1099 vs. W-2: What's the Difference and Why It Matters
Misclassifying workers as contractors instead of employees is one of the most costly mistakes a business owner can make. Here's how to tell the difference and stay compliant.
One of the most common — and costly — mistakes small business owners make is misclassifying employees as independent contractors. The IRS takes this seriously, and the penalties can be severe. Here's what you need to know.
The Difference
W-2 Employee:
- Works under your direction and control
- You set their schedule, provide tools, and direct how work is done
- You withhold and pay payroll taxes (Social Security, Medicare, federal and state income tax)
- You may provide benefits
- You issue a W-2 at year-end
1099 Contractor:
- Works independently, controls how they complete the work
- Sets their own schedule, uses their own tools
- Responsible for their own taxes (self-employment tax)
- No benefits required
- You issue a 1099-NEC if you paid them $2,000 or more in a year
The IRS Test
The IRS uses a multi-factor test to determine worker classification, focusing on three categories:
- Behavioral control — Do you control how the worker does their job?
- Financial control — Do you control the business aspects of the worker's job?
- Type of relationship — Is there a written contract? Are there employee-type benefits?
No single factor is determinative — it's the totality of the relationship.
Why Misclassification Is Risky
If the IRS determines you've misclassified an employee as a contractor, you could owe:
- Back payroll taxes (both employer and employee portions)
- Penalties and interest
- Back benefits
- State penalties
The IRS has a voluntary correction program (Section 530 relief) for some situations, but it's far better to get it right from the start.
When in Doubt
If you're unsure how to classify a worker, you can file Form SS-8 to ask the IRS for a determination. Or consult a tax professional before you hire.
