Turning 66 in 2026? Your Full Retirement Age Is Actually 67

For decades, 66 was the number attached to full retirement age. It showed up in retirement calculators, in the coverage your parents talked about at their own retirement, in financial-planning worksheets, and in the mental math a lot of people still use when they think about filing for Social Security. If you were born in 1960, that number no longer applies to you. Your full retirement age is 67, a full year later than the age most people still expect, and treating 66 as your number can lead you to file too early without realizing it. That single year makes a real difference in what your monthly check looks like if you claim ahead of it.

Nothing changed this year in Congress, and this is not a new law. It's the last step of a schedule set back in 1983, when lawmakers raised full retirement age gradually over three decades so the shift would never land on anyone all at once. The schedule has been sitting in the law this whole time, moving quietly through birth year after birth year, and 2026 is simply the year it reaches the group turning 66. People born in 1960 turn 66 in 2026, which makes this the first year the gap between the number in your head and your actual full retirement age becomes real for a whole group of retirees at once. If you were born a few years earlier, your own number moved too, just by a smaller amount. Below, see your real number and what it changes about when you claim.

What changes if you claim before your full retirement age

Claiming before your full retirement age lowers your monthly benefit for the rest of your life. The reduction is calculated month by month between the age you file and your actual full retirement age, not the age of 66 that might still be in your head. The earlier you file relative to that real number, the deeper the cut, and the cut is permanent once you start collecting, even if your income situation changes later. Someone who planned around a full retirement age of 66 and files at what they thought was full retirement age, but is actually still a year early under the real schedule, ends up with a smaller check than they expected for the rest of their life.

That's why the shift to 67 matters beyond the label. Someone with a full retirement age of 66 who claims at 62 gives up about 25 percent of their benefit. Someone with a full retirement age of 67 who claims at that same age, 62, gives up closer to 30 percent, because there are more months of reduction between 62 and 67 than there are between 62 and 66. If your full retirement age falls between 66 and 67, because you were born from 1955 to 1959, your reduction at 62 lands somewhere in between those two figures, tied to the exact month your full retirement age adds up to. Waiting past your full retirement age still adds delayed retirement credits up to age 70 either way, worth roughly 8 percent a year, so that part of the decision doesn't change based on which full retirement age applies to you.

Where to see your own number

The most reliable place to check your full retirement age is your Social Security statement, either the paper version mailed periodically or the version inside your online account. It lists your exact full retirement age next to your benefit estimate at that age, tied to your actual date of birth rather than a general chart. If you were born in 1960 or later, look for 67 years and 0 months. If you were born between 1955 and 1959, look for an age between 66 years 2 months and 66 years 10 months, since it rises two months for every birth year in that stretch, not a flat jump straight from 66 to 67. Full retirement age is also a different number than Medicare eligibility, which stays at 65 no matter your birth year. It's easy to blend the two together since both come from Social Security paperwork, but one governs when you can enroll in Medicare and the other governs the size of your monthly Social Security check.

Note your birth year below. It anchors the plan you download at the end of this article to your real full retirement age instead of a number you might be misremembering, and it keeps the checklist and timeline above tied to your actual situation rather than a general rule of thumb.

Building the claiming decision from here

Confirming your full retirement age is the first step, not the whole decision. From there, you're weighing your own health and income needs against how much a delay would grow your check, and whether a spouse's benefit depends on yours. Married couples especially benefit from working through this together, since a higher earner's claiming age can set the floor for what a surviving spouse collects later. None of that math changes because your full retirement age moved. It just means the starting point you're calculating from is a year later than you may have assumed.

This is a separate question from proposals in Congress to raise full retirement age even further, past 67. Those proposals haven't become law, and they're a different, ongoing policy fight over future changes that may or may not happen. What you're working with here is the schedule already locked into current law, already fully phased in, the one that lands at exactly 67 for anyone born in 1960 or later with nothing left pending. Confirming your own real number today doesn't depend on how that separate debate turns out.
