Extension of Time to File
An extension of time is granted only to file your New Jersey income tax return. There is no extension of time to pay tax due. We will notify you only if your extension request is denied, but not until after your return is actually filed. Penalties and interest are imposed whenever tax is paid after the original due date.
Six-Month Extension You may receive a six-month extension of time to file your New Jersey resident income tax return. An application for an extension of time to file is accepted only if at least 80% of the tax liability computed on Line 42 of your Form NJ‑1040 when filed is paid in the form of withholdings, estimated, or other payments by the original due date, and
1. Federal extension filed. A copy of your Federal Application for Automatic Extension is enclosed with your final return and the oval at the top of the NJ-1040 is filled in (or your confirmation number is entered in the space provided at the top of Form NJ-1040 if the extension application or payment was filed online or by phone); or
2. No Federal extension filed. You file a request for a six-month extension on Form NJ-630, Application for Extension of Time to File New Jersey Gross Income Tax Return, by the original due date of the return. Taxpayers who file Form NJ-630 will not receive an approved copy. We will notify you only if your request is denied, but not until after your return is actually filed.
Note: If a Federal extension is filed, Form NJ-630 must still be filed by the original due date if you are required to make a payment to satisfy the 80% requirement.
