New Jersey state tax withholding is the state income tax your employer pulls from each paycheck and sends to the Division of Taxation as a prepayment against your annual NJ-1040 bill. How much comes out depends on three things: your filing status, the allowances you claim on Form NJ-W4, and which of the state’s graduated rate tables (A through E) applies to you. Get the form right and your withholding should track fairly closely to what you actually owe.
Who Has New Jersey Tax Withheld
Under N.J.S.A. 54A:7-1, any employer with an office or business activity in New Jersey must withhold state income tax from wages paid to both residents and nonresidents.1Justia Law. New Jersey Code 54A – Section 54A:7-1 If you live in New Jersey, your employer withholds on all wages regardless of where the work is performed. If you live elsewhere but earn from a New Jersey source, withholding applies to that income. Anything treated as wages for federal withholding is generally subject to New Jersey withholding as well.2New Jersey Department of the Treasury, Division of Taxation. New Jersey Gross Income Tax
Pennsylvania Residents Working in New Jersey
New Jersey and Pennsylvania have a reciprocal agreement, so wages a Pennsylvania resident earns from a New Jersey job are not subject to New Jersey income tax.3New Jersey Division of Taxation. PA/NJ Reciprocal Income Tax Agreement To stop the withholding, the employee has to file Form NJ-165 (Employee’s Certificate of Nonresidence in New Jersey) with the employer. Without that form, the employer withholds New Jersey tax by default and the worker has to file a nonresident return to recover it. The rule runs in the other direction too: New Jersey residents employed in Pennsylvania are exempt from Pennsylvania income tax on those wages.4NJ Division of Taxation.

Filling Out Form NJ-W4
Form NJ-W4 is the document you give your employer to set your withholding.5Division of Taxation. Employee’s Withholding Allowance Certificate (Form NJ-W4) Fill in your name, address, and Social Security number, then check one filing status:6New Jersey Division of Taxation. Employee’s Withholding Allowance Certificate
- Single
- Married/Civil Union Couple Joint
- Married/Civil Union Partner Separate
- Head of Household
- Qualifying Widow(er)/Surviving Civil Union Partner
Your filing status decides which withholding rate table your employer uses, so it drives the whole calculation. The form also includes a Wage Chart for people who hold multiple jobs or whose spouse also earns. Once combined household wages pass $50,000, the chart pushes withholding higher to keep you from owing at filing time.
Line 5 lets you ask for an additional flat dollar amount withheld from each paycheck, which is useful if you have side income, investment income, or a second job that isn’t fully covered by ordinary withholding. Claiming too many allowances does the opposite: less comes out per check, and you may owe tax plus an underpayment interest charge when you file.
Why New Jersey Has Its Own W-4
The state uses its own brackets, exemptions, and filing rules, so a federal W-4 alone won’t reflect your New Jersey situation. The statute does let employees claim the same number of exemptions they claim federally, and if no NJ-W4 is on file the employer can rely on the federal number.1Justia Law. New Jersey Code 54A – Section 54A:7-1 Filing a dedicated NJ-W4 still gives you more control, especially when your New Jersey taxable income differs from your federal adjusted gross income.
Claiming Exemption from Withholding
You can claim full exemption from New Jersey withholding if your total income for the year falls below one of these thresholds:6New Jersey Division of Taxation. Employee’s Withholding Allowance Certificate
- Single or Married/Civil Union Partner Filing Separately: wages plus taxable nonwage income of $10,000 or less.
- Married/Civil Union Couple Joint, Head of Household, or Qualifying Widow(er): wages (combined with a spouse’s, if any) plus taxable nonwage income of $20,000 or less.
The exemption is good for one year only. You have to submit a fresh NJ-W4 each year certifying that you still expect no New Jersey tax liability. If your income climbs above the threshold partway through the year, file an updated form so withholding restarts before a shortfall accumulates.
How Much Gets Withheld: The Rate Tables
Once your NJ-W4 is on file, your employer runs your wages through the Division of Taxation’s official rate tables.7State of New Jersey Department of the Treasury. Tables for Percentage Method of Withholding The tables are labeled Rate A through Rate E. Rate A generally applies to single filers and to married individuals filing separately. Rate B applies to head of household, qualifying surviving spouse, and married couples filing jointly.6New Jersey Division of Taxation. Employee’s Withholding Allowance Certificate
The system is progressive. For a single filer on the Rate A weekly table, the brackets run from 1.5% on the first $385 of taxable wages up to 11.8% on weekly taxable wages above $19,231.7State of New Jersey Department of the Treasury. Tables for Percentage Method of Withholding The full weekly Rate A schedule:
- $0 to $385: 1.5%
- $385 to $673: $5.77 plus 2.0% of the amount over $385
- $673 to $769: $11.54 plus 3.9% of the amount over $673
- $769 to $1,442: $15.29 plus 6.1% of the amount over $769
- $1,442 to $9,615: $56.35 plus 7.0% of the amount over $1,442
- $9,615 to $19,231: $628.46 plus 9.9% of the amount over $9,615
- Over $19,231: $1,580.38 plus 11.8% of the amount over $19,231
If the wrong table gets applied, or you picked the wrong filing status, the mismatch shows up at filing time as a large balance due or an oversized refund.
Non-Wage Income: Pensions, Gambling, and Contractor Payments
Standard wage withholding covers most workers, but a few other income types have their own rules worth knowing about.
Pensions and annuities. New Jersey withholding on pension and annuity payments is voluntary. If you want it, file Form NJ-W-4P with your payer and choose the dollar amount, with a minimum of $10 per payment.8State of New Jersey Department of the Treasury. Certificate of Voluntary Withholding of New Jersey Gross Income Tax from Pension and Annuity Payments If your total income for the year is $20,000 or less ($10,000 or less if single or married filing separately), you likely have no state liability and can skip it. Retirees without withholding often use quarterly estimated payments instead.
Gambling winnings. New Jersey requires 3% withholding on gambling winnings whenever the payer is also required to withhold federally.1Justia Law. New Jersey Code 54A – Section 54A:7-1 That covers casino winnings, sports betting payouts, and racetrack prizes for residents and nonresidents alike. State Lottery winnings follow a separate rate set by the Director of the Division of Taxation.9State of New Jersey. Lottery and Gambling Winnings
Unregistered construction contractors. If you hire an unregistered, unincorporated contractor for construction work on a property that is not your principal residence, you must withhold 7% of the payment.10New Jersey Department of the Treasury. Withholding Requirement for Construction Contractor Services You can skip the withholding if the contractor produces a valid Business Registration Certificate from the New Jersey Division of Revenue and Enterprise Services. Landlords and property investors miss this rule more often than any other.
Employer Remittance Deadlines
Employers send withheld tax to the Division of Taxation on a schedule tied to their prior-year withholding total.11NJ Division of Taxation. Reporting and Remitting
- Weekly payers: prior-year liability of $10,000 or more. Remit by the Wednesday after each payday and file Form NJ-927-W quarterly, due by the 30th of the month after the quarter closes.
- Monthly payers: employers below the weekly threshold who owe $500 or more in either of the first two months of a quarter. Remit on Form NJ-500 by the 15th of the following month.
- Quarterly payers: if the amount for either of the first two months is under $500, hold it and remit everything with the quarterly return on Form NJ-927, due by the 30th of the month after the quarter closes.
The third month of every quarter always goes in with the quarterly return, not separately. Employers keep NJ-W4 forms with their payroll records and produce them for the Division on request.5Division of Taxation. Employee’s Withholding Allowance Certificate (Form NJ-W4)
Avoiding an Underpayment Charge
If your withholding doesn’t cover enough of your annual tax, you can face an underpayment interest charge on the NJ-1040. The state calculates it on Form NJ-2210, but you don’t need to complete the form if the balance due is under $400.12New Jersey Division of Taxation. Underpayment of Estimated Tax by Individuals, Estates, or Trusts
You can generally avoid the charge if your total payments through withholding and estimated tax reach at least 80% of your current-year liability. Paying 100% of last year’s tax is another safe harbor, though it climbs to 110% if your prior-year gross income was over $150,000. If you have meaningful income outside your paycheck (rental income, freelance earnings, investment gains), pairing quarterly estimated payments with paycheck withholding is the cleanest way to stay covered.
When to Update Your NJ-W4
File a new NJ-W4 whenever a life event changes your tax picture: marriage, divorce, a new child, a spouse starting or stopping work, or taking on a second job. If the change reduces the allowances you’re entitled to, file the updated form quickly so your employer can adjust before a shortfall builds. The NJ-W4 goes to your employer’s payroll department only, not to the Division of Taxation.5Division of Taxation. Employee’s Withholding Allowance Certificate (Form NJ-W4) The current form is on the Division of Taxation’s website.
