Respond via the Employer Response Portal within 7 days of separation. Failure to respond carries a penalty of $500 or 25% of benefits paid, whichever is greater. Appeals must be filed within 10 calendar days.
NJ Payroll Tax Guide 2026
Every NJ employer payroll tax in one place: SUI, SDI, FLI, WF/SWF rates and wage bases, NJ-927 filing deadlines, NJ-W-3 reconciliation, and the penalties you need to avoid. Updated for 2026 by Greg Monaco, CPA.
How NJ's Payroll System Works
New Jersey splits employer payroll compliance across two state agencies, which is why the system feels more complex than most other states:
Division of Taxation
Administers NJ Gross Income Tax (GIT) withholding on wages and year-end filings (NJ-W-3, W-2). Withholding is a trust obligation — failure can create personal liability for business owners.
Department of Labor
Administers unemployment-related and leave-related contributions (UI, TDI/SDI, FLI, WF/SWF) and quarterly wage reporting (WR-30). Separate portal, separate penalties, separate rules.
2026 NJ Payroll Tax Rates & Wage Bases
Every NJ payroll tax component with current rates, wage bases, and who pays. Your payroll system needs at least two NJ wage-base accumulators.
| Tax | Who Pays | 2026 Rate | Wage Base | Max Per Employee |
|---|---|---|---|---|
| UI (Employer) | Employer | 0.5% – 5.8%* | $44,800 | $224 – $2,598 |
| WF/SWF (Employer) | Employer | 0.1175%** | $44,800 | $52.64 |
| TDI (Employer) | Employer | 0.10% – 0.75% | $44,800 | $44.80 – $336.00 |
| UI (Employee) | Employee | 0.3825% | $44,800 | $171.36 |
| WF/SWF (Employee) | Employee | 0.0425% | $44,800 | $19.04 |
| TDI (Employee) | Employee | 0.19% | $171,100 | $325.09 |
| FLI (Employee) | Employee | 0.23% | $171,100 | $393.53 |
| NJ GIT (Employee) | Employee | 1.4% – 10.75% | No cap | Varies |
* Experience-rated under Table C (FY July 2025 – June 2026). New employer total rate: 2.8% (includes WF/SWF).
** WF/SWF is embedded within the employer UI rate tables — it is carved out, not added on top.
Employee rows highlighted. Total max NJ employee deductions for 2026: $909.02 (before GIT).
Example: Cost Per Employee
New Employer, One Employee Earning $65,000/Year
A new NJ employer hires their first employee at $65,000. Here are the NJ-specific employer costs (federal FICA/FUTA are separate):
| Tax | Calculation | Annual Cost |
|---|---|---|
| Employer UI/WF/SWF (2.8%) | $44,800 x 2.80% | $1,254.40 |
| Employer TDI (0.50%) | $44,800 x 0.50% | $224.00 |
| Total NJ Employer Cost | $1,478.40 |
The employer also withholds $909.02 from the employee's paychecks across UI/WF/SWF ($190.40), TDI ($325.09), and FLI ($393.53), plus NJ income tax based on the employee's NJ-W4. Note: only the first $44,800 in wages is subject to employer taxes — wages above that threshold carry no additional NJ employer cost.
NJ SUI Experience Rating Explained
Your SUI rate is not fixed. NJ uses a reserve ratio method where two factors determine your rate: the statewide Trust Fund condition and your individual claims history.
The Column System
The Trust Fund Reserve Ratio determines which rate table (Column A through E+10%) applies statewide. Table C is in effect for FY 2025–2026, down from Table D the prior year — saving NJ employers an estimated $300 million annually.
| Column | Rate Range |
|---|---|
| A (Best) | Lowest rates |
| B | Low-moderate |
| C (Current) | 0.5% – 5.8% |
| D (Prior Year) | 0.6% – 6.4% |
| E | 1.2% – 7.0% |
| E+10% (Worst) | E rates + 10% |
Your Individual Rate
Within the statewide column, your employer-specific reserve ratio determines your exact rate. Your reserve balance = cumulative UI contributions paid minus cumulative benefits charged. That balance divided by your average annual taxable payroll produces your reserve ratio.
Under Table C, there are 28 rate categories: 18 for positive reserve ratios (0.5% to 3.6%) and 10 for negative/deficit ratios (5.1% to 5.8%). The better your claims history, the lower your rate.
Managing Your SUI Rate
Make Voluntary Contributions
File Form UC-45 within 30 days of your annual rate notice to buy down your reserve ratio. Compare the contribution cost against the tax savings — especially valuable when you're near a rate tier boundary.
Document Separations
Maintain written warnings, performance reviews, policy acknowledgments, and exit records. Review Form B-187Q (quarterly benefits-charged statement) to catch incorrect charges before they affect your rate.
Example: Experience Rating Impact
10-Employee Company, Year 4 (First Experience-Rated Year)
After three years at the 2.8% new employer rate, this company's experience rating kicks in. The difference between a clean claims history and a poor one is dramatic:
| Scenario | UI Rate | Per Employee | 10-Employee Cost |
|---|---|---|---|
| Best rate (strong reserve) | 0.5% | $224 | $2,240 |
| Mid-range rate | 3.0% | $1,344 | $13,440 |
| Worst rate (deficit reserve) | 5.8% | $2,598 | $25,984 |
The spread is $23,744 per year for just 10 employees. Contesting improper unemployment claims, documenting separations properly, and considering voluntary contributions can save thousands.
TDI & FLI: What Employers Must Know
NJ's Temporary Disability Insurance and Family Leave Insurance programs create obligations for every NJ employer — even when the employee pays 100% of the tax.
Temporary Disability Insurance (TDI)
- •Covers employee's own non-work-related illness, injury, or pregnancy
- •Up to 26 weeks of benefits, 7-day waiting period
- •85% of average weekly wages, capped at $1,119/week (2026)
- •Funded by both employer (0.10%–0.75%) and employee (0.19%)
- •New employer TDI rate: 0.50% for FY 2025–2026
- •Private plan option available with Division approval
Family Leave Insurance (FLI)
- •Covers bonding with new child, caring for ill family member, or domestic violence
- •Up to 12 weeks continuous or 56 intermittent days
- •85% of average weekly wages, capped at $1,119/week (2026)
- •Funded 100% by employee — employers contribute nothing
- •Employee rate: 0.23% on first $171,100 (max $393.53)
- •Expanded "family member" definition includes chosen family
Filing Deadlines & Forms

W-2 Reporting for NJ Payroll Taxes
Employee NJ payroll contributions must be reported in Box 14 of Form W-2 using standard labels. Getting this right matters — employees use these amounts for NJ tax credits on Form NJ-2450.
| W-2 Box | Content | Common Label |
|---|---|---|
| Box 14 | UI/WF/SWF employee contributions | UI/WF/SWF or UI/HC/WD |
| Box 14 | TDI employee contribution | SDI or DI or TDI |
| Box 14 | FLI employee contribution | FLI |
| Box 15 | Employer NJ State ID number | NJ Tax ID (12-digit) |
| Box 16 | NJ state wages | May differ from Box 1* |
| Box 17 | NJ state income tax withheld | NJ SIT |
* NJ does not allow pre-tax 401(k) deductions when computing state taxable wages, so Box 16 (NJ wages) may be higher than Box 1 (federal wages). Some payroll providers mistakenly report FLI in Box 17 — employees should not add FLI to their NJ income tax withholding totals.
Example: Federal vs. NJ Payroll Tax Stack
Total Employer Cost, Employee Earning $100,000
Here is the full payroll tax picture for one employee at $100,000/year with a new employer:
| Tax | Taxable Wages | Rate | Amount |
|---|---|---|---|
| Federal | |||
| Social Security (OASDI) | $100,000 | 6.20% | $6,200 |
| Medicare (HI) | $100,000 | 1.45% | $1,450 |
| FUTA | $7,000 | 0.60% | $42 |
| NJ State | |||
| NJ UI/WF/SWF (Employer) | $44,800 | 2.80% | $1,254 |
| NJ TDI (Employer) | $44,800 | 0.50% | $224 |
| Total Employer Cost | $9,170 | ||
NJ employer-side payroll taxes add $1,478 on top of the $7,692 in federal employer taxes — a 19% increase in total employer payroll tax burden. As your SUI rate drops through experience rating, this NJ cost decreases significantly.
Special Situations
NJ payroll rules vary for certain employer and employee types.
S-Corp Owner-Employees
S-Corp shareholders who perform services must receive W-2 wages subject to all federal and NJ payroll taxes. The IRS requires 'reasonable compensation' before distributions — zero salary is a guaranteed audit trigger. NJ S-Corps also need Form CBT-2553 for the separate state S election.
Household / Domestic Employers
If you pay $1,000+ in cash wages per calendar quarter to household employees, you must register via NJ-REG and file Form NJ-927-H annually by January 31. No quarterly NJ-927 filing is required unless you also have regular employees.
Tipped Employees
NJ's 2026 tipped cash wage is $6.05/hour with a max tip credit of $9.87 against the $15.92 minimum wage. If cash wages plus tips fall below minimum wage, the employer makes up the difference. Overtime is calculated on the full minimum wage.
NJ/PA Reciprocal Agreement
PA residents working in NJ may file Form NJ-165 to exempt themselves from NJ income tax withholding. This covers wages, salaries, tips, and commissions only — not self-employment income. NJ SDI, SUI, FLI, and WF contributions still apply. NJ residents working in PA file REV-419 for the reverse exemption.
NY/CT Nonresidents & Convenience Rule
No reciprocal agreement exists with NY or CT. NJ employers must withhold NJ GIT from NY/CT residents working in NJ. Under the Convenience of the Employer rule (P.L. 2023, c.125, retroactive to January 1, 2023), wages of NY, DE, and NE residents telecommuting for NJ employers are allocated to NJ unless by employer necessity.
Agricultural Employees
Agricultural employees follow a separate, lower minimum wage schedule: $14.20/hour (2026), converging with the standard rate by 2030. Agricultural employers may be exempt from NJ SUI in certain circumstances. NJDOL outlines specific agricultural coverage thresholds.
10 Costly NJ Payroll Mistakes
Setting up only federal payroll and NJ income tax withholding
Many small businesses miss the five additional NJ-specific taxes (UI, TDI, FLI, WF, SWF). Failing to withhold SDI and FLI from employee paychecks leaves the employer liable for the amounts that should have been deducted.
Using the wrong SUI rate after the new-employer period
New employers get a flat 2.8% rate for three years, then transition to experience-rated. Verify your rate on the annual Notice of Employer Contribution Rate and consider voluntary contributions (Form UC-45) when near a rate tier boundary.
Missing WR-30 filings
The individual employee wage detail report is required every quarter, even when no wages are paid. Escalating per-employee penalties ($5/$10/$25) accumulate quickly for larger employers who repeatedly miss filings.
Not reconciling NJ-927 totals to the annual NJ-W-3
Discrepancies between quarterly NJ-927 totals and the annual reconciliation (due February 15) trigger notices and potential audit selection. This is one of the most common missed-deadline issues.
Setting S-Corp owner salary artificially low
The IRS requires 'reasonable compensation' — courts have reclassified distributions as wages when salaries are artificially low. This cascades into NJ payroll compliance and creates exposure on both federal and state levels.
Misclassifying employees as independent contractors
NJ uses the ABC test — one of the strictest nationally. The burden falls entirely on the employer. Under the NJ Wage Theft Act, violations carry treble damages (3x unpaid wages) and penalties of up to 5% of the worker's gross earnings.
Not responding to unemployment claims within 7 days
Under P.L. 2022, c.120, employers must submit separation information within 7 days of separation or notice of a claim via the Employer Response Portal. Failure carries a penalty of $500 or 25% of benefits paid, whichever is greater, and you may lose appeal rights.
Missing registration deadlines
You must file NJ-REG when paying $1,000+ in covered NJ wages and report new hires to the NJ New Hire Reporting Center within 20 days. Late registration cascades into inability to file returns and mounting penalties. Withholding must begin with the very first paycheck — there is no grace period.
Not applying the NJ/PA reciprocal agreement
PA residents working in NJ should file Form NJ-165 (Certificate of Non-Residence) to exempt themselves from NJ income tax withholding. Failing to collect NJ-165 results in over-withholding and employee complaints. The reciprocal agreement covers compensation only — NJ SDI, SUI, FLI, and WF contributions still apply.
Not withholding NJ tax from NY residents under the Convenience rule
P.L. 2023, c.125 (retroactive to January 1, 2023) allocates wages of NY, DE, and NE residents telecommuting for NJ employers back to NJ unless remote work is by employer necessity. This is a compliance trap for employers with remote workers — failing to withhold creates underpayment exposure.
Penalty & Interest Reference
NJ payroll penalties are assessed by two different agencies with different rate structures.
Division of Taxation (GIT Withholding)
- •Late filing: 5% per month (max 25%) + $100/month
- •Late payment: 5% flat
- •Interest: Prime + 3% = 10.00% for 2026
- •E-file failure: $50 per return
- •Collection referral: 11% of total debt
Dept. of Labor (UI/TDI Contributions)
- •Failure to file quarterly report: $10 per day until filed
- •Late payment: 10% of delinquent contributions
- •Interest: 3% above prime rate from due date
- •WR-30 penalties: $5 (1st), $10 (2nd), $25 (3rd+) per employee
- •Failure to respond to claims: $500 or 25% of benefits
- •Misclassification: treble damages + 5% of gross earnings
New Employer Registration & Setup
New employers register using Form NJ-REG (Business Registration Application) filed with the Division of Revenue and Enterprise Services. This single form covers income tax withholding, UI, TDI, FLI, and sales tax. For corporations, LLCs, LLPs, and LPs, a Certificate of Formation must be filed first ($125 for-profit / $75 nonprofit).
Registration is triggered when you pay $1,000 or more in covered NJ employment during the calendar year, meet FUTA coverage requirements (20 weeks of employment or $1,500 quarterly payroll), or pay $1,000+ in quarterly cash wages to domestic workers. Upon registration, you receive a 12-digit NJ Taxpayer ID (FEIN plus 3-digit suffix) and a 4-digit PIN for online portal access. The same NJ Tax ID serves for both withholding and unemployment — there is no separate account number.
NJ Gross Income Tax Withholding
NJ uses its own Form NJ-W4 — employers cannot translate federal W-4 elections into NJ withholding. The NJ-WT publication contains the withholding tables (Rate Table A for Single/Married Filing Separately, Rate Table B for Joint/Head of Household) with wage chart letters A through S.
The withholding allowance value is $1,000/year ($19.20/week, $38.40 biweekly, $83.30 monthly). A key difference from federal withholding: NJ does not allow pre-tax 401(k) deductions when computing state taxable wages, so W-2 Box 16 (NJ state wages) may be higher than Box 1 (federal wages). If an employee does not submit an NJ-W4, default to the marital status and exemptions from the federal W-4. Employees expecting zero NJ liability may claim exempt on NJ-W4 line 6.
Supplemental wage handling: If supplemental wages (bonuses, commissions, overtime, tips) are paid with regular wages, withhold on the combined amount. If paid separately, withhold without NJ-W4 exemption allowances. Tips, commissions, and bonuses are all subject to NJ withholding.
NJ employers must withhold from: all NJ resident employees (with a limited exception for those already taxed by another state at a higher rate), nonresident employees working in NJ, and certain telecommuters under the Convenience of the Employer rule (P.L. 2023, c.125). PA residents may file Form NJ-165 for exemption under the reciprocal agreement.
The NJ ABC Test: Worker Classification
NJ uses the ABC test — one of the nation's strictest classification standards. A worker is presumed an employee unless the employer proves all three prongs:
A
Free from Control
The worker is free from direction over how work is performed, both contractually and in practice. Reserving the right to direct counts as control.
B
Outside Usual Course
The work is performed outside the employer's core business operations or outside all of the employer's places of business.
C
Independently Established
The worker is customarily engaged in an independently established trade. Merely forming an LLC or obtaining insurance at the employer's request does not satisfy this prong.
Failure on any single prong means the worker is an employee. The burden falls entirely on the employer. Under the NJ Wage Theft Act (2019), violations carry treble damages (3× unpaid wages), a 6-year statute of limitations, penalties of up to 5% of the worker's gross earnings over 12 months per violation, plus potential criminal exposure. April 2025 proposed rulemaking further tightened interpretive guidance. Governor Murphy's Task Force on Employee Misclassification has recovered $37 million for nearly 8,500 workers in 2024–2025 and issued 210 stop-work orders since 2019.
Trust Fund Liability & Personal Exposure
NJ Gross Income Tax withheld from employees is a trust fund held for the State. Under NJ law, any officer, director, or employee with a duty to collect and remit these taxes may be held personally liable for the full unpaid amount plus penalties and interest — regardless of whether the business entity can pay.
The NJ Tax Court's Cooperstein decision established a nine-factor test: corporate bylaws, officer status, check-signing authority, hiring/firing power, tax return responsibility, day-to-day involvement, creditor payment control, knowledge of non-remittance, and derivation of income from the entity. This mirrors the federal Trust Fund Recovery Penalty under IRC §6672 (100% penalty on responsible persons who willfully fail to remit).
Multi-State Payroll: NY, PA & CT
NJ employers with workers crossing state lines face distinct withholding and SUI rules for each state.
New York
No reciprocal agreement. NJ employers must withhold NJ GIT from NY residents working in NJ. Under the Convenience of the Employer rule (P.L. 2023, c.125, retroactive to January 1, 2023), wages of NY residents telecommuting for NJ employers are allocated to NJ unless remote work is by employer necessity. Employers splitting time between states must track and allocate workdays. NJ allocation formula: days worked in NJ ÷ total days × total wages.
Pennsylvania
Reciprocal agreement — PA residents working in NJ may file Form NJ-165 to exempt themselves from NJ income tax withholding. The agreement covers compensation only (wages, salaries, tips, commissions) — not self-employment or investment income. NJ SDI, SUI, FLI, and WF contributions are not covered by the reciprocal agreement and still apply. NJ residents working in PA file Pennsylvania Form REV-419.
Connecticut
No reciprocal agreement. Similar to NY, NJ employers must withhold NJ GIT from CT residents working in NJ. Employees file NJ nonresident returns and claim credits on their CT resident returns.
SUI for multi-state workers: SUI is reported to the state where services are localized (majority of work). When not localized, the hierarchy is: base of operations → state of direction and control → employee's state of residence. Employers cannot split SUI between states — determine the single proper state for each worker.
NJ Payroll Audits: Triggers & Defense
Approximately 1% of NJ employers are selected annually through random federal Tax Performance System audits. Beyond random selection, the most common trigger is a worker misclassification complaint — typically when a worker classified as a 1099 independent contractor files for unemployment benefits and no employer UI record exists.
Other triggers include temporary disability claims, wage complaints, inconsistencies in 1099 filings cross-referenced against SUI records, quarterly report delinquencies, and referrals from the Division of Wage and Hour or federal agencies. Auditors focus on payments to individuals not on the payroll and will determine whether those individuals should have been treated as employees under the ABC test.
Governor Murphy's Task Force on Employee Misclassification has intensified proactive enforcement, recovering $37 million for nearly 8,500 workers in 2024–2025 and issuing 210 stop-work orders since 2019. Maintaining proper documentation of all worker relationships — including written subcontractor agreements, proof of independent business operations, and consistent payroll records for all employees — is the strongest defense.
NJ SUI Wage Base: Historical Trend
NJ's UI taxable wage base has climbed steadily over the past decade, outpacing most states:
| Year | NJ UI Wage Base |
|---|---|
| 2021 | $36,200 |
| 2022 | $39,800 |
| 2023 | $41,100 |
| 2024 | $42,300 |
| 2025 | $43,300 |
| 2026 | $44,800 |
NJ's wage base is among the highest nationally — compared to California's $7,000, New York's $12,800, and the federal FUTA base of $7,000. Only Washington ($72,800) and a few others exceed NJ. NJ is also one of only three states (with Alaska and Pennsylvania) requiring employee UI contributions.

NJ Payroll Tax FAQ
What payroll taxes do NJ employers pay?
NJ employers pay Unemployment Insurance (UI), Temporary Disability Insurance (TDI), and Workforce Development/Supplemental Workforce Fund (WF/SWF) contributions on wages up to $44,800 (2026). Employers also withhold and remit employee-side UI/WF/SWF, TDI, Family Leave Insurance (FLI), and NJ Gross Income Tax. In total, there are five employer-paid and three employee-funded NJ payroll taxes beyond federal obligations.
What is the NJ SUI rate for new employers in 2026?
New employers in New Jersey receive a flat combined rate of 2.8% (2.6825% UI + 0.1175% WF/SWF) on the first $44,800 per employee for the first three calendar years. The new employer TDI rate is 0.50%. After three years, your rate becomes experience-rated based on your unemployment claims history.
What is the NJ payroll tax wage base for 2026?
NJ uses two wage bases in 2026: $44,800 for employer UI, TDI, and WF/SWF contributions (and employee UI/WF/SWF), and $171,100 for employee TDI and FLI contributions. You need both accumulators in your payroll system.
When is the NJ-927 due?
The NJ-927 (Employer's Quarterly Report) is due on the 30th of the month following each quarter: April 30, July 30, October 30, and January 30. Unlike federal Form 941, which is due on the last day of the month, NJ uses the 30th. The WR-30 (individual employee wage detail) shares these same deadlines.
What is the difference between NJ TDI and FLI?
TDI (Temporary Disability Insurance) covers an employee's own non-work-related illness, injury, or pregnancy — providing up to 26 weeks of benefits. FLI (Family Leave Insurance) covers bonding with a new child or caring for a seriously ill family member — up to 12 weeks. TDI is funded by both employer and employee; FLI is funded entirely by employee contributions. Both provide 85% of average weekly wages, capped at $1,119/week for 2026.
Do I need to withhold NJ taxes from employees who live in Pennsylvania?
For NJ Gross Income Tax: no, if the PA resident provides Form NJ-165 (Certificate of Non-Residence). The NJ/PA reciprocal agreement covers wages, salaries, tips, and commissions. However, NJ SDI, SUI, FLI, and WF contributions are NOT covered by the reciprocal agreement — PA residents working in NJ still pay these NJ payroll taxes.
What NJ payroll records must I keep and for how long?
NJ requires employers to maintain payroll records for at least 6 years under the NJ Wage and Hour Law. Records should include hours worked, wages paid, deductions withheld (NJ SUI, SDI, FLI, WF/SWF, GIT), dates of employment, and copies of all NJ-W4 forms, NJ-927 filings, and WR-30 reports.
How do I register as a new employer in New Jersey?
File Form NJ-REG (Business Registration Application) with the Division of Revenue and Enterprise Services. This single form covers income tax withholding, UI, TDI, FLI, and sales tax. You'll receive a 12-digit NJ Taxpayer ID Number and a 4-digit PIN for online portal access. Registration is required when you pay $1,000 or more in covered NJ employment during the calendar year.
What are the penalties for late NJ payroll tax filings?
For GIT withholding (Division of Taxation): 5% per month late filing penalty (up to 25%) plus $100/month, a flat 5% late payment penalty, and interest at prime + 3% (10.00% for 2026). For NJDOL contributions (UI/TDI): failure to file quarterly report on time carries a $10 per day penalty until filed; late payment penalty is 10% of delinquent contributions; interest runs at 3% above the prime rate from the due date. WR-30 penalties escalate per employee: $5 first failure, $10 second, $25 for third and subsequent within an 8-quarter window.
What is the NJ ABC test for worker classification?
NJ uses the ABC test — one of the nation's strictest classification standards. A worker is presumed an employee unless the employer proves ALL three prongs: (A) the worker is free from control and direction, both contractually and in practice; (B) the work is performed outside the employer's usual course of business or places of business; (C) the worker is customarily engaged in an independently established trade. Failure on any single prong means the worker is an employee. Merely forming an LLC or obtaining insurance at the employer's request does not satisfy Prong C. Under the NJ Wage Theft Act (2019), violations carry treble damages (3x unpaid wages), a 6-year statute of limitations, and penalties of up to 5% of the worker's gross earnings.
Are NY residents working in NJ subject to NJ payroll taxes?
Yes. There is no reciprocal agreement between NJ and NY. NJ employers must withhold NJ Gross Income Tax from NY residents working in NJ. Under NJ's Convenience of the Employer rule (P.L. 2023, c.125, retroactive to January 1, 2023), wages of NY, Delaware, and Nebraska residents telecommuting for NJ employers are allocated back to NJ unless the remote work is by employer necessity rather than employee convenience. NY residents file NJ nonresident returns and claim credits on their NY resident returns.
What triggers an NJ payroll tax audit?
Approximately 1% of NJ employers are selected annually through random federal Tax Performance System audits. The most common non-random trigger is a worker misclassification complaint — typically when a 1099 worker files for unemployment and no employer UI record exists. Other triggers include TDI claims, wage complaints, inconsistencies in 1099 filings cross-referenced against SUI records, report delinquencies, and referrals from the Division of Wage and Hour. Governor Murphy's Task Force on Employee Misclassification has recovered $37 million for nearly 8,500 workers in 2024–2025 and issued 210 stop-work orders since 2019.
What is the NJ Trust Fund Recovery Penalty?
NJ Gross Income Tax withheld from employees is a trust fund held for the State. Any officer, director, or employee with a duty to collect and remit these taxes may be held personally liable for the full unpaid amount plus penalties and interest. The NJ Tax Court's Cooperstein decision established a nine-factor test analyzing corporate bylaws, officer status, check-signing authority, hiring/firing power, tax return responsibility, day-to-day involvement, creditor payment control, knowledge of non-remittance, and income derivation. This mirrors the federal TFRP under IRC §6672. Trust fund liability is not dischargeable in bankruptcy.
Can I opt out of the NJ state disability plan?
Yes. Employers may substitute an approved private plan for TDI and/or FLI. Options include fully insured through an approved carrier, self-insured, or through a union welfare fund. Private plans must provide benefits at least equal to the state plan, with eligibility no more restrictive and employee contributions no greater. A majority employee vote is required if employees contribute. Plans must be approved by the Division's Private Plan Compliance Section before taking effect. While a private plan is active, neither the employer nor employees contribute to the State TDI Trust Fund. Advantages include potential elimination of the 7-day waiting period, faster claims processing, and integration with existing STD/LTD policies.
