NJ Form 1065: Complete Instructions for Partnerships Filing New Jersey partnerships and LLCs taxed as partnerships often assume income that passes through to partners means no state filing. That assumption causes trouble. A partnership with New Jersey-source income, or even one New Jersey-resident partner, can owe a return, a fee, or both.

This guide covers whether your entity must file, what NJ-1065 reports, which attachments apply, and when returns and payments are due. It follows the 2025 instructions, the latest year the Division of Taxation lists for partnerships. Check the current-year instructions before you file, because fees, deadlines, and attachments change.

Key Takeaways

  • Filing depends on New Jersey-source income, loss, or resident partners, not on whether the entity pays tax.
  • Federal Form 1065 is your starting point; New Jersey adjustments and NJK-1s still apply.
  • NJ-1065 and NJ-CBT-1065 are separate returns with separate purposes.
  • Extensions move the filing date, not the payment date.

Understanding NJ Form 1065 and Who Must File

What the Form Reports

NJ-1065 is not only an information return. Per the 2025 NJ-1065 instructions, it reports New Jersey-adjusted partnership income, New Jersey-source amounts, each partner's share, and the applicable filing fee under the Gross Income Tax.

Partners use their Schedule K-1 (NJK-1 in New Jersey) to report their allocable share of income, deductions, and credits on their own returns.

Who Files

Any entity classified as a partnership for federal purposes may need to file, including qualifying LLCs and LLPs. The trigger is either:

  • New Jersey-source income or loss, or
  • Any type of New Jersey-resident partner.

An out-of-state principal business location does not remove the obligation. Qualifying investment clubs file too, but are exempt from the fee.

The fee and the filing duty are different tests. Having more than two owners is a fee condition, not the filing threshold. A partnership with no New Jersey-source income can be exempt from the fee yet still file because of a resident partner.

Federal, State and Partner Returns Compared

  • Federal Form 1065: reports total partnership results and supplies the starting figures.
  • NJ-1065: applies New Jersey adjustments, sources income, and calculates the fee.
  • Partner returns: each partner reports their NJK-1 share on their own New Jersey return.

Decision Checklist

  1. Is the entity classified as a partnership federally?
  2. Does it have New Jersey-source income or loss?
  3. Is any partner a New Jersey resident?
  4. Are there nonresident or foreign partners?
  5. What is the tax year (calendar, fiscal, or short)?
  6. Is this an initial, final, or amended return?

NJ-1065 vs NJ-CBT-1065

NJ-CBT-1065 is a separate Corporation Business Tax filing used when nonresident-partner tax must be calculated. The rate is 6.37% for noncorporate partners and 9% for corporate partners on applicable New Jersey-allocated income, subject to exemptions. Exempt partners provide an NJ-1065E, which the partnership keeps for audit.

Do not treat the two as interchangeable.

NJ Form 1065 Deadlines, Payments, and Extensions

Due Dates

  • Calendar 2025: April 15, 2026.
  • Fiscal year: the 15th day of the fourth month after year-end.
  • Short period: the federal Form 1065 due date.

If the last day falls on a weekend or New Jersey legal holiday, filing and payment are timely the next business day under N.J.A.C. 18:2-4.12.

Payments That May Apply

Obligation Rule
Filing fee Generally $150 per owner, capped at $250,000, with more than two owners and New Jersey-source income or loss
Advance fee installment Additional 50% of current-year fee, due at the original deadline; zero on a final return
Nonresident estimates Four 25% installments, paid electronically
BAIT Separate PTE-100 return; calendar 2025 due March 16, 2026
Composite NJ-1080-C Qualified nonresident individuals; calendar 2025 due April 15, 2026

BAIT is an annual electronic election made before payments and before the PTE-100, by its original deadline. It needs at least one individual, estate, or trust member liable under the Gross Income Tax.

Use voucher NJ-1065-V for the fee, but never mail it with the NJ-1065.

Extensions

NJ-1065 and NJ-CBT-1065 each receive a five-month extension. To qualify, make the required payments by the original due date:

  • NJ-1065: at least 80% of the fee plus installment, with PART-200-T.
  • NJ-CBT-1065: at least 90% of tax, with CBT-206.
  • PTE-100: six months, with the election deadline unchanged.

Do not attach the extension forms to the completed return. Keep the worksheets.

Electronic Filing

For 2025, CBT-subject partnerships using paid preparers must e-file, and any partnership with 10 or more partners must e-file regardless. The Division's online partnership service handles filing and payments.

Penalties and Interest

  • Late filing: 5% per month or part, up to 25% of outstanding tax, plus possibly $100 per month.
  • Late payment: 5% of the unpaid balance.
  • Missing e-file mandate: $100 per month or part.
  • Interest: prime plus 3 percentage points, compounded daily.

Penalties are charged on top of the tax itself. They do not replace it.

Annual Compliance Calendar

  • January to February: gather books, trial balance, and partner records.
  • February to March: reconcile federal results; decide on BAIT before its deadline.
  • March: file PTE-100 if electing; prepare NJK-1s.
  • By April 15: file NJ-1065 or extend, pay fee and installment, deliver NJK-1s.
  • After filing: save confirmations and copies.

Step-by-Step: How to Prepare NJ Form 1065

Gather Your Records

  • Partnership agreement and EIN
  • Accounting records and trial balance
  • Federal Form 1065
  • Partner ownership and address data
  • Prior-year state return
  • Details of New Jersey activity

Complete Entity Information

Enter these entity details on the return:

  • Legal and trade name, address, and FEIN
  • Business activity, start date, and fiscal year dates
  • Partner counts
  • Initial, Final, or Amended status
  • Extension or allocation boxes, if applicable

Reconcile Federal to New Jersey

Start with federal ordinary income plus separately stated interest, dividends, rents, and gains or losses. Then adjust for items such as:

  • Income-based taxes and guaranteed payments
  • Exempt-obligation income
  • Section 179 and depreciation (use GIT-DEP where applicable)
  • Tiered-partnership items

Source the Income

Operational income uses market-based sourcing with a single sales factor, reported on NJ-NR-A or an approved substitute. Nonoperational and nonunitary items go through Schedules O and A.

Skipping the allocation schedule has a steep cost. Missing NJ-NR-A can lead to 100% New Jersey sourcing of partnership income or loss.

Partner Schedules

Prepare an NJK-1 for every partner who was a partner at any point in the year. Include address, federal ID, ownership share, income or loss share, and New Jersey-source amounts.

Pre-Submission Review

  1. Compare the state return with the federal return.
  2. Confirm every partner is listed with address and federal ID.
  3. Assemble the required attachments.
  4. Sign the return. An unsigned NJ-1065 is not a return.
  5. File through the approved channel and pay amounts due.
  6. Save proof of filing.

NJ Form 1065 Attachments and Partner Reporting

What Goes With the Return

Always attach:

  • An NJK-1 for every partner
  • Federal Form 1065 pages 1 to 5, Form 8825, and Schedule D
  • Filed federal extension requests, including Form 7004

Attach when applicable:

  • NJ-NR-A
  • Schedule A (tiered partnerships) and Schedule O (nonoperational activity)
  • GIT-DEP
  • Schedule B (Sheltered Workshop Tax Credit) and Schedule L (complete liquidation)
  • Lower-tier NJK-1s and PTE-K-1s received

Retain, Don't Attach

Keep copies of issued NJK-1s, the complete federal return and support, and any NJ-1065E. The 2025 instructions set no fixed retention period, so confirm the right timeframe with your adviser.

Partner Delivery

Key partner delivery rules:

  • Issue NJK-1s to partners by the NJ-1065 due date
  • Give BAIT members a separate PTE-K-1 by the PTE-100 due date
  • Do not treat the PTE-K-1 as a substitute for the NJK-1
  • Nonresidents attach the NJK-1 to claim tax paid on their behalf

Records Checklist

  • Books and workpapers
  • Capital and ownership records
  • Federal and state returns
  • Payment evidence and extension worksheets
  • Correspondence
  • Copies of partner statements

After Filing: Common Errors, Records, and When to Get Help

Common Mistakes

  • Confusing NJ-1065 with NJ-CBT-1065
  • Copying federal amounts without state adjustments
  • Omitting a partner schedule or the NJ-NR-A
  • Mailing NJ-1065-V with the return
  • Assuming an extension delays payment
  • Leaving preparer signature or tax-ID blank (possible $25 each)

Amended and Final Returns

To amend, use the applicable year's NJ-1065, mark Amended, explain the changes, and send corrected NJKs to the Division and affected partners. Amend within 30 days of an amended federal return, or 90 days after a final federal audit determination.

For a final return, mark Final and attach Schedule L for a complete liquidation. The final fee is still payable. For 2025, no separate superseding procedure applies, so use an amendment to correct a filed return.
