Do 1099 Employees Need to Fill Out an I-9?

A person who is genuinely an independent contractor does not need to complete Form I-9 for that contract engagement. Form I-9 is required when an employer hires someone as an employee to perform work in the United States for wages or other remuneration. The label “1099 employee” does not determine the answer because “1099” refers to tax reporting, not a worker’s legal classification. If the working relationship is actually an employment relationship, the employer must treat the person as an employee for I-9 purposes even if the contract or payment records call them a contractor. The practical question is therefore how the work is structured and directed, not simply which tax form is used.

When Form I-9 Applies

Employers use Form I-9 to verify the identity and employment authorization of people they hire as employees. It is an employee onboarding requirement, not a standard form for every vendor, freelancer, consultant, or service provider.

The USCIS guidance on who completes Form I-9 explains that self-employed individuals generally do not complete the form for themselves. An exception may apply when a person is an employee of a separate business entity, such as a corporation or partnership. In that situation, the entity may have to complete Form I-9 for the person’s employee role.

Why the 1099 Label Can Mislead

“1099 employee” is a common phrase, but it combines two different categories. A worker is generally an employee or an independent contractor; the “1099” label refers to tax reporting for certain payments and does not create a separate worker status.

USCIS states that an independent contractor is not considered an employee for Form I-9 purposes. Its I-9 exceptions guidance describes contractors as individuals or entities that operate an independent business and undertake work using their own means and methods. The contracting organization generally controls the result rather than how the work is performed.

How to Assess the Working Relationship

The I-9 answer depends on the actual relationship, not only the written contract or payment system. A contractor relationship commonly involves a person who runs an independent business, controls how the work is performed, and agrees to provide a particular service or outcome. The person may use their own tools and methods and have meaningful independence over schedule and process.

By contrast, a business may be treating someone as an employee when it directs the person’s day-to-day work, schedule, and methods. A client can specify the result it needs from a contractor, such as a finished website or marketing plan. Directing the daily steps in the same way it directs employees may raise questions about whether the person is properly classified.

These are useful factors for understanding the distinction, but no single label or detail settles every classification question. The relationship as a whole matters. The same person can be a contractor in one engagement and an employee in another.

What Paperwork Should Each Worker Complete?

Employees generally complete Form I-9 as part of onboarding and provide the tax information needed for payroll. Contractors usually provide a Form W-9 so the business can handle applicable tax reporting. The parties may also use a services agreement or statement of work that describes the services and deliverables. A contractor’s paperwork does not include Form I-9 solely because the person is providing services to a business.

Using contractor paperwork does not make an employment relationship a contractor relationship. If a person is treated as a contractor on paper but is controlled like an employee in practice, the mismatch can raise classification issues involving taxes, benefits, and labor protections. The National Employment Law Project likewise explains that employers are not required to verify independent contractors through Form I-9 in its FAQs for immigrant workers and advocates.

Does E-Verify Apply to Contractors?

E-Verify is an electronic system some employers use to confirm employment eligibility for employees after completing the Form I-9 process. It is separate from Form I-9 and does not make contractors subject to employee verification requirements simply because a business uses the system for its employees.

The Department of Homeland Security’s E-Verify guidance for independent contractors explains that the rules use common-law understandings of the employer-employee relationship to determine who is an independent contractor. In general, employers are not required to complete Form I-9 or use E-Verify for a genuine independent contractor.

When a Contractor May Need Form I-9

A person who works as a contractor for one organization may still need Form I-9 in a separate employee role. For example, a self-employed consultant generally does not complete an I-9 for their own consulting work. If a separate corporation or partnership hires that person as an employee, the entity may have to complete Form I-9 for that employment. The relevant question is whether the person is an employee in that particular relationship.

USCIS addresses this distinction in its guidance on who must complete Form I-9. A person’s contractor status in one engagement does not determine their status in every other role.

Before Onboarding a Worker

First, identify whether the engagement is an employee role or an independent service arrangement. Consider how much control the organization will have over the details of the work, rather than relying only on the contract’s title. Then use paperwork that fits the relationship: Form I-9 for employees, and contractor documentation such as a W-9 and services agreement for independent contractors. A well-organized onboarding process can help keep employee verification records distinct from contractor agreements and invoices.

If the actual working arrangement does not match the contractor label, changing the paperwork alone does not resolve the mismatch. The classification should reflect how the work is performed and managed.
