Overview of North Dakota Child Support

North Dakota uses a straightforward Percentage of Income model under NDCC §14-09-09.7. Unlike most states that use the Income Shares Model, North Dakota calculates child support by applying a set percentage to the obligor parent's net income, with adjustments available for children from other relationships.

This approach makes North Dakota's child support calculations relatively simple and predictable. The percentage increases with the number of children, and there is no statutory income cap.

How Child Support Is Calculated in North Dakota

The North Dakota child support formula works as follows:

  1. Determine net monthly income: Start with gross income and subtract federal and state income taxes, Social Security, Medicare, health insurance for the child, and mandatory retirement contributions
  2. Apply the percentage based on the number of children
  3. Adjust for multi-family obligations if the parent has children from other relationships
  4. Consider the self-support reserve to ensure the obligor retains poverty-level income

Key Factors in North Dakota Calculations

Net Income Definition

North Dakota defines net income as gross income from all sources minus:

  • Federal and state income taxes
  • Social Security taxes
  • Medicare taxes
  • Health insurance premiums for the child
  • Mandatory retirement contributions

No Income Cap

Unlike many states, North Dakota does not have a statutory income cap. The percentage is applied to all of the obligor's net income regardless of how high it may be.

Adjustments for Other Children

If the obligor parent has children from other relationships that they are legally obligated to support, the percentage may be reduced. This multi-family adjustment ensures that all children receive fair support.

Low-Income Adjustments

Low-income obligors may qualify for a reduced obligation. The self-support reserve ensures that the obligor retains enough income at or above the poverty level to meet their own basic needs.

Minimum and Maximum Amounts

Minimum: North Dakota does not have a fixed statutory minimum, but the self-support reserve protects low-income obligors by ensuring they retain poverty-level income.

Maximum: There is no income cap in North Dakota. The percentage applies to all net income.

Modification and Enforcement

Modification

North Dakota allows modification when:

  • There has been a material change in circumstances
  • A significant change in the obligor's income has occurred
