How Mississippi calculates child support
Mississippi uses the percentage of income model: child support is calculated as a set percentage of the paying parent's income, with the percentage increasing with the number of children.
Governing law: Miss. Code Ann. § 43-19-101 — Percentages apply to statutory 'adjusted gross income' (gross minus taxes and mandatory deductions) and are presumptive only for AGI between $10,000 and $100,000/yr.
Mississippi's guideline percentages of the paying parent's net income:
| Children | Percentage of income |
|---|---|
| 1 | 14% |
| 2 | 20% |
| 3 | 22% |
| 4 | 24% |
| 5 | 26% |
Frequently asked questions
How is child support calculated in Mississippi?
Mississippi uses the percentage of income model: child support is calculated as a set percentage of the paying parent's income, with the percentage increasing with the number of children. The guideline is set by Miss. Code Ann. § 43-19-101.
Is this the exact amount a Mississippi court will order?
No — this is a guideline estimate. Courts start from the guideline amount but can deviate for factors like extraordinary medical costs, special needs, other support obligations, or agreements between parents. For an official figure, consult your court’s self-help center or a family law attorney.
Does parenting time affect child support in Mississippi?
In most states, including under most guideline models, substantial parenting time (often above roughly 20–30% of overnights) reduces the paying parent's obligation. Our calculator applies a simplified parenting-time adjustment; Mississippi's courts apply their own specific rules, so treat shared-custody results as rough estimates.
What income counts for child support in Mississippi?
Generally all income: wages, self-employment, bonuses, commissions, and often investment income. Mississippi's guideline applies to net (after-tax) income — our calculator approximates net income from the gross figures you enter. Courts may also impute income to a parent who is voluntarily unemployed or underemployed.
