Worker misclassification is one of the most expensive mistakes a contractor can make. Classifying workers as independent subcontractors when they should be employees can result in back taxes, penalties, and fines that total hundreds of thousands of dollars.
Why Classification Matters
When you hire an employee, you're responsible for withholding income taxes, paying Social Security and Medicare taxes, paying unemployment taxes, providing workers compensation insurance, and complying with wage and hour laws. When you hire an independent subcontractor, none of those obligations apply. The cost difference can be 30% or more of the worker's pay.
This cost difference creates a strong incentive to classify workers as subcontractors even when they should be employees. But the IRS, state tax agencies, and labor departments actively audit and enforce classification rules.
The IRS Test
The IRS uses a multi-factor test that examines three categories: behavioral control, financial control, and the type of relationship. Behavioral control asks whether you direct when, where, and how the work is done. If you set the worker's hours, provide detailed instructions on methods, and supervise their work closely, that suggests an employee relationship.
Financial control examines whether the worker has a significant investment in their own tools and equipment, whether they can profit or lose money on the job, and whether they provide services to multiple clients. A worker who uses your tools, works exclusively for you, and is paid by the hour looks more like an employee.
The type of relationship considers whether there's a written contract, whether you provide benefits, and whether the relationship is expected to be ongoing or project-based.
Common Misclassification Scenarios
Hiring a "helper" who works exclusively for you, uses your tools, and follows your daily instructions is almost certainly an employee, even if you pay them on a 1099. Having a crew of "independent contractors" who show up at the same time every day, use your equipment, and take direction from your foreman is an employee arrangement regardless of what the paperwork says.
The Penalties
If the IRS determines you misclassified employees, you'll owe back employment taxes plus penalties and interest. State agencies may assess additional penalties for unemployment insurance and workers compensation violations. The total exposure can easily exceed $100,000 for even a small operation, going back three or more years.
Getting It Right
To properly classify workers as independent subcontractors, they should have their own business entity and contractor's license. They should provide their own tools and equipment. They should control how, when, and where the work is done. They should have multiple clients, not just you. They should have a written subcontract agreement. They should carry their own insurance.
If your working relationship doesn't meet these criteria, the worker is likely an employee, and you should classify and pay them accordingly. The short-term cost of proper classification is far less than the long-term cost of getting caught misclassifying.
