Phased retirement

1. How it works

Congress created phased retirement in the Moving Ahead for Progress in the 21st Century Act; OPM's implementing rules took effect in August 2014. The idea is simple: instead of the cliff edge where a career ends on a Friday and retirement begins on a Monday, an eligible employee moves to half-time and starts collecting part of the pension early.

Mechanically:

• You work a 50% schedule — 40 hours per pay period — and your gross pay is halved.
• OPM computes the annuity you would have received had you fully retired on that date, without sick leave credit and without a survivor election, then pays you half of it each month.
• You remain an employee for every other purpose. Health and life insurance, TSP, leave accrual, and pay all continue under employee rules, not annuitant rules.
• Twenty percent of your working time goes to mentoring other employees. That is the trade Congress asked for in exchange for the arrangement; Postal Service employees are exempt.
• When you fully retire, OPM recomputes everything into a single composite annuity. Section 5.

2. Who is eligible

Excluded outright: part-time employees, and special-category employees — law enforcement officers, firefighters, air traffic controllers, and nuclear materials couriers. Anyone relying on an MRA+10 reduced annuity is also out, because the statute requires eligibility for an immediate unreduced retirement.

The three-year full-time requirement catches people by surprise. If you dropped to part-time two years ago to ease toward retirement, you have disqualified yourself from the program designed for exactly that purpose.

3. The 20% mentoring rule

Phased retirement comes with a duty attached. With the exception of Postal Service employees, at least 20% of your working hours must go to mentoring activities. The point is knowledge transfer — passing your experience to the people stepping into senior roles as you step back.

Your agency decides what counts as mentoring and how it is tracked, and you can mentor one employee or several, rotating among them over time. Agencies may waive the requirement only in an emergency or other unusual circumstance, and waivers are meant to be rare.

At 40 hours a pay period, 20% is 8 hours — one day. In practice most phased retirees describe it as the part of the job that feels most worthwhile at the end of a career, rather than a burden. But it is a formal obligation, not an aspiration, so ask how your agency documents it before you enter.

4. What you keep, what you lose

The FEHB line is the one that makes the arrangement unusual. A part-time employee normally gets a prorated government contribution. A phased retiree does not: the government keeps paying the full-time share. On a family plan that is several thousand dollars a year you would lose under ordinary part-time work.

5. A worked example

A GS-14 at 60 with 22 years, high-3 of $140,000, full-time salary $145,000.

Annuity figures use 1.1% × 22 years × $140,000, the multiplier available at 62 or later with 20 years; at 60 the multiplier is 1.0% and the numbers scale down accordingly. The shape of the comparison is what matters: half the hours for roughly 60% of the income, with benefits intact and the pension clock still running.

6. The composite annuity at full retirement

When you finally retire outright, OPM does not simply continue the half annuity. It computes a composite retirement annuity with two parts: the phased annuity you were already receiving, plus a second component covering your phased service, calculated as though that service had been full-time and using your high-3 at full retirement.

Three consequences worth knowing:

• Sick leave is credited at full retirement, not when you entered phased status, so nothing is lost by phasing first.
• Your survivor election is made at full retirement, and the composite annuity is reduced for it then.
• Phased service counts, at the part-time rate for the proration factor but computed on full-time salary, which is why the final annuity generally exceeds what you would have had by retiring outright on the phasing date.

7. The supplement problem

This is the real cost, and it is the reason phased retirement suits some people and not others.

The FERS Special Retirement Supplement is not payable during phased retirement. For someone retiring at their minimum retirement age with 30 years, the supplement can be $1,200 to $1,800 a month — $15,000 to $22,000 a year — from MRA until 62. Phase instead of retiring and you forgo all of it for the phased years.

Set against that, you are earning half a salary, which is usually more than the supplement would have been. So the arithmetic favors phasing on cash flow. The loss is real only if you would otherwise have stopped working entirely.

8. Why almost nobody uses it

Twelve years after the rules took effect, phased retirement remains one of the least-used benefits in the federal government. Three reasons, in order of weight:

Agencies have to opt in, and most have not. The statute makes phased retirement discretionary. An agency can decline to implement it at all, and many never issued the internal policy needed to process a request. If yours has not, there is nothing to apply for.

It requires a supervisor to agree. Even where a policy exists, entry must be mutually agreeable. A manager who needs a full-time body in the role can simply say no.

Awareness is low. It is not in most pre-retirement briefings, and the three-year full-time requirement quietly disqualifies people who have already downshifted.

The practical implication: ask your HR office in writing whether your agency has a phased retirement policy before you build any plan around it. That one question resolves the matter faster than any amount of research.

9. Is it right for you?

Consider it if: you want to keep working but not at full intensity; you are at 60 with 20 years so the supplement is not in play; you want more years of TSP contributions and matching; you have a large sick leave balance you would rather see credited later at a higher high-3; or you want to test retirement before committing to it.

Skip it if: your agency has no policy; you are at MRA with 30 and want to stop working, in which case the supplement plus a full annuity is the cleaner comparison; you are a special-category employee and therefore ineligible; you have been part-time within the last three years; or your plan depends on post-employment TSP withdrawals, which phased retirees cannot take.

If phased retirement is unavailable, the nearest alternatives are a postponed annuity, ordinary part-time work after full retirement subject to the three earnings tests, or reemployment as an annuitant — each with its own offsets.
