The deadline for filing returns, making payments, or taking any other action is extended for 180 days after the individual leaves the combat zone, or 180 days from the last day of any continuous qualified hospitalization for an injury sustained in the combat zone. See Special Provisions
for more information.
You may receive a six-month extension of time to file your New Jersey Income Tax return if you have paid at least 80% of your tax liability on the NJ-1040 (Line 42) or NJ-1040NR (Line 40) through withholdings, estimated payments, or other payments by the original due date, and
You must also file Form NJ-630 by the original due date if you need to make a payment to meet the 80% requirement.
Civil union partners filing a joint return must either provide copies of the federal extension application (or confirmation number) for both partners, or they must file Form NJ-630.
