Social Security is a complicated program that far too many retirees don’t understand. One reason why it is so complicated is that annual changes can happen that affect benefit amounts. In fact, a stealth change that occurred in 2026 could end up costing workers thousands of dollars if they aren’t aware of it.
Here’s the change that many people don’t know about, along with some details about what it means for workers who most likely will depend on retirement benefits as a key part of their income in their later years.
This Social Security change could leave retirees with less money over time
The 2026 Social Security change that many workers aren’t paying attention to has to do with when you can claim your standard, unreduced Social Security benefit.
Specifically, retirees are entitled to get their primary insurance amount (PIA) when they hit their full retirement age. The problem is, only 13% of workers know when their full retirement age is. And, as Nationwide research explained, just 13% are aware that their FRA is affected by their year of birth. Americans guessed that FRA was 60 on average, which is far earlier than the reality.
This would be a big enough issue under the best of circumstances, but the consequences are compounded by the fact that full retirement age is changing. Specifically, in 2026, FRA changed to 67 for anyone who hadn’t yet turned 66. Anyone who is born in 1960 or later will have an FRA of 67, while those born in 1959 had an FRA of 66 and 10 months, those born in 1958 had an FRA of 66 and 8 months, and some Americans born earlier had an FRA of 65 or 66.
FRA has been gradually moving later because lawmakers changed the full retirement age in the 1980s to try to stabilize the finances of the Social Security benefits program. But, since far too many people didn’t know their FRA in the first place, they are unaware of this stealth change happening over time — and they don’t realize they have to wait longer than their older counterparts to be able to claim their full Social Security benefit.
The change to full retirement age could cost seniors thousands

A chance to full retirement age may not seem like a huge deal until you understand what this means for retirees. For each month that you claim benefits ahead of your full retirement age, you face penalties. These add up to:
- 5/9 of 1% for each of the first 12 months you claim benefits early
- 5/12 of 1% for any prior month before that time when you claim benefits
For all retirees turning 66 in 2026 or beyond, the end result is that a change from an FRA of 65 (which used to apply to all seniors) to an FRA of 67 will result in seniors having to either wait two extra years to claim their full benefit or face early penalties that add up to around 13.3%. So, those early filing penalties could reduce a standard benefit of around $2,000 to just $1,734. That $266 per month in lost income due to the early claim would amount to $3,192 per year and, over a 30-year retirement, to a grand total of almost $100,000 lost (not factoring in the effects of any Cost of Living Adjustments).
Workers need to be aware of this change to FRA, and should be sure they know when they can claim their full benefit before they claim their Social Security checks, so they don’t make a decision they come to regret.
