Calling a worker an independent contractor does not make them one. That is the hard lesson behind Illinois’ Employee Classification Act, a statute that has quietly created serious liability for businesses — especially in construction — that treat workers as contractors when the law considers them employees. Gaurav Mohindra regularly sees businesses focus on the paperwork, such as a signed contractor agreement and a Form 1099, while overlooking the reality of the working relationship, which is what regulators and courts actually examine.
The Employee Classification Act, codified at 820 ILCS 185, applies most prominently to the construction industry in Illinois. It presumes that an individual performing services for a construction contractor is an employee unless the business can prove otherwise. That presumption, and the demanding tests behind it, flip the burden in a way many companies do not realize until an investigation or lawsuit arrives.
The Tests Illinois Actually Applies
Under the Employee Classification Act, an individual performing construction services is treated as an employee unless the engaging business demonstrates that the individual is free from control and direction over the performance of the work, and that the individual qualifies as a legitimate independent contractor or bona fide sole proprietor or partnership under the statute’s requirements. Among other things, the business must show that the worker operates a separate and distinct business, holds the requisite licenses or registrations, controls the manner and means of the work, bears the risk of profit or loss, and offers services to the public or other businesses rather than depending on one source of work.
Separate from that statute, the Illinois Unemployment Insurance Act applies its own well-known ABC test for whether services constitute employment for unemployment tax purposes. Under Section 212 of that Act, services are treated as employment unless the individual is free from control and direction, the work is outside the usual course of the employer’s business or performed away from its locations, and the individual is engaged in an independently established trade or business. Failing any one prong can be enough to make the worker an employee for that purpose.
“A contractor agreement is evidence of the relationship, not the definition of it. Agencies look at who controls the work, whose business the work serves, and whether the worker truly runs a separate enterprise,” says Gaurav Mohindra.
Where the Real Money Exposure Sits
Misclassification exposure is rarely a single bill. It tends to arrive in layers. At the state level, the Illinois Department of Labor enforces the Employee Classification Act, and violations can bring civil penalties assessed per violation and per day, along with liability for the value of unpaid contributions, taxes, and benefits the worker should have received. Private lawsuits are also possible, including class actions, which can multiply a modest per-worker problem into a company-threatening number.
Beyond that statute, a misclassification finding tends to travel. The Illinois Department of Employment Security may assess unpaid unemployment insurance contributions with interest and penalties. The Illinois Department of Revenue may pursue unpaid withholding. At the federal level, the Internal Revenue Service and the U.S. Department of Labor apply their own worker-status analyses, raising risks around employment taxes and unpaid overtime under the Fair Labor Standards Act. And when an injured worker who was labeled a contractor turns out to have no workers compensation coverage in place, a workplace accident can become the most expensive classification mistake of all.
“Businesses often think the savings from using contractors is the wage difference. The real comparison is between paying employment costs upfront and paying penalties, back taxes, back wages, and legal fees all at once, years later,” says Gaurav Mohindra.
Habits That Create the Problem
Most misclassification cases do not begin as deliberate schemes. They begin as habits. A company brings on a worker as a contractor during a busy season and never revisits the arrangement. The worker is given a schedule, company tools, a company shirt, and instructions from a supervisor, and works nowhere else. The agreement says contractor; every fact on the ground says employee. Over time, headcount grows on the same flawed template, and so does the liability.
Seasonal demand, project-based work, and genuine specialty trades can all support legitimate contractor relationships. The distinction is not whether the arrangement is convenient but whether the worker genuinely operates an independent business: separate clients, separate insurance, control over how the job is done, and the entrepreneurial risk that goes with it.
A Hypothetical: Consider a Suburban Remodeling Company
Consider a hypothetical remodeling company in the Chicago suburbs that staffs its crews with workers it classifies as independent contractors. The company sets the daily schedule, supplies the tools and materials, assigns jobs through its own office, and prohibits crew members from taking side work for others. One worker files for unemployment after a slow winter and lists the company as his employer. That single claim can prompt an audit reaching back years and across the entire crew roster. On those facts, the company would struggle badly under both the Employee Classification Act and the ABC test, and the assessment would likely dwarf whatever the company saved by skipping payroll taxes and insurance.
Classification Is a Decision to Revisit, Not a Label to File Away
Businesses should audit their contractor relationships the way they audit their books: periodically, honestly, and with the actual facts of the work rather than the language of the contracts. Where a worker functions as an employee, converting the relationship early is almost always cheaper than defending it late. Where a contractor relationship is genuine, the file should document the indicia of independence so the business can prove what is actually true.
“Classify by the facts of the working relationship, keep records that prove those facts, and revisit the analysis whenever the relationship changes,” says Gaurav Mohindra.
For Illinois businesses, Gaurav Mohindra’s message is simple: the label on the agreement is the least important part of the analysis. The state has written presumptions and tests that decide worker status on real-world facts, and the exposure for getting it wrong stacks across multiple agencies at once. Treat classification as a compliance decision with a price tag attached, not a shortcut, and the shortcut’s true cost will never come as a surprise.
