What is the difference between an employer of record and a staffing agency?

A staffing agency recruits workers, while an employer of record arrangement provides employment for workers performing services for a client. For temporary staffing, the agency also employs and pays the worker, so the functions can overlap. Start by asking whether you need a candidate search or employment support for someone already identified. Then confirm the payroll, supervision and tax responsibilities in the proposed arrangement.

What is the difference between a PEO and a staffing agency?

A PEO can support your existing workforce with HR, payroll and benefits administration, while a staffing agency helps recruit people for open roles. In temporary staffing, the agency keeps the assigned worker on its payroll. Direct hire puts the selected person on your payroll. A PEO's services may include recruiting, so compare the actual scope instead of assuming the labels make the services mutually exclusive.

Is a PEO the same as an employer of record?

A PEO and an employer of record are not interchangeable service descriptions, although their functions can overlap. PEO arrangements are also known as co-employment, with the provider handling agreed employment functions for a client's workforce. EOR describes a provider employing workers who serve the client. Neither label alone tells you the federal tax result. For that, identify the arrangement and verify whether the provider is an IRS-certified PEO.

What is a certified professional employer organization?

A certified professional employer organization is a PEO that has applied for and received IRS certification after meeting the applicable requirements. Certification is voluntary and has specific federal employment tax consequences. According to the IRS chart, the CPEO is generally solely liable for taxes on wages it pays to worksite employees. That rule is limited: it does not mean every worker or every employment obligation receives the same treatment.

Who pays employment taxes when you use a PEO?

A PEO may handle employment tax payments, but who remains liable depends on the actual arrangement and certification status. The IRS generally places sole liability on a CPEO for wages it pays to worksite employees; the customer may share liability for non-worksite employees. With a noncertified PEO, client liability may remain. Ask your tax adviser to distinguish responsibility for making a payment from liability if that payment is missed.

Can a staffing agency also act as the employer of record?

For temporary workers it places, a staffing agency can be the employer on payroll while the client directs the work. Our temporary employees stay on our payroll while working for you. That describes the temporary staffing arrangement; it does not establish that we offer every service marketed as an EOR. For a proposed assignment, confirm the employment responsibilities and location-specific requirements instead of relying on the label alone.

Employer of Record vs Staffing Agency

A staffing agency finds workers and, for temporary assignments, employs them while you direct their work. A PEO helps administer your existing workforce through co-employment. An employer of record employs a worker for your business under an arrangement that leaves you directing the work.

According to the IRS, a certified professional employer organization is generally solely liable for the federal employment taxes on the wages it pays to worksite employees, while an employer that uses an ordinary payroll service provider remains liable for its own tax filings, deposits and payments.

At FIS Recruitment, we find and screen candidates, and our temporary employees stay on our payroll while working for you.

The short answer

Start with the problem you need solved: finding people, administering the people you already employ, or arranging employment for someone you want to hire. Staffing agencies, PEOs and employers of record address those different needs, but their service labels alone do not determine who carries federal employment tax liability.

Staffing agency: recruits workers and employs temporary staff assigned to clients; direct hires join the client's payroll.
PEO: shares employment responsibilities through a co-employment arrangement, with services that can include HR, payroll and benefits.
Employer of record: an industry label for a provider that employs workers performing services for a client.

Employer of record is not a separate category in the IRS third-party arrangement chart. Read the agreement and verify the provider's actual tax status instead of treating the label as a legal answer.

Side by side

The practical difference is where each service enters your hiring process. Temporary staffing starts with a vacancy, a PEO can support an existing workforce, and an EOR arrangement can support an identified hire. Use this comparison to organize provider discussions, then confirm the responsibilities for your particular workers and location.

What a PEO does (and what "certified" changes)

A PEO can take on payroll, benefits and HR administration while you continue managing the work. Co-employment describes that sharing of responsibilities. IRS certification adds a specific federal employment tax framework, so comparing a PEO with a staffing agency requires more than checking whether both can process payroll.

The IRS CPEO program is voluntary. A certified professional employer organization has applied and met the IRS requirements. Ask for the provider's exact legal name and verify its current certification through the IRS public listings.

The worksite-employee limit matters. Under the IRS chart, a CPEO and its customer may both be liable for taxes on wages the CPEO pays to non-worksite employees. Ask which category covers your workers.

For a noncertified PEO, the IRS Internal Revenue Manual explains that client liability may remain and, in some arrangements, the provider and client are concurrently liable. Federal tax law determines that liability; a private contract cannot rewrite it.

What an employer of record does

An employer of record arrangement puts the worker's employment with a provider while your business directs the work. It is worth investigating when you have identified someone to hire but lack local employment infrastructure. Confirm the provider's legal presence and the specific employment responsibilities it accepts in that location.

For a hire in another state or country, ask whether the proposed arrangement is available there and which obligations remain with your business. Do not assume the EOR label removes every registration, tax or employment requirement.

If you want to move a contractor into employment, ask whether the provider supports that transition and what review is required. Treat it as a question to resolve before signing, not an automatic result of buying an EOR service.

What a staffing agency does

A staffing agency helps fill a vacancy by recruiting candidates, and temporary staffing adds an employment and payroll arrangement for the assignment. The client directs the work at its site. Direct hire works differently: the agency recruits, but the selected person joins the client's payroll rather than remaining an agency employee.

Temp: an agency employee works on an assignment for your business.
Temp-to-hire: the assignment provides a chance to evaluate the worker before a possible move to your payroll.
Direct hire: the agency recruits someone for employment directly with your company.

Compare temp vs temp-to-hire vs direct hire, or review how temp to hire works before deciding on conversion terms.

At FIS Recruitment, we phone screen and interview candidates and conduct reference checks before presenting them. Our temporary employees remain on our payroll while working for you. See how we work with employers to match the staffing model to your open role.

Which one do you need?

Choose the service around the gap in your operation before comparing provider proposals. An unfilled shift, an overloaded payroll function and an identified international hire are different starting points. Write down the outcome you need, then ask each provider to explain the responsibilities it would take on to deliver it.

You need people you do not have: start with a staffing agency.
You have staff and need HR, payroll or benefits support: evaluate a PEO.
You have a worker in mind but need an employment arrangement for the location: investigate an EOR.

You can explore combining services, such as recruiting help alongside payroll administration. Make the handoff explicit: identify who employs each worker, who receives approved hours and who answers payroll questions.

Questions to ask any provider

Ask each provider to describe the employment relationship, tax responsibilities and exit process in writing. Compare the answers against the proposed agreement rather than relying on a sales label. A useful proposal should make it clear who does the work, who remains responsible and how you will resolve a problem.

Who is the legal employer, and for which purposes?
Who files returns, makes deposits and pays employment taxes?
If this is a PEO, is the contracting entity currently IRS-certified?
Who carries workers' compensation coverage for this assignment and location?
How does the arrangement end, and who handles the transition?
What does the service cost, what is included and what requires separate approval?

For staffing proposals, review what a staffing bill rate covers before comparing the scope of service.

Frequently asked questions

The main distinction is between recruiting a worker and administering or providing that worker's employment. Payroll can appear in every model, which is why it is easy to confuse them.
