Mississippi calculates child support using a statutory guideline that starts with each parent’s gross income and then applies deductions allowed by law. The guideline takes into account combined parental income, each parent’s share of that income, and the number of children. Courts then consider parent-time and additional documented expenses for healthcare or childcare to arrive at a baseline amount. The guideline provides a structured starting point to promote consistency across cases while allowing courts to consider family-specific factors. When the guideline amount does not fairly reflect a child’s needs or parental circumstances, parties may request a deviation supported by evidence. Common deviation reasons include extraordinary medical expenses, unusually high childcare costs, or disproportionate living expenses due to custody arrangements. Presenting complete financial records and credible documentation at hearing helps the court decide whether a deviation is warranted and to set an order that balances the child’s needs with each parent’s ability to pay.
