How to Hire Employees in New Jersey: The Complete Compliance Sequence

The first New Jersey hire I was involved in started on a Monday. The workers compensation policy took effect that Thursday. Nobody got hurt, nothing came of it, and I only understood later what those three days had actually been: a period in which the business was operating as an uninsured employer in a state that treats failure to insure as a criminal offense and prices it in ten day blocks.

That is the pattern with New Jersey. Almost nothing here is hard on its own. The state registration is one online form. The new hire report takes five minutes. What catches employers is order and timing, because several of the steps have to be finished before a person legally starts working, and the ones with the highest price tags are the ones that feel like paperwork.

This guide walks the sequence in the order the work actually happens, from the federal EIN through the ninetieth day. If you are doing this for the first time anywhere, read it next to the general first employee checklist. I built FirstHR because the failure mode at a business without an HR department is never ignorance of the rule. It is the calendar.

The New Jersey Hiring Sequence at a Glance

Every step below is a legal obligation with an agency attached and a consequence for missing it. Four of them have to be complete before the employee performs any work, which is the part most first time employers discover too late.

Read the exposure column once before you plan the start date. New Jersey stacks a state layer on top of every federal requirement, and two of those layers, workers compensation and the ABC test for classification, are stricter here than in most of the country.

Step 1: Get Your Federal EIN

The federal Employer Identification Number comes first because the New Jersey registration is keyed to it. Apply through the IRS online application, which issues the number in the same session during operating hours. There is no fee and no waiting period.

If you already hold an EIN from forming the entity, reuse it. If you have been running as a sole proprietor and reporting under your Social Security number, you need one now, because employment tax reporting and the state registration both require it.

Step 2: File Form NJ-REG With the Division of Revenue

New Jersey employer registration happens through Form NJ-REG, filed with the Division of Revenue and Enterprise Services in the Department of the Treasury. The state instructs businesses to complete it at least 15 business days before doing business in New Jersey, which is the single most useful date in this guide: it means the registration should be filed before you finish interviewing, not after the offer is accepted.

One filing does two jobs. It registers you for the taxes administered by the Division of Taxation, which for an employer means gross income tax withholding, and it registers you for the liabilities administered by the Department of Labor and Workforce Development, which means unemployment, temporary disability, and family leave insurance. You file online through the Division of Revenue registration portal.

Corporations, LLCs, and limited partnerships file the public records formation or authorization document first, then the NJ-REG. Sole proprietors and general partnerships go straight to the NJ-REG. Either way you receive a New Jersey tax identification number and can print a Business Registration Certificate shortly after submission.

What the NJ-REG Filing Does Not Cover

Registration is a tax and labor filing, not a general permission slip. It does not form the entity, so an LLC or corporation still needs its formation or authorization filing on record first. It does not obtain workers compensation coverage, which is a separate purchase from an insurance carrier. It does not handle municipal business licensing, and it does not replace any professional or industry license the work itself requires.

It also does not tell you which local payroll taxes apply. If your workplace sits in Jersey City or Newark, those city obligations run alongside the state accounts and are registered with the city, not with Trenton. Sort that out before the first pay run rather than after a city notice arrives.

Step 3: Understand the Four Payroll Accounts You Just Opened

The NJ-REG filing creates four contribution obligations, and New Jersey is unusual in that employees fund a large share of them through payroll deductions rather than the employer carrying the whole cost. Knowing the split before the first paycheck prevents the awkward conversation about why a New Jersey check has more line items than a check from a neighboring state.

Rates come from the Division of Employer Accounts schedule: worker rates are set for calendar 2026, and the new employer rates shown apply to the fiscal year running July 1, 2026 through June 30, 2027. New employers other than successors stay on the new employer rate for the first three calendar years, after which the state assigns a calculated rate based on your own experience.

Combined, a new employer pays roughly 3.3 percent on the first $44,800 of each employee wages. That is your true state unemployment cost before federal FUTA. Family leave insurance costs the employer nothing directly, because New Jersey family leave insurance is worker funded, but the job protection that surrounds it is now a real obligation for small employers.

Reporting happens quarterly on Form NJ-927 and Form WR-30, both filed electronically, due by the thirtieth day of the month after each quarter ends. Miss the filing and penalties attach to the report, not just to the payment. The mechanics of rate notices, deposit schedules, and provider choices are covered in the New Jersey payroll guide.

What Your Employee Sees on the First Check

A New Jersey pay stub carries more deduction lines than most employees expect, and someone relocating from a state without disability or family leave insurance will ask about them. Beyond federal income tax, Social Security, and Medicare, the check shows New Jersey gross income tax withholding plus the worker share of unemployment, workforce development, disability, and family leave insurance.

None of those state deductions is optional and none of them is an employer fee, but that distinction is invisible on a stub unless somebody explains it. Two sentences in your onboarding packet naming the deductions and what each one buys will prevent the payroll question that otherwise arrives on day two of every hire.

Step 4: Put Workers Compensation Coverage in Force

New Jersey requires every employer not covered by a federal program to carry workers compensation insurance or to be approved for self-insurance. There is no elective option, no employee count threshold, and no grace period for the first hire. The Division of Workers Compensation states the requirement applies to corporations, partnerships, LLCs, and sole proprietorships alike once anyone performs services for compensation.

Coverage has to come from a carrier authorized to write it in New Jersey, and the policy must name New Jersey. An out of state policy issued for your home state does not automatically extend, and the state cross matches databases between agencies to find employers who never bound a policy.

Practically, this means the binder date belongs on the pre-start checklist next to the offer letter. If the policy takes effect the same week the employee starts rather than before, you have created exposure that no amount of later paperwork can retroactively close.

Who Is Not Counted as an Employee for Coverage

State materials draw the line at people who work for themselves. A sole proprietor operating alone, the partners in a partnership, and the members of an LLC are not employees of their own business, so a business with no one else on the payroll has nothing to insure. The obligation attaches the moment anyone other than those owners performs services for compensation, including part time and seasonal help.

Two situations catch employers off guard. Officers of a corporation are generally treated as employees of that corporation even when they own it, and a contractor who fails the state classification test is treated as your employee for coverage purposes, which means an uninsured injury claim can arrive from someone you never considered part of the team.

Step 5: Write the Posting and the Offer to New Jersey Rules

New Jersey regulates the hiring process itself, not just the employment relationship that follows. Three rules shape the posting and the screen: pay transparency, the salary history ban, and the Opportunity to Compete Act.

Since June 1, 2025, covered employers must include in every posting for a new job or transfer opportunity the hourly wage or salary, or a range, plus a general description of benefits and other compensation programs the employee would be eligible for. The requirement covers employers with 10 or more employees over 20 calendar weeks that do business, employ people, or accept applications in the state, and it applies to out of state employers hiring New Jersey residents. Penalties run up to $300 for a first violation and up to $600 for each violation after that.

The same law requires reasonable efforts to notify current employees in the affected department of promotional opportunities before a promotion decision is made. That internal duty is the part small employers skip, because a promotion rarely feels like a posting.

Salary history has been off limits since January 1, 2020. Employers may not screen applicants based on prior wages, salaries, or benefits, or require salary history to satisfy any minimum or maximum criteria. If a candidate volunteers the information without prompting, you may consider and verify it, but a refusal to share cannot count against them. Civil penalties reach $1,000 for a first violation, $5,000 for a second, and $10,000 for each one after.

Criminal history is governed by the Opportunity to Compete Act, which bars covered employers from asking about a candidate criminal record during the initial application process, in writing or verbally. That window closes once you have conducted a first interview. The safer pattern is the one described in our guide to ban the box hiring: move any background inquiry to after a conditional offer, and apply the same rule to every candidate.

Interview questions sit under the Law Against Discrimination, which applies to employers of every size in New Jersey and covers a broader list of protected characteristics than federal law does. Keep questions job related, ask the same ones in the same order of every candidate, and record the answers on a scored form. A structured interview is not only better hiring practice, it is the documentation that makes a rejected candidate complaint answerable months later when nobody remembers the conversation.

The offer letter itself should state the rate of pay, the pay frequency, the position, and whether the role is exempt. New Jersey requires wages to be paid at least twice per calendar month on regular paydays designated in advance, with a narrow exception allowing monthly payment for bona fide executive, supervisory, and similar classifications.

Step 6: Verify Work Authorization With Form I-9

Every employer in the United States completes Form I-9 for every new hire, and New Jersey adds no state verification program on top of it. The employee completes Section 1 no later than the first day of work. You complete Section 2 within three business days of the start date, after physically or remotely examining documents the employee chooses from the list of acceptable documents.

You cannot tell the employee which documents to present. Specifying documents by national origin or citizenship status is its own violation, separate from any paperwork error. Our explainer on work authorization covers what each document category proves and where the common mistakes sit.

Civil money penalties for paperwork violations are assessed per form and per employee, and the range published at 8 CFR 274a.10 runs from $288 to $2,861 for each individual. Immigration and Customs Enforcement gives an employer at least three business days to produce the forms after a notice of inspection, then at least ten business days to fix technical or procedural failures. Anything still uncorrected when that window closes is treated as a substantive violation.

E-Verify in New Jersey

New Jersey does not require private employers to use E-Verify. Unlike states that have layered a verification mandate on top of the federal system, New Jersey leaves participation voluntary, so the I-9 is the whole state level obligation for an ordinary private employer. Federal contractors are a separate case, because the federal contract clause that requires E-Verify comes from the contract, not from state law.

If you do enroll voluntarily, use it consistently. Running it for some hires and not others, or running it before an offer, creates a discrimination exposure that the program was never meant to produce.

Retention deadlines are worth calendaring at hire rather than reconstructing later. The broader schedule for payroll, tax, and personnel documents sits in our guide to how long to keep employee records.

Step 7: Collect Both Withholding Forms Before the First Paycheck

New Jersey has a state gross income tax, so the federal Form W-4 is only half the job. Each new hire also completes Form NJ-W4, the Employee Withholding Allowance Certificate, which selects the state withholding rate table the employer applies. Employers must furnish the form and withhold at the rate the employee chooses.

The rate table selection matters more here than the equivalent choice in most states, because New Jersey tables are built around household filing situations. A two income household that leaves the default in place frequently under withholds and finds out in April. Explaining the difference between payroll tax and income tax during onboarding takes two minutes and prevents a complaint that lands on you rather than on the state.

Collect both forms with the offer packet rather than on the first morning. Every form that arrives before day one is a form that is not competing with introductions, equipment setup, and the first team meeting.

Step 8: File the New Hire Report Within 20 Days

New Jersey law at N.J.S.A. 2A:17-56.61 requires every employer to report each newly hired or rehired employee to the New Jersey State Directory of New Hires within 20 days of the date of hire. The duty covers full time, part time, and temporary employees who live or work in the state, and it exists to support child support enforcement, which is why the reporting portal is run through the child support employer services program.

The report carries eight data elements: your business name, address, and federal EIN, plus the employee name, address, Social Security number, date of birth, and date of hire. New Jersey also asks that an independent contractor transacting business in the state be reported as a new hire, which surprises most employers. Employers who transmit electronically may file two monthly transmissions 12 to 16 days apart instead of reporting each hire individually. The 20 day rule and the reporting portal are documented by New Jersey Child Support.

The penalty is small, up to $25 per unreported employee, with a higher amount where employer and employee conspire not to report. The reason to care is not the fine. It is that a missing new hire report is the kind of gap that turns a routine audit into a broader one, and it takes five minutes to close.

What Counts as the Date of Hire

The clock starts on the first day the employee performs services for pay, not the day the offer was signed and not the day the paperwork was completed. If a start date slips by two weeks, the 20 day window slips with it, which is why the report belongs next to the I-9 in your day one task list rather than in a monthly cleanup routine.

Rehires count as new hires. An employee who separates and later returns has to be reported again, and so does a seasonal worker coming back for another season. Employers who run seasonal crews tend to report the first cohort correctly and forget the returning ones entirely.

Step 9: Deliver the Notices, Then Run the First 90 Days

New Jersey splits its notice obligations into two kinds, and employers who treat them as one kind get the second kind wrong. Some notices are posted. Others must be handed to the employee individually, and posting them does not satisfy the duty.

The complete state set is published as a single employer poster packet by the Department of Labor and Workforce Development, and the federal posters come from the US Department of Labor. Both are free. There is no reason to buy a poster service for a single location.

Compliance ends there. Onboarding starts. Everything above gets the person legally onto payroll and none of it makes them productive, which is why the first 90 days deserve the same structure as the first 20 days.

This is the workflow I built FirstHR around. The offer goes out with e-signature, the I-9, W-4, NJ-W4, and state notices are collected digitally before day one, the three day and 20 day deadlines become tasks with reminders, and the AI onboarding wizard turns the job description into a 30-60-90 day plan instead of a blank page. FirstHR is an onboarding and HR platform, not a payroll provider.

New Jersey Rules That Change How You Hire

Six state rules materially change hiring decisions here compared with most of the country. They affect what you put in the employee handbook, how you budget wages, and how much flexibility you have when a role does not work out.

Employment in New Jersey is at will, but the exceptions are broader than in the strongest at will states. The Law Against Discrimination reaches employers of every size and covers a long list of protected characteristics, and the Conscientious Employee Protection Act gives employees a retaliation claim for reporting activity they reasonably believe is unlawful. Neither has a headcount floor.

Final wages follow the payday rule rather than an immediate payment rule, which makes New Jersey more forgiving than states that require same day payment. The mechanics of that calculation, including accrued leave treatment, are covered in our guide to the final paycheck for a terminated employee.

Two more state programs arrive as the team grows rather than at the first hire. Group terminations are governed by the state mass layoff statute, explained in our New Jersey WARN Act guide, and employers without a qualified retirement plan eventually fall under the RetireReady NJ mandate, whose coverage threshold the state has been lowering.

Neither is a first-hire problem, but both are cheaper to plan for than to retrofit. The rest of the state picture, from the discrimination statute through leave, wage, and termination rules, sits in our New Jersey compliance hub.

City Requirements: Jersey City and Newark

Two New Jersey cities add obligations that are easy to miss because they are municipal rather than state. Both are payroll and posting matters, not licensing matters, so they surface on the first paycheck rather than at formation.

Jersey City imposes a payroll tax of one percent of gross payroll on employers located in the city. Wages of Jersey City residents are exempt, employers with quarterly gross payroll below $2,500 are exempt, and the tax may not be deducted from employee wages. Returns are filed quarterly. Jersey City has also adopted its own pay transparency ordinance covering job postings, so an employer inside the city should check the local rule against the state one rather than assume the state threshold governs.

Newark imposes a payroll tax of one percent of wages for services performed within the city, with a reduced rate of half a percent available to employers who document that more than half their workforce lives in Newark. Newark returns are also quarterly, due by the thirtieth day after the quarter ends. Newark separately maintains local hiring requirements that apply to contractors doing business with the city.

The two cities treat residency in opposite directions, which matters for a remote or hybrid hire. Jersey City takes the wages of city residents out of the tax base entirely. Newark instead halves the rate for an employer that can document a majority resident workforce. A payroll setup that treats the two ordinances as one rule will get one of them wrong, so document the primary work location in the offer letter before a city ever has to ask.

One thing that no longer applies: the municipal paid sick leave ordinances that a dozen New Jersey cities adopted before the statewide Earned Sick Leave Law took effect. The state law replaced them, so a single sick leave policy now works statewide.

Employee or Contractor: New Jersey Uses the ABC Test

New Jersey applies the ABC test from the Unemployment Compensation Law at N.J.S.A. 43:21-19(i)(6), and the hiring business carries the burden of proving all three prongs. Fail one and the worker is an employee, no matter what the agreement says or who asked for the arrangement.

Prong B decides most disputes. A design studio that pays a plumber on a 1099 is on solid ground. The same studio paying a designer on a 1099 is not, because design is the usual course of its business. Our comparison of employee versus contractor status walks through the fact patterns in more detail.

The written agreement does not settle the question. A contract that calls someone an independent contractor, recites that they carry their own insurance, and waives every employee benefit is evidence about prong A at best, and it does nothing for prongs B and C. Auditors look at how the relationship ran: who set the hours, whose equipment was used, whether the person invoiced other clients, whether there was a business entity behind the invoices.

A reclassification reaches backward. The state assesses unpaid unemployment, disability, and family leave contributions with interest and penalties, and wage and hour claims often follow, because a worker who was an employee all along was also entitled to overtime and earned sick leave. New Jersey also requires every employer, regardless of size, to post the misclassification notice, which tells workers exactly how to file the complaint that starts the process.

The Mistakes That Cost New Jersey Employers the Most

These five account for most of what goes wrong at small New Jersey employers hiring for the first time. Every one is a timing or template problem rather than a knowledge problem.

Notice the pattern. Nobody in these scenarios disagreed with the rule. The workers compensation policy was ordered. The application form was inherited. The notice was in the packet somewhere. Compliance at a business without a dedicated HR person fails on sequencing, which is exactly the kind of failure that a checklist with dates attached prevents.
