Personal Tax Information:

If you were approved for a federal tax extension, then the State of New Jersey will automatically grant you a six month tax extension. If you need to make a state tax payment, you'll need to submit New Jersey Form NJ-630 (PDF). Include a copy of your federal extension (IRS 4868) when you file your state tax return.

Filing an New Jersey tax extension does not grant you extra time to pay any tax balance due. Your balance must be paid by April 15 to avoid possible penalties.

If you already received an approval notification from ExpressExtension, and you don't need to make a tax payment, then you're all done.

Business Tax Information:

The State of New Jersey will automatically grant your business a 6-month tax extension (5 months for estates and trusts) if it was approved for a federal tax extension and there's no tax balance due. However, you will need to submit New Jersey Form CBT-200-T (PDF) if your business needs to make a state tax payment or if it was not approved for a federal extension.

If you do not need to make a tax payment and have received an approval notification from ExpressExtension, there’s nothing more to do. Be sure to include a copy of your federal extension (IRS 7004) when you file your state tax return.

Filing an New Jersey tax extension will not provide you with additional time to pay any tax balance due, which must be paid by your original filing deadline or interest and other payment penalties may apply.
