Final answer:
Payroll's responsibility in respect to Quebec Parental Insurance Plan (QPIP) primarily involves the calculation and remittance of QPIP contributions, as part of the broader payroll tax responsibilities.
Step-by-step explanation:
The Quebec Parental Insurance Plan (QPIP) responsibilities in payroll mainly relate to the calculation and remittance of QPIP contributions. This falls under the broader purview of payroll taxes, which are a mandatory aspect of an employer's payroll process.
Payroll taxes include not just QPIP but also other components such as employee insurance, retirement plans, employer payments to Social Security, unemployment and worker's compensation insurance, and other benefits like Medicare. In comparison, managing workplace safety protocols falls under a different area of responsibility within an organization and is not directly related to payroll's tasks.
