Should I Take a Refund of FERS Contributions

The Question Everyone Asks at the Exit Briefing

You're leaving federal service. HR hands you SF 3106 and explains that you can cash out your FERS retirement contributions. The dollar figure looks tangible — money in your pocket within a few months. The alternative — a pension check that won't start for 15 or 20 years — feels abstract. That asymmetry leads a lot of people to take the refund without running the numbers.

What the Refund Actually Gives You

Your SF 3106 refund returns the employee contributions you paid into the Civil Service Retirement and Disability Fund — roughly 0.8% of your salary per year for original FERS employees, 3.1% for FERS-RAE (hired in 2013), or 4.4% for FERS-FRAE (hired 2014 or later). If you had more than one year of service, the refund includes compound interest at variable Treasury rates.

The principal is non-taxable (you paid it with after-tax dollars). The interest is taxable income. For refunds of $200 or more, OPM withholds 20% from taxable interest paid directly to you, and you may owe a 10% early distribution penalty if you're under 59½. Rolling eligible taxable interest directly into a traditional IRA, eligible employer plan, or your TSP avoids withholding on the rolled amount and generally defers income tax until you withdraw it.

What the Refund Costs You

Taking the refund removes that service from the amount calculation for your FERS annuity and any survivor annuity. If you were covered by FERS on or after October 28, 2009, refunded service still counts toward retirement and survivor-benefit eligibility, but not toward those benefit amounts unless a full redeposit with interest is paid. If you were not covered by FERS on or after that date, the refund permanently forfeits retirement rights based on that service.

The Break-Even Math

Consider a GS-12 Step 5 employee leaving after 10 years with a High-3 average salary of $82,000 (original FERS, 0.8% contribution rate). Their refund would be approximately $6,560 in principal plus interest.

Their deferred annuity at age 62: 1.0% × $82,000 × 10 years = $8,200 per year, or about $683 per month for life. At that rate, the pension recoups the refund amount in under 10 months. After that, every month is pure gain.

Even accounting for inflation erosion on the frozen High-3 (at 2.5% annual inflation, that $8,200 annuity buys roughly $4,700 in today's dollars 22 years from now), the lifetime present value of a guaranteed pension typically exceeds what most people achieve by investing the refund privately.

The refund wins in a narrow set of circumstances: you have very few years of service (5-6), your contribution balance is relatively large (FERS-FRAE at 4.4%), you have high-confidence private investment returns, and you are certain you'll never return to federal service.

When Keeping Your Money In Makes More Sense

• You have 10+ years of service — the annuity multiplier makes the pension proportionally more valuable
• You might return to federal service — redeposit interest compounds for years and can double the original refund cost
• You want spousal survivor protection — the deferred annuity preserves survivor benefit eligibility
• You'd rather have guaranteed income — the pension pays for life regardless of market performance

FERS-RAE and FERS-FRAE Employees: A Different Calculation

If you were hired in 2013 or later, your contribution rate is 3.1% or 4.4% instead of 0.8%. That means your contribution principal is about 3.9 or 5.5 times larger, respectively, for the same salary and service. The break-even period stretches, and the case for investing privately gets stronger — though the pension still wins over a 20+ year retirement horizon in most scenarios.

The Tax Move Most People Miss

If you do take the refund, rolling eligible taxable interest directly into a traditional IRA, eligible employer plan, or TSP can defer tax. For refunds of $200 or more, direct payment results in 20% withholding on the taxable interest, and may also trigger a 10% penalty; you'll owe any remaining tax when you file. A direct rollover defers tax until you withdraw the funds, when you may be in a lower bracket.
