Federal Employee Retirement Contributions Act of 1999 - Amends Federal retirement provisions to reduce to seven percent after December 31, 1999, the required retirement contribution by Federal employees participating under the Civil Service Retirement System (CSRS) (such contribution currently is scheduled to be 7.4 percent for calendar year 2000, and 7.5 percent for 2001). Reduces similarly the required percentage contribution under CSRS for Members of Congress and congressional employees, law enforcement or firefighting personnel, certain judges and magistrates, and nuclear material couriers.
