5. Final Steps Before Filing

  • Double-check your math: Errors are the most common reason for refund delays.
  • Verify direct deposit info: One wrong digit sends your refund elsewhere.
  • Sign and date your return: Unsigned returns are rejected.
  • Keep copies: Retain a full copy of your return and supporting documents for at least 4 years.
  • Consider e-filing: Faster processing, fewer errors, and immediate confirmation.
  • Set a reminder for next year: Mark deadlines in your calendar now.

The Homestead Benefit is a credit for NJ homeowners meeting income limits. You must apply annually by November 1. It's not automatic.
