Whether someone who works for you is an employee or an independent contractor is not a choice you and the worker make by agreeing on a label. It depends on the facts of how the work is actually done. The IRS looks at the whole relationship, and no single factor settles it.
The three groups of factors the IRS uses
- Behavioral control: does the business direct how, when and where the work is done, and does it train the worker? More control points toward employee.
- Financial control: who pays for tools and equipment, who bears unreimbursed expenses, whether the worker can make a profit or a loss, and whether they offer their services to other businesses. A worker with their own investment and other customers looks more like a contractor.
- Type of relationship: written contracts, benefits such as insurance or paid leave, whether the arrangement is ongoing, and whether the work is a key part of the business.
What the classification changes
| Employee (W-2) | Contractor (1099) | |
|---|---|---|
| Income tax and payroll taxes | You withhold them and pay your share | The worker handles their own, including self-employment tax |
| Year-end form | Form W-2 | Form 1099-NEC, if payments reach the reporting threshold |
| Paperwork at the start | Form W-4 | Form W-9 |
| Unemployment insurance and workers compensation | Generally required | Generally not, if the classification is correct |
Why it matters
Treating an employee as a contractor can leave the business owing the payroll taxes it should have withheld, plus penalties and interest. Some states apply stricter tests than the IRS for certain purposes, and New Jersey is one of them for unemployment and wage rules, so a worker who passes the federal test may still be an employee under state law.
A note for trucking businesses
Owner-operators who lease their own truck to a carrier and bear their own fuel, maintenance and insurance costs are often treated as contractors. A driver who operates a company truck under company dispatch is often an employee. Those are tendencies, not rules: the actual arrangement decides.
