During the 2003 open seasons for the Thrift Savings Plan, which are scheduled to run from April 15 to June 30, and Oct. 15 to Dec. 31 in 2003, service members can increase their basic pay contribution from 7 percent to 8 percent (if they have not already done so), and can continue to contribute up to 100 percent of their special, incentive or bonus pays. For those serving in a combat zone, the ceiling for contributions is $40,000. Also, for 2003 the IRS elective deferral limit has increased from $11,000 to $12,000. The deferral limit for 2004 will be $13,000; for 2005, $14,000; and $15,000 for 2006. TSP enrollment can be done online at https://emss.dfas.mil/mypay.asp, or by turning in a TSP enrollment form (TSP-U-1) to the servicing pay or personnel office.
