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. Misclassifying employees as contractors under NJ's strict ABC test is one of the most common and costly payroll compliance errors. Greg Monaco, CPA provides NJ payroll processing that handles all federal and state requirements.

Key Takeaway

NJ payroll has more requirements than most states. The key compliance items are using the NJ-W4 (not the federal W-4), correctly calculating NJ-specific contributions (UI, DI, FLI, workforce development), reporting new hires within 20 days, and properly classifying workers under NJ's ABC test. Getting payroll wrong is expensive: back taxes, penalties, and potential worker misclassification claims.

## 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 outside the usual course of business or performed off-premises, and (C) the worker is customarily engaged in an independent business. NJ's test is stricter than the federal standard, and misclassification penalties are severe.

How often do I need to file NJ payroll tax returns?

NJ payroll taxes are reported quarterly on Form NJ-927 and Form WR-30, due by the last day of the month following each quarter. 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), NJ-W-3 (due February 15), 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.
