If you own a business and pay people to work for you, classification matters. Getting it wrong can trigger an IRS audit, back taxes, fines, and even lawsuits. The difference between an employee and an independent contractor comes down to taxes, control, and how the relationship works day to day.
Here’s what you need to know to classify your workers correctly.
Key Takeaways:
- Employers must withhold income tax, Social Security, and Medicare from employee wages. Independent contractors pay their own taxes.
- The IRS uses three main tests to determine worker status: behavioral control, financial control, and the type of relationship.
- Misclassifying an employee as a contractor can result in back taxes, interest, fines per worker, and potential lawsuits.
- When in doubt, the IRS defaults to treating a worker as an employee. You should do the same.
- You can file IRS Form SS-8 to request an official determination on a worker’s status.
What’s the Difference Between an Employee and an Independent Contractor?
Your company can pay an employee and a contractor for the same type of work. The legal and tax obligations, though, are completely different.
For employees, you withhold federal and state income taxes, Social Security, and Medicare (FICA) from their wages. You also pay your share of FICA taxes and unemployment tax. These amounts show up on each paycheck and on the employee’s W-2 at year end.
For independent contractors, you don’t withhold anything. The contractor is responsible for paying their own income taxes and self-employment taxes. You report what you paid them on a 1099 form.
Here’s where business owners get into trouble. Hiring contractors can save roughly 30% in payroll-related costs. That makes it tempting to label everyone a contractor. But just calling someone a contractor doesn’t make it true, and the IRS knows it.
How Does the IRS Decide if Someone Is an Employee or Contractor?
The IRS doesn’t have one single test. They evaluate each situation individually using three categories.
Behavioral Control
This is about who directs the work. If you control when the person works, what tools they use, what tasks they perform, and how they do the job, that worker is likely an employee.
If the worker sets their own hours, uses their own methods, and operates with little direction from you, that points toward independent contractor status.
For example, if you tell a salesperson to sit at a desk and make calls from 9 a.m. to 5 p.m., that person looks like an employee. If you tell a salesperson to go sell 20 units however they see fit, that person looks like a contractor.
Financial Control
The IRS looks at how the worker gets paid and whether they can profit or lose money on the arrangement.
An employee usually receives a regular salary or hourly wage on a set schedule, every week or every two weeks. A contractor typically gets paid per project or per sale, with no guaranteed amount.
Salespeople can make this tricky. Commission-based pay usually points toward contractor status. But if a salesperson receives a “draw” against future commissions, a company car, or expense reimbursements, courts have ruled those arrangements look more like employment.
Other financial factors the IRS considers include whether the worker can take on clients from other companies, and whether the worker has their own LLC or business entity.
Type of Relationship
The IRS also looks at the nature of your working relationship.
If a worker receives benefits like health insurance, vacation pay, or a pension plan, that signals an employee relationship. If customers associate the worker with your company through a uniform, name tag, or listing on your website, that also weighs toward employment.
A contractor relationship tends to be project-based and temporary. Contractors can turn down assignments. They can even hire someone else to do the work for them. And if you terminate a contractor mid-project, you may still owe them for the remaining work.
Employees, on the other hand, report to you on a broader range of activities, receive regular performance reviews, and can generally be terminated at will.
Does Training Matter for Classification?
Yes. If you train a worker on how to do their job, that’s a strong sign they’re an employee. Contractors are hired because they already know how to do the work. You pay them for results, not for learning your processes.
If you’re providing ongoing professional development, onboarding sessions, or skills training, the IRS will likely view that worker as an employee.
Do Employment Laws Apply to Contractors?
Federal employment and labor laws under OSHA, the ADA, and the EEOC apply to employees. They generally do not apply to independent contractors.
That said, hiring contractors doesn’t remove your obligation to maintain a safe work environment. People can still take legal action against your business if they’re injured while doing work for you, regardless of their classification.
What About Statutory Employees?
There’s a third classification that trips people up. A statutory employee is treated as independent from the company in most ways but is classified as an employee for tax purposes.
The IRS recognizes four specific categories of statutory employees:
- Delivery drivers who distribute beverages (non-milk), produce, meat, or baked goods on commission
- Full-time life insurance agents who primarily sell for one company
- Home-based piece workers who use materials you supply and return finished goods to you
- Traveling salespeople whose primary work involves taking orders for merchandise on your behalf
If a worker fits one of these categories, you need to withhold FICA taxes from their pay even if they look like a contractor in other respects. The IRS has a page on Statutory Employees with specific filing requirements.
What Does the Department of Labor Look At?
The Department of Labor relies on Supreme Court precedent when evaluating worker classification under the Fair Labor Standards Act (FLSA). Their analysis goes beyond the IRS criteria.
The DOL considers factors like how central the worker’s services are to your business, how permanent the relationship is, how much the worker invests in their own equipment and facilities, and how much independent judgment the worker uses in the open market.
They also apply the “economic realities test,” which asks whether the worker is economically dependent on your business. If the answer is yes, the DOL is more likely to consider that person an employee.
Each state has its own version of these tests for unemployment insurance and workers’ compensation purposes, too. Check your state workforce agency’s website for specific rules.
What Happens if You Misclassify a Worker?
This is where the real cost shows up. If the IRS determines you classified an employee as an independent contractor without a reasonable basis, you’re on the hook for all the employment taxes you should have paid, plus interest and penalties.
The penalties add up fast. You’ll owe a fine for each misclassified worker, the back taxes you never withheld, and accumulated interest for every month those taxes went unpaid.
I’ve seen business owners assume they’d save money by classifying everyone as contractors. In almost every case, the penalties from an audit far exceeded what they would have spent on payroll taxes.
It gets worse if the IRS believes the misclassification was intentional. That opens the door to criminal and civil penalties.
Workers can also report you. Anyone who believes they’ve been improperly classified can contact the IRS anonymously or file Form 8919 to report uncollected Social Security and Medicare taxes. The federal government has prioritized going after companies that misclassify workers, particularly in the restaurant, hotel, construction, retail, and manufacturing industries. They’ve recovered billions of dollars from enforcement actions.
Legal Exposure from Misclassification
Misclassified workers can sue for back wages, unpaid overtime, and minimum wage violations. Under the Fair Labor Standards Act, they can recover up to double what they’re owed in liquidated damages.
They may also be eligible for expense reimbursement, unemployment insurance, and workers’ compensation benefits once a court determines they should have been employees. If multiple workers are misclassified, a class-action lawsuit becomes a real possibility, and that can damage your finances and your reputation.
When You’re Not Sure, Assume Employee
The IRS defaults to employee status when classification isn’t clear. You should do the same.
If you want an official answer, file IRS Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding. The IRS will review the details of your working relationship and issue a determination. Keep in mind they won’t rule on hypothetical situations. You need to submit the form based on a real working arrangement.
You can also reference IRS Publication 1976, which covers Section 530 Employment Tax Relief Requirements. Some employers with a reasonable basis for their classification may qualify for relief from back employment taxes.
The Voluntary Classification Settlement Program (VCSP) is another option. If you’re currently treating workers as contractors and want to reclassify them going forward, the VCSP lets you do so with reduced penalties.
Should You Hire Employees or Contractors?
That depends on your business needs and budget.
If you need someone working with you every day, handling a variety of responsibilities, and growing with your company long-term, you need an employee. You’ll pay more in payroll taxes and benefits up front, but you gain control over how the work gets done and build a team invested in your business.
If you need someone for a specific project, a defined scope of sales work, or short-term support, a contractor may be the better fit. You’ll pay less in taxes, skip the benefits obligations, and get someone who works independently.
The key is to classify correctly from day one. And revisit those classifications periodically, because a contractor relationship can gradually shift into an employee relationship over time as responsibilities change.
