Worker Classification

Why classification matters

The employee vs contractor question decides almost every obligation an employer has. For employees, the company withholds income tax, pays the employer share of Social Security and Medicare (FICA) and federal and state unemployment taxes, provides workers' compensation coverage, pays minimum wage and overtime under the FLSA, and offers benefits under its plans and the ACA employer mandate. Employees are also protected by anti-discrimination, leave and safety laws.

Independent contractors get almost none of that. They are paid on invoices, receive a Form 1099-NEC if paid $600 or more in the year (the threshold rises to $2,000 for payments made from 2026), pay self-employment tax themselves and buy their own insurance.

The cost difference is usually 20% to 35% of pay, which is why misclassification is tempting and why regulators focus on it. A contractor label does not change the legal relationship. If the work looks like employment, the law treats it as employment.

The three tests you need to know

There is no single test. Different agencies and laws use different ones, and a worker can be an employee under one and a contractor under another.

IRS common-law test. For federal tax purposes, the IRS looks at the degree of control and independence in three categories:

• Behavioral control: does the company control or have the right to control what the worker does and how?
• Financial control: does the company control the business side of the work, such as how the worker is paid, whether expenses are reimbursed and who provides tools?
• Relationship of the parties: are there written contracts, benefits, an expectation that the relationship will continue, and is the work a key activity of the business?

Either party can file Form SS-8 to ask the IRS for a determination.

FLSA economic reality test. For minimum wage and overtime, courts ask whether the worker is economically dependent on the business or truly in business for themselves. Factors include opportunity for profit or loss based on managerial skill, investment, permanence of the relationship, the nature and degree of control, whether the work is integral to the business, and skill and initiative. The Department of Labor's guidance has changed with each administration: a 2024 rule adopted a six-factor totality test, and in May 2025 the DOL announced it would stop applying that rule in its own investigations and return to earlier guidance while it reconsidered. Courts apply their own circuit's version of the test either way.

[ABC test](/glossary/abc-test/). Used by California (AB5, 2019, codifying the Dynamex decision), Massachusetts, New Jersey and others for some or all state laws. A worker is an employee unless the business proves all three: (A) the worker is free from the company's control and direction, (B) the work is outside the usual course of the company's business, and (C) the worker is customarily engaged in an independently established trade or business of the same kind. Prong B is the one most businesses cannot meet. A contact center that hires 1099 agents to answer its clients' customer calls fails it, because answering customer calls is the business.

Common misclassification risks in hiring and staffing

In our experience, these are the patterns that cause the most trouble:

• Work-at-home agents paid as contractors. They follow scripts, log into the company's systems, work assigned schedules and are monitored by quality teams. That is control, and under most tests they are employees.
• Long-term contractors doing core work. A recruiter on a 1099 for three years, working full-time hours on the company's requisitions with a company email address, looks like an employee.
• Converting employees to contractors for the same work after a layoff.
• Trainers and coaches paid per class who are told when, where and how to deliver the content.
• Gig-style shift work booked through an app, where the business sets rates and can deactivate workers. Status depends heavily on state law; California's Proposition 22 created a special category for app-based drivers only.

When a third party is involved, such as a staffing agency, PEO or employer of record, the worker is usually the W-2 employee of that firm, but the client can still be a joint employer for wage, discrimination and safety purposes if it controls the work.

What misclassification costs

When a worker is reclassified as an employee, the employer can owe:

• Back wages, including overtime for every week over 40 hours, plus equal liquidated damages under the FLSA.
• Unpaid employer FICA and federal and state unemployment taxes, plus a portion of the income tax and employee FICA that should have been withheld, with interest and penalties.
• State penalties. California, for example, imposes civil penalties of $5,000 to $25,000 per violation for willful misclassification.
• Retroactive benefits eligibility, such as 401(k) contributions and health coverage, and possible ACA employer mandate penalties.
• Workers' compensation premiums and liability for uninsured injuries.

The IRS Voluntary Classification Settlement Program lets employers reclassify workers going forward and pay a reduced amount on past federal employment taxes, if they meet eligibility rules. Section 530 relief can protect employers that had a reasonable basis for contractor treatment and consistently treated similar workers the same way.

How to classify workers correctly

1. Start with the work, not the budget. Ask whether the task is part of the core business and whether you need to control how it is done. If yes to both, plan for employees or a staffing firm.
2. Apply the strictest test that applies. For a multi-state workforce, that often means the ABC test in California, Massachusetts or New Jersey.
3. Check the real relationship. Who sets hours? Who provides equipment? Can the worker turn down work, hire helpers, or work for competitors? Do they invoice, carry insurance and market themselves?
4. Write a contract that matches reality, but do not rely on it. A contract saying independent contractor carries little weight if the facts say otherwise.
5. Keep contractors out of employee processes. No performance reviews, required training, company email titles or manager hierarchies.
6. Review annually. Relationships drift. A three-month project contractor who is still there in year two needs a fresh look.

Worker classification is separate from exempt vs non-exempt status. First decide employee or contractor; only employees are then classified as exempt or non-exempt. Many organizations manage contractors as part of a wider contingent workforce program, and the gig economy has made this one of the most litigated areas of employment law. Rules vary sharply by state and by country, so get advice before converting a group of roles.
