Payrolls

Calculate gross up for a payroll

Calculates gross up earnings for an employee's payroll, given net earnings. This endpoint is only applicable to off-cycle unprocessed payrolls.

The gross up amount must then be mapped to the corresponding fixed compensation earning type to get the correct payroll amount. For example, for bonus off-cycles, the gross up amount should be set with the Bonus earning type in the payroll fixed_compensations field.
