New Jersey Child Support Laws (2026): Guidelines & Calculator

New Jersey calculates child support under the income shares model, governed by Court Rule 5:6A. Courts combine both parents' net incomes, look up the obligation in the Appendix IX-F schedule, and split the amount proportionally. Support terminates automatically at age 19 but may continue to age 23 for education. Use the New Jersey child support calculator below to estimate a guideline amount, or open the full-page New Jersey child support calculator for a detailed breakdown.

A New Jersey court's authority to order child support comes from N.J.S.A. 2A:34-23 in matrimonial cases and, in parentage cases, from N.J.S.A. 9:17-53(e), which directs the court to apply the child support guidelines. The calculation method itself is set by Court Rule 5:6A and the New Jersey Child Support Guidelines in Appendix IX of the New Jersey Rules of Court rather than by statute. The state uses an income shares model, meaning both parents' incomes factor into the support calculation. The goal is to approximate what parents would have spent on their children if the family had stayed together.

• Be treated professionally and with respect
• Pay or receive timely payments
• Appeal decisions or request order reviews
• Be notified of actions affecting the case
• Request a child support review every three years

Establishing Paternity in New Jersey

Before a court can order child support, paternity may need to be established. New Jersey recognizes three ways to do this:

• Presumption of marriage: A child born during a marriage is presumed to be the husband's child
• Certificate of parentage: A voluntary acknowledgment signed by both parents, typically at the hospital after birth
• Court order: A judicial determination or complaint filed with DHS (may include genetic testing)

Establishing paternity gives both parents legal rights and responsibilities. It also allows the child to access benefits such as health insurance, Social Security, and inheritance rights. For paternity questions, payment history, or court dates, call 1-877-NJKIDS1.

How Child Support Is Calculated in New Jersey

New Jersey uses an income shares model under Court Rule 5:6A and Appendix IX-A of the New Jersey Rules of Court. Both parents' incomes are combined, and the total child support obligation is divided proportionally based on each parent's share of that combined income. For example, if one parent earns 60% of the combined net income, that parent is presumptively responsible for 60% of the child support obligation.

Determining Income

The court considers all sources of income when calculating support, including:

• Wages, salaries, and bonuses
• Self-employment income
• Investment income and dividends
• Pension and retirement income
• Social Security and disability benefits
• Workers' compensation
• Unemployment benefits
• Alimony received from any source

If a parent is voluntarily unemployed or underemployed, the court may impute income based on that parent's earning capacity, education, and work history.

Step-by-Step Calculation

The basic calculation process follows these steps:

1. Determine each parent's weekly gross income
2. Subtract mandatory deductions (taxes, union dues, mandatory retirement contributions) to arrive at net income
3. Combine both parents' net incomes
4. Look up the combined income in the Appendix IX-F Schedule of Child Support Awards for the appropriate number of children
5. Divide the basic obligation proportionally based on each parent's percentage of combined income
6. Add adjustments for child care costs, health insurance premiums, and other predictable expenses

Use the official QuickCalc calculator for estimates based on your specific situation, or try the New Jersey child support calculator on this page. Any guideline estimate has two hard limits: it becomes a floor rather than a full award once combined net income passes the ceiling described below, and it does not apply at all to a child who has reached majority and finished secondary school.

Incomes Above the Guidelines Ceiling

The Appendix IX-F schedule stops at a combined net income of $187,200 per year. Under Appendix IX-A, paragraph 20(b), if the parents' combined net income is more than $187,200, the court applies the guidelines up to $187,200 and then supplements that guidelines-based award with a discretionary amount based on the remaining family income and the factors listed in N.J.S.A. 2A:34-23. The maximum guidelines award is therefore the minimum award for a high-income family, not a cap, and the appendix directs that a court shall not extrapolate the Appendix IX-F schedules, statistically or by adding amounts from different income ranges, beyond that dollar limit.

Self-Support Reserve

As of January 1, 2026, the self-support reserve is $460 per week, representing 150% of the federal poverty guideline for one person. This increased from $451 per week in 2025. If an obligor's net income after deducting their share of child support falls below this threshold, the court will carefully review the obligor's income and living expenses. The goal is to determine the maximum amount of support that can reasonably be ordered without denying the obligor the means of self-support at a minimum subsistence level.

Child Support Worksheets

New Jersey uses three primary worksheets depending on the custody arrangement:

The Appendix IX-F Schedule provides the basic child support award amounts based on combined parental income and the number of children. The schedule runs only to a combined net income of $187,200 per year; above that ceiling the court supplements the top schedule amount under Appendix IX-A, paragraph 20(b).

Grounds for Deviation

Courts may deviate from the guidelines when a strict application would be unjust or inappropriate. Factors that may justify a deviation include:

• Unreimbursed medical or dental expenses exceeding normal costs
• Special needs of a disabled child
• Prior support orders for other children
• The ages of the children
• Private or parochial school tuition and expenses
• Extraordinary travel costs for parenting time
• Significant assets or debts of either parent

A combined net income above the top of the Appendix IX-F schedule is handled differently from a deviation. The court applies the schedule up to $187,200 and adds a discretionary supplement under N.J.S.A. 2A:34-23, rather than departing from the guidelines.

2025 and 2026 Updates to New Jersey Child Support Guidelines

New Jersey updated its child support provisions several times between 2025 and 2026, reflecting both legislative changes and routine guideline adjustments.

Equitable Outcomes in Child Support Collection Act (January 2025)

Governor Murphy signed the Equitable Outcomes in Child Support Collection Act (P.L. 2025, c.5) on January 30, 2025. This law provides that child support obligations and unpaid arrears owed to the Division of Child Protection and Permanency (DCPP) for maintenance costs while a child was in state care are deemed null and void. The law applies only to support owed to DCPP; it does not affect support owed to a custodial parent.

Annual Guideline Updates (June 2025)

Effective June 1, 2025, the New Jersey Supreme Court adopted annual updating amendments to Appendices IX-A, IX-B, and IX-H. These updates included revised considerations for using the guidelines, updated sole and shared parenting instructions, and new combined tax withholding tables.

Updated Appendix IX-F Schedule (September 2025)

Effective September 1, 2025, the Schedule of Child Support Awards was revised based on Dr. David A. Macpherson's 2024 economic analysis of consumer expenditure data. The updated schedule generally results in higher support amounts. For example, in a two-child case where the custodial parent earns $1,045 per week net and the non-custodial parent earns $2,007 per week, support increased from $219 to $276 per week under the new schedule.

Annual Guideline Updates (June 2026)

Effective June 1, 2026, the New Jersey Supreme Court adopted additional annual updating amendments to Appendices IX-A, IX-B, IX-E, and IX-H. These updates also incorporated the self-support reserve increase to $460 per week effective January 1, 2026.

Updated Case Information Statement (CIS)

The Case Information Statement (CIS) was also updated in 2025 with several new categories:

• New Schedule D for seasonal and occasional expenses (snow removal, lawn care, vehicle registration)
• New asset categories: cryptocurrencies, children's accounts, income tax carryover losses
• New liability categories: tax liabilities
• Dedicated line for streaming services and subscriptions

How to Modify Child Support in New Jersey

To modify child support, you need to file a written motion demonstrating that important facts or circumstances have changed since the order was issued. Court Rule 5:5-4 governs modification motions.

Types of Modification Motions

• Motion to terminate or continue support
• Motion to increase or decrease payments
• Motion to enforce an existing order

Required Forms

• Request to Modify Court Order
• Request/Enforce Court Order Form and Instructions

Factors Courts Consider for Modification

When evaluating a modification request, courts look at:

• Medical, educational, and financial needs of the child
• Parental income from all sources
• The child's need for higher education
• Each parent's earning capability and employment history
• Changes in the cost of living
• Changes in custody or parenting time arrangements
• Any other relevant factors under the New Jersey guidelines

Either parent may request a review of the support order every three years through DHS, even without showing a change in circumstances.

Child Support Enforcement in New Jersey

New Jersey uses a computerized system to record and monitor child support payments. Under N.J.S.A. 2A:17-56.8, all court-ordered child support is subject to mandatory income withholding, meaning payments are typically deducted directly from the obligor's paycheck. The state has several additional enforcement tools available when a parent falls behind on payments. See the New Jersey Courts child support enforcement page for full details.

Enforcement Tools

Contempt of Court

A custodial parent can petition the court to hold the paying parent in contempt for non-payment. Key points about contempt proceedings in New Jersey:

• The court can order the accused to pay the accusing party's attorney fees
• Penalties range from fines (minimum $50) to jail time
• The burden falls on the accused to prove inability to pay
• Denial of parenting time may be raised as a defense in contempt proceedings
• Errors in the support order may also serve as a defense

Contempt motions can also address denial of court-ordered parenting time, though parenting time and child support are legally separate issues.

When Does Child Support End in New Jersey?

Under N.J.S.A. 2A:17-56.67 (effective February 1, 2017), child support in New Jersey terminates by operation of law when the child reaches age 19, without requiring a court order. New Jersey changed the presumptive age of termination from 18 to 19 when this statute took effect.

Continuation Beyond Age 19

A court may order support to continue past age 19 if the child is:

• Still enrolled in high school or a secondary education program
• Enrolled in a post-secondary education program (college or vocational school)
• Mentally or physically disabled and unable to support themselves

Support ordered beyond age 19 cannot exceed the child's 23rd birthday unless a parent demonstrates that the child has a severe mental or physical incapacity that causes ongoing financial dependence.

Support past majority is not calculated with the guidelines schedule. Appendix IX-A, paragraph 25, provides that the guidelines shall not be used to determine a support obligation for a child who has reached majority (18 years of age) and who is no longer enrolled in high school or other secondary education, because the Appendix IX-F estimates cover children from ages zero through 17. Once a child reaches majority and completes secondary education, any support obligation the court finds appropriate is determined under N.J.S.A. 2A:34-23 and existing case law instead.

College Contribution

New Jersey is one of the few states where courts can order divorced or separated parents to contribute to a child's college expenses. Under the factors established in Newburgh v. Arrigo (1982), courts consider:

• Whether the parent would have contributed to college costs if the family remained intact
• The parent's ability to pay
• The child's aptitude and commitment to education
• Financial resources of both parents and the child
• Availability of financial aid, grants, and loans
• The relationship between the child and the paying parent

College contribution is separate from the basic child support obligation and is evaluated on a case-by-case basis under N.J.S.A. 2A:34-23 and case law, not under the Appendix IX-F schedule.

Emancipation

Emancipation is a legal event distinct from termination of support. A child may petition for emancipation if they are:

• At least 16 years old
• Financially independent
• Capable of handling their own affairs, including housing

Emancipation grants the right to obtain employment, sign leases, and live independently without parental consent. It does not grant age-restricted privileges like purchasing alcohol. Joining the U.S. military is another recognized path to emancipation.

Termination of Parental Rights

Voluntarily terminating parental rights is typically only available when placing a child for adoption. This action ends future financial obligations but does not eliminate existing child support arrears. Court approval is required.
