A self-employed individual who performs services for a company under a contract but isn't considered an employee, meaning the hiring company doesn't withhold taxes, provide benefits, or control how the work is performed.
Key Takeaways
The independent contractor relationship is straightforward in theory: a business hires someone to produce a specific result, and that person decides how to get it done. A company hires a graphic designer to create a logo. The company specifies what they want. The designer chooses the software, sets their own hours, works from their own studio, and delivers the finished product. That's contracting. The problems start when companies want the control of an employment relationship at the contractor cost structure. Telling a 'contractor' when to show up, what to wear, how to complete each task, providing them with equipment, and assigning them to work exclusively for your company looks like employment, regardless of what the contract says. The distinction matters because employees get protections that contractors don't: overtime pay, minimum wage, unemployment insurance, workers' compensation, anti-discrimination protections, FMLA leave, and employer-paid payroll taxes. Classifying someone as a contractor removes all of those obligations, which is why both the IRS and the Department of Labor scrutinize these arrangements closely.
The IRS evaluates the entire working relationship using three categories of evidence. Courts and agencies weigh all factors together rather than applying a simple checklist.
Does the company control how the worker does the job? Key questions: Does the company provide detailed instructions on how to perform the work (not just what result to achieve)? Does the company provide training on methods and procedures? Does the company dictate the worker's schedule, including when and where to work? Does the company specify what tools and equipment to use? If the company controls the process, not just the outcome, the worker looks more like an employee. A contractor who receives a project brief and delivers results is different from a worker who follows a procedures manual and reports to a supervisor daily.
Does the company control the business aspects of the worker's services? Key factors: Does the worker have unreimbursed business expenses? Does the worker invest in their own equipment, tools, and facilities? Does the worker offer services to the general public (not just one client)? How is the worker paid: by the project/deliverable (contractor) or by the hour/week/month (employee-like)? Can the worker realize a profit or loss from the engagement? A contractor who uses their own equipment, invoices for completed projects, serves multiple clients, and can profit or lose from the arrangement has financial independence. A worker who uses company equipment, receives a fixed weekly payment, and works for only one company does not.
How do the parties perceive the relationship? Evidence includes: Written contracts (though a contract calling someone a 'contractor' isn't conclusive). Whether the company provides employee-type benefits (health insurance, PTO, retirement plans). The permanency of the relationship (ongoing or project-based). Whether the worker's services are a key part of the company's regular business. An indefinite engagement where the contractor performs the company's core business functions looks like employment. A defined-scope project with a clear end date looks like contracting. The IRS places significant weight on whether the worker provides services integral to the company's main business.
Many states apply the ABC test, which is significantly harder for employers to satisfy. Under this test, a worker is an employee unless all three conditions are met.
| Prong | Requirement | What It Means in Practice | Common Failure Point |
|---|---|---|---|
| A: Free from control | The worker is free from the control and direction of the hiring entity in performing the work | The company can't dictate how, when, or where the work is done | Companies that set schedules, require on-site presence, or mandate specific processes |
| B: Outside usual course of business | The worker performs work outside the usual course of the hiring entity's business | A software company can hire a contractor for office cleaning, but not for software development | This is the strictest prong. Companies hiring contractors to do their core business work fail this test |
| C: Independently established | The worker is customarily engaged in an independently established trade, occupation, or business | The worker has their own business entity, markets services to multiple clients, and has an independent professional presence | Workers who depend on a single company for all their income and don't market services elsewhere |
This comparison covers the practical differences that affect payroll, taxes, legal liability, and day-to-day operations.
| Factor | Independent Contractor | Employee |
|---|---|---|
| Tax forms | 1099-NEC (income $600+) | W-2 |
| Tax withholding | None. Contractor pays own taxes | Employer withholds income tax, FICA (Social Security + Medicare) |
| Employer FICA cost | None | 7.65% of wages (6.2% SS + 1.45% Medicare) |
| Benefits | None required | Health insurance (ACA mandate for 50+ FTE), 401(k), PTO, workers' comp |
| Unemployment insurance | Not covered | Employer-funded state and federal (FUTA) |
| Work schedule | Set by contractor | Set by employer |
| Equipment | Contractor provides own | Employer provides |
| Termination | Per contract terms | Subject to employment law protections |
| IP ownership | Must be assigned via contract | Default belongs to employer (work for hire) |
| Training | Not typically provided | Employer provides onboarding and ongoing training |
A well-drafted contractor agreement protects both parties and supports proper classification. These clauses should appear in every independent contractor agreement.
The apparent savings of using contractors often drives the decision, but the true cost comparison must include compliance risk.
For a worker earning $80,000/year in total compensation: Employee cost: $80,000 salary + $6,120 employer FICA (7.65%) + $8,000 health insurance + $3,200 401(k) match (4%) + $1,600 workers' comp + $560 FUTA/SUTA = approximately $99,480/year. Contractor cost: $80,000 contracted amount + $0 payroll taxes + $0 benefits = $80,000/year. That's a $19,480 annual savings per worker, about 24%. But contractors often charge higher rates to cover their self-employment tax and benefits costs, so the real savings depend on the negotiated rate.
If a contractor is reclassified as an employee by the IRS or DOL, the company owes: back employment taxes (employer FICA share) for the entire period, penalties and interest on unpaid taxes, potential back benefits (health insurance, retirement contributions), overtime pay if the worker would have been non-exempt, state unemployment insurance premiums, and workers' compensation coverage. For a single misclassified worker over 3 years, the total exposure can exceed $50,000. Multiply that by 20 misclassified contractors, and you're looking at $1 million or more.
Use this checklist before, during, and after engaging any independent contractor.
