Getting worker classification wrong is expensive. If the IRS determines someone you’ve been paying as a 1099 contractor is actually an employee, you owe back payroll taxes, penalties, and interest. You could also face claims for unpaid benefits, workers’ comp coverage, and overtime. These rules exist to prevent businesses from avoiding tax obligations by mislabeling employees as contractors.

The IRS uses three main factors to determine classification. These are behavioral control, financial control, and the type of relationship.

Behavioral control looks at who directs how the work gets done. If you tell someone when to show up, what tools to use, and how to complete each task, that points toward employee. If you hire someone to finish a specific scope and they decide how to accomplish it, that points toward contractor.

Financial control considers the business side. Contractors typically have significant investment in their own equipment, work for multiple clients, carry their own insurance, and have opportunity for profit or loss on a job. Employees use company equipment, work primarily for one employer, and get paid regardless of project outcome.

The type of relationship looks at the overall arrangement. Written contracts, permanence of the relationship, and whether benefits are provided all factor in. An ongoing, indefinite relationship without a contract looks more like employment than a contractor arrangement.

For general contractors and construction companies along the Wasatch Front, this usually breaks down clearly. Your crew members who show up daily, use your tools, follow your schedule, and work under direct supervision are employees. A plumber you hire to rough in a house who brings their own tools, carries their own liability and workers’ comp, works for other builders, and bills for the completed scope is a contractor.

Problems happen when the lines blur. A “subcontractor” who only works for you, uses your equipment, and takes direction on how to perform every task isn’t really a subcontractor. Calling them one doesn’t change the legal reality. Agencies look at substance over labels when they audit.

Some warning signs of potential misclassification include the worker being with you for years without working for anyone else, not having their own business entity or contractor license, you providing all their tools, you controlling their daily schedule, or paying them hourly instead of by the job.

If you’re unsure about a specific worker, the IRS offers Form SS-8 to request a formal determination. Filing that form invites scrutiny though. A better first step is often reviewing the situation with a construction bookkeeper in American Fork who understands how the trades industry works and can help you evaluate your current setup before it becomes a problem.

Getting classification right from the start matters for your books too. Employees require payroll with tax withholding, quarterly filings, and labor law compliance. Legitimate subcontractors need W-9s, written contracts, and certificates of insurance. Mixing these up creates headaches at tax time and leaves you exposed if an agency decides to audit.
