How is child support calculated in Mississippi?
Mississippi simplified its income tax beginning in 2023 and continued reducing rates: 4.7% in 2024, 4.4% in 2025, and 4.0% effective January 1, 2026, applied to income over $10,000. The first $10,000 is exempt, effectively creating a zero bracket that benefits lower-income filers.
Mississippi has no state minimum wage law, so the federal minimum of $7.25/hr applies. The state has no local income taxes, disability insurance, or paid family leave programs.
Mississippi's 7% state sales tax is one of the highest in the nation. Groceries are taxed at a reduced rate of 5% under recent legislation, down from the full rate.
Mississippi provides a generous personal exemption of $6,000 for single filers ($12,000 married) in addition to the standard deduction, helping to lower the effective tax burden for lower-income residents.
Mississippi has some of the lowest property taxes in the South at approximately 0.65%. Homestead exemptions apply to the first $7,500 of assessed value for owner-occupied residences.

Mississippi child support — frequently asked questions
How is child support calculated?
Most states use the income shares model, which estimates what parents would have spent on the child if they lived together, then divides that based on each parent's income share. Factors include gross income, number of children, custody arrangement, and healthcare/childcare costs.
Can child support be modified?
Yes. Either parent can request a modification if there is a substantial change in circumstances, such as a significant income change (increase or decrease), job loss, change in custody arrangement, or changes in the child's needs.
At what age does child support end?
In most states, child support ends at age 18 or high school graduation (whichever comes later). Some states extend support to age 19-21 or through college. Court orders may specify different end dates based on individual circumstances.
