Third Party Arrangement Chart
There are some differences between a payroll service provider, reporting agent authorized under Form 8655, Reporting Agent Authorization (PDF) and an agent appointed using Form 2678, Employer/Payer Appointment of Agent (PDF).
A Form 8655 (PDF) reporting agent provides payroll services for one or more employers, using each client’s (employer’s) employer identification number (EIN) to file separate returns (generally e-file only) on the client’s behalf. A reporting agent may also deposit and pay taxes on the client's behalf.
A Form 2678 (PDF) agent acts as the employer, assuming liability along with the employer for the employer’s Social Security, Medicare and federal income tax withholding responsibilities. An agent appointed under Form 2678 files aggregate returns (e-file or paper) using the agent’s EIN.
The chart below illustrates the most significant differences.
