Employment services classification clarifies distinct staffing service types and payroll responsibilities for taxation purposes. The classification organizes employment services for taxation into distinct service codes-executive search, permanent placement, contract staffing, temporary staffing, long term staffing (payrolling), temporary to permanent placement, co employment (PEO) arrangements, and other employment services-each defined by the provider client relationship, who bears payroll and legal responsibility, the hiring decision process, and the fee/payment basis, with specific exclusions and boundary notes such as the distinction between payrolling services and payroll processing.
