Mississippi calculates child support using guideline worksheets that consider both parents’ gross income, the number of children, and allowable deductions such as health insurance premiums and childcare costs. Courts may also include extraordinary expenses like significant medical or educational costs when determining the final amount. The guideline provides a starting point, and judges can adjust support based on a child’s needs and each parent’s financial situation. Having accurate income documentation and records of expenses helps ensure the calculation reflects reality. If parties disagree on income or expenses, the court may order discovery to verify financial information, such as tax returns or employer statements. For self-employed parents, adjustments for business expenses and reasonable draws can affect the calculation. Presenting organized evidence at hearings helps the court reach a dependable support figure that is enforceable under Mississippi law.
