The South Dakota Child support law Code 25-7-6 mentions using the Income Shares Method on the net income of parents for computing the child support amount.

• The support amount will be estimated, taking into account the income earned by the parents and the parenting time spent by each parent.
• The state court has stipulated a basic amount as child support, and the health care and education expenses will be compound.
• Further, the child’s financial conditions, independent financial resources, will also be looked into while determining the child support amount.
• The support will extend until the child reaches eighteen or completes high school education, whichever is earlier.
