Retirement code 'K'


Q: I am a federal firefighter working in a “secondary firefighter” position. My LES shows a FERS retirement code of “K.” What benefits/retirement does this code entail? I also heard that legislation is in the works to increase the mandatory primary  firefighter retirement age from 57 to either 62 or 65? Is there any truth to that?

A: “K” applies to anyone covered by FERS and FICA who will be entitled to regular retirement benefits. Any period of service which is classified as “K” isn’t covered service for law enforcement or firefighter retirement purposes. I don’t pay attention to legislation that is in the works because most bills don’t become law, and those that do seldom have provisions in them that look the way they started out. There are enough real problems to worry about without fretting over those that might be.

    I was first hired as a GS civilian under the FERS program in August 2011 – February 2015. My FERS deduction code was ‘K’. I resigned, had a year gap of service and re-enter the GS under FERS. From Feb 2016 until Jan 2017, my FERS code was listed as “KF” and a higher rate of money was withheld for Retire, FERS (KF). From Jan 2017 until present, my FERS retire code was changed to “F” and my FERS Retire contribution rate lowered to what it had been from Aug 2011 – Feb 2015. However, I received no reimbursement/refund for the hire FERS withholding rate from Feb 2016 – Jan 2017. Is this all correct? Thanks

    • Because you were first hired before 2013, your contribution rate was set at .08 percent (K). You left when you had fewer than 5 years of service. When you returned, your contribution rate was erroneously set at 4.4 percent (KF). When the error was found, it should have been changed to 3.1 percent (KR). Any excess reduction must be returned to you by your agency.

  2. Hi, I was in the military for 16.5 years (1992 -2008) and then join USPTO federal civilian service from 2014 – 2018. I am 30% disable veteran(I’m not sure if it matters), but I see a retirement code of FERS (Code KF) with a Retirement SCD of 9/08/2014. What does this retirement date and Code FERS KF mean in my situation?

  3. Greetings – Before joining FDA as a civilian employee in 2013, I was employed as a civilian employee with the USDA for 15 years (1998-2013). It is now 2019, and I have just realized now that my FERS category was moved into the “KR” category. FERS-RAE was established in 2013 and I guess i was accidentally put in this category as a new hire. I have been contributing more than I should be due to being placed in the FERS-RAE category. What are my options here?

    • If you were placed in the wrong retirement category, you need to go to your personnel office, point out the error, and ask to have them work with OPM to have it corrected. If you are right, you would be due a refund for having over-contributed to the retirement fund.

  4. Hello,

    I started working for the federal government in 2016, I had two transfers with no break I service since then. Recently, I was informed that my first job erroneously coded me as KF, the second job continued to use KF. With my current job, they notice the error and informed me I should’ve been placed/moved to KR.

    What does this mean in my situation?

    • I don’t know hat it means in you case. However, I can provide you with the official definitions of those two categories:

      KF: Federal Employees Retirement System (FERS) Further Revised Annuity Employees (FRAE) and FICA. Combination of FICA and FERS-FRAE. Full deductions are withheld for FICA, and partial deductions are withheld for another system. FERS (FRAE) FICA.

      KR: Federal Employees Retirement System (FERS) Revised Annuity Employees (RAE) and FICA. Combinations of FICA and Partial Deductions: Full deductions are withheld for FICA, and partial deductions are withheld for another system. When the employee’s basic pay exceeds the maximum FICA wage base and is no longer subject to FICA withholding, full deductions are withheld for CSRS, CSRS-Special, FSRDS, or Other Retirement Systems.

    Hello, I started my Federal career under a 12(d) primary covered position in 2011. I recently left that position due to family issues, and transferred directly to a regular non-LEO/non-FF job in another agency, but my SF-50 still has code M for LEO/FF retirement, and my last pay statement has a FERS deduction for the appropriate higher rate to match a covered position.

    My question is…..if they never catch it, will I still eventually be entitled to a full covered retirement? Does someone audit all your SF-50s and payroll when you file to retire? If they catch it, can they retroactively undo the time that I was listed as code M coverage for the non-LEO/non-FF job I currently hold?

    • They will catch it eventually, so your best move is to let your personnel office know about the error now.
