Utah calculates child support using the Income Shares Model, which determines payment amounts based on both parents' combined gross monthly income, the number of children, and the custody arrangement. For a family earning $10,000 per month combined with two children, the base child support obligation is approximately $1,848 per month before adjustments for health insurance, childcare, and parenting time credits. The minimum child support order in Utah is $30 per month, and the guidelines tables cover combined incomes up to $100,000 per month under Utah Code § 81-6-304.

How Utah Calculates Child Support Amounts
Utah determines how much child support costs by applying the Income Shares Model, which combines both parents' adjusted gross monthly incomes and divides the total child support obligation proportionally based on each parent's share of that combined income. Under Utah Code § 81-6-204, the court first calculates each parent's adjusted gross income by subtracting alimony previously ordered and child support for other children, then locates the base combined child support obligation in the statutory guidelines table based on the combined income and number of children.
The Income Shares Model operates on the economic principle that children should receive the same proportion of parental income they would have received if both parents lived together. This approach is used by the majority of states nationwide and ensures consistent, predictable outcomes. Utah's implementation includes specific provisions for joint physical custody, medical expenses, and work-related childcare costs that can significantly affect the final payment amount.
To understand how much child support you might pay or receive in Utah, you must gather documentation of both parents' gross monthly income from all sources. Gross income under Utah Code § 81-6-102 includes wages, salaries, commissions, bonuses, royalties, rental income, dividends, severance pay, interest, alimony from a prior marriage, Social Security benefits, and any other prospective earnings. Gross income excludes means-tested welfare benefits such as TANF or food stamps.
Utah Child Support Guidelines Table: Sample Amounts for 2026
The base combined child support obligation table under Utah Code § 81-6-304 establishes the total support amount before dividing it between parents. The following examples illustrate typical monthly obligations based on combined parental income:
| Combined Monthly Income | 1 Child | 2 Children | 3 Children | 4 Children |
|---|---|---|---|---|
| $3,000 | $541 | $807 | $973 | $1,095 |
| $5,000 | $816 | $1,213 | $1,460 | $1,644 |
| $7,500 | $1,060 | $1,573 | $1,890 | $2,128 |
| $10,000 | $1,259 | $1,848 | $2,216 | $2,492 |
| $15,000 | $1,570 | $2,293 | $2,743 | $3,080 |
| $20,000 | $1,818 | $2,649 | $3,163 | $3,548 |
These amounts represent the base obligation only and do not include additions for health insurance premiums, extraordinary medical expenses, or work-related childcare costs. The court divides this base obligation between parents according to their proportional share of the combined income. For example, if one parent earns 60% of the combined income and the other earns 40%, the higher-earning parent pays 60% of the base obligation.
Using the Official Utah Child Support Calculator
The Utah Office of Recovery Services (ORS) maintains the official child support calculator at orscsc.dhs.utah.gov, which applies the current statutory guidelines and produces results consistent with what Utah courts use when setting child support orders. This free online tool requires you to enter both parents' gross monthly incomes, the number of children, the custody arrangement, health insurance costs, and work-related childcare expenses to generate an estimated monthly support amount.
To use the Utah child support calculator accurately, you will need to gather specific financial documents including recent pay stubs showing gross earnings, tax returns from the previous year, documentation of any self-employment income, records of alimony paid or received, and information about health insurance premiums paid for the children. The calculator uses these inputs to apply the Income Shares formula and generate an estimate that closely approximates what a court would order.
The calculator produces estimates only and does not create legally binding child support orders. ORS or the court decides the final amount after reviewing all evidence and considering any applicable deviations from the guidelines. However, the calculator provides an excellent starting point for understanding your potential obligation or entitlement before filing for divorce or child support establishment.
Joint Physical Custody Adjustments in Utah
Utah applies a joint physical custody adjustment when the obligor parent has 111 or more overnights per year with the child, which represents more than 30% of annual parenting time. Under Utah Code § 81-6-206, parents who share physical custody use a separate Joint Physical Custody Worksheet (Form 1020FA) that applies a graduated reduction formula decreasing the obligor's payment based on the number of overnights.
The 111-overnight threshold is distinctive to Utah and creates significant financial implications for parents negotiating custody arrangements. When both parents have substantial parenting time, the theory is that each parent already incurs direct costs for housing, food, and activities during their parenting time, so the child support transfer payment should be reduced accordingly. A parent with exactly 111 overnights receives a different adjustment than a parent with 182 overnights (50/50 custody).
If you have 110 or fewer overnights per year, you use the standard sole custody worksheet and pay the full proportional share of the base obligation. Crossing the 111-overnight threshold triggers the joint custody worksheet, which typically results in a lower monthly payment. This creates strong incentives for obligor parents to negotiate for at least 111 overnights, while custodial parents may prefer arrangements that keep the obligor below this threshold.
Additional Expenses Beyond Base Child Support
Utah courts add health insurance premiums and work-related childcare costs to the base child support obligation and divide these amounts proportionally between parents based on their income shares. Under Utah Code § 81-6-208, the cost of health insurance premiums attributable to the children must be added to the base obligation, with each parent responsible for their proportional share.
Work-related childcare costs necessary for a parent's employment or education leading to employment are treated similarly. Beginning July 1, 2026, Utah law requires all child support orders to include a provision for the obligor parent to pay a reasonable ongoing expense for childcare costs. This represents a significant change that will affect how childcare expenses are handled in new and modified orders.
Extraordinary medical expenses, defined as uninsured medical costs exceeding $250 per child per year, are also divided between parents. These expenses include orthodontics, mental health treatment, physical therapy, and other significant medical needs. Parents must provide documentation of these expenses and typically divide them according to their income shares, though courts have discretion to order alternative arrangements.
How to File for Child Support in Utah
To establish a child support order in Utah, you have two primary options: filing through the district court as part of a divorce or parentage action, or applying for services through the Utah Office of Recovery Services (ORS). The filing fee for a divorce petition that includes child support is $325 under Utah Code § 78A-2-301, payable when you submit your Petition for Divorce to the district court clerk.
If you are not married to the other parent, you can establish paternity and child support through ORS at no cost to you. ORS provides services including locating the other parent, establishing paternity through genetic testing, calculating child support using the guidelines, and enforcing orders through wage withholding. Parents receiving TANF benefits are automatically referred to ORS for child support services.
Before filing for divorce with child support, you must meet Utah's residency requirement of 90 days in both the state and the specific county where you plan to file under Utah Code § 81-4-402. Divorces involving minor children have a mandatory 90-day waiting period after filing before the court can finalize the decree. This waiting period allows time for completing mandatory parenting education courses.
Modifying Child Support Orders in Utah
Utah permits modification of child support orders when there has been a substantial change in circumstances that is not temporary, meaning the change is expected to last at least 12 months. Under Utah Code § 81-6-212, a parent can petition for modification at any time if they can demonstrate qualifying changes in income, custody, medical needs, or legal responsibilities.
The filing fee for a petition to modify child support is $100. If the child support order has not been modified within the last three years, you can request modification if recalculating support under current guidelines would result in a difference of at least 10% from the existing order amount. If the order was modified within the last three years, the threshold increases to 15%, and you must also show an additional change in circumstances beyond income changes.
For simpler cases, Utah allows a Motion to Adjust rather than a full Petition to Modify when the order is at least three years old and recalculating would change the amount by 10% or more. This streamlined process is faster and less expensive than a full modification petition. However, a change in the child support guidelines tables alone is not considered a substantial change in circumstances justifying modification.
Child Support Enforcement in Utah
The Utah Office of Recovery Services (ORS) enforces child support orders through multiple collection tools including wage garnishment, tax refund interception, license suspension, credit bureau reporting, asset seizure, and property liens. Under Utah Code § 62A-11-316, up to 50% of an obligor's disposable earnings can be withheld from each paycheck for child support arrears.
Wage garnishment is the most common enforcement method, with employers required to withhold child support from paychecks and remit payments directly to ORS. All child support orders in Utah must include an income withholding provision. For self-employed parents or those who change jobs frequently, ORS uses other collection methods including intercepting federal and state tax refunds and other government payments.
Utah can suspend driver's licenses, professional licenses, and recreational licenses (hunting, fishing) for non-payment of child support. This enforcement tool affects doctors, nurses, teachers, contractors, real estate agents, and other licensed professionals who cannot work without valid credentials. Courts can also hold non-paying parents in contempt, which may result in fines or imprisonment in extreme cases of willful non-payment.
How Long Child Support Lasts in Utah
Utah child support obligations continue until the child reaches age 18 or graduates from high school during the normal and expected year of graduation, whichever occurs later. Under Utah Code § 81-6-102, a child is defined as a son or daughter who is under 18, not emancipated, not self-supporting, not married, and not a member of the armed forces.
Child support terminates automatically when a child becomes emancipated, marries, joins the military, or dies. The obligation also ends if the child becomes self-supporting before age 18 or if parental rights are terminated. Parents should file paperwork to formally terminate support when these events occur to avoid unnecessary ongoing obligations or confusion about arrears.
For high school students who turn 18 before graduation, child support continues through the expected graduation year. Utah does not require parents to pay child support for adult children attending college, though parents can voluntarily agree to contribute to post-secondary education costs in their divorce settlement. Any such agreement becomes enforceable as part of the divorce decree but is not mandated by statute.
Tax Implications of Utah Child Support
Child support payments are tax-neutral under federal and Utah state tax law, meaning the paying parent cannot deduct child support payments and the receiving parent does not report them as taxable income. This treatment differs from alimony, which may be tax-deductible for the payer and taxable to the recipient for divorces finalized before January 1, 2019.
The child tax credit and dependency exemption typically go to the custodial parent, defined as the parent with whom the child lives for more than half the year. However, Utah courts can allocate these tax benefits between parents as part of the divorce decree. Non-custodial parents can claim the dependency exemption only if the custodial parent signs IRS Form 8332 releasing the exemption.
Parents should carefully consider the tax implications when negotiating child support and custody arrangements. The value of the child tax credit (up to $2,000 per qualifying child) and other dependent-related tax benefits can significantly affect each parent's after-tax income. Including clear provisions about tax benefits in the divorce decree prevents future disputes.
Imputed Income for Unemployed or Underemployed Parents
Utah courts can impute income to parents who are voluntarily unemployed or underemployed, meaning the court calculates child support based on what the parent could earn rather than actual current earnings. Under Utah Code § 81-6-105, imputed income is based on the parent's employment potential and probable earnings considering work history, occupational qualifications, educational attainment, and prevailing job opportunities in the community.
A parent cannot reduce their child support obligation by quitting a job, reducing hours, or taking a lower-paying position without good cause. Courts scrutinize employment changes that occur around the time of divorce or custody proceedings. If a parent previously earned $80,000 per year but now claims to earn $30,000 after voluntarily leaving their job, the court may calculate support based on the $80,000 earning capacity.
Exceptions apply when a parent has legitimate reasons for reduced earnings, such as caring for a young child, pursuing education that will increase future earning capacity, physical or mental disability, or job loss due to circumstances beyond their control. Parents must document their job search efforts and present evidence of why they cannot earn at their historical level to avoid imputation.
Frequently Asked Questions About Utah Child Support
How much is child support in Utah for one child?
Utah child support for one child varies based on both parents' combined income and the custody arrangement. For parents with combined monthly income of $5,000, the base obligation is $816 per month for one child under Utah Code § 81-6-304. This amount is divided proportionally between parents based on each parent's share of the combined income, so the actual payment depends on the income split.
What is the minimum child support payment in Utah?
The minimum child support order in Utah is $30 per month regardless of the obligor's income level. This minimum applies even when a parent has very low income or is unemployed. Courts rarely order below this threshold unless extraordinary circumstances exist. The minimum ensures that children receive at least nominal support from both parents.
Does Utah use gross or net income for child support?
Utah uses gross income, not net income, when calculating child support under the Income Shares Model. Gross income includes all earnings before taxes and deductions from wages, self-employment, investments, retirement benefits, and other sources. The only adjustments allowed are subtracting alimony previously ordered and child support for other children.
How does joint custody affect child support in Utah?
Joint physical custody significantly reduces child support payments in Utah when the obligor parent has 111 or more overnights per year. The Joint Physical Custody Worksheet applies a graduated adjustment that decreases support based on shared parenting time. A parent with 182 overnights (50/50 custody) pays substantially less than under sole custody arrangements.
Can child support be modified if I lose my job?
Yes, involuntary job loss can justify child support modification in Utah if the change is substantial and expected to last at least 12 months. You must file a Petition to Modify and demonstrate that recalculating support under current guidelines would change the amount by at least 10-15% depending on when the order was last modified. Document your job search efforts to show the change is involuntary.
How long does it take to get a child support order in Utah?
A child support order through Utah courts typically takes 30-90 days depending on whether the case is contested. Divorces with children require a mandatory 90-day waiting period. Establishing support through ORS may take 60-120 days including time to locate the other parent and complete necessary paperwork. Contested cases can take 6-12 months or longer.
Can I get child support if we were never married?
Yes, unmarried parents have the same right to child support in Utah as married parents. You must first establish legal paternity through voluntary acknowledgment or genetic testing. The Utah Office of Recovery Services provides free paternity and child support establishment services. Once paternity is established, support is calculated using the same guidelines that apply to divorced parents.
What happens if child support is not paid in Utah?
Utah enforces unpaid child support through wage garnishment (up to 50% of disposable income), tax refund interception, license suspension (driver's, professional, recreational), credit bureau reporting, bank account levies, and property liens. The Office of Recovery Services can pursue enforcement actions. Courts can also hold non-paying parents in contempt, potentially resulting in jail time.
Does child support cover college expenses in Utah?
No, Utah does not require parents to pay child support for adult children attending college. Child support terminates at age 18 or high school graduation, whichever is later. Parents can voluntarily agree to contribute to college costs in their divorce settlement, and such agreements become enforceable, but courts cannot order college support absent an agreement.
How do I calculate child support if one parent lives out of state?
When one parent lives outside Utah, child support is still calculated using Utah guidelines if Utah has jurisdiction over the case. The out-of-state parent's income is included in the combined income calculation just like a Utah resident. ORS can coordinate with other states' child support agencies to locate parents, establish orders, and enforce payment across state lines.
