Contractor or employee? How the IRS looks at the relationship

Tax-year note: Tax information on this page applies to the 2026 tax year (returns filed in 2027), from IRS pages checked in November 2026. Figures and dates are labelled with their tax year where they appear. Check current IRS pages before you rely on them.

Being self-employed rests on a premise: you are in business for yourself, not an employee of your client. That premise matters for taxes, benefits and legal protections. The IRS uses a facts-and-circumstances approach to decide it, and other agencies, including the Department of Labor and state agencies, may apply their own tests for their own laws. This guide covers the IRS approach only.

Why it matters

The IRS explains that for employees, a business generally must withhold income tax, Social Security and Medicare taxes, pay the matching employer share, and pay unemployment tax. Generally a business does not withhold or pay any of those taxes on payments to independent contractors. For a contractor, that means you handle your own tax payments; see self-employment tax explained and the estimated tax calendar.

The IRS also says, simply, that if you are a business owner or contractor providing services to other businesses, you are generally considered self-employed.

The three categories of evidence

The IRS says all information that provides evidence of the degree of control and independence must be considered, and groups it into three categories:

1. Behavioral. Does the company control, or have the right to control, what the worker does and how the worker does the job?
2. Financial. Are the business aspects of the job controlled by the payer? The IRS gives examples such as how the worker is paid, whether expenses are reimbursed, and who provides tools and supplies.
3. Type of relationship. Are there written contracts or employee-type benefits, such as a pension plan, insurance or vacation pay? Will the relationship continue, and is the work a key aspect of the business?

The IRS stresses there is no magic or set number of factors, and no one factor stands alone. The key is the entire relationship and the extent of the right to direct and control the worker.

Remote work does not decide it

A common assumption is that working from home makes you a contractor. The IRS addresses this directly: a person working remotely is an employee under the common-law rules if the business can control what will be done and how it will be done, even if the worker can choose to work remotely. What matters is the right to control the details.

Signs worth noticing as a worker

These are not tests, just prompts to look at the relationship honestly:

• Are you told what hours to work and how to do each task?
• Are you trained in the client's methods?
• Are you paid by the hour with expenses reimbursed, or by project with your own costs?
• Do you use your own equipment?
• Do you have other clients, or could you?
• Is the arrangement open-ended, with benefits-like terms?

If the arrangement looks like a job with a contractor label, read the IRS page carefully.

Form SS-8

When status is unclear, the IRS says a business or a worker may file Form SS-8, Determination of Worker Status. The IRS reviews the facts and officially determines status. It notes that a determination may take at least six months.

The IRS also describes Form 8919, which workers who believe they were improperly classified can use to figure and report the employee share of uncollected Social Security and Medicare taxes on their compensation.

When you are the one hiring

As your business grows you may hire help. The same tests then apply in the other direction. The IRS says a business owner hiring individuals must determine whether they are employees or contractors, and should document each factor used in reaching the decision. It warns that a business that classifies an employee as a contractor without a reasonable basis may be held liable for employment taxes.

For contractors, the IRS page on forms and associated taxes explains information returns such as Form 1099-NEC. Thresholds for those returns are set per tax year and have changed; check the current IRS instructions for the tax year in question before relying on any amount.

A plain record for each client

Keep a short note per client: what you deliver, who sets the method and schedule, how you are paid, what equipment you use, and how long the work runs. It takes minutes and gives you a clear picture if the question ever comes up.
