New Jersey Child Support Guide 2026: How the Guidelines Calculate Your Amount
Parents facing a support case in New Jersey usually want one number: how much will the court order? A statewide guideline formula turns both parents’ incomes and the number of children into a presumptive weekly amount. This guide explains how it works. Run your own figures in the free New Jersey child support calculator.
How is child support calculated in New Jersey?
New Jersey adds both parents’ weekly net incomes together, looks up the basic support obligation for that combined income and number of children on the Appendix IX-F schedule, then charges the paying parent their percentage share of the total. Child care and health insurance costs are added and split by the same percentages.
The rules sit in Appendix IX-A of the New Jersey Court Rules. The model is called “income shares”: it estimates what parents in one household would spend on their children, then divides that cost when they live apart. One New Jersey quirk catches people out — everything runs in weekly amounts, not monthly, because support is calculated and usually paid weekly.
What is the New Jersey child support schedule for 2026?
The Appendix IX-F Schedule of Child Support Awards, revised effective September 1, 2025, lists a weekly basic obligation for combined net incomes from $180 to $3,600 and one to six children — for example, $420 a week for two children at $1,500 of combined weekly net income.
The full schedule runs to 343 rows in $10 income steps, and it is rebuilt from fresh consumer-spending research each revision cycle — the 2025 version rests on an analysis of 2013–2019 Consumer Expenditure Survey data. Older calculators using the pre-2025 schedule will be off. Above the top of the schedule, the obligation cannot be set lower than the highest schedule amount, but the court must add more, as explained below.
Does New Jersey use gross or net income for child support?
New Jersey uses weekly net income. Each parent starts with gross income from all sources, then subtracts income taxes, mandatory union dues, mandatory retirement contributions, support paid for other children, and, where it applies, a theoretical obligation for other dependents, following Appendices IX-A and IX-B.
Courts work out the tax deduction from the Appendix IX-H withholding tables, which vary with filing status and exemptions — so two parents on the same salary can land on different net incomes, and bonuses and overtime count as income too. If a parent is voluntarily unemployed or underemployed without just cause, the court can use imputed (potential) income instead; a parent’s incarceration, on its own, may not be treated as voluntary unemployment.
How much is child support in New Jersey for two children?
Take parents earning $1,500 and $800 gross per week with two children, $150 of weekly child care and a $60 children’s health premium. Their estimated net incomes are about $1,225 and $685 — a combined $1,910. The schedule obligation is $471 a week, and the higher earner pays roughly $412 a week.
That $412 a week works out to about $1,785 a month. Your number moves with each input — higher child care raises it, and substantial overnight time changes the calculation, as the next sections explain. Courts use the official withholding tables to fix net income rather than estimates, so treat any online figure as a close preview rather than the exact order.
Does parenting time reduce child support in New Jersey?
Yes, in two stages. On the sole-parenting worksheet the paying parent gets a credit for the variable costs of their overnights — 37% of the basic award multiplied by their share of overnights. At roughly 28% of overnights or more, the shared-parenting worksheet may apply instead, with a larger adjustment.
The thinking is that a parent with regular overnights spends directly on food and transportation while the children are with them — the “variable” slice of child-rearing costs, fixed at 37% by the guidelines. A parent with every-other-weekend time (about 14% of overnights) sees a credit of roughly 5% of the basic award; it grows in proportion to time. The credit is a ceiling, not an entitlement: the court may check that the expenses are really incurred, and where the receiving household is poor, the credit becomes discretionary.
What is shared parenting in a New Jersey child support case?
Shared parenting applies when the alternate-residence parent has the children for about two or more overnights a week, keeps separate living accommodations for them, and a parenting plan is filed or ordered. The formula then splits spending into fixed, variable and controlled costs and credits the duplicated housing costs of two homes.
The spending split is 38% fixed (housing), 37% variable (food and transport) and 25% controlled (clothing, personal care, entertainment). The primary parent’s housing costs stay whole; the other parent’s are counted at twice their share of overnights. Controlled costs are assigned to the primary parent and shared by income only, never by time. One safeguard matters: if the primary household’s income plus the shared award would drop below twice the poverty guideline, the shared award cannot be used at all and a sole-parenting award is calculated instead.
What happens at very high or very low incomes in New Jersey?
Above $3,600 a week of combined net income ($187,200 a year), the top schedule amount is only a minimum — the court adds a discretionary amount under the statutory factors. At the bottom, awards run from $5 a week, and a self-support reserve of $451 a week can reduce what a low-income parent pays.
The reserve is 150% of the poverty guideline for one person, and it bites only when two conditions coincide: paying the award would push the paying parent below $451 a week, and the receiving parent stays above that line after their share of the award. The court then reviews living expenses and sets the most that can reasonably be ordered. And whatever the incomes, a fixed dollar amount is always ordered — there is no such thing as a guideline award of zero purely because income is low.
Are child care and health insurance added to New Jersey child support?
Yes. Net work-related child care costs, the children’s share of a health insurance premium, predictable unreimbursed medical costs over $250 per child per year, and court-approved extraordinary expenses are added to the basic obligation and divided between the parents in proportion to their net incomes.
Two details catch parents out: child care totals are reduced by the federal child care tax credit before they are split, and only the marginal cost of covering the children counts toward the premium — not the parent’s whole policy. The schedule amount already includes the first $250 per child per year of unreimbursed health costs, which is why only predictable costs above that line are added. Amounts the paying parent already covers directly are credited against the order.
Can a New Jersey court order more or less than the guideline amount?
Yes. The guideline amount is a rebuttable presumption, and Appendix IX-A lists factors that can justify an adjustment, from a child’s special needs to other support obligations. Above the income cap an extra amount is mandatory, set under the factors in the statute, N.J.S.A. 2A:34-23.
Other listed adjustment factors include equitable distribution of property, the tax consequences of the order, and expenses such as private school tuition or visitation transportation. Deviations below the cap are the exception — most orders land on the guideline figure, so a careful estimate is a realistic preview of the outcome.
How can you estimate your own New Jersey child support?
Gather both parents’ weekly pay, the number of children, the paying parent’s overnights per year, your weekly child care cost and the children’s health premium, and enter them in the New Jersey child support calculator. It estimates net incomes, applies the current schedule and income shares, and handles both parenting worksheets.

Frequently Asked Questions
Is child support taxable in New Jersey?
No. It is not taxable income for the parent who receives it, and the parent who pays it cannot deduct it — that is the federal rule, and New Jersey follows it.
Can New Jersey child support be modified?
Yes. Either parent can ask the court to modify an order after a substantial change in circumstances — a job loss, a raise, a change in parenting time, or an update to the guidelines themselves, such as the revised schedule that took effect on September 1, 2025.
What counts as income for New Jersey child support?
Gross income from all sources: wages, bonuses, overtime, commissions, self-employment income, pensions, and most other regular receipts. Means-tested benefits such as TANF, SNAP and SSI do not count. Government benefits a child receives because of a parent’s disability or retirement do count in that parent’s income, and are then credited against that parent’s obligation.
What if a parent has children from another relationship?
A theoretical support obligation for those other legal dependents adjusts the parent’s income before the calculation for the children in the case (Appendix IX-A, paragraph 10(a)). Stepchildren are not legal dependents for this purpose unless a court has found the parent legally responsible for them.
Who pays child support if both parents earn the same?
With primary custody and equal incomes, the non-custodial parent still pays their 50% share — the custodial parent’s share counts as spent directly on the children. Under shared parenting with equal incomes and exactly equal time, the formula can still leave a modest payment toward the primary parent, because controlled expenses (clothing, personal care, entertainment) are assigned to that parent and housing costs are duplicated across two homes.
