Nevada Child Support

How Is Child Support Calculated in Nevada? The Formula, Real Numbers, and How Much You Will Actually Pay

Nevada child support is not a mystery and it is not a negotiation from zero. It is a formula: percentages of gross monthly income, tiered by income level, adjusted for the custody arrangement. There is no single "standard amount." Anyone quoting one without asking about income and custody is guessing. Once you understand the machine, you can predict your number and plan around it. You can also spot when the other side's demand has left the guidelines behind. Here is how the calculation works, and what it produces at real incomes.

The Formula: Tiered Percentages by Number of Children

Under Nevada's guidelines, the base obligation is a percentage of the paying parent's gross monthly income (GMI), applied in tiers. The percentages step down as income rises, so higher earners pay a smaller percentage of the dollars above each threshold. The schedule works like this:

Children	First $6,000 of GMI	$6,000 to $10,000	Above $10,000
1 child	16%	8%	4%
2 children	22%	11%	6%
3 children	26%	13%	6%
4 children	28%	14%	7%

Each additional child adds a small percentage on top: roughly 2% on the first tier and 1% on the upper tiers per child beyond three. One date matters when you read older articles: the tiered formula took effect February 1, 2020, and it eliminated Nevada's old maximum caps. There is no ceiling now. The percentages taper at higher incomes, but the obligation keeps growing.

How Much Is Child Support in Nevada? Real Numbers at Real Incomes

Applying the one-child tiers across common incomes, the base obligation looks like this:

Gross Monthly Income	1 Child	2 Children
$3,000	$480	$660
$4,500	$720	$990
$6,000	$960	$1,320
$8,000	$1,120	$1,540
$10,000	$1,280	$1,760
$15,000	$1,480	$2,060

A worked example behind the table: one child, $8,000 gross per month. The first $6,000 generates $960 (16%). The next $2,000 generates $160 (8%). Base obligation: $1,120 per month. Three children run 26%/13%/6%, so the $6,000 earner's base is about $1,560. These are base figures, before adjustments and before the custody schedule enters the math.

What Counts as Gross Monthly Income

More than your paycheck. Nevada counts income from essentially all sources: salary and wages, bonuses and commissions, self-employment income, rental income, pensions, and more. For self-employed parents, the number is business receipts minus legitimate business expenses, and "legitimate" gets tested: personal spending run through a business does not reduce child support. Courts can also impute income to a parent who is voluntarily unemployed or underemployed, calculating support on what they could earn rather than what they choose to earn.

What does NOT count: child support received for children from another case, public assistance benefits, and Supplemental Security Income. Fluctuating incomes get averaged. For seasonal work, commissions, and gig income, courts commonly average earnings over a longer period rather than snapshotting one good or bad month.

How Custody Changes the Calculation

Nevada draws the custody line by overnights across the year. Primary physical custody means one parent has the child more than 60% of the time. Joint physical custody means each parent has at least 40% of the overnights, roughly 146 nights a year. The label controls which math applies.

Primary physical custody: the formula runs once. The non-custodial parent pays the custodial parent the guideline amount, and the custodial parent's income is not part of the base calculation.

Joint physical custody: the formula runs twice. Each parent's obligation is calculated from their own income, the two numbers are offset, and the higher earner pays the other parent the difference. This is why the custody schedule and support are so connected, and why parenting-time disputes so often carry a financial undercurrent. Equal time does not mean zero support unless incomes are equal too.

The Joint Custody Offset, Worked Out

Because this is where most confusion lives, here is the offset with real numbers. Two parents share joint physical custody of one child. Parent A grosses $8,000 per month; Parent B grosses $4,500.

• Parent A's guideline obligation: 16% of $6,000 ($960) plus 8% of $2,000 ($160) = $1,120
• Parent B's guideline obligation: 16% of $4,500 = $720
• The offset: $1,120 minus $720 = Parent A pays Parent B $400 per month

Notice what the offset does and does not do. It does not punish the higher earner; it balances the child's standard of living across two homes. And it means "we have 50/50, so nobody pays" is only true when incomes are close. Equal time equalizes the formula, not the paychecks.

How Income Gets Proven, and What Happens When It Is Hidden

The formula is only as honest as the income figures feeding it, so Nevada builds in verification. Both parents file a sworn Financial Disclosure Form, backed by pay stubs, tax returns, and account statements, under penalty of perjury. W-2 income is simple. The disputes cluster around everything else.

Self-employment is the classic battleground. The guideline number runs on business receipts minus legitimate business expenses, and "legitimate" gets litigated: the truck that is really a personal vehicle, the "office" that is a vacation, the salary a business owner pays themselves that is a fraction of what the business earns. Courts can look through the entity to the real economics, and experienced family lawyers know where to look.

Imputed income is the answer to strategic underemployment. A parent who quits a $90,000 job for "flexibility" the month before the support hearing, or who stays voluntarily unemployed, can have support calculated on their earning capacity: what their skills, history, and the local job market say they could earn. The court asks why the income dropped, whether the change was in good faith, and what the parent is doing about it. Support built on imputed income is common, and it is durable.

One more income question we hear weekly: does a new spouse's income count? Generally no, remarriage does not directly change the formula inputs, but the edges matter, and our guide to new spouse income and child support covers them.

When Courts Depart From the Formula

The guideline number is the presumptive starting point, not always the ending point. Courts can adjust for listed factors: the cost of health insurance and childcare, a child's special educational or medical needs, the parents' relative incomes, travel costs for visitation in long-distance situations, and other specifics. There is also a low-income schedule protecting parents whose earnings cannot sustain the standard percentages.

Two Nevada Supreme Court decisions shape today's deviation fights. Under Martinez v. Martinez (2024), transportation costs between households must be built into the child support order itself rather than handled in a separate order, which matters in every case where a parent has relocated. And under Matkulak v. Davis, 138 Nev. Adv. Op. 61 (2022), an upward deviation based on the relative income of the households has a built-in ceiling: it cannot exceed what the other parent would owe if the roles were reversed. Courts can raise support for high earners, but not without limit.

Adjustments require reasons on the record; if you believe your case justifies one, that argument has to be built, not assumed. Our guide to deviating from the child support guidelines covers how.

What Rides on Top of the Base Number

The formula produces the base obligation. Real orders add shared expenses on top, typically split between the parents in proportion to income:

Health insurance: the order assigns who carries the child's coverage, with the other parent reimbursing their share of the child's portion of the premium. Unreimbursed medical costs get split as well: co-pays, deductibles, dental, vision, therapy. Many Clark County orders use the 30/30 rule. The parent who pays sends proof within 30 days. The other parent then has 30 days to reimburse their share or object in writing. Childcare needed for work or school, and costs tied to a child's special needs, are handled as additions or adjustments. Budget for the guideline number plus your share of these. That is the true monthly picture.

How Long It Lasts, How It Changes, and What Happens If It Is Not Paid

Duration: support generally runs until the child turns 18, or 19 if still in high school. Longer obligations are possible for a child with a disability. It does not end because a parent remarries or disputes how the money is spent. And Nevada does not order college expenses unless the parents agree to them.

Modification: either parent can seek review when three years have passed since the last order. Sooner is possible when gross monthly income changes by 20% or more, or when the custody arrangement materially changes. Modifications run from the filing date, not the layoff date. File promptly when life changes. Job loss is a reason to file, not a defense to nonpayment.

Enforcement: Nevada's tools have teeth. Wage withholding. Tax refund interception. License suspension, liens, contempt, and criminal exposure for large arrears. Unpaid support accrues with interest and does not expire quietly. The full playbook, on both sides of it, lives in our child support enforcement guide.

No Order, Cash Payments, and Arrears: The Expensive Mistakes

The handshake arrangement. Plenty of separated parents run on an informal deal: "I give her $600 a month and we keep the courts out of it." Here is why that arrangement is dangerous for BOTH parents. For the paying parent: without an order, your informal payments may not count, and Nevada law allows a custodial parent to go to court and seek back support reaching up to four years into the past. Parents get blindsided by a filing that turns four years of "we had a deal" into a five-figure back-support judgment, litigated expensively through old bank records and fading memories. For the receiving parent: a handshake is unenforceable. When the payments stop, and they stop, you have no wage withholding, no enforcement tools, nothing but the option to start the court process you skipped, now with a fight attached. An order costs little to establish and protects you both. Get the order.

If one parent has primary custody and there is no order, the obligation does not sleep just because nobody filed. The custodial parent carries the full cost of the child alone, and the noncustodial parent quietly accumulates exposure to a back-support claim. Nobody wins the waiting game; one parent is being underpaid and the other is building a debt they cannot see.

The cash trap. If you pay support in cash, hear this clearly: a payment you cannot prove is a payment you may make twice. Courts and the enforcement system credit what is documented. Cash handed over in a parking lot, with no receipt, no ledger, no record, gets denied as credit routinely, and "she knows I paid" is not evidence. Pay through wage withholding, the state registry, or at minimum a traceable method: check, bank transfer, a payment app with a memo line. If you insist on cash, get a signed, dated receipt every single time. The parent with records wins these disputes; the parent with memories pays again.

Arrears are forever, and they grow. Each missed payment becomes, in effect, a judgment: it accrues interest and penalties, it cannot be retroactively erased by a later court order, it survives bankruptcy, and it follows you across state lines through interstate enforcement. A parent who owes serious back support faces wage garnishment, intercepted tax refunds, suspended licenses, and contempt exposure, and large arrears can bring felony-level consequences. There is no "it's been years, it went away." If arrears exist, on either side of them, the move is the same: get in front of a court and deal with the real number, because time only makes it bigger.

Run Your Own Calculation in Five Steps

Before any consultation, mediation, or kitchen-table conversation, you can get within striking distance of the real number yourself:

• 1. Total each parent's gross monthly income from all sources, before taxes. Annual salary divided by 12; include bonuses, commissions, and side income.
• 2. Apply the tiers for your number of children to the paying parent's income (primary custody) or to both incomes (joint custody).
• 3. If joint physical custody, offset the two results. The higher earner pays the difference.
• 4. Layer the adjustments: who carries health insurance, who pays childcare, any special needs, the low-income schedule if it applies.
• 5. Pressure-test the result in our Nevada child support calculator, which runs the tiers and brackets for you. For the official state resources, Nevada's Division of Welfare and Supportive Services maintains the guidelines documentation, and the Nevada Courts Self-Help Center publishes the court forms and worksheets.

That number is your baseline for every conversation that follows. Demands far above it, and offers far below it, both have to justify themselves against the guideline.

The Myths, Retired

"If they don't pay, I can withhold the kids." And its twin: "if they withhold the kids, I can stop paying." Both wrong, and this pair does more damage in Clark County than any other myth. Child support and parenting time are separate court orders with separate remedies. A parent who withholds the child over unpaid support has just violated a custody order, converting themselves from the wronged party into a violator, and handing the nonpaying parent a defense and a counterattack. A parent who stops paying because visits are being blocked has done the same in mirror image: the arrears accrue anyway, with interest, while the real remedy sat unused. Unpaid support gets fixed through enforcement. Blocked parenting time gets fixed through our custody order violations playbook. Never trade one violation for another; courts punish whoever they catch, and they usually catch both.

"There's a standard amount per kid." No. Two parents of one child can owe $480 and $1,480 under the same formula, because the formula runs on income, not headcount. Anyone comparing their number to a coworker's is comparing incomes, custody schedules, and adjustments they cannot see.

"50/50 custody means no child support." Usually false. The offset only zeroes out when incomes are close; the higher earner pays the difference even at perfectly equal time. Parents who fight for 40% of overnights purely to trigger the offset also find that judges recognize schedule-shopping when the calendar does not match real life.

"We can just agree to no child support." Not by yourselves. Support belongs to the child, not to either parent, so a private waiver does not bind anyone. Parents can stipulate to a different number, but a judge has to approve it, and any later modification runs on the current guidelines regardless of the old deal.

"Support covers only food and clothes, so it should be tiny." Nevada treats support as the child's share of both parents' standard of living: housing, transportation, school life, activities. That is why it scales with income, and why insurance, unreimbursed medical, and childcare ride on top of the base number rather than being buried inside it.

"It all ends when the child turns 18." The ongoing obligation ends at 18, or 19 if still in high school, but arrears survive the child's birthday intact, with interest, and remain fully enforceable. Aging out of the order is not aging out of the debt.

"If I move out of state, they can't touch me." Interstate enforcement is a solved problem. Support orders follow you across state lines, wage withholding reaches out-of-state employers, and the tools, license suspension, tax intercepts, contempt, work from anywhere. Distance adds inconvenience, not immunity.

Three Mistakes to Avoid

Negotiating without the number. The formula is public. Walking into mediation without knowing the guideline amount means negotiating blind against someone who did the math. Run the calculator first; five minutes changes the conversation.

Hiding or minimizing income. Support runs on sworn financial disclosures. Understated income that surfaces later, and it surfaces, costs credibility, can reopen the number, and can bring sanctions.

Treating the order as permanent. Support is modifiable when circumstances change substantially, and Nevada allows periodic review. Job loss, big raises, and changed custody schedules all support a modification, but only from the date you file, not the date life changed. Waiting costs real money. The full picture lives in our Nevada child support guide.
