases are the ones that go to trial, because a W-2 tells you what someone earns and a Schedule C or a K-1 only tells you what they reported.

The statutory formula, not the tax return

Under Minn. Stat. 518A.30, income from self-employment or from operating a business, including joint ownership of a partnership or a closely held corporation, is gross receipts, minus cost of goods sold, minus the ordinary and necessary expenses required to run the business. That sounds like the tax return, but it is not the tax return. The statute specifically excludes the accelerated component of depreciation, investment tax credits, and any other expense the court decides is inappropriate or excessive for child support purposes. And the burden is on the person claiming the expense to prove it was ordinary and necessary if it is challenged.

What that means in a courtroom: the taxable income on the return is the starting point, not the answer. The other side’s lawyer, and often the judge, will add back the things the IRS lets a business deduct that do not actually cost the owner anything in cash, and the personal expenses that got run through the business.

Common add-backs	Why they get added back
Section 179 and bonus depreciation	The accelerated portion is excluded by statute. A $90,000 combine written off in one year did not cost $90,000 of income that year.
Personal vehicle, fuel and insurance	If the truck goes to the lake on weekends, part of it is personal living expense, which is income in kind.
Cell phone, internet, home office	Same logic. The business paying your personal bills reduces your living expenses.
Meals, travel and entertainment	Deductible for taxes, often not “required” for the business under 518A.30.
Wages to a new spouse or a child	Scrutinized if the work does not match the pay.
Retained earnings and undistributed profit	Counted as the owner’s income in proportion to ownership, whether or not distributed (see Haefele, below).
Owner draws and distributions	Not income by themselves; they are how the owner takes out income that is already counted. Counting both would double count.

The Haefele rule: it does not matter what you actually took out

In Haefele v. Haefele (Minn. 2013), the Minnesota Supreme Court settled the biggest question in business-owner cases. A mother owned 20 percent of a closely held S corporation. The company’s profits passed through to her tax return, but much of the money stayed in the company or went to a related investment entity, and part of what she received just covered the tax on income she never saw. She argued only the cash she actually got should count. The Supreme Court said no. Gross income from a shareholder’s interest in a closely held S corporation is calculated under the statutory formula in 518A.30, in proportion to the owner’s share, and it does not depend on how much was distributed or available to the parent.

The practical consequences are large. A minority owner in the family business can be assigned income the family patriarch never lets her touch. An owner who leaves profit in the company to buy equipment has that profit counted anyway. The court can still look at the whole picture when it sets the final number, and a deviation is possible, but the starting income is the formula number, not the cash. I wrote about the decision when it came out in Child Support and Minnesota Business Owners.

Farms

Farm income is self-employment income, and farms are the hardest business cases I handle. Income swings with prices and weather, depreciation on equipment is enormous, government payments and crop insurance show up some years and not others, and family land is often rented from a parent at a price that would not survive an arm’s length test. Judges in southern Minnesota see a lot of farm cases and generally average income over three to five years, add back accelerated depreciation, and look hard at related-party rent and wages. If you farm, bring the Schedule F for five years, the depreciation schedules, and the FSA and crop insurance records. If you are the other parent, ask for them in discovery and get an accountant who knows farms.

What the other side’s lawyer will ask for

Expect to produce three to five years of business and personal tax returns with every schedule, K-1s, profit and loss statements, balance sheets, general ledgers, bank and credit card statements for the business, and loan applications. The loan applications matter more than people expect. An owner who told the bank the business nets $180,000 a year has a hard time telling a judge it nets $60,000. Where the numbers are big or the books are messy, one side or both hires a forensic accountant, which in my experience starts around $20,000 and is only worth it when real money is at stake.

When low business income is real

The statute protects an honest downturn. A self-employed parent is not treated as voluntarily underemployed if net income dropped because of economic conditions tied directly to that line of work (Minn. Stat. 518A.32, subd. 6). Low milk prices, a lost contract, a construction slowdown: those are defensible if you can document them. What is not defensible is the owner who cut his own salary the month the divorce was filed while the business kept paying his truck, his phone and his boat.

Imputed Income: When a Parent Is Unemployed or Underemployed

The second place child support cases get fought is over a parent who is not earning what they could. Minnesota calls this potential income, and lawyers call it imputed income. The rule in Minn. Stat. 518A.32 is simple to state: if a parent is voluntarily unemployed, underemployed, or working less than full time, or there is no direct evidence of income at all, support must be calculated on what that parent could be earning. The court does not have discretion to skip this step. It is rebuttably presumed that every parent can work full time, which means 40 hours a week unless the trade customarily works more or less.

The three ways a court sets potential income

Method	How it works	When it is used
1. Probable earnings	What the parent would likely earn based on employment potential, recent work history and occupational qualifications, in light of prevailing jobs and pay in the community.	The usual method for a parent with a work history. The last real job is the starting point.
2. Benefits received	Actual unemployment or workers’ compensation benefits.	A parent who is on those benefits.
3. Minimum wage floor	30 hours a week at 100 percent of the current federal or state minimum wage, whichever is higher.	A parent with no useful work history, or when nothing better is proved.

Older articles, including one of mine from 2012, describe the floor as full time at 150 percent of minimum wage. The legislature changed it in 2015 to 30 hours at 100 percent, which at Minnesota’s large-employer minimum wage comes to roughly $1,500 a month. Judges rarely stop at the floor for a parent who has ever held a real job.

When a parent is not considered voluntarily underemployed

The statute lists the defenses, and the parent raising one has to prove it. The situation is temporary and will lead to higher income, such as a parent finishing a nursing degree. It is a bona fide career change whose benefit outweighs the effect of the lower income on the child. The parent is physically or mentally incapacitated, or incarcerated. Or a government agency has found the parent eligible for general assistance or SSI. No potential income is imputed to a parent receiving MFIP or TANF cash assistance.

A stay-at-home parent caring for the child who is the subject of the order gets a separate analysis under subdivision 5. The court looks at how the parents handled work and child care before the case, the parent’s employment history and what jobs are available, whether child care and commuting would eat up most of the pay, the child’s age and health, and whether child care is even available. That protection does not apply to a parent who stays home only to care for children from another relationship.

How this plays out in real cases

The classic fact pattern is the parent who quits a $65,000 job and takes a part-time position for $20,000 a few months before, or a few months after, the case is filed. The timing is what judges notice. I have had judges impute the full old salary when the resignation came out of nowhere and no job search followed, and I have had judges accept a real pay cut when the parent was laid off, applied for 40 jobs, and documented it. The difference was the evidence. If your income has dropped, keep every application, every interview, every rejection email, and the doctor’s note if health is involved. If you are the parent on the other side, ask in discovery for the separation paperwork, the job search records and the new employer’s pay records, and consider a vocational evaluation if real money is at stake.

A few things I tell clients that surprise them. A parent who was fired for cause is usually treated as voluntarily unemployed. A parent who refuses available overtime that the job normally includes can have it counted. A parent who chooses a lower-paying job closer to the kids has a decent career change argument, and a parent who left a job to follow a new partner across the country usually does not. And the court can impute income to the receiving parent too, not just the paying parent, which changes the percentages and therefore the support amount.

How Much Is Child Support for One, Two or Three Kids in Minnesota?

The guidelines table in Minn. Stat. 518A.35 gives the combined basic support obligation for every $100 of combined parental income from $1,400 to $20,000 a month. These are the actual table figures, not estimates. Remember that the table amount is the total both parents are responsible for; it is split by income percentage and then adjusted for overnights, so the check one parent writes is always less than the table figure.

Combined monthly income (PICS)	One child	Two children	Three children
$0 to $1,399	$50	$60	$70
$2,000	$170	$200	$235
$3,000	$415	$525	$598
$4,000	$625	$845	$954
$5,000	$818	$1,132	$1,281
$6,000	$988	$1,383	$1,577
$7,000	$1,044	$1,462	$1,666
$8,000	$1,106	$1,548	$1,765
$10,000	$1,230	$1,722	$1,963
$12,000	$1,354	$1,895	$2,160
$15,000	$1,539	$2,155	$2,457
$20,000 and over (cap)	$1,839	$2,575	$2,935

Two things jump out of the table. First, support rises steeply up to about $6,000 of combined income and then flattens, because the table is built on what families at each income level actually spend on children. Second, two children do not cost twice one child. At $6,000 the second child adds about $400, not another $988, because housing and transportation serve the whole household. To see where your family lands, plug your own numbers into the child support calculator.

The $20,000 income cap

Parents whose combined income is above $20,000 a month are treated as if they earned $20,000: one child is $1,839, two children $2,575, three children $2,935, before the split and the overnight adjustment. A court may go above the cap only on findings that the child has a disability or another substantial, demonstrated need and that the extra support will directly benefit the child (518A.35, subd. 3). In high-income cases the fight is usually not about the table at all; it is about private school, activities, cars and college, which Minnesota does not require either parent to pay for absent an agreement.

Worked Examples With Real Numbers

These examples apply the statutory table and the overnight formula in 518A.36 exactly as written. They cover basic support only, before medical and child care support, and the overnights are the paying parent’s court-ordered overnights per year. Run your own numbers in the state calculator before you rely on anything.

How much child support will I pay if I make $1,000 a week?

$1,000 a week is about $4,333 a month gross. Say the other parent earns $3,000 a month and you have one child. Combined income is $7,333, the table amount is $1,063, and your share is 59 percent, or $628.

Your court-ordered overnights	Typical schedule	Basic support you pay
52 (14 percent)	Every other weekend	about $623
91 (25 percent)	The statutory minimum presumption	about $591
104 (28 percent)	Every other weekend plus a midweek overnight	about $565
146 (40 percent)	Extended weekends plus summer	about $385
182 (50 percent)	Week on, week off or 2-2-5-5	about $101

How much child support will I pay if I make $2,000 a week?

$2,000 a week is about $8,667 a month. With the other parent at $4,000 and one child, combined income is $12,667, the table amount is $1,391, and your share is 68 percent, or $952. With every other weekend (52 overnights) you pay about $945. With 104 overnights, about $869. With an equal schedule, about $262, because your income is more than double the other parent’s.

A modest-income example

Parents earning $3,500 and $2,500 a month with one child have a combined income of $6,000 and a table amount of $988. The higher earner’s share is 58 percent, $576, and with every other weekend the payment is about $572. At this income the self-support reserve described below does not apply, but it would if the paying parent earned closer to $2,000.

Parenting Time and the Overnight Formula

The parenting expense adjustment in Minn. Stat. 518A.36 is the law’s way of recognizing that a parent who has the child overnight is buying food, paying for a bedroom and driving to practice during that time. Three rules matter more than the math.

First, it is court-ordered overnights that count, not the schedule you actually follow. If the order says every other weekend and you have informally moved to week on, week off, the formula still uses every other weekend until the order is changed. I see this constantly, and it cuts both ways: the parent paying too much because the order is stale, and the parent who has quietly reduced the other parent’s time but is still getting credit for it. If there is no parenting time order at all, there is no adjustment.

Second, the formula is not a straight line. The court cubes each parent’s annual overnights, weights each by the other parent’s share of the combined obligation, and divides. Because the overnights are cubed, going from 52 overnights to 104 barely moves the number, while going from 146 to 182 moves it a lot. Look at the $1,000-a-week table above: doubling overnights from 52 to 104 saved $58 a month, and the last 36 overnights saved $284. The 2016 legislature designed it this way to end the old fights over whether a parent was at 45 or 45.1 percent. The formula has been in effect since August 1, 2018 and has not changed since.

Third, overnights are counted over a two-year average, and the court can count overnight equivalents for a parent who has significant daytime periods with a young child but no overnights. That comes up with infants and with parents who work nights.

Do I Pay Child Support With 50/50 Custody in Minnesota?

Yes, in most cases. Equal parenting time does not mean no child support. With equal overnights the formula reduces to a simple rule: the higher earner pays half of the difference between the two parents’ shares of the table amount. Basic support is zero only when parenting time is equal and incomes are also equal, and even then the court can order support if the child’s expenses are not actually being shared equally (518A.36, subd. 3). My child support calculator shows the 50/50 math with your own incomes.

Parents are often surprised that the amount is this small, and the receiving parent sometimes feels cheated. The logic is that both households are now running a full-time home for the child, so the transfer only needs to even out the income gap. If you are negotiating a 50/50 schedule mainly to reduce child support, know two things: judges can tell, and the savings are smaller than most people expect until the incomes are far apart.

The Minnesota Child Support Calculator and Worksheet

The fastest way to get a number is my free Minnesota child support calculator, which uses the same guidelines table and overnight formula the courts use and shows the math step by step. For every input, including child care and medical, the state’s official Minnesota Child Support Calculator is the full version, and it is also free. In the state tool you enter each parent’s gross monthly income, the number of joint children, any nonjoint children, each parent’s overnights, the cost of the children’s health and dental coverage and who pays it, and work-related child care costs. It applies 518A.34 through 518A.42 and prints a worksheet you can attach to a motion. Most counties expect to see that worksheet with any child support filing.

The calculator is only as good as its inputs, and three inputs are judgment calls it cannot make for you. It does not decide what a business owner’s income really is. It does not decide whether a parent is voluntarily underemployed or what to impute. And it uses the overnights you type in, which should be court-ordered overnights, not the schedule you wish you had. When two parents get wildly different results from the same calculator, one of those three inputs is almost always the reason.

In my experience the final order in a typical case lands within a few dollars of the calculator. Minnesota judges take the guidelines seriously, and a deviation requires written findings. If the number feels wrong, the fix is usually in the income or overnight inputs, not in arguing with the formula.

Medical Support and Child Care Support

Medical support

Every support order must address health coverage for the child under Minn. Stat. 518A.41. If the child is already covered on an appropriate plan, the parent providing it keeps providing it. If only one parent has appropriate coverage available, that parent is ordered to carry it. If both do, the parent the child lives with carries it unless the parties agree otherwise or the other parent’s plan is clearly better. Public coverage such as Medical Assistance is presumed appropriate. Private coverage is presumed affordable if the child’s share of the premium is no more than 5 percent of the parents’ combined income, and it must be accessible, which generally means primary care within 30 minutes or 30 miles of the child’s home.

The cost of the child’s portion of the premium is divided between the parents in proportion to income, and the parent who does not carry the plan pays their share as part of monthly support. Unreimbursed and uninsured expenses, meaning deductibles, copays, orthodontia, glasses, counseling and the like, are also split by income percentage, but they are not part of the monthly amount. The order says how they are split and the parents settle up as bills come in, which is a frequent source of friction. Keep receipts, send them promptly, and put the request in writing.

Child care support

Work-related or education-related child care costs are divided by income percentage under Minn. Stat. 518A.40, after a reduction for the estimated federal and state child care tax credits the custodial parent will receive. The court requires proof of employment or school attendance and documentation of the actual cost, and if costs vary by season the court uses a monthly average. A low-income obligor pays no more than the co-payment they would owe under the state’s child care assistance program. Child care support is child support, so it can be enforced like the rest, but it is not subject to cost-of-living adjustments.

Child care is the most changeable piece of an order. Daycare ends when kindergarten starts, summer care appears and disappears, a parent changes jobs. Any substantial change in child care costs is a ground to modify, and the paying parent is entitled to annual verification from the provider.

What about extracurricular activities, phones and cars?

Basic support is meant to cover ordinary expenses, including activities. Minnesota law does not require a separate contribution for hockey, dance or a first car unless the parents agree to one, and many do, in writing, as part of a stipulation. I explain the common arrangements in Does Child Support Mean Paying for Extracurricular Activities?

Low-Income Parents: The Self-Support Reserve and Minimum Support

A support order should not exceed the paying parent’s ability to pay. Under Minn. Stat. 518A.42, the court subtracts a self-support reserve equal to 120 percent of the federal poverty guideline for one person from the obligor’s income. If what is left is less than the guideline support amount, the court reduces the order, cutting medical support first, then child care support, then basic support, until the order fits within the available income.

If what is left is at or below the minimum, or the obligor’s gross income is under 120 percent of the poverty guideline, the court orders the minimum basic support: $50 a month for one child, $60 for two, $70 for three, $80 for four, $90 for five and $100 for six or more. A parent paying the minimum is presumed unable to pay child care or medical support. The minimum does not apply to an obligor who is incarcerated, who receives general assistance, SSI, TANF or MFIP, or whom the court finds has no income and no ability to earn any.

When a Judge Can Deviate From the Guidelines

The guideline amount is presumed correct. A court can order more or less, but only with written findings explaining why the guideline amount would be unjust or inappropriate and what the court ordered instead. The factors are in Minn. Stat. 518A.43: each parent’s complete financial picture, including property; the child’s extraordinary needs; the standard of living the child would have had if the parents lived together; a child living abroad in a much cheaper or more expensive country; which parent claims the child for taxes and what that is worth; certain debts; and whether the obligor’s total support exceeds the federal withholding limits.

Two deviations come up often. Under subdivision 1a, where a parent has between 10 and 45 percent of the parenting time and the income gap is so large that making that parent pay would hurt the child, the court can order no basic support. And under subdivision 1b, on a modification where the only change is that the custodial parent now earns more and support would go up, the court can decline the increase. The court may not deviate just because the parents share joint legal custody, and it may not deviate downward in a public assistance case without finding extreme hardship.

Deviations are the exception. In 26 years the overwhelming majority of my orders have been at the guideline amount, and the ones that were not had specific, documented reasons.

Cost-of-Living Adjustments

Every Minnesota support order must include a cost-of-living clause under Minn. Stat. 518A.75. Every two years the amount goes up with the consumer price index unless the obligor contests it in time, typically on the ground that their own income has not kept up. For cases paid through the county, the adjustment takes effect May 1 and the obligor must get notice at least 20 days ahead. A court can waive the clause if the obligor’s job does not give cost-of-living raises or the order already has step increases. A bill to end automatic adjustments (HF 2456 / SF 2666) did not pass, so the clause still applies in 2026. The details, including how to contest an adjustment, are in Cost of Living Adjustment in Minnesota (COLA).

How a Child Support Case Moves in Minnesota

Child support is set in one of three kinds of cases. In a divorce, it is one part of the decree, decided along with custody, parenting time and property. Between unmarried parents it is set in a custody and parenting time case, or in a paternity action. And in a large share of cases it is set or enforced by the county child support agency in what Minnesota calls a IV-D case, named for the federal law that funds it.

The county and the expedited process

When a parent applies for child support services from the county, or receives public assistance, the county becomes a party and the case goes through the expedited child support process under Minn. Stat. 518A.46 and the rules in Minn. Gen. R. Prac. 351 to 379. These hearings are run by a child support magistrate rather than a district judge, they move faster, and county staff who are not lawyers can prepare the paperwork and appear. A magistrate’s order can be reviewed by a district judge on a timely motion. The county does not represent either parent; it represents the public interest in getting support set and paid. If you want someone on your side in that hearing, you bring your own lawyer.

The county charges modest fees for full services, and most orders are paid through the state’s payment center so there is a record. I generally recommend keeping a IV-D case open even when the parents get along, for one reason: it creates the official record that protects both of you. The next section shows what happens when parents close the county case and go it alone.

Temporary support and retroactivity

Support can be ordered on a temporary basis early in a divorce or custody case and adjusted in the final order. In a paternity case the court can also order past support for up to two years before the action was started, and reimbursement of pregnancy and confinement expenses. Once an order exists, it is only changed going forward from the date a modification motion is served, which brings us to modification.

How to Modify Child Support in Minnesota

Either parent, or the county, can ask to change support under Minn. Stat. 518A.39. The test is a substantial change in circumstances that makes the existing order unreasonable and unfair. The statute lists the usual changes: a substantial increase or decrease in either parent’s income, a change in the child’s or a parent’s needs, receipt of public assistance, a change in the cost of living, extraordinary medical expenses, a change in health coverage or its cost, new or changed child care costs, and the emancipation of a child.

The 20 percent and $75 rule

A change is presumed substantial, and the existing order is presumed unfair, if running the current guidelines on today’s numbers produces an amount at least 20 percent and at least $75 a month higher or lower than the current order. Other presumptions: a parent’s gross income has dropped at least 20 percent through no fault or choice of their own, the medical support terms cannot be enforced, the ordered health coverage is no longer available, or the order states support as a percentage rather than a dollar figure. A new child born after the order is not, by itself, a reason to modify.

The process and how long it takes

You file a motion in the court that issued the order, with a financial affidavit, proof of income and a calculator worksheet showing the proposed amount, and you serve the other parent and the county if it is involved. The other parent responds with their own numbers. If the case is a IV-D case the hearing is before a child support magistrate; otherwise a district judge, who need not hold an evidentiary hearing and may decide on the papers. An uncontested modification in most Minnesota counties takes about 60 to 90 days from filing to a new order. A contested one, especially one with a business or an imputed income fight, takes three to six months or more. My article What Happens If You or Your Ex’s Income Changes After Divorce? covers what to gather before you file.

Modifications are not retroactive before service

This rule costs people more money than any other in this guide. A modification can only go back to the date the motion was served on the other parent (and on the county, in a public assistance case). If you lost your job in January and serve a motion in July, the court cannot reduce support for January through June, no matter how sympathetic the facts. Each unpaid monthly installment became a judgment by operation of law on the day it was due. File the month your circumstances change. If you cannot afford a lawyer, the court’s self-help forms are enough to get a motion served and stop the bleeding.

Side deals do not count: Lee v. Kalis

Parents regularly agree between themselves to lower support, often with good intentions and a Venmo history to prove it. The Minnesota Supreme Court closed that door for good in Lee v. Kalis (Minn. 2025), a Le Sueur County case. The parents closed their county case, agreed informally to drop support from $1,145 to $1,000 and later to $500 a month, and paid by Venmo for years. When the mother reapplied for county services, the county calculated arrears against the original order: over $30,000. The Supreme Court held that a private agreement to modify child support is invalid, only a court can change an order, and only from the date a motion is served. I get a call about one of these roughly once a month. The answer is always the same: the arrears are owed, and the money spent fighting it would have been better spent on a motion years earlier. The full story is in Side Deals, Venmo and $30,000 Regret.

When one child ages out

If the order states a specific amount per child, support for a child ends automatically when that child is emancipated. If it states one amount for several children, which is how most orders read, the full amount continues until the youngest child is emancipated unless someone brings a motion. The remaining obligation is recalculated on current incomes, not just reduced by a fraction, and because two children do not cost twice one child, the drop is smaller than parents expect. File when the oldest child graduates; the reduction is not retroactive either.

When Child Support Ends in Minnesota

Under Minn. Stat. 518A.26, subd. 5, a child for support purposes is someone under 18, or under 20 who is still attending secondary school, or someone who because of a physical or mental condition is incapable of self-support. So support ends at 18 unless the child is still in high school, in which case it continues until graduation or the 20th birthday, whichever comes first. A child who turns 18 in March of senior year is supported through graduation in June. A child who drops out at 18 is emancipated. Support can also end earlier if a child marries, enlists in the military, or is otherwise emancipated by court order.

Minnesota does not require either parent to pay for college. Parents can agree to in a stipulation, and those agreements are enforceable as contracts, but a judge will not impose a college obligation. For a child with a disability who cannot support themselves, support can continue indefinitely, but it is not automatic; the parent seeking it must bring a motion with medical evidence. I covered the common surprises in I Thought Child Support Ended at Age 18 and When Is My Child No Longer a Child?

Arrears do not end when the child does. Past-due support is a judgment that survives emancipation, and income withholding continues until it is paid in full. The county will keep collecting from a 45-year-old parent for a 25-year-old child.

What Happens If You Don’t Pay Child Support in Minnesota: Penalties and Enforcement

Minnesota has one of the most aggressive child support enforcement systems in the country, and most of it runs automatically through the county without anyone going to court. Every unpaid installment becomes a judgment against you by operation of law on the day it is due (Minn. Stat. 548.091, subd. 1a). The tools escalate as the arrears grow, and most of them key off one number: how many months of support you are behind. Here is the whole list, with the thresholds from the statutes.

Enforcement tool	Trigger	What happens	Statute
Income withholding	Every order, from day one	Support is taken from your paycheck and sent to the state payment center. If you are behind, an extra 20 percent of the monthly amount is withheld toward arrears. Employers who ignore the notice face a $500 fine and contempt.	518A.53
Tax refund intercept	Arrears of $150 or more in public assistance cases, $500 in other cases (federal); state refunds and lottery winnings are intercepted too	Your federal and Minnesota refunds go to the arrears before you see them.	Federal offset program; Minn. Stat. 270A
Driver’s license suspension	Arrears of 3 times your monthly obligation and no approved payment agreement	90 days’ notice, 30 days to request a hearing, then suspension. A limited license is possible but expires after 90 days.	518A.65
Occupational license suspension	Arrears of 3 times your monthly obligation	Nursing, contractor, real estate, teaching and other licenses can be suspended. A lawyer is reported to the Lawyers Board.	518A.66
Motor vehicle lien	Judgment arrears of 3 times your monthly obligation	A lien on the title of any vehicle in your name, so you cannot sell or borrow against it.	518A.67
Recreational license suspension	Arrears of 6 times your monthly obligation, after other tools have failed	No hunting or fishing license.	518A.68
Passport denial	Arrears of $2,500 or more	The State Department refuses to issue or renew your passport until the arrears are resolved.	42 U.S.C. 652(k)
Credit bureau reporting	Arrears	Reported to the credit bureaus and shows on your report.	42 U.S.C. 666(a)(7)
Bank account seizure	Arrears, through the financial institution data match	The county matches your name against bank records and can freeze and take money from your accounts, including retirement funds.	13B.06, 518A.46, subd. 3
Liens and judgments	Each missed payment	The judgment attaches to real estate you own, and lump sums such as a settlement, a workers’ compensation award or lottery winnings can be intercepted.	548.091, 518A.46, subd. 3
Seek-employment order	Arrears of 3 times monthly and no verified job	The court orders you to look for work and report at least five applications a week. Ignoring it is evidence of willful nonpayment.	518A.64
Public name list	Arrears of $10,000 or more, no payments in 12 months, cannot be located	The state may publish your name, photo and amount owed.	518A.74
Civil contempt	Arrears of 3 times monthly and no payment plan	A hearing where you must explain why you have not paid. Possible jail, usually stayed on conditions; or up to 32 hours a week of community service for six weeks.	518A.71, 518A.72, ch. 588
Criminal nonsupport	Knowing failure to pay; charges escalate with time and amount	Misdemeanor, gross misdemeanor or felony. See below.	609.375

Can you go to jail for not paying child support in Minnesota?

Yes, two different ways, and it helps to understand the difference.

The first is civil contempt. Once you are three months behind and not on an approved payment plan, the county or the other parent can bring a contempt motion under Minn. Stat. 518A.72. The order itself is treated as evidence that you can pay, and failing to pay is treated as evidence of contempt, so the burden is on you to show you could not comply. If the court finds you could have paid and did not, it can sentence you to jail under chapter 588, up to six months, but in practice judges almost always stay the jail time on the condition that you make a purge payment or follow a payment plan. The point of civil contempt is to get the money, not to punish, and a parent who starts paying usually never sees a cell. A parent who shows up with no job, no job search and a new truck sometimes does.

The second is criminal nonsupport under Minn. Stat. 609.375, which is a real criminal charge brought by the county attorney, with a criminal record if you are convicted. Knowingly failing to pay court-ordered support is a misdemeanor, up to 90 days in jail and a $1,000 fine. It becomes a gross misdemeanor, up to 364 days and $3,000, if the nonpayment goes on for more than 90 days but not more than 180 days, or if the arrears reach six times your monthly obligation. It becomes a felony, up to two years in prison and a $5,000 fine, if nonpayment goes on for more than 180 days or the arrears reach nine times your monthly obligation. On a $700-a-month order, nine times is $6,300. The county must have tried to hold you in contempt first before charging you criminally, and it is an affirmative defense if you prove you had a lawful excuse for not paying. Nonpayment while on probation after a felony conviction is itself a probation violation.

A separate federal crime, the Deadbeat Parents Punishment Act (18 U.S.C. 228), applies when the child lives in another state: a misdemeanor for willfully failing to pay for more than a year or owing more than $5,000, and a felony for more than two years or more than $10,000, or for crossing state lines to avoid paying. Federal prosecutions are rare and reserved for large, deliberate cases, but they happen. I wrote about one international version in Child Support, Fastballs and International Law.

Interest on arrears

Minnesota used to charge interest on child support judgments, and old arrears balances often doubled over the years. That ended. Since August 1, 2022, no interest accrues on any past, current or future child support judgment (Minn. Stat. 548.091, subd. 1a). Interest that accrued before that date is still owed, but the balance stops growing. If you see interest being added to a Minnesota child support balance today, ask the county to explain it.

Arrears never go away on their own

Child support arrears are not discharged in bankruptcy. They are not wiped out when the child turns 18. They are not forgiven because the other parent informally agreed to less, as Lee v. Kalis made painfully clear. The county can collect for decades, and the only ways a balance goes down are paying it, a court order correcting an error, or, in public assistance cases, the county agreeing to compromise its own share under its arrears management programs. The other parent can agree to forgive arrears owed to them, but not arrears assigned to the state.

If You Can’t Pay, or You Aren’t Being Paid

If you cannot pay

The worst thing you can do is nothing. Every month you wait is a month the court cannot reach back to. If your income has dropped, serve a motion to modify the same month, using the court’s self-help forms if you have to. Call the county child support office before they call you and ask about a written payment agreement under Minn. Stat. 518A.69; an approved agreement is what stops the license suspensions and the contempt motion, and the statute requires the county to tailor it to what you can actually pay. Pay something every month even if it is less than the order, because a record of partial payments is the difference between a judge who sees a parent in trouble and a judge who sees a parent who quit. And keep every piece of paper that shows why you cannot pay: the layoff notice, the medical records, the job applications.

If you are not being paid

Apply for full child support services from your county if you have not already. The county has tools you do not: income withholding at a new employer within days of a new-hire report, the tax intercept, license suspensions, the bank match. It costs little and it does most of the work. If you have a county case and nothing is moving, a contempt motion by your own lawyer gets the other parent in front of a judge faster than the county’s queue, and the court can order the other parent to pay your attorney fees. Keep your own ledger of what was ordered and what was paid; the county’s records are usually right, but not always. My older article Minnesota Child Support Order Enforcement walks through the first steps.

Child Support and Taxes

Child support is not deductible by the parent who pays it and is not taxable income to the parent who receives it. That is different from spousal maintenance, which for divorces finalized before 2019 is deductible and taxable, and for later divorces is neither.

The tax issue that matters is who claims the child. Federal law gives the dependency and child tax credit to the custodial parent, meaning the parent the child lived with more nights, unless that parent signs IRS Form 8332 releasing the claim. Minnesota courts can and often do allocate the claim in a support order, for example alternating years or giving it to the paying parent as long as support is current, and the value of the claim is a deviation factor under 518A.43. If the order is silent, the IRS rule controls. My 2013 article on dependency exemptions predates the 2018 federal tax changes; the child tax credit replaced the exemption, but the allocation question is the same.

Do You Need a Child Support Lawyer?

When you probably don’t

If both parents have W-2 jobs, the parenting time order is clear, nobody owns a business and nobody has quit work, the calculator will produce the number a judge would order and the county can get it done. A simple modification when a child ages out or daycare ends is also within reach of the court’s self-help forms. I tell people this on the phone regularly; it is not worth paying me $500 an hour to get the same number the calculator gives you for free.

When you do

You need a lawyer when income is the fight: a business, a farm, a professional practice, commissions, a parent who stopped working or took a pay cut, a parent whose employer pays for half their life. You need one when overnights are in dispute, because the parenting time order drives the formula and that order is set in the custody case, not the support case. You need one when arrears are large, a contempt motion or criminal charge is on the table, or a license is about to be suspended. And you need one before you sign a stipulation, because a support term you agree to is very hard to undo, and I have seen too many parents agree to numbers built on the other parent’s version of their income.

Frequently Asked Questions About Minnesota Child Support

How is child support calculated in Minnesota?

Minnesota uses the income shares model in Minn. Stat. 518A.34. The court adds both parents’ gross monthly incomes, looks up the combined basic support amount on the guidelines table in 518A.35, divides it between the parents in proportion to income, and then applies a formula based on each parent’s court-ordered overnights. Medical support and child care support are added separately.

How much is child support for one child in Minnesota?

The combined basic support obligation for one child runs from $50 a month at the lowest incomes to $1,839 a month when combined parental income is $20,000 or more. At $6,000 of combined income it is $988. That total is split by income share and reduced for the paying parent’s overnights, so the actual payment is lower.

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

Usually yes. With equal overnights the higher earner pays half the difference between the two parents’ shares of the table amount. For example, parents earning $7,000 and $4,000 a month with one child and equal time produce a payment of about $176 a month from the higher earner. Support is zero only if both time and income are equal.

How does Minnesota calculate child support for a business owner?

Business income is gross receipts minus cost of goods sold minus ordinary and necessary business expenses, under Minn. Stat. 518A.30. Accelerated depreciation and personal expenses run through the business are added back, and the owner has the burden of proving a challenged expense was necessary. Under Haefele v. Haefele (Minn. 2013), an owner’s share of a closely held company’s income counts whether or not it was distributed.

What is imputed income for child support in Minnesota?

If a parent is voluntarily unemployed, underemployed or working less than full time, the court calculates support on potential income under Minn. Stat. 518A.32: the parent’s probable earnings based on work history and qualifications, actual unemployment or workers’ compensation benefits, or at minimum 30 hours a week at minimum wage. Exceptions cover temporary situations that will raise income, a bona fide career change, incapacity or incarceration, and parents on MFIP or SSI.

When does child support end in Minnesota?

At 18, or if the child is still in high school, when the child graduates or turns 20, whichever comes first. Support ends earlier if the child marries, enlists or is emancipated by a court, and it can continue indefinitely for a child who cannot support themselves because of a disability. Minnesota does not require parents to pay for college. Unpaid arrears survive emancipation.

How do I modify child support in Minnesota?

File and serve a motion under Minn. Stat. 518A.39 showing a substantial change in circumstances. A change is presumed if the guidelines on current numbers produce an amount at least 20 percent and at least $75 a month different from the current order. The new amount can only go back to the date the motion was served, so file as soon as circumstances change. Private agreements to change support are not enforceable.

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

Income withholding plus 20 percent toward arrears, federal and state tax refund intercepts, driver’s and occupational license suspension at three months of arrears, recreational license suspension at six months, passport denial at $2,500, credit reporting, bank account seizure, liens, contempt of court with possible jail, and criminal nonsupport charges under Minn. Stat. 609.375 that rise to a felony after 180 days of nonpayment or arrears of nine times the monthly obligation.

Can you go to jail for child support in Minnesota?

Yes. Civil contempt can result in jail, usually stayed if the parent follows a payment plan. Criminal nonsupport under Minn. Stat. 609.375 carries up to 90 days for a misdemeanor, 364 days for a gross misdemeanor, and two years in prison for a felony, which applies after more than 180 days of nonpayment or arrears equal to nine times the monthly support amount.

Does child support accrue interest in Minnesota?

Not anymore. Since August 1, 2022, no interest accrues on Minnesota child support judgments. Interest that accrued before that date is still owed.

What is the new child support law in Minnesota?

There is no new formula for 2026. The guidelines table, the overnight formula and the 120 percent self-support reserve are unchanged. Effective January 1, 2025, Social Security or VA benefits paid for the child because of the paying parent’s disability can be applied to arrears on a modification. Effective August 1, 2026, a parent filing for divorce must notify the county child support agency if either spouse receives public benefits. Claims of a 2025 change to the parenting time thresholds or a 130 percent self-support reserve are not in the statute.

What income counts for child support in Minnesota?

Under Minn. Stat. 518A.29, gross income includes wages, salary, commissions, bonuses, overtime, self-employment and business income, workers’ compensation, unemployment, Social Security and VA benefits, pensions, disability payments, spousal maintenance received, and employer-paid perks that reduce living expenses. It excludes need-based public assistance such as MFIP and SSI, and child support received for another child.
