The cleanest answer to an MRA+10 reduction is the postponement option: separate from federal service at your MRA, decline to commence the annuity immediately, and let the deferred annuity grow with your age until the reduction disappears. The tool exists. It is also less straightforward than it sounds, and the consequences for FEHB and FEGLI during the postponement period are where most of the planning errors get made.

Here is how the postponement actually works.

The mechanics of postponement.

When you separate from federal service at or after your MRA with at least 10 years of creditable FERS service, you have an election to make:

  • Commence the annuity immediately. The MRA+10 reduction applies, calculated against your age at the date the annuity begins.
  • Postpone the commencement. You separate, you do not draw an annuity, and the reduction calculation is based on your age at the future date you choose to begin receiving the annuity.

The annuity is calculated at the postponed commencement date using your actual age at that date and your total years of creditable service at the time of separation. The reduction shrinks toward zero as your age at commencement approaches 62.

Most employees who postpone elect to begin the annuity at age 62, which is the earliest age at which the MRA+10 reduction disappears entirely. Some elect to begin earlier than 62 if the reduction remaining is acceptable and they need the income. Some elect to wait past 62 to capture additional sick-leave credit conversions, additional TSP growth, or simply to keep working elsewhere.

What happens to your high-3 and your service.

The annuity calculation at the postponed commencement date uses your high-3 average salary at the time of separation, not at the time of commencement. Your years of creditable service are also frozen at the separation date, with the exception of unused sick leave (which is added at the time of retirement processing).

This has a counterintuitive consequence: postponement does not give you a higher annuity through additional high-3 salary growth. The high-3 is fixed at separation. The postponement gets you out of the reduction, but it does not get you a bigger annuity through additional service.

How long can you postpone?

You can postpone the commencement of an MRA+10 annuity to any date between your MRA and age 62, when the reduction disappears. There is no requirement to begin the annuity at 62; you can choose any later date as well, though the annuity calculation will not benefit from additional service credit beyond the original separation date.

In practice, most employees who postpone do so to exactly age 62, for two reasons. First, that’s the earliest date the reduction disappears entirely. Second, age 62 also unlocks the 1.1% enhanced multiplier if you have at least 20 years of service at the time of original separation. If you have fewer than 20 years of service at separation, the 1.1% multiplier is not available regardless of when you commence the annuity.

The trade-offs you have to plan for.

Postponement is not free. During the postponement period:

  • You are no longer a federal employee. You cannot contribute to the TSP. You do not receive the agency match. Your TSP balance continues to grow from market returns only.
  • You are not eligible for FEHB coverage as an employee. Continued FEHB coverage into retirement requires that you have FEHB continuously for the five years immediately preceding retirement. If you postpone the annuity, the five-year clock is still running against your separation date, not your commencement date.
  • FEGLI coverage also depends on continuous enrollment rules, and the conversion options change after separation. Postponement limits some of those conversion pathways.
  • You will be earning income from somewhere else during the postponement. That income may push you into higher tax brackets or trigger IRMAA surcharges two years later on Medicare premiums, depending on your age.

Postponement is a legitimate, often smart tool. It is not a free lunch. The coverage consequences are where most postponement decisions need the most careful modeling.
