Co-employment is an arrangement in which two organizations share certain employer responsibilities for the same workers. It commonly occurs when a business partners with a Professional Employer Organization (PEO) to manage payroll, employee benefits, human resources, and employment-related administration while retaining control over daily business operations.
Under this arrangement, the client company directs employees’ work, manages performance, and makes operational decisions. The PEO handles the employment administration specified in the service agreement.
Co-employment allows businesses to outsource HR functions while maintaining direct working relationships with their employees. However, the arrangement does not automatically eliminate the client’s legal obligations as an employer.
How Does Co-Employment Work?
Co-employment works through an agreement that defines how a business and a PEO divide employer responsibilities.
The client company maintains its relationship with its employees and continues managing their work. The PEO provides administrative services and assumes specified responsibilities related to employment.
For example, a U.S. marketing agency with 20 employees might partner with a PEO to administer payroll, health insurance, benefits enrollment, and HR documentation.
The marketing agency continues assigning projects, supervising employees, setting performance expectations, and making business decisions. The PEO processes payroll, administers benefits, and provides the HR services established in the contract.
The arrangement operates through three connected relationships:
- Client company and employees: The business directs work, evaluates performance, and manages daily operations.
- PEO and employees: The PEO administers specified employment functions, including payroll, benefits, and HR support.
- Client company and PEO: Both organizations follow a service agreement that allocates administrative duties and other contractual responsibilities.
The exact division depends on the agreement, applicable employment laws, and the services the PEO provides.
Who Is Responsible for Employees in a Co-Employment Arrangement?
Both the client company and the PEO have responsibilities under a co-employment arrangement, although their obligations differ.
Client Company’s Responsibilities
The client company generally retains responsibility for managing its workforce and conducting business operations.
These responsibilities typically include hiring decisions, employee supervision, work assignments, performance evaluations, compensation decisions, workplace policies, and day-to-day working conditions.
The client also remains responsible for applicable employment laws governing the activities and conditions it controls.
A co-employment agreement does not automatically remove these obligations.
Professional Employer Organization’s Responsibilities
A Professional Employer Organization (PEO) provides employment administration and HR support through a contractual relationship with the client company.
Depending on the agreement, a PEO may handle payroll processing, employment tax administration, employee benefits, workers’ compensation insurance, HR documentation, and compliance assistance.
PEOs may also provide HR technology, employee onboarding support, and guidance on workplace policies.
The National Association of Professional Employer Organizations describes co-employment arrangements as contractual relationships that divide employer responsibilities between a PEO and its client.
Shared Responsibilities and Legal Liability
Some employment obligations may involve both organizations.
For example, a PEO might administer payroll while the client maintains responsibility for recording employees’ working hours accurately.
Similarly, a PEO might assist with workplace safety documentation while the client controls the actual working environment.
The allocation of responsibilities in a service agreement does not necessarily determine liability under every employment law. Courts and regulators may examine the actual working relationship, the organizations’ conduct, and the applicable legal standards.
Co-Employment vs. Joint Employment
Co-employment and joint employment describe related but distinct concepts. Co-employment commonly refers to a contractual arrangement that divides employer responsibilities, particularly between a business and a PEO. Joint employment refers to a legal determination that two or more organizations qualify as employers of the same worker under a particular law.
A company may enter a co-employment agreement without automatically establishing joint-employer status under every applicable statute.
For example, the U.S. Department of Labor explains that a PEO performing only administrative functions does not automatically become a joint employer under the Family and Medical Leave Act (FMLA).
When joint employment exists under the FMLA, the law assigns obligations to primary and secondary employers according to the circumstances of the employment relationship.
The Department of Labor’s guidance on joint employment under the FMLA explains how employers’ responsibilities can differ.
Businesses should evaluate co-employment and joint-employment questions under the specific laws that apply to their workforce.
Co-Employment vs. PEO, EOR, and Staffing Agencies
Co-employment, PEO services, Employer of Record services, and staffing arrangements describe different aspects of how companies hire, administer, and manage workers.
Co-Employment vs. PEO
A PEO is an organization that provides HR and employment administration services. Co-employment is the relationship commonly established between the PEO, its client, and the client’s employees.
The distinction is between the service provider and the employment arrangement.
A PEO commonly works with an existing workforce. It may administer payroll, benefits, and other employment functions while the client continues managing its employees.
Co-Employment vs. Employer of Record (EOR)
An Employer of Record (EOR) is a third-party organization that formally employs workers on behalf of another business.
EOR arrangements are frequently used when companies hire workers in countries where they do not have a local employing entity.
The EOR typically handles local employment contracts, payroll, statutory benefits, and employment administration. The client directs the employee’s work.
A traditional U.S. PEO co-employment arrangement generally involves an existing employer sharing specified employment responsibilities with a PEO.
An EOR arrangement instead focuses on establishing and administering an employment relationship through the EOR.
The precise legal obligations depend on local law, the contract, and the actual employment relationship.
Co-Employment vs. Staffing Agencies
A staffing agency recruits and supplies workers to businesses that need additional personnel.
Some staffing agencies also employ the workers they assign to clients, while others focus on recruitment and placement.
When a staffing agency employs a worker and the client supervises that worker’s daily activities, the arrangement may raise joint-employment questions under applicable law.
However, hiring through a staffing agency does not automatically establish a traditional PEO co-employment relationship.
The distinction depends on who employs the worker, which organization controls the work, and which employment responsibilities each party assumes.
Co-Employment vs. Direct Hire
Under a direct hire arrangement, a company recruits and employs a professional directly.
A recruitment agency may identify candidates, conduct assessments, and coordinate interviews, but the hiring company establishes and manages the employment relationship.
Direct hiring generally gives the company direct responsibility for employment administration unless it separately contracts with a provider for specific functions.
Benefits of Co-Employment for Businesses
Co-employment can reduce the administrative workload associated with managing employees.
Reduced HR Administration
A PEO can handle recurring HR activities such as payroll processing, benefits enrollment, and employment documentation.
This arrangement allows business managers to concentrate on employee supervision, customer relationships, and operational responsibilities while the PEO manages agreed administrative tasks.
Access to Employee Benefits
PEOs may give smaller businesses access to benefit plans and administrative resources that would be more difficult to obtain or manage independently.
Available benefits vary by provider, employer eligibility, plan terms, and applicable regulations.
HR and Compliance Support
PEOs can guide employment policies, payroll requirements, HR documentation, and employee relations.
Businesses can use this support to improve their internal processes and identify employment-related issues that require attention.
However, a PEO’s involvement does not guarantee compliance or eliminate the client’s responsibilities under employment law.
Centralized Employee Administration
A PEO may consolidate payroll records, benefit enrollment, employee information, and HR processes within one administrative system.
Centralization can make recurring employment administration easier to coordinate, particularly for businesses without a large internal HR department.
Risks and Legal Considerations of Co-Employment
Co-employment introduces contractual and operational dependencies that businesses should evaluate before entering an agreement.
Employment liability: A company may remain legally responsible for certain obligations even when a PEO administers related tasks. Employer status and liability depend on the applicable law and circumstances.
Payroll and tax obligations: Outsourcing payroll does not always transfer federal employment tax liability. The IRS explains that ordinary PEO arrangements may leave the common-law employer responsible for employment taxes. Special rules apply to qualifying arrangements with a Certified Professional Employer Organization (CPEO).
The IRS guidance on PEO employment tax responsibilities explains these distinctions.
Service agreements: Contracts should identify which organization handles payroll, benefits, tax administration, employee records, workplace safety, and employment-related disputes.
Employee communication: Workers should understand which organization manages their daily work and which organization administers payroll, benefits, and employment documentation.
Data protection: Both organizations may process employee information, making clear data access, confidentiality, and security requirements necessary.
Businesses should review these matters before establishing a co-employment relationship.
Does Co-Employment Apply to International Remote Employees?
Co-employment arrangements can involve international workers, but the legal structure depends on the country where the employee works.
The traditional U.S. PEO model does not automatically apply to workers in Latin America or other international markets.
Countries establish their own rules for employment relationships, payroll taxes, statutory benefits, labor protections, and employer responsibilities.
A U.S. company hiring a professional in Mexico, Colombia, Argentina, or another Latin American country must therefore evaluate the worker’s employment status and the obligations created under local law.
International staffing and EOR arrangements can provide different ways to organize these relationships.
For example, staffing services for companies hiring in Latin America can combine candidate recruitment, onboarding assistance, and ongoing administrative support.
Businesses may also use staff-to-hire arrangements when they want to begin through a staffing relationship and later transition a professional to a direct contractual relationship.
Alternatively, direct-hire recruitment allows companies to recruit professionals while taking responsibility for establishing and managing the resulting employment or contractual relationship.
Each model has different contractual and administrative characteristics. Businesses should determine the actual legal relationship rather than assuming that shared administrative responsibilities automatically constitute co-employment.
Frequently Asked Questions About Co-Employment
Who is the legal employer in a co-employment arrangement?
A co-employment arrangement involves two organizations with employment-related responsibilities for the same workers. In a typical PEO arrangement, the client remains the common-law employer and manages daily work, while the PEO assumes specified administrative responsibilities. Employer status for tax, benefits, or labor-law purposes depends on the applicable law and the arrangement’s facts.
Is co-employment legal?
Co-employment is a recognized business arrangement used by PEOs and their clients. Its legal treatment depends on applicable federal and state laws, the organizations’ responsibilities, and the terms of their agreement. Businesses must continue meeting any statutory obligations that apply to them.
Does co-employment mean employees have two bosses?
Co-employment generally gives employees one organization responsible for directing their daily work and another organization responsible for specified employment administration. The client company usually supervises performance and work assignments, while the PEO handles functions such as payroll, benefits, and HR support. The division should be clearly communicated to employees.
Does co-employment eliminate employer liability?
Co-employment does not eliminate employer liability. A PEO may assume certain contractual duties and statutory obligations, but the client can remain responsible for employment-law compliance, workplace conditions, or employment taxes. The specific obligations depend on the applicable law, provider status, and circumstances.
Can a staffing agency create a co-employment relationship?
A staffing arrangement can involve shared employment responsibilities and may result in joint-employer status under applicable law. However, staffing agencies and PEOs operate through different business models, and using a staffing agency does not automatically establish a PEO-style co-employment arrangement.
What is the difference between co-employment and outsourcing?
Co-employment establishes a relationship in which two organizations divide certain employer responsibilities for the same workers. Outsourcing is a broader practice in which a company contracts another organization to perform services or business functions. A company can outsource payroll, recruiting, or accounting without necessarily establishing a co-employment relationship.
Do companies need a PEO to hire remote employees?
Companies can hire remote employees through several arrangements, including direct employment, staffing, and Employer of Record services. A PEO is one option for businesses seeking shared employment administration, particularly for an existing workforce. The appropriate arrangement depends on employee location, local law, company structure, and administrative requirements.
Choosing the Right Employment Arrangement
Businesses should evaluate who will employ the worker, who will manage daily activities, who will administer payroll and benefits, and which organization will carry each legal obligation.
Co-employment may suit companies seeking HR administration through a PEO while maintaining control over their existing workforce.
Companies hiring remote professionals across borders may require a different arrangement based on local employment requirements and their preferred level of administrative involvement.
The remote hiring process can involve staffing, staff-to-hire, or direct-hire arrangements, depending on how the company wants to recruit, engage, and manage its professionals.
