Does a worksite employee work for the PEO or the client?

Both, in different ways. Day to day, the worksite employee works for and is directed by the client. For payroll, tax and benefits, the PEO is the employer of record. This shared arrangement is co-employment, and the split of duties is defined in the Client Service Agreement.

Why do a worksite employee's tax forms show the PEO?

Because a certified PEO files employment taxes under its own registration for the wages it pays. In the United States that means the worksite employee's federal tax forms reflect the PEO rather than the client. The client still directs the work and remains the day-to-day employer.

Can an Employer of Record have worksite employees?

Not accurately. The term applies to co-employment, where a PEO and client share employer status. An Employer of Record is the sole legal employer, so its workers are simply its employees. Calling them worksite employees imports co-employment language that does not describe the EOR relationship.

Does a worksite employee lose any employment rights?

No. A worksite employee keeps their statutory rights and benefits. Co-employment changes who administers payroll, tax and benefits, not the protections the worker is entitled to. The PEO and client together are responsible for meeting those obligations under the Client Service Agreement.

Worksite Employee

A worksite employee is a worker who is co-employed by a Professional Employer Organisation and a client company, working at or for the client's business whilst the PEO holds statutory employer status for payroll and compliance under the co-employment agreement.

What is Worksite Employee?

A worksite employee is a person employed under a co-employment arrangement, in which a Professional Employer Organisation (PEO) and a client company share employer responsibilities for the same worker. The employee performs work at or for the client's business, while the PEO acts as the employer for payroll, tax and compliance purposes.

The term belongs specifically to the PEO co-employment model. In the United States, a certified PEO is treated as the employer of its worksite employees for federal employment tax, which is why their tax forms reflect the PEO. The client still directs the work, sets pay and makes hiring and firing decisions.

Because the term is tied to co-employment, using it in an Employer of Record context is a mismatch. In an EOR arrangement, a single entity is the sole legal employer and the worker is simply its employee, not a co-employed worksite employee. Getting the terminology right avoids ambiguity in contracts and compliance.

Who is the employer of a worksite employee?

Both parties hold employer roles. The PEO is the employer for payroll, employment tax and benefits, acting under its own registration. The client is the employer for day-to-day direction, work assignment and performance. This split is the defining feature of co-employment and is set out in the Client Service Agreement.

Why is 'worksite employee' a PEO-specific term?

The term describes a worker whose employer status is shared between a PEO and a client, which only happens in co-employment. In US tax rules, a certified PEO is treated as the employer of its worksite employees for employment tax. That shared status is what the term names, so it does not fit models without co-employment.

Is a worksite employee the same as an EOR employee?

No. A worksite employee is co-employed, with employer status shared between a PEO and a client. An EOR employee has one legal employer, the Employer of Record, which holds full statutory responsibility in that country. Using worksite employee for an EOR worker can create contract ambiguity, so the terms should not be mixed.
