The main difference between a PEO and an EOR is who legally employs the worker.

A PEO, or Professional Employer Organization, enters a co-employment relationship with your business. Your company usually remains the worker's common-law employer, while the PEO manages payroll, benefits, HR administration and certain employment tax responsibilities.

An EOR, or Employer of Record, becomes the legal employer of the worker. The EOR handles the employment contract, payroll, taxes, benefits and local compliance, while your company manages the worker's daily tasks and performance.

A 2012 U.S. Department of Labor advisory opinion describes the client as the direct employer in a typical PEO relationship. The choice usually comes down to two questions: Does your company already have a local entity, and which organization will sign the employment contract?

Choose a PEO when your company already has a legal entity and wants outsourced HR support. Choose an EOR when you want to hire employees in a country where your company does not have a legal entity.

What Is a PEO?

A PEO provides HR and employment administration through a co-employment arrangement.

A PEO may process payroll, withhold and remit taxes, administer benefits, manage workers' compensation and support HR compliance. Your company generally continues to run the business, supervise employees and make operational decisions.

The client company usually remains the direct or common-law employer. The PEO takes responsibility for specific employment administration and may become the employer for certain payroll or tax purposes. The division of responsibility depends on the service agreement, applicable state law and whether the PEO is IRS-certified.

What a PEO Usually Handles

  • Payroll processing
  • Payroll tax withholding and filings
  • Employee benefits administration
  • Workers' compensation support
  • Unemployment claims administration
  • HR policies and compliance guidance
  • Employee handbooks and onboarding support
  • Access to larger benefits programs

A PEO can give smaller companies access to benefits and HR systems that may be difficult to negotiate independently. The business usually retains more control over benefit selection and workforce decisions than it would under an EOR arrangement.

Does a PEO Become the Employer of Record?

Sometimes, but the phrase "employer of record" can create confusion in PEO discussions.

A PEO may be the employer for specific tax, payroll or benefits functions while the client remains the common-law employer. The U.S. Department of Labor describes the client as continuing to be the direct employer under common-law principles in a typical PEO relationship.

An IRS-certified PEO, known as a Certified Professional Employer Organization or CPEO, receives special treatment for certain federal employment tax obligations. The IRS generally treats a CPEO as the employer for covered worksite employees and remuneration paid by the CPEO, although exceptions and shared liabilities can apply.

What Is an EOR?

An EOR legally employs workers on behalf of a client company, usually in a country where the client does not have its own legal entity.

The EOR signs or administers the local employment contract, runs payroll, handles tax and statutory contributions, provides required benefits and manages local employment compliance.

Your company still manages the employee's daily work. Your managers can usually assign tasks, set objectives, review performance and direct operational activities. The EOR manages the legal and administrative side of employment.

What an EOR Usually Handles

  • Local employment contracts
  • Payroll and salary payments
  • Income tax and social contribution administration
  • Statutory benefits
  • Leave and holiday administration
  • Local employment registrations
  • HR documentation
  • Compliant onboarding and offboarding
  • Local termination procedures

An EOR allows a company to hire in a new country without immediately creating and maintaining its own subsidiary or branch. This makes the model useful for international expansion, remote hiring and testing demand in a new market.

The Biggest Difference: Entity Requirement

A PEO usually requires your company to have an entity in the country where the employee works. An EOR generally does not.

For example:

  • A U.S. software company with an established U.S. entity may use a PEO to outsource payroll, benefits and HR administration for its U.S. employees.
  • The same company may use an EOR to hire a software engineer in Germany before creating a German entity.
  • If the company later establishes its own German subsidiary, it may move the employee from the EOR to its own payroll or use a local payroll provider.

The entity requirement is often the quickest way to identify which model you need. Some providers use terms such as "global PEO" for services that function like an EOR. Review the contract to determine which legal entity will employ the worker.

PEO vs EOR: Liability and Control

A PEO and an EOR can both reduce administrative work, but they allocate employment responsibility differently.

With a PEO

Your company usually retains employer responsibilities connected to the business, workforce decisions and workplace conduct. The PEO handles the HR and payroll functions listed in the agreement, but your company may still have employment tax and employment law obligations.

The IRS states that businesses can remain responsible for employment taxes when they use a third-party payer, subject to rules such as the CPEO provisions.

With an EOR

The EOR assumes the formal legal employer role and handles local employment administration. This can reduce the need for your company to manage local registrations, payroll filings and employment contracts directly.

An EOR does not remove every employment-related risk. Your company still controls the employee's work and can create risk through discriminatory instructions, unsafe working conditions, inappropriate management or violations of the commercial agreement. The EOR should manage local employment formalities, while your company remains responsible for how it manages the person day to day.

Which Is Better for Your Business?

Choose a PEO If:

  • Your company already has a legal entity where the employee works.
  • You are hiring mainly in the United States.
  • You want to outsource payroll, benefits and HR administration.
  • You want access to broader group benefits.
  • You want to retain direct control over the employment structure.
  • You expect to maintain a stable domestic workforce.

Choose an EOR If:

  • Your company does not have a local entity in the employee's country.
  • You need to hire internationally without setting up a subsidiary.
  • You want to test a new market with a small team.
  • You need local employment contracts and payroll administration.
  • You want help complying with foreign employment rules.
  • You need to convert an international contractor into an employee.

PEO vs EOR Cost Considerations

A PEO usually charges a service fee based on payroll, headcount or the services included in the agreement. The IRS notes that PEOs commonly charge a percentage of payroll or another service fee.

An EOR commonly charges a per-employee fee, along with the employee's salary, statutory contributions, benefits and applicable local costs. The total cost can be higher than using your own entity, but the EOR avoids the immediate cost and administrative work involved in entity formation.

Compare more than the monthly service fee:

  1. Provider fees
  2. Payroll taxes and statutory contributions
  3. Benefits costs
  4. Currency conversion charges
  5. Onboarding and termination fees
  6. Legal or compliance surcharges
  7. Entity formation and maintenance costs
  8. The number of employees you expect to hire in each country

The Practical Decision

The provider's marketing label does not determine the employment model. The contract does.

Before signing, ask the provider:

  • Which legal entity signs the employment contract?
  • Who is responsible for payroll taxes?
  • Who is liable for employment-related penalties?
  • Who controls hiring, termination and performance decisions?
  • Which benefits are included?
  • What happens if local law conflicts with the service agreement?
  • Can employees later transfer to your own entity?

A PEO is generally the better fit for outsourced HR administration through an entity your company already owns. An EOR is generally the better fit for hiring in a country where your company does not yet have an entity. The legal employer named in the contract should confirm which arrangement you are buying.
