You’ve got a guy. He shows up most weeks, does great work, and you pay him at the end of the job. Easy — you hand him a 1099 at tax time and move on.
Except the IRS might not see it that way. And if they don’t, “easy” turns into back payroll taxes, penalties, and interest — for every year you got it wrong.
Here’s the thing most contractors don’t realize: you don’t get to decide whether someone is a 1099 contractor or an employee just by calling them one. The IRS looks at the actual working relationship, not the label on the paperwork.
What the IRS actually looks at
There are three buckets they weigh:
Behavioral control. Do you tell them exactly how, when, and where to do the work — or do they run their own show? The more you’re directing the specific methods, the more it looks like employment.
Financial control. Do they show up with their own tools and take on other clients, or are they using your equipment and working exclusively for you? Real independent contractors usually have skin in the game — their own investment, their own risk.
Type of relationship. Is this tied to a specific job with a clear end, or has it quietly become an ongoing, indefinite arrangement that’s just… part of how your business runs now? That second one is a red flag.
Why this sneaks up on people
Nobody sets out to misclassify anyone. It usually happens gradually — a subcontractor you hired for one job just kept coming back, month after month, year after year, until one day they’re basically running your framing crew and you’re still handing them a 1099 like it’s 2019.
That gradual drift is exactly where the risk lives. The relationship changed. The paperwork didn’t.
What’s actually at stake
If the IRS (or your state’s labor department) decides someone you’ve been treating as a 1099 was really an employee, you’re on the hook for the employer’s share of Social Security and Medicare taxes you didn’t withhold, plus penalties and interest — going back as far as they want to look. For a crew of even two or three misclassified workers, that number gets uncomfortable fast.
What to actually do about it
This isn’t about panicking and converting everyone to W-2 tomorrow. It’s about actually knowing where you stand. If someone’s genuinely running their own business — their own tools, their own clients, paid per job — you’re probably fine. If the relationship has drifted toward “this person is basically part of my team now,” that’s worth a real conversation before it’s a real problem.
