Combined Service Annuity (CSA)

Under the Combined Service Annuity (CSA) law, various Minnesota public retirement plans work together so you receive credit for all of your service. If you are covered by another Minnesota public retirement plan, this service may coordinate with your service as a state employee.

Minnesota retirement plans covered under CSA law

  • Minnesota State Retirement System (MSRS)

  • Public Employees Retirement Association (PERA)

  • Teachers Retirement Association (TRA)

  • St. Paul Teachers Retirement Fund Association (SPTRFA)

  • Duluth Teachers Retirement Fund Association (DTRFA)


When you switch Minnesota public employers
Your pension contributions and service credit are not rolled into the new plan. The service credit earned will remain with the fund where the service was earned. When you retire, you will receive payment from each public retirement association.

Be sure to notify MSRS if you have service with another pension plan so we can contact the other fund to provide accurate benefit information.


CSA eligibility requirements

  • Hired before July 1, 2010:  you must have three years of service in two or more Minnesota public retirement plans (Judges and Legislators Plans require more), with a minimum of six months of service in each plan. You must start receiving retirement benefits from all of the plans within one year of each other.

  • Hired July 1, 2010 or after:  you must have five years of service in two or more Minnesota public retirement plans (Judges and Legislators Plans require more) with a minimum of six months of service with each plan. You must start receiving retirement benefits from all of the plans within one year of each other.


Example of how CSA works

Paul has seven years of Minnesota public employment. He worked two years for a Minnesota county. His position was covered by PERA and five years for the State of Minnesota. His position was covered under the MSRS General Employees Retirement Plan. 

  • To calculate his retirement benefit, both MSRS and PERA will use the same five-high salary. We review salary from his entire 7-year public employment to determine the 60 month period with the highest average salary. 

  • In retirement, he will receive two monthly benefit payments: one from PERA representing his two years of service and one from MSRS for his five years of service.
