One Client on a 1099: Self-Employed or Misclassified?

Updated May 6, 2026 · 8 min read

You sign a contract with one company, work 40 hours a week for them, and they pay you on a 1099-NEC instead of a W-2. Are you actually self-employed, or are you a misclassified employee paying 7.65% more in tax than you should be? In 2026 the answer depends on which test applies — federal IRS, state ABC test, or the Department of Labor's economic reality test — and they don't all agree.

The short answer

One client doesn't automatically mean you're misclassified, but it's a strong signal. Three things matter:

1. Behavioral control — does the company tell you when, where, and how to work?
2. Financial control — do you have a real business (other clients, your own tools, profit/loss exposure)?
3. Relationship type — written contract, benefits, indefinite duration, integral to the business?

If "yes" to most behavioral and relationship questions, and "no" to financial, you may be a misclassified employee. The financial cost: as a 1099 you pay both halves of FICA (15.3%) instead of just the employee half (7.65%). That's $4,500 a year on $60k of income.

The IRS 20-factor test (federal)

The IRS uses a multi-factor test condensed into 3 categories. The factors that most often distinguish employees from contractors:

• Instructions: Employee receives detailed instructions; contractor controls the means.
• Training: Employer trains employees; contractors arrive trained.
• Set hours: Employees have set hours; contractors set their own.
• Continuing relationship: Indefinite = employee-like; project-based = contractor-like.
• Tools and equipment: Employer provides for employees; contractors bring their own.
• Payment method: Hourly/salary regular cadence = employee; per-project invoicing = contractor.
• Working for multiple firms: Single client at a time = employee-like; multiple clients = contractor.
• Realization of profit or loss: Contractor can profit or lose; employee just earns wages.

No single factor is determinative. The IRS weighs them as a whole. Most "1099 long-term single-client engagements" lean employee on 5+ of these.

The state ABC test

California, Massachusetts, New Jersey, and a growing list of states use a stricter ABC test (codified in California's AB 5). To be a contractor, ALL three must be true:

1. A: The worker is free from control and direction of the hiring entity.
2. B: The worker performs work outside the usual course of the hiring entity's business.
3. C: The worker is engaged in an independently established trade, occupation, or business.

The B prong is brutal for one-client situations. If you're a developer working full-time on the only product a software company sells, you fail B and the company fails the test — you're an employee under California law. Many tech 1099 contracts in CA quietly violate this and get challenged after termination via EDD wage claims.

The DOL economic reality test (federal labor law)

The 2024 Department of Labor rule (effective March 2024, still in force as of 2026) restored a six-factor "economic reality" test for FLSA classification. It looks at:

• Worker's opportunity for profit/loss based on managerial skill
• Investments by worker and employer
• Permanence of the relationship
• Control over the work
• Whether work is integral to the business
• Skill and initiative

This test governs minimum wage, overtime, and some benefits — not federal tax. But getting reclassified under DOL rules often cascades into IRS reclassification.

If you think you're misclassified, what to do

1. File Form SS-8 — request the IRS determine your worker status. Long process (6+ months) but binding.
2. File Form 8919 — pay only the employee half of FICA when filing your taxes, attaching your SS-8 case number. The IRS goes after the employer for their half.
3. State labor board complaint — for state classification disputes (California EDD, NY DOL, etc.).
4. Stay quiet, file as 1099, find more clients — many freelancers conclude that opening a misclassification case kills the relationship. If the income is good and the engagement is short-term, this is a pragmatic choice.

If you're going to keep filing as 1099 anyway, treat the income as self-employment income, pay quarterly estimated taxes, and at least take the deductions a contractor is entitled to (home office, equipment, internet — see our deductions checklist).

What lowers misclassification risk for both sides

• Multiple clients — ideally three or more, with documented pitches and active prospecting.
• Your own LLC — invoice from a registered business entity, not your personal name. See LLC vs sole proprietor.
• Your own equipment — laptop, software subscriptions paid by you, not the client.
• Project-based contracts with deliverables and end dates, not "ongoing engagement."
• Set your own hours — at least nominally; document this in the contract.
• Insurance — professional liability or E&O policy is a strong signal of independent business.
• Marketing — a website, business cards, public freelance presence.

The accidental S-corp upgrade path

If you've genuinely got one client but are doing $150k+ of contracted work with full freelancer freedom (set your own hours, own equipment, no benefits, project deliverables), forming an LLC and electing S-corp can make the structure cleaner:

• The client pays your LLC, not you personally.
• Your LLC pays you a W-2 salary (reasonable comp) plus distributions.
• Reduces SE tax exposure on the distribution portion.
• Adds a layer of separation that helps the misclassification analysis.

See our S-corp election guide — it's worth running the numbers above ~$120k net SE income.

FAQs

Is having one client illegal? No. Many real freelancers have one big client at a time. The question is whether the relationship has employee characteristics — control, indefinite duration, integral work, no other clients — not just count.

Can I be a contractor in one state and an employee in another for the same role? Yes. The IRS may accept your 1099 status while California's EDD considers you misclassified. Each test is independent.

What if my "one client" is a staffing agency? Different analysis. Staffing agencies sometimes legitimately use 1099 for placement work, but most W-2 their workers. If you're billed via a staffing platform, you usually have a clearer 1099 status.

Does signing an "Independent Contractor Agreement" make me a contractor? No. Both the IRS and state labor boards look past the contract label to the actual working relationship. A "contractor" agreement with W-2-style behavior is still a misclassified employee under the law.

How long until I should worry about misclassification? If a single 1099 engagement runs more than 12 months, with set hours and the company providing tools, the risk is high. Short-term project work (3-6 months, deliverable-based) is low risk regardless of count.

What if I want to be an employee instead? Tell the company. Many will convert you to W-2 if asked, especially in jurisdictions where misclassification penalties are aggressive (CA, NJ). Just be aware your take-home will drop ~7.65% from the loss of the employer-paid FICA half — but you also stop paying it yourself.
