Independent Contractor

An independent contractor is someone who performs services for another party while remaining in business for themselves, so that the hiring party controls the result of the work rather than the means and methods of accomplishing it. Publication 15-A states that general rule in almost those words. Three nearby terms are often used as if they were the same thing and are not, which is worth settling before going further. Independent contractor is a classification, the answer to whether a worker is an employee. Self-employment is the tax consequence that follows from not being an employee, and it is broader, reaching partners and business owners who are nobody's contractor. A sole proprietorship is the legal form of the business itself, and most independent contractors are sole proprietors without ever filing anything to become one. A single person is routinely all three at once, which is why the words get used interchangeably even though each answers a different question.

The IRS test is three categories of evidence, and it turns on the right to control rather than its exercise. Publication 15-A puts it this way: "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." Behavioral control asks whether the business can direct when, where and how the work is done, including what tools to use and in what sequence, and whether it trains the worker in its own methods. Financial control asks about unreimbursed expenses, investment in facilities or tools, whether the worker offers services to the wider market, how payment is structured, and whether the worker can realise a profit or a loss. The type of relationship asks about written contracts, benefits, the permanence of the arrangement, and whether the services are a key activity of the business.

The decisive word in the common-law rule is "right." Publication 15-A says a worker is generally an employee if the business has the right to control what will be done and how it will be done, and adds that this is so "even when you give the employee freedom of action." A hands-off employer with the authority to intervene still has an employee.

What happened to the twenty factors. Revenue Ruling 87-41 set out a twenty-factor list that a great deal of published guidance still presents as the IRS test. It appears nowhere in Publication 15-A or on the IRS's current classification pages, and the agency now organises the same common-law inquiry into the three categories above. The ruling was never formally revoked, so courts and practitioners still cite it, and the accurate statement is that the twenty factors are historical framing for a test that has not itself changed rather than a list that has been repudiated.

The binary is wrong: there are four federal categories. Publication 15-A opens by saying the person performing the services may be an independent contractor, a common-law employee, a statutory employee, or a statutory nonemployee. The last category matters because no control test is applied to it. Statutory nonemployees are direct sellers, licensed real estate agents, and certain companion sitters, and the first two are treated as self-employed for all federal tax purposes if substantially all payments for their services relate to sales or other output rather than to hours worked, and the services are performed under a written contract providing that they will not be treated as employees. A licensed real estate agent meeting those conditions is therefore self-employed by operation of statute, whatever a control analysis would have concluded. At the other end, a statutory employee is treated as an employee for certain employment taxes despite not being one under common law, and is flagged in box 13 of Form W-2.

Federal wage and hour law has three separate answers as of mid-2026, and collapsing them into one is the commonest error in published guidance. Take them in order. The regulation on the books is 29 CFR part 795 as amended by a final rule published in January 2024. No court has vacated or enjoined it. Five lawsuits were filed against it, and according to the Department's own later rulemaking each lawsuit remains pending and each has been stayed on the Department's representation that it intends to reconsider the rule. The agency's enforcement posture is different: Field Assistance Bulletin 2025-1, issued in May 2025, directs that the Wage and Hour Division "will no longer apply the 2024 Rule's analysis when determining employee versus independent contractor status in FLSA investigations," and sends investigators to earlier guidance instead. The same bulletin preserves the rule for everyone else, stating that until further action is taken "the 2024 Rule remains in effect for purposes of private litigation and nothing in this FAB changes the rights of employees or responsibilities of employers under the FLSA." And the proposed replacement is only proposed. A notice of proposed rulemaking published in February 2026 would rescind part 795 and restore the analysis adopted in a January 2021 final rule with modifications, and would extend it to the Family and Medical Leave Act and the Migrant and Seasonal Agricultural Worker Protection Act. Its comment period closed in April 2026 and no final rule has been issued.

So a page saying the rule was rescinded is wrong, and a page saying the Department applies it is also wrong. The factor sets differ too, and should not be blended. The 2024 rule identifies six factors as tools or guides in a totality-of-the-circumstances analysis with no factor or subset necessarily dispositive: the opportunity for profit or loss depending on managerial skill, investments by the worker and the potential employer, the degree of permanence of the relationship, the nature and degree of control, the extent to which the work is an integral part of the potential employer's business, and skill and initiative. The proposed replacement would elevate two of those, control and opportunity for profit or loss, above three others.

State law is a third regime and it has no federal analogue. California Labor Code section 2775(b)(1) presumes a worker is an employee unless the hiring entity shows all three of the following: that the person is free from the control and direction of the hiring entity in connection with the performance of the work, both under the contract and in fact; that the person performs work outside the usual course of the hiring entity's business; and that the person is customarily engaged in an independently established trade, occupation or business of the same nature as the work performed. The middle prong is the one that reclassifies most workers and it has no counterpart in either federal test, since a worker can be entirely free of control and still be doing the hiring entity's core work. Section 2775(b)(3) preserves an earlier multifactor standard as a fallback where the three-part test is held inapplicable, and a long list of occupational exemptions sits alongside it. That is California's rule, not the country's. Other states use their own variants, some narrower and some limited to particular statutes, so the state question has to be asked state by state.

The reliefs and procedures a business has. A business that treated a worker as a contractor and got it wrong may still avoid employment tax liability under a long-standing relief provision, commonly called section 530 relief after the 1978 act that created it. Publication 15-A describes the conditions: a reasonable basis for not treating the worker as an employee, all required federal information returns filed consistently with that treatment, and no worker in a substantially similar position treated as an employee by the business or a predecessor for any period beginning after 1977. The relief does not reach a technical service specialist supplied to another business under an arrangement between two businesses, which Publication 15-A defines as an engineer, designer, drafter, computer programmer, systems analyst or similarly skilled worker. A business that wants to reclassify workers going forward can also apply to the Voluntary Classification Settlement Program.

A worker or a business that wants an official answer can file Form SS-8 and ask the IRS to determine the status. It is a real remedy with a real drawback: the IRS warns that it may take at least six months to receive a determination, which makes it a poor tool for an urgent problem, and it answers the federal tax question only.

A classification question gets answered the same way each time. Identify who is asking, because that fixes which test applies: the IRS for federal employment and income tax, the Department of Labor for federal minimum wage and overtime, a state agency for state wage law, unemployment insurance and workers' compensation, and a court if the matter is litigated. Then apply that authority's own factors to how the work is actually performed rather than to what the paperwork says. Expect the possibility that two authorities reach opposite answers about one worker, because the tests were written for different purposes and weigh different things.

A hypothetical example of the one consequence that is pure arithmetic. Tomas is paid $80,000 over a year for the same work under two different classifications. Treated as an employee, 7.65% of his wages comes out of his pay for Social Security and Medicare, which is $6,120, and the employer pays a matching $6,120 that never touches his return. Treated as an independent contractor, both halves are his. If the work carries $5,000 of deductible business expenses, his net profit is $75,000, his net earnings from self-employment are 92.35% of that, or $69,262.50, and self-employment tax at 15.3% comes to $10,597.16, of which half, $5,298.58, is deductible above the line. So the classification alone moves roughly $4,477 of payroll tax onto him before the deduction and any income tax effect, and it does so without changing a thing about the work itself.

The full computation of that tax, the $400 filing floor and the estimated payments that replace withholding all belong to self-employment and to self-employment tax. The point here is narrower: what the classification decides is which column a worker is in, and the money follows the classification rather than the job description.

What contractor status offers a worker

• Control over how, when and often where the work gets done, which is the same freedom the legal tests treat as evidence of the status.
• Genuine business expenses come off before tax, so tax attaches to profit rather than to gross receipts.
• Multiple clients rather than one employer, which spreads the risk of losing any single source of income.
• Access to retirement plans built for people without employees, which allow far larger contributions than an individual retirement arrangement alone.

What it costs, and where the risks sit

• Federal minimum wage and overtime protections attach to employees, so a contractor generally has neither.
• Unemployment insurance and workers' compensation systems are built around employment, and whether either reaches a contractor is a state-by-state question rather than a federal one.
• Both halves of Social Security and Medicare tax fall on the worker, and nothing is withheld, so estimated payments and the record-keeping behind them are the worker's own responsibility.
• No employer-provided health coverage, retirement match or paid leave rides along with the work.
• The status is not settled by agreement, so a worker who has signed a contractor agreement may still be an employee under one or more of the tests, and a business that got it wrong may have a relief provision available even where the classification was incorrect.
