What is the difference between a contractor and an employee?

It comes down to control and independence. An employee works under your direction, as part of your core business, on an ongoing basis. A true independent contractor runs their own business, controls how the work is done, and typically serves multiple clients. The label on the agreement does not decide it; the facts do.

What test determines worker classification?

The federal economic-reality test (used by the Department of Labor and the IRS's own factors) looks at control, investment, permanence, and whether the work is integral to your business. Some states use a stricter ABC test that presumes employee status unless you prove all three prongs, with California the best-known example.

What is the ABC test?

A stricter standard used in California and some other states. A worker is an employee unless you can prove all three: (A) they are free from your control, (B) they do work outside your usual business, and (C) they are in an independently established trade. Prong B is the hard one; it means someone doing your core work generally cannot be a contractor.

What are the penalties for misclassifying a contractor?

Significant: back employment taxes, back overtime and minimum wage, unpaid benefits, and penalties from both the IRS and state agencies. Because it compounds across every pay period and every misclassified worker, it is often the single most expensive HR mistake a small business makes.

Independent Contractor vs. Employee: The 2026 Rules

The contractor-versus-employee question is deceptively simple to get wrong. You need help, someone is willing to work as a 1099 contractor, you both sign an agreement that says "independent contractor," and it feels settled. It is not. Whether a worker is a contractor or an employee is determined by law, based on the actual facts of the relationship, no matter what the agreement says or what both parties prefer. And the cost of getting it wrong is steep enough that it deserves real attention.

Why the label does not decide it

You cannot contract your way out of employee status. If the facts of the work say someone is an employee, they are an employee for tax and wage purposes, even with a signed contractor agreement and even if the worker wanted 1099 treatment. Regulators look past the paperwork to how the relationship actually works. This is the core thing small businesses miss.

The federal test: control and economic reality

Federal agencies (the Department of Labor for wage law, the IRS for taxes) look at the economic reality of the relationship. A worker leans toward employee the more these are true:

You control how, when, and where the work gets done, not just the result.
The work is part of your core business rather than a distinct, outside project.
The relationship is ongoing rather than project-based.
The worker depends on you economically and does not really run their own business serving multiple clients.
You provide the tools, equipment, and training.
The worker has no real opportunity for profit or loss based on their own managerial skill.

No single factor decides it. Regulators weigh the whole picture, and the center of gravity is control and independence.

The ABC test: stricter, and spreading

Some states, most notably California, use the ABC test, which is much harder to satisfy. Under it, a worker is presumed to be an employee unless the business proves all three of these:

A. The worker is free from the company's control and direction in performing the work.
B. The worker performs work outside the usual course of the company's business.
C. The worker is customarily engaged in an independently established trade or business of the same type.

Prong B is the one that catches people. If a worker is doing your core business work, a marketing agency using a "contractor" marketer, a cleaning company using "contractor" cleaners, they generally fail prong B and are employees under the ABC test, full stop. In ABC-test states, contractor status is much narrower than most owners assume.

Because states differ, a worker you classify correctly as a contractor under federal law can still be misclassified under a particular state's stricter rules. If you have workers in multiple states, you have to check classification state by state. (See our multi-state compliance guide.)

Why misclassification is so expensive

When a contractor is reclassified as an employee, the bill is large because it compounds. You can owe back employment taxes you never withheld or paid, back overtime and minimum wage under the FLSA, unpaid benefits the worker should have been eligible for, and penalties from both the IRS and state agencies. Multiply that across every pay period the misclassification ran and every worker it applied to, and a casual 1099 arrangement can turn into a five- or six-figure liability. This is why it is consistently one of the costliest small-business HR mistakes.

How to get it right

Classify based on the real facts, not the arrangement you would prefer, before the first payment.
Check your state's test, especially if you operate in California or another ABC-test state, or hire across state lines.
Re-examine long-running contractor relationships. A contractor who has worked mostly for you, full-time, for a year looks a lot like an employee regardless of how it started.
When it is close, get a professional read. The cost of a review is trivial next to the cost of reclassification. (Our classification guide has a worksheet to work through your roles.)

The bottom line

Contractor versus employee is decided by the facts of the work, not the contract or either party's preference, and the ABC-test states make true contractor status narrow. Get the classification right up front, check it state by state, and revisit arrangements that have drifted. If you want a professional review of how your workers are classified, especially across states, that is exactly the kind of thing we do.
