Benefits Administration Letter

Number 18 - 101 Date: 05/2/2018

Subject: Annual Changes 

Background 

Each year, we publish a Benefits Administration Letter (BAL) with updated information 

that changes annually, such as interest rates and cost-of-living adjustments. This BAL 

contains the figures for 2018. 

Cost-of-Living Adjustments

Many people who receive monthly payments from the Civil Service Retirement System 

(CSRS) or the Federal Employees Retirement System (FERS) will receive a cost-ofliving adjustment (COLA) effective December 1, 2017. The increase is paid in their 

January 2018 annuity payment. The maximum increase is 2% for CSRS and FERS 

annuitants. 

NOTE: The minimum COLA increase is $1.00. Even if the full COLA rate of 2% or a 

prorated COLA would result in the annuity rate not increasing, $1.00 is still added to 

the monthly rate. 

All eligible annuitants who have been retired at least 1 year will receive the full COLA, 

or maximum increase. FERS COLAs apply to the retiree’s basic annuity only (not the 

annuity supplement). For survivor annuitants, the COLA applies to both the basic 

survivor annuity and supplementary annuity. In addition, FERS COLAs generally do not 

apply to annuitants who are under age 62 as of December 1, 2017; exceptions are noted 

in title 5. CSRS COLAs apply to all annuities, regardless of the age of the annuitant.

Pro-rated COLAs are payable on annuities having a commencing date from December 1, 

2016, through November 30, 2017. The CSRS and FERS COLAs are payable on 

annuities with commencing dates no later than November 30, 2017. The proration is 

based on the number of months between the annuity commencing date and the effective 

date. 

Annuitants will receive one-twelfth of the applicable increase for each month they 

received an annuity. For survivor annuitants (other than children) of deceased annuitants, 

the proration is determined by the date the annuity was first payable to the deceased. For

survivors of deceased employees, the proration is determined by the commencing date of the 

survivor annuity. COLAs on children’s annuities are never pro-rated. The following table 

shows the prorated percentage increase according to the month in which the annuity 

began.

PRORATED CSRS and FERS COLAs EFFECTIVE 12/1/2017 

Increase in Children's Benefits 

CSRS COLA rates apply to children’s benefits regardless of whether the child’s parent 

was under CSRS or FERS. However, children’s benefits under FERS are offset by 

benefits payable under Title II of the Social Security Act for all children of the deceased. 

In most cases, the Social Security benefit exceeds the FERS benefit which results in no 

FERS benefit being paid. The following rates apply from December 1, 2017, through 

November 30, 2018. 

When the child has a living parent who was married to the deceased employee or retiree, 

the benefit payable to that child is the lesser of: 

• $ 522 per month per child; or 

• $1,566 per month divided by the number of eligible children (if over 3). 

When the child has no living parent who was married to the deceased employee or 

retiree, the benefit payable to that child is the lesser of: 

• $ 627 per month per child; or 

• $1,881 per month divided by the number of eligible children (if over 3).

FERS Basic Employee Death Benefit 

The $15,000 portion of the FERS Basic Employee Death Benefit is adjusted by the CSRS 

COLA. The CSRS COLA, effective December 1, 2017, increases the Basic Employee 

Death Benefit for an employee who dies on or after December 1, 2017, and before 

December 1, 2018, to half of his/her final annual pay (or average pay, if higher), plus 

$33,072.03. Chapter 70 of the CSRS and FERS Handbook has detailed information on 

the Basic Employee Death Benefit (BEDB). 

The surviving spouse must elect whether to receive the BEDB in one payment or in 36 

monthly installments. The current factor used to determine the monthly installment is 

.0299522. Additional information on this can be found at 

http://www.gpo.gov/fdsys/pkg/FR-2014-11-07/pdf/2014-26469.pdf in the November 7, 

2014 Federal Register. 

 

Interest Rate for Service Credit Payments, Refunds, and Voluntary Contributions 

The interest rate that applies to both CSRS and FERS for 2018 is 2.125%. 

Salary Cap 

Employees who are subject to a salary cap pay retirement deductions on the capped 

amount and the capped amount is used to compute an employee’s high-3 average pay. 

The salary information on the SF-50, Notification of Personnel Action, should reflect the 

capped amount and not the salary that would have been payable without the cap. 

Reminder Regarding Military Deposits 

Use the table below to compute military deposits for service during those years and for 

the 2018 rates. Chapter 23 of the CSRS and FERS Handbook has detailed information on 

Service Credit Payments for Post-56 Military Deposits and BAL 03-105 provides an 

explanation of the alternative method for employees under the Uniformed Services 

Employment Reemployment Rights Act (USERRA).

Employees who want to pay deposits for military service they performed during any of 

these years need to request that the military pay center provide year-by-year earnings so 

that you can compute deposits correctly.

This is a reminder that all military deposits have to be paid in full to the employing 

agency prior to the employee’s separation for retirement.

Reminder Regarding Waiver of Military Retired Pay 

Employees requesting to waive military retired pay should submit their request directly to 

the Defense Finance and Accounting Service at the following address 30 days before 

their planned retirement date to avoid delay in the finalization of their retirement. A copy 

of this request must be attached to the retirement application:

 Fax: 1-800-469-6559 

Chapter 22 of the CSRS and FERS Handbook (Chapter 22, Section 22 A4.1-2) contains 

information that must be provided and sample wording that can be used. 

Present Value Factors

There has been no change to the present value factors for 2018. 

The last revision for the present value factors went into effect on October 1, 2015 and 

were published in the Federal Register, volume 80, No. 64 on April 3, 2015. 

CSRS factors can be accessed at 

https://www.gpo.gov/fdsys/pkg/FR-2015-04-03/pdf/2015-07677.pdf

FERS factors can be accessed at 

http://www.gpo.gov/fdsys/pkg/FR-2015-04-03/pdf/2015-07694.pdf. 

OPM uses present value factors to compute reductions to: 

• CSRS and FERS retirees’ benefits when the retiree elects the Alternative Form of 

Annuity; 

• CSRS and FERS benefits with a CSRS component when the retirees elect to 

credit refunded service that ended before March 1, 1991, without paying the 

deposit owed for the service; 

• CSRS and FERS benefits when the retirees marry after retirement and elect to 

provide survivor annuity benefits; 

• Retirees’ benefits when the retirees elect to credit Non-Appropriated Fund 

Instrumentality (NAFI) service for retirement purposes under Public Law 104-106 

or Public Law 107-107; and, 
 Retirement Services

• Retirement benefits for individuals with certain types of retirement coverage 

errors who can receive credit for service by taking an actuarial reduction under 

the provisions of the Federal Erroneous Retirement Coverage Correction Act. 

OPM uses discount factors to compute the reduction to annuity benefits when retirees 

elect to credit their NAFI service. 

Significant Social Security Figures for 2018 

 

On November 27, 2017, the Social Security Administration published a Fact Sheet that 

listed 2018 figures that are significant for retirement matters. You can find that Fact 

Sheet on the Social Security Administration's Internet site, at

https://www.ssa.gov/news/press/factsheets/colafacts2018.pdf. We have included some of 

the figures here for your convenience. 

 

Social Security Maximum Wage Base: The Social Security maximum taxable wage for 

2018 is $128,400. 

 

Bend Points: The dollar amounts, or bend points, used in the benefit formula for workers 

who become eligible for benefits in 2018, and in the formula for computing maximum 

individual benefits for 2018, are $895 and $5,397. 

 

FERS Retiree Annuity Supplement Earnings Limit 

 

The Social Security earnings limitation is $17,040 a year for 2018. Any FERS annuitant 

who is receiving a FERS annuity supplement (unless he or she is under the minimum 

retirement age and retired under one of the special provisions for law enforcement 

officers, firefighters, air traffic controllers, or military reserve technicians separated for 

loss of military membership) will have his or her annuity supplement offset in 2018 by 

$1.00 for every $2.00 over this amount earned in 2018. 

 

Increase in Age for Full Social Security Benefits

 

Legislation passed in 1983 provided that the age for receiving full Social Security 

benefits will gradually increase from 65 to 67. The first increase took effect in January 

2001. It affects workers born in 1938 or later. More information on this change is 

available on Social Security's web site at www.ssa.gov. 

 

Note: This change does not affect the entitlement of any person who is age 62 to receive 

reduced benefits if he or she has sufficient Social Security credits to receive a benefit.

Thrift Savings Plan (TSP) Deferral Limit 

The Internal Revenue Service annual limit on elective deferrals remains unchanged at

$18,500 for tax year 2018. For purposes of the TSP, the term "elective deferrals" means 

the maximum amount that employees can contribute to their thrift accounts. 

In addition, TSP participants that are age 50 or over can make tax-deferred “catch-up” 

contributions from their basic pay to their TSP accounts. These contributions are a 

supplement to the participant’s regular employee contributions and do not count against 

the Internal Revenue Code’s elective deferral limit. Additional information is available 

at: https://www.tsp.gov/PDF/formspubs/oc91-13.pdf. The catch-up contributions have 

their own annual limit and eligibility criteria. The limit remains unchanged and is $6,000 

for 2018. Additional information is available at: 

https://www.tsp.gov/PDF/formspubs/oc03-03.pdf and
