To receive an extension, at least 80% of the tax due must be paid by the original return due date. If at least 80% of the tax liability is paid through withholding, estimated tax, and other payments, a taxpayer can receive an automatic six-month extension by filing federal Form 4868 with the IRS and attaching a copy to the New Jersey return. If no federal extension is filed, a taxpayer can request a six-month extension to October 15 by mailing in Form NJ-630, Application for Extension of Time to File New Jersey Gross Income Tax Return, or filing online. If the taxpayer is required to make a payment with the extension to satisfy the 80% requirement, file Form NJ-630 even if the federal Form 4868 is filed with the IRS.
Members of the military not able to file on time due to their service automatically receive a six-month extension. Members serving in a combat zone or qualified hazardous duty area have 180 days after leaving the combat zone or qualified hazardous duty area to file. Those hospitalized outside the state because of serving in a combat zone or qualified hazardous duty area have 180 days from the time of leaving the hospital, combat zone, or hazardous duty area, whichever is later, to file a return. Enclose an explanation with the return when filed.
To access the New Jersey Form NJ-630, from the main menu of the New Jersey state return select:
- Miscellaneous Forms

Note: Electronic filing is not supported for the state extension in ProWeb. The federal extension payment may be sent electronically, however the state extension will have to be mailed.
