Service Computation Date (SCD)
The service Computation Date (SCD) determines an employee’s eligibility
for a specific benefit or entitlement. There are four types of SCDs: Leave,
Retirement, Thrift Savings Plan, and Reduction-In-Force (RIF).
- The Leave SCD determines whether the employee will earn four, six, or
eight hours of annual leave each pay period, and is reflected in block #31
of the Standard Form (SF) 50.
- The Retirement SCD is used to determine the total amount of Federal
service that is used to determine retirement eligibility. An employee’s
retirement SCD is often the date of his/her first Federal appointment that
was covered under the CSRS, CSRS-Offset, or FERS. The retirement SCD may be
adjusted forward (less total time) to account for time that is not
creditable for retirement or adjusted backwards (more total time) to account
for such things as military service and service credit payments for
previously non-creditable time.
- Time not creditable for retirement (and may affect the Retirement SCD):
- Excess leave without pay (LWOP);
- Federal service requiring a deposit that has not been paid;
- Temporary service performed after 1989 (FERS only); and
- Breaks in Federal service in excess of three days.
- The TSP service computation date is used for vesting purposes and is
required only for an employee covered by the FERS retirement system. All
Federal Civilian service time is included in this SCD, but the date may not
reflect a value earlier than 1 January 1984.
- The RIF SCD is one of four factors used to determine an employee’s
retention standing and final placement on a retention register for RIF
purposes. The RIF SCD includes all creditable military and civilian service
and is adjusted with additional credit (up to a maximum of 20 years) for the
employee’s performance ratings. The “adjusted” RIF-SCD is reflected on the
retention register and is included in the RIF notice provided to an impacted
