Employer Payroll Tax Obligations in New Jersey

This section delves into the responsibilities of employers in New Jersey regarding payroll taxes, focusing primarily on the crucial aspect of withholding New Jersey Income Tax. Understanding and adhering to these obligations is paramount for businesses operating within the state to ensure compliance, avoid penalties, and support their employees in meeting their tax responsibilities.

The Employer as an Agent of the State

When an employer in New Jersey is mandated to withhold New Jersey Income Tax from their employees’ wages, they are essentially acting as an agent on behalf of the State of New Jersey. This means the employer bears the responsibility of correctly calculating, deducting, and remitting the appropriate tax amounts to the state government. This isn’t merely an administrative task; it’s a legal obligation with potential ramifications for non-compliance.

Consequences of Failing to Withhold

The failure to properly withhold New Jersey Income Tax can lead to significant negative consequences for employers:

Difficulty for Employees/Payees in Meeting Tax Obligations: When taxes aren’t withheld regularly, employees may face a substantial tax liability at the end of the tax year. This can create financial strain and negatively impact employee morale.
Potential Personal Liability for the Employer: In cases of negligence or intentional failure to withhold, the New Jersey Division of Taxation may hold the employer (or responsible individuals within the company) personally liable for the amounts that should have been withheld. This can result in direct financial penalties and legal action against the employer.

Defining the Employer-Employee Relationship for New Jersey Tax Purposes

New Jersey law aligns closely with federal tax regulations regarding the definition of an employee. If an individual is classified as an employee for federal income tax purposes, they are generally also considered an employee for New Jersey income tax purposes. This encompasses various forms of compensation, including:

Salaries
Wages (hourly pay)
Tips
Bonuses
Other forms of remuneration

Important Distinction: Benefits Subject to New Jersey Withholding but Not Federal

It’s crucial for New Jersey employers to be aware that there are certain employee benefits that might not be subject to federal income tax withholding but are subject to New Jersey income tax withholding. Employers must stay informed about these specific differences in state and federal regulations to ensure accurate withholding. Consulting the New Jersey Gross Income Tax Instructions for Employers (Form NJ-WT) is essential for identifying such benefits.

Who Must New Jersey Employers Withhold Income Tax From?

New Jersey employers are legally obligated to withhold New Jersey Income Tax from the following individuals:

All New Jersey Resident Employees: This applies to all employees whose primary residence is in New Jersey, regardless of where they physically work. However, an exception exists for residents who are already being taxed by another state at a rate equal to or higher than New Jersey’s rate. In such cases, withholding in New Jersey might not be required, but proper documentation may be necessary.
Nonresident Employees Working in New Jersey: Individuals who reside in another state but perform their work duties within the physical boundaries of New Jersey are subject to New Jersey income tax withholding.
Nonresident Employees Teleworking in New Jersey for Convenience: A significant point for the modern workforce, nonresident employees who telework from a location within New Jersey for their own convenience (and not due to employer requirement) are also subject to New Jersey income tax withholding. This clarifies the tax obligations for remote workers based in New Jersey.
Exception for Pennsylvania Residents Working in New Jersey: Due to a reciprocal agreement between New Jersey and Pennsylvania, Pennsylvania residents who work in New Jersey are generally exempt from New Jersey income tax withholding. However, these employees must complete and provide their employer with the Employee’s Certificate of Nonresidence in New Jersey to claim this exemption. Employers are responsible for ensuring this form is properly filled out and retained.
Unregistered Unincorporated Contractors: A distinct category, employers making payments to unregistered unincorporated contractors in New Jersey are required to withhold a flat 7% of the payment amount. This highlights the state’s focus on ensuring tax compliance even for independent contractors who haven’t formally registered their business structure.

Determining the Amount to Withhold

To accurately calculate the amount of New Jersey Income Tax to withhold from employee wages, employers must utilize the official resources provided by the New Jersey Division of Taxation. The primary resource for this is the New Jersey Gross Income Tax Instructions for Employers (Form NJ-WT). This document contains:

Tax Withholding Tables: These tables provide specific withholding amounts based on an employee’s filing status, withholding allowances claimed on their Form NJ-W4, and their wage level.
Alternative Calculation Methods: The instructions may also outline alternative methods for calculating withholding, which might be more suitable for certain payroll systems or complex situations.

Employers are responsible for obtaining the most current version of Form NJ-WT and adhering to the instructions and tables provided within it. Employees provide their withholding information via the Employee’s Withholding Allowance Certificate (Form NJ-W4). Employers must ensure they have a valid NJ-W4 on file for each employee subject to New Jersey withholding.

Electronic Filing Requirements for Year-End Forms

New Jersey requires employers to file all year-end payroll tax forms and statements electronically. This mandate covers various forms, including:

Form NJ-W-3: Reconciliation of Income Tax Withheld
Form W-2: Wage and Tax Statement
Form W-2G: Certain Gambling Winnings
Form 1099-MISC: Miscellaneous Income
Form 1099-R: Distributions From Pensions, Annuities, Retirement or Profit-Sharing Plans, IRAs, Insurance Contracts, etc.
Form 1094/1095 Series: Related to the Affordable Care Act (ACA)

It is the employer’s responsibility to ensure their payroll systems and procedures are capable of generating and submitting these forms electronically in the required format and by the established deadlines. Non-compliance with the electronic filing mandate or failure to meet the filing deadlines can lead to penalties imposed by the state.

Understanding Your Role as a New Jersey Employer for Payroll Tax

This section outlines key aspects of being an employer in New Jersey for payroll tax purposes, including determining employment status, obtaining necessary identification numbers, registering with the state, and understanding what types of compensation are subject to withholding.

Defining the Employer-Employee Relationship (Crucial Distinction from Unemployment Insurance)

It’s important to note that while the Division of Taxation handles income tax withholding, it does not determine the classification of workers as employees or independent contractors for the purpose of Unemployment Insurance. This determination falls under the purview of the New Jersey Department of Labor and Workforce Development (DOLWD).

The DOLWD utilizes the IRS ABC Test, as mandated by state law, to assess whether a worker should be classified as an employee or an independent contractor. New Jersey law presumes that workers are employees unless specific conditions are met. These conditions can include demonstrating that:

The worker is customarily engaged in an independently established trade, occupation, profession, or business.
The service performed by the worker is outside the usual course of the business for which such service is performed.
The worker is free from control or direction over the performance of their work, both under their contract of service and in fact.

DOLWD auditors and investigators use a Worker Classification Questionnaire to evaluate the nature of the relationship between a business and an individual providing services.

For questions regarding worker classification for Unemployment Insurance purposes, employers should:

Review the DOLWD’s Employment Under the NJ Unemployment Compensation Law informational packet.
Contact the DOLWD directly at (609) 292-2321.

How to Obtain a Federal Employer Identification Number (FEIN)

A Federal Employer Identification Number (FEIN) is a prerequisite for withholding New Jersey Income Tax. Employers can easily apply for a FEIN free of charge through the Internal Revenue Service (IRS) website. This unique nine-digit number identifies your business entity to the federal government.

How to Register as a New Jersey Employer for Withholding

To fulfill your New Jersey income tax withholding responsibilities, you must register as an employer with the state. This process can be completed online.

If your business is already registered in New Jersey but you are now hiring employees and need to inform the state of your employer status, you can also do so online.

Key Requirement: Federal Employer Identification Number (FEIN)

Regardless of whether you are a new business or an existing one becoming an employer, having a Federal Employer Identification Number (FEIN) is mandatory to register for New Jersey withholdings.

Additional Requirement for Corporate Entities: New Jersey Corporate Identification Number

If your business operates as a corporate entity, you will also need a 10-digit New Jersey Corporate Identification Number obtained from the Division of Revenue and Enterprise Services.

If you already possess a 10-digit ID number but cannot recall it, you have the following options:

Utilize the Business Name Search tool available on the Division of Revenue and Enterprise Services website.
Contact the Division of Revenue and Enterprise Services directly at (609) 292-9292.

Compensation Subject to New Jersey Income Tax Withholding

Generally, most compensation earned within New Jersey, whether by individuals who are residents of the state or nonresidents working within its borders, is subject to New Jersey income tax withholding. As a general rule, if an item is considered employee compensation for federal Income Tax withholding purposes, it is also subject to New Jersey Income Tax withholding.

The following items must be included when calculating the withholding amount for an employee’s compensation:

Salaries
Wages
Tips
Fees
Commissions
Bonuses
Other remuneration received for services rendered
Compensation paid under an accident or health insurance plan (Note the exception for temporary disability benefits mentioned below)
Employee contributions to retirement plans other than a 401(k) in the year they are made
401(k) contributions that exceed the federal limit
Amounts an employee takes out of cafeteria plans, even if the employee elects to receive benefits rather than cash
Combat zone compensation paid to members of the Armed Forces of the United States (for Tax Year 2020 and before), even if the income was excluded federally

Compensation Not Subject to New Jersey Income Tax Withholding

New Jersey specifically does not tax the following items, and they should not be included in the State wage portion of your employee’s Form W-2:

Temporary disability benefit payments required to be made under the State Plan administered by the Bureau of State Plan Disability Law.
Temporary disability benefit payments required to be made to employees under a company’s private plan.
401(k) contributions up to the federal limit.
Life insurance proceeds paid due to death.
Worker’s compensation due to personal injury or sickness.
Damages paid by suit or agreement due to personal injury, sickness, or wrongful imprisonment.
Scholarships paid by an educational institution.
Fellowship grants.
Amounts paid and used for travel, research, or equipment expenses incidental to a scholarship or research grant.
Commuter Transportation Benefits – up to a certain limit, provided the employee supplies proof of payment for alternative transportation (receipts, ticket stubs, etc.). Refer to the “Employee Tax Incentives for Employer-Provided Commuter Transportation Benefits” for detailed information.
Medical Savings Account (IRC Section 220, Archer MSA) contributions excludable for federal purposes.
Cafeteria plans that require a portion of the employee’s benefit dollars to be used to purchase certain benefits (commonly a minimum level of medical, life insurance, and/or long-term disability coverage).
Cafeteria plans when the employee receives cash instead of benefits if:
- The plan does not reduce an employee’s salary.
- The employee receives similar benefits from another source (e.g., a spouse’s/civil union partner’s coverage). Note that the value of the cash option is not taxable by the IRS in these specific circumstances.
Combat zone compensation paid to members of the Armed Forces of the United States (for Tax Year 2021 and after) that is excluded from federal taxable income.
Compensation for services performed by an election worker (for Tax Year 2022 and after).

Understanding Withholding Obligations Based on Employee Residency and Work Location

This section details the specific rules for withholding New Jersey Income Tax based on whether your employees are residents of New Jersey, nonresidents working in the state, or military personnel with New Jersey ties.

Resident Employees Working in New Jersey

As an employer in New Jersey, you are required to register, file, and pay New Jersey employer withholdings for all wages and employee compensation paid to individuals who are residents of New Jersey and are working within the state. There are no exceptions based on the location of your business; if the employee is a New Jersey resident working in New Jersey, withholding is mandatory.

Residents Working in Another State (Potential Exemption)

Under specific circumstances, you may not be obligated to withhold New Jersey Income Tax from a New Jersey resident who is working in another state. This exemption applies only if all three of the following conditions are met:

Employed Totally Outside New Jersey: The employee performs all of their work duties in a state other than New Jersey.
Subject to the Withholding Tax of That State: The employee’s wages are subject to income tax withholding in the state where they are working.
The Withholdings Required by That State Equal or Exceed the Withholdings Required for New Jersey: The amount of income tax being withheld by the other state is equal to or greater than the amount that would be required under New Jersey’s withholding rules.

Important Considerations for Residents Working Out-of-State

If the employee works only a portion of their time outside of New Jersey, or if the other state’s income tax withholding rate is lower than New Jersey’s, you must withhold New Jersey income taxes in addition to the other state’s withholdings. This ensures that the employee meets their full New Jersey resident income tax liability.

Nonresident Employees Working in New Jersey

You are required to withhold New Jersey income tax from the compensation paid to nonresident employees for the work they perform within New Jersey.

Sourcing Income for Nonresidents Working Both Inside and Outside New Jersey

If a nonresident employee works both inside and outside of New Jersey, only the portion of their compensation that is directly attributable to the work performed within New Jersey is subject to New Jersey withholding. Employers need to accurately allocate wages based on where the work was physically performed.

"Convenience of the Employer" Test for Nonresidents (Tax Year 2023 Forward)

For tax year 2023 and subsequent years, New Jersey employers may be able to establish a “convenience of the employer test” for sourcing income for certain nonresident employees. This rule applies only to employees who are residents of states that have a similar “convenience of the employer” test in their own tax laws. Under this test, if a nonresident employee works remotely from their home state for their own convenience (rather than due to a direct requirement of the New Jersey employer), their wages might be sourced to New Jersey. Employers should seek additional information from the New Jersey Division of Taxation to understand the specific states this applies to and the criteria for establishing this test.

New Jersey and Pennsylvania Reciprocal Agreement

New Jersey and Pennsylvania have a reciprocal agreement regarding income tax withholding. Under this agreement:

You are not required to withhold New Jersey income tax from the compensation paid to Pennsylvania residents who work in New Jersey, provided they file a completed Employee’s Certificate of Nonresidence in New Jersey (Form NJ-165) with you. It is your responsibility as the employer to retain the completed Form NJ-165 in your records. If a Pennsylvania resident employee does not complete and provide you with this certificate, you must withhold New Jersey income tax from their wages.
Conversely, a New Jersey resident working in Pennsylvania generally does not need to have Pennsylvania income tax withheld from their wages. Under the reciprocal agreement, employers of New Jersey residents working in Pennsylvania should generally withhold tax for these employees in New Jersey (their state of residence), not in Pennsylvania (the state where they work).

Important Note Regarding Local Wage Taxes in Pennsylvania

The New Jersey-Pennsylvania reciprocal agreement does not exempt employers from withholding any local wage taxes that may be imposed by cities, towns, or other localities within Pennsylvania. Employers should contact the Pennsylvania Department of Revenue for specific information and requirements regarding these local taxes.

Military Personnel

Military personnel whose home of record is New Jersey are generally subject to New Jersey income tax withholdings. However, an exception exists if all three of the following conditions are met:

They did not maintain a permanent home in New Jersey.
They maintained a permanent home outside of New Jersey.
They did not spend more than 30 days in New Jersey during the entire taxable year.

If any of these three conditions are not met, even if their home of record is New Jersey, their wages are subject to New Jersey income tax withholding.

Specific Rules for Military Spouses and Domestic Employers in New Jersey

This section outlines specific rules regarding New Jersey income tax withholding for military spouses working in the state and for individuals who qualify as domestic employers.

Military Spouses Working in New Jersey (Service members Civil Relief Act - SCRA)

New Jersey law, in accordance with the Service members Civil Relief Act (SCRA) as amended by the Federal Military Spouses Residency Relief Act, provides specific relief from New Jersey income tax withholding for qualifying military spouses working within the state.

Military spouses working in New Jersey are not required to have New Jersey income taxes withheld from their compensation for work performed in the state if both of the following conditions are met:

Spouse’s Military Presence: Their spouse is a member of the armed forces and is physically present in New Jersey due solely to military orders. This means the service member’s duty station is located in New Jersey.
Filing Requirements: The military spouse files both of the following with their employer:
- Form NJ-165 (Employee’s Certificate of Nonresidence in New Jersey)
- A copy of their valid spousal military identification card.

By providing these documents to their employer, the military spouse can claim exemption from New Jersey income tax withholding on their wages earned in New Jersey. Employers are responsible for retaining these forms in their records. It’s crucial to understand that this exemption is tied to the service member’s presence in New Jersey due to military orders and the spouse’s residency in another state.

Domestic Employers

If you employ a household worker, you may be classified as a domestic employer. Common examples of household workers include:

Nannies
Caretakers
Housekeepers
Butlers
Groundskeepers
and other similar roles providing services within or around a private home.

Federal Withholding for Domestic Employers

The Internal Revenue Service (IRS) provides guidance to determine if you are required to withhold federal income taxes, Social Security tax, and Medicare tax from the wages you pay to your household employees. You should consult the IRS guidelines and publications for specific criteria.

New Jersey Withholding for Domestic Employers (Tied to Federal Withholding)

In New Jersey, if you, as a domestic employer, are required to withhold federal income taxes from your household employee’s wages, then you must also withhold New Jersey income taxes.

Employee Choice for New Jersey Withholding (Even Without Federal Mandate)

Even if you are not federally mandated to withhold taxes for your household employee, your employee has the option to:

Request New Jersey income taxes be withheld from their wages.
Claim they are exempt from the New Jersey income tax withholding requirement (though they would still be responsible for paying any applicable state income tax when they file their personal income tax return).

It is advisable to have a clear agreement with your household employee regarding New Jersey income tax withholding.

Filing and Payment Requirements for Domestic Employers

If you determine that you are a domestic employer and are required to withhold New Jersey income taxes (because you are also withholding federal taxes), you are generally required to file and pay these withholdings annually. You will need to obtain a New Jersey Employer Identification Number to remit these payments. The specific form and deadline for annual filing will be outlined by the New Jersey Division of Taxation. Domestic employers should consult the relevant instructions and publications provided by the state for detailed filing and payment procedures.
