You’ve spent decades climbing the ladder. You’ve navigated the complexities of the VA, managed high-stakes projects at the DOD, or helped keep the wheels turning at the SSA. Now that you’ve reached the GS-13, 14, or 15 level, you’re at the top of your game: but you might also be reaching the end of your rope.
The thought of another 40-hour (or 50-hour) work week feels heavy. Yet, the idea of walking away entirely feels… early. Maybe you’re not ready to trade your morning commute for a permanent seat on the porch just yet.
This is exactly why Phased Retirement was created. It’s designed for the federal employee who wants to “test drive” retirement without giving up their entire paycheck or their career legacy. But for high-grade feds, there are specific financial traps you need to avoid.
Before you make any big moves, it’s worth booking a federal benefits review to see how the numbers actually stack up for your specific situation.
What Exactly is Phased Retirement? (The 50/50 Split)
Think of Phased Retirement as the “Middle Ground.” Instead of a hard stop on a Friday afternoon, you transition into a part-time role.
In the eyes of OPM, this usually looks like a 50% work schedule. You work half of your normal hours, and in return, you get:
- 50% of your regular GS salary (including locality pay).
- 50% of your earned FERS annuity (the pension you’ve built up to that point).
It’s a unique way to keep a significant portion of your income while getting 20 hours of your life back every week. You stay on the agency’s books as an employee, you keep your health insurance (FEHB) at the employee rate, and you continue to build service credit.

The “Pension Trap” Fear: Will My High-3 Suffer?
The number one question we get from GS-13s and above is: “If I go part-time, will it tank my High-3 average and ruin my final pension?”
It’s a valid fear. Most people know that your pension is based on your highest three consecutive years of salary. They worry that if they spend their last two years working half-time, OPM will use that “half-salary” in the calculation.
Here is the good news: OPM calculates your High-3 based on your annual pay rate, not your actual take-home earnings as a part-timer.
If you are a GS-13, Step 10, your High-3 is calculated using the full-time salary for that grade and step. Even if you are only working 20 hours a week, the rate stays the same. In fact, if you get a COLA increase or a step increase while in phased retirement, your High-3 can actually increase, boosting your final pension when you eventually fully retire.
However, navigating these calculations can be tricky, and OPM isn’t always the fastest at correcting mistakes. To make sure your paperwork is bulletproof, schedule a consultation with us today.
The Mentoring Requirement: Giving Back
Phased Retirement isn’t just a “thank you” for your service; it’s a strategy for the government to prevent “brain drain.” When a GS-15 retires from the DOD, they take decades of institutional knowledge with them.
To prevent this, OPM requires phased retirees to spend at least 20% of their working hours mentoring others.
If you’re working a 20-hour week, that means 4 hours are dedicated to:
- Training your replacement.
- Documenting complex processes.
- Sharing the “unwritten rules” of the agency with junior staff.
For many senior feds, this is actually the most rewarding part. You get to be the expert without the administrative headaches of full-time management.
Are You Eligible?
Not everyone can jump into phased retirement. It’s a “mutual consent” program, meaning your agency has to agree to it. They don’t have to let you do it, but many agencies like the VA and SSA are becoming more open to it to manage their aging workforce.
The basic FERS requirements are:
- Age 60 with 20 years of service, OR
- Minimum Retirement Age (MRA) with 30 years of service.
- You must have been full-time for the 3 years immediately preceding phased retirement.
If you meet these marks, you’re in the running. If you’re unsure where you stand, you can check your eligibility and numbers here.

The Trade-Offs: What You Lose
While phased retirement sounds like a dream, there are a couple of “catches” you need to be aware of:
- No FERS Special Retirement Supplement: If you retire at MRA with 30 years, you normally get the “Social Security bridge” (the Supplement). You do not get this during phased retirement. You only get it once you fully retire, and even then, only if you haven’t hit age 62 yet.
- No Lump-Sum Annual Leave: Normally, when you retire, you get a big check for your unused annual leave. In phased retirement, your leave carries over. You don’t get that payout until you fully stop working.
- The “Composite” Calculation: When you finally walk away for good, OPM does a “composite” calculation. They take your initial phased annuity and add a second piece based on the extra time you worked part-time. It’s a bit of math gymnastics that you’ll want an expert to review.
Why GS-13s and Above Should Consider This Now
As a higher-grade employee, your “cost of waiting” is high. If you are burnt out but keep pushing through at 40+ hours a week, you’re sacrificing your health and family time.
Phased retirement allows you to:
- Keep your FEHB: You stay on the employee rate, which is often better than the retiree experience during the transition.
- Maximize your TSP: You can still contribute to your TSP from your 50% salary, potentially snagging another couple of years of agency matching.
- Soft Landing: You get to see what life feels like with 3-day weekends every single week.

Final Thoughts
Phased retirement is a powerful tool, but it’s not a “set it and forget it” decision. Because it involves a complex mix of part-time pay and partial annuity payments, a single paperwork error can lead to months of headaches with OPM.
Don’t leave your “High-3” to chance. Whether you’re at the VA, DOD, or SSA, you’ve earned the right to a smooth transition.
