How North Dakota child support law works

Legal starting point. North Dakota Administrative Code chapter 75-02-04.1 uses the obligor’s net income and a child-count schedule. The state’s calculation is custody-sensitive: the ordinary primary-residential-responsibility calculation is different from extended, equal, or split-responsibility cases. Read North Dakota Administrative Code 75-02-04.1.

How the guideline is calculated

The base worksheet converts annual net income to monthly net income, rounds it under the rule, and selects the support amount for the number of children. Multiple families, parenting-time adjustments, deductions, benefits, and rebuttal factors require the full North Dakota analysis.

What this site’s worksheet covers

Uses North Dakota HHS Child Support Guidelines Calculator workbook updated January 1, 2026 and N.D. Admin. Code ch. 75-02-04.1, effective July 1, 2023. Worksheet 2 converts total annual net income to monthly net income, rounds the monthly figure to the nearest $100, caps the lookup at $25,000, and applies the child-count column in the guidelines table. N.D. Admin. Code § 75-02-04.1-10 determines the child support amount from the obligor’s monthly net income and the number of children for whom support is sought. This base module assumes the ordinary primary-residential-responsibility scenario. Multiple families, extended parenting time, foster care, split/equal residential responsibility, deductions/tax derivation and rebuttal factors require the full North Dakota worksheet/calculator.

Before you enter your numbers

Why does North Dakota ask about more than one year of business income?

North Dakota has specific net-income rules for self-employment, including treatment of fluctuating earnings and business records. A recent monthly draw does not necessarily measure guideline income. The ordinary obligor-income schedule must also be distinguished from equal residential responsibility or extended-parenting calculations.

Prepare this: Gather complete tax returns and business schedules for the relevant years, not only recent bank transfers. Keep the residential-responsibility order with the income calculation.

Read the relevant official instructions: North Dakota Administrative Code 75-02-04.1.

These preparation notes explain one part of the state guideline. A new estimate does not change an existing order; a modification request does.

How North Dakota cases actually get to a number

Convert to monthly net income as the guidelines define it, select the table amount for the number of children, and apply the remaining guideline steps. North Dakota’s official calculator is the practical reference for a filing.

North Dakota uses a monthly net-income table through the HHS calculator framework. The table amount is allocated according to the guidelines’ income-shares structure. That is a different path from neighboring states that use another model, so do not import a table, percentage, or overnight credit from somewhere else.

Parenting time in North Dakota

Equal residential responsibility has a specific North Dakota treatment. A primary-residential table result should not be halved because the parents ‘switch weeks.’

Costs North Dakota usually treats separately

  • Child-care costs
  • Health-insurance premiums
  • Uninsured medical expenses
  • Other guideline add-ons

When North Dakota courts leave the guideline

The table is presumptive. High income, subsistence needs, and a child’s special needs are deviation or adjustment facts. Imputed income is a frequent North Dakota dispute in seasonal work.

Questions specific to North Dakota

Is North Dakota a percentage-of-payer state?

No. It uses a net-income table and guideline allocation.

Seasonal oilfield or farm income?

Average it according to the guidelines and evidence. A single high month is a poor annual figure.

Equal parenting time?

Use the equal-residential-responsibility path, not a homemade 50 percent cut.
