Utah Child Support: The Complete Guide

Utah uses the Income Shares Model to calculate child support — one of the most widely adopted approaches in the United States. This model is based on the premise that children should receive the same proportion of parental income they would have received if their parents remained together. Both parents’ incomes are combined, a base obligation is determined from the state’s guidelines schedule, and each parent contributes proportionally based on their share of the combined income.

Having worked alongside Utah family law practitioners for many years analysing support calculations, I’ll walk you through exactly how the Utah child support calculator above works — and what factors courts consider beyond the basic formula.

Joint Custody & Overnights Adjustment

When the non-custodial parent has the child for 30% or more of the year (110 or more overnights), Utah applies a joint physical custody formula that credits the paying parent for the time the child spends with them. The adjusted obligation decreases as the overnights increase toward 50%. At true 50/50 custody, the higher-earning parent typically pays a reduced amount to the lower-earning parent rather than full standard support.

Additional Mandatory Add-Ons

Beyond the base obligation, Utah courts automatically add work-related childcare costs and health insurance premiums. These are allocated proportionally between the parents based on their income shares. If Parent 1 earns 60% of combined income and the monthly childcare cost is $500, Parent 1’s add-on share is $300. The Utah child support calculator above handles these add-ons automatically.

⚖️ Important: Utah defines gross income very broadly — it includes wages, salaries, bonuses, commissions, overtime, rental income, investment income, social security, disability payments, workers’ compensation, and unemployment benefits. Imputed income may apply if a court believes a parent is voluntarily underemployed.

Frequently Asked Questions

Yes. In Utah, child support orders can be modified when there has been a material change in circumstances — typically a change of 15% or more in either parent’s income, a change in the child’s needs, or a significant change in custody arrangements. Either parent can petition the court or the Utah Office of Recovery Services for a review every three years regardless of income changes.
In Utah, child support generally continues until the child turns 18. However, if the child is still enrolled in high school at 18, support continues until the child graduates or turns 19, whichever occurs first. Support can also continue beyond these ages for children with disabilities who cannot support themselves.
Utah’s Office of Recovery Services (ORS) enforces child support orders through wage garnishment, income tax refund interception, driver’s license suspension, passport denial, credit reporting, contempt of court proceedings, and in extreme cases, criminal prosecution. Utah takes child support enforcement very seriously.
In Utah, a new spouse’s income is generally not included in the child support calculation for the remarried parent. However, if the new marriage significantly changes the parent’s financial situation (such as enabling them to work more or less), the court may consider the overall financial picture. A new spouse’s income cannot be used to reduce the obligor’s support obligation.
