W-2 vs. 1099: How to Classify Workers (and Why It Matters)

As your business grows and you bring on help, one of the first big questions is: are they an employee (W-2) or an independent contractor (1099)? Get it wrong and the penalties can be steep — so let's make it clear.

The core difference: control

The IRS looks at how much control you have over the worker, across three areas:

  • Behavioral control — Do you direct how, when, and where the work is done, or just the end result? Detailed direction points toward employee.
  • Financial control — Who controls the business side? Contractors typically have their own tools, can work for others, and can make a profit or loss.
  • Relationship — Is it ongoing and central to your business with benefits, or project-based and independent?

Why it matters so much

For employees, you withhold income tax, pay half of their Social Security and Medicare, and may owe unemployment tax. For contractors, you generally just issue a 1099-NEC. Treating an employee like a contractor to skip those obligations is the kind of thing that triggers back taxes, interest, and penalties if you're caught.

When it's genuinely unclear, you can ask the IRS to make the determination using Form SS-8 — but it's usually faster to talk it through with us first.

Don't forget the paperwork

  • New employees: collect a Form W-4 and verify eligibility with Form I-9.
  • New contractors: collect a Form W-9 before you pay them, so 1099s are easy at year-end.
