Employee or Contractor? Why Getting It Wrong Can Cost You Years Later
It’s Friday afternoon. You’re cutting checks, and one of your regular helpers asks to be paid “the usual way” with no withholding, no payroll, just a 1099 at the end of the year. It feels simpler for everyone. Fewer forms, less tax to deposit, and they seem happy with it.
Here’s the hard truth we see far too often: whether someone is an employee or an independent contractor is not something you and the worker get to decide. The IRS and the State of Wisconsin decide, using their own tests, and they can look back years after the fact. When the answer doesn’t match what you’ve been doing, the bill lands on you, not the worker.
Let’s walk through how each agency looks at it, how to make the call with confidence, and what happens if it’s wrong.
How the IRS Looks at It
The IRS uses what’s called the common-law test. The big question is simple: who controls the work? The IRS groups the facts into three areas.
Behavioral control. Do you tell the person how, when, and where to do the job? Do you train them on your methods? If so, that points toward employee.
Financial control. Does the worker have their own business investment, tools, and expenses that aren’t reimbursed? Can they make or lose money on the job? Do they work for other customers? Those point toward contractor.
Relationship of the parties. Is there a written contract? Do they get benefits? Is the work ongoing and a core part of what your business does? A permanent role doing your main work looks like employment, regardless of what the paperwork says.
No single factor decides it. The IRS weighs the whole picture. If you truly can’t tell, either party can file Form SS-8 and ask the IRS for a determination, though that can take months.
How Wisconsin Looks at It
This is where many business owners get caught off guard, because Wisconsin isn’t one agency with one test.
Those nine conditions cover things like:
Maintaining a separate business with their own office, equipment, and materials
Controlling how the work gets done under a contract for specific services
Paying their own main business expenses and carrying ongoing business liabilities
Being responsible for finishing the job right, and liable if they don’t
Being paid by the job or by commission rather than by the hour
Having a real chance to make a profit or take a loss
Advertising or offering their services to the public
The practical takeaway: someone can pass the IRS test and still fail Wisconsin’s. And a worker having an LLC or a business card does not automatically make them a subcontractor. A true subcontractor runs a real business, carries its own insurance, and serves other customers. If your “sub” doesn’t carry worker’s comp, your policy can end up responsible when they get hurt on your job.
If It’s Wrong, Here’s What It Costs
This is the part that keeps owners up at night once they understand it. The consequences stack.
Back payroll taxes. The IRS can assess your share of Social Security and Medicare for every reclassified worker, plus a portion of the taxes you should have withheld from them. If you didn’t file 1099s, that portion goes up. If the IRS decides you intentionally ignored the rules, you can be on the hook for the full amount.
Penalties and interest. Failure-to-deposit, failure-to-file, and W-2 penalties pile on top, and interest runs from the original due dates.
Personal liability. Unpaid withheld taxes can trigger the Trust Fund Recovery Penalty, which lets the IRS pursue owners and responsible people personally, not just the business.
Wisconsin unemployment. DWD can bill back unemployment contributions with interest. In construction and drywall or painting work, knowingly misclassifying workers can bring an added penalty of $500 per worker, up to $7,500 per incident, and coercing someone into contractor status can cost $1,000 per worker, up to $10,000 a year. Criminal penalties are possible for intentional cases.
Worker’s compensation. Operating without required coverage brings its own penalties, and an injury claim from an uninsured worker can be devastating.
Wage claims. A reclassified worker may also be owed overtime and other wages they were never paid.
And it rarely stops at one worker or one year. An audit that starts with a single unemployment claim from a former helper can open up every 1099 you’ve issued.
If You Think You Have a Problem
There are ways to fix this before an agency finds it. The IRS Voluntary Classification Settlement Program lets eligible businesses start treating workers as employees going forward and settle past federal employment tax at a significant discount. Section 530 relief may also protect businesses that had a reasonable basis for their treatment and filed 1099s consistently. Neither one fixes Wisconsin issues on its own, so it pays to look at both sides together.
What This Means for Your Business and Your Life
Getting this right isn’t only about avoiding a tax bill. It means you can grow your crew without wondering which hire is going to trigger an audit. It means a former worker’s unemployment claim is a routine form, not a crisis. It means knowing that if someone gets hurt on a job, they’re covered and your business is protected. And honestly, it means one less thing sitting in the back of your mind on a Sunday night.
What It Takes to Get Started
Start with a simple review. Gather a list of everyone you paid outside of payroll this year, what they do for you, how they’re paid, and whether they carry their own insurance. We’ll walk through each one against both the IRS and Wisconsin tests, flag anyone who looks risky, and help you set up payroll the right way where it’s needed. If something needs correcting, we’ll help you choose the cleanest path forward.
