Retiring from the military under the Blended Retirement System gives you a choice most retirees never see: take part of your pension as a lump sum now, and get a smaller monthly check for years afterward. That trade-off deserves a close look before you sign it.
24/7 Wall St. recently profiled a veteran who took the lump sum and watched his monthly retired pay stay reduced by the percentage he chose, 25% or 50%, until he reached 67, the age Social Security calls full retirement age. His military pension and Social Security are two separate systems, but the date one uses to restore his pay is borrowed directly from the other.
Decision
Where are you in this decision?
The right next step depends on whether you've already elected a lump sum or are still weighing it.
What the Lump Sum Actually Changes
The Blended Retirement System lets you trade 25% or 50% of your monthly retired pay for an upfront lump sum. In exchange, your monthly check drops by that same percentage, not for a year or two, but until you reach 67. Retire in your 40s and take the 50% option, and you could spend two decades on reduced pay before it restores.
Full military retired pay comes back at 67 automatically. That doesn't mean you have to start Social Security the same year. Social Security can still start as early as 62 or as late as 70, and delaying it past 67 keeps growing your eventual benefit, so the two dates are worth planning separately.
Military retired pay and Social Security don't reduce each other. You keep both benefits in full no matter which one you claim first, and that has been true for military retirees all along, unlike some civil-service pensions before a 2025 law ended two offset rules that used to apply to them. Read Tricare and Medicare Enrollment at 65 for the other big deadline that lands around the same age.
Keep a Record While You Wait for the Restore Date
Years of reduced pay is a long time to rely on memory. Keep a written record of every call to DFAS, every date you're given, and every answer about how the reduction interacts with survivor benefits or disability pay.
This record also matters if the restore date on a pay statement ever looks wrong. A specific date and the name of who confirmed it turns a dispute into a quick correction instead of a drawn-out appeal.
Keep proof of every benefits call and promised next step.

Work through the restore date in order
Check off each step as you complete it.
Get it in writing or note the confirmation number.
Compare starting at 62, 67, or 70 against your own health and income needs.
Match it against the date DFAS confirmed and flag any mismatch immediately.
Save what you decided here so you can follow through on the restore date.
Plan the Two Dates Separately
Treat the year your full military pay restores and the year you start Social Security as two different decisions, not one automatic switch. Waiting on Social Security past 67 keeps growing that benefit up to age 70, regardless of what your pension is doing.
If you're still working in any capacity when your pension restores, that income can also affect how much of your Social Security benefit is taxable, which is one more reason to look at both numbers together rather than assuming the restore date settles everything.

Common questions
How long does a military pension lump sum reduce my monthly retired pay?
Under the Blended Retirement System, choosing a 25% or 50% lump sum reduces your monthly retired pay by that same percentage until you reach 67, the age Social Security calls full retirement age. Retire in your 40s and the reduction can last two decades.
Do I have to start Social Security when my military pension restores at 67?
No. Your full military retired pay restores automatically at 67, but Social Security is a separate decision. You can start it as early as 62 or delay it as late as 70, and delaying past 67 keeps increasing the eventual benefit.
Does a military pension reduce my Social Security benefit?
No. Military retired pay and Social Security don't offset each other, and you can receive both in full no matter which one you claim first. A 2025 law also ended two offset rules, the Windfall Elimination Provision and Government Pension Offset, that used to reduce Social Security for some people with government pensions.
