How can I file an extension for my New Jersey taxes?
To file an extension for your New Jersey state income tax return, you must submit Form NJ-630, Application for Extension of Time to File New Jersey Gross Income Tax Return. This form must be filed (postmarked) no later than the original due date of your return, which is typically April 15. For the 2025 tax year, the deadline to file Form NJ-630 is April 15, 2026.
How to File Form NJ-630
- Online Filing: You can file Form NJ-630 online until 11:59 p.m. on April 15, 2026, through the New Jersey Division of Taxation website at nj.gov/treasury/taxation.
- Payment with Extension: If you are required to make a payment with your online extension application, payment must be made by e-check or credit card.
- Software Assistance: If you are using tax preparation software, you can add Form NJ-630 by navigating to 'Tax Tools' > 'Extension' > 'File State Extension' > select 'New Jersey' and follow on-screen instructions.
Important Notes
- Filing Form NJ-630 grants you an additional 6 months to file your return (until October 15 for most taxpayers).
- An extension to file is not an extension to pay. You must estimate and pay any tax owed by the original due date (April 15) to avoid penalties and interest.
- If you filed a federal extension (Form 4868), you may check the box on Form NJ-1040NR or enter your confirmation number if filed online or by phone.
