How South Dakota Calculates Child Support

South Dakota calculates child support using the Income Shares Model as defined in SDCL §25-7-6.1. Both parents' net incomes are combined to determine the total support obligation from the state schedule. Each parent's share is then allocated proportionally based on their percentage of the combined net income.

South Dakota uses net income rather than gross income, meaning all mandatory deductions including federal income taxes, Social Security, and Medicare are subtracted before the calculation. Health insurance premiums for the child, childcare costs, and extraordinary medical expenses are added to the base obligation. South Dakota also maintains a self-support reserve of $1,015 per month (2024).

Parenting time adjustments are available when the non-custodial parent has significant overnight parenting time. Extraordinary medical expenses not covered by insurance are shared proportionally between the parents.
