The complete text and charts of the Guidelines is more than 100 pages (in full-size type). In New Jersey, the Guidelines are set by Court Rule. The Rule number is 5:6A (the actual charts are an Appendix to the Rule, in the back of the Court Rules Book). Most major libraries in the State have a copy that you can read or photocopy. All law libraries in the courthouses have public copies. The Guidelines are also available on the Internet at https://www.njcourts.gov/attorneys/assets/rules/r5-6a.pdf.
The tax calculation method is assumed to be IX-H. If the Gross Taxable Income of the CP or NCP includes non-FICA or business income items, then the calculated amount will not include accurate taxation. You must run a full guideline to get the proper amount.
