This guide covers returns filed in 2026 for tax year 2025. The final annual form for tax year 2026 won't be available until 2027, so every threshold, line number and rate below comes from the 2025 NJ-1040 package. It's written for full-year residents, part-year residents, nonresidents with New Jersey income, employees, freelancers and business owners.
Key Takeaways
- Download the current NJ-1040 and instructions from the Division of Taxation, not an old form or a third-party summary.
- New Jersey Gross Income (line 29) is not federal AGI, so don't copy federal figures across.
- An extension gives you more time to file, not more time to pay.
- Check residency, filing status, W-2 Box 16 wages, withholding and estimated payments before you submit.
NJ-1040 Basics and Who Needs to File
Which form you file depends on residency:
- NJ-1040 covers full-year and part-year residents
- NJ-1040NR is for nonresidents reporting New Jersey-source income
- Part-year residents may need both, one for the resident period and one for the nonresident period
2025 filing thresholds
According to the 2025 NJ-1040 instructions, you generally must file when your New Jersey gross income is more than:
| Filing status | Threshold |
|---|---|
| Single; married/civil union filing separately | $10,000 |
| Married/civil union jointly; head of household; qualifying widow(er)/surviving partner | $20,000 |
You may still want to file below the threshold. Doing so is how you recover withheld tax or claim refundable credits such as the NJ Earned Income Tax Credit.
Residency and filing status
Residency drives almost everything else on the return.
- Domicile is the permanent home you intend to return to. You can have only one at a time.
- A New Jersey-domiciled person can avoid resident treatment only if they have no permanent NJ home, keep a permanent home elsewhere, and spend no more than 30 days in New Jersey.
- Someone domiciled elsewhere is a resident if they keep a permanent NJ home and spend more than 183 days in New Jersey.
Filing status generally matches your federal status, and civil-union partners use the married/civil union statuses.
If one spouse is a full-year nonresident and the other is a resident for part of the year, the resident may file separately. Choosing a joint resident return puts both spouses' income under resident treatment.
Where to find the forms
The Division of Taxation's income tax forms page lists the NJ-1040, NJ-1040NR, instructions, schedules, tax tables and payment guidance in one place. Always use it as your starting point.
How to Complete Form NJ-1040 for 2025
Gather your documents
- W-2s and any 1099s showing New Jersey withholding
- 1099-INT, 1099-DIV and retirement distribution statements
- Business and rental records
- Property tax bills or rent receipts
- Last year's return
- Estimated payment confirmations, including any 2024 overpayment carried forward
Complete the top of the return
Enter your identifying details, residency period, filing status, spouse and dependents. Exemptions for 2025 are:
- $1,000 for you and for a qualifying spouse or partner
- $1,500 per qualifying dependent
- An extra $1,000 each for age 65+ and for blind or disabled

Report income
Here is the 2025 line map for the main income categories:
| Line | Item |
|---|---|
| 15 | Wages, salaries, tips (W-2 Box 16) |
| 16a / 16b | Taxable / tax-exempt interest |
| 17 | Dividends |
| 18 | Net business profits |
| 19 | Gains from disposition of property |
| 20a / 20b | Taxable / excludable pensions, annuities, IRAs |
| 21 / 22 | Partnership / S corporation income |
| 23 | Rents, royalties, patents, copyrights |
| 27 | Total income |
Use Box 16 state wages, not federal Box 1. They can differ, especially when you contribute to a 403(b) or 457 plan, since those contributions generally aren't excluded for New Jersey.
From total income to NJ Gross Income
Line 29 is line 27 minus line 28c, the pension and retirement exclusions. This is your New Jersey Gross Income. Match these line references to the form version you file, since numbering can shift between years.
Final review
Before you sign, confirm:
- Deductions and the property tax deduction or credit (lines 31–41)
- NJ withholding (line 55), property tax credit (56) and estimated payments (57)
- Credits such as NJEITC (58) and child and dependent care (64)
- Balance due or refund
Paper returns need original signatures, and both spouses sign a joint return. Enclose all W-2s, 1099s showing New Jersey withholding, and any applicable schedules (NJ-BUS-1, NJ-DOP, NJ-COJ, NJ-2210).
NJ Income, Deductions, Credits, and Tax Calculation
Federal AGI versus NJ Gross Income
New Jersey doesn't start from federal AGI. It taxes income by category, and a net loss in one category can't offset income in another. A business loss can't wipe out your wages, for example.
Federal deductions for tips, overtime and seniors under the One Big Beautiful Bill Act also don't change the New Jersey individual income tax. Other differences to watch:
- Pretax employee 401(k) contributions get exclusion treatment in New Jersey, but 403(b)/457 contributions generally don't.
- Municipal-bond interest from other states can be taxable in New Jersey despite being federally exempt.
- Taxable pension amounts can differ from federal ones because contribution basis differs.
- Social Security benefits are not taxable in New Jersey.
Retirement exclusions
Per the Division's retirement income guidance, you qualify if you're 62 or older (or disabled under Social Security rules) at year-end and line 27 total income is $150,000 or less. If only one spouse qualifies, only that spouse's pension counts.
| Total income | Joint | Single/HOH | Separate |
|---|---|---|---|
| $100,000 or less | Up to $100,000 | Up to $75,000 | Up to $50,000 |
| $100,001–$125,000 | 50% of taxable pension | 37.5% | 25% |
| $125,001–$150,000 | 25% | 18.75% | 12.5% |
The exclusion can't exceed your eligible pension income. A separate Other Retirement Income Exclusion exists, with its own worksheet.
Deductions and credits
- Medical: Unreimbursed expenses above 2% of NJ gross income.
- Education: NJBEST (up to $10,000), NJCLASS (up to $2,500 of principal and interest) and qualifying tuition (up to $10,000), if gross income is $200,000 or less.
- Property tax: Choose either a deduction of up to $15,000 or a $50 refundable credit, whichever helps more. Renters use 18% of qualifying rent. Vacation homes don't qualify.
- NJEITC: Generally 40% of the allowed federal EIC, claimable even below the filing threshold.
- Child and dependent care: Refundable for filers with NJ taxable income of $150,000 or less, at 10% to 50% of the federal credit.
- Other-jurisdiction credit: For income taxed by both New Jersey and another state. Enclose NJ-COJ.
Rates and tax tables
Under $100,000 of line 42 taxable income, use the tax table that starts on page 54 of the instructions. At $100,000 or more, use the rate schedules on page 63. Rates are marginal, so each band is taxed at its own rate. For single filers, the 2025 range runs from 1.4% on the first $20,000 up to 10.75% above $1 million.
Withholding and estimated payments
Withholding goes on line 55 and estimated payments on line 57. Compare them with your line 43 tax: more tax than payments means a balance due, and the reverse means a refund. You generally need estimated payments if you expect to owe more than $400 after withholding and credits. Freelancers without withholding are the usual case.
Deadlines, Extensions, and How to File
Deadlines
The 2025 return and payment are due Wednesday, April 15, 2026. Federal Form 1040 has the same date this year, but New Jersey sets its own rules, so confirm each separately.
An extension runs six months, to October 15, 2026. It only extends the time to file. You still owe at least 80% of your final liability by April 15.
A federal extension plus sufficient NJ payment usually means you don't need NJ-630. Use NJ-630 for a state-only extension or to send the payment.
Filing methods
- NJ Online Filing: Free for full-year and part-year residents filing NJ-1040.
- NJ E-File: Through approved software or a preparer.
- Paper: Slower and needs original signatures.
NJ Direct File was discontinued for 2025. Keep your confirmation number and a full copy of the return and enclosures.
Estimated payments and penalties
Estimated dates for 2026 are April 15, June 15, September 15, and January 15, 2027. To avoid an underpayment penalty, pay on time at least 80% of current-year liability or 100% of prior-year liability. NJ-2210 calculates the interest.
Penalty and interest rates:
- Late filing: 5% per month or part-month, capped at 25% of the tax due
- Extra late-filing amount: $100 per late month may also apply
- Late payment: can add 5%
- Interest: prime plus 3 percentage points
Refund timing
For returns filed after January 26, 2026, the state's refund status page cites these benchmarks:
| Situation | Timeframe |
|---|---|
| Electronic | 4 weeks or more |
| Mailed paper | At least 12 weeks |
| Extra processing or certified-mail paper | 15 weeks or more |
Special Situations and Common Filing Mistakes
Part-year residents and nonresidents
Your entire-year income determines whether you meet the filing threshold. Income earned during the resident period goes on NJ-1040, including out-of-state income.
The Division's own example: a single filer earned $23,000 while living elsewhere for 10 months, then $2,900 in two months in New Jersey. The $2,900 is taxable because total-year income exceeds $10,000.
Use the part-year worksheets rather than assuming every deduction prorates the same way.
On NJ-1040NR, column A shows worldwide income under NJ rules and column B shows NJ-source income during nonresident periods.
Freelancers, remote workers and multi-state earners
- Freelancers: Report business income with NJ-BUS-1. NJ-source self-employment income isn't covered by wage reciprocity.
- Pennsylvania residents: NJ wages are exempt under reciprocity, but other NJ-source income is taxable. Recover erroneous NJ wage withholding on NJ-1040NR.
- New York residents working for a NJ employer: File a full-year nonresident return, following the Division's example.
- Telework: New Jersey's convenience-of-employer rule applies to residents of states with a similar rule. Remote work for personal convenience can leave NJ-employer wages taxable.
- Multiple W-2s or 1099s: Don't enter duplicates.
Mistakes the state sees most
- Wrong Social Security number or filing status
- Federal wages entered instead of NJ Box 16 wages
- Duplicate W-2 entries or negative amounts in an income category
- Missing withholding forms
- Overstated NJ-COJ credit
- Counting Family Leave Insurance as income tax withholding
- Forgetting estimated payments or a prior-year carryforward
- Missing signatures
- Ignoring a notice
