Employee or Contractor? How to Tell the Difference

"Just put them on a 1099" might be the most common — and most expensive — shortcut in small business. It feels simpler: no payroll taxes, no benefits, less paperwork. But whether someone is an employee or an independent contractor isn't really your choice to make. The nature of the work decides it, and getting it wrong can cost you far more than you saved.

Quick note before we dig in: this is general guidance, not legal or tax advice. Classification rules are genuinely complex and vary by state, so treat what follows as a map — and when a real decision is on the line, check with an accountant or employment attorney.

Why this matters more than it looks

When a worker is misclassified as a contractor but should have been an employee, the bill can include back payroll taxes, penalties and interest, unpaid overtime or minimum wage, and sometimes back benefits. The IRS, the Department of Labor, and state agencies all take this seriously, and they don't need you to have meant any harm. It's one of the easiest ways for a well-intentioned small business to land in costly trouble.

The core question: who controls the work?

Underneath all the rules is one idea — control and independence. An employee works under your direction: you decide how, when, and where the work gets done. A contractor runs their own business and controls how they deliver a result. With a contractor, you're a client, not a boss.

Hold onto that distinction, because it's what the official tests are really measuring.

What the IRS looks at

The IRS uses a "common law" framework that groups the evidence into three areas:

Behavioral control. Do you direct how the work is done — set their hours, require your methods, provide the tools, supervise them? The more control you have, the more it looks like employment. Financial control. Who runs the business side? A true contractor typically invests in their own equipment, can work for other clients, can make a profit or take a loss, and is often paid by the project rather than a steady wage. Relationship. Is the arrangement ongoing and indefinite, or project-based? Are there benefits? Is the work a core part of what your business does? A written contract helps show intent, but it doesn't settle the question on its own.

No single factor decides it. It's the whole picture that matters.

Some states are stricter (the "ABC test")

Here's a big one that trips people up: many states — California, Massachusetts, and New Jersey among them — use a stricter "ABC test." Under it, a worker is presumed to be an employee unless the business can prove all three of these: (A) the worker is free from your control, (B) the work is outside the usual course of your business, and (C) the worker is running an independently established trade or business.

That's a much higher bar. Someone who might pass as a contractor under federal rules could still be an employee under your state's test. So where you operate matters a lot — another reason to confirm the specifics for your state.

Common mistakes small businesses make

Assuming part-time or temporary means contractor. It doesn't. Plenty of part-time and short-term workers are employees. Letting a "contractor" quietly become an employee. Someone who works only for you, on your schedule, with your equipment, for months on end is a classic misclassification — no matter what the original agreement said. Believing a signed contractor agreement settles it. It shows intent, but if the day-to-day looks like employment, the paperwork won't save you. Using 1099 mainly to skip payroll taxes and benefits. Tempting, and exactly the pattern agencies look for.

A simple gut check (not a legal test)

If you find yourself controlling when, where, and how someone works, folding them into your team long-term, and they don't really work for anyone else — they probably look like an employee, whatever the paperwork says.

When you're genuinely unsure, the safer default is usually to treat someone as an employee. But this is precisely the kind of call worth running past an accountant or employment attorney first. The cost of a quick professional opinion is tiny next to the cost of getting it wrong.
