New Jersey Tax Extension Requirements

What is an Extension?

An extension gives you more time to file your state tax return without penalties. But an extension to file doesn’t provide an extension to pay. The state requires you to pay at least 80% of your taxes by the original deadline to qualify for an extension. In addition, you'll also avoid a late payment penalty.

New Jersey Tax Extension Quick Facts:

• 6 months for individual returns (Forms NJ-1040, NJ-1040NR, NJ-1080C)
• Fiduciary returns (Forms NJ-1041, NJ-1041SB) get 5.5 months.
• New Jersey accepts the federal tax extension.
• If you are not filing a federal extension, file the state extension application (Form NJ-630) by the original deadline.
• If you paid at least 80% of your taxes through withholdings, estimated payments, or with the extension application, the extension will be automatically granted.
