Running payroll in New Jersey involves more than federal income tax withholding and FICA. NJ requires separate state income tax withholding (using its own NJ-W4, not the federal W-4), unemployment insurance, temporary disability insurance, family leave insurance, workforce development contributions, and transit benefits for businesses with 20 or more employees. Worker classification requires a separate NJ ABC-test analysis. The client or selected payroll provider must handle all federal and state processing requirements.
Running payroll in NJ involves more than federal withholding and FICA.
What NJ Payroll Taxes Must Employers Withhold?
Income tax withholding, unemployment insurance, disability insurance, family leave insurance, workforce development contributions, and any applicable transit-benefit requirements can depend on employer and worker facts. Tipped-worker reporting requires separate current-rule review.
What Are the Key NJ Payroll Filing Requirements?
Most covered non-domestic employers file Form NJ-927 (or NJ-927-W for a designated weekly payer) and Form WR-30 quarterly; eligible domestic employers follow the applicable annual NJ-927-H schedule. Form NJ-W-4 is New Jersey's withholding certificate, separate from federal Form W-4, and annual wage and reconciliation filings remain separate.
What Are the NJ New Hire Reporting Requirements?
Submit the required report to the NJ New Hire Reporting Center within 20 days of hiring, rehiring, returning to work, or contracting. An employer or other reporting entity that transmits magnetically or electronically reports every 15 days under the governing rules. Current N.J.S.A. 2A:17-56.61, as amended by P.L. 2025, c.361 effective January 20, 2026, also covers a person contracted to work in New Jersey whom the entity pays or anticipates paying earnings or other financial compensation, including earnings reported on Form 1099; do not apply a $600 floor.
Which NJ Payroll Compliance Items Require Review?
Misclassifying employees as contractors (NJ's ABC test is strict), using federal W-4 instead of NJ-W-4, and miscalculating NJ-specific contributions.
Key Takeaway
NJ payroll has state-specific requirements in addition to federal payroll rules. Review the NJ-W4, applicable UI, DI, FLI and workforce-development contributions, new-hire reporting deadlines, and worker classification under the NJ ABC test. The consequence of an error depends on the obligation, period, amounts, correction, and enforcement facts.

Frequently Asked Questions
What payroll taxes does NJ require employers to withhold?
NJ employers must withhold state income tax (using the NJ-W4, not the federal W-4), and employees contribute to unemployment insurance (UI), temporary disability insurance (TDI), family leave insurance (FLI), and workforce development/supplemental workforce fund. Employers also pay their share of UI and disability contributions. These obligations are in addition to federal income tax withholding, Social Security, and Medicare.
What is the NJ ABC test for employee classification?
Under NJ's ABC test, a worker is presumed to be an employee unless the employer can prove all three conditions: (A) the worker is free from control or direction, (B) the service is either outside the usual course of the employer's business or performed outside of ALL the employer's places of business (N.J.S.A. 43:21-19(i)(6)(B) - merely working off-site is not automatically enough, because "places of business" can extend to locations where the enterprise operates), and (C) the worker is customarily engaged in an independent business. NJ's test differs from the federal standard; any liability or remedy depends on the applicable statute, classification facts, procedure, and amounts involved.
How often do I need to file NJ payroll tax returns?
Most covered non-domestic NJ employers report quarterly on Form NJ-927 (or NJ-927-W for a designated weekly payer) and Form WR-30, due by the 30th day of the month following each quarter (April 30, July 30, October 30, January 30). Eligible domestic employers follow the applicable annual NJ-927-H schedule. Federal payroll taxes are deposited on a semi-weekly or monthly schedule depending on your total tax liability. Year-end forms include federal W-2s (due January 31), electronically filed Form NJ-W-3 (due February 15, or the next business day when February 15 falls on a weekend or holiday), and Form 940 (annual federal unemployment, due January 31).
Do NJ employers need to provide transit benefits?
NJ employers with 20 or more employees must offer pre-tax transit benefits under the NJ transit benefit requirement. This allows employees to use pre-tax dollars for public transportation and vanpool expenses. The requirement does not mandate that employers pay for transit, only that they offer the pre-tax benefit through payroll deduction.
