Nevada Child Support Guidelines: How Support Is Calculated

Nevada does not set child support by a judge's personal sense of fairness — it runs off a formula tied to the paying parent's gross monthly income, applied in graduated income tiers, and that formula is a rebuttable legal presumption the court starts from in every case. The current formula took effect February 1, 2020, when the state replaced its old flat-percentage-with-cap system with an income-tiered model that has no presumptive dollar ceiling.

The Nevada child support formula

Nevada calculates the base child support obligation as a percentage of the paying parent's ("obligor's") gross monthly income, and the percentage drops as income rises through three brackets. According to the guidelines:

• One child: 16% of the first $6,000 of gross monthly income, 8% of income between $6,000 and $10,000, and 4% of income above $10,000.
• Two children: 22% / 11% / 6% across the same three income tiers.
• Three children: 26% / 13% / 6%.
• Four children: 28% / 14% / 7%.
• Each additional child beyond four adds another 2% / 1% / 0.5% to the respective tier.

Because the formula runs on a sliding scale rather than one flat rate applied to all income, a parent's total obligation is really a blend across whichever tiers their income touches — not a single percentage multiplied by their entire paycheck.

Courts apply these guidelines as a rebuttable presumption when they determine or change a support order, meaning the calculated amount is presumed correct unless a party shows the court a reason to deviate from it.

Why this replaced the old system

Before February 2020, Nevada used a flat-percentage model with a presumptive dollar cap on support regardless of how high the paying parent's income went. The regulations adopted that took effect February 1, 2020 eliminated that cap and moved to the tiered-percentage structure described above, so there is no longer an automatic ceiling on the dollar amount of support in higher-income cases.

What counts as "gross income"

The guidelines define gross monthly income broadly. It generally includes wages, self-employment income, rental income, interest and dividends, pensions, Social Security retirement or disability benefits, unemployment benefits, and workers' compensation.

It excludes certain benefits that are not treated as income for this calculation, including Supplemental Security Income (SSI), SNAP (food assistance) benefits, and child support a parent already receives for other children. If you are unsure whether a specific type of income or benefit counts, that is a good question to bring directly to your Nevada court or a local family-law resource, since the underlying regulation lists categories rather than every possible income source.

Shared physical custody changes the math

When parents share physical custody of the children, Nevada does not simply hand one flat number to one parent. Instead, each parent's support obligation is calculated separately as if they were the paying parent, and the two amounts are then offset against each other — the parent with the higher calculated obligation pays the other parent the difference between the two figures.

Low-income adjustments

Nevada's guidelines also include an adjustment for parents with limited ability to pay. When a paying parent's total economic circumstances are constrained, an adjustment tied to federal poverty guidelines can reduce the amount that would otherwise apply under the standard formula. Because this adjustment depends on your specific income and household circumstances, confirm with your Nevada court or a legal-aid resource how it would apply in your case.

When support can be changed — time-sensitive rules

Two rules matter most if your income or circumstances have shifted:

• The 20% income-change trigger: If the gross monthly income of the parent who pays support changes by 20% or more, that is treated as a "changed circumstance" that requires the case to be reviewed for a possible modification. If your income has moved significantly in either direction, this is worth acting on promptly rather than waiting.
• The three-year review right: Separately, either parent or the enforcing authority can request that the court review a support order at least once every three years, even without a 20% income change. If it has been close to three years since your order was last reviewed, you may have a standing right to ask for a fresh look.

Neither of these reviews happens automatically just because time has passed or income changed — a parent (or the enforcing agency) generally has to request it. Don't assume your order updates itself.

How enforcement works — federal backbone, state action

Nevada's child support system does not operate in isolation. Federal law (Title IV-D, 42 U.S.C. §§ 654, 659, 666) requires every state, including Nevada, to run a child-support enforcement agency and to use standardized enforcement tools such as income withholding directly from a paycheck, license suspension, and liens against property. Federal law also waives sovereign immunity so that federal wages and certain federal benefits can be garnished to satisfy a support obligation.

These are federal minimums that all states must build into their enforcement systems — the mechanics of using them in a specific Nevada case (which agency, which forms) are handled through Nevada's own child-support enforcement program and the courts.

If the parents live in different states

If one parent moves out of Nevada, federal law (28 U.S.C. § 1738B) requires other states to enforce a Nevada child-support order and generally bars another state from modifying it except under narrow continuing-jurisdiction rules. This is the federal rule that works alongside Nevada's own interstate support law to determine which state's order controls when parents live apart across state lines.

Child support and bankruptcy

If a paying parent files for bankruptcy, child support is treated as a "domestic support obligation" under federal bankruptcy law. It cannot be discharged (wiped out) in bankruptcy, and it is paid ahead of most other unsecured debts. Property-settlement debts owed to an ex-spouse from a divorce are also generally non-dischargeable in a Chapter 7 bankruptcy. In other words, filing bankruptcy is not a way to escape a Nevada child-support obligation.

What you can do in Nevada

1. Identify your gross monthly income sources and sort them against the categories the guidelines count (wages, self-employment, rental, pensions, Social Security, unemployment, workers' comp) versus excluded items (SSI, SNAP, support received for other children).
2. Figure out your custody arrangement. If you share physical custody, expect both parents' obligations to be calculated and offset, not just one parent's income plugged into the formula.
3. Check whether a low-income adjustment might apply to your situation, and ask the court or a local resource how that adjustment is calculated in practice.
4. Track major income changes. If the paying parent's income moves by roughly 20% or more, that can be grounds to request a review — don't sit on it.
5. Note your three-year review window. If it has been close to three years since the order was set or last reviewed, either parent can request a review.
6. Use Nevada's Self-Help Center resources for the specific forms you'll need — for Clark County or Washoe County cases, the Self-Help Center points to county-specific self-help sites with the correct local forms.
7. If parents live in different states, confirm which state's order currently controls before assuming Nevada's order can simply be changed or ignored.
