The End-Year Adjustment is to be filed on the web from Oct 25th, but if an employee is going to be posted between October and the end of December, does he/she need to file the End-Year Adjustment?

Those who will be posted between October and 12/24 (before the December payroll date) are subject to the End-Year Adjustment at the time of departure. Those who will be posted on or after 12/25 (December payroll date) will be subject to the End-Year Adjustment.
