PeopleSoft Base Benefits allows companies to manage employee benefits. It includes tools to create unlimited benefit plans that are grouped into benefit types like health or savings. Base Benefits integrates with other PeopleSoft applications and can administer COBRA and print HIPAA reports. Setting up base benefits involves four core phases - building supporting tables, creating benefit programs, assigning employees to programs, and calculating rates and deductions. Core tables must be set up first, then benefit plans are attached with details, plans are attached to programs, and finally employees are enrolled.
