State of New Jersey
Personal Income Tax Extensions
2019 Tax Return Due Date Remains April 15, 2020 as of 3/28/20
New Jersey Filing Due Date: NJ personal income tax returns are due by April 15 — or by the 15th day of the 4th month following the end of the taxable year (for fiscal year filers).
Extended Deadline with New Jersey Tax Extension: New Jersey offers a 6-month extension, which moves the personal filing deadline from April 15 to October 15 (for calendar year filers).
New Jersey Tax Extension Form: To request a New Jersey extension, file Form NJ-630 by the original due date of your return. Form NJ-630 can be sent in by paper mail, or you can submit it electronically using New Jersey’s online filing service: www1.state.nj.us/TaxPortal/Ind
New Jersey Extension Payment Requirement: An extension of time to file is not an extension of time to pay your New Jersey gross income tax. All state tax payments are due by the original deadline of the return. Any NJ tax that hasn’t been paid by the proper due date will be subject to interest and penalties. Furthermore, your New Jersey tax extension will only be approved if you’ve paid at least 80% of your state tax liability by the original April 15 deadline. You can make an extension payment for your NJ income tax with Form NJ-630, or pay electronically through New Jersey’s online payment service: www1.state.nj.us/Portal/IndTax
New Jersey Tax Extension Tip: If you obtain a Federal tax extension (IRS Form 4868), you will automatically receive a New Jersey tax extension. In this case, you do not have to file Form NJ-630 unless you need to make a New Jersey extension payment.
