What Is an Employer of Record? How It Works for Illinois Businesses
An employer of record, commonly abbreviated as EOR, is a company that takes on the legal responsibilities of employing workers on behalf of another business. The employer of record handles payroll processing, tax withholding and filing, workers compensation insurance, unemployment insurance, and compliance with employment laws, while the actual day-to-day work direction and supervision remains with the client business.
For Illinois businesses that need workers without the administrative burden of direct employment, or for companies that want to bring on temporary or project-based staff without becoming the employer of record themselves, this model provides a clean, compliant solution.
This guide explains exactly how the employer of record model works in Illinois, who should use it, how it differs from related models like PEO and staffing agencies, and what Illinois-specific compliance requirements make it particularly relevant in this market.
How the Employer of Record Model Works
The structure is straightforward once you understand the three parties involved.
The worker performs the actual job. They show up, do the work, and receive direction from the client business on a daily basis. From a practical standpoint, their day-to-day experience is similar to being a direct employee of the business they work at.
The employer of record is the legal employer. The EOR puts the worker on its own payroll, withholds the correct federal, state, and local taxes, pays the employer share of payroll taxes, maintains workers compensation coverage, and handles all the administrative and compliance functions associated with employing that worker. The worker is technically an employee of the EOR, not of the client business.
The client business directs the work. They decide what the worker does, when they work, and how they perform the role. They pay the EOR a rate that covers the worker’s compensation plus the EOR’s costs and fees. They receive the labor without taking on the employment responsibilities.
This separation between who supervises the work and who handles the employment administration is the defining feature of the employer of record model.
What an Employer of Record Handles in Illinois
Illinois has a specific set of employment laws and local ordinances that add compliance layers beyond federal requirements. An employer of record operating in Illinois handles all of the following on behalf of client businesses.
Federal payroll tax compliance. Social Security and Medicare tax withholding and employer matching, federal income tax withholding, and federal unemployment tax, FUTA, contributions are all handled by the EOR.
Illinois state income tax withholding. Illinois has a flat state income tax rate. The EOR handles withholding and remittance to the Illinois Department of Revenue on behalf of every worker on its payroll.
Illinois unemployment insurance. Employers in Illinois contribute to the state unemployment insurance fund through the Illinois Department of Employment Security, or IDES. The EOR manages these contributions for the workers on its payroll.
Cook County and Chicago-specific ordinances. For workers performing work in Chicago or Cook County, the EOR must comply with local ordinances including the Chicago Minimum Wage Ordinance, the Cook County Earned Sick Leave Ordinance, and the Chicago Paid Leave and Paid Sick and Safe Leave Ordinance. These local requirements create additional compliance obligations beyond what state law requires, and they are a frequent source of exposure for businesses that do not realize the local requirements apply.
Workers compensation insurance. Illinois law requires employers to carry workers compensation insurance covering all employees. The EOR maintains this coverage for every worker on its payroll, protecting the client business from workers compensation liability for those workers.
New hire reporting. Illinois requires employers to report new hires to the Illinois New Hire Reporting Center within 20 days of hiring. The EOR handles this reporting for all workers it places.
I-9 employment eligibility verification. The EOR handles I-9 verification for every worker it employs, maintaining the required documentation.
For businesses operating in Chicago, the combination of federal, Illinois state, and Chicago and Cook County local requirements creates a significant compliance burden that many small and mid-sized businesses are not fully equipped to manage on their own. The employer of record model transfers that burden to a specialist.

Employer of Record vs PEO: What Is the Difference?
These two models are frequently confused because they both involve a third party handling employment administration. The distinction is important.
A PEO, or Professional Employer Organization, enters into a co-employment relationship with the client business. The client business and the PEO are both considered employers of the workers. The PEO typically handles HR administration, benefits, payroll, and compliance, but the client business is still an employer of record for the workers. PEOs generally require the client business to have some minimum level of existing employees and to maintain a longer-term service relationship.
An employer of record is the sole legal employer of the workers. The client business has no employer of record status for those workers. This is a cleaner separation that works well for temporary workers, project-based staffing, workers in a new location where the client does not yet have an established entity, and situations where the client wants to completely remove employment administration from their plate.
For businesses in Greater Chicago using temporary or contingent workers through a staffing agency, the staffing agency typically functions as the employer of record during the placement period. This is one of the core services that a staffing relationship provides, and it is often underappreciated by businesses that think of staffing agencies only as recruiting services.
Employer of Record vs Staffing Agency: How They Overlap
A staffing agency that places workers at client businesses is functioning as an employer of record for those workers during the placement period. This is not a coincidence. The employer of record function is built into how staffing placements work by design.
When Apex WorkForce Partners places a warehouse associate, forklift operator, or administrative assistant at a client facility, that worker is on Apex WFP’s payroll. We withhold and remit their taxes, carry their workers compensation coverage, manage their Illinois unemployment insurance contributions, and ensure compliance with all applicable Chicago, Cook County, and Illinois employment requirements. The client business directs the work. We handle the employment.
The difference between a pure employer of record service and a full staffing agency relationship is primarily in the recruiting and placement function. A pure EOR service takes workers that the client has already found and simply handles the employment administration. A staffing agency like Apex WFP both recruits and screens candidates and functions as their employer of record.
For businesses that have already identified the workers they want, but need a compliant employer of record to put them on payroll, our Payroll Services offering provides exactly this function.
When Should an Illinois Business Use an Employer of Record?
The employer of record model makes sense in several specific situations that Illinois businesses commonly encounter.
When using temporary or contingent workers. Rather than putting temporary workers on your own payroll with all the associated tax and compliance obligations, an EOR handles all of that while you direct the work. This is the standard model for businesses that use staffing agencies.
When hiring workers in Chicago or Cook County without full local compliance infrastructure. The Chicago and Cook County ordinance requirements are specific and frequently updated. Businesses without dedicated HR and payroll staff familiar with these requirements face real compliance risk. An EOR that specializes in Illinois and Chicago compliance handles these requirements correctly.
When expanding into Illinois from out of state. A business headquartered outside Illinois that wants to place workers in the state without establishing a legal entity in Illinois first can use an EOR to employ those workers compliantly while the entity setup proceeds.
When the cost of maintaining an in-house payroll function exceeds the EOR service cost. For smaller businesses, the loaded cost of managing payroll in-house, including payroll software, HR time, and compliance risk, often exceeds what an EOR charges for the same function.
When workers compensation risk management is a priority. Industries with higher workers compensation risk, including warehousing, manufacturing, and logistics, benefit from an EOR that maintains workers compensation coverage and manages claims, rather than the client business absorbing that risk directly.
Illinois-Specific Compliance Requirements That Make EOR Valuable
Illinois has employment laws that go beyond federal requirements and create specific compliance obligations for Chicago-area employers.
The Illinois Wage Payment and Collection Act governs how and when wages must be paid to Illinois employees. It includes specific rules about final pay timing, deductions from wages, and employee rights related to pay disputes.
The Illinois Human Rights Act adds protected classes beyond federal employment discrimination law, including prohibitions on discrimination based on ancestry, marital status, military status, and unfavorable discharge from military service.
The Illinois Day and Temporary Labor Services Act specifically governs the relationship between staffing agencies, their client businesses, and the workers they place. It includes requirements related to day rate pay structures, equal pay for equal work provisions, and conditions for converting temporary workers to permanent status.
The Chicago Paid Leave and Paid Sick and Safe Leave Ordinance, effective in 2024, requires covered employers to provide both paid sick leave and paid leave to covered employees working in Chicago. The specific accrual rates, usage rights, and employer obligations under this ordinance are distinct from state law requirements.
An employer of record that operates in Illinois and specifically in Chicago and Cook County is responsible for maintaining current compliance with all of these requirements. For client businesses, this means the compliance burden shifts to a specialist rather than landing on internal HR or finance staff who may not have the bandwidth to stay current on local ordinance changes.
