As long as you have filed a timely return with NJ, and requested that your payment be direct debited on or before the deadline, you should be fine. You'll have proof of your filing on the "Electronic Filing Instructions" page of your NJ PDF. And if, by chance, your NJ return is rejected (keep an eye on your email), you have until April 23 to correct and re-submit your return.
What if my return is still pending or rejected on April 18?
