1099 or W-2? What Actually Makes Someone an Employee vs. an Independent Contractor
You don't get to decide whether someone is a 1099 contractor or a W-2 employee just because it's easier or cheaper for your business. The IRS determines it by looking at the actual working relationship: who controls the work, who bears the financial risk, and how permanent the arrangement is. Get it wrong, and the label on the paperwork won't protect you.
The Three Things That Actually Decide It
The IRS calls this the common law test, and it weighs three categories of facts. No single factor makes the decision by itself, a similar fact pattern can point different directions depending on the rest of the relationship.
Behavioral control. Do you control, or have the right to control, what the worker does and how they do it? Setting hours, dictating methods, requiring specific training, or supervising the process (not just reviewing the finished result) all point toward employee status.
Financial control. Are the business aspects of the job controlled by you, the payer? This includes how the worker is paid, whether you reimburse their expenses, and who supplies the tools and equipment. A worker with real unreimbursed expenses and their own equipment looks more like an independent business.
Type of relationship. Is there a written contract? Do they get anything resembling employee benefits, like insurance or paid time off? Is the relationship ongoing and indefinite, or tied to a specific project with an end date? Is the work a key part of what your business does, or incidental to it?
The IRS is explicit that there's no magic number of factors and no single one that settles it. You look at the entire relationship and document how you got to your conclusion.
Remote work doesn't change the analysis
A worker performing services from home instead of your office is still your employee under these same rules if you control what gets done and how. Letting someone work remotely is a business decision, but it doesn't change the analysis.
2. What Changes Once You Know Which One Applies
Payroll taxes work in opposite directions
For an employee, you withhold income tax and the employee's share of Social Security and Medicare (7.65%) from every paycheck. You separately pay the matching 7.65% employer share, plus federal and state unemployment tax. For an independent contractor, generally none of that applies. You don't withhold anything, and the contractor is responsible for the full 15.3% self-employment tax themselves.
Contractors run their own business, with the trade-offs that come with it
An independent contractor isn't covered by minimum wage or overtime rules, doesn't get unemployment insurance if the relationship ends, and isn't covered by your workers' compensation policy. In exchange, they can generally deduct legitimate business expenses (equipment, mileage, home office costs) against their income. A W-2 employee generally can't deduct unreimbursed work expenses at all under current law. Neither classification is simply "better." They're two different sets of obligations and protections.
3. Getting It Wrong Is More Expensive Than Getting It Right
The consequences aren't hypothetical
If you classify a worker as a contractor without a reasonable basis for doing so, you can be held liable for the employment taxes you should have withheld and paid, on top of penalties. There's a narrow relief provision if you had a reasonable basis for the classification and you've been consistent about it, but it's not automatic, and it doesn't retroactively make the classification correct. It only limits your tax exposure.
If you're genuinely unsure
The IRS lets either the business or the worker file Form SS-8 to request an official determination. It's slow (expect at least six months for an answer), so it's a tool if you're genuinely unsure. There's also a Voluntary Classification Settlement Program that lets a business proactively reclassify workers as employees going forward, with partial relief from past federal employment tax exposure, for those who qualify.
Keep It Simple / Key Takeaway 🍕
Ask yourself honestly: if you handed this person the exact same work but called them an employee tomorrow, would anything about how the job actually gets done change? If the answer is no, the relationship was probably already an employee relationship. The invoice just hadn't caught up to it yet.
