The IRS does not use a fixed checklist or a magic number of factors to decide whether a worker is an employee or an independent contractor. Instead, the IRS weighs the entire working relationship against three categories: behavioral control, financial control, and the relationship of the parties. Get the classification wrong and the business can be held liable for employment taxes on that worker. That is why the analysis is worth doing before a 1099 goes out, not after.

What are the IRS criteria for classifying a worker as an employee or contractor?
The general rule is that a worker is an employee when the business can control what will be done and how it will be done. An independent contractor is someone in an independent trade, business, or profession who offers services to the public, according to the IRS.
The right to control is what matters, not whether the business actually exercises that control every day. A business can give a worker freedom of action and still have an employer-employee relationship if the right to direct the work exists.
The determination rests on the full relationship, sorted into three categories: behavioral control, financial control, and the relationship of the parties. The IRS states that no single factor decides the outcome, and there is no set number of factors that makes a worker one or the other. If an employer-employee relationship exists in substance, the label on the contract does not change it.
What does behavioral control look like in practice?
Behavioral control asks whether the business controls, or has the right to control, what the worker does and how the job gets done. The IRS identifies instructions on when and where to work, training, and required procedures or methods as signals of behavioral control.
Remote work does not change the test. A worker who chooses to work from home is still an employee under common-law rules if the business controls what will be done and how it will be done, according to the IRS.
The question is the degree of control over the work itself, not the worker's location or schedule preference. A business that requires specific software, detailed reporting, or approval at set stages is exercising behavioral control. A business that only specifies the result and leaves the method to the worker is not.
What does financial control look like in practice?
Financial control asks whether the business directs the financial and business aspects of the work. Key markers include how the worker is paid, whether expenses are reimbursed, and who provides tools and supplies, according to the IRS.
Whether the worker can realize a profit or loss, and whether they offer services to other businesses, both bear on the analysis. A contractor who sets their own rates, buys their own equipment, and works for multiple clients shows financial independence.
A contractor carries their own business expenses and deducts them on their own return, typically on Schedule C (Form 1040), according to Brady Ware. An employee generally has expenses reimbursed and does not bear the risk of loss on the job.
How does the relationship between the parties affect classification?
The relationship category looks at written contracts, employee-type benefits such as pension, insurance, and vacation pay, and how long the relationship is expected to last. The IRS weighs this evidence alongside behavioral and financial control.
A contract that calls someone a contractor is evidence, but it is not decisive on its own. The IRS states that all information providing evidence of the degree of control and independence must be considered.
Regular, ongoing work that is central to the business points toward employment. A defined project with a clear end points the other way. No clause in an agreement settles the question by itself, because the substance of the working relationship controls.
What is the difference between a W-2 employee and a 1099-NEC contractor?
For employees, the business withholds income tax plus Social Security and Medicare taxes, pays the matching employer share, pays federal and state unemployment taxes, and issues Form W-2. The IRS confirms these obligations apply to wages paid to an employee.
For independent contractors paid $600 or more in a year, the business generally issues Form 1099-NEC and withholds nothing. The IRS states that payments to independent contractors are reported on Form 1099-NEC in box 1.
Contractors pay self-employment tax, which covers Social Security and Medicare, plus income tax, and typically make estimated quarterly payments. According to Brady Ware, independent contractors generally do not receive employer-sponsored benefits and arrange their own health coverage and retirement plans.
What happens if a business gets worker classification wrong?
Misclassification means the employer's share of taxes was never paid and the worker's share was never withheld. The IRS states that a business can be held liable for employment taxes for that worker.
Workers who believe they were misclassified can request a determination of worker status from the IRS. A worker who receives a determination can use Form 8919 to figure and report their share of uncollected Social Security and Medicare taxes, according to the IRS.
The IRS offers the Voluntary Classification Settlement Program, an optional program that lets a business reclassify workers as employees for future employment tax purposes. A business applies by filing Form 8952 and entering into a closing agreement with the IRS, as described by the IRS.
How do you document a contractor classification so it holds up?
Keep the written agreement, invoices, payment records, and Form 1099-NEC filings together so the working relationship can be described accurately if questions come up. The IRS considers all information that provides evidence of control and independence.
Document the business reasons the worker operates independently: their own tools, their own customers, their own profit or loss. A contractor who invoices from a separate business entity and markets services to the public has a stronger independent position.
Avoid treating a contractor like an employee day to day. Set schedules, required training, and reimbursed expenses undercut the classification, according to the IRS. Confirm the current-year filing and reporting dates each year, since they shift from year to year.
When is it worth bringing in a specialist for multi-state contractor questions?
A worker's location, the states they perform services in, and where the business operates can each pull the analysis in a different direction, and state tests do not always match the federal one. The IRS framework is federal, but state agencies apply their own standards.
