Worker Classification Tool
Determine proper worker classification using the IRS three-factor test. Assess whether a worker should be classified as a W-2 Employee or 1099 Independent Contractor.
Is Your Worker an Employee or Independent Contractor?
The IRS uses a three-factor framework derived from common law to evaluate worker classification. Misclassification can result in severe penalties, back taxes, and interest. This tool walks you through each factor to provide an informed assessment.
Behavioral Control
Does the company control how and when the work is performed?
Financial Control
Does the company control the business aspects of the worker's role?
Type of Relationship
What is the nature and permanency of the working arrangement?
This assessment consists of 20 questions across three categories and takes approximately 5–8 minutes to complete.
Behavioral Control
Does the company control or have the right to control what the worker does and how they do it?
Providing specific instructions — such as what tools to use, where to purchase supplies, the order of tasks, or when to report — indicates the worker is an employee. Contractors typically set their own methods.
Training on required procedures or methods signals an employment relationship. Independent contractors are expected to already possess the skills and expertise for the job.
If the company evaluates how the work is done — not just whether the result meets expectations — that level of oversight is characteristic of an employer-employee relationship.
Setting specific work hours or days of attendance is a hallmark of employee status. Independent contractors generally control their own schedules.
Controlling the sequence of tasks limits the worker’s autonomy and points toward employee status. Contractors typically decide their own workflow and priorities.
Requiring personal performance suggests the company is interested in the individual specifically — a characteristic of employment. Contractors often have the right to hire helpers or subcontract portions of work.
When the company furnishes tools, materials, or equipment, it indicates a higher degree of control. Independent contractors typically invest in and provide their own tools of the trade.
Financial Control
Does the company control the business aspects of the worker’s job?
Hourly or salary payment suggests an employee relationship. Contractors are typically paid a flat fee per project, upon delivery of a result. Guaranteed regular wages reduce the worker’s financial risk.
Reimbursing expenses is more typical of an employment relationship. Independent contractors typically absorb their own business expenses and factor those costs into their pricing.
A significant unreimbursed investment in facilities or equipment suggests the worker is an independent contractor running their own business operation.
The opportunity for profit or loss is one of the strongest indicators of independent contractor status. Employees generally receive guaranteed compensation regardless of business outcomes.
A worker who markets and provides services to the public at large is more likely to be an independent contractor. Exclusivity to one company suggests employee status.
Freedom to pursue other clients and projects is a strong indicator of contractor status. Restrictions on outside work suggest the company views the worker as an employee.
Type of Relationship
What is the nature, permanency, and formality of the working arrangement?
While a contract alone does not determine status, its terms can reflect the parties’ intent. Contracts labeling a worker as an independent contractor are considered, but are not dispositive — the IRS looks at the actual working arrangement.
Providing employee-type benefits is strong evidence of an employment relationship. Independent contractors typically receive no benefits and must secure their own insurance and retirement plans.
An indefinite relationship suggests employee status. Independent contractor arrangements typically have a defined scope and end point, even if they are renewed periodically.
If the worker performs services that are integral to the company’s core business (not peripheral tasks), the company is more likely to exert behavioral and financial control, suggesting employee status.
The ability to fire the worker at will (or for the worker to quit without consequence) indicates an employment relationship. Contractors often have completion commitments and termination clauses with financial consequences.
Working exclusively for one company is a strong indicator of employee status. Independent contractors typically serve multiple clients and maintain their own book of business.
Regular reporting to management is an indicator of an employment relationship and reflects the company’s right to direct the worker. Contractors typically communicate on deliverables only, without oversight of day-to-day activities.
