Earning Credited Service
Credited service is the period of time you work for an SDRS participating employer, which is considered in your eligibility for benefits and the amount of benefits. Credited service represents complete or partial years of employment (you receive one-fourth of a year of credited service for each calendar quarter in which you make contributions to SDRS), as well as years of employment credited to you by retirement systems before consolidation into SDRS (before July 1, 1974).
Credited service includes time spent on authorized military leave of absence for your initial tour of duty, provided that you:
- Are employed before the leave,
- Return to public service within one year of discharge, and
- Remain employed for at least one year after returning.
Eligible members may purchase additional credited service in order to enhance their SDRS benefit at retirement. The cost to purchase credited service depends on your age at the time of purchase and is an actuarially-determined percentage of your salary.
The types of credited service that may be purchased include:
Prior public employment for which you are not eligible to receive a retirement benefit from for that period of service (subject to verification)
Nonqualified permissive service (air time) can be purchased if a member has at least five years of contributory service. A maximum of five years of air time may be purchased.
