Milestone Ages

By Steven Puckett

Planning for retirement as a federal employee means navigating a unique set of rules, benefits, and critical ages. As someone who has worked with federal employees for years, I’ve found that understanding the milestone ages in the Federal Employees Retirement System (FERS) can dramatically impact your long-term outcomes. These aren’t just arbitrary numbers. Each age unlocks specific options, rights, and responsibilities that shape your retirement readiness.

Let’s walk through these milestones to better understand what each one means and how it may affect your federal retirement journey.

Under Age 50: The Foundation Years

When you’re under 50, it may seem like retirement is a lifetime away. But this is when foundational habits take root. Your focus should be on:

Understanding the TSP (Thrift Savings Plan): Knowing your fund options (G, F, C, S, I) and learning how to allocate based on time horizon and risk tolerance.
Contributing Consistently: At a minimum, contribute enough to get the full agency match of 5%. At the time of this article the contribution limit for the TSP is $23,500.
Tracking Service Time: Especially important if you had military service or prior federal time that can be bought back.

These early years are when compounding works its magic. Small increases in your contributions now can mean thousands more later.

Age 50: Catch-Up Contributions Begin

At age 50, the IRS allows you to contribute more to your TSP through catch-up contributions. This is a great opportunity to make up for any lower savings years earlier in your career.

If you’re behind on savings, this is the time to take it seriously. And even if you’re on track, adding more into the TSP in your peak earning years builds flexibility later. The current catch-up contribution amount at the time of this article is $7,500.

Age 55: Separation Without Penalty (For Some)

This is a big one. If you separate from service in the calendar year you turn 55 or later, you can withdraw from your TSP without the 10% tax penalty (you could still have income taxes).

This applies only to the TSP and only if you separate the year you are turning 55 or later. It doesn’t apply to IRAs. This distinction is critical for anyone planning to retire before 59.5.

Age 56–57: Minimum Retirement Age (MRA)

Your MRA depends on your birth year, and for most employees today, it falls between 56 and 57. Once you hit your MRA, a few retirement options come into play:

Immediate/Unreduced Retirement: If you have at least 30 years of creditable service.
MRA + 10: Retire with at least 10 years of service and at your minimum retirement age, but incur a reduction to your pension but no lapse in health benefits.
Postponed Retirement Options: Available if you leave federal service at your MRA with at least 10 years of service but want to claim benefits later and avoid a reduction to your pension. Note that your FEHB (Federal Health Benefits) would be postponed until your pension starts.

Understanding MRA rules helps you determine your earliest realistic exit point and how much that may cost you in reduced benefits.

Age 59 ½: IRA and TSP Flexibility Increases

This is the age when you can access your traditional IRAs without the 10% penalty and your TSP while you are still working. If you retired before 59 ½ and didn’t qualify under the age 55 rule, this is your next major chance to access retirement money without the penalty as well.

This age is also when Roth IRAs (opened at least 5 years ago) become fully tax-free if you’re withdrawing from them.

Age 60-63: “Super Catch-Up”

Anyone turning 60, 61, 62, or 63 in 2025 are eligible for a larger catch-up contribution of $11,250 making a total contribution limit of $34,750.

Age 62: Enhanced Pension Formula/Social Security Eligible/Supplement Ends

For FERS employees, the formula used to calculate your pension improves at age 62 if you have at least 20 years of service:

Under age 62 or under 20 years: 1% of high-3 salary x years of service
At age 62 with 20+ years: 1.1% of high-3 salary x years of service

This extra 0.1% may sound small, but over a lifetime, it adds up. For some, this may be the reason to delay retirement until 62.

Age 62 is also the earliest you can start taking your social security (not including social security disability). It is not always a good idea to start your benefits right away, however, and you should consider income needs, spousal income, longevity, etc.

For those receiving the supplement, it will end as soon as you reach age 62.

Age 65: Medicare Eligibility

Age 65 is the starting point for Medicare Part A and B. If you’re still working, you may defer Part B enrollment without penalty, but can still enroll in Part A.

For retirees, this is a decision point: Do you keep FEHB (Federal Employee Health Benefits), enroll in Medicare, or combine them?

Many choose to keep FEHB and add Medicare Part A, sometimes opting out of Part B due to premiums. The right move depends on your health, income, and expected medical costs.

Age 73: Required Minimum Distributions (RMDs)

This is a major trigger point. At age 73, the IRS requires you to begin taking minimum distributions from your traditional TSP and IRAs. Roth IRAs and TSPs are excluded.

Even if you don’t need the money, you’ll need to start drawing down your account to avoid penalties. Planning ahead can reduce tax burdens by shifting money earlier, converting to Roth, or blending with other income sources. You do not have to take RMDs out of your TSP if you are still working but would still need to take them out of IRA’s.

Required Minimum Distribution age looks like it will be pushed back to age 75 in year 2035.

In Summary

Each of these milestone ages represents more than just a birthday. It’s a point where the rules change, and your options expand or contract. Understanding these ages and planning around them gives you the control to shape your retirement income, benefits, and flexibility.

As a federal employee, your retirement path is governed by unique rules. The earlier and more intentionally you prepare, the more confident you’ll feel when it’s time to retire—or even just make the next move.
