Participation, Eligibility, Contributions, & Vesting


If you are a full-time employee of an SDRS participating employer, you are required to participate and make contributions to the South Dakota Retirement System. Full-time employees are those customarily working at least 20 hours per week and six months per year. Participation in the South Dakota Retirement System begins on the day of your first contribution.



Class A members include all state administrative employees, teachers, general employees of participating municipalities and counties, classified employees of participating school districts, and employees of the Board of Regents. All newly elected officials (except justices and judges) may participate.

You and your employer share the cost of your retirement benefits by contributing a percentage of your salary to the system. The amount of contributions is dependent on your class of service: 

  • Class A: 6% employee; 6% employer 
  • Class B Public Safety: 8% employee; 8% employer 
  • Class B Judicial: 9% employee; 9% employer 

Your contributions are deducted from your paycheck each pay period. SDRS contributions are made on a pre-tax basis, meaning that Federal income taxes are not withheld on contributions when they are made to the system. When you begin drawing benefits, your payments will become taxable. 



A member becomes vested and entitled to a retirement benefit after three years of contributory service, provided the member has not withdrawn their accumulated contributions.
