How is Child Support Calculated in Iowa?

Iowa uses a team approach for child support. The court first looks at what both you and the other parent earn together to decide on a total support amount. Your final share is then based on your slice of that combined income pie.

Understanding Iowa's Shared Custody Rules

When your child spends at least 128 nights per year with each parent, Iowa considers it 'shared physical care' and uses a special formula. This method increases the basic support amount and then adjusts each parent's share based on the percentage of time they care for the child.

Iowa Child Support: Frequently Asked Questions


At what age does child support end in IA?

In Iowa, child support typically ends when a child turns 18. However, if the child is still attending high school full-time, support will continue until they graduate or turn 19, whichever occurs first.



How is child support calculated if one parent is unemployed in IA?

If a parent is unemployed or underemployed by choice, the court can 'impute' income. This means support will be calculated based on what that parent has the potential to earn, considering their education, work history, and local job market.



How do I modify a child support order in IA?

You can request a modification if there is a 'substantial change in circumstances.' In Iowa, this is generally met if the new calculation shows the support amount would change by at least 10% from the current order.



Does IA child support cover college expenses?

Yes, Iowa courts have the authority to order parents to contribute to college costs in what is called a 'postsecondary education subsidy.' This support can continue until the child turns 22, depending on the parents' finances and other factors.



How does IA handle health insurance and childcare costs?

The costs for the child's health insurance premium and necessary work-related childcare are added on top of the basic support amount. These expenses are then divided between the parents in proportion to their share of their combined income.
