General legal information, published for everyone. It does not apply the law to anyone’s particular situation and is not legal advice. Laws change and differ by place; check the primary sources below.
Quick summary
- The label in a contract does not decide classification. Agencies and courts look at the actual working relationship.
- Different laws use different tests: the FLSA uses an "economic reality" test, the IRS uses a common-law control test, and some states use a stricter "ABC" test.
- The same worker can be an employee under one law and a contractor under another.
- Misclassification can lead to back wages, back taxes, penalties, and lost benefits.
What it means
An employee works in someone else's business under that business's direction. Employers withhold income tax, pay their share of Social Security and Medicare, and must follow wage-and-hour, anti-discrimination, unemployment-insurance, and workers' compensation laws for employees.
An independent contractor is in business for themselves. They control how the work is done, usually serve several clients, bear their own expenses, and can make or lose money. Most employment protections do not apply to them, and they pay self-employment tax.
Because the consequences differ so much, the law looks past what the parties call the relationship and asks how it actually works.
Key terms
- Misclassification
- Treating a worker as an independent contractor when the applicable legal test makes them an employee.
- Economic reality test
- The FLSA test that asks whether the worker is economically dependent on the business or is in business for themselves.
- Common-law control test
- The test used by the IRS and many courts that weighs behavioral control, financial control, and the relationship of the parties.
- ABC test
- A stricter test, used in California and some other states for some purposes, that presumes employment unless all three of its conditions are proved.
- Form SS-8
- An IRS form a worker or business can file to ask the IRS to determine a worker's status for federal tax purposes.
- Self-employment tax
- The Social Security and Medicare tax independent contractors pay on their net earnings, covering both the employer and employee shares.
How the law works
Federal wage law (FLSA): economic reality
The Fair Labor Standards Act defines "employ" very broadly, as to "suffer or permit to work" (29 U.S.C. § 203(g)). Courts and the Department of Labor apply an economic reality test that looks at the whole relationship. The U.S. Department of Labor's 2024 rule (29 C.F.R. part 795) lists six factors:
- the worker's opportunity for profit or loss depending on managerial skill;
- investments by the worker and the business;
- the degree of permanence of the relationship;
- the nature and degree of the business's control;
- whether the work is an integral part of the business;
- the worker's skill and initiative.
No single factor decides the question. The Department of Labor proposed replacing the 2024 rule in February 2026; check the Department's rulemaking page for the current status before relying on the factor list.
Federal tax law (IRS): common-law control
For federal employment taxes, the IRS applies common-law rules that ask whether the business has the right to direct and control how the work is done. The IRS groups the evidence into three categories: behavioral control (instructions, training), financial control (who pays expenses, investment, method of payment, opportunity for profit or loss), and the type of relationship (contracts, benefits, permanence, and whether the work is a key part of the business). A worker or business can ask the IRS for a determination on Form SS-8.
State law: tests vary, and some are stricter
States apply their own tests for state wage laws, unemployment insurance, and workers' compensation. California's Labor Code § 2775 codified an ABC test for many purposes, following the California Supreme Court's decision in Dynamex Operations West, Inc. v. Superior Court (2018). Under an ABC test, a worker is an employee unless the business shows that (A) the worker is free from its control, (B) the work is outside the usual course of its business, and (C) the worker is customarily engaged in an independently established trade or business. California's statute has many exemptions. Other states use ABC tests for unemployment insurance or other limited purposes.
Consequences of misclassification
Depending on the law involved, misclassification can expose a business to unpaid minimum wage and overtime, liquidated damages under the FLSA (29 U.S.C. § 216(b)), unpaid employment taxes and penalties, unemployment-insurance and workers' compensation assessments, and state-law penalties. For workers, being treated as a contractor can mean losing overtime, unemployment eligibility, and employer tax contributions.
Examples
Hypothetical example
A freelance designer with many clients
A graphic designer sets her own hours, uses her own software, invoices several companies, and markets her services publicly. These facts point toward independent contractor status under most tests, though the contract terms and any state ABC test would still matter.
Hypothetical example
A "contractor" who works like staff
A delivery company calls its drivers contractors, but sets their schedules, requires company uniforms, pays by the hour, and drivers have worked only for the company for years. Facts like these are the kind agencies and courts weigh toward employee status, because the work is central to the business and the company controls how it is done.
Common questions
Does signing an independent contractor agreement make someone a contractor?
No. Courts and agencies look at the actual relationship. A written agreement is evidence of how the parties intended to work together, but it does not override the applicable legal test.
Is there one test that applies everywhere in the United States?
No. Federal wage law, federal tax law, and state laws each use their own test. The same worker can be classified differently under different laws.
Who decides classification for tax purposes?
The IRS can make a determination for federal tax purposes if a worker or business files Form SS-8. State tax and labor agencies make their own determinations under state law.
Can a worker be paid on a 1099 and still be owed overtime?
The tax form used does not decide FLSA coverage. If the economic reality test makes the worker an employee under the FLSA, overtime rules can apply regardless of the form used to report pay.
Important distinctions
Independent contractor vs. employee vs. temp worker
A worker placed by a staffing agency is usually the agency's employee, and the business that uses their services may also be treated as a joint employer under some laws. That is a different question from contractor classification.
Tax classification vs. wage-law classification
The IRS control test and the FLSA economic reality test overlap but are not the same. A determination under one does not automatically settle the other.
