Your first year of retirement: cash flow and taxes

Because it contains your old life and your new one. For part of the year you were a federal employee drawing a salary. For the rest you are a retiree drawing an annuity. Your tax return has to hold both, plus a lump-sum leave payment that belongs to neither.

No later year looks like this. Once you are into your first full year of retirement, your income settles into a steadier and usually much smaller set of sources. That is the year worth budgeting from.

The mismatch causes two predictable problems. People set their tax withholding for retirement income while the year still contains salary, and people build a monthly budget from a year that included several months of full pay. Both errors point the same direction: the first year flatters you.

This lesson covers the shape of that year and what to do about it. It does not re-explain how each income type is taxed, which the FERS income tax lesson covers in full.

Four things, and only one of them continues afterward. You receive salary for the part of the year you worked, a lump-sum payment for unused annual leave, annuity payments from your retirement date onward, and the Special Retirement Supplement (SRS) if you qualify for it.

Take Dana, a hypothetical federal retiree who separates at the end of June. Dana draws six months of salary, receives a leave payout worth several weeks of pay, and collects six months of annuity and supplement. The figures below are illustrative only; see our assumptions for the values the calculator uses.

The shape is the point, not the amounts. Dana’s separation year total sits well above what a full year of retirement will pay, because two of the four sources stop permanently and a third only ever covered half the year.

The lump sum deserves particular attention. It arrives as wages, taxed as ordinary income in the year received, and it can equal a meaningful share of the year’s total. The leave payout lesson covers how it is calculated and withheld.

Uneven, and in a specific order. Your salary stops on a known date. Your annuity starts at a partial rate. Your leave payment can be months away. Those three facts rarely line up neatly.

The annuity is the part that surprises people. OPM does not pay your full amount immediately. It places you into interim pay, a partial monthly estimate, while it finishes reviewing your case, then issues an adjustment once the case is finalized. The OPM processing lesson covers the amounts and the timeline.

The lump-sum leave payment is the slowest piece. OPM guidance is explicit that it can take several months, because your agency has to complete offboarding and audit your leave account first. The final paycheck lesson covers the full payment sequence.

So the low point is early and temporary. In the first months you may be living on a partial annuity, with the leave payment and the adjustment payment both still ahead of you. Planning around that trough is more useful than planning around the year’s total.

Because you set it for a retirement income that the year does not actually contain. When you elect withholding on your annuity, you are choosing a rate for annuity income. The calendar year it applies to still holds months of salary and a lump-sum payment.

Each piece is also withheld by a different payer using different rules. Your agency withholds from your salary. Your agency withholds from the leave payout separately, often at the flat supplemental-wage rate rather than your usual paycheck rate. OPM withholds from your annuity based on the election you give it. None of the three coordinates with the others.

That is how retirees end up either owing at filing or over-withholding badly. The mechanics of setting and changing withholding, and when quarterly estimated payments make sense, are covered in the FERS income tax lesson.

The year-one action is simply to revisit it. An election set once at retirement and left alone is being applied to two very different years in a row. Checking the total partway through the year is cheaper than discovering the gap at filing.

Your income becomes representative, and usually a good deal smaller. The salary is gone, the leave payment was a one-time event, and your annuity is being paid at its finalized rate for all twelve months rather than part of them.

Two things arrive that your separation year did not have. Your annuity is finalized, so the interim estimate and the adjustment are behind you. And you become eligible for a cost-of-living adjustment, though your first one is partial and FERS adjustments generally do not begin before age 62. The COLA lesson covers both the proration and the age gate.

The comparison below is what most people should be budgeting from. If a retirement plan works in the first full year, it is working against real numbers. If it only works in the separation year, it was never tested.

This is also when the tax picture stabilises. One income shape, one set of payers, and a withholding election you can now match to reality.

Treat the separation year as a one-off and plan two things separately: the cash trough at the start, and the tax bill at the end. They are different problems with different timing.

For the trough, hold cash. The gap between your last salary and your finalized annuity is measured in months, and the leave payment that would cover it is the slowest of the three payments. Cash on hand is what turns that from a problem into an inconvenience.

For the tax bill, check your total partway through the year rather than at filing. You are the only party who can see salary, leave payout, and annuity together, because no single payer does.

Then rebuild the budget once your annuity is finalized. That is the first honest number you have. To see whether the whole plan holds up against it, run your free readiness score.
