Meanwhile, time also is running short for FERS employees to make any adjustments needed in ongoing investments if they are on an investing schedule to hit the regular investment limit of $17,500 before the end of the year. To get the maximum government contributions, FERS participants need to structure their investments so that they are putting in at least 5 percent of salary each pay period of the year; in some cases, they may need to cut back on their biweekly investment amounts. If there is any question, they should check with their payroll offices how many TSP investment dates (which are not necessarily the same as pay dates) are left for them in the year, and adjust accordingly. That is not an issue for CSRS investors, who get no government contributions.
