Introduction
The right address for a paper NJ-1040 depends on four things: the tax year, whether you owe a balance, the form you're filing, and how you're sending it. Get one wrong and your return can sit in the wrong processing queue.
New Jersey's refund wait shows why accuracy matters. The Division of Taxation lists 12+ weeks for mailed returns versus 4+ weeks for electronic ones, per its refund status page.
Addresses below follow the 2025 NJ-1040 instructions. Confirm them against the official Division of Taxation page before sealing the envelope.
This guide covers choosing the address, preparing the return, deadlines, special cases and common errors. If you're filing a New Jersey return from Australia, figures are in US dollars.
Key Takeaways
- Use the current Division of Taxation instructions for the address, never an old return or an IRS address.
- Refund or no-tax-due returns go to PO Box 555; balance-due returns go to PO Box 111.
- Confirm NJ-1040 is the right form: nonresidents use NJ-1040NR, amendments use NJ-1040X.
- Keep a full copy of the signed return, payment record and mailing proof.
What Mailing Address Applies to Your NJ-1040 Return?
Official Addresses for the Standard Resident Return
New Jersey routes paper returns by outcome: refund or no tax due, versus balance due. All addresses below are for the 2025 NJ-1040.
| Situation | Address |
|---|---|
| Refund or no tax due | State of New Jersey, Division of Taxation, Revenue Processing Center - Refunds, PO Box 555, Trenton, NJ 08647-0555 |
| Balance due | State of New Jersey, Division of Taxation, Revenue Processing Center - Payments, PO Box 111, Trenton, NJ 08645-0111 |
| Payment only, no return (for example after e-filing) | Revenue Processing Center - Payments, PO Box 643, Trenton, NJ 08646-0643, with a payment voucher |
| Private delivery, express or hand delivery | Revenue Processing Center, 200 Woolverton Street, Building 20, Trenton, NJ 08611 |
For a balance-due paper return, enclose the payment and Form NJ-1040-V together with the return. Don't send them separately.
Courier Versus USPS
PO Boxes can't receive FedEx or UPS deliveries. If you're mailing from Australia by courier, use the Woolverton Street address in the table. The IRS list of designated private delivery services applies to federal filings only and doesn't replace New Jersey's own courier address.
Verify Before You Mail
- Open the instructions for your specific tax year on the Division of Taxation site.
- Check the forms index for revised forms. The 2026 listing there is an estimated-payment voucher, not a resident return.
- Check the "Where to Mail Your Return" page for updates.
Don't Mix Up Addresses
Never send an NJ-1040 to the IRS. Other New Jersey forms also use different boxes:
- NJ-1040NR: PO Box 244, Trenton, NJ 08646-0244
- NJ-1040X: PO Box 664, Trenton, NJ 08646-0664
- NJ-1040-ES (estimated tax): PO Box 222, Trenton, NJ 08646-0222
Business returns such as the 2025 CBT-100 must be filed electronically and carry a "do not mail" notice.
How to Prepare and Mail an NJ-1040 Return
Gather Your Documents
- Completed NJ-1040 and NJ-HCC (health coverage) form
- All W-2s, plus 1099s showing New Jersey withholding
- Applicable schedules, such as federal Schedule B (if over $1,500), Schedule C, K-1s, NJ-COJ or NJ-2450
- Records supporting any deductions or credits
Assemble the Return
- Review every page for arithmetic and identification errors.
- Sign in blue or black ink. Photocopied signatures aren't accepted, and both spouses or partners sign a joint return. Improperly signed returns are sent back.
- Enclose supporting documents. The instructions say not to attach W-2s to the return itself, but to enclose them. Legible photocopies are accepted.
- Skip fasteners. No staples, paper clips or tape.
- One return per envelope. Use the envelope and address label in the booklet where provided.
New Jersey does not set a universal stacking order for schedules, so follow the form's own enclosure prompts.
Paying the Balance
Accepted methods are check or money order, e-check, or credit card. Make a mailed check payable to State of New Jersey - TGI. Write your Social Security number on it (for joint returns, both numbers in the order they appear on the return).
The 2025 NJ-1040-V also asks for the tax year. Include NJ-1040-V with mailed payments and leave it out when paying electronically.
Final Mailing Steps
- Print the destination and your return address clearly.
- Photocopy the entire signed package first.
- Send by a method that gives proof, such as certified mail or a tracked courier. From Australia, allow extra transit time.
Deadlines, E-Filing, and Proof of Delivery
Deadlines and Extensions
The 2025 calendar-year NJ-1040 and any payment were due April 15, 2026. An extension to October 15, 2026 is available if you've paid at least 80% of your New Jersey liability by April 15, per the Division's filing guidance.
An extension covers filing only, not payment. Missing the 80% threshold retroactively denies the extension, and penalties and interest run from the original due date.
Late filing carries 5% per month or part-month (maximum 25%), plus a possible $100 per late month. Late payment can add 5% of the outstanding balance.
Paper Versus E-File
| Method | Typical refund timing |
|---|---|
| Electronic | 4 weeks or more |
| Mailed | At least 12 weeks |
| Additional processing or certified-mail paper return | 15 weeks or more |
These aren't guaranteed dates. How you file also shapes processing. New Jersey's free online resident service requires a prior-year New Jersey return and can't amend a submitted return. Approved vendor software is the other route. E-filing still requires you to keep the complete return and records.
Proving You Filed on Time
Keep these records:
- Postmark or dated counter receipt
- Certified-mail receipt
- Delivery confirmation
- E-file acceptance
- Payment confirmation
- A full copy of the return
IRS Taxpayer Advocate guidance warns that postmarks can post-date mailbox deposit, so a dated counter receipt is safer than the postmark alone. Keep records until the limitation period ends, generally three years after filing or two years after payment, whichever is later.
Special Cases That May Require a Different Form or Process
Resident, Part-Year and Nonresident Filers
- Domicile: your permanent home, the place you intend to return to. You can have only one.
- Resident: generally anyone domiciled in New Jersey. The exception needs all three: no permanent New Jersey home, a permanent home elsewhere, and no more than 30 days in the state.
- Statutory resident: a non-domiciliary who keeps a permanent New Jersey home and spends more than 183 days there.
- Part-year resident: files NJ-1040 with residency dates. Income earned in New Jersey while a nonresident may also require NJ-1040NR.
- Nonresident: files NJ-1040NR, depending on New Jersey-source income and thresholds.
Confirm residency before choosing an address. Domicile continues through an absence, including time abroad, until you establish a new permanent home elsewhere.
Amending a New Jersey Return
Use NJ-1040X for the matching tax year and mail it to PO Box 664, Trenton, NJ 08646-0664. Include supporting schedules and forms, plus W-2 and 1099 copies showing New Jersey withholding even if unchanged. If the original was e-filed, include every schedule a paper original would require.
The refund window is generally three years from filing or two from payment, whichever is later. Confirm the exact deadline in the current New Jersey instructions, which may state the rule in slightly different terms. Changes made to your federal return that affect New Jersey tax also require a New Jersey amendment.
State Versus Federal Filings
Federal Form 1040 and 1040-X go to the IRS, not New Jersey. For a New Jersey resident, use these IRS addresses:
- No-payment Form 1040: Kansas City, MO 64999-0002
- Payment return: PO Box 931000, Louisville, KY 40293-1000
- Form 1040-X: Kansas City, MO 64999-0052, unless responding to an IRS notice
Residents abroad use different IRS addresses, so check the current IRS table.

- Mailing a balance-due return to the refund box, or the reverse
- Sending a courier package to a PO Box
- Using the NJ-1040 address for NJ-1040NR, NJ-1040X or estimated tax payments
Preparation Errors
New Jersey's common mistakes page lists issues that delay processing:

- Missing W-2 or 1099 copies showing New Jersey withholding

Check Before Sealing
Compare filing status, payment amount, balance due, direct-deposit details and attachments against the current instructions. Ten minutes here beats a 15-week reprocessing delay.
Final NJ-1040 Review: Key Next Steps

- Reconcile the return with W-2s, 1099s, withholding records, schedules and payments, and check every signature.
- Keep a submission file: signed return, mailing receipt or e-file acceptance, payment proof and later New Jersey correspondence.
