Misclassifying workers is one of the most expensive compliance mistakes a small business can make — and it happens constantly. Not because business owners are trying to cut corners, but because most worker classification decisions are made based on what's convenient or what the worker prefers. That's understandable. It's also exactly what the IRS and Washington State don't care about.
If you regularly work with independent contractors, this post is for you. We've worked with clients across Puyallup and the South Puget Sound region on classification reviews and see the same misconceptions repeatedly. Here's what you actually need to know.
Why the Stakes Are Higher Than You Think
Independent contractor misclassification isn't just a paperwork problem — it carries real financial exposure. If a worker is reclassified as an employee, you can be on the hook for:
- Back payroll taxes — both the employee and employer shares, potentially going back three or more years
- IRS penalties and interest on those unpaid taxes
- Washington L&I back premiums for workers' compensation coverage that should have been in place
- Unemployment insurance liability to the Washington State Employment Security Department
- Wage claims from workers who may be owed overtime, benefits, or expense reimbursements
The IRS and Washington State both run compliance programs designed to catch misclassification. An audit triggered by one former contractor filing for unemployment can unravel your entire contractor workforce. Getting this right upfront costs a fraction of fixing it afterward.
The IRS Three-Factor Test: Behavioral Control, Financial Control, and Relationship
Behavioral Control
This factor asks who controls how the work gets done — not just what work gets done. If you tell a worker when to show up, how to do each task, what tools to use, and where to work, that's behavioral control consistent with an employment relationship. A true independent contractor controls their own methods and schedule.
Financial Control
This factor looks at the economic reality of the relationship. Independent contractors typically have a significant investment in their own equipment or tools, offer their services to multiple clients, have the ability to profit or lose money based on how they run their business, and invoice for specific projects rather than being paid a regular hourly wage. If a worker is economically dependent on you — one client, a steady paycheck, company-supplied tools — they start to look more like an employee under this factor.
Type of Relationship
This factor examines how you and the worker have structured things. Written contracts matter, but they're not the whole story. The IRS also looks at whether the relationship is permanent or indefinite, whether the work is central to your core business, and whether you provide benefits like insurance, vacation pay, or pension contributions.
Washington State Adds Another Layer: The ABC Test
Even if a worker passes the federal IRS test, Washington may still treat them as an employee for unemployment insurance and L&I purposes. Washington uses an ABC test for those determinations, and it's more demanding than the federal standard. Under the ABC test, a worker is presumed to be an employee unless you can demonstrate all three of the following:
- A: The worker is free from your direction and control in performing the work, both in practice and under any written agreement.
- B: The work performed is either outside your usual course of business, or performed outside all your places of business.
- C: The worker is customarily engaged in an independently established trade, occupation, or business.
Prong B trips up the most employers. If a construction company hires a framer, that work is clearly within the usual course of the business — so Prong B fails unless the framing happens entirely off-site. Failing it means L&I premiums and unemployment insurance obligations apply regardless of your federal classification.
The Myths That Keep Getting Business Owners in Trouble
These come up constantly. None of them hold up.
- 'They signed a contractor agreement.' A contract that calls someone a contractor doesn't make them one. Classification is based on the actual working relationship, not the label on paper.
- 'They want to be paid on a 1099.' A worker's preference for 1099 vs. W-2 treatment is irrelevant to how the law classifies them. Mutual preference isn't a legal defense.
- 'They have their own LLC.' Having a business entity doesn't automatically establish independent contractor status. The structure of the worker's business matters less than how the relationship actually functions.
The Industries Where This Shows Up Most
Worker classification problems tend to concentrate in certain sectors. Construction specialty subcontractors and laborers are among the most commonly misclassified workers in the country — Washington L&I pays close attention to this industry. Healthcare part-time practitioners and per-diem staff are frequently misclassified under arrangements that don't survive scrutiny. The cannabis industry in Washington has a well-documented problem with trimmers and delivery drivers brought on during peak seasons. Any business that cycles workers through temporary or project-based arrangements should conduct a classification review.
What to Do If You've Already Misclassified Workers
If you have some concern about your current situation, proactive correction is significantly better than being caught. The IRS Voluntary Classification Settlement Program (VCSP) allows eligible businesses to reclassify workers and settle past payroll tax obligations at a significant discount — typically around 10% of what would otherwise be owed. Washington State also has mechanisms for employers who come forward before an audit, and early engagement consistently produces better outcomes than a compliance finding.
The key is acting before someone files an unemployment claim or an auditor calls. At that point, your options narrow considerably.
How We Can Help
We work with small business owners across Puyallup and the broader South Puget Sound region to conduct formal worker classification reviews before problems develop. That means examining your actual working relationships, how work is directed and compensated, what your contracts say versus what's really happening, and how all of it holds up under both the IRS test and Washington's ABC test.
We help you document independent contractor relationships properly, structure agreements that reflect the actual nature of the work, and build a process so new workers are classified correctly from day one. If you have workers you're uncertain about — or you've been relying on any of the assumptions above — the right time to get clarity is now.
Frequently Asked Questions
What is the difference between a contractor vs. employee under IRS rules?
The IRS uses a three-factor test covering behavioral control, financial control, and the overall type of relationship. An employee is someone the business controls both in terms of what gets done and how it gets done. An independent contractor controls their own methods, serves multiple clients, and bears financial risk in their own business. The label on a contract doesn't determine the outcome — the actual working relationship does.
What is the ABC test for independent contractors in Washington State?
Washington State applies an ABC test for unemployment insurance and L&I purposes. To treat a worker as an independent contractor, you must show that the worker is free from your control, that the work is outside your usual course of business or done off your premises, and that the worker is customarily engaged in an independent trade or business. All three conditions must be met — this is stricter than the federal IRS test.
Can I call someone a 1099 worker if they agree to it?
No. A worker's agreement to be paid as a 1099 contractor doesn't determine their legal classification. The IRS and Washington State look at the actual working relationship — who controls the work, how the worker is compensated, and whether they operate as a truly independent business. Mutual agreement about tax treatment is not a legal defense against a misclassification finding.
What industries have the most independent contractor misclassification risk?
Construction, healthcare, cannabis, and businesses that rely on project-based or seasonal staffing carry the highest risk. Washington L&I focuses particularly on construction and cannabis. If your business uses contractors in any of these areas, a formal classification review is worth doing sooner rather than later.
What happens if I've been misclassifying workers and want to fix it?
Address it proactively. The IRS Voluntary Classification Settlement Program (VCSP) allows eligible businesses to reclassify workers and settle past payroll tax obligations at a significant discount — typically around 10% of what would otherwise be owed. Washington State also has options for employers who come forward before an audit. Act before a complaint or audit is triggered, when your options are still good.
