Who Pays Child Support With 50/50 Custody in New Jersey?

New Jersey answers the 50/50 question with paperwork: which worksheet does your case run on? The state maintains two. Equal overnights can satisfy the time part of the shared-parenting test, but time alone does not guarantee that the final order may use the shared worksheet.

Two worksheets, one dividing line

New Jersey computes support on weekly net income, converted through the Appendix IX-H tax tables under the IX-B instructions, against the Appendix IX-F schedule of basic obligations. What varies is the worksheet wrapped around that schedule:

• The sole parenting worksheet (IX-C) applies when the shared-parenting requirements are not met. A parenting-time credit can require additional household facts and is not automatic.
• The shared parenting worksheet (IX-D) begins with the substantial equivalent of two or more qualifying overnights a week, at least 28 percent of the year, plus separate living accommodations for the children. It builds in both parents’ fixed costs and scales variable costs by time.

A true 50/50 split clears the overnight percentage, but the shared result still must pass the primary-household test. The final 2026 order cannot use that result when the primary household’s net income (including other household members and means-tested income) plus the order falls below the published threshold for its household size. In that situation, the guidelines direct the court to calculate the sole-parenting award.

Why this page does not publish a universal 50/50 number

Two families with the same parental incomes and overnights can take different paths because the shared test also asks for household size, income from other adults in the primary household, means-tested household income, and separate accommodations. Taxes matter too: the current IX-H tables convert gross income to the weekly net figures used by the worksheet. A comparison that omits those facts can look precise while selecting the wrong worksheet.

The calculator therefore asks for the shared-household facts and refuses a shared result that fails the operative threshold. It also labels results as estimates because you enter weekly net income directly instead of having this site reproduce the current IX-H tax tables.

So who pays?

Often the higher earner, but the worksheet decides the direction. New Jersey’s shared worksheet compares contributions weighted by income and time; it can even produce a negative alternate-parent obligation, making the primary parent the payer. The self-support reserve and primary-household test can then change which result may be used. If you want the state-by-state version of this pattern, see do you pay child support with 50/50 custody.

Details that move New Jersey numbers

• Net, not gross. New Jersey uses guideline weekly net income. That is not necessarily a paycheck’s take-home amount; the official tax-table instructions and allowed adjustments matter.
• The overnight count is factual, not aspirational. The shared worksheet’s discounts scale with the actual schedule. Count a proposed calendar precisely with the parenting time calculator before assuming IX-D treatment; 103 whole nights is the first annual count at or above 28 percent, while 102 is below.
• Add-ons ride along. Use net work-related child care from the current June 2026 Appendix IX-E worksheet, after federal and New Jersey credits, plus the children’s health-insurance cost. They are divided by income shares on top of the basic figure.
• Judges can deviate. The guideline is a presumption. Courts can adjust where a worksheet result would be unjust, and self-support reserves protect low-income parents at the bottom of the schedule.
