Worker misclassification is one of those issues where a lot of guys in the trades are doing it wrong and don't know it. Not out of dishonesty — they just never learned the actual rules, and calling someone a 1099 when they're really an employee feels simpler and cheaper. It is simpler. Until the IRS or your state labor board gets involved.

Let me break down how this actually works and where the real line is.

Why it matters

When you classify someone as an independent contractor (1099), you're saying they're running their own business and working for you as a client. You don't withhold taxes. You don't pay payroll taxes. You don't pay workers' comp on them. You don't give them overtime. You pay them their rate and send a 1099 at year end.

When someone is a W-2 employee, you pay employer payroll taxes (7.65% of their wages), withhold their income taxes, pay workers' comp on them, and follow federal and state labor law regarding overtime, breaks, and working conditions.

The difference in cost to you is significant — roughly 20–30% more to employ someone properly versus treating them as a 1099. That's the financial incentive that leads a lot of small contractors to misclassify. But the risk when you get it wrong is much larger than the savings.

What the IRS actually looks at

The IRS uses a multi-factor test, but it comes down to three main questions about behavioral control, financial control, and the nature of the relationship.

Behavioral control: Do you control how they do their work? If you're telling someone what time to show up, how to do the job, what equipment to use, and supervising them throughout the day — that looks like employment, not contracting.

Financial control: Do they work for multiple clients? Do they have their own tools and equipment? Do they have a real opportunity for profit or loss on the work? If someone works exclusively for you, uses your equipment, and gets paid by the hour with no real business risk — they're probably an employee.

Type of relationship: Is the relationship ongoing and indefinite? Is the work they're doing central to your business operations? An excavation crew member who works for you every week running your equipment is almost certainly an employee by this standard.

A legitimate 1099 subcontractor, by contrast, typically has their own license, carries their own insurance, works for multiple general contractors, quotes the job at a flat price, uses their own equipment, and has real business risk if the job goes over budget.

The most common mistake

The most common misclassification I see in contracting is a day laborer or regular crew member being paid cash or check with no withholding, given a 1099 at year end, and called an independent contractor. If that person works exclusively or primarily for you, uses your equipment, and is told when and how to do the work — they're an employee by the IRS definition, regardless of what you call them or what they agreed to.

The fact that they agreed to be a 1099 doesn't actually matter legally. The classification test is about the economic reality of the relationship, not what the parties called it.

What happens if you get it wrong

The penalties for misclassification are real and stack up fast. If the IRS determines someone you classified as a 1099 was actually an employee, you can owe back payroll taxes for all unpaid quarters, plus interest and penalties. State labor boards can add additional fines. And if the worker was injured and you didn't have workers' comp coverage on them as required — now you're also looking at an uninsured employer situation.

None of these outcomes are worth the payroll tax savings.

My honest take

When in doubt, classify as W-2. The cost difference is real, but so is the risk. If you're working with legitimate subs who have their own license, their own insurance, their own equipment, and their own client base — 1099 is appropriate. If someone is working alongside your crew every week using your equipment and showing up when you tell them to — set them up as an employee and do it right.
