How Much Is Child Support in Mississippi? Percentages and Deviations

Child support in Mississippi is a flat percentage of the non-custodial parent’s adjusted gross income: 14% for one child, 20% for two, 22% for three, 24% for four, and 26% for five or more.¹ Mississippi uses a “percentage of obligor income” model, so only the paying parent’s earnings drive the calculation. The percentages are a rebuttable presumption, meaning a judge must apply them unless there’s a written reason to go higher or lower.

The Percentages by Number of Children

One child: 14%
Two children: 20%
Three children: 22%
Four children: 24%
Five or more children: 26%

The math is direct. A non-custodial parent with $4,000 in monthly adjusted gross income and two children owes $800 per month, or 20% of $4,000.¹

Two income ranges trigger extra scrutiny. If the paying parent earns less than $10,000 or more than $100,000 in adjusted gross income annually, the court has to make a written finding on whether the standard percentage is reasonable. For low earners, the judge looks at basic subsistence needs. For high earners, the judge has discretion to award more or less than the straight percentage. There is no automatic cap at $100,000; the court just has to explain itself in writing.¹

What Counts as Adjusted Gross Income

Everything hinges on the adjusted gross income figure, and Mississippi defines it broadly. The starting point sweeps in wages, salary, commissions, self-employment earnings, dividends and interest, trust income, workers’ compensation, disability payments, unemployment benefits, retirement payments, alimony received, and income from inherited property. One category is off the table: income from a new spouse or a second household is not counted.¹

From that gross total, the court subtracts a set list of items to reach the adjusted figure:

Federal, state, and local income taxes based on the parent’s actual tax liability, not the amount withheld from paychecks
Social Security contributions
Retirement or disability contributions that are required as a condition of employment (not voluntary)
Child support already being paid under an existing court order for other children

The annual adjusted total is divided by twelve to produce a monthly figure, and the appropriate percentage is applied to that.¹

If the Paying Parent Is Unemployed or Underemployed

Quitting a job or taking a lower-paying one doesn’t automatically produce a lower support number. Mississippi courts can impute income to a parent who is voluntarily unemployed or underemployed, meaning they assign an earning capacity based on what the parent could realistically make.

The imputed amount has to be tied to that specific parent’s circumstances rather than a flat default. Judges look at assets, job skills, education, age, health, criminal record, employment history, whether the parent has been actively job hunting, and the prevailing wages in the local market.¹

Reasons a Judge May Deviate from the Guideline Amount

Mississippi Code 43-19-103 lists ten factors that can push the support number above or below the guideline percentage. The judge has to put the reasoning in writing:

Extraordinary medical, psychological, educational, or dental expenses for the child
Independent income the child earns from a job or trust
The paying parent is also paying alimony to the same recipient
Seasonal income variations for either parent
The age of the child (older children often cost more)
Special needs the family has historically covered that exceed the guideline amount
Shared parenting arrangements, where substantial time with the non-custodial parent reduces the custodial parent’s costs, or where refusal of involvement increases them
Total assets of both parents and the child
Childcare costs the custodial parent incurs to work or because of a disability
Any other reasonable expense or debt needed for a fair result

Shared parenting is where most fights happen. A non-custodial parent who has the children a large portion of the year can argue that the straight percentage overstates what the custodial household actually spends, and the judge weighs both the time split and the real financial impact before adjusting.²

Health Insurance Is Part of the Order

Every Mississippi child support order has to address medical support. If the court directs a parent to carry health insurance for the child, the premium cost is folded into the overall arrangement. When the judge finds coverage isn’t available to either parent at a reasonable cost, that finding goes in writing and the order sets up an alternative way to cover the child’s medical expenses.³

Unreimbursed costs like deductibles, co-pays, dental work, vision care, and prescriptions are typically split between the parents. Most orders specify the split, often proportional to income.

How Long the Obligation Lasts

Child support in Mississippi does not end at 18. Unless the court order says otherwise, the duty to pay runs until the child turns 21. A few events cause earlier emancipation and end the obligation:

The child marries
The child joins the military full-time
The child is convicted of a felony and sentenced to two or more years of incarceration

A court can also find that emancipation has happened if a child who is at least 18 drops out of school full-time (unless disabled), voluntarily moves out to live independently while working full-time, or cohabits with someone without the paying parent’s approval.⁴

For a child with a physical or mental disability that existed during minority, support is presumed to continue past 21. The court can keep the obligation going, adjust custody, and account for public benefits the adult child receives when setting the amount. That presumption can be rebutted by showing the adult child is actually capable of self-support.⁵

Changing the Amount After the Order Is Entered

The guideline percentages apply to modifications the same way they apply to the original order. To get one, you generally have to show a material change in circumstances since the last order, such as a job loss, a substantial raise, a new medical condition, or a shift in custody. Timing matters: courts will not reduce support retroactively for any period before you actually file the request, so waiting costs money.

There is also a limit on how far back a custodial parent can reach for unpaid support. The non-custodial parent’s liability for past-due amounts is capped at one year before the date the enforcement lawsuit is filed.⁴

Until a judge signs a new order, the existing amount is what you owe. Cutting your own payments because you expect a modification is one of the fastest routes to a contempt finding.
