Retirement planning runs on assumptions, and few programs generate as many shaky ones as Social Security. Some of these beliefs got their start decades ago and simply never updated. Others spread because the rules genuinely are confusing, full of thresholds and exceptions that don't match everyday intuition.
The trouble is that a wrong assumption about Social Security doesn't just sit there quietly. It can shape when someone files, how they budget, or whether they panic unnecessarily about the program's future. Here are six persistent myths worth clearing up before they shape a decision you can't easily undo.
1. Full Retirement Age Is Still 65

This one refuses to die. A 2025 survey by Allianz Life found that a majority of Americans, 55 percent, still believe the Social Security full retirement age is 65. That hasn’t been true for a long time, and the gap between belief and reality just closed for good.
The full retirement age has been climbing gradually since the 1983 amendments to Social Security, and 2026 marks the final step. In November 2026, the FRA reaches 67 for those born in 1960 or later, capping a 42-year-long shift in raising the retirement age. Anyone who files at 62 still assuming they’ll get a full check at 65 is setting themselves up for a permanent reduction, since claiming at 62 permanently reduces monthly benefits by about 30% compared with waiting until FRA.

This myth causes real anxiety, and it’s understandable given the headlines. But insolvency and extinction are not the same thing. Insolvency does not mean beneficiaries would stop receiving payments altogether, since even after trust fund reserves are depleted, the program would continue collecting payroll tax revenue, allowing it to pay benefits at a reduced level.
The numbers have shifted somewhat in recent reports. Last year’s trustees projected the Old-Age and Survivors Insurance fund would be depleted in 2033, but in August the agency moved the insolvency date to the end of 2032, citing the One Big Beautiful Bill Act’s effect on taxation of benefits. Even then, the Social Security Administration said the agency would pay 78% of benefits upon insolvency, not zero. That’s a serious cut worth planning around, but it’s a far cry from the total collapse many retirees fear.

Plenty of retirees turn down part-time work or freelance gigs because they think earning money will shrink their Social Security forever. It won’t, though there is a temporary wrinkle before full retirement age. If you haven’t reached full retirement age, $1 in benefits is deducted for every $2 you earn above the annual earnings limit of $24,480 in 2026, and in the year you reach FRA, the reduction falls to $1 for every $3 earned above a higher limit of $65,160.
Here’s the part most people miss. The month you hit full retirement age, benefits are no longer reduced no matter how much you earn, and the SSA actually recalculates your payments to include the deducted amounts, resulting in higher benefits going forward. In other words, nothing is truly lost. It’s withheld temporarily, then handed back through a higher monthly check later.
4. Social Security Benefits Are Always Tax-Free

This belief probably traces back to how the program worked for most of its history, but it changed decades ago and the rules haven’t budged since. The Social Security Administration withholds nothing for federal income tax unless specifically asked, and for decades benefits were completely tax-free, but that changed in 1983 and 1993, with thresholds frozen at those original levels ever since.
Those frozen numbers are the real trap. For 2026, single filers with provisional income below $25,000 owe zero federal tax on benefits, between $25,000 and $34,000 up to 50% can be taxable, and above $34,000 up to 85% can be taxable. Because these thresholds are not indexed for inflation and have been frozen since 1983 and 1993, every annual COLA increase pushes more retirees above the thresholds without any legislative action. A modest pension or IRA withdrawal on top of Social Security is often enough to trigger taxation that a retiree never saw coming.

Divorce adds a layer of confusion to Social Security that trips up a lot of people, especially the assumption that filing on an ex’s record somehow takes money away from them. It doesn’t work that way at all. If you are divorced, your former spouse may be eligible to collect benefits on your earnings record and vice versa, and as with benefits for a current spouse, these can be up to 50 percent of the benefit amount you are entitled to at full retirement age.
The key detail is that these are separate calculations entirely. Ex spouse or spouse benefits don’t reduce your Social Security, since they are distinct payments and have no effect on what you receive each month, even if both a current and a former spouse are collecting them. Two people can draw off the same earnings record without either one seeing their check shrink because of it.
6. The Annual Cost of Living Adjustment Is Guaranteed Every Year

Many retirees treat the COLA as an automatic annual raise, something baked into the system no matter what. It isn’t. Since 1975, Social Security law has mandated that payment amounts be adjusted annually to keep pace with inflation, but there is no requirement that this cost-of-living adjustment result in a yearly increase.
The mechanism behind it is narrower than people assume too. The COLA is tied to a federal index of prices called the CPI-W, and benefits are adjusted based on changes from the third quarter of one year to the third quarter of the next, but if the index doesn’t show a statistically measurable rise in prices, there’s no adjustment to benefits. Retirees who assumed the 2.8 percent bump for 2026 would repeat indefinitely at a similar size may be surprised in a low inflation year when the raise is much smaller, or absent entirely.
Getting these six points straight won’t change what Social Security ultimately pays out, but it changes how well a retiree can plan around it. Filing decisions, tax withholding, budgeting for a possible future benefit cut, all of it depends on working from what’s actually true rather than what’s commonly assumed. The program is complicated enough on its own without adding outdated beliefs into the mix.
