How Idaho Calculates Child Support

Idaho calculates child support using the Income Shares Model as defined in Idaho Code §32-706 and IRFLP Rule 126. Both parents' gross incomes are combined to determine the total support obligation from the state schedule. Each parent's share is proportional to their share of the combined income.

Health insurance premiums for the child and childcare costs are added to the basic obligation. Idaho provides shared custody adjustments and allows adjustments for children from other relationships. The self-support reserve of $1,012/month (2024) protects low-income obligors.

Courts may deviate from the guideline amount when applying the formula would be unjust. Factors considered include the child's special needs, the financial resources of both parents, and any extraordinary expenses related to the child's education or healthcare. Income may be imputed for voluntarily underemployed parents.

Frequently Asked Questions

How does Idaho calculate child support using the Income Shares Model?
Idaho uses the Income Shares Model under Idaho Code §32-706 and IRFLP Rule 126. Both parents' gross incomes are combined to determine the basic support obligation from the state schedule. Each parent then pays their proportional share based on their percentage of the combined income.
What is the self-support reserve in Idaho?
Idaho's self-support reserve is $1,012 per month (2024). This ensures the obligor parent retains enough income to meet their own basic living needs. If the parent's income is near this threshold, the court may reduce the support obligation.
What income is counted for Idaho child support?
Idaho counts gross income from all sources including wages, salaries, bonuses, commissions, self-employment income, interest, dividends, rental income, Social Security benefits, workers' compensation, and unemployment benefits. Idaho has a state income tax of up to 5.8%.
Does Idaho adjust support for shared custody?
Yes. Idaho provides shared custody adjustments when parents share significant parenting time. The adjustment accounts for the direct costs each parent incurs while the child is in their care, which can reduce the support obligation.
Can Idaho child support be modified?
Yes. Either parent can request a modification if there has been a material and substantial change in circumstances since the last order. This includes significant income changes, changes in custody or parenting time, or changes in the child's needs.
