Contractors, Employees & 1099s: The Compliance Guide
Employees (W-2) vs. Contractors (1099): Forms, Taxes & Contracts
Classifying a worker as an employee or an independent contractor has major legal and tax consequences. Get it wrong — treating someone as a contractor when the IRS sees an employee — and you face back payroll taxes, penalties, and state labor enforcement. This guide makes the distinction clear, then shows exactly what we need to set up your payroll.
Employee vs. Contractor at a Glance
| Employee (W-2) | Contractor (1099) | |
|---|---|---|
| Who controls the work | You set hours, methods & tools | Worker controls how & when |
| Tax form | W-2 | 1099-NEC |
| Who pays payroll tax | Employer withholds & matches | Contractor pays own |
| Benefits | Often provided | None |
| Onboarding form | W-4 | W-9 (US) / W-8BEN (foreign) |
| Relationship | Ongoing / indefinite | Project-scoped |
How the IRS Decides: The Three-Factor Test
Do you direct how the work is done — hours, tools, supervision, sequence? More control points to employee.
Can the worker profit or lose, serve multiple clients, and supply their own equipment? That points to contractor.
Written contract? Benefits? Indefinite vs. project-based? Permanent, benefits-included work looks like employment.
Quick Classification Flow
The Forms, Decoded
- W-4 — every U.S. employee completes this so you withhold the right federal income tax.
- W-2 — you issue this to employees each January, reporting wages and taxes withheld.
- W-9 — U.S. contractors give you this (name, address, TIN) so you can issue their 1099.
- W-8BEN — foreign contractors complete this to certify non-U.S. status and treaty benefits.
- 1099-NEC — you issue this to U.S. contractors paid $600 or more in the year.

1099 Season Survival Guide for Business Owners
If your business paid any contractor or freelancer $600 or more during the calendar year, you must issue Form 1099-NEC by January 31. Missing this deadline triggers IRS penalties that compound quickly.
Which Form to Use
- 1099-NEC — contractor and freelancer service payments (any individual, sole prop, or LLC not taxed as a corporation)
- 1099-MISC — rents, royalties, prizes, medical payments, and attorney fees
- Do NOT issue 1099s to: corporations (C-Corp or S-Corp), your own employees (they get W-2s), or payments made via credit card or third-party processors like PayPal (those go on Form 1099-K from the processor)
Key Deadlines
- January 31 — furnish copies to recipients AND file with the IRS (same date for 1099-NEC)
- February 28 / March 31 — paper / e-file deadline for 1099-MISC
Penalties for Missing Deadlines
- $60/form — filed within 30 days of deadline
- $130/form — filed 31 days late through August 1
- $330/form — filed after August 1 or never filed
The W-9 Rule — Single Most Important Step
Collect a signed W-9 from every new contractor before making the first payment — not in January. If a contractor refuses to provide a W-9 or gives an incorrect TIN, you must withhold 24% backup withholding from every payment and remit it to the IRS. Keep W-9s for at least 3 years after the last payment.
