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?

1 Does the company provide detailed instructions on when, where, and how to perform the work?

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.

2 Does the company provide training to the worker on how to do the job?

Training on required procedures or methods signals an employment relationship. Independent contractors are expected to already possess the skills and expertise for the job.

3 Does the company evaluate the worker’s performance beyond measuring the end result?

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.

4 Does the company set the worker’s schedule or required hours?

Setting specific work hours or days of attendance is a hallmark of employee status. Independent contractors generally control their own schedules.

5 Does the company dictate the order or sequence in which the work must be performed?

Controlling the sequence of tasks limits the worker’s autonomy and points toward employee status. Contractors typically decide their own workflow and priorities.

6 Does the company require the worker to personally perform the services (cannot subcontract or delegate)?

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.

7 Does the company provide tools, equipment, or supplies for the 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?

8 Does the company control how the worker is paid (e.g., hourly wage or salary versus flat project fee)?

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.

9 Does the company reimburse the worker’s business or travel expenses?

Reimbursing expenses is more typical of an employment relationship. Independent contractors typically absorb their own business expenses and factor those costs into their pricing.

10 Does the worker have a significant investment in their own equipment, facilities, or tools?

A significant unreimbursed investment in facilities or equipment suggests the worker is an independent contractor running their own business operation.

11 Can the worker realize a profit or suffer a loss from their services?

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.

12 Does the worker offer their services to the general public or other businesses?

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.

13 Is the worker free to seek out and accept other business opportunities while engaged with your company?

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?

14 Is there a written contract that describes the relationship?

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.

15 Does the company provide employee-type benefits (health insurance, pension plan, paid vacation, sick pay)?

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.

16 Is the relationship expected to continue indefinitely rather than for a specific project or period?

An indefinite relationship suggests employee status. Independent contractor arrangements typically have a defined scope and end point, even if they are renewed periodically.

17 Are the worker’s services a key aspect of the company’s regular business operations?

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.

18 Can either party terminate the relationship at any time without incurring liability or penalty?

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.

19 Does the worker perform services exclusively for your company (not working for others simultaneously)?

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.

20 Does the worker report to a manager or supervisor within the company on a regular basis?

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.

Misclassification Risk Assessment

If the classification is incorrect, here is the potential exposure for your organization.

Penalty Exposure Calculator

Enter the worker’s annual wages to see your potential penalty exposure under IRS Section 3509 and related provisions.

$

Section 3509 Penalties (1099 Filed)

IRC § 3509(a) — Reduced Rates
If you filed a Form 1099-NEC for the misclassified worker, reduced penalty rates apply: 1.5% of wages for federal income tax withholding liability plus 20% of the employee’s share of FICA (Social Security & Medicare taxes).
Enter wages above

Section 3509 Penalties (No 1099 Filed)

IRC § 3509(b) — Doubled Rates
If no Form 1099-NEC was filed for the worker, penalty rates double: 3% of wages for federal income tax withholding plus 40% of the employee’s share of FICA. This significantly increases your exposure.

Willful Misclassification

Full Tax Liability + Penalties + Interest
If the IRS determines misclassification was willful (intentional), Section 3509 reduced rates do not apply. The employer owes 100% of all unpaid employment taxes, plus failure-to-withhold penalties, failure-to-deposit penalties, and accrued interest.
Enter wages above

Trust Fund Recovery Penalty (TFRP)

IRC § 6672 — Personal Liability
The TFRP equals 100% of unpaid trust fund taxes (employee portion of FICA plus withheld income tax). Critically, this penalty is assessed personally against responsible individuals — officers, directors, or anyone with authority over financial decisions — and cannot be discharged in bankruptcy.
Enter wages above
⚠ State-Level Penalties: In addition to federal penalties above, most states impose their own penalties for worker misclassification. These may include state unemployment tax (SUI/SUTA) assessments, state income tax withholding penalties, workers’ compensation premium adjustments and fines, and additional state-specific civil or criminal penalties. Several states — including California, Massachusetts, New York, New Jersey, and Illinois — have enacted particularly aggressive misclassification enforcement statutes with penalties reaching $25,000+ per violation. Contact a qualified employment tax professional for a state-specific analysis.
