§ How North Dakota calculates support

North Dakota uses a percentage-of-income approach under N.D. Admin. Code ch. 75-02-04.1 applied to the obligor's adjusted net income (gross income minus hypothetical federal/state income tax, FICA/Medicare, union dues, health insurance, and court-ordered support for other children). A guideline schedule sets the base obligation by income and number of children — commonly expressed as about 14% (1 child), 19% (2), 22% (3), 24% (4), 25% (5), 26% (6+), decreasing at higher incomes and capped at $25,000 monthly net. The child's actual health insurance and work-related childcare are added on top; parenting-time and self-support adjustments also apply.

How to open or modify a case in North Dakota

  1. Apply to Child Support (within the Department of Health and Human Services) or file directly with the court.
  2. Establish parentage if needed.
  3. Use the official online Guidelines Calculator / worksheet, entering gross income, taxes, deductions, and number of children.
  4. The court enters a support order based on the guidelines (a rebuttable presumption).
  5. Orders are reviewed periodically — every 18 months for TANF/foster cases or full-service cases, otherwise a parent may request review or file a motion after 18 months.
  6. To modify, request a review or file a court motion showing a substantial change in circumstances (an order less than 85% of the guideline amount triggers agency action).

Illustrative examples

Illustrative example
Illustrative example — two children, primary custody to other parent

Scenario: Obligor's adjusted net income is about $4,000/month, two children.

Walk-through: Using the guideline schedule's approximate 19% rate for two children: 19% × $4,000 = $760/month base, before adding the child's health insurance and work-related childcare.

Takeaway: North Dakota applies a percentage of the obligor's adjusted net income; actual health and childcare costs are added on top.

Illustrative example
Illustrative example — equal residential responsibility

Scenario: Parents share 50/50 overnights. Parent A adjusted net $5,000 (would owe ~$700 for 1 child); Parent B adjusted net $3,000 (would owe ~$420).

Walk-through: Offset the two hypothetical obligations: $700 − $420 = $280/month paid by Parent A to Parent B.

Takeaway: In equal-residential-responsibility cases North Dakota offsets each parent's hypothetical obligation; the higher earner pays the difference.

? Frequently asked questions

Whose income is used in North Dakota?
The base calculation uses only the paying parent's adjusted net income. The receiving parent's income matters only in split/equal residential responsibility or when it is at least three times the obligor's.
What counts as income and what is deducted?
Income includes wages, overtime, bonuses, pensions, benefits, and net self-employment income. Deductions are hypothetical federal/state income tax, FICA/Medicare, union dues, health insurance, and existing child-support orders.
Is there a self-support reserve?
Yes. When the obligor's adjusted net income is very low, the formula adjusts so the obligation does not push the parent below basic living needs.
How does parenting time affect support?
An extended-visitation adjustment applies when the paying parent has more than 100 court-ordered overnights per year (Schedule D).
What if a parent is underemployed?
North Dakota presumes underemployment below the greater of 167× the federal minimum wage or 60% of statewide average earnings, and can impute income.
