Utah Child Support Calculator 2026

It was repealed. H.B. 366 of 2024 recodified the whole Utah family code effective September 1, 2024, and the Child Support Act moved to Title 81, Chapter 6. The tables once numbered 78B-12-301 and -302 are now 81-6-304 and 81-6-305, and joint custody moved from 78B-12-208 to 81-6-206. The math survived the move; the citations did not. A calculator or article quoting 78B-12 is working from a dead statute number, which is worth noticing before trusting its other details.

The threshold is 110 overnights, which is just over 30 percent of the year, and it defines joint physical custody. The money starts moving one night later: each overnight over 110 and under 131 earns a credit of 0.0027 times the base combined obligation, and each overnight over 130 earns 0.0084. At 110 nights exactly, joint custody applies but the credit is zero.

Yes. The credits subtract from the lesser-overnight parent share of the base obligation, and the statute says a negative result flips the obligation to the other parent at the same dollar amount. That happens most often when the lesser-overnight parent earns much less and has close to half the nights.

By deeming, not counting. A year has 365 nights, so one parent always hosts 183. For equal schedules under section 81-9-305, the statute assigns the 183 overnights to the LOWER-income parent no matter who actually has the extra night, which makes the higher earner the lesser-overnight parent and usually the payer.

Gross, with targeted subtractions. Section 81-6-203 counts prospective income from earned and unearned sources before taxes, though earned income is capped at one full-time 40-hour job. Child support ordered for other cases and alimony previously ordered and paid come off to reach adjusted gross income. TANF, SSI, SSDI, SNAP, and the child own income stay out entirely.

$30 a month in a sole custody case. Before the minimum applies, low-income payers get a second protection: when the payer income falls within the 81-6-305 low income table, the award is the lesser of the normal income-shares figure and the low income row, so the table can pull an award well below what the shares math alone would produce.

Equally, which surprises people used to other states. The children portion of the premium and reasonable work-related child care are shared half-and-half between the parents regardless of income, under sections 81-6-208 and 81-6-209. Starting July 1, 2026, new orders must also include an ongoing child care expense provision using ORS cost tables, which the agency had not published as of this page date.

Yes. The Office of Recovery Services publishes one at orscsc.dhs.utah.gov, and it is the number to bring to court. This page exists to show the work: the bracket lookup, the credit bands, and the low income comparison, each with its statute cite, so you can see why the official figure is what it is.
