Child support is one of the most practically significant issues in any Nevada family law case involving children. It determines the monthly financial obligation a parent must meet, and it follows a child through their upbringing until they reach adulthood. Despite its importance, the calculation process is poorly understood by most parents going through a separation or divorce for the first time.
Nevada uses a statutory formula to calculate child support, codified in NRS 125B.070. The formula is designed to produce consistent, predictable results tied to the paying parent’s income, but it has important variables and exceptions that can significantly affect the outcome. Here is how it works.
The Basic Formula: Percentage of the Obligor’s Gross Monthly Income
Nevada’s child support formula is based on the gross monthly income of the parent who is ordered to pay support, referred to as the obligor. The applicable percentage of that income depends on the number of children who are the subject of the order:
- 1 child: 18% of gross monthly income
- 2 children: 25% of gross monthly income
- 3 children: 29% of gross monthly income
- 4 children: 31% of gross monthly income
- 5 or more children: no less than 33% of gross monthly income
Gross monthly income means income before taxes and other deductions. It includes wages, salary, commissions, bonuses, self-employment income, rental income, interest, dividends, and virtually all other regular sources of income. It does not include public assistance payments or payments received from this child support order.
The formula produces a presumptive amount — what the law treats as the correct support amount in the absence of specific factors that warrant an adjustment. Courts may deviate from the presumptive amount when the circumstances justify it, but they must state their reasons for doing so on the record.
Income Cap: The Statutory Maximum
Nevada’s child support formula applies to the obligor’s gross monthly income up to a statutory cap. Under NRS 125B.070(2), the cap is adjusted periodically. When the paying parent’s income exceeds the cap, the court retains discretion to award additional support, but the formula does not automatically continue to apply at the same percentage above the ceiling. Parents with high incomes should be aware that child support above the cap is subject to judicial discretion rather than formula calculation.
How Custody Arrangements Affect Support
The formula percentages above apply in a primary physical custody arrangement where one parent has the child for the majority of time and the other parent has standard parenting time. When parents share joint physical custody with a more equal time division, a different analysis applies.
In a joint physical custody arrangement, Nevada courts calculate each parent’s presumptive support obligation based on their respective incomes and then offset the two amounts against each other. The parent with the higher income pays the difference to the parent with the lower income. This offset calculation reflects the fact that both parents are sharing the direct costs of raising the child during their respective parenting time.
The exact calculation in joint custody scenarios requires knowing both parents’ gross monthly incomes, the percentage of time each parent has the child, and any applicable adjustments for additional expenses. The result is not always intuitive, and errors in these calculations can compound over years of monthly payments.
Adjustments and Deviations from the Presumptive Amount
Nevada law recognizes that the formula-based presumptive amount may not be appropriate in every case. Under NRS 125B.080, courts may deviate from the presumptive amount based on specific factors, including:
- The legal responsibility of the obligor for the support of other children from prior or subsequent relationships
- The value of services contributed by either parent to the care of the child
- Any public assistance payments being received for the child
- Reasonable expenses for the child’s education, including private school or special education needs
- The cost of medical, dental, or other health insurance coverage for the child
- The relative income of both parents and their respective financial obligations
- Any income or assets of the child
- The physical and emotional condition of the child and any special needs
- Any other relevant factors the court determines should be considered
Health insurance costs for the child are particularly significant. Nevada courts routinely add the cost of the child’s health insurance premium to the basic child support obligation, prorated between the parents in proportion to their respective incomes.
What Counts as Income for Child Support Purposes?
Nevada takes a broad view of income for child support calculations. In addition to regular employment income, courts will consider self-employment earnings (adjusted for legitimate business expenses), overtime and bonus income that occurs with regularity, rental income, investment returns, and income from trusts or inheritances. Courts may also impute income to a parent who is voluntarily underemployed or unemployed without good cause — attributing to them the income they could reasonably earn given their education, work history, and job market conditions.
Self-employed parents or those with irregular income present particular challenges because income fluctuates and business expenses can be difficult to evaluate. A forensic accounting analysis may be necessary when self-employment income is a significant part of the support calculation.
Child Support and College or Post-Secondary Education
Nevada’s basic child support obligation typically ends when the child turns 18 or graduates from high school, whichever occurs later, but no later than the child’s 19th birthday under NRS 125B.110. Unlike some other states, Nevada does not have a statutory obligation for parents to contribute to college tuition or post-secondary education expenses beyond this age, though parents are free to agree to such contributions voluntarily and courts can incorporate such agreements into the order.
Modifying a Nevada Child Support Order
Child support orders are not permanent. Either parent can petition the court to modify the order when there has been a change in circumstances. Under NRS 125B.145, Nevada courts will review a support order if three years have passed since it was entered or last modified, or if there has been a substantial change in the financial circumstances of either parent.
Common reasons for modification include a significant change in either parent’s income, a change in the custody arrangement that affects time-sharing, the child developing new medical or educational needs, or one parent becoming unemployed or underemployed. The modification process requires a formal court petition and cannot be accomplished by informal agreement between the parents — informal modifications are not enforceable and can create arrears for the paying parent.
Enforcement of Child Support Orders in Nevada
When a parent fails to pay ordered child support, Nevada has robust enforcement mechanisms available through both the courts and the Nevada Division of Welfare and Supportive Services (DWSS). Enforcement tools include wage garnishment, interception of state and federal tax refunds, suspension of driver’s licenses and professional licenses, reporting to credit bureaus, and contempt of court proceedings that can result in fines or incarceration in serious cases.
Unpaid child support — known as arrears — accumulates with interest under Nevada law and does not go away through bankruptcy. Parents who fall behind should seek legal advice and, where appropriate, pursue a formal modification rather than allowing arrears to compound.
