You needed help, so you brought someone on. Maybe a part-time bookkeeper, a designer, or a few people to cover shifts. You paid them by invoice and called them a contractor because it seemed simpler.
But calling someone a contractor doesn’t necessarily make them one. And if the IRS disagrees, that decision can come with back taxes, penalties, and interest.
With 1099 season approaching, now’s a good time to look at who’s working for your business, how you’re paying them, and whether you’ve classified them correctly.
Contractor vs. Employee: what’s the difference?
The difference comes down to control. An employee works the way you direct, on your schedule, as part of your business. A contractor runs their own business and decides how to get the result you’re paying for.
The label you choose doesn’t decide it. Neither does a signed contract. The IRS looks at how the work actually happens.
Employee (W-2) | Contractor (1099) | |
|---|---|---|
Who decides how the work is done | You | They do |
Schedule | Set by you | Set by them |
Tools and equipment | You provide them | They bring their own |
How they’re paid | Hourly or salary, on payroll | Per project or invoice |
Taxes withheld | Yes: income tax, Social Security, Medicare | No: they pay their own |
Your extra taxes | Your share of Social Security and Medicare (7.65%), plus unemployment tax | None |
Benefits | You may need to offer them | Not eligible |
Year-end form | W-2 | 1099-NEC (if paid $2,000+) |
Other clients | Usually not | Usually yes |
For a small business owner, is it better to hire an employee or a contractor?
Neither is better across the board. It depends on the work, not on which one costs less.
A contractor makes sense when:
The work is a project with a clear end, like a website redesign or a one-time cleanup
You need a skill you don’t use every week
The person already has their own business, tools, and other clients
You care about the results, not how they get there
An employee makes sense when:
The work is ongoing and central to how your business runs
You need to set their hours, train them, or review how they work
They’ll represent your company to customers
You want them to grow with you
The real cost difference. A contractor looks cheaper because you skip payroll taxes, benefits, and the paperwork. An employee costs more than their pay: your share of Social Security and Medicare is 7.65% of wages, plus federal and state unemployment tax, workers’ comp, and any benefits.
But that saving only holds if the person is truly a contractor. If they aren’t, you end up paying those taxes anyway, plus penalties.
7 signs your contractor might actually be an employee
Most founders start with contractors, and that’s fine. The trouble starts when a contractor slowly turns into an employee, and nobody updates the paperwork.
Say you hire a freelance operations assistant for a few hours a week. Six months later, they’re working Monday through Friday, using your company laptop, attending team meetings, and following your daily schedule. You’re still paying their invoices, but the working relationship has changed. What started as freelance work may now look a lot like employment.
Watch for these signs:
They work only for you. They have no other clients, and your business is their main income.
You set their schedule. They’re expected online or on-site at certain hours.
You tell them how to do the work, not just what result you need.
They use your stuff: your laptop, email address, software, or workspace.
The project never ends. Their “three-month contract” is now in its second year.
They do your core work. If your business couldn’t run without what they do, that’s a strong sign.
You’re training them on how your company does things.
There’s no magic number. The IRS says no fixed set of factors decides it; it looks at the whole relationship. If several of these sound familiar, it’s worth a closer look.
At what point is a contractor considered an employee?
A contractor becomes an employee when you control how they work, not just what they deliver. The IRS looks at three areas, and no single one decides it (IRS):
Area | The question | Points to employee |
|---|---|---|
Behavioral control | Do you direct how the work gets done? | You set methods, hours, and training |
Financial control | Who controls the business side of the job? | Hourly pay, you cover expenses, you supply tools |
Relationship | How do both sides treat the arrangement? | Ongoing work, core to your business, benefits |
The Department of Labor has its own test for minimum wage and overtime. In February 2026, it proposed a rule that focuses on two core questions: who controls the work, and whether the worker can make or lose money on it (Butler Snow). As of this writing, it’s still a proposal. Some states, including California, use a stricter test that makes it harder to call someone a contractor.
What it costs to get it wrong
What you owe depends on the facts, including how many workers and years are involved, whether you filed 1099s, and whether the misclassification was an honest mistake or intentional. If the IRS reclassifies a worker, you can owe (TaxBuzz):
Taxes you should have withheld from their pay. For honest mistakes, federal law sets reduced rates: 1.5% of wages plus 20% of the worker’s share of Social Security and Medicare, or 3% and 40% if you never filed 1099s. Intentional misclassification can mean owing the full amounts.
Your own share of Social Security, Medicare, and federal unemployment tax
Penalties and interest, including late deposit penalties (see our guide to payroll tax penalties)
State back taxes and penalties, plus possible claims for overtime or benefits the worker missed
This happens to small businesses, not just big companies. In January 2025, two Louisiana home care providers had to pay $446,334 after the Department of Labor found they had treated 88 workers as independent contractors and paid them straight-time rates for hours over 40, with no overtime (U.S. Department of Labor).
“Providing a 1099 or contractor agreement does not determine status by itself. If workers are later found to be employees, exposure can include back wages and overtime, liquidated damages, payroll taxes, unemployment contributions, workers’ compensation, benefits issues, penalties and legal fees.”

Not sure? You have options
Ask the IRS. Form SS-8 gets you an official ruling, though it can take six months or more.
Fix it going forward. The IRS Voluntary Classification Settlement Program lets you reclassify workers as employees with partial relief on past taxes, if you qualify.
Ask an expert before you hire the next person, not after.
Before January: your contractor checklist
The 1099 rules changed for 2026. You now send a 1099-NEC to a contractor only if your reportable payments to them reached $2,000 or more during the year, up from $600 (Patriot Software). Payments you made by credit card or through a payment app like PayPal are generally reported by the payment company on Form 1099-K instead, so you don’t include those. The deadline is normally January 31, which falls on a Sunday in 2027, so 1099s for 2026 are due February 1, 2027.
List everyone you paid outside of payroll this year, how much, and how you paid them
Collect a W-9 form from anyone you’re missing
Flag anyone whose reportable payments reached $2,000 for a 1099-NEC
Run each regular contractor through the seven signs above
Have an HR or payroll expert review questionable classifications and decide what corrections are needed
Going forward, get a W-9 before the first payment
FAQ
Can I hire an LLC in place of an employee?
You can pay someone’s LLC, but it doesn’t settle the question. If you still control how and when they work, the IRS can treat them as your employee, LLC or not.
What’s the difference between a W-2 and a W-9?
A W-2 is the year-end wage form you give employees. A W-9 is the form a contractor gives you with their tax ID so that you can send them a 1099-NEC later. Collect the W-9 before you pay them.
As a business owner, should I do W-2 or booth rental?
In salons and similar businesses, a true booth renter pays you rent and runs their own book: their own clients, prices, hours, and products. If you set their schedule, prices, or services, they’re likely an employee, even if you call it booth rental.
What benefits am I required to give part-time employees?
It depends on your state and your size. Most states require workers’ compensation and unemployment insurance, and some require paid sick leave. Federal health coverage rules generally apply once you have 50 or more full-time equivalent employees. Check your state’s rules before your first hire.
Can a contractor work full-time hours?
Yes, hours alone don’t decide it. A contractor can work 40 hours a week for you and still be a contractor if they control how they work and run their own business. But full-time hours for one client, on a schedule you set, is one of the signs that the relationship may have become employment.
