Utah uses the Income Shares model (Utah Code § 81-6 (formerly § 78B-12)) to calculate child support. This model combines both parents' incomes to determine the total obligation, then divides it proportionally based on each parent's share.

Important Notes for Utah

  • Utah uses the Income Shares model, combining both parents' adjusted gross incomes to determine the total child support obligation.
  • Adjusted gross income is calculated by deducting one-half of self-employment taxes, alimony paid, and mandatory retirement contributions from gross income.
  • Utah applies a split custody formula when each parent has primary physical custody of at least one child from the relationship.
  • The court may deviate from the guidelines if application would be unjust or inappropriate based on the specific circumstances of the case.

Example Calculation

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined income: $8,000

Step 2: Parent A's share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation for $8,000 combined and 2 children.

Step 4: Multiply by Parent A's share (62.5%).

Adjustments for health insurance, child care, and parenting time may apply.

Utah Child Support FAQ

How is child support calculated in Utah?
Utah uses the Income Shares model under Utah Code § 78B-12. Both parents' adjusted gross incomes are combined, and the basic child support obligation is determined from the state guidelines table. Each parent pays their proportional share based on their percentage of the combined income. The obligation is adjusted for health insurance, child care costs, and parenting time.
What is adjusted gross income for Utah child support?
In Utah, adjusted gross income starts with gross income from all sources, then subtracts one-half of self-employment taxes, alimony previously ordered and paid, and mandatory retirement contributions. This adjusted figure is used for the child support calculation.
Does 50/50 custody affect child support in Utah?
Yes, Utah has specific provisions for joint physical custody. When each parent has the children for at least 111 overnights per year, the child support calculation uses a different formula that accounts for the time each parent spends with the children, potentially reducing the non-custodial parent's obligation.
How long does child support last in Utah?
In Utah, child support generally continues until the child turns 18. If the child is still attending high school at age 18, support continues until the child graduates from high school or turns 18, whichever occurs later, but does not extend past age 19. Support may continue for an adult child with a disability.
Can Utah child support be modified?
Yes, either parent may petition the court for a modification if there has been a substantial change in circumstances. Utah also provides that a modification may be granted if the existing order differs from the current guidelines by 10% or more, or if a cost-of-living adjustment is warranted.
