Requests for Extension

If you need more time to prepare your New Jersey tax return beyond the due date of April 15, you may apply for an extension of time to file the return. This is not an extension of time to pay your taxes however. You must have at least 80% of any owed taxes paid no later than April 15, 2026, to avoid a late filing penalty. If you request an extension and have at least 80% of owed taxes in by April 15, the extended due date of the New Jersey tax return is October 15, 2026.

You can file your request for extension online or by printing and mailing Form NJ-630 .

In order for New Jersey to accept your extension, you must:

  • Calculate your total tax due for the tax year. Find your total tax liability on Form NJ-1040, line 45; Form NJ-1040NR, line 42; or Form NJ-1041, line 29;
  • If your withholdings, estimated payments, or other payments do not equal at least 80% of your total tax due, make a payment with your extension application to ensure you have at least 80% paid.

If you do not have at least 80% of your taxes paid by April 15, 2026, we will deny your extension and charge you a late filing penalty.

Provide us with a copy of your federal extension application (or confirmation number from the IRS) when you file your New Jersey tax return.

Civil union partners filing a joint return must either provide copies of the federal extension application (or confirmation number), or they must file Form NJ-630.
