Mississippi calculates child support by using statutory guidelines that consider both parents’ incomes, the number of children, and custody or parenting time arrangements. Courts review gross incomes, allowable deductions, and additional expenses such as health insurance or childcare. Judges apply the guideline formula to determine a base obligation and may adjust for extraordinary expenses or shared costs. Accurate income documentation such as paystubs and tax returns is important to ensure the calculation reflects actual earnings and results in a fair order under state law. If either parent has complex income sources such as self-employment, bonuses, or irregular payments, the court will examine additional records to determine consistent income. Imputing income may occur if a parent is voluntarily underemployed. Understanding how the guideline operates helps parents anticipate likely results and prepare documentation that supports their position during negotiation or hearing.
