Employee or Contractor: How the IRS Decides
The three-part control test, what guessing wrong costs, and the two relief programs
Every worker you add for the fall season is one of two things to the IRS, an employee or an independent contractor, and the difference is who controls the work, not what the contract says.[1] The label decides who pays what:
| If they are an employee | If they are a contractor |
|---|---|
| You withhold income tax and split Social Security and Medicare with them | They pay all 15.3 percent of self-employment tax themselves[1] |
| You give them a W-2 every January | You file a 1099-NEC for them |
| You also pay federal unemployment tax | You pay the invoice and nothing else |
The test is control, in three parts
The IRS weighs three kinds of evidence:[1]
- Behavioral control: does the business direct how the work gets done, not only the result? Set hours, required methods, and training all point toward employee.
- Financial control: who bears the business side? A worker who invests in their own tools, covers their own expenses, and can profit or lose on a job looks like a contractor.
- Relationship: benefits, permanence, and work that is central to your business all point toward employee, whatever the contract is titled.
No single factor decides; the IRS weighs the relationship as it actually operates. A framing sub with their own crew, their own tools, and three other builders is a contractor, while a sub who works your schedule with your tools, only for you, is probably an employee.
What guessing wrong costs
Misclassify a worker without a reasonable basis, and the business owes the back employment taxes, plus penalties and interest.[1]
When a relationship is genuinely unclear, either side can ask the IRS to decide by filing Form SS-8, and a determination takes at least six months.[2]
The two relief programs
- Section 530: erases the back taxes if you had a reasonable basis for calling the worker a contractor, treated every similar worker the same way, and filed the 1099s consistently. Without the 1099s on file, there is no relief.[3]
- The VCSP: the Voluntary Classification Settlement Program lets you reclassify workers going forward by filing Form 8952 at least 120 days ahead and paying 10 percent of one year's employment taxes on their pay, computed at reduced rates, with no penalties, no interest, and no employment tax audit of prior years.[4]
The bottom line
Decide the classification before the first check, collect the W-9 the same day, and keep the 1099 habit, now with a $2,000 threshold, that keeps Section 530 open. Classification even reaches the owner: an S-corp owner who works in the business is an employee of their own company.
If a current worker is hard to classify, a free consultation is a cheaper second opinion than an audit.
