Contractor misclassification risk self-check
Answer 12 plain-English questions mapped to the three IRS common-law categories. The tool returns a heuristic Low, Medium, or High risk band, a category breakdown, and the specific factors leaning toward employee status. Built for US founders and finance teams.
This tool is a general heuristic for US companies to gauge misclassification risk. It is not tax or legal advice, and it does not produce a binding answer. The IRS itself says there is no magic or set number of factors that decides whether a worker is an employee or an independent contractor, and that all evidence of the degree of control and independence must be considered. See the IRS Independent Contractor or Employee page.
The Low, Medium, and High score bands in this tool are a heuristic chosen for the self-check, not an IRS rule. For a definitive determination, the firm or the worker can file IRS Form SS-8 or speak with a qualified tax professional.
Run the self-check
Twelve questions mapped to the three IRS common-law categories.
The IRS itself says there is no magic or set number of factors that decides whether a worker is an employee or an independent contractor. The scoring bands below are a heuristic chosen for this tool, not an IRS rule. For a definitive determination, file Form SS-8 with the IRS or speak with a qualified tax professional.
Behavioral control
Facts about whether your business has the right to direct and control how the worker does the task (instructions, training, supervision).
Do you set the worker's schedule or where they work?
Do you provide ongoing training on how to do the work?
Do you require the worker to follow specific procedures, tools, or methods?
Does someone on your team direct or supervise the worker day to day?
Financial control
Facts about whether your business has the right to direct or control the financial aspects of the worker's job (tools, expenses, method of payment, services available to the market).
Does the worker use their own equipment, tools, and software?
Do you reimburse the worker's business expenses?
Is the worker paid by the hour or a regular salary rather than by the project or deliverable?
Is the worker free to serve other clients while working for you?
Type of relationship
How the parties perceive their relationship: written contracts, employee-type benefits, permanency, and whether the services are a key activity of the business.
Has the engagement run more than 12 months or is it open-ended?
Does the worker work substantially full-time hours for you?
Do you provide employee-style benefits like paid time off, insurance, or retirement?
Is the worker's role a key, ongoing part of your business?
Most of your answers point to genuine independence. The arrangement looks contractor-like, but remember the IRS says there is no magic number of factors, so any single strong employee-like factor can still matter.
The bands above are a heuristic chosen for this tool. The IRS says there is no magic or set number of factors that decides worker status, so treat this as a starting point, not a verdict.
Misclassification can mean back federal employment taxes, IRS penalties, interest, and state-level exposure. There is a federal safe harbor known as Section 530 that can provide relief in some cases if you meet the reporting, substantive, and consistency tests. Read the full breakdown of misclassification penalties in the US and how the Section 530 safe harbor works.
The three IRS common-law categories
The IRS does not use a fixed scorecard. It uses three categories of evidence and weighs the whole picture.
Behavioral control
Behavioral control covers facts about whether your business has the right to direct and control how the worker does the task, including instructions on when, where, and how to work, the tools and equipment to use, the order or sequence of work, and ongoing training. Per the IRS Independent Contractor or Employee page, the more the business controls how the work is done, the more the worker looks like an employee.
Financial control
Financial control covers facts about whether the business has the right to direct or control the financial aspects of the worker's job, including significant investment, unreimbursed expenses, opportunity for profit or loss, whether the worker's services are available to the market, and the method of payment. Per the IRS Independent Contractor or Employee page, a real independent contractor has the chance to make a profit or take a loss, brings their own tools, and serves multiple clients.
Type of relationship
Type of relationship covers written contracts, employee-type benefits such as paid time off and insurance, the permanency of the relationship, and whether the services performed are a key activity of the business. Per the IRS Independent Contractor or Employee page, an open-ended engagement that delivers a core part of your business looks more like employment than a project-based contractor arrangement.
There is no magic number of factors
The IRS is explicit on this point: "There is no 'magic' or set number of factors that 'makes' the worker an employee or an independent contractor, and no one factor stands alone in making this determination." See the IRS Independent Contractor or Employee page. That is why the score bands in this tool are a starting point, not a verdict.
When you need a definitive answer: Form SS-8
For a binding determination, the firm or the worker can file Form SS-8, Determination of Worker Status for Purposes of Federal Employment Taxes and Income Tax Withholding. The IRS reviews the facts and issues a written determination. Read the full walk-through in our Form SS-8 worker status guide.

Pick the right path for this worker
If the engagement really is contractor-like, formalize it with a clean contract. If it really is an employee, run them on an EOR.
