Outsourcing Payroll and Third Party Payers
Employer’s Outsourcing Payroll Responsibilities
Many employers outsource some of their payroll and related tax duties to third-party payroll service providers. They can help assure filing deadlines and deposit requirements are met and greatly streamline business operations. But remember, employers are ultimately responsible for the payment of income tax withheld and both the employer and employee portions of social security and Medicare taxes.
Third Party Arrangements
Employers may designate or enter into an agreement with a third party in which the third party agrees to take over some or all of the employer’s Federal employment tax withholding, reporting and payment responsibilities and obligations. The following common third party arrangements are discussed in this section:
- Payroll Service Provider (PSP)
- Reporting Agent (RAF)
- Section 3504 Agent
Depending on the facts and circumstances, and the type of third-party arrangement, an employer who uses a third party to perform Federal employment tax functions on its behalf may remain solely liable for Federal employment taxes, or may become jointly and severally liable for such taxes.

The attached chart illustrates some differences in authority 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).
Reporting Agents (RAF)
Reporting Agents have long served an important role in our nation's tax collection system as a conduit between employers and the IRS. Reporting Agents improve the efficiency of IRS tax collection and compliance. Reporting Agents assist employers in making required tax deposits and tax information filings to the Federal Government and to state and local governments.
