Information About Service Credit Payments
Federal Employees Retirement System
Detach this sheet before filling out the application and save it for your records.

Read this information carefully before filling out the attached application.

Who Should Use this Application?
You should use this application if you are covered by the Federal
Employees Retirement System (FERS) and you want to pay for civilian
service so that you can receive retirement credit for the service. Use this
application even if you transferred to FERS and want to pay for service
which will be credited under Civil Service Retirement System (CSRS)
rules.
If you are not currently working as a Federal employee under FERS, but
you had been covered under FERS and had at least 5 years of paid
creditable civilian service at the time you left FERS covered employment,
you may also use this application to pay for additional unpaid civilian
service that you performed.
You should also use this application to pay a deposit for your military
service performed after December 31, 1956, if you are currently in a
position covered by FERS.
If you are under the Civil Service Retirement System, use Standard Form
2803, Application to Make Deposit or Redeposit, to apply to pay for
service. You can obtain that application from your Human Resources
office or from our website at www.opm.gov/forms.

Requesting Additional Information About Past Service
If you are currently a Federal employee and you want to know whether:
(1) a period of service will be creditable for retirement; (2) retirement
deductions were withheld from your pay; or (3) you received a refund for a
period of service, ask your agency for assistance. If you decide to pay for
some periods of service, but not others, discuss this with your agency's
benefits office. It may be more advantageous for you to pay for certain
periods of service instead of others. There are different types of service
and different rules relating to how the service may be credited in
determining when you can retire and in determining the amount of your
annuity. If you are not currently a Federal employee, you can call the
Office of Personnel Management (OPM) on 1-888-767-6738 (TTY:
1-800-878-5707) Monday through Friday from 7:30 AM to 7:45 PM Eastern
Time, or write to:
Office of Personnel Management
Retirement Operations Center
P.O. Box 45

Boyers, PA 16017-0045

to ask for the information you need.

Credit for Military Service Performed After
December 31, 1956
To make payment for military service performed after December 31, 1956,
refer to the instructions on SF 3108A, Application to Pay Military Deposit,
which is part of this package. Only current FERS covered employees may
apply to pay for military deposits.

Credit for Civilian Service
Unless you elected to transfer to FERS under conditions that permit CSRS
rules to apply to some of your service, your service will be subject to FERS
service credit rules. What follows is a general overview of the FERS
service credit rules. If you elected to transfer to FERS and are entitled to
have CSRS rules apply to part of your FERS benefit, OPM will bill you the
appropriate amount of deposit for the service subject to CSRS rules. You
can obtain information about the CSRS rules and CSRS deposit rates from
your agency's benefits office or from SF 2803, Application to Make Deposit
or Redeposit, Civil Service Retirement System. Your agency should be
able to provide you with a copy of that form or you can obtain it from our
website at www.opm.gov/forms. But remember, use the SF 2803 for
informational purposes only.

General FERS Rules
You can pay a civilian deposit/redeposit for:
• Any period of creditable civilian service performed before 1989 during
which no retirement deductions were withheld from your pay.

•

Any period of civilian service during which CSRS deductions were
withheld from your pay and were then refunded to you based on an
application you filed before you became covered by FERS, if the service
will not be credited under CSRS rules.

•

Certain periods of civilian service performed under other retirement
systems for Federal employees (that is, other than CSRS or FERS).

•

Any period of Peace Corps or VISTA volunteer service (excluding
training time) regardless of when the service was performed provided
that it was followed by a period of creditable FERS covered service.

•

If you were employed under FERS on or after October 28, 2009, you
can pay a civilian redeposit for any period of service under FERS for
which you received a refund of your retirement deductions.

You cannot pay a civilian deposit/redeposit for:
• Any period of service under FERS for which you received a refund of
your retirement deductions based on an application you filed after you
had been covered by FERS, if you were not employed under FERS on
or after October 28, 2009 .

•

Temporary or intermittent service which you performed after 1988,
unless a deposit is allowed by a special provision of law. Temporary
service means an appointment which is limited to one year or less.
Intermittent service means an appointment with no scheduled tour of
duty.

•

Any other service which is not creditable under FERS.

•

Periods of leave without pay. (But a military deposit may be allowed for
a period of leave without pay from a FERS covered position while
serving on active military duty.)

•

Time covered by a lump sum leave payment.

The amount of the deposit payment for most civilian service is 1.3
percent of your basic pay for the service, plus interest. The 1.3 percent
rate applies regardless of whether deductions would have been taken at
that rate, if they had been taken at the time the service was performed.
You must pay the total amount due for each separate period of service
before you can receive credit for it in your annuity. A separate period of
service is a period of civilian service that is not interrupted by a break in
service of more than three days.
If you pay for part-time service, you will receive credit for the number of
hours in your official tour of duty - e.g. 20 hours per week. If you worked
more than your official tour of duty, attach a statement with the name of the
agency where you worked, the beginning and ending dates of each period
of service, your grade and job title, and the number of hours worked per
week. If available, attach copies of any earnings statements which show
the number of hours worked.

The amount of the deposit payment for Peace Corps or VISTA
volunteer service is the percentage of your basic salary shown below,
plus interest.

If you are repaying a refund of FERS deductions, paying a deposit for
certain non-covered service that became subject to mandatory Social
Security tax as the result of the Social Security Amendments of 1983,
or you are repaying a refund of deductions for CSRS Offset service
which will be credited as FERS service, or you are waiving credit for
service under the Foreign Service Pension System or the Federal
Reserve Board's Bank Plan, in order to credit the service under FERS,
the amount of the deposit or redeposit payment is the amount that would
have been deducted from your salary under FERS, plus interest. The
deduction rate for most FERS service is listed below. For some service
subject to special retirement provisions, however, the deduction rate is
0.5% higher than the rate shown in the chart.

Interest is computed from the midpoint of each period of service included in
the computation, or from the date the refund was paid. Interest accrues
annually on the outstanding balance, and is compounded annually until the
outstanding balance is deposited. Interest is charged to the date of
deposit/redeposit or commencing date of annuity, whichever is earlier.
(Interest on Peace Corps/ VISTA service credit deposit begins to accrue on
October 1, 1995, or 2 years after the date you first became a Federal
employee, whichever is later.)
Interest is charged at the following rates:
Before 1948
4%
1948 - 1984
3%
1985 - Present
A variable rate determined by the Department of
Treasury. The variable rate for any year equals the
overall average yield to the fund from retirement
securities during the preceding fiscal year.
Payment is optional. You do not have to pay if you do not want to do so.

If you were employed under FERS on/after October 28, 2009 and do
not pay a redeposit for a period of refunded FERS service or a deposit
for refunded CSRS service that is being credited under FERS rules,
you will not receive credit for it in the computation of your annuity,
however, you will receive credit toward your eligibility to receive an
annuity and computing your average salary. If you were not employed
under FERS on/after October 28, 2009, you cannot pay a redeposit for
a period of refunded FERS service and the service will not be used to
compute your benefit, toward your eligibility to receive an annuity or in
computing your average salary.
If you were not employed under FERS on/after October 28, 2009, and
do not pay a deposit for a period of refunded CSRS service that is
being credited under FERS rules, you will not receive any credit for it
toward retirement, including your eligibility to receive an annuity and
computing your average salary.
If you do not pay for a period of FERS service where no FERS
deductions were withheld from your pay, you will not receive any credit
for it toward retirement, including your eligibility to receive an annuity
and computing your average salary.

Payment for civilian service can be made by • You while you are employed by the Federal government and covered
by the Federal Employees Retirement System (FERS).

•
•

You when you retire. The Office of Personnel Management (OPM) will
automatically compute any amount payable when you retire and give
you an opportunity to pay it.
You, after you leave the Federal government, provided you are eligible
for a deferred annuity because you have at least five years of paid
civilian service when you leave. If you are not eligible for a deferred
annuity, but you have at least 5 years of combined paid and unpaid
civilian service, you may pay a deposit for the unpaid service provided
you apply before leaving FERS covered service.

•

Your surviving spouse if you die as an employee or separated
employee and your spouse is eligible for a survivor annuity benefit.
OPM will automatically compute any amount payable and give your
spouse an opportunity to pay it.

Payment by you or your spouse must be completed before final processing
of retirement or survivor benefits.
Payment cannot be withdrawn unless (1) you become eligible for and
obtain a refund of all your FERS retirement deductions, or (2) you retire and
are eligible to choose an alternative annuity and lump sum payment
of your retirement deductions. If you make payment, and later receive a
refund, you cannot redeposit the money again. This applies to refunds of
payments for both civilian and military service. If you do not complete
payment for a period of service before your annuity begins, OPM will refund
the partial payment, plus interest, at the time of retirement.

How to Apply and Make Payment
If you are a Federal employee, send your completed application to your
department or agency because they must certify it. Please do not file an
application if you plan to retire within six months. OPM will give you an
opportunity to make payment when it computes your annuity.
If you are not currently a Federal employee, send your completed
application directly to:
Office of Personnel Management
Retirement Operations Center
P.O. Box 45

Boyers, PA 16017-0045.

Instructions for making payment, together with a bill for the amount due,
will be sent to you as soon as OPM processes your application.
Installment payments of at least $50.00 are acceptable. However, since
interest is charged on the unpaid balance, you have to pay additional
interest if you make installment payments.
Direct Debit Payments can be made from your checking or savings
account. If you want to authorize direct debit payments, complete form RI
16-28, Authorization for Direct Payments, which is found on our website at
www.opm.gov/forms. If you prefer, you can call us on 1-888-767-6738
(TTY: 1-800-878-5707) and we'll send you a copy of this form.

2. Employee's Acknowledgment of Understanding of Military Service Credit and Deposit Rules
I am currently employed in a position where deductions for the Federal Employees Retirement System (FERS) are being deducted from my
salary, and I wish to pay the deposit necessary to obtain credit for my military service after 1956. I understand that I must pay the entire
deposit to my employing agency before separation for retirement. I further understand that the military deposit cannot be deemed paid at
retirement if I am eligible for and elect an alternative annuity. If I do elect the alternative annuity upon retirement, any completed military
deposits made to the Fund will be refunded to me along with any other retirement contributions or payments I made to the Fund. Once I
complete the deposit in full, I understand that it can only be refunded to me if I become eligible for a refund of my retirement contributions or
retire without waiving my military retired pay (if any).
I understand that for any given full period of military service that I have performed, if I do not complete the deposit for that full period of military
service, any payments I made that were applied to that full period of military service will be refunded to me when I retire or when I become
eligible for a refund of my retirement contributions. I also understand each of the following service credit rules and how they apply to any given
full period of military service that I have performed for which I have not completed the military deposit:

• For each period of military service performed after 1956 that is subject to FERS rules, the post-1956 military service will not be used to
compute or establish title to a FERS annuity if I do not complete the deposit before I separate for retirement.

• For each period of military service performed after 1956 that is subject to Civil Service Retirement System (CSRS) rules in a CSRS
component of my FERS annuity:

 If the first time I worked in a position where CSRS deductions were withheld from my salary was on or after October 1, 1982, the
post-1956 military service will not be used to compute or establish title to a FERS annuity if I do not complete the deposit before I
separate for retirement.

 If the first time I worked in a position where CSRS deductions were withheld from my salary was before October 1, 1982, the
post-1956 military service will not be used to compute my annuity at age 62 (or when I retire, if I retire after age 62), if I am eligible
for Social Security benefits at that time.
Finally, I understand that payment of this deposit will not make my military service creditable if it is otherwise not creditable under FERS or
CSRS. I realize that the Office of Personnel Management (OPM) is solely responsible for adjudicating and administering civil service retirement
benefits. I understand that OPM will determine if my military service can be credited in my FERS retirement when I apply for my retirement
benefits.

Information For Employee

Employee Instructions for Applying to Pay Post-1956 Military Service Deposit
• Complete sections 1-11 on the front of the SF 3108, Application to Make Service Credit Payment.
• Complete this form, SF 3108A, Application to Pay Military Deposit for Military Service Performed After December 31,1956.
• Include a copy of your DD 214, Report of Transfer or Discharge, or equivalent record to verify your military service. If copies of the DD

214 are not available, you should complete form SF 180, Request Pertaining to Military Records, and send it to the appropriate address
(found on the form) to verify your military service. You can obtain this form from your employing agency.
• Attach documentation of military basic pay to this application. (See below)
• Give the completed SF 3108, SF 3108A, and documentation noted above to your employing agency. Your agency will compute the

military deposit you owe and give you instructions for paying the deposit.

Employee Instructions for Completing this Form (SF 3108A)
• Complete item 1 (Information About Employee's Military Service) by providing the branch of the military in which you served (e.g. Army,

Navy, etc.) and the dates of your military service. If you have more than one period of military service, make a separate entry for each
period of military service you performed. Note, a period of military service includes consecutive periods of service where there is no
break in service. For military purposes, a 1-day break separates service into two periods. Your agency will complete the section relating
to the retirement system, the alternative deposit computation rules, and the interest accrual date.
• Read the information in item 2 and then sign and date the form, and provide a telephone number where you can be reached during

the day, at the bottom of item 2.

To Obtain Documentation of Military Basic Pay
Basic pay earnings may be documented by either of the following methods:
• Actual pay records from the military service. Your agency can tell you what military pay records are acceptable for documenting

actual military earnings.
• Estimated earnings, if you do not have official records of military earnings for the entire period of service. To obtain these estimated

earnings from the military, use RI 20-97, Request for Estimated Earnings During Military Service. You can obtain this form from your
employing agency or from our website www.opm.gov/forms. You must attach a copy of your DD 214 for the period of military service
and any available records of pay and promotions. If the alternative deposit calculation under USERRA applies to a period of military
service, you should check with your agency for special instructions for requesting estimated earnings if you received civilian pay (military
leave, annual leave) during your period of military service.
The following records may not be used to document earnings:
• Earnings statements from tax records. (They include allowances as well as basic pay.)
•

Social Security earnings statements. (They include allowances as well as basic pay and also reflect only military basic pay earned up to
the Social Security maximum wage base for withholding.)

Information For Employing Agency
Agency Instructions: The employing agency (or organization designated by the agency to administer the personnel records of the
employee) must complete the Agency Use Only section for every application before the action is processed through payroll. For each period
of military service listed by the employee in Block 1, the employing agency must indicate which retirement plan rules are applicable to the
particular period of service by placing a check mark in the appropriate block under Retirement System Rules. (A check mark in the CSRS
column indicates that the military service will be credited in a CSRS component of the FERS annuity and the deposit will be computed under
CSRS rules. A check mark in the FERS column indicates that the military service will be credited under FERS rules and that the deposit will
be computed under FERS rules.) The agency must also indicate if the period is subject to the special comparative deposit calculation rules
specified in the Uniformed Services Employment and Reemployment Rights Act (USERRA) of 1994, as amended, by checking the
appropriate block (Yes or No) under the Does Alternative Deposit Calculation Under USERRA Apply? column. Do not leave that column
blank. And, for each period of military service listed, the agency must provide the interest accrual date for the military deposit. Finally, an
authorized agency official should sign and date the certification section.
