Mississippi calculates child support using a percentage-of-income model under Miss. Code § 43-19-101, requiring non-custodial parents to pay 14% of their adjusted gross income for one child, 20% for two children, 22% for three children, 24% for four children, and 26% for five or more children. Unlike the 41 states using the income shares model, Mississippi considers only the non-custodial parent's earnings when determining child support obligations. The Mississippi Department of Human Services (MDHS) collects over $300 million annually in child support payments, and support continues until the child reaches age 21—one of only a few states extending support beyond age 18.

How Mississippi Calculates Child Support Payments
Mississippi courts calculate child support in three steps: determine gross income from all sources, subtract allowable deductions to reach adjusted gross income, then multiply by the statutory percentage based on the number of children. This percentage-of-income model makes Mississippi one of only nine states that does not consider the custodial parent's earnings in the base calculation.
Step 1: Determine Gross Income
Gross income under Mississippi law includes all potential sources reasonably expected to be available to the non-custodial parent. Under the guidelines, gross income encompasses wages, salary, commissions, bonuses, independent contractor compensation, workers' compensation benefits, disability payments, unemployment benefits, annuity payments, retirement benefits including IRA distributions, Social Security benefits, dividends, interest income, rental income, and any other payments from individuals or entities.
Step 2: Calculate Adjusted Gross Income
Miss. Code § 43-19-101(3) permits four categories of deductions from gross income:
- Federal, state, and local income taxes (actual withholding amounts)
- Social Security contributions (FICA)
- Mandatory retirement and disability contributions (not voluntary 401(k) contributions)
- Pre-existing child support obligations ordered by another court
Voluntary deductions such as 401(k) contributions, health insurance premiums for the parent only, and union dues are not automatic deductions under Mississippi's child support calculation. Courts require documented proof of all claimed deductions through pay stubs, tax returns, or existing court orders.
Step 3: Apply the Statutory Percentage
After subtracting allowable deductions, divide the annual adjusted gross income by 12 to determine the monthly figure. The court then multiplies this monthly adjusted gross income by the appropriate percentage:
| Number of Children | Percentage of Adjusted Gross Income |
|---|---|
| 1 child | 14% |
| 2 children | 20% |
| 3 children | 22% |
| 4 children | 24% |
| 5 or more children | 26% |
Example Calculation
For a non-custodial parent earning $60,000 gross annual income with $15,000 in allowable deductions:
- Annual adjusted gross income: $45,000
- Monthly adjusted gross income: $3,750
- One child (14%): $525 per month
- Two children (20%): $750 per month
- Three children (22%): $825 per month
How Much Is Child Support in Mississippi for Different Income Levels
Mississippi child support amounts vary directly with income since the state applies fixed percentages to adjusted gross income rather than using complex formulas. Courts must make written findings when the non-custodial parent's annual adjusted gross income falls below $10,000 or exceeds $100,000, as these income levels trigger mandatory deviation analysis under Miss. Code § 43-19-103.
Low-Income Considerations (Under $10,000 Annual AGI)
When a non-custodial parent earns less than $10,000 in annual adjusted gross income, Mississippi courts must evaluate whether applying the standard percentages would leave the parent unable to meet basic subsistence needs. A parent earning $800 monthly ($9,600 annually) would theoretically owe $112 per month for one child at 14%, but courts may reduce this amount if the payment would render the parent unable to maintain housing, food, or transportation necessary for employment.
Middle-Income Calculations ($30,000-$75,000 Annual AGI)
| Monthly Adjusted Gross Income | 1 Child (14%) | 2 Children (20%) | 3 Children (22%) |
|---|---|---|---|
| $2,500 ($30,000 annual) | $350 | $500 | $550 |
| $4,000 ($48,000 annual) | $560 | $800 | $880 |
| $5,000 ($60,000 annual) | $700 | $1,000 | $1,100 |
| $6,250 ($75,000 annual) | $875 | $1,250 | $1,375 |
High-Income Considerations (Over $100,000 Annual AGI)
For non-custodial parents earning more than $100,000 annually, courts must make written findings addressing whether the guideline amount exceeds the children's reasonable needs. A parent earning $150,000 annually would owe approximately $1,750 monthly for one child under strict guideline application ($150,000 × 14% ÷ 12), but courts may cap support at levels reflecting reasonable child-rearing costs rather than providing windfall benefits.
Health Insurance and Medical Expenses in Mississippi Child Support
Mississippi courts must address health insurance and medical expenses as part of every child support order, with specific statutory requirements under Miss. Code § 43-13-303 governing insurance enrollment and enforcement. When health insurance is available to either parent at reasonable cost, courts typically order that parent to provide coverage and adjust the child support amount accordingly.
Health Insurance Cost Allocation
Courts consider the actual cost of adding the child to an existing policy when determining whether coverage is available at reasonable cost. If a parent can add the child to employer-provided insurance for $150 monthly but the standalone marketplace policy would cost $450 monthly, courts typically order the employer-covered option and factor that expense into the support calculation.
Uninsured Medical Expenses
Mississippi child support orders routinely address unreimbursed medical, dental, vision, and psychological expenses. Courts commonly order parents to split these expenses proportionally based on income or equally at 50% each. Extraordinary medical expenses—such as ongoing therapy, orthodontia, treatment for chronic conditions, or specialized educational services—may be allocated separately from base support rather than folded into the percentage calculation.
Insurance Enrollment Enforcement
Under Mississippi law, health insurers and employers must honor court orders requiring dependent coverage. Employers cannot disenroll a child unless the court order is no longer in effect, the child will be covered by another insurer, or the employer has eliminated family coverage for all employees. Premiums may be withheld directly from the obligor's wages alongside child support payments.
When Mississippi Courts Deviate from Child Support Guidelines
Mississippi's child support guidelines create a rebuttable presumption that the calculated amount is correct, but courts may deviate when applying the standard formula would be unjust or inappropriate under Miss. Code § 43-19-103. Any deviation requires written findings explaining why the guidelines were not applied and specifying how the ordered amount differs from the presumptive calculation.
Factors Supporting Upward Deviation
- Extraordinary medical, psychological, or dental expenses beyond routine care
- Special educational needs requiring private schooling or specialized programs
- Work-related childcare expenses enabling the custodial parent's employment
- High cost-of-living in the child's geographic area
- Established lifestyle requiring maintenance for the child's stability
- Non-custodial parent's failure to exercise visitation, leaving all expenses with custodial parent
Factors Supporting Downward Deviation
- Extended parenting time with the non-custodial parent exceeding standard visitation
- Child's independent income from employment, trust funds, or other sources
- Spousal support (alimony) paid by the obligor to the custodial parent
- Seasonal or irregular income making strict percentage calculation inequitable
- Non-custodial parent's disability or chronic illness affecting earning capacity
- Existing support obligations for other children not included in current case
Shared Custody Adjustments
Mississippi has no statutory formula for shared custody adjustments, leaving modifications entirely to judicial discretion. When parents share roughly equal parenting time, courts may reduce the non-custodial parent's obligation to reflect the increased direct expenses that parent incurs during their parenting time. However, courts do not automatically offset support 50/50 when physical custody is equally divided.
Mississippi Child Support Enforcement Methods
The Mississippi Department of Human Services Division of Child Support Enforcement (MDHS-CSE) collects over $300 million annually through escalating enforcement mechanisms. Parents can apply for enforcement services through MDHS for a $25 application fee plus $35 annual fee, or recipients of public assistance receive services automatically.
Automatic Income Withholding
Most Mississippi child support orders include immediate income withholding, requiring employers to deduct support from each paycheck and remit payment to the State Disbursement Unit. Under Miss. Code § 43-19-201, employers who willfully fail to withhold face penalties up to $500, or up to $1,000 if collusion with the employee is proven.
Wage Garnishment Limits
Federal law caps child support garnishment at:
- 50% of disposable earnings if currently supporting another spouse or child
- 60% of disposable earnings if not supporting another spouse or child
- Additional 5% if arrearages exceed 12 weeks
Additional Enforcement Tools
| Enforcement Method | Trigger | Consequence |
|---|---|---|
| Tax refund intercept | Any arrearage | Federal and state refunds seized |
| Credit bureau reporting | 60+ days delinquent | Negative credit impact |
| Driver's license suspension | Court order | Cannot renew until compliant |
| Professional license revocation | Court order | Cannot practice profession |
| Passport denial | Arrearage exceeds $2,500 | Cannot obtain or renew passport |
| Property liens | Court order | Cannot sell property until satisfied |
| Contempt of court | Willful non-payment | Up to 6 months incarceration |
Making Payments
All payments should be made to MDHS/SDU (State Disbursement Unit), not directly to the custodial parent. Payments made directly to the other parent will not be credited to the account, potentially resulting in arrearages and enforcement actions despite actual payments made. Send payments to: MDHS/SDU, P.O. Box 23094, Jackson, MS 39225.
Modifying Mississippi Child Support Orders
Mississippi allows modification of existing child support orders when a material change in circumstances occurs under Miss. Code § 93-11-65. Either parent may petition the chancery court that issued the original order, or modifications can be processed through MDHS for cases within the child support enforcement system.
Qualifying Changes for Modification
- Income change of 25% or greater for either parent (some courts apply 15% threshold)
- Job loss, disability, or serious illness affecting earning capacity
- Change in the number of children requiring support
- Significant change in the child's needs (medical condition, educational requirements)
- Change in custody or parenting time arrangements
- Incarceration of the non-custodial parent
Three-Year Review Right
Parents have the right to request a child support review every three years from the date of the original order or last modification without proving a substantial change in circumstances. Reviews requested within the three-year window require proof of material change, while three-year reviews do not.
Voluntary Income Reduction
A voluntary reduction in income is not a substantial change of circumstances justifying modification. Courts will impute income to parents who voluntarily quit jobs, take lower-paying positions, or become underemployed without legitimate reason. The modification must result from unforeseen circumstances, not strategic choices to reduce support obligations.
Retroactive Modifications
Mississippi courts generally cannot retroactively modify child support before the date a modification petition was filed. Arrearages that accrued before filing remain due regardless of changed circumstances. Parents experiencing income loss should file for modification immediately rather than waiting and accumulating arrearages.
When Mississippi Child Support Ends
Mississippi child support obligations terminate when the child reaches age 21 or becomes emancipated, whichever occurs first, under Miss. Code § 93-11-65(a). This makes Mississippi one of only a few states where support extends beyond age 18, reflecting the state's age of majority being 21 rather than 18.
Emancipation Events
Child support terminates upon any of the following emancipation events:
- Child reaches age 21
- Child marries
- Child joins the military and serves on a full-time basis
- Child is convicted of a felony and sentenced to 2+ years incarceration
- Child discontinues full-time school enrollment after reaching age 18 (unless disabled)
- Child voluntarily moves out, obtains full-time employment, and does not continue education
Disabled Adult Children
Support obligations may continue beyond age 21 for adult children who became physically or mentally disabled before reaching the age of majority and cannot financially support themselves. Courts evaluate disability on a case-by-case basis, considering the child's capacity for self-support.
Termination Procedure
The paying parent must continue making payments until a court issues an order terminating the support obligation. Stopping payments before obtaining a termination order may result in arrearages, enforcement actions, and contempt charges even if the child has technically reached emancipation. File a motion to terminate support before the anticipated termination date to ensure a smooth transition.
Filing for Child Support in Mississippi
Parents can establish child support orders through either the county chancery court or the Mississippi Department of Human Services (MDHS). The chancery court path provides more control over the process but requires either self-representation or attorney fees, while MDHS offers free or low-cost services but may process cases more slowly.
Chancery Court Filing
Filing fees range from $150 to $200 depending on the county. As of March 2026, verify exact fees with your local chancery clerk's office. Parents who cannot afford the filing fee may submit a Pauper's Affidavit requesting a fee waiver. Required documents typically include:
- Complaint for Child Support or Petition to Establish Paternity and Child Support
- Financial declaration or income affidavit
- Child Support Worksheet (Form 12.5.2)
- Birth certificates for children
- Proof of income (pay stubs, tax returns, W-2 forms)
MDHS Child Support Services
Parents who do not receive public assistance can apply for MDHS support services by paying a $25 application fee and $35 annual fee. MDHS assists with establishing paternity, locating absent parents, establishing support orders, modifying existing orders, and enforcing support obligations. Parents receiving TANF, Medicaid, or SNAP automatically receive child support services at no cost.
Residency Requirements
Under Miss. Code § 93-5-5, at least one parent must have been a bona fide resident of Mississippi for six months immediately preceding the filing. There is no separate county residency requirement—only the six-month state residency must be met. Cases may be filed in the county where either parent resides if both are Mississippi residents.
Frequently Asked Questions
How much is child support in Mississippi for one child?
Mississippi requires non-custodial parents to pay 14% of their adjusted gross income for one child under Miss. Code § 43-19-101. For a parent with $4,000 monthly adjusted gross income, child support would be $560 per month. Courts may deviate from this percentage when annual income falls below $10,000 or exceeds $100,000.
Does Mississippi consider both parents' income for child support?
No, Mississippi uses the percentage-of-income model which considers only the non-custodial parent's adjusted gross income, making it one of only nine states that does not use the income shares approach. The custodial parent's income is not factored into the base child support calculation, though it may be considered during deviation analysis.
How long does child support last in Mississippi?
Mississippi child support continues until the child reaches age 21 or becomes emancipated, whichever occurs first under Miss. Code § 93-11-65. This is longer than most states where support ends at 18 or 19. Emancipation can occur earlier through marriage, full-time military service, felony incarceration, or voluntary independent living.
Can child support be modified in Mississippi?
Yes, either parent can petition for modification when a material change in circumstances occurs, such as a 25% or greater income change, job loss, disability, or change in the child's needs. Parents also have the right to request a review every three years without proving a substantial change. Modifications take effect from the filing date, not retroactively.
What happens if child support is not paid in Mississippi?
Mississippi enforces child support through wage garnishment (up to 65% of disposable income), tax refund intercept, driver's license suspension, professional license revocation, credit bureau reporting, property liens, passport denial for arrearages over $2,500, and contempt of court with potential incarceration up to 6 months. MDHS collects over $300 million annually through these mechanisms.
Does shared custody reduce child support in Mississippi?
Mississippi has no statutory formula for shared custody adjustments, leaving reductions entirely to judicial discretion under Miss. Code § 43-19-103. When parents share roughly equal parenting time, courts may reduce support to account for the non-custodial parent's increased direct expenses, but there is no automatic 50/50 offset built into the calculation.
Are health insurance costs included in Mississippi child support?
Health insurance costs are addressed separately from the percentage-based support calculation under Miss. Code § 43-13-303. Courts typically order the parent with more affordable coverage to provide insurance and may adjust support accordingly. Unreimbursed medical expenses are usually split between parents, either equally or proportional to income.
What income counts toward child support in Mississippi?
Mississippi child support guidelines include all potential income sources: wages, salary, commissions, bonuses, self-employment income, workers' compensation, disability benefits, unemployment, retirement benefits, Social Security, dividends, interest, rental income, and any other payments. Allowable deductions include federal and state taxes, Social Security contributions, mandatory retirement contributions, and pre-existing child support orders.
Can I get child support without going to court in Mississippi?
Yes, the Mississippi Department of Human Services (MDHS) can establish child support orders administratively for a $25 application fee plus $35 annual fee. MDHS services include locating absent parents, establishing paternity, calculating support amounts, and issuing administrative orders. However, contested cases or those requiring judicial discretion for deviation from guidelines typically require chancery court involvement.
How is imputed income calculated in Mississippi?
When a parent is voluntarily unemployed or underemployed, Mississippi courts may impute income based on earning capacity using factors such as work history, education, job skills, health, and local job market conditions. Courts frequently use median income data for the parent's occupation or minimum wage earnings as a baseline. Voluntary income reduction does not justify support modification.
