Child support · Utah
Utah child support calculator
Utah uses the income-shares model: both parents’ adjusted gross monthly income is combined and applied to the § 81-6-304 base obligation table, child care and health insurance are added, and the total is split in proportion to income. This calculator applies Utah Code § 81-6-304 and shows every step.
Calculate guideline support
Enter both parents’ adjusted gross monthly income. Add work-related child care and the children’s health-insurance premium if any.

The base obligation table
The heart of the calculation is the base combined child support obligation table in § 81-6-304 — for each number of children (one to six) and each bracket of combined adjusted gross monthly income, the table gives the total support the two parents together owe. It runs from $1,951 up to $100,000 combined per month; between listed rows the amount is interpolated.
Utah Code § 81-6-304 (base combined child support obligation table, orders on or after Jan 1 2023; effective 9/1/2024).
Child care, health insurance and low income
To the base obligation Utah adds work-related child care and the children’s health-insurance premium, which are shared in proportion to income. The combined figure is the total obligation, split by income share. When combined income is below $1,951/month the base table does not apply and Utah uses the low-income table (§ 81-6-305), keyed to the obligor’s income alone.
Utah Code § 81-6-304 (additions), § 81-6-305 (low-income table).
Shared custody and deviations
When each parent has the children at least 111 overnights a year, Utah applies its shared-parent-time formula, which adjusts and offsets each parent’s share by the time the children spend with the other; split custody (each parent keeping at least one child) uses a separate worksheet. Because those need the exact overnight split, this calculator computes the standard (sole-custody) obligation.
Utah Code § 81-6-105 (parent-time adjustments); § 81-6-301 (deviations).

What this calculator does not do
It combines both parents’ income, looks up the § 81-6-304 table, adds child care and health insurance, and splits the total by income share. It does not compute adjusted gross income from your pay stubs, run the shared- or split-custody offset, apply the low-income table in detail, add extraordinary expenses, or apply a deviation the court may order. For a figure you can file, use the Utah ORS online calculator or consult an attorney.
Common questions
How is child support calculated in Utah?
Combine both parents’ adjusted gross monthly income, look up the § 81-6-304 base obligation table for the number of children, add work-related child care and health insurance, and split the total in proportion to income. The noncustodial parent pays their share.
What is the Utah child support table?
Utah Code § 81-6-304 — the base combined child support obligation table for orders on or after January 1, 2023, indexed by combined adjusted gross monthly income (from $1,951 to $100,000) and one to six children.
What if income is below $1,951 or above $100,000?
Below $1,951 combined monthly income the base table does not apply and Utah uses the low-income table (§ 81-6-305), based on the obligor’s income alone. Above $100,000 combined the court sets support at its discretion, at least the highest table amount.
What about shared custody?
When each parent has the children at least 111 overnights a year, Utah applies its shared-parent-time formula and offsets each parent’s share by the other parent’s time; split custody uses a separate worksheet.
Is child support taxable in Utah?
No — federally it’s not taxable to the recipient or deductible by the payer, the same in Utah as everywhere.
