The Biggest Mistakes Federal Employees Make Planning for Retirement

Most of them are not investment mistakes. They are arithmetic and paperwork, and nearly all of them are fixable years in advance and difficult to fix later.

The costly federal retirement mistakes are rarely about investments. They are misreading the high-3, leaving service time uncredited, retiring under MRA plus 10 without understanding the reduction, planning from a gross annuity figure, and discovering too late that FEHB, FEGLI and the survivor election largely close behind you.

Treating six benefits as six decisions

The pattern underneath almost every mistake on this page is the same. Federal retirement is one system with six interacting parts, and it gets decided as six separate errands, usually in the last few months, often by different people on different days.

The annuity is estimated by the benefits office. The TSP is handled online. Insurance elections are forms. Social Security is a separate agency entirely. Nobody owns the question of what the combination produces as monthly income after tax, and that is the question that matters.

The map of how the pieces connect is in federal employee retirement planning. What follows is what goes wrong when they are handled in isolation.

Misreading the high-3

The basic annuity is computed from your highest three consecutive years of average basic pay, not your highest three calendar years and not your final salary. Locality pay generally counts. Overtime, bonuses and most differentials generally do not.

Two things follow. A retirement date set a few weeks either side of a pay increase can land inside or outside the window you assumed. And anyone estimating their pension from current base salary is usually working from a number that is too high.

Get the figure from your agency rather than calculating it yourself, and ask which pay periods it actually includes.

Leaving service time uncredited

Several categories of service count toward your annuity only if a deposit or redeposit is paid. Military service is the common one. Temporary or seasonal service before a career appointment can be another, and so can a period where you took a refund of contributions after leaving and later returned.

Interest accrues on these deposits after an initial period, so the cost rises the longer the decision sits. People routinely discover the option in their final year, when it is at its most expensive and there is no time to spread the payment.

Unused sick leave is the opposite case and is widely underestimated. For FERS retirees it generally adds to the service time used in the computation, which is why burning sick leave in a final year can quietly cost annuity rather than save it.

Retiring under MRA plus 10 without doing the arithmetic

Reaching your minimum retirement age with at least ten years of service lets you retire. It does not give you an unreduced annuity. The benefit is generally reduced for each year you are under 62, and that reduction is permanent.

Postponing the start of the annuity can reduce or avoid that, and crucially tends to preserve the path back to federal health and life insurance. Deferring, which is a different thing, generally does not. Those two words get used interchangeably and the consequences are not interchangeable at all. The mechanics are in how FERS retirement works.

Planning from gross instead of net

An annuity estimate is a gross figure. What arrives is smaller, and the gap surprises people in their first year.

Comes out of the gross annuityWorth knowing
Federal income tax withholdingMost of the annuity is taxable; a small portion representing your own contributions generally is not
State income tax, where applicableKansas and Missouri treat retirement income differently, which matters either side of the state line
Survivor annuity electionA reduction to your own annuity, chosen at retirement
FEHB premiumContinues in retirement, with the government share, if you are eligible to carry it
FEGLI premiumDepends on the reduction election you make, and generally rises with age

Compare net to net. Take your current take-home pay and set it against the projected annuity after all of the above, plus whatever the TSP will provide. That is the only comparison that answers whether you can afford the date.

Missing the checks that close behind you

  • FEHB. Carrying coverage into retirement generally requires enrollment for the five years immediately before you retire. The test is met on your retirement date or it is not, and waivers are rare.
  • FEGLI. The reduction election is made at retirement. Coverage can generally be reduced or cancelled later, not increased.
  • The survivor annuity. Elected once, with a short window afterward, and it determines whether your spouse can keep FEHB after your death. That link is the single most missed item in federal retirement.

All three are covered in FEHB, FEGLI and survivor elections.

TSP mistakes in the final years

Two are common and both cost money quietly. Front-loading contributions to hit the annual limit early can end your agency matching for the remaining pay periods of the year, so spreading contributions across all of them usually captures more. And becoming very conservative too early, years before any of the money will be spent, trades growth for a kind of safety the plan may not need.

A third is deciding what to do with the balance at separation without comparing the options. A rollover is one choice among several, and the comparison is in TSP rollover options.

Treating the supplement and Social Security as one decision

The FERS annuity supplement, where it applies, ends at 62 whether or not you claim Social Security then. It is also subject to an earnings test, so post-retirement work above an annual limit reduces it. People accept a second career without modelling that, and are surprised twice: once by the reduction, and again when the supplement stops regardless.

Claiming is its own decision, covered in how Social Security coordinates with a federal pension.

Starting late

Nearly everything above is cheap to fix five years out and expensive or impossible to fix five months out. The FEHB window is a five-year lookback. Deposit interest compounds. The high-3 depends on pay periods that have to actually happen. Sick leave accrues.

The single most useful thing a federal employee can do is request an annuity estimate earlier than feels necessary, and read it alongside a Social Security statement and a TSP balance rather than on its own.

Federal households in Lenexa

Lenexa sits west along the I-35 corridor, home to the Legler Barn Museum and the City Center district, with Flat Rock Creek Park marking an original campground on the westward trails. It is about twenty-five minutes from our office, and like the rest of Johnson County it has a steady federal workforce. The conversations we have there are usually corrective rather than exploratory: a retirement date already chosen, an estimate already in hand, and a set of questions nobody has yet put side by side. That is what our federal employee retirement planning is for, done alongside your agency benefits office rather than in place of it. See the communities we serve across the Kansas City area.

Common questions

What are the biggest mistakes federal employees make planning for retirement?
Estimating the pension from current salary rather than the high-3, leaving military or temporary service uncredited because a deposit was never paid, retiring under MRA plus 10 without understanding the permanent reduction, planning from a gross annuity figure instead of net, and missing that FEHB eligibility, the FEGLI election and the survivor annuity largely cannot be revisited after retirement.
What is the high-3 and why do people get it wrong?
It is the average of your highest three consecutive years of basic pay, which usually includes locality pay but generally excludes overtime, bonuses and most differentials. People get it wrong by using current base salary, which is typically higher, and by assuming it means three calendar years. Ask your agency which pay periods are actually in your figure.
Does unused sick leave count toward a FERS pension?
For FERS retirees, unused sick leave generally adds to the service time used in the annuity computation. That is why spending down sick leave in a final year can cost annuity rather than save anything. Confirm how your own balance will be credited with your agency benefits office.
Why is planning from the gross annuity a mistake?
Because the gross figure is not what arrives. Federal withholding, any state income tax, the survivor annuity reduction, the FEHB premium and the FEGLI premium all come out of it. Compare your current take-home pay against the projected annuity after those deductions plus whatever the TSP will provide. Net to net is the only comparison that answers whether the date works.
How early should a federal employee start planning?
At least five years before the intended date, because several of the most consequential items depend on a five-year lookback or on interest that compounds. FEHB eligibility, any service deposit, the pay periods that form your high-3 and your sick leave balance are all easier to influence years out than months out.
What is the difference between postponing and deferring a FERS retirement?
Both delay the start of the annuity, but the insurance consequences differ. Postponing after an MRA plus 10 retirement generally preserves the path back to FEHB and FEGLI when the annuity begins. Deferring, where you separate before your minimum retirement age and leave contributions in place, generally does not allow that coverage to be resumed. Confirm your situation with OPM.
