The IRS groups common-law evidence into three categories

For federal employment-tax purposes, the IRS asks whether the business has the right to direct and control the worker. Its current small-business guidance organizes relevant facts into three categories: behavioral control, financial control, and the type of relationship. The categories are not three votes, and there is no rule that two out of three automatically produces an answer.

A useful review therefore starts with evidence, not adjectives. “Independent,” “flexible,” and “project based” mean little unless the business can show how the work is actually performed and paid.

Behavioral control: who controls the method?

Behavioral control covers instructions, training, and other facts showing whether the business directs how the worker does the job.

Document whether the business tells the worker when and where to work, what tools or equipment to use, which workers to hire or assist with the work, where to buy supplies or services, what sequence or order to follow, or how the result must be produced. The IRS notes that the amount of instruction needed can vary by occupation; a highly skilled person may need little day-to-day instruction while the business still retains the right to control the work.

Training is another signal. Periodic or ongoing instruction about required procedures can indicate that the business expects the work to be performed in a particular way. By contrast, specifying a deliverable, safety requirement, customer constraint, or completion date does not by itself answer whether the business controls the method.

Pull evidence from onboarding messages, operating manuals, calendars, task software, quality-review notes, training records, and manager communications. The question is what rights the company possesses, not merely whether a manager exercised every right every day.

Financial control: is this genuinely a separate business?

Financial control looks at the economic aspects of the activity.

Record the worker’s unreimbursed business expenses, investment in tools or facilities, ability to make services available to other customers, method of payment, and opportunity for profit or loss. A worker who prices projects, controls significant costs, invests in business assets, advertises to the public, and can lose money through poor business decisions looks different from somebody who supplies labor for a fixed wage using the company’s resources.

Do not overread one fact. Employees can have unreimbursed expenses; contractors can be paid hourly; some occupations require little capital. The IRS says all relevant facts must be weighed.

For a real review, compare the invoice terms to the financial reality. Who absorbs rework? Who pays assistants? Who buys software? Does the worker negotiate rates? Can the worker increase profit by managing costs or serving several clients? Those questions reveal more than the word “invoice.”

Type of relationship: what have the parties built?

The third category examines how the parties perceive and structure the relationship. Written contracts can matter, as can employee-type benefits such as insurance, pension plans, paid leave, or vacation pay. Permanency matters too: an indefinite relationship may point differently from a project with a defined end.

The IRS also considers whether the services are a key activity of the business. A company is more likely to have the right to direct and control work that is central to its regular operations, although this fact still belongs in the overall analysis.

Read the contractor agreement alongside offer emails, benefit eligibility, renewal history, termination provisions, job descriptions, organization charts, and the way the worker is presented to customers. If the contract says “independent” but the worker is managed exactly like staff, note the inconsistency rather than hiding it.

Build an evidence worksheet, not a scorecard

Use three columns headed Behavioral, Financial, and Relationship. Under each, record facts that point toward employee status, facts that point toward an independent business, and the document supporting each fact. Add a final column explaining why a fact matters.

For example, “Worker chooses which days to perform the project” belongs under behavioral control; “Worker pays for specialized equipment and bears repair costs” belongs under financial control; “Six-month contract for a discrete migration project” belongs under relationship. A statement such as “factor favors contractor” without supporting detail is much weaker.

Do not assign one point per item. The old Revenue Ruling 87-41 listed twenty factors, but current IRS materials emphasize the three broader categories and the totality of the relationship. Some facts carry more significance in one occupation than another.

Keep other legal tests separate

The IRS framework is for federal employment-tax classification. It is not a universal test for every labor law. The Department of Labor uses an economic-reality analysis under the FLSA, and states can impose ABC tests or other standards.

This distinction matters when someone says, “Our accountant says the contractor is fine.” That may address a tax position but not wage-and-hour, unemployment, workers’ compensation, or state-law exposure. Identify the legal question first, then apply the framework that governs it.

If the federal tax answer remains uncertain after documenting the real facts, Form SS-8 is the IRS process for requesting a worker-status determination. Do not send the form expecting an immediate answer; IRS guidance says the determination process can take at least six months.
