FERS MRA plus 10 Annuity

What is a FERS Minimum Retirement Age (MRA) plus 10 annuity?

This is a provision that allows you to retire with benefits beginning immediately if you have ten years of service and have reached the Minimum Retirement Age (at least 55). However, the annuity is reduced for each month you are under age 62. The reduction equals five percent per year (or 5/12 of one percent per month). To avoid the reduction, you can postpone payment. You can later apply for the benefit by writing to OPM or filing an "Application for Deferred or Postponed Retirement," Form RI 92-19. You should submit the form two months before you want the benefit to begin.
