Classification Risk Checker
This assessment is organised around the three categories of evidence the IRS actually uses in Publication 15-A: behavioral control, financial control, and the type of relationship of the parties. The weighting across the 15 questions is ours, not the IRS's, and is a judgement about which facts tend to carry the most weight in practice. Answer all 15 questions for your risk score.
Does the company dictate specific work hours or require the worker to be available during set times?
Does the company provide detailed instructions on how to perform the work (not just what to deliver)?
Does the company provide training on its methods, systems, or procedures?
Does the company evaluate the worker's performance based on daily or weekly activities rather than project outcomes?
Does the company provide the primary tools, equipment, or software the worker uses?
Does the company reimburse the worker's business expenses (office space, travel, supplies)?
Is the worker paid a fixed salary or hourly rate regardless of output?
Is the worker prohibited from offering similar services to other clients?
Does the worker receive benefits such as health insurance, retirement contributions, or paid time off?
Is the relationship ongoing and indefinite rather than project-based with a defined end date?
Does the worker perform the same type of work as the company's regular employees?
Can the company terminate the worker at will, without adhering to contract termination provisions?
Does the worker perform services on the company's premises as a regular requirement?
Does the company require the worker to submit regular time reports or activity logs?
Is the worker restricted from hiring their own assistants or subcontractors?
IRS 3-Category Test Explained
Publication 15-A states it plainly: "Facts that provide evidence of the degree of control and independence fall into three categories: behavioral control, financial control, and the type of relationship of the parties." No single fact is decisive; the IRS weighs the whole relationship.
On the "IRS 20-factor test"
You will see a great deal of guidance describing a 20-factor IRS test, usually citing Revenue Ruling 87-41, and often describing the three categories above as a regrouping of those 20 factors. They are not the same framework. Publication 15-A does not mention a 20-factor test or Revenue Ruling 87-41 at all; it does not use a numbered-factor approach. The twenty factors are a 1987 revenue ruling that remains on the books as an interpretation of the common-law test, but the categories below are what the IRS publishes today, and they are what the examples in its own guidance are organised around. Treating the three categories as a tidy repackaging of twenty numbered factors gives a false impression of precision; the factors listed under each heading here are illustrative, not a checklist with a score attached.
1.Behavioral Control
Does the company control how the worker does their job? This is often the most important category.
Instructions: Does the company tell the worker when, where, and how to work? Employees receive detailed procedures. Contractors receive specifications and deadlines.
Training: Does the company train the worker on its methods? Training suggests behavioral control. Contractors are hired because they already have the expertise.
Evaluation: Is the company measuring results or methods? Evaluating deliverable quality supports contractor status. Monitoring daily activities suggests employment.
Work sequence: Does the company set the order of operations? Employees follow prescribed processes. Contractors determine their own methods.
Location and hours: Does the company require the worker to be at a specific location during specific hours? This is a strong indicator of behavioral control.
2.Financial Control
Does the company control the business aspects of the worker's activities?
Investment: Does the worker invest in their own tools, equipment, and facilities? The IRS looks for a significant investment, but deliberately sets no dollar threshold, and notes that there are no precise dollar limits for what counts.
Unreimbursed expenses: Does the worker bear their own business expenses? Contractors pay for their own software, insurance, marketing, and office space.
Profit or loss opportunity: Can the worker earn a profit or suffer a loss? Contractors set their own rates and manage their margins. Employees receive fixed compensation.
Market availability: Does the worker offer services to the general market? Contractors typically have multiple clients, a website, and their own business identity.
Payment method: Is the worker paid per project or per time period? Project-based payment supports contractor status. Regular salary payments suggest employment.
3.Type of Relationship
What is the nature of the arrangement between the parties?
Written contract: Does a contract exist that defines the relationship? A well-drafted contractor agreement establishes intent, though it is not dispositive on its own.
Benefits: Does the company provide employee-type benefits? Health insurance, retirement contributions, and paid leave are strong indicators of employment.
Permanency: Is the relationship ongoing and indefinite? Project-based engagements with defined end dates support contractor status.
Key services: Is the work a core business activity? If the contractor does the same work as your employees, classification risk increases significantly.
Discharge/termination: Can the company terminate the worker without following contract provisions? At-will termination is an employee characteristic.
Federal Misclassification Penalties
If the IRS determines a worker was misclassified, penalties depend on whether you filed 1099s and whether the misclassification was intentional.
| Scenario | Penalty |
|---|---|
| 1099 filed, reasonable basis for classification | 1.5% of wages + 20% of employee's FICA |
| No 1099 filed | 3% of wages + 40% of employee's FICA |
| Intentional misclassification | Full employer FICA + income tax that should have been withheld + penalties + interest |
| DOL enforcement (FLSA) | Back wages + overtime + liquidated damages (up to 2x back wages) |
| VCSP voluntary correction | 10% of the liability computed at the reduced section 3509(a) rates (no interest, no penalties) |
California ABC Test (AB5)
California's ABC test is the strictest state classification test. Under AB5, a worker is presumed to be an employee unless the hiring entity proves ALL three prongs.
Prong A:Free from control and direction
The worker must be free from the control and direction of the hiring entity in performing the work, both under the contract and in fact. This is similar to the federal behavioral control test.
Prong B:Outside the usual course of business
The worker must perform work that is outside the usual course of the hiring entity's business. This is the hardest prong to satisfy. A software company hiring a freelance developer often fails prong B because software development IS the company's core business.
Prong C:Independently established trade
The worker must be customarily engaged in an independently established trade, occupation, or business of the same nature as the work performed. The worker should have their own business entity, website, other clients, and independent marketing.
AB2257 exempts certain professions (lawyers, doctors, accountants, engineers, real estate agents) from the ABC test, applying the more flexible Borello test instead. See our state rules page for full details.
Voluntary Classification Settlement Program (VCSP)
If you have been misclassifying workers and want to correct it, the IRS VCSP lets you reclassify workers prospectively with significantly reduced penalties.
VCSP Benefits
- Pay 10% of the employment tax liability that would have been due on compensation paid to the workers for the most recent tax year, determined under the reduced rates of section 3509(a). The reduced rates matter: they are what make the figure small, and a 10% calculation at full rates would be a materially larger number
- No interest or penalties on the payment
- No employment tax audit of prior years with respect to the worker classification
- Prospective reclassification only (no retroactive liability)
Eligibility Requirements
- You must have consistently treated the workers to be reclassified as independent contractors or other non-employees, including having filed all required Forms 1099 for them for the previous three years. This is the requirement that most often disqualifies a business that has been informal about 1099s
- You cannot currently be under employment tax audit by the IRS
- You must not be under DOL or state agency audit concerning worker classification
- If you were previously audited on worker classification, you must have complied with the result and not be contesting the classification in court
- Apply on Form 8952 (Application for Voluntary Classification Settlement Program) at least 120 days before the date you want the reclassification to start, so this is not a route you can take in the week you discover the problem
VCSP terms above are from the IRS Voluntary Classification Settlement Program page (originally Announcement 2011-64, as modified in 2012), checked 1 October 2026. The programme was open as at that date.
Notable Misclassification Cases
Alexander v. FedEx Ground
Ninth Circuit 2014, $228m settled 2016FedEx classified delivery drivers as independent contractors while controlling their routes, schedules, uniforms, and vehicles. In August 2014 the Ninth Circuit held that the California drivers were employees under the state's right-to-control test. The $228 million settlement of the California class claims came later, agreed in June 2016. The two dates are routinely merged into one in secondary write-ups, which is worth knowing if you are checking the figure.
Vizcaino v. Microsoft (the permatemp case)
Ninth Circuit 1997, ~$97m settled 2000One case, often written up as two. Microsoft used long-term 'permatemps' who worked alongside regular employees performing identical work, but were classified as contractors and denied benefits. The Ninth Circuit held in 1997 that they were common-law employees entitled to participate in Microsoft's stock purchase plan; the case settled for roughly $97 million in December 2000. The principle it is cited for is that workers performing the same duties as employees, in the same manner, at the same location, are employees regardless of the contract label.
Uber and Lyft (California)
Prop 22 upheld 2024California's AB5 reclassified rideshare drivers as employees. Uber, Lyft, and DoorDash spent over $200 million backing Proposition 22, which created a carveout for app-based drivers. On July 25, 2024, the California Supreme Court unanimously upheld Prop 22 as constitutional in Castellanos v. State of California, so app-based drivers remain independent contractors in California.
Uber and Lyft (Massachusetts, 2024)
$175 millionThe Massachusetts Attorney General settled multi-year misclassification litigation against both companies in July 2024. Per the AG's 2025 Labor Day Report, the companies paid a combined $175 million to the state in 2025, with $145 million distributed to current and former drivers. Drivers also became entitled to a per-hour minimum, paid sick leave and a healthcare stipend. This is the single largest misclassification recovery in the Commonwealth's history and a useful counterweight to the California outcome above: the same business model produced opposite results in two states.
