revise the child support obligation schedule.

HB 1040 revises South Dakota's child support calculation schedule to adjust the percentage of a noncustodial parent's net income required for child support based on income levels and number of children. It introduces a $871 monthly self-support reserve, protecting low-income parents from excessive payments by comparing their obligation to a proportional share calculated using both parents' incomes. The bill also requires incarcerated parents serving over 180 days to pay at least the minimum base amount specified in the schedule. This directly affects noncustodial parents across all income brackets, particularly those with lower earnings or who are incarcerated.
