2023 NJ-1040X Form Instructions

To submit the 2023 NJ-1040X form, mail the completed and signed form along with all required enclosures to: STATE OF NEW JERSEY, DIVISION OF TAXATION, REVENUE PROCESSING CENTER, PO Box 664, TRENTON NJ 08646-0664. Ensure you include copies of all supporting schedules and forms, such as W-2s and 1099s. My advice is to double-check all information and enclosures before submission to avoid delays or disallowed claims.

The important dates for the 2023 Form NJ-1040X include April 15, 2024, which is the deadline for filing the original tax return, and October 15, 2024, which is the extended deadline. For refunds, amended returns must be filed within three years of the original filing date or two years from when the tax was paid, whichever is later.

The purpose of the 2023 NJ-1040X form is to allow taxpayers to amend their previously filed New Jersey resident Income Tax returns. This may be necessary if errors were discovered after the original filing or if additional information needs to be provided. The form ensures that all corrections are documented and allows taxpayers to comply with state tax regulations.
