A 1099 worker is an independent contractor paid through IRS Form 1099-NEC, named for the tax form the client issues to report what it paid them. Unlike a W-2 employee, a 1099 worker has no income tax withheld, receives no employer-paid payroll taxes and no benefits, and is responsible for paying self-employment tax and managing their own tax obligations. The client engages the contractor for a defined scope of work rather than employing them, which means the worker typically controls how and when the work gets done. Whether someone can legitimately be treated as a 1099 worker is a worker-classification question decided by IRS and state-level tests, not by the label on the contract. Using a 1099 arrangement for someone who actually functions as an employee is misclassification, and it carries significant back-tax, penalty, and legal exposure for the client.
The term "1099 worker" comes directly from the tax form. When a US business pays an independent contractor $600 or more in a year, it reports those payments on IRS Form 1099-NEC (Nonemployee Compensation). That single form captures the core of the relationship: the business pays the contractor a gross amount and withholds nothing.
What the client does and does not do
Because of this, hiring a independent contractor on a 1099 basis is administratively lighter and cheaper for the client, which is exactly why the classification is scrutinized so closely by regulators.
The clearest way to understand a 1099 worker is to compare it with a W-2 employee. The two classifications determine who bears the tax burden, who controls the work, and what protections apply.
| Feature | 1099 Worker | W-2 Employee |
|---|---|---|
| Tax form | Form 1099-NEC | Form W-2 |
| Tax withholding | None — worker self-remits | Withheld by employer |
| Payroll taxes (FICA) | Worker pays both halves (self-employment tax) | Employer pays its share |
| Benefits | None from client | Employer-provided |
| Labor protections | Generally none | Minimum wage, overtime, etc. |
| Control over work | Worker controls how and when | Employer directs the work |
The label a business chooses does not settle the question. What matters is the actual working relationship, measured against the classification tests below.

Book a Demo Whether a worker can legitimately be paid on a 1099 is not the client's choice — it is a legal determination made against established tests. Applying the 1099 label to someone who functions as an employee is worker misclassification.
The main tests
Getting this wrong is expensive. A business that misclassifies an employee as a 1099 worker can owe back payroll taxes, unpaid overtime and minimum wage, penalties, interest, and benefits — plus exposure to state audits and worker lawsuits. Because state tests vary and are often stricter than the federal standard, classification must be assessed jurisdiction by jurisdiction, which is why workforce compliance is central to any 1099 program.
WorkGenius removes the classification guesswork from engaging 1099 talent. We assess worker classification before every engagement, applying the relevant IRS and state tests so you know whether a worker should be a 1099 contractor or belongs on a compliant payroll instead.
When a role calls for employment rather than a contractor arrangement, WorkGenius acts as Employer of Record across all 50 US states and 100+ countries — taking on the legal employment, withholding, and benefits so you stay compliant without setting up entities yourself. And when a true 1099 engagement is appropriate, our platform handles onboarding, contracts, and payment in one place. Combining AI matching with expert human recruiters, WorkGenius gives you a single system to source, classify, onboard, manage, and pay contingent workers — with compliance built in from the first engagement.
It means you are an independent contractor, not an employee. You receive your full pay with no taxes withheld, get no benefits or employer payroll-tax contributions, and are responsible for paying your own income and self-employment taxes. The "1099" refers to IRS Form 1099-NEC, which the client issues to report what it paid you.
The 1099 worker does. Because the client withholds nothing, the contractor must calculate and remit their own income tax and pay self-employment tax, which covers both the employee and employer shares of Social Security and Medicare. Many 1099 workers make quarterly estimated tax payments to stay current.
A W-2 employee has taxes withheld by the employer, receives employer-paid FICA, benefits, and labor protections, and works under the employer's direction. A W-2 employee is on payroll, while a 1099 worker is a self-employed contractor who manages their own taxes and controls how the work gets done.
It becomes misclassification when someone is paid on a 1099 but actually functions like an employee — for example, working set hours under close direction with ongoing dependence on one client. Classification is judged by the IRS common law test and stricter state tests like the ABC test, not by the contract label, and getting it wrong can trigger back taxes and penalties.
In practice they overlap heavily. "Freelancer" describes the working style, while "1099 worker" describes the US tax classification used to pay an independent contractor. Most US-based freelancers and contingent professionals are paid on a 1099 basis when they qualify as genuinely independent.
