The core difference comes down to control. A W-2 employee works under your direction. You set their hours, tell them how to do the work, provide the tools, and control the process. A 1099 contractor operates independently. You define the result you want, but they decide how and when to get it done.

That distinction drives everything else, especially on the tax and financial side. With a W-2 employee, you withhold federal and state income taxes, Social Security, and Medicare from their paycheck. You also pay the employer portion of Social Security and Medicare (7.65% of wages), plus federal and state unemployment taxes. With a 1099 contractor, you pay them the agreed amount and that’s it. No withholding, no employer tax contributions. They handle their own taxes, including self-employment tax.

The cost difference is significant. On top of wages, a W-2 employee typically costs an additional 20-30% when you factor in employer payroll taxes, workers’ comp insurance, and any benefits you offer. A contractor at $50/hour costs you exactly $50/hour. That math makes contractors look cheaper, but it only works when the relationship genuinely qualifies as independent contracting.

The IRS looks at three categories when determining classification: behavioral control, financial control, and the type of relationship. If you control when someone works, how they do their work, provide their equipment, and they only work for you, that looks like an employee regardless of what your contract says. Calling someone a 1099 contractor doesn’t make them one.

Misclassification is where businesses get into real trouble. If the IRS or Tennessee Department of Revenue determines you’ve been treating employees as contractors, you owe back payroll taxes, penalties, and interest. You could also face liability for unpaid benefits and overtime. This has become a bigger enforcement priority in recent years, and it’s not just large companies getting audited.

A few practical rules of thumb. If the person sets their own schedule, works for multiple clients, provides their own tools, and controls how the work gets done, they’re likely a contractor. If they work set hours at your location, use your equipment, and you direct their daily tasks, they’re likely an employee. Many situations fall in a gray area, which is why getting it right matters.

When you do work with contractors, proper documentation is essential. You need a W-9 from each contractor before you pay them, and you’ll need to file a 1099-NEC for anyone you pay $600 or more during the year. Our 1099 preparation service handles the filing side, but the classification decision needs to happen before you ever issue that first payment.

If you’re unsure about how to classify someone, get it sorted out before you hire. Fixing a misclassification problem after the fact is expensive. Proper bookkeeping services will track your labor costs differently for employees and contractors, which keeps your books clean and makes tax time straightforward. But the classification itself is a decision you need to make intentionally, not just default to whichever option feels easier.
