  • Gross monthly income means income from any source before taxes; the court may also impute income to an unemployed or underemployed parent.
  • Obligors with low income use the schedule in NAC 425.145, and courts may adjust for the child's special needs, health insurance and other factors in NAC 425.150.
Standing assumptions
  • Tiered percentages from NAC 425.140 and the joint physical custody offset from NAC 425.115.
  • Joint physical custody is treated as each parent having at least 40% of the time, following Nevada case law.

How Nevada calculates child support

Nevada moved its guidelines from the statutes into chapter 425 of the Nevada Administrative Code effective February 1, 2020. NAC 425.140 sets support as a percentage of the obligor's gross monthly income in three tiers. For one child the obligor pays 16% of the first $6,000, 8% of income between $6,000 and $10,000, and 4% of income above $10,000. Two children use 22%, 11% and 6%; three children 26%, 13% and 6%; four children 28%, 14% and 7%. Each additional child adds 2%, 1% and 0.5% to the three tiers.

The old presumptive maximum, which had capped support at roughly $1,165 per child per month, no longer exists, so high earners pay the tiered percentages on all of their income.

Gross monthly income

NAC 425.025 defines gross income as all income from any source before deductions, including salary, wages, overtime, bonuses, commissions, self-employment income after ordinary business expenses, interest, dividends, rental income, pensions, Social Security and disability benefits, and unemployment. The court can impute income to a parent who is underemployed or unemployed without good cause, based on the parent's work history, education and the local job market.

Joint physical custody

Under NAC 425.115 and the Nevada Supreme Court's decision in Rivero v. Rivero, joint physical custody means each parent has the children at least 40% of the time. In that case the court calculates each parent's obligation under the tiered percentages and orders the parent with the higher obligation to pay the difference. When one parent has primary physical custody, the other parent pays the full guideline amount on their own income.

Low-income obligors and adjustments

NAC 425.145 contains a separate schedule for obligors whose gross monthly income is at or below a threshold the Division of Welfare and Supportive Services updates each year; support for those parents is a smaller fixed amount rather than the percentage. NAC 425.150 lets the court adjust the guideline amount for the child's special educational needs, the cost of health insurance and childcare, the cost of transportation for visitation, the relative income of both households, and the obligor's legal responsibility for other children.

Duration and modification

Support continues until the child turns 18, or 19 if still enrolled in high school. Under NRS 125B.145 an order can be reviewed every three years on request, and modified at any time when the obligor's gross monthly income changes by 20% or more or another substantial change occurs.

Worked example

  1. The paying parent earns $8,000 per month gross and there are two children.
  2. The first $6,000 is charged at 22%, or $1,320.
  3. The next $2,000 is charged at 11%, or $220.
  4. Total guideline support is $1,540 per month.

Guideline child support of $1,540 per month for two children on $8,000 of gross income.

Nevada child support questions

Is there a maximum child support amount in Nevada?

Not since 2020. The tiered percentages apply to all income, although the rates on income above $6,000 and $10,000 are lower.

How does 50/50 custody work in Nevada?

It is joint physical custody. Each parent's obligation is calculated on their own income and the higher earner pays the difference to the other parent.

Does Nevada use gross or net income?

Gross monthly income before taxes, which is why the percentages are lower than in net-income states.

When can I modify a Nevada child support order?

Every three years on request, or earlier if gross income changes by at least 20% or there is another substantial change in circumstances.

Where is the official Nevada calculator?

The Nevada Division of Welfare and Supportive Services publishes a child support guideline calculator that applies NAC chapter 425.
