A. Cover Letter 

What is the Cover Letter? 

The cover letter is the first document in the decision package. You will include a cover 

letter in every decision package regardless of the error type. However, the sample cover 

letter that follows is just that, a sample. You can change this letter to suit your 

employee’s and your agency’s needs. The only paragraph required is the last paragraph 

providing the default information for FERCCA elections. 

You should find this letter meets your needs except in the employee contact information 

section. Your agency may have procedures for contacting employees. If that is the case 

you’ll want to follow your agency’s procedures.

Offset: Election Between FERS and CSRS Offset 

How do I complete the Cover Letter? 

As you read through the sample cover letter you will see more information is needed in 

order for it to be complete. The numbering on the left is to make it easier to understand 

the instructions in this section. 

Section 1: This section is self explanatory. One item to note is the date. When you read 

the last paragraph of the cover letter you will see that the employee’s right to a waiver of 

the six month time limit to make their FERCCA election is based on the date of the cover 

letter. 

Section 2: You will find a sentence that says “Within the next 15 business days your 

agency retirement counselor will contact you...” You can adjust that number to any 

number that is appropriate for your employee and your agency. You will also need to 

provide the name of the agency retirement counselor if it is different from the person who 

signs the letter. If the person signing the letter is the retirement counselor just change this 

sentence to read “I will contact you...” 

Section 3: You enter the work phone and email you have for the employee. If you do not 

have this information delete this section and ask the employee to provide the agency with 

their preferred method of contact in the next paragraph in the cover letter. Provide the 

contact information of the agency retirement counselor who will be assisting the 

employee in this section. 

Section 4: You must provide your agency’s name and your agency’s address. The 

address is very important because this is how the employee will provide you with copies 

of their signed FERCCA election form. Also, if they need to submit a waiver of the six 

month time limit to make a FERCCA decision they will do it using this address. You 

may want to provide the employee with your email and fax number as well, in case the 

employee wants an additional way to send his election back to you. 

Section 5: Include the employee’s name on the second page either at the top of the page, 

at the end, or in both places. There is a guide titled “Should you stay in FERS?” which is 

for employees choosing between FERS and CSRS Offset when they were erroneously 

placed in FERS. The guide is available at OPM’s web site at 

www.opm.gov/asd/pdf/2002/02-1036.pdf or www.opm.gov/asd/htm/2002/02-1036.doc

Dear ##name##: 

Previously, we notified you that a review of your official personnel records showed a 

retirement coverage error. We found you were erroneously placed in the Federal 

Employees Retirement System (FERS) when you should have been placed in the 

Civil Service Retirement System (CSRS) Offset. As a result of this error, you are 

being given an opportunity to choose between CSRS Offset or FERS retirement plans 

as provided for in the Federal Erroneous Retirement Coverage Correction Act 

(FERCCA) legislation and Office of Personnel Management (OPM) regulations. 

The material in the enclosed election summary package is designed to help you make 2 an informed choice about which option to elect. For example, the package includes a 

comparison of your retirement benefits calculated under each option as well as a 

comparison of your Thrift Savings Plan (TSP) benefits under the two options. Also 

included are the assumptions we used in preparing these estimates. 

We ask that you review the material in this package carefully before making a 

decision. Within the next 15 business days, ##your agency retirement counselor## 

will contact you by telephone to confirm that you have received and reviewed the 

package and answer any questions you may have about your election options. The 

counselor is prepared to assist you in making a decision but will not advise you on 

which option to choose. 

The contact information we have on file for you is: 3

you in this process. Please forward your correct contact information to ##email and 

phone number of counselor who will provide assistance##. 

Your election is irrevocable once it is received by ##your agency name##. Once

4 you have received sufficient information to make an informed decision, please 

complete the applicable forms and return them as soon as possible to: 

##your agency’s mailing address goes here and/or email and/or fax## 

You will have six months from the date of this letter to elect your coverage option. If 

you fail to make an election before the time limit has expired, your default retirement 

coverage will be FERS. We can waive the time limit for making an election if you 

request such a waiver in writing. We would have to determine that you exercised due 

diligence, but could not make an election within the time limit because of 

circumstances beyond your control. These circumstances need to be well 

documented. In six months if you need to request a waiver please submit it in 

writing with any supporting documentation to the address provided above. 

Sincerely,

B. Annuity Estimates and Thrift Savings Plan Estimates 

Annuity Estimates 

Prepare the annuity estimates as you normally would. It is important to include a service 

history in the estimate for the employee so that they can understand where the FERCCA 

error occurred. If the person has deposits and/or redeposits that fall under the FERCCA 

actuarial reduction rules then you will need to follow the instructions in Section C 

Comparison Sheets. FERCCA actuarial reduction calculations may already be included in 

your estimates if your calculator provides them. Provide the employee with the completed 

comparison sheets or you can provide the actual estimates to the employee if you choose to 

or if they request it. 

Thrift Savings Plan (TSP) Estimates 

The TSP estimates for CSRS Offset will need to reflect the employees balance if the agency 

contributions both automatic and matching and their earnings were removed from the 

account. The FERS TSP balance remains the same as the employee’s current TSP balance.

Offset: Election Between FERS and CSRS Offset 

C. Retirement System Comparison Sheets 

What are the Retirement System Comparisons Sheets? 

The Retirement System Comparison Sheets have been designed so the employee can 

compare at a glance the pertinent parts of their annuity estimates rather then have them 

decipher the annuity estimates for themselves. If you do two annuity estimates for an 

error type, one showing deposits and redeposit paid, and one without the deposits and 

redeposits paid the employee would have a lot of annuity estimates to try and understand. 

Employees may have difficultly figuring out their annuity estimates since these are 

documents they do not normally have to interpret. This is why the Retirement System 

Comparison Sheets have been designed. You can use these sheets as part of the decision 

package and attach the annuity estimates so the employee can look at them if they need 

to. 

How do I complete the Retirement System Comparison Sheets? 

Use the annuity estimates you prepared and the instructions provided in this section to 

prepare the Retirement System Comparison Sheets. 

On the following pages are two Retirement System Comparison Sheets, one sheet 

compares the employee’s annuity amounts with deposits and/or redeposits not paid; the 

other compares the employee’s annuity amounts with the deposits and/or redeposits paid. 

The chart below provides instructions on how to complete the comparison sheet with 

deposits and/or redeposits not paid:

making a decision between CSRS Offset and FERS.

BAL 10-104: Appendix VI: Erroneous FERS Coverage Employee Belongs in CSRS 

Offset: Election Between FERS and CSRS Offset 

FERCCA FACT SHEET 

CSRS OFFSET FERS 

Annuity 

Benefits 

With CSRS Offset coverage, you earn 

retirement credit while also earning credit 

under Social Security. It offers you the benefit 

of an unreduced annuity computed under the 

CSRS formula until you become eligible for 

Social Security at which time your CSRS 

annuity will be reduced, or offset, by the value 

of the Social Security benefit based on the 

amount of your service that is creditable as 

CSRS Offset service. The offset will apply if 

you are eligible for Social Security even if you 

decide to postpone receiving Social Security 

benefits. (If you do not become eligible for 

Social Security benefits, there is no offset). 

This does not mean that you lose any 

monetary benefit. 

The earliest an employee can retire under 

CSRS Offset for a regular voluntary retirement 

is 55. 

FERS provides a basic retirement benefit 

and a Social Security benefit, disability and 

survivor benefits. The basic benefit for a 

regular voluntary retirement is 1% of the 

high-three average salary times the total 

years of creditable Federal service. 

Depending on the type of retirement you are 

eligible for you may receive an annuity 

supplement until you reach age 62. The 

supplement approximates the Social 

Security benefits you earned while working 

for the Government. 

The FERS Minimum Retirement Age (MRA) 

is based on your year of birth. 

If you were born: Your MRA is: 

Before 1948 55 

1948 55 and 2 months 

1949 55 and 4 months 

1950 55 and 6 months 

1951 55 and 8 months 

There are two formulas that are used to 

determine the amount of a CSRS annuity 

offset. The smallest amount is used as the 

offset. Here are the two formulas: 

Formula 1: 

Social Security Total Years of Offset Service

 benefit X 40 

Formula 2: 

Social Security monthly benefits with Federal 

Offset Service 

--- (minus) . 

Social Security monthly benefit without Federal 

Offset Service. 

Each year, the CSRS Offset annuity, and the 

Social Security payments are adjusted by cost 

of living increases that match the Consumer 

Price Index.

F. Preparing for your Counseling Session (for employees) 

On the following page is an information sheet that can be included in the decision 

package so the employee can prepare for his or her FERCCA counseling session. This 

information sheet was created to assist the employee in thinking about what to ask the 

Human Resource Specialist during their initial FERCCA counseling session. The 

counseling session is explained in the FERCCA cover letter. 

15
 

BAL 10-104: Appendix VI: Erroneous FERS Coverage Employee Belongs in CSRS 

Offset: Election Between FERS and CSRS Offset 

Preparing for Your Counseling Session 

For employee in FERS who should be CSRS Offset 

Before the counselor calls, you should carefully read all the material in the package and 

check to ensure all of the information is correct. 

 Review your name, address, social security number, etc. for accuracy. 

 Review the service history in your annuity estimate for accuracy. 

 Review the information about any civilian or military deposits. 

 If any data is incorrect, please inform your human resource specialist 

Consider the following to prepare for your FERCCA counseling session: 

1. Do I plan to retire from the Federal Government? FERS allows more 

flexibility for those who move in and out of Federal service. However, if you plan to stay 

with the Federal Government for your entire career, CSRS Offset will most likely provide 

you with a larger annuity benefit. 

2. When do I plan to retire? Both retirement systems have different types of 

retirements, some early retirements have an annuity reduction. 

3. How much can I contribute to the Thrift Savings Plan (TSP)? Your ability to 

contribute to TSP is a major factor in deciding which retirement plan is best for you. 

FERS has agency contributions and CSRS Offset does not. 

4. If I have not already made deposits, do I plan to make deposits for military 

and/or civilian temporary service? Payment of deposits and redeposits may determine 

if that service can be used in your annuity calculation or whether your annuity 

computation is reduced to account for the non-payment.

Offset: Election Between FERS and CSRS Offset 

G. FERCCA Counseling Fact Sheets for agency Human Resource Specialists 

Counseling someone on a FERCCA decision is very similar to ordinary retirement 

counseling. There are three areas where FERCCA counseling is very different from the 

type of retirement counseling you normally do. The areas where there are differences 

are: 

1.	 FERCCA actuarial reduction on military and civilian deposits and civilian 

redeposits 

2.	 TSP considerations 

3.	 Making the election or understanding the default election 

Otherwise you are comparing the two systems the employee is making a decision 

between. You need to emphasize the difference between the systems such as the age 

requirements for retirement, how cost of living adjustments are different between the two 

systems and other major differences.

CSRS Offset Counseling Points 

Annuity Review the comparison sheet or annuity estimates with the 

employee 

Age and service The employee needs to understand the retirement age for a 

requirements voluntary retirement is different under CSRS Offset and FERS. If 

the employee is interested in a different type of retirement make 

sure they understand the eligibility requirements for that 

retirement i.e. disability, law enforcement etc. Eligibility 

requirements are explained in Chapters 40 through 46 of the CSRS 

and FERS Handbook for Personnel and Payroll Offices. 

Unused Sick Leave Make sure the employee knows that unused sick leave can be 

Credit credited under CSRS Offset. Unused sick leave is explained in 

Chapter 20 of the CSRS and FERS Handbook for Personnel and 

Payroll Offices. 

COLAs The employee needs to understand they will receive a full COLA 

as soon as they retire under CSRS Offset. COLA’s are explained 

in Chapter 2 of the CSRS and FERS Handbook for Personnel and 

Payroll Offices. 

Survivor Benefits The employee should to know they can elect a maximum of 55% 

or any other percentage or dollar amount below 55%. Survivor 

elections are covered in Chapter 2 of the CSRS and FERS 

Handbook for Personnel and Payroll Offices. 

Military Deposit In some cases FERCCA allows for an actuarial reduction on the 

gross annuity instead of the employee paying a post 1956 military 

deposit. 

The actuarial reduction is limited to deposits for service that was 

once under FERS rules and now falls under CSRS rules, when the 

employee elects CSRS Offset. 

Deposits and Redeposits Many redeposits can be subject to actuarial reduction under the 

normal CSRS redeposit rules that are explained in Chapter 21 of 

the CSRS and FERS Handbook for Personnel and Payroll Offices. 

The FERCCA actuarial reduction is calculated in the same way 

that a CSRS redeposit actuarial reduction is calculated. 

In this case FERCCA allows for an actuarial reduction on the 

gross annuity instead of the employee paying a civilian deposit or 

redeposit.

Thrift Savings Plan 

(TSP) 

The employee is in CSRS and if they elect CSRS Offset their 

account balance will remain the same. 

Social Security If the employee chooses CSRS Offset their Social Security 

Administration (SSA) benefits may still be impacted by the WEP, but years of substantial 

earnings under Social Security reduce the impact of the WEP. If 

they have at least 30 years of substantial social security earnings 

the WEP is eliminated. The longer the employee is covered by 

Social Security as an employee the smaller the reduction from the 

WEP. The Social Security Administration has a factsheet on the 

WEP available on their website in the publications section at 

www. SSA.gov. The publication is called “Windfall Elimination 

Provision” and the publication number is 05-10045. 

The Government Pension Offset (GPO) is a Social Security 

reduction that can affect recipients of Social Security widow or 

widowers benefits. CSRS Offset retirees are not impacted by the 

GPO. For more information about the GPO see the Social 

Security publication “Government Pension Offset”. The 

publication number is 05-10007, which is available on the Social 

Security website, www.SSA.gov. 

Election All employees who are in FERS and should be in CSRS Offset 

must make a choice between CSRS Offset and FERS. They must 

make this choice using the FERCCA election form RI10-125. 

Other election forms, such as a FERS election form should not be 

used. 

Default If the employee does not make a FERCCA election within 6 

months of your providing them with the FERCCA election 

package the employee must be placed in their FERRCA default

SSA Employees who do not have a CSRS component in their FERS 

annuity are not impacted by the Windfall Elimination Provision 

(WEP). 

Employees who receive Social Security and FERS annuities with a 

CSRS component may be impacted by the WEP. This means that 

their Social Security benefits may be reduced. However, years of 

substantial earnings under Social Security reduce the impact of 

WEP. If the employee have at least 30 years of substantial Social 

Security earnings the WEP is eliminated. The employee is 

covered by Social Security the smaller the reduction from the 

WEP is. The Social Security Administration has a factsheet on the 

WEP available on their website in their publications section at 

www.SSA.gov. The publication is called “Windfall Elimination 

Provision” and the publication number is 05-10045. 

The Government Pension Offset (GPO) is a Social Security 

reduction that can affect recipients of Social Security widow or 

widowers benefits. FERS retirees are not impacted by the GPO. 

For more information about the GPO see the Social Security 

publication “Government Pension Offset” and the publication 

number is 05-10007, which is available on the Social Security 

website, www.SSA.gov.
