New Jersey taxpayers can file their state income tax return electronically or by mail. The Division of Taxation encourages electronic filing, which generally allows returns and refunds to be processed faster.
Taxpayers who are owed a refund can choose direct deposit or receive a paper check, while those who owe taxes can submit payment when filing.
Refund processing times vary depending on how a return is filed and whether it requires additional review.
For returns filed after Jan. 26, 2026, the Division of Taxation says taxpayers should generally expect:
Four weeks or more for electronically filed returns
At least 12 weeks for mailed paper returns
15 weeks or more for returns requiring additional processing or paper returns sent by certified mail
Refunds that include a New Jersey Earned Income Tax Credit may take longer because those claims require additional review.
