How North Dakota Calculates Child Support
North Dakota uses an obligor income model: only the paying parent's income counts.
- Start with the paying parent's total gross annual income.
- Subtract a hypothetical federal income tax (single filer, standard deduction), a hypothetical state income tax equal to 11% of the federal tax, FICA and Medicare, and the part of the health insurance premium that covers the children.
- Divide by 12 and round to the nearest $100 ($50 or more rounds up).
- Read the amount from the schedule for the number of children.
