Yes. PEOs operate in all 50 states. Many states provide some form of specific licensing, registration, or regulation for PEOs. These states statutorily recognize PEOs as the employer or co-employer of worksite employees for many purposes, including workers' compensation and state unemployment insurance taxes. The IRS has accepted the right of a PEO to withhold and remit federal income and unemployment taxes for worksite employees. The IRS has promulgated specific guidance confirming the authority of PEOs to provide retirement benefits to workers.
