Why This Matters: The IRS Takes Misclassification Seriously
Treating an employee as a contractor can leave federal employment taxes unpaid. If an agency reclassifies a worker, the employer may owe taxes, interest, and penalties. The period and amount depend on the return history and facts; a blanket three-year or six-year rule is not reliable.
The Department of Labor also enforces misclassification rules independently, with separate penalties and back-wage requirements under the Fair Labor Standards Act.
A written classification review is safer than assuming a common industry practice is correct.
The IRS Common Law Test
The IRS uses a multi-factor analysis based on three broad categories of control:
1. Behavioral Control
Does the company control how the worker does the job, not just the result, but the method?
- Does the company provide training on how to do the work? (Employee indicator)
- Does the company dictate when, where, and how the work is done? (Employee indicator)
- Does the worker use their own methods and tools? (Contractor indicator)
2. Financial Control
Does the company control the business aspects of the worker’s job?
- Is the worker paid a fixed wage or salary regardless of hours? (Employee indicator)
- Does the company reimburse expenses? (Employee indicator)
- Does the worker have a significant investment in their own tools/facilities? (Contractor indicator)
- Can the worker profit or lose money based on how they manage the work? (Contractor indicator)
- Does the worker offer services to the general market? (Contractor indicator)
3. Type of Relationship
- Is there a written contract? (Contractor language helps but doesn’t control)
- Does the company provide employee benefits (insurance, pension, vacation pay)? (Employee indicator)
- Is the relationship permanent or indefinite? (Employee indicator)
- Is the work a key aspect of the company’s regular business? (Employee indicator)
Washington Uses Different Worker Tests
Do not apply one three-part ABC checklist to every Washington obligation. The IRS uses federal common-law factors for federal employment taxes. Washington agencies apply their own rules for unemployment insurance, workers’ compensation, and wage and hour rights. A result under one system does not automatically decide the others.
- Workers’ compensation: Washington L&I first considers the personal-labor test. When that does not exempt the worker, its six-part test applies, with an additional part for construction. The test includes business registration, tax filing, and separate-record requirements beyond control, place of work, and an independent trade. See L&I’s independent contractor guidance.
- Unemployment insurance: Washington ESD applies its own statutory independent-contractor requirements. Check the actual working arrangement with ESD’s worker-status guidance.
- Wage and hour rights: Washington L&I uses an economic-realities analysis for Minimum Wage Act questions. Review the facts of the relationship rather than relying on a contract label or a three-question shortcut.
Keep a separate, documented classification analysis for each obligation. A Form 1099, business license, or invoice alone does not establish an exemption.
Real-World Scenarios
| Situation | Likely Classification | Why |
|---|---|---|
| Graphic designer who works for multiple clients, sets their own hours, uses their own equipment | Needs review | These facts support independent operation but do not establish the result under every federal and Washington test |
| Full-time worker doing the company’s core work, on a set schedule, with company tools, paid via 1099 | Employee | Control over method and schedule, integral to business |
| IT consultant on a 6-month project, works with other clients, invoices by the hour | Needs review | Project duration and invoices alone do not decide federal or Washington classification |
| Delivery driver classified as contractor by gig platform | Contested, state-dependent | Many states are reclassifying gig workers under ABC test |
If You’re Already Misclassifying: Section 530 Relief
Section 530 relief can limit federal employment-tax liability in some worker-classification cases, but reasonable basis alone is not enough. The IRS also requires reporting consistency and substantive consistency. Relief does not decide the worker’s status under Washington law. Review the IRS Section 530 requirements with a qualified tax professional before relying on them.
The Bookkeeping Angle
Misclassification has bookkeeping consequences beyond the payroll tax exposure. If workers are reclassified, their compensation moves from “contract labor” (Schedule C expense) to “payroll”, a different line with different tax treatment, different reporting, and different accounts on the balance sheet (payroll liabilities). If you have 1099 contractors who should be employees, this affects your P&L, your balance sheet, your payroll tax deposits, and your state reporting.
If a worker may have been misclassified, review the payroll records and liabilities with the appropriate tax and employment professionals. A bookkeeping review can identify recording gaps; it does not determine legal worker status.

Common questions
Does issuing Form 1099-NEC make someone an independent contractor?
No. A form, contract, or business license does not control classification. The actual working relationship and the rules applied by each agency matter.
Does Washington use only the IRS worker test?
No. Federal tax, Washington unemployment insurance, workers’ compensation, and wage rules can apply different tests to the same relationship.
What should I document before putting a worker on payroll?
Document the role, duties, control, schedule, tools, expenses, and classification analysis. Then complete the required registrations and payroll setup before the first paycheck.
