W-2 or 1099: The Real Risk Behind Paying Trades Direct
A GC asks to pay a tradesperson direct as a 1099 to skip the markup. Here's why that request quietly converts a staffing relationship into an employment relationship you didn't sign up for.
Contractors & GCs7 min read
A skilled tradesperson can only legally work as a 1099 contractor if they control their own schedule, tools, and work method and serve multiple clients. If a GC directs the work like an employee, misclassification exposure exists regardless of what the invoice says.
The Request That Sounds Like a Deal
It usually comes up mid-project, when the schedule is tight and the markup on the invoice starts to sting. A GC calls the staffing coordinator and asks whether the pipefitter can just be paid direct, 1099, cutting out the agency fee. On paper it looks like straightforward savings. In practice it converts a staffing arrangement, where someone else carries the employment risk, into a direct employment relationship with none of the protections that come with that role.
The mistake is treating 1099 status as a box you check by agreement. The IRS and the Department of Labor don't look at what the paperwork says the relationship is; they look at what the relationship actually functions like on the ground. A signed 1099 agreement does not override the facts of who's directing the work.
What Actually Determines the Classification
The test regulators apply, commonly called the economic realities test, comes down to control. Who sets the schedule and the hours. Who supplies the tools, ladders, and PPE. Who directs the day-to-day method of the work, versus just the end result. Whether the worker is running their own business with multiple clients and their own liability insurance, or showing up when told and taking direction from your foreman.
There's a real distinction between an independent trade sub and a solo tradesperson filling a staffing gap. A genuine sub owns an LLC, brings their own crew and equipment, bids a defined scope, and invoices against milestones. A welder who shows up at your call time, uses your man-lift, and works under your foreman's daily direction is functioning as an employee no matter what line item on the invoice says otherwise. That distinction is the whole test, and most contractors get it backwards because they focus on the invoice format instead of the working conditions.
Where the Exposure Lands When the Classification Is Wrong
If a worker paid as 1099 is later found to be functioning as an employee, the exposure isn't theoretical. It includes back payroll taxes, including the employer-side FICA match, plus back FUTA and state unemployment contributions that were never paid in. It includes retroactive overtime: 1099 workers typically don't get time-and-a-half, so a reclassification can trigger owed back overtime under the Fair Labor Standards Act for every week the misclassification was in effect.
The sharper exposure is workers' comp. A 1099 worker generally isn't covered by anyone's comp policy. If that person gets hurt on your site, there's no comp claim absorbing the cost and no exclusive-remedy shield protecting the GC from a lawsuit. The injury becomes a direct personal injury claim against whoever was functioning as the employer, which courts and the DOL will determine based on control, not contracts. Under joint-employer doctrine, a GC who directed the work day to day can be on the hook even when a staffing company or the worker's own paperwork says otherwise.
Why the Staffing Model Removes This Risk by Default
A staffing company built around skilled trades keeps its tradespeople on W-2, runs payroll tax withholding, and carries a workers' comp policy rated to the correct trade class code for electricians, pipefitters, or industrial mechanics. That structure isn't administrative overhead the agency tacks on for its own convenience. It's the actual product a GC is buying when they accept a bill rate above straight wage.
The markup buys the GC out of employer-of-record exposure. It means the comp claim goes to the agency's policy and NCCI experience rating, not the GC's, and the payroll tax and unemployment insurance obligations sit with the entity that's actually built to carry them. That's the trade being made, and it's worth naming explicitly the next time a bill rate gets questioned.
Red Flags: When 'Staffing' Is Quietly 1099 in Disguise
Some arrangements marketed as staffing are really 1099 placement with a service fee attached, and the red flags are consistent. The agency offers a cheaper 1099 rate as an alternative tier to its regular W-2 placement. The worker invoices the GC or plant directly instead of the staffing company. The worker has been embedded exclusively on one site for months while still carried as an independent contractor, which undercuts the multiple-clients test badly. The agency can't produce a workers' comp certificate naming itself as the employer of record for that specific worker and trade class.
The fix is to ask for the comp policy declaration page and the applicable NCCI class code before the worker steps on site, not after an incident forces the question. If an agency hesitates to produce it, that hesitation is the answer.
A Worked Hypothetical: What the Discount Actually Costs
Say a GC saves six dollars an hour by paying a pipefitter direct as 1099 instead of running the placement through the agency's blended bill rate. Across a thousand hours on a project, that's six thousand dollars in visible savings on the labor line. Now say that worker gets hurt, or the arrangement gets flagged in an audit. Reclassification brings back employer-side FICA, roughly 7.65 percent of everything paid, plus retroactive overtime for every week worked over forty hours, plus the full cost of an injury claim with no comp policy standing between the GC and the lawsuit.
The six thousand dollars in savings doesn't offset any of that, because the exposure isn't capped at the hours worked on one project. It applies to every hour logged under that classification, and it surfaces all at once instead of showing up as a line item you can plan around. That asymmetry, small visible savings against a single uncapped incident, is the actual math worth running before taking the 1099 shortcut.
Frequently asked
Can a skilled tradesperson legally work as a 1099 contractor on my jobsite?
Only if they meet the control test in substance, not just on paper: they set their own schedule, bring their own tools, run their own business serving multiple clients, and bid or invoice against a defined scope rather than taking daily direction from your foreman. A solo tradesperson filling a staffing gap under your supervision, using your equipment, on your schedule, does not meet that test regardless of how the invoice is structured.
What happens if a worker classified as 1099 gets hurt on my site?
Because 1099 workers typically aren't covered by anyone's workers' comp policy, an injury becomes a direct personal injury claim rather than a comp claim. There's no exclusive-remedy shield protecting whoever was functioning as the employer, and under joint-employer principles that can be the GC even if a staffing company or the worker's own paperwork says otherwise.
Does using a staffing agency eliminate my misclassification risk entirely?
It eliminates it when the agency employs the tradesperson on W-2, runs their payroll taxes, and carries the workers' comp policy on the correct trade class code. It does not eliminate the risk if the arrangement is actually 1099 placement wearing a staffing label, which is why it's worth confirming the worker's employment status and the agency's comp coverage before the project starts, not after an incident.
How do I tell if my staffing agency is actually using W-2 employees?
Ask directly for the workers' comp policy declaration page and the NCCI class code covering the specific trade and worker, and confirm the worker is paid through the agency's payroll rather than invoicing you or the site directly. An agency that employs tradespeople on W-2 should be able to produce this without hesitation; reluctance or a cheaper 1099 pricing tier offered as an alternative is the clearest sign the arrangement isn't what it's being called.
