Can I Earn A Military Pension And A Civil-Service Pension

A reader asks:

I served 14 years of active duty and six years in the National Guard. I received my 20-year letter.

I began working for the postal service and “bought back” my 14 years of active duty towards my postal service retirement. For example I have 12 years actual with the postal service but 26 years on the books due to the buy back option.

My question is, how does this affect my retirement through the National Guard when I reach age 60? Will I receive retirement pay for only my six years served in National Guard, or for the full 20 years of military service?

I guess what I am asking if it was “beneficial” for me to buy back my military time. Do I lose the six years of National Guard time if I buy back my 14 years of active duty time? I suppose I am a little confused as to what happens to the six years for National Guard time since the time spent in the Guard after the buy back would be less than 20 years.


This is a great question on a very confusing issue. (If there’s anything more complicated than retiring from the military, it’s retiring from federal civil service.) Federal law entitles military veterans who become federal civil service employees to receive credit for their military service by “buying back” their active duty time. The money they pay to the Federal Employees Retirement System pension fund for each year of their active-duty time gives them an additional year of credit toward their FERS pension.

For veterans entering federal civil service after active duty, the military service credit deposit is a fantastic way to boost the civil service pension. When our reader left active duty after 14 years, they were not eligible for a military pension. The only way to receive some sort of retirement benefit for those years of active duty is to transfer to the Reserves or National Guard… or start a bridge career with the federal civil service.

In this case, the reader paid a meaningful sum of money (out of their own savings) to be credited with an additional 14 years of time for their civil-service pension. In most cases, that investment is a great move! They’re eligible for a larger pension (because they paid for it) and they receive additional credit toward two more civil-service seniority benefits.

[Note: this reader made a smart choice. If you’re a military veteran in the federal civil service, it’s almost always a good idea to buy your military service credit deposit. Read the comprehensive guide to the military service credit deposit, and scrape up the money to boost your retirement. You can’t get this return from the stock market or in real estate. If you’re already retired from active duty and you’re in the federal civil service, you can still get a couple of free deals on your federal Service Computation Date.]

Now the reader has a good deal on federal civil-service retirement. But what happens when they continue to drill with the National Guard and then qualify for that pension as well?

The issue behind the reader’s National Guard retirement question is the type of military service:

  1. less than 20 years of active duty without qualifying for an active-duty pension, or
  2. 20 years (or more) of active duty resulting in an active-duty pension, or
  3. a combination of active duty and more years in the Reserve or National Guard, resulting in a Reserve/Guard pension at age 60.

1. In the first case, the veteran could buy back that time toward a federal civil service pension with the military service credit deposit.

2. In the second case, federal laws against “double dipping” would require the military retiree to waive their military retirement pay if they buy the civil service’s military service credit deposit. This is a bad financial move.  Military retirees could still request two other civil-service benefits which are based on their active-duty service, and those benefits are worth applying for.

3. Federal law makes an exception! The federal civil service employee can still make a military service credit deposit for their years of active duty, and they can also receive a Reserve/Guard pension. They’ve earned that Reserve/Guard pension on their own and they haven’t bought it as a credit, even though they took the credit for their active-duty service.

I realize that this looks too good to be true. (A great deal from both the military and the federal civil service?!?) A Reserve/Guard retirement is handled under Chapter 1223 of federal law (10 U.S.C. 12731). The details of the civil-service exception are in Chapter 22 of the CSRS/FERS Handbook. Here’s the quote from Chapter 22 section 22A4.1-1 of the CSRS/FERS Handbook. The specific rule from the “Receipt of Military Retired Pay” section is in the third bullet point:

In determining eligibility for CSRS retirement or in estimating the amount of annuity for an employee (special rules for survivors of employees who die in service are covered in Chapter 70), who receives military retired or retainer pay, do not give credit for any military service at the date of separation for civilian retirement unless one of the following is true.

2. The employee is receiving military retired pay that was awarded:
On account of a service-connected disability incurred in combat with an enemy of the United States; or

On account of a service-connected disability caused by an instrumentality of war and incurred in the line of duty during a period of war; or
Under the provisions of 10 U.S.C. 12731-12739 (Chapter 1223) which grants retired pay to members of reserve components of the armed forces on the basis of age and service (active and reserve).

For those who’ve noted that the section refers to the old CSRS pension system, not the current FERS pension, it’s covered under section 22B1.1-1.C “Applicable CSRS Provisions”:

The following sections and parts of subchapter 22A apply to FERS employees:
Part 22A4: Receipt of Military Retired Pay .

Bottom line: if you serve in the Reserve or National Guard and also work in the federal civil service, then you can take your military service credit deposit and still receive your full Reserve/Guard pension. You’ve earned both of them!

WHAT I DO: I help you reach financial independence. For free. I retired in 2002 after 20 years in the Navy's submarine force. I wrote "The Military Guide to Financial Independence and Retirement" to share the stories of over 50 other financially independent servicemembers, veterans, and families. All of my writing revenue is donated to military-friendly charities.

  1. Follow up question: Will buying back active duty time performed while in the reserves (ie. Mobilization, ADSW) affect/reduce your military reserve pension? I’m FERS and have bought back my original initial active duty time of 5 years and am now retired from the reserves with considerable additional mobilization and ADSW periods but still employed as a GS.

    • No worries, Mark, you can buy your additional military service credit deposit without affecting your Reserve pension. That’s the benefit of the federal law waiver allowing you to collect both pensions.

      The reason you’re able to do this is because you’re paying for the credit.

  2. I just recently retired from the reserves last month and am employed as a GS in the FERS system. I did submit to buyback my initial active duty and am still paying thru payroll deductions. My question is, can I buyback any of the active duty time I did as a reservist although I’m now retired from the military? Also, can I still perform a Military Service Credit for my service academy time?

  3. My Question is.. I retired from Active Duty in 1996 after 17 years under TERA. I know TERA has a few ins and outs (I did not enter Federal Service soon enough (I started in 2001). I’ve heard that TERA retirements are treated similar to Reserve Retirements (since I did not do 20 years) and I may not have to waive my retirement pay. Rough calculations are that I would waive a small check and more than double my Federal Retirement. Will I have to waive my military retirement?

  4. This is wonderful news as I am approaching federal retirement and have been concerned about this. I am about to turn 56 and will be eligible for my reserve retirement is 4 years. What a blessing to be able to count on disability, a federal pensions AND my National Guard pension as well. Retirement may not be so bad.

  5. I am currently retired from the Marine Corps with 21 years of active duty. I am working a federal law enforcement job with the Bureau of Prisons.

    What is the earliest I can get a Federal law enforcement retirement? Is it 10 years? Because the maxim retirement age is 57 and the Min Retirement age is 50.

    • My husband retired from the military after 20 years. He receives a military retirement. He then spent 16 years working in civil service. He is now 62. Can he also receive civil service retirement for the 16 years.

      • Linda, I’m going to assume that you’re talking about an active-duty military pension. Please let me know if I guessed wrong.

        I can’t advise you about your spouse’s qualification to receive a civil service pension. However he receives his military pension while he’s working for the civil service, and that military pension continues when he retires from the civil service to receive his civil-service pension.

        In a few rare cases, it makes sense to waive an active-duty military pension to buy the military service credit deposit in a civil-service pension. In general this works for smaller military pensions (at the E-5 or E-6 rank) and larger civil-service pensions at GS-15 or SES.

        My friend Eddie Wills has also written more details about earning credit for military service with an active-duty pension while you’re working in the federal civil service. Your spouse may have already taken care of these opportunities.

    • Sorry, Allen, you’ve asked a good question but I’m not knowledgeable enough to have the answer. This post is intended for readers who are working toward both a military pension from the Reserve or National Guard as well as from civil service, and I’m focused on the military side of the question.

      There are very few situations where you’d want to waive your active-duty pension just to qualify for a federal civil service pension. They’d mainly involve already having an active-duty pension at the paygrade of E-6 or below and buying your military service credit deposit in a civil-service pension of GS-14 or higher.

      However there’s one benefit of the military service credit deposit which all military retirees should review:

  6. Doug,
    I separated from military as a LTC at 13 years. I am now in the process of joining the Air National Guard and use my 13 years of AD service for a Air National Guard pension. I presently work as a physician contractor in a military hospital and am paid very well but I have an opportunity to for a G.S. position where I will be paid 1/2 as much, but will have more job security. I am in my early 50s. What would be your recommendation in regards to converting into Civil Service with my 13 years versus my Air National Guard retirement? Thanks.


  7. My husband completed 18 years of military service and then got out. Is it possible for him to get a Civil Service job to complete his retirement? Is there any age limit?

    • Janet, this post is intended for members of the military’s Reserve and National Guard who are also federal civil-service employees. They can earn a pension in both the military and the federal civil service.

      If your spouse simply left the military and has no intention of joining the Reserve or National Guard (or returning to active duty with another service), then he can’t qualify for a military pension. However if he joins the federal civil service (and possibly some state civil services) then he could use his military time to buy his military service credit deposit from the civil-service retirement system.

      Once he’s joined the federal civil service then he can learn more about the military service credit deposit from former civil-service employee (and submarine veteran) Eddie Wills:

  8. Sir,

    I tried to buy my 13 years of active duty time though “Buy Back” program so it counts towards my civil service retirement. However, I was told from my HR that I may not be able to use my active duty time for my reserved military retirement after I use for my civilian service retirement. I hear two different information. Therefore, I contacted DFAS for clarification as well.
    Could you please clarify?

    Thank you.


    • Good question, Calseung73! The post lays out the rules for receiving a civil-service pension and a military Reserve pension.

      You already know that you can also use your active-duty time to buy your civil-service military service credit deposit. You can learn more about that system (and analyze its value to you) with Eddie Wills’ post from the “Related articles” links:

      It sounds like your HR might not have a handle on how your military active-duty time counts toward a Reserve retirement. Your Reserve point-count records should show that you’ve received one point for each of your days of active duty, along with 13 good years of Reserve retirement credit. You’ll continue to earn Reserve retirement points (and good years) until you reach 20 good years, at which point you’ll receive a Notice Of Eligibility for a Reserve pension. The 13 years of active duty count toward that pension, and you only need to earn seven more good years for the NOE.

      In other words, your active duty can be counted toward both your civil-service retirement and your Reserve retirement.

      • Thank you so much for the clarification. I spoke with 3 different customer service representative at DFAS and they said that I need to contact my unit finance for more information. I researched several different sources and found out that it seem like you got the correct information.
        Your information is very valuable to the veterans.

        Again, thank you.

  9. I retired 20 years Active Duty and my VA disability is 90%, Combat Related Service Connected was applied making my retirement tax free. Does this allow me to draw a Civil Service Retirement ?

    • Patterson James, you might be referring to these clauses in the FERS Handbook:
      “On account of a service-connected disability incurred in combat with an enemy of the United States; or

      On account of a service-connected disability caused by an instrumentality of war and incurred in the line of duty during a period of war…”

      This is a good time to consult with your OPM rep and talk to a JAG. These sections of the Handbook may be referring to a disability retirement (Chapter 61 of Title 10 U.S. Code) which is different from an active-duty retirement and also different from receiving compensation for a VA disability rating.

      In other words I’m not sure about the civil service interpretation of the word “disability” in the FERS handbook, and I strongly recommend checking with a lawyer.

  10. Ok, i am in a little different place. I served on Active Duty for 10.5 years. i got a federal job and worked for another 10 years as civil service. I brought back my active duty time while a civil service and now i have went back on Active duty. So how will my retirement workout if i retire from active military and then go back to the civil service and retire again. Can i receive two federal retirements

    • Sean, that’s a very good question and the answer is outside my circle of competence. You need to consult with a JAG (or a civilian lawyer) who understands OPM regulations. You could also e-mail Eddie at ( to see if he’s heard the question before.

      Of course you can receive two federal pensions. You’ve earned both of them. The question is whether you can continue to receive the benefit of the military service credit deposit in your federal pension without having to waive a portion of your military pension.

      I see three possibilities:
      1. OPM regulations give you the credit for the first 10.5 years (because you were entitled to it at the time) and you elect not to take the credit for the latter 9.5 years (because you’d have to waive your military pension). You’d still apply for your additional FERS credit for annual leave:
      You’d retire to both pensions. It might be perfectly legal under OPM regs, although it’s certainly rare. The question is whether OPM actually has any regs to address this situation.

      2. OPM regulations determine that you’re no longer eligible to benefit from your military service credit deposit for the first 10.5 years and they return your money. You’d still apply for whatever FERS credit you can get for annual leave (the same post linked in #1).
      You’d retire to both pensions, although your FERS pension is smaller because you were no longer able to use the military service credit deposit.

      3. OPM regulations determine that you’re now going to have to waive a portion of your military pension in order to keep the military service credit deposit from the first 10.5 years. You’d have to negotiate a solution, because I think that an active-duty pension now is worth more than buying a larger FERS pension later.
      You’d retire to both pensions, although your military pension is smaller because you had to waive a portion of it.

      You might possibly find some way to apply for a waiver to enable #1.

      Again, please consult Eddie and a lawyer who understands OPM FERS regulations with military service.

  11. Great article!!! I do have another question though. I’m also Federal Service and currently on ADSW as a naval reservist. I already set up a military deposit for my previous AD and am going to make an adjustment to continue crediting my current ADSW. Question I have though is how does the current Blended Retirement System figure in to all this?

    • Thanks, Mark, and your question has a simple answer! It’s all the same.

      The only changes to your military pension are the different multiplier (2.0% per year for BRS instead of High Three’s 2.5%) and your DoD BRS matching contributions to your TSP.

      You still earn the same number of days of active duty for your ADSW, and your military service credit deposit amount is still based on those days. None of those OPM civil-service procedures were changed by the DoD BRS.

  12. Can his 14 years of active duty still be used towards guard/reserve retirement.

  13. Am I confused? You seem to imply that you cannot receive a military and a civil service pension? Now, I know for a fact that you can receive a military pension and a civil service paycheck because I have many friends currently doing so. I always assumed that they would receive both pensions as well. Is that not true? Keep in mind that these are active duty retirees had to start from scratch in the civil service after they retired from active duty.

    • I’m not implying that at all, Chris. The post is about the sizes of those pensions and how a military pension is affected by taking the FERS military service credit deposit.

      The military service credit deposit is a bad deal for active-duty military retirees (although they should still take the adjustment to their federal Service Computation Date). I don’t know any active-duty military retirees who have applied for the military service credit deposit because it would halt their active-duty pension while they were in the federal civil service. Instead, active-duty military retirees should choose to continue to receive their active-duty pension and should not buy into the military service credit deposit. The result is that their FERS pension is based only upon their years of federal civil service. Review bullet #2 in the post.

      The FERS military service credit deposit is a great deal for Reserve and National Guard retirees. The reason that FERS retirees should still buy their Reserve/Guard military service credit deposit is because there’s a specific exemption in the FERS regulations allowing them to do so while still receiving their full Reserve/Guard pension. As a result they still receive their Reserve/Guard pension (beginning at age 60 or perhaps a little earlier) and they receive a larger FERS pension. Review bullet #3 above.

  14. Military or civil service, historically the most attractive features of both systems has been the automatic COLA or yearly inflation adjustments. But what if “inflation” or COLA is an economic condition of the past. 2017 will mark the 2nd year in row, 4 out of the last 7, where no COLA will be provided to either SS or the traditional military retirement system. One can argue the govt, and Fed is still using outdated or ineffective CPI measures, that still stress finished goods and commodities over services. Case in point is 2 types of services retirees continue to consume more and more, heath care and housing/rent where year over year “inflation” still advances at 5-7% year over year.

    Many feel that like Japan of the last 30 years, the developed West may be in a prolonged period of dis-inflation, or deflation. Where almost a decade of zero interest rate policy, negative bond yields, falling productivity spell an extended period of stagnation. And if it is true there is a mismatch or at least mis-measurement of true inflation, then the value of the traditional military, civil service pension erodes year after year, and over 4 to 5 decades of a military retirement, the actual value or income security year over year is greatly diminished. And if that is the case the only real alternative in retirement security is to save more, lots more. Which brings another issue, how does one make money in a negative interest rate, yield environment, where the individual retiree or saver goes further out on the risk curve. Those economic periods usually end very badly. Interesting times indeed.

    Comment? Question? What's on your mind?
