Blended Retirement System

Air Force Reserve: Active Duty

Benefit Fact Sheet


The Blended Retirement System (BRS) went into effect on 1 January 2018.  The BRS applies to all Service members who entered the Uniformed Services with a Date of Initial Entry into Military Service (DIEMS) of 1 January 2018 or later.  The BRS is a combination of a defined benefit plan, similar to predecessor plans that pay monthly retired pay, plus defined contributions and service matching to the Federal Thrift Savings Plan (TSP). 

Implementation of 5% Automatic Enrollment Percentage for Thrift Savings Plan Participants

On October 1, 2020, the Federal Retirement Thrift Investment Board (FRTIB) will increase the automatic enrollment percentage from 3% to 5% of pay for all  and Blended Retirement System (BRS) participants who are automatically enrolled in the TSP on or after October 1, 2020, and for BRS participants automatically re-enrolled in the TSP on or after January 1, 2021, per 5 CFR § 1600.34 and 1600.37. This change will not affect the contribution rates in place for BRS participants who were automatically enrolled prior to October 1, 2020, and did not terminate their contributions.  Click here for more information.
