Employee or Independent Contractor? The IRS Test, Form SS-8 and the Labor Department's Separate Rule

How we wrote this: A summary of the IRS's "Independent contractor (self-employed) or employee?" and Form SS-8 pages and the U.S. Department of Labor's misclassification and rulemaking pages (linked below), checked October 29, 2026. This is general information, not legal or tax advice. State rules can differ and aren't covered here.

Before you pay someone for work, you have to decide what they are. The IRS puts it plainly: it's critical to get this right. Employees mean withholding income tax, withholding and matching Social Security and Medicare, and paying unemployment tax. Independent contractors generally mean none of those, just a W-9 and possibly a 1099-NEC.

The label you choose, or what the contract says, doesn't decide it. The actual relationship does.

The IRS test: who controls the work?

The IRS uses common-law rules. All evidence of control and independence counts, and it falls into three groups:

Category	The question	Examples of what's weighed
Behavioral	Does the business control, or have the right to control, what the worker does and how they do it?	Instructions, training, how the work is done
Financial	Does the business control the business side of the job?	How the worker is paid, whether expenses are reimbursed, who provides tools and supplies
Type of relationship	How do the parties see the arrangement?	Written contracts, employee-type benefits (pension, insurance, vacation pay), whether it's ongoing, and whether the work is a key part of the business

The IRS stresses there's no magic number of factors. Some may point one way and some the other, no single factor decides it, and a factor that matters in one case may be irrelevant in another. Look at the whole relationship, focus on the right to direct and control, and write down how you reached your decision.

Remote workers aren't automatically contractors

A common assumption is that someone working from home must be a contractor. The IRS says otherwise: a remote worker is your employee under the common-law rules if you can control what will be done and how, even if the worker chose to work remotely. What matters is your right to control the details.

Still unsure? Form SS-8

If you can't tell, or you regularly hire the same kind of worker, you can ask the IRS to decide with Form SS-8, Determination of Worker Status. Either the business or the worker can file it. The IRS reviews the facts and makes an official determination, but warns it may take at least six months.

What misclassification costs

If you treat an employee as a contractor with no reasonable basis, the IRS says you can be held liable for that worker's employment taxes.

There are two ways out the IRS describes:

Section 530 relief. If you had a reasonable basis for not treating the worker as an employee, filed all required information returns (such as 1099s) consistently with that treatment, and haven't treated anyone in a substantially similar position as an employee for periods after 1977, you may be relieved of the employment taxes. This doesn't make the worker a contractor; it only limits your tax liability. Details are in Publication 1976.
Voluntary Classification Settlement Program (VCSP). Eligible businesses can agree to treat workers as employees going forward and get partial relief from past federal employment taxes, by filing Form 8952.

On the worker's side, someone who believes they were wrongly treated as a contractor can file Form 8919 with their tax return to report their share of uncollected Social Security and Medicare tax.

The Labor Department uses a different test

Federal tax law isn't the only rule. Under the Fair Labor Standards Act (FLSA), employees are owed minimum wage and overtime, and contractors aren't. The Department of Labor says employers are responsible for determining status and calls misclassification "a serious problem."

The FLSA test looks at the economic realities of the relationship: whether the worker is economically dependent on the employer or truly in business for themselves. The DOL's rules here are in flux:

A 2024 rule (effective March 11, 2024) set out a six-factor "economic reality" analysis. The DOL's Fact Sheet 13 notes that rule is the subject of litigation, remains in effect for private lawsuits, and points to Field Assistance Bulletin 2025-1 (May 1, 2025) for the Wage and Hour Division's current enforcement position.
On February 26, 2026, the DOL announced a proposed rule on employee or independent contractor status under the FLSA, the Family and Medical Leave Act and the farmworker protection law. Comments closed April 28, 2026. As of the DOL page we checked, it was still a proposal.

So a worker could, in principle, be treated one way for federal tax and need a separate look for wage-and-hour law. Check the DOL misclassification page for the latest, and your state's rules too.

A practical checklist before you hire

Write down how you'll control the work: schedule, methods, tools, training.
Note who pays expenses and supplies equipment, and whether the worker can profit or lose money.
Decide whether the role is ongoing and core to your business.
Record your reasoning; the IRS tells businesses to document the factors.
If the answer is "employee," follow our hiring your first employee guide.
If "contractor," collect a W-9 before the first payment.
If it's genuinely unclear, consider Form SS-8 or a professional's advice.
