Early History
Employee leasing in the United States began as early as the 1940's. In the early 1970's, the concept was popularized by a consultant named Martin Selter, who leased the employees of a doctor's office in Southern California. The Employee Retirement Income Security Act of 1974 (ERISA) contained an exemption for multiple employer welfare arrangements (MEWA), which provided a loophole for employers with leased employees to claim they were exempt from the ERISA requirements. Passage of the Tax Equity and Fiscal Responsibility Act of 1982 (TEFRA) further encouraged employee leasing by providing a tax shelter for employers who contributed a minimum amount to employee plans. More stringent guidelines in the Tax Reform Act of 1986 later eliminated most of the TEFRA incentive, however.By 2007, there were approximately 400 PEOs operating in the United States.
