The New Jersey Gross Income Tax Act requires a taxpayer (and spouse/CU partner) to include a social security number or ITIN (Individual Taxpayer Identification Number) on the gross income tax return for identification purposes.
The taxpayer should use the same identification number on the New Jersey gross income tax return that is used for federal income tax purposes.
If you will know your identification number by April 15, you should file your income tax return the same way as you are filing for federal income tax purposes.
If you (or your spouse/CU partner) have applied to the IRS, but have not received a Taxpayer Identification Number by April 15, file the New Jersey income tax return and enclose a copy of Federal Form W-7
(Application for IRS Individual Taxpayer Identification Number) by the due date of the return.
Otherwise, the taxpayer should consider filing an extension of time to file an income tax return
Note: A copy of Form W-7 (or W-7A) cannot be used in place of a valid social security number, ITIN, or ATIN for a dependent.
