How Utah child support law works
Legal starting point. Utah Code chapter 81-6 uses an income-shares system and a statutory base combined child-support table. The correct worksheet depends on whether the case involves sole, joint, or split physical custody. Read Utah Code §§ 81-6-203–204.
How the guideline is calculated
The basic table amount is selected from combined monthly adjusted gross income and allocated by income share. Low-income treatment, custody worksheets, medical support, child care, and deviations are separate statutory steps and should be completed on the applicable Utah form.
What this site’s worksheet covers
Uses Utah Code § 81-6-304 base combined child support obligation table for orders entered on or after January 1, 2023; current version is effective September 1, 2024. The table is based on combined monthly adjusted gross income and number of children, and this base module allocates the combined obligation by each parent’s income share. Low-income obligor table treatment under Utah Code § 81-6-305, sole/split/joint physical custody worksheets, medical support, child care and deviations require the full Utah worksheet. Blank lower-income cells in the statutory base combined table are not filled by this module; those scenarios require the applicable Utah low-income worksheet.
Documents that make the worksheet more useful
Utah income verification and sole, joint, or split custody worksheet. Gather the records that support the income, parenting-time, insurance, child-care, and other adjustment entries that apply to the family. The calculator applies the guideline formula described above and identifies any listed worksheet line it does not compute.

Before you enter your numbers
Does Utah count every hour of overtime as income?
Utah generally limits earned income to the equivalent of one full-time, 40-hour job. The statute allows consideration of extra time when it was a normal and consistent work pattern before the original support order. Current earnings and work history therefore both matter; a recent unusually long workweek is not the whole inquiry.
Prepare this: Bring year-to-date pay records, the most recent tax return, and work-history records showing whether extra hours were customary before the original order.
Read the relevant official instructions: Utah Code §§ 81-6-203–204.
These preparation notes explain one part of the state guideline. A new estimate does not change an existing order; a modification request does.
How Utah cases actually get to a number
Combine adjusted gross income, look up the table, allocate by share, then apply the worksheet’s medical and child-care lines. Utah recodified family law; use the current Title 81 cites, not only older Title 78B memories.
Utah Code section 81-6-304 uses a monthly adjusted-gross-income table and an income-shares allocation, with a worksheet that reaches medical and child-care costs. That is a different path from neighboring states that use another model, so do not import a table, percentage, or overnight credit from somewhere else.
Parenting time in Utah
Joint physical custody has a Utah worksheet treatment based on overnights. A week-on/week-off plan still needs the joint-custody math rather than half of a primary-custody result.
Costs Utah usually treats separately
- Work-related child care
- Medical and dental insurance
- Uninsured medical expenses
- Other statutory add-ons
When Utah courts leave the guideline
Deviation factors are statutory. High income, a child’s special needs, and travel between distant Utah communities appear often.
