To apply for an extension for NJ 1040, use form NJ-630. See below for more information:
There is no extension of time to pay tax due only to file. Penalties and interest are imposed whenever tax is paid after the original due date. To be eligible for an extension, you must have paid at least 80% of the tax liability calculated on the New Jersey Income Tax return when filed. The 80% can be paid through withholdings, estimated payments, or a payment made with the extension application by the original due date. If the 80% requirement is not met, the extension will be retroactively denied, and penalty and interest will be imposed from the original due date of the return.
You must file this NJ-630 application if:
1. You are applying for an extension of time to file a New Jersey Income Tax return but you are not applying for a federal extension; or
2. You are applying for both a federal and a New Jersey extension and are required to remit payment to the New Jersey Division of Taxation by the original due date of the return in order to have at least 80% of your actual tax liability (as calculated on your New Jersey Income Tax return when filed) paid.
You do not need to submit this NJ-630 application if:
1. You have paid at least 80% of your final tax liability by the original due date, and
2. You have applied for an automatic extension of time to file for federal purposes and you enclose a copy of the federal Application for Automatic Extension (if filed by paper) with the final New Jersey return when filed.
