ADP week numbers are determined based on which of the following?

The determination of ADP week numbers being based on the input date is correct because the input date reflects when the payroll data is actually entered into the system. This is crucial for the processing schedule, as it allows ADP to accurately calculate and manage payroll cycles based on the data provided by employers. The input date serves as a trigger for starting the payroll process, aligning with the weeks in which work hours are calculated and payment is disbursed. Ensuring that week numbers align with the input date helps maintain consistency in payroll reporting and compliance.

Other options, such as employee start date, payroll submission date, and federal tax deadlines, do not directly determine week numbers in this context. Employee start dates relate to individual employee records and may affect personal payroll but not the overall week numbering for processing cycles. Payroll submission dates are important for tracking when payroll is finalized but do not influence how weeks are numbered. Similarly, federal tax deadlines are critical for compliance but do not dictate the weekly payroll structure within the ADP system. Thus, focusing on input date aligns with operational processes specific to managing payroll effectively.
