How New Jersey child support law works
New Jersey’s Appendix IX contains the guideline instructions, schedules, and worksheets. The Supreme Court adopted annual updates to Appendices IX-A, IX-B, IX-E, and IX-H effective June 1, 2026, including the tax and child-care materials used with the calculation.
Sources: Appendix IX-B: worksheet instructions.
How the guideline is calculated
- Choose the sole- or shared-parenting worksheet using the guideline instructions for the family’s arrangement.
- Convert income and deductions to weekly amounts. Include the worksheet’s treatment of taxes, alimony, and other dependents to derive net income.
- Use the parents’ combined net income and child count to find basic support, then allocate by income share.
- Add eligible child-care, child health-coverage, and other expenses; apply payment credits and any shared-parenting adjustments.
An older blank form can still appear on the court’s website. Read it together with the current Appendix IX instructions and annual updates, especially when calculating taxes or net child-care costs.

Documents that make the worksheet more useful
- Weekly income figures and the records needed to establish tax treatment and allowed deductions.
- The parenting arrangement and overnight calendar, plus documentation of other dependents.
- Child-care costs, the child’s share of health premiums, and expenses entered on the worksheet.
Keep the source document beside each figure you enter. If a number is uncertain, note what still needs to be confirmed before relying on an estimate.
What this site’s worksheet covers
The educational guide and official resources are available now. Our New Jersey workflow collects both parents’ financial information and produces a printable accounting. It does not calculate a child-support amount; the official state calculator linked on this page does.
How New Jersey cases actually get to a number
Complete the net-income lines first—New Jersey’s deductions are specific. Then choose Sole-Parenting or Shared-Parenting based on the overnights. Appendix IX-A explanations are part of the guideline, not optional reading.
New Jersey’s child-support guidelines (Court Rules Appendix IX) are an income-shares system with Sole-Parenting and Shared-Parenting worksheets and a detailed net-income computation. 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 New Jersey
The shared-parenting worksheet generally applies when the non-custodial parent has the children overnight at least 28 percent of the year (with the current rule’s exact test). That is a New Jersey-specific threshold.
Costs New Jersey usually treats separately
- Child-care costs
- Health-insurance premiums
- Predictable and recurring unreimbursed medical expenses
- Other Appendix IX add-ons
When New Jersey courts leave the guideline
Appendix IX-A lists deviation factors. High income above the schedules, a child’s own income, and extraordinary travel are typical. The worksheet still comes first.

Questions specific to New Jersey
Sole or shared worksheet?
Shared parenting in New Jersey is an overnight-percentage test. Below the threshold, stay on the sole-parenting worksheet.
Are taxes handled on the worksheet?
Yes. New Jersey’s net-income computation is detailed. Do not paste take-home pay into the combined-income line.
Is this site’s New Jersey calculator live?
The New Jersey page is a sourced guide and financial intake. Use Appendix IX for a filing-ready calculation until a numerical module is released.

Frequently asked questions
Are all expenses included in the basic support schedule?
No. The sole-parenting worksheet has separate lines for net work-related child care, the child’s health-insurance share, qualifying unreimbursed health care, and court-approved extraordinary expenses. It then credits specified payments.
Does this guide also calculate alimony?
No. These steps concern child support. A worksheet may consider an existing spousal-support payment when its rules allow, but it does not determine a new alimony award.
Can I file the financial intake as the state worksheet?
Our intake is a preparation aid. Use the official state forms and the instructions for your court when submitting a proposed support calculation.
