Hiring help raises one question before the first payment: is this person a W-2 employee or a 1099 contractor? The answer decides who pays which taxes, which forms you file, and how much risk the business carries. The wrong answer is expensive, and in New Jersey the rules are stricter than in most states. This guide explains the difference, the federal and New Jersey tests, what each worker really costs, and what to do if you are not sure.
W-2 vs 1099 at a glance
| W-2 employee | 1099 independent contractor | |
|---|---|---|
| Who controls how the work is done | The business | The worker |
| Income tax withholding | Business withholds from each paycheck | None; the worker pays their own estimated tax |
| Social Security and Medicare | Split: 7.65% from the worker, 7.65% from the business | The worker pays both halves as self-employment tax (15.3%) |
| Unemployment and disability taxes | Business pays federal and New Jersey contributions | None |
| Forms you collect | W-4, NJ-W4, Form I-9 | Form W-9 |
| Forms you file | Payroll returns every quarter, W-2 by January 31 | Form 1099-NEC by January 31, if paid $2,000 or more |
| Benefits, overtime, minimum wage | Apply | Do not apply |
| Typical arrangement | Ongoing, part of the core business, your schedule and tools | Project-based, their own business, their own tools and clients |
How the IRS decides: the common-law test
Calling someone a contractor, or having them sign a contractor agreement, does not settle anything. The IRS looks at the whole relationship, and says that “all information that provides evidence of the degree of control and independence must be considered.” It groups the evidence into three categories:
- Behavioral control. Does the business control, or have the right to control, what the worker does and how they do it? Detailed instructions, required hours, training in your methods and performance reviews point toward an employee.
- Financial control. Does the business control the business side of the job? Look at how the worker is paid (hourly wage or a fee per project), whether expenses are reimbursed, who provides tools and supplies, and whether the worker can make or lose money on the job.
- Type of relationship. Are there written contracts or employee-type benefits such as insurance, a pension plan or vacation pay? Is the relationship expected to continue, and is the work a key part of the business?
No single factor decides it. Publication 15-A gives more examples by industry.
If you genuinely cannot tell, either the business or the worker can file Form SS-8 to ask the IRS for an official determination. The IRS warns it can take at least six months.
New Jersey’s ABC test is stricter
New Jersey uses the ABC test in its unemployment compensation law (N.J.S.A. 43:21-19(i)(6)). Under it, a worker is an employee unless the business can show all three of the following, according to the NJ Department of Labor:
- A. The individual has been and will continue to be free from control or direction over the performance of the work, both under the contract and in fact.
- B. The work is either outside the usual course of the business, or performed outside of all the places of business of the enterprise.
- C. The individual is customarily engaged in an independently established trade, occupation, profession or business.
Part C is where many small businesses fail the test. A person who works only for you, has no other clients and no business of their own is hard to treat as a contractor in New Jersey, even if they set their own hours. A worker can pass the IRS test and still be an employee under New Jersey’s test, so check both.
What each worker really costs
The tax difference is real, and it is why misclassification is tempting. For an employee in New Jersey, the business pays on top of wages:
- 7.65% employer Social Security and Medicare (the 6.2% part stops at the 2026 wage base of $184,500),
- federal unemployment tax (FUTA), usually $42 a year per employee after the state credit, and
- New Jersey unemployment, disability and workforce contributions. For a new employer in 2026 these add up to about 3.3% of the first $44,800 of each employee’s wages.
Example: a new New Jersey employer paying a $50,000 salary owes roughly $3,825 of employer FICA, $42 of FUTA and about $1,478 of New Jersey contributions, a total of about $5,345, or 10.7% on top of wages. That is before workers’ compensation insurance and any benefits. A contractor paid $50,000 costs the invoice amount. The NJ paycheck calculator at the end of this article shows the employer cost for any salary.
The worker sees the other side: a contractor pays the full 15.3% self-employment tax and makes quarterly estimated payments. Good contractors price that into their rates.
Paperwork for each
Hiring an employee in New Jersey:
- collect Form W-4, Form NJ-W4 and Form I-9,
- register as an employer with the state and set up payroll,
- withhold and deposit taxes on schedule, file Form 941 each quarter and New Jersey’s quarterly returns, and
- give each employee a Form W-2 by January 31.
Paying a contractor:
- collect a Form W-9 before the first payment. It gives you the contractor’s name, tax classification and taxpayer identification number,
- keep invoices and payment records, and
- file Form 1099-NEC by January 31 if you paid them $2,000 or more during the year. That threshold applies to payments made from 2026 onward; it was $600 before (IRS instructions). Payments to corporations are generally exempt, except attorney fees.
If a contractor will not give you a taxpayer identification number, you may have to apply backup withholding at 24% to their payments. Contractors who live outside the U.S. give a Form W-8BEN instead of a W-9 and do not get a 1099.
Our 1099 filing service collects the W-9s during the year and files the forms on time.
What misclassification costs
If you treat an employee as a contractor without a reasonable basis, the IRS says you may be held liable for the employment taxes for that worker. That means the income tax you should have withheld, both halves of Social Security and Medicare, and federal unemployment tax, plus interest and penalties.
New Jersey adds its own consequences under its misclassification laws:
- unpaid wages, overtime and benefits owed to the worker,
- a penalty of up to $250 per misclassified employee for a first violation and up to $1,000 per misclassified employee for each later violation,
- up to 5% of the worker’s gross earnings over the past 12 months, paid to the worker, and
- unpaid unemployment and disability contributions to the state.
If you realize workers were misclassified, the IRS Voluntary Classification Settlement Program lets eligible businesses reclassify them as employees going forward with partial relief from federal employment taxes. Fixing it early is almost always cheaper than waiting for an audit or an unemployment claim to trigger a review.
Common mistakes
- Relying on the contract. A signed “independent contractor agreement” does not make someone a contractor if the facts say otherwise.
- Paying a full-time, long-term worker on a 1099. Fixed hours, your tools and no other clients usually point to an employee, especially under New Jersey’s Part C.
- Not collecting a W-9 up front. Chasing it in January delays the 1099 and can trigger backup withholding.
- Using the old $600 threshold for 2026 payments, or forgetting that attorney fees are reportable even to corporations.
- Switching a worker from W-2 to 1099 with no change in the work itself.
Getting it right
Most small businesses need both: a few employees on payroll and contractors for specialized or one-off work. The goal is to classify each one correctly from the start and keep the paperwork that supports it. We set up and run payroll for New Jersey businesses, collect W-9s and file 1099s, and keep the books that show who was paid what. Worker classification can also be a legal question. For a disputed or high-risk case, talk to an employment attorney as well. A free 15–30 minute consultation is a good place to start.
