Self-Employment Income and Child Support in Utah
Short answer: For Utah child support, a self-employed parent’s income is gross receipts minus the expenses necessary to run the business at a reasonable level. Utah Code § 81-6-203(4). The court reviews the business’s income and expenses to find the income actually available for support, and that figure may differ from the business income on the tax return.
If you’re a business owner going through a divorce or custody case in Utah, child support and self-employment income can get complicated fast. Unlike W-2 wages, self-employment income can be influenced by deductions, write-offs, timing, and how money moves through a business.
Utah courts handle this with a clear rule: for child support, the goal is to determine the income actually available to support a child, not just what appears on a tax return. Under Utah Code § 81-6-203, self-employment income is generally calculated as gross receipts minus necessary business expenses, and those expenses must be truly necessary to keep the business operating at a reasonable level. The statute also makes clear that child support income may differ from taxable income.
If you’re trying to estimate child support, or you’re concerned the other parent is underreporting business income, this guide explains what Utah courts look at and how to prepare.
Key takeaway: Utah uses “gross receipts minus necessary expenses”
For a self-employed parent, Utah law directs the court to start with gross receipts (the money coming into the business) and subtract necessary expenses.
But here’s the part that matters in most disputes: the court may only deduct expenses necessary to allow the business to operate at a reasonable level.
And Utah specifically warns against treating the tax return as the final answer:
“Gross income… may differ from the amount of business income determined for tax purposes.”
Why taxable income isn’t the same as child support income
Tax rules are designed to determine taxable profit. Child support rules are designed to determine ability to support a child. As a result, some deductions that reduce taxes may not reduce income for child support purposes if they aren’t truly necessary or they provide personal benefit.
What Utah courts review for self-employed child support cases
Utah courts are instructed to review self-employment income and expenses “to determine an appropriate level of gross income available to the parent to satisfy a child support award.”
That means the court may look past the headline numbers and examine the reality of the business, including:
Owner draws, distributions, and how profits are taken
Retained earnings and access to business funds (in some situations)
Personal expenses paid through the business
Whether claimed expenses are necessary or discretionary
Whether reported income matches lifestyle and spending
Utah case example: a short revenue dip does not lower income
In Lunt v. Lunt, 2024 UT App 148, the Court of Appeals held that the trial court acted within its discretion in declining to account for a three-month drop in the husband’s business revenue during the COVID-19 pandemic when calculating his gross income. A short-term dip did not outweigh the broader earning history.
If one parent controls a business, Utah courts can focus on the full financial picture, not just what the parent chooses to call “income.”
Common self-employment expense issues in child support
Because Utah only allows deduction of expenses needed to operate at a reasonable level, disputes often involve “gray area” items like:
Vehicle expenses (especially multiple vehicles)
Meals, travel, and “business development”
Home office allocations
Depreciation and large write-offs
Payments to family members
“One-time” expenses that reduce profits on paper
Many of these may be legitimate for taxes, but child support looks at whether they are actually necessary and whether they reduce the income available to support a child.

FAQs: Self-employment income and Utah child support
Can a Utah court ignore my tax return?
The court can consider it, but Utah law explicitly allows child support gross income to differ from tax-based business income.
What if my business income changes month to month?
Volatile income often leads to deeper documentation review (monthly profit and loss statements, bank statements, year-over-year comparisons). A short-term dip may not be enough by itself to prove a long-term reduction, depending on the evidence. See generally Lunt, where the court evaluated the evidence rather than relying on a narrow snapshot.
What if the other parent is hiding income in a business?
Courts can analyze receipts and expenses, and attorneys often request business bank statements, credit card statements, general ledgers, payroll reports, and documents showing distributions and retained earnings. The goal is to determine the income actually available for support.
