Important Notes for New Jersey

  • New Jersey uses the Income Shares model based on both parents' combined net income (after taxes, FICA, and mandatory deductions).
  • The Appendix IX-F schedule was revised effective September 1, 2025 (Dr. Macpherson's 2024 Rothbarth analysis). The schedule is capped at $3,600 per week combined net income (approximately $15,600 per month).
  • Effective June 1, 2026: updated tax withholding tables (Appendix IX-H), poverty guidelines, and childcare cost eligibility reduced from age 15 to age 13 (unless the child has special needs).
  • The self-support reserve is approximately $460/week (150% of the 2026 federal poverty guideline of $15,960/year for one person).
  • New Jersey accounts for the Parent of Alternate Residence (PAR) time through a shared parenting adjustment when the PAR has the child for at least 28% of overnights.

Example Calculation

Scenario: Parent A earns $5,000/month, Parent B earns $3,000/month, 2 children.

Step 1: Combined income: $8,000

Step 2: Parent A's share: $5,000 / $8,000 = 62.5%

Step 3: Look up basic obligation for $8,000 combined and 2 children.

Step 4: Multiply by Parent A's share (62.5%).

Adjustments for health insurance, child care, and parenting time may apply.

New Jersey Child Support FAQ

How is child support calculated in New Jersey?
New Jersey uses the Income Shares model based on combined net income. Both parents' net incomes (after taxes, Social Security, and Medicare) are combined, and a basic support obligation is determined from the guidelines schedule. Each parent pays their proportional share. Adjustments are added for health insurance, child care, and other costs.
What is net income for New Jersey child support?
Net income in New Jersey for child support purposes is gross income minus federal, state, and local income taxes, Social Security and Medicare taxes (FICA), mandatory union dues, mandatory retirement contributions, and prior child support or alimony orders. Voluntary deductions like 401(k) contributions are generally not subtracted.
What is the maximum child support in New Jersey?
The New Jersey guidelines schedule applies to combined net weekly incomes up to $3,600 (approximately $15,600/month or $187,200/year net). For incomes above this cap, the court uses the guideline amount at $3,600/week as a floor and has discretion to order additional support based on the child's reasonable needs and the parents' financial ability.
How does shared parenting time affect child support in New Jersey?
When the Parent of Alternate Residence (PAR) has the child for at least 28% of overnight time (approximately 2 nights per week), New Jersey applies a shared parenting adjustment. This adjustment reduces the basic support obligation to account for the PAR's increased direct spending on the child during their parenting time.
How long does child support last in New Jersey?
In New Jersey, there is no specific statutory age at which child support automatically ends. The obligation generally continues until the child is emancipated. Emancipation typically occurs when the child reaches 19, but the court considers factors like whether the child is still in high school, attending college full-time, or has a disability. Parents can petition for emancipation or its extension.
