How Nevada child support law works
Legal starting point. Nevada’s support law uses the statutory and regulatory guideline framework in chapter 425. The calculation differs by custody arrangement, so a primary-custody percentage calculation should not be treated as a substitute for a joint- or split-custody worksheet. Read Nevada NAC 425.025 and 425.140.
How the guideline is calculated
For primary custody, the guideline begins with the obligor’s gross monthly income and the applicable tiered percentage. Joint custody, split custody, low-income treatment, medical support, child care, and deviations require the specific Nevada calculation that fits the family’s facts.
What this site’s worksheet covers
Primary custody base obligation under NAC 425.140 only. Joint physical custody, split custody, low-income schedule, medical support, childcare and court deviations require separate Nevada worksheet handling. Each child beyond four adds 2%, 1% and 0.5% to the three respective income tiers.
Documents that make the worksheet more useful
Nevada financial disclosure and primary, joint, or split custody computation. Gather the records that support the income, parenting-time, insurance, child-care, and other adjustment entries that apply to the family. Both parties are disclosed; joint/split custody requires the full rule calculation beyond the ordinary base module. All additional-child tier increments are implemented.
For a filing or agreement, complete the official court forms linked on this page. They use the same guideline structure explained here, and the court applies it to the facts of the case.
Before you enter your numbers
Does Nevada apply one percentage to all income?
Nevada's ordinary guideline uses income brackets with different percentage rates, rather than a single rate applied indiscriminately to the whole amount. Joint custody requires calculating the applicable obligations for both parents and considering the offset. The low-income schedule is another distinct path.
Prepare this: Record each parent's gross monthly income, the custody arrangement, and the number of children. Use the current low-income schedule when applicable rather than extending a higher-income tier downward.
Read the relevant official instructions: Nevada NAC 425.025 and 425.140.
These preparation notes explain one part of the state guideline. A new estimate does not change an existing order; a modification request does.
How Nevada cases actually get to a number
For primary custody, apply the statutory/NAC tiered percentage to gross monthly income. Joint custody is not ‘half of primary.’ Low-income treatment is its own NAC path.
Nevada chapter 425 and NAC 425 use a tiered percentage of the obligor’s gross monthly income for primary custody, and entirely different calculations for joint or split custody. That is a different path from neighboring states that use another model, so do not import a table, percentage, or overnight credit from somewhere else.
Parenting time in Nevada
Classify the custody type first. Joint physical custody in Nevada has a specific formula. Using the primary-custody percentage on a joint-custody family will not match NAC 425.
Costs Nevada usually treats separately
- Medical support
- Child-care costs
- Insurance premiums
- Other NAC 425 adjustments
When Nevada courts leave the guideline
Deviation factors are in statute. High income, a child’s special needs, and travel between homes (common in Nevada’s geography) belong in findings.
Official Nevada forms to keep beside this guide
Nevada financial disclosure and primary, joint, or split custody computation. Both parties are disclosed; joint/split custody requires the full rule calculation beyond the ordinary base module. All additional-child tier increments are implemented. The primary authority is the published Nevada source. Fill the official form from source documents. Use this page only to check that you chose the right Nevada path—primary versus shared, table versus percentage, add-ons versus basic support.
Where this is typically filed
District Court family divisions hear cases; DCSS handles IV-D. Use current NAC 425 tables, which have been amended.
Questions specific to Nevada
Is Nevada income-shares?
Primary custody is a tiered percentage of the obligor’s gross monthly income. Joint custody is a different calculation.
Gross or net?
The primary-custody percentages start from gross monthly income as defined in the NAC.
Does 50/50 custody use half the percentage?
No. Joint custody has its own Nevada formula.

Example: apply each income tier separately
Primary physical custody, six children and $12,000 in the obligor’s monthly gross income; no low-income determination or additional adjustment.
- For six children, the first $6,000 uses 32%: $1,920.
- The next $4,000 uses 16%: $640.
- The remaining $2,000 uses 8%: $160.
- The base total is $1,920 + $640 + $160 = $2,720 per month.
Do not apply the first-tier percentage to all income. Each child after four increases every tier’s rate. Joint physical custody requires determining and offsetting both parties’ obligations instead of using this primary-custody result.
