Utah Child Support Calculations Explained

When Utah parents separate or divorce, determining how child support will be calculated is one of the most important financial and legal steps in protecting a child’s wellbeing. Utah law requires both parents to contribute to the support of their children, but the exact amount each parent must pay depends on a detailed formula based on income, custody time, and other relevant factors.

Understanding how this formula works and how the court applies it helps parents plan realistically for their financial responsibilities and make informed decisions during the process.

How Utah’s Child Support System Works

Utah follows a structured approach to child support, guided primarily by the Utah Child Support Act and the Office of Recovery Services (ORS) guidelines. The model is designed to ensure children receive consistent financial support from both parents, reflecting what would have been available if the family had remained together.

Key factors courts consider

The gross monthly income of both parents

The number of children being supported

The custody arrangement (sole, joint, or split custody)

Healthcare, childcare, or insurance costs paid for the children

Certain deductions, such as alimony paid from a prior case or support for other dependents

The state provides standard child support worksheets that calculate payment amounts based on these variables. These worksheets are required for every divorce or custody case involving children and form the baseline for any court-ordered support.

Step-by-Step: How Utah Courts Calculate Support

1

Determine Income for Each Parent

Both parents must provide complete financial disclosure. Income can include wages, salaries, bonuses, commissions, and certain non-traditional earnings like freelance or self-employment income.

2

Apply the Custody Type

Utah distinguishes between three custody categories:

  • Sole custody: One parent has the child for more than 225 nights per year.
  • Joint custody: Each parent has at least 111 nights per year.
  • Split custody: Each parent has physical custody of at least one child.

Each category has its own worksheet, which adjusts the support amounts accordingly.

Use the Utah Child Support Guidelines Table

Once income and custody are known, the court refers to the state’s support schedule, which lists recommended support amounts based on combined parental income.

4

Adjust for Additional Expenses

Medical insurance premiums, uninsured medical costs, and work-related childcare expenses can all modify the base calculation. Courts may also consider education or transportation expenses when appropriate.

Common Mistakes Parents Make

Failing to update income: If one parent’s income changes substantially, child support should be reviewed and possibly modified.

Not accounting for health insurance: Premiums and uncovered medical costs affect the calculation and fairness.

Ignoring custody time changes: Shifts in parenting schedules should be reflected in support amounts.

Using unofficial calculators: Many tools do not reflect Utah’s latest updates or ORS tables. Use the official worksheets or consult an attorney.

Modification and Enforcement

Utah law allows parents to request a modification of child support if circumstances have changed such as a new job, job loss, remarriage, or a major shift in custody. The requesting parent must show a significant and continuing change, often at least a 10% difference in the current order amount.

Enforcement is handled through the Office of Recovery Services (ORS), which can collect overdue support through wage garnishments, tax refund interceptions, or license suspensions if necessary.

Key Utah Statutes

Child support is primarily governed by Utah Code Title 81, Chapter 6, which outlines how payments are calculated, enforced, and modified. It also details how parents share medical and childcare expenses and defines “gross income.” For direct reference, see Utah Code § 81-6-101, which provides the foundational rules used by the courts and the Office of Recovery Services.
