Your FERS refund depends on how long you worked and how much you contributed

The amount you get back from the Federal Employees Retirement System (FERS) is based on your own contributions to the system, plus interest that accrued while you were employed. The government does not refund its matching contributions — only your money comes back. If you worked for the federal government for fewer than five years, you are may have access to to a refund of your contributions plus interest. If you worked five years or longer, you have the option to take a refund or leave your money in the system to earn a pension later.

The Office of Personnel Management (OPM) calculates your exact refund amount using your Basic Pay Records, which show every paycheck deduction you made into FERS. The calculation includes your contributions from each pay period, plus interest compounded annually at a rate set by law — currently 0.5% per year, though this rate can change. OPM does the math; you do not have to.

Key Takeaways

  • Your FERS refund is your own contributions plus interest, never the government's matching money.
  • OPM calculates the exact amount based on your pay records and sends you a statement before you decide whether to take the refund or keep the money in the system.
  • The interest rate on FERS refunds is set by federal law and is currently 0.5% annually, compounded each year you were employed.
  • If you worked fewer than five years, you must take a refund; if you worked five years or more, you can choose a refund or a future pension.

How OPM calculates the refund amount

OPM pulls your Basic Pay Records from your agency's payroll system. These records show the exact dollar amount deducted from your paychecks for FERS contributions during each pay period you worked. The agency then adds interest on top of that total.

The interest calculation works like this: OPM takes your contributions from each year, applies the annual interest rate (0.5% as of now), and compounds it forward to the date you separate from federal service. A contribution made in year one earns interest for every year you remained employed; a contribution made in your final year earns interest only for that year. The longer you worked, the more interest accumulates on your earlier contributions.

You do not need to request this calculation or provide documents. OPM has your pay records already. When you separate from federal employment, OPM generates a Statement of Benefits that shows your total contributions, the interest amount, and the combined refund total. This statement arrives in the mail or through your OPM account, depending on how your agency processes separations.

What the Statement of Benefits tells you

The Statement of Benefits is a one-page document that breaks down three numbers: your total contributions (the sum of all deductions from your paychecks), the interest earned, and the refund amount (contributions plus interest). It also tells you the date of your separation and whether you are may have access to to a refund or have the option to choose between a refund and a pension.

Read the contribution total carefully. If you see a number that seems too low or too high, it may mean a pay period was missed, a leave-without-pay period reduced your contributions, or you had a break in service. If the number does not match what you expect, contact your agency's human resources office or OPM's retirement services line before you decide what to do with the refund.

The statement also shows the interest calculation. The interest rate is fixed by law and does not vary based on how the economy performs. You cannot negotiate it or ask for more. The rate applies to all federal employees uniformly.

Factors that change your refund amount

Several things can reduce the refund you receive. If you took a leave-without-pay period during your federal career, your contributions for those months are lower, which means less interest accrues. If you had a break in service — a gap between two periods of federal employment — interest stops accruing during the gap and restarts when you return.

If you owe money to the federal government, OPM may offset your refund. Common offsets include unpaid taxes, student loans in default, or child support arrears. OPM will notify you in writing if an offset applies before your refund is processed. You have the right to request a hearing to dispute the offset, though the process takes time.

Survivor Benefit Plan (SBP) elections can also affect your refund. If you elected SBP coverage during your employment, a portion of your refund may be withheld to pay the SBP deposit. This is separate from your regular contributions and interest.

When you receive the refund amount in writing

OPM mails the Statement of Benefits within 30 days of your separation date, though this timeline varies depending on how quickly your agency submits your separation paperwork. If you separated on a Friday, OPM may not receive the paperwork until the following week, which delays the clock.

Once you receive the statement, you have 30 days to decide whether to take the refund (if you worked fewer than five years) or choose between a refund and a pension (if you worked five years or longer). You do not have to decide immediately, but the 30-day window is firm. If you do not respond, OPM will send a reminder, and if you still do not respond after the reminder, your money stays in the FERS system and you will receive a pension at retirement age instead.

If you do not receive the statement within 45 days of separation, contact OPM's Retirement Services at 1-888-767-6738. Have your name, date of birth, and agency name ready.

How to request a detailed breakdown if the amount seems wrong

If the refund amount on your Statement of Benefits does not match what you calculated yourself, you can request a detailed accounting from OPM. Call the Retirement Services line and ask for a Detailed Contribution History. OPM will mail you a document that lists every pay period, the contribution amount for that period, and the interest applied to that contribution.

Common reasons the refund is lower than expected: you had unpaid leave periods, you took a break in service, you were on leave-without-pay status, or you had a period of part-time employment. Common reasons it is higher: you worked longer than you remembered, or interest compounded over many years added more than you anticipated.

If you find an error in the contribution history — a missing pay period, a wrong amount, or a period you do not remember — report it to your agency's human resources office first. They can check the original payroll records. If HR confirms an error, they will notify OPM, and OPM will recalculate your refund.

Taxes on your FERS refund

Your FERS refund is subject to federal income tax. OPM will withhold 20% of the refund amount for taxes unless you instruct them otherwise. You can choose a different withholding rate or request no withholding, but the IRS will still expect you to pay taxes on the full amount when you file your return.

If you roll the refund into an Individual Retirement Account (IRA) or another may have access to retirement plan within 60 days, you can defer the taxes. This is called a rollover. If you take the money as a direct payment instead, the 20% withholding is immediate and you owe the rest at tax time.

Consult a tax professional before you decide how to handle the refund. The tax treatment depends on your overall income, your filing status, and whether you have other retirement accounts.

Frequently Asked Questions

Does my FERS refund include the government's matching contributions?

No. Your refund is only your own contributions plus interest. The government's matching contributions stay in the FERS trust fund and are not returned to you. If you worked five years or longer, you can leave your contributions in the system to earn a pension, which does include credit for the government's matching money.

What if I worked for the federal government in two separate jobs?

If both jobs were covered by FERS and you had no break in service between them, they count as one continuous period. Your refund includes contributions from both jobs. If there was a break in service, the periods are separate and interest stops during the gap.

Can I change my mind after I take the refund?

No. Once OPM processes your refund payment, the decision is final. You cannot put the money back into FERS or change it to a pension. If you are unsure, do not cash the check immediately — contact OPM's Retirement Services to discuss your options before you accept the payment.

How long does it take to receive the actual refund check after I decide to take it?

OPM typically processes the refund within 30 days of receiving your written request to take the refund. The check is mailed to your address on file. If you set up direct deposit, the funds go to your bank account instead, which is faster. Contact OPM if you do not receive the payment within 45 days of your request.

What happens to my FERS refund if I die before I receive it?

If you die after separating but before OPM processes your refund, the refund goes to your estate or to the beneficiary you named on your FERS form. Your family should contact OPM with a copy of the death certificate to claim the refund.
